Inflation and pandemic recoveries in five major economies

My discussion about current inflation two weeks ago focused on the UK. Over a year ago I wrote a post called “Inflation and a potential recession in 4 major economies”, looking at the US, UK, France and Germany. I thought it was time to update that post for countries other than the UK, with the UK included for comparison and with Italy added for reasons that will become clear. I also want to discuss in general terms how central banks should deal with the problem of knowing when to stop raising interest rates, now that the Fed has paused its increases, at least for now.

How to set interest rates to control inflation

This section will be familiar to many and can be skipped.

If there were no lags between raising interest rates and their impact on inflation then inflation control would be just like driving a car, with two important exceptions. Changing interest rates is like changing the position of your foot on the accelerator (gas pedal), except that if the car’s speed is inflation then easing your foot off the pedal is like raising rates. So far so easy.

Exception number one is that, unlike nearly all drivers who have plenty of experience driving their car, the central banker is more like a novice who has only driven a car once or twice before. With inflation control, the lessons from the past are few and far between and are always approximate, and you cannot be sure the present is the same as the past. Exception number two is that the speedometer is faulty, and erratically wobbles around the correct speed. Inflation is always being hit by temporary factors, so it’s very difficult to know what the underlying trend is.

If driving was like this, the novice driver with a dodgy speedometer should drive very cautiously, and that is what central bankers do. Rapid and large increases in interest rates in response to increases in inflation might slow the economy uncomfortably quickly, and may turn out to be an inappropriate reaction to an erratic blip in inflation. So interest rate setters prefer to take things slowly by raising interest rates gradually. In this world with no lags our cautious central banker would steadily raise interest rates until inflation stopped increasing for a few quarters. Inflation would still be too high, so they might raise interest rates once or twice again to get inflation falling, and as it neared its target cut rates to get back to the interest rate that kept inflation steady. [1]

Lags make the whole exercise far more difficult. Imagine driving a car, where it took several minutes before moving your foot on the accelerator had a noticeable impact on the car’s speed. Furthermore when you did notice an impact, you had little idea whether that was the full impact or there was more to come from what you did several minutes ago. This is the problem faced by those who set interest rates. Not so easy.

With lags, together with little experience and erratic movements in inflation, just looking at inflation would be foolish. As interest rates largely influence inflation by influencing demand, an interest rate setter would want to look at what was happening to demand (for goods and labour). In addition, they would search for evidence that allowed them to distinguish between underlying and erratic movements in inflation, by looking at things like wage growth, commodity prices, mark-ups etc.

Understanding current inflation

There are essentially two stories you can tell about recent and current inflation in these countries, as Martin Sandbu notes. Both stories start with the commodity price inflation induced by both the pandemic recovery and, for Europe in particular, the war in Ukraine. In addition the recovery from the pandemic led to various supply shortages.

The first story notes that it was always wishful thinking that this initial burst of inflation would have no second round consequences. Most obviously, high energy prices would raise costs for most firms, and it would take time for this to feed through to prices. In addition nominal wages were bound to rise to some extent in an attempt to reduce the implied fall in real wages, and many firms were bound to take the opportunity presented by high inflation to raise their profit margins (copy cat inflation). But just as the commodity price inflation was temporary, so will be these second round effects. When headline inflation falls as commodity prices stabilise or fall, so will wage inflation and copy cat inflation. In this story, interest rate setters need to be patient.

The second story is rather different. For various (still uncertain) reasons, the pandemic recovery has created excess demand in the labour market, and perhaps also in the goods market. It is this, rather than or as well as higher energy and food prices, that is causing wage inflation and perhaps also higher profit margins. In this story underlying inflation will not come down as commodity prices stabilise or fall, but may go on increasing. Here interest rate setters need to keep raising rates until they are sure they have done enough to eliminate excess demand, and perhaps also to create a degree of excess supply to get inflation back down to target.

Of course reality could involve a combination of both stories. In last year’s post I put this collection of countries into two groups. The US and UK seemed to fit both the first and second story. The labour market was tight in the US because of a strong pandemic recovery helped by fiscal expansion, and in the UK because of a contraction in labour supply partly due to Brexit. In France and Germany the first story alone seemed more likely, because the pandemic recovery seemed fairly weak in terms of output (see below). 

Evidence

In my post two weeks ago I included a chart of actual inflation in these five countries. Here is a measure of core inflation from the OECD that excludes all energy and food, but does not exclude the impact of (say) higher energy prices on other parts of the index because energy is an important cost.

Core inflation is clearly falling in the US (green), and rising in the UK (red). In Germany (light blue) core inflation having risen seems to have stabilised, and the same may be true in France and Italy very recently. The same measure for the EU as a whole (not shown) also seems to have stabilised.

If there were no lags (see above) this might suggest that in the US there is no need to raise interest rates further (as inflation is falling), in the UK interest rates do need to rise (as they did last month), while in the Eurozone there might be a case for modest further tightening. However, once you allow for lags, then the impact of the increases in rates already seen has yet to come through, so the case for keeping US rates stable is stronger, the case for raising UK rates less clear (the latest MPC vote was split, with 2 out of 7 wanting to keep rates unchanged) , and the case for raising rates in the EZ significantly weaker. (The case against raising US rates increases further because of the contribution of housing, and falling wage inflation.)

As we noted at the start, because of lags and temporary shocks to inflation it is important to look at other evidence. A standard measure of excess demand for the goods market is the output gap. According to the IMF, their estimate for the output gap in 2023 is about 1% for the US (positive implies excess demand, negative insufficient demand), zero for Italy, -0.5% for the UK (and the EU area as a whole), and -1% for Germany and France. In practice this output gap measure just tells you what has been happening to output relative to some measure of trend. Output compared to pre-pandemic levels is strong in the US, has been pretty strong in Italy, has been quite weak in France, even weaker in Germany and terrible in the UK (see below for more on this).

I must admit that a year ago this convinced me that interest rate increases were not required in the Eurozone. However if we look at the labour market today things are rather different. Ignoring the pandemic period, unemployment has been falling steadily since 2015 in both Italy and France, and for the Euro area as a whole it is lower than at any time since 2000. In Germany, the US and UK unemployment seems to have stabilised at historically low levels. This doesn’t suggest insufficient demand in the labour market in the EZ. Unemployment data is far from an ideal measure of excess demand in the labour market, so the chart below plots another: employment divided by population, taken from the latest IMF WEO (with 23/24 as forecasts).

Once again there is no suggestion of insufficient demand in any of these five countries. (The UK is the one exception, until you note how much the NHS crisis and Brexit have reduced the numbers available for work since the pandemic.)

This and other labour market data suggests our second inflation story outlined in the previous section may not just be true for the US and UK, but may apply more generally. It is why there is so much focus on wage inflation in trying to understand where inflation may be heading. Of course a tight labour market does not necessarily imply interest rates need to rise further. For example in the US both wage and price inflation seem to be falling despite a reasonably strong labour market, as our first inflation story suggested they might. The Eurozone is six months to a year behind the US in the behaviour of both price and wage inflation, but of course interest rates in the EZ have not risen by as much as they have in the US.

Good, bad and ugly pandemic recoveries

The chart below looks at GDP per capita in these five countries, using the latest IMF WEO for estimates for 2023.

Initially I will focus on the recovery since the pandemic, so I have normalised all series to 100 in that year. The US has had a good recovery, with GDP per capita in 2023 expected to be five percent above pre-pandemic levels. So too has Italy, which is forecast to do almost as well. This is particularly good news given that pre-pandemic levels of GDP per capita were below levels achieved 12 years earlier in Italy.

Germany and France have had poor recoveries, with GDP per capita in 2023 expected to be similar to 2019 levels. The UK is the ugly one of this group, with GDP per capita still well below pre-pandemic levels, something I noted in my post two weeks ago. Unlike a year ago, there is no reason to think these differences are largely caused by excess demand or supply, so it is the right time to raise the question of why there has been such a sharp difference in the extent of bounce back from Covid. To put the same point another way, why has technical progress apparently stopped in Germany, France and the UK since 2019.

Part of the answer may be that this reflects long standing differences between the US and Europe. Here is a table illustrating this.

Real GDP per capita growth, average annual rates	2000/1980	2007/2000	2019/2007	2023/2019
France	1.8	1.2	0.5	0.1
Germany	1.8	1.4	1.0	-0.1
Italy	1.9	0.7	-0.5	0.8
United Kingdom	2.2	1.8	0.6	-0.7
United States	2.3	1.5	0.9	1.1

Growth in GDP per capita in the US has been significantly above that in Germany, France or Italy since 1980. At least part of that is because Europeans have chosen to take more of the proceeds of growth in leisure. However this difference is nothing like the gap in growth that has opened up since 2019. (I make no apology in repeating that growth in the UK, unlike France or Germany, kept pace with the US until 2007, but something must have happened after that date to reverse that.)

I have no idea why growth in the US since 2019 has been so much stronger than France or Germany, but only a list of questions. Is the absence of a European type furlough scheme in the US significant? Italy suggests otherwise, but Italy may simply have been recovering from a terrible previous decade. Does the large increase in self-employment that occurred during the pandemic in the US have any relevance? [1] Or are these differences nothing to do with Covid, and instead do they just reflect the larger impact in Europe of higher energy prices and potential shortages due to the Ukraine war. If so, will falling energy prices reverse these differences?

[1] If wage and price setting was based on rational expectations the dynamics would be rather different.

[2] Before anti-lockdown nutters get too excited, the IMF expect GDP per capita in Sweden to be similar in 2023 to 2019.

Left behind movements do not just reflect deindustrialisation, but also geography, inequality and lack of representation.

There was extensive analysis after the UK EU referendum of the characteristics of those who voted for Brexit and those who didn’t. A robust finding was that those who voted for Brexit tended to be older and had less years of education. But some noted a link between a tendency to vote Leave and areas of deindustrialisation. The idea of the ‘left behind’ was born. It gained force when rest-belt states in the US swung to Trump in the same year.

This characterisation of the left behind was attractive to many on the left, who have been critical of the globalisation they saw as the cause. Yet as Martin Sandbu points out, the period of what is often called hyper-globalisation is the 1990s, and much deindustrialisation occurred before then. Some of that was a result of automation rather than globalisation, and in the UK 1980s deindustrialisation was hastened by a large appreciation of sterling caused by a combination of discovering North Sea Oil and monetarism. Why the 30 year delay for the left behind to finally find its political voice?

If we look at the geography of the Brexit vote, areas of deindustrialisation is not the only thing that strikes you. Much more obvious is that people in large cities voted against Brexit, and those in smaller cities or towns or the countryside voted for Brexit. The same was true for Trump, and Trumps core support comes from rural areas. Is this simply a consequence of differences in age and education already discussed?

It could well be. As the Centre for Towns showed, UK villages and towns have been getting older and cities have been getting younger. Jobs that attract the university educated tend to be in cities rather than in towns and villages.The old tend to be more socially conservative, and so are attracted to the anti-immigration message that was a key part of the Leave and Trump campaigns.

There is no doubt these factors are important, but do they explain all the the geographical nature of the support for Brexit and Trump, or is there more to it? I think the gilet jaunes from France can shed some light on this question. As John Lichfield outlines, the gilet jaunes come from peripheral France: the outer suburbs and countryside. That may include some areas of deindustrialisation but it goes well beyond that. Their protests are self-organised and remarkably persistent. They do not fit any clear left/right categorisation. Immigration, or race, are not high up among their concerns, which is why they do not feel represented by the far right party of Marine Le Pen.

What do the gilet jaunes want? Specific demands are varied and often contradictory. But a dominant theme is that they want to be valued and represented. They feel that the centres of power in France, the government but also other organisations, do not speak for or even respect them. They think the major cities are getting all the benefits of growth while they are falling behind.

The gilet jaunes tend to be working or lower middle class, sometimes self-employed, sometimes retired. Initially their protests were sympathetically viewed by most French voters, which was one reason why Macron responded with tax breaks for pensioners and low income workers. As time goes on and the violence has continued their popularity among French voters has waned. Whether they have a future as a coherent force may depend on whether they can transform themselves into a conventional political group that wins seats in the forthcoming European elections, a process which has already led to some fragmentation along traditional left/right lines.

Macron’s election as President of France had led many to think that the wave of populism influencing democracies around the world could be held back or even beaten. What the gilet jaunes show is that this cannot be done just by electing a charismatic President. Indeed the character of Macron, clearly part of an affluent city elite, may even have been a provocation.

Can the gilet jaunes tell us anything about those who voted for Brexit or Trump? All three movements come from outside of the main cities, so perhaps geography is more than just an incidental factor. What is unique about the gilet jaunes has been self-organisation, made possible through social media, and the variety of their political demands. In contrast Trump is a Republican, and Brexit is a very specific cause. But perhaps this difference just reflects the ability of some politicians and parts of the media to capture the discontent of the geographical areas that feel left behind?

The EU was not considered an important issue among most voters until the referendum. Immigration was, but a good part of that was because the government and press had managed to deflect anger at declining public services and wages on to immigrants rather than their own policies. Whereas the gilet jaunes had to organise themselves using social media, Brexit and to some extent Trump had sections of the conventional media to do that job. While many gilet jaunes want to overturn the government, Brexit supporters succeeded because they had the help of politicians and the media.

Underlying causes in all three cases include geographical and financial inequality, and a feeling of being ignored by conventional politics. In the UK, looking mainly at the first decade of the century, a NEF report found that nearly all of the 20 fastest growing constituencies were in cities. Often the prosperity of towns depends on the success or otherwise of a nearby city. Those in the periphery see money going to projects like crossrail or HS2 while local bus services are cut.

People look at others to measure their own prosperity but they also look at their own past. In the UK real wages are still below levels before the financial crisis, and in the last year the disparity between the incomes of most people and those at the top of the income distribution has started to increase again. (It is one reason why the Chancellor is getting more tax receipts than he expected.) In the US most of the proceeds of growth have for some time been going to the top of the income distribution.

We can see the same thing, although to a lesser degree, in France. Here is a revealing graph from a study by Thomas Piketty and colleagues. It shows how average annual growth rates of pre-tax income has varied by where people are in the income distribution over three time periods. To the right we have the richer income deciles, including at the end the top 1%, 0.1% and 0.01% respectively. In the two periods before the 1980s incomes at the top grew less rapidly than all other groups. From 1983 to 2014 the opposite has been true: growth rates of top incomes have been up to three times those of everyone else. In addition the growth rate of incomes of the non-rich have been historically low.

Low average growth in most incomes together with much faster growth in incomes at the top is provocative, particularly if you are in parts of the country that are stagnating with few prospects. I do not think it is any coincidence that a week ago we saw the gilet jaunes targeting the exclusive shops and restaurants of the Champs-Élysées.

Inequality based on incomes or geography is not enough to get the gilet jaunes on to the streets, to get UK voters to want to take back control, or Trump voters to vote for the worst President in a century. This also requires a feeling that your voice is not heard in the political process. In the UK a feeling of powerlessness was hijacked by politicians and the press who pretended it was a result of the EU, or in the US by Trump who pretended to speak for ‘real America’.

Speaking up for those left behind should naturally be something parties on the left do. Yet in the UK, as the NEF report shows, Labour have been increasing their vote share in dynamic cities and the Conservatives from areas in decline. This may be part of a longer term trend in both the UK, US and France, where the left party that once represented the less educated now is the party of the educated. The chart below taken from another study by Piketty shows this trend, which he calls it the emergence of the “Brahmin Left”.

Yet I think this alone is an incomplete explanation. To explain recent developments we should add the adoption by traditional left parties of a neoliberal framework which discouraged regional, industrial and redisributive policies that might have transferred more of the benefits of city dynamism to the periphery. That created a left behind that went beyond areas of deindustrialisation, that felt unrepresented and deprived, and which in the UK and US was open to capture by a populist right.

How the left stopped being a party of the working class

I’ve been meaning for some time to write about a recent paper by Thomas Piketty, which looks at what characteristics influenced voters to vote for the left or right in France, the UK and US since WWII. (Simon Kuper has a nice little summary with a great title.) Here is a chart that shows how after WWII educated voters tended to vote right, but now tend to vote left (even after controlling for income, age etc - see box)

In all three countries, the number of educated voters increased in all three countries, reflecting in part the need for higher skilled workers.

In contrast (and if we exclude the most recent elections in France and the US) the income profile for voting has not changed very much over time: poorer voters are more likely to vote left than richer voters, particularly if we control for education, although poorer voters are increasingly unlikely to vote. So the shift in voting patterns among educated voters demands an explanation and has fascinating implications.

Unfortunately the paper does not focus on this question, but it does suggest that part of any explanation may reflect the fact that more educated voters tend to have more liberal attitudes in general, and more liberal attitudes to migration in particular (see here for example). The positive correlation between social liberalisation and education is well documented (see [1] for example), as was evident in the Brexit vote.

I suspect there are other factors as well. There are possible reasons why the interest of human capital (as economists would call it) are different from the interests of business or financial capital, or no capital at all. For example a more meritocratic education system suits them better than one where income buys education, so they are likely to be stronger supporters of a state based education system (or indeed they may be part of it). They will also be more likely to consume state subsidised culture. More generally there may be a wish to break down traditional class based networks and replace them with more meritocratic structures. On the other hand because human capital generates an income, they will be less keen on tax based redistribution than workers. All this may create what some might call an education ‘cleavage’.

The implication for parties on the left are that party members were increasingly from the educated middle class rather than working class, and this has gradually changed the structure, platforms and leaders of left parties. Together with the decline in trade unions, the counterpart to this will be a less visible representation of the working class. Piketty describes this as the emergence of the “Brahmin Left” elite, which can be compared to the “Merchant” elite on the right.

A consequence may be that the political elite as a whole becomes less interested in redistributive policies that used to favour the working classes, and helped continue the decline in wealth inequality before the 1980s that Piketty has famously documented elsewhere. That in turn makes it easier for the right to capture parts of the working class vote, particularly when these voters have socially conservative views. A recent book by Mark Bovens and Anchrit Wille takes a very dim view of these changes.

There is a less pessimistic take on all this. As right wing parties have increasingly relied on pushing socially conservative/authoritarian/anti-minority policies to gain votes, left wing parties find that this combined with wealth/income protection is an unbeatable coalition for their opponents. (Perhaps this helps explain the decline in so many centre-left European parties.) The only way to beat that coalition is to rediscover economic policies that help the working class.

This long paper has other interesting results. In France, like the UK, public attitudes have seen a decreasing hostility to immigration over time. He also notes that the right’s socially conservative turn has helped to sustain an almost complete loyalty to the left from Muslims in the UK and France, and from blacks in the US. Finally a parochial point of interest, which is also a point that Torsten Bell has stressed recently.

Piketty notes that the dominance of the left among the young in the UK in 2017, as well as being unprecedented in the UK, was higher than in any of the two other countries at any point in time. It may be that this is part of a trend since 1997, but it could be exceptional because of Brexit, which amounts to the old taking opportunities away from the young.

Fiscal policy remains in the stone age

Or maybe the middle ages, but certainly not anything more recent than the 1920s. Keynes advocated using fiscal expansion in what he called a liquidity trap in the 1930s. Nowadays we use a different terminology, and talk about the need for fiscal expansion when nominal interest rates are stuck at the Zero Lower Bound or Effective Lower Bound. (I slightly prefer the latter terminology because it is up to central banks to decide at what point reducing nominal interest rates further would be risky or counterproductive.) The logic is the same today as it was in the 1930s. When monetary policy loses its reliable and effective instrument to manage the economy, you need to bring in the next best reliable and effective instrument: fiscal policy.

The Eurozone as a whole is currently at the effective lower bound. Rates are just below zero and the ECB is creating money for large scale purchases of assets: a monetary policy instrument whose impact is much more uncertain than interest rate changes or fiscal policy changes (but certainly better than nothing). The reason monetary policy is at maximum stimulus setting is that Eurozone core inflation seems stuck at 1% or below. Time, clearly, for fiscal policy to start lending a hand with some fiscal stimulus.

Yet the goal of the new German Finance minister, from the supposedly left wing Social Democrats, is to achieve a budget surplus of 1%. To achieve that he is cutting public investment from 37.9 billion euros in the coming year to 33.5 billion euros by 2020. Yet German infrastructure, once world renowned, is falling apart. Its broadband connectivity could be greatly improved.

The macroeconomic case for a more expansionary German fiscal policy is overwhelming. Germany has a current account surplus of around 8% of GDP. There are some structural reasons why you might expect some current account surplus in Germany, but the IMF estimates that these structural factors account for less than half of the current surplus. It estimates that a third of the excess surplus is a result of an overly tight fiscal policy. As Guntram Wolff points out, the main counterpart to the surplus is saving by the corporate sector. Perhaps more public investment might encourage additional private investment.

But this is not another article about how Germany needs to expand to help the rest of the Eurozone. The problem, as Matthew Klein points out, is that the whole of the Eurozone is doing the same. In the area as a whole, the fiscal position is as tight as it was in the pre-crisis boom. Unemployment in the Eurozone is still too high. And the reason fiscal policy is too tight is that key Eurozone policymakers think that is the right thing to do. “The right deficit is zero” says the French finance minister. He goes on: “ Since France is not in an economic crisis, we need to have a balanced budget, so that we can afford a deficit in tougher times.” You hear the same in Germany: the economy is booming so we must have budget surpluses.

A booming economy is not one that is growing fast, but is one where the level of output and employment is above the level compatible with staying at target inflation. Measures of the output gap are only estimates of what that level is: underlying inflation is the ultimate guide. Core inflation is well below target right now, which is why interest rates are at their effective lower bound. This is why the actions and rhetoric of most European (and UK) finance ministers are simply wrong.

You would think that causing a second recession after the one following the GFC would have been a wake up call for European finance ministers to learn some macroeconomics. (Yes, I know that the ECB raising rates in 2011 did not help, but I expect most macro models will tell you the collective fiscal contraction did most of the harm.) Yet what little learning there has been is not to make huge mistakes but only large ones: we should balance the budget when there is no crisis.

This is not a dispute between left and right as it is now in the UK, but a problem with the policy consensus in Europe. What we are seeing I suspect is a potent combination of two forces: a German obsession with balancing the budget which has it roots in currently dominant ordoliberal/neoliberal ideology, and Keynes famous practical men: advisers who learnt what economics they have in an era of the great moderation where the worst economic problem we had was relatively benign deficit bias. Fighting the last war and all that.

House prices and rents in the UK

I am not a housing expert, but it seems to me that the public debate is completely confused because it fails to make the distinction between house prices and rents. If we are talking about the supply and demand for housing, the price that equates those two things is rent, not house prices.

I discussed why here, but let me summarise the argument. Rent reflects the cost of being housed, of having a roof over your head. If there are less houses to go around, rents will be higher: higher enough to make some people share flats, live with parents or whatever. Because houses to buy can quickly change into houses to rent, there are not really separate markets for buying and renting, but just one big housing market.

The price of a house is the price of an asset. The asset in this case provides a roof over your head for as long as you own it. This means that house prices depend on current and future rents. Crucially, however, like any asset, the price is the discounted sum of future rents, where the discount rate is the real rate of interest. If real interest rates fall but future real rents stay unchanged, housing becomes a more attractive asset, and so wealthy people will buy more houses, pushing the price up.

Below is a chart of the ratio of house prices to rents in the UK and France, from OECD data.

There are large swings, but no major trend before around 2000. (That may surprise people, but it reflects what has happened to rents which we will come to.) In the early years of this millenium the house price to rent ratio increased substantially in both countries, and has stayed higher. I have included France with the UK to suggest that there may be some common factor influencing their similar behaviour. [1]

That common factor is real interest rates. You can define real interest rates many different ways: here I’m just going to be very lazy and pull data from the World Bank.

Again ignore the details (I have no idea about 1995) and focus on the trend. Around 2000, real interest rates started falling, and falling substantially. As real interest rates fall, house prices rise.

This will only be true if the housing market is liberalised so that this kind of arbitrage works, and that there are no taxes that stop the arbitrage happening. That was not the case in the UK before the 1980s (mortgages were rationed when I bought my first house), which is just one reason why you would not expect this relationship to hold over that period. But in the last two decades, lower returns on other assets has seen the rise of the middle class landlord as a way of saving for retirement.

This substantial fall in real interest rates is a worldwide phenomenon, and it goes by the name of secular stagnation. Why it has happened and to what extent it is permanent is still the subject of lively debate, which is beyond the scope of this post. The key test will be when nominal interest rates begin to rise over the next few years: to what extent do real interest rates rise with them. All I can say for sure is do not rely on those who say house prices always rise over time.

Thus the rise in house prices in the UK and France since 2000 has got little to do with a lack of house building, a point that Ian Mulheirn has stressed. But what about rents, which is where we should look for any imbalances in supply and demand. Here is some IFS data from a recent paper by Robert Joyce, Matthew Mitchell and Agnes Norris Keiller.

Outside London, there has not been a rise in the proportion of income spent on rent. Essentially, and I suspect this applies before the mid-90s, housing costs (rents) have risen with earnings rather than prices, and at constant real interest rates that would mean house prices rising with earnings. This represents a very reasonable return on any asset, and is why we think buying a house is a good investment. Now you could argue that we should build enough houses so that this proportion of income spent on housing falls, as it has for food for example. What you cannot argue is that building too few houses has anything to do with why houses have suddenly become unaffordable to young people.

The situation for rents has clearly been different in London in recent years, and London house prices have also risen much faster than elsewhere. David Miles and colleagues have written an interesting paper on how house prices in cities can rise as more people work in them but transport costs do not fall. In recent years UK governments have been trying to reduce the subsidy for train travel, and higher rents are a natural consequence. One way to reverse this is to invest in new and improved transport links into cities. However I think the main reason that house prices have recently risen in major cities in many countries is the decline in real interest rates noted above. (Here is the same debate in Vancouver.)

Does secular stagnation (low real interest rates) mean that a whole generation has to rent rather than buy? The main problem is the deposit that first time buyers have to find. Low real interest rates mean a mortgage is easier to service once you have one, although low rates of nominal earnings growth mean that it doesn't get so much easier over time as it used to. But rising prices means rising deposits, which if parents cannot help means saving for a long time. Banks do not want to take the risk of lower deposits, particularly if there is a real chance that house prices could fall. Help to Buy is about the state taking over the risk that Banks will not take, but is that something we collectively want to do? That is the debate we should be having in an age of secular stagnation. Building more houses may or may not be fine, but if real interest rates stay low it is not going to make houses affordable again for the generation that can no longer buy a home.

[1] It is fascinating to look at the countries that are similar to the UK and France, and those that are not (like the US and the Netherlands, but especially Germany). If anyone can tell me why these countries have not seen a permanent upward shift in house prices I would love to hear it.

The French election and two-dimensional politics

Unless something very surprising happens, the French presidential election will be between Marine Le Pen of the Front National and François Fillon, who recently won the primaries for a collection of parties (essentially the right wing republican party). Fillon’s platform was extremely neoliberal. As Renee Buhr describes here:

“His policy proposals largely indicate a small government, low taxation and free market approach to economic policy, while his campaign rhetoric takes aim at the usual ‘boogeymen’ cited by liberal politicians – government regulations, public expenditures, high taxes and public sector institutions and employees.“

This makes we worried that Le Pen will win.

If you see politics as all about a left/right axis, my concern makes no sense. Choosing someone whose economic policy is very much to the right of the centre/right parties should eat into Le Pen’s support, while those on the left will vote (reluctantly) for the lesser of the two right wing parties. However this one dimensional view is far too simplistic, and perhaps fatally so in this case.

To illustrate why, I want to briefly look at a piece by Jonathan Wheatley, which uses UK politics before the 2015 election. A sample were asked their views on 30 different policy issues. A technique was then used to find a pattern in the responses. The first interesting result was that the strongest pattern was two dimensional: there seem to be two common factors underlying these responses. To quote:

“The first is an economic dimension, drawing on issues such as the mansion tax, the bedroom tax, and privatisation of the NHS. The second is a cultural dimension, drawing on issues such as EU membership, immigration, same-sex marriage and English Votes for English Laws.”

We could say the cultural dimension was about identity, varying from communitarian to cosmopolitan views. He then looks at the political party people supported. Here is the result:

On the cultural dimension, party supporters are where you would expect. But on economic issues UKIP supporters are less rather than more right wing than Conservative party supporters.

I know of no similar analysis that looks at French voters, but this does not matter for the point I want to make. Suppose we use the same diagram to represent a political party's policy position. In that case the area occupied by UKIP in the diagram above does seem to correspond to Front National policies. Their position on the identity axis is certainly well to the south of other parties, but their position on economic issues is far from neoliberal. In choosing who to vote for, the voter will position themselves on the diagram, and look for the party that is closer to them in this two dimensional space. (Of course we cannot use the diagram to actually measure distance, as the implicit weighting between the two aspects is arbitrary, and may not correspond to that of the voter. But the conceptual argument still works.)    

From this two dimensional perspective, choosing a candidate to oppose Le Pen who is pretty right win in economic terms does nothing to capture Front National voters. But more seriously, it risks losing the support of left wing voters. While they may dislike Le Pen because of her stance on immigration and other identity issues, Le Pen is more acceptable in terms of economic policies than a very neoliberal candidate.

Eurozone fiscal policy - still not getting it

The impact of fiscal austerity on the Eurozone as a whole has been immense. In my recent Vox piece, I did a back of the envelope calculation which said that GDP in 2013 might be around 4% lower as a result of cuts in government consumption and investment alone. This seemed to accord with some model based exercises of the impact of austerity as a whole, but others gave larger numbers.

We now have another estimate, which can be thought of as a rather more thorough attempt to do what I did in the Vox article. This paper by Sebastian Gechert, Andrew Hughes Hallett and Ansgar Rannenberg uses multipliers and applies them to the fiscal changes that have occurred in the Eurozone from 2011. Apart from the later start date, the first difference compared to my back of the envelope calculation is that they include all fiscal changes, and not just government consumption and investment. As a large part of the fiscal consolidation in the Eurozone has involved reducing fiscal transfers, this is important.

The second, and more interesting, difference is that rather than pluck a multiplier out of the air, as I did, they use a meta analysis of other studies. I have previously mentioned this meta analysis by Gechert: this paper is based on a follow up by Gechert and Rannenberg. [Correction from original post.] The studies on which these meta analyses are based are not ideal from my personal point of view (more on this later), but what this second paper shows is that fiscal multipliers are larger in depressed economies. Applying these ‘meta multipliers’ to the Eurozone fiscal consolidation implies that GDP was 7.7% lower by 2013 as a result. These numbers are more in the ballpark of the Rannenberg et al paper that I have discussed before.

All these estimates point to huge losses, which monetary policy has neither been willing or able to counteract. Yet the speed at which those in charge of the Eurozone begin to realise the mistake that they have made is painfully slow. Take this recent Vox piece by Marco Buti and Nicolas Carnot. Thankfully they ignore all the Eurozone’s tortuous and sometimes contradictory rules, and just look at two numbers: a measure of ‘economic conditions’ (like the output gap), and a measure of the fiscal gap, which is the difference between the actual primary balance and what it needs to be to get debt falling gradually.

They argue that policy needs to balance the need to reduce both gaps. Looking at these two numbers, they conclude that Germany is overachieving on fiscal adjustment and has a need to increase activity, but although France and Spain also need to increase demand they have a long way to go to eliminate the fiscal gap, so this should dominate. The conclusion is that Germany should go for fiscal stimulus, but “moderate consolidation appears warranted in both France and Spain”. Overall “the Eurozone should conduct a close-to-neutral fiscal stance”.

Let’s deal with that last conclusion first. The mistake there is simple. When monetary policy is stuck at the Zero Lower Bound, it is crazy to balance the output gap with what is your main instrument for correcting that gap, which is fiscal policy. Getting the fiscal gap right is important in the longer term, but in the short term it is the means by which you get the output gap to zero. As the studies mentioned at the beginning of this post show, the current recession is the result of trying to correct the fiscal gap at completely the wrong time. The right policy is to get the output gap to zero, so interest rates can rise above the ZLB, and then you deal with the deficit. Readers of this blog and the blogs of others must be sick and tired of seeing us make this same point over and over again, but the logic has yet to get through to where it matters.

The same principles apply to countries within the Eurozone, except with an additional complication of within Eurozone competitiveness. If a country is too competitive relative to the rest of the Eurozone, it needs to run a positive output gap for a time to generate the inflation that will correct that position, and vice versa. For that reason Germany needs a large positive output gap at the moment (compared to an estimated actual negative gap), and therefore a much more expansionary fiscal policy - not because it is overachieving on debt adjustment. France and Spain now look roughly OK in terms of competitiveness relative to the average (see chart below, and assuming that entry rates in 2000 were appropriate), so there we need fiscal expansion to close the output gap.

So at both the aggregate and individual country level, the inappropriate bias towards fiscal contraction that caused huge losses in the Eurozone in the past continues to operate. Which means, unfortunately, that the needless waste of resources caused by austerity continues to get larger by the day.
