Mainly German links

The Bundesbank wants higher wages in Germany (really!).

The ‘Statistisches Bundesamt’ has a kind of app which helps companies to use data on historical inflation to insert ‘real price’ clauses in contracts – which can lead to a ‘price-price’ spiral. Interesting, as many economic models suppose that historical inflation is caused by expectations about future inflation (really!).

The German Handelsblatt has a very interesting article (sorry, no link) about business credit in the north (+1,4%) and the south (-5,9%) of the Euro Area. Which shows the difficulties of monetary policy in the Euro Area: one size fits none.

Eurostat published, coincidentally on July 17, data on EU energy imports from Russia. 39% of EU imports of natural gas and 34% of oil imports come from Russia. Also (including re-exports):

For seven Member States (Bulgaria, Czech Republic, Finland, Hungary, Lithuania, Poland, Slovakia) more than 75 % of their petroleum oils imports came from Russia. Twelve countries (Austria, Bulgaria, Czech Republic, Estonia, Finland, Hungary, Latvia, Lithuania, Poland, Romania, Slovakia, Slovenia), imported more than 75 % of total national imports of natural gas from Russia.

Price increases caused a surge in imports from Russia from 80 million euro in 2005 to 140 billion in 2013.

Bubble days are here again – time for a land tax

July 15, 2014 3 comments

Recently, Eurostat published data on European house prices. Prices are, on average, falling with 0,3%, Year on year. Which is a good thing, especially for the young ones. More good news: deflated Euro area and European Union house prices indexes are however about 12% lower than at the height of the bubble, in 2007. I’m of the opinion that young people establishing a family should not be burdened with paying high tributes to the middle aged and elderly or to banks reaping unearned rent incomes! Houses have to be and can be affordable (and available) and lower prices in combination with lower interest and, in a number of countries, a limited increase in nominal wage rates did lead to increased affordability (the idea that low interest rates necessarily have to lead to high house prices is bad economics!). Good.

However – signs of exuberance are returning. These increases are, as such, maybe not yet alarming. But whenever they are associated with rising private debt – we’re in trouble.

house prices

And part of these increases are alarming. Prices in London (which is about ten times as large as Estonia) ewcwntly increased with 20% YoY, a record. In Dublin (where prices declined during the crisis, but not to anything like a low level), prices are increasing at a double-digit rate, too. The 2013 the German rate of change seems to be about 10% (Eurostat does not have recent German data), though the most recent data seem to indicate that this rise has abated. Read more…

In neoclassical DSGE models, coastal defences are ‘wasteful’. A reply to June Sekera

July 11, 2014 21 comments

Dear mrs. Sekera,

thank you for your very clear and insightful blogpost on this blog about economists and their distorted concept of public goods. But I’m afraid you’re way to positive about at least mainstream macro models and ‘public goods’. Very often – these models do not have a concept of public goods.

Too often, neoclassical ‘macro’ models do not have any logical space for public goods or ‘government consumption’ (i.e. consumption by households produced or financed by the government, like education) at all. Which is daft. My country – the Netherlands - would not even exist without coastal defences. And believe me – we learned about the necessity of well maintained large-scale public coastal defences the New Orleans hard way (Knibbe, forthcoming). But in the default DSGE (Dynamic Stochastic General Equilibrium) models, public expenditure on coastal defences is, by definition, ‘wasteful’ – as it’s government expenditure. You are attacking Samuelson – but Samuelson in fact crafted his ideas – which as you state do have basic flaws – to combat exactly this kind of thinking! But he failed. This kind of thinking is alive and kicking. And kicking hard – as the over five million unemployed in Spain can testify. Even incorporating the ideas of Samuelson into these models would be a huge step forward – these at least consider the existence of public goods and services.

The Oosterscheldekering coastal defence. Wasteful?

Brouwersdam

There are endeavours to change this. But the very fact that these articles have to state, in an explicit way, their difference with ‘standard’ neoclassical ‘macro’ by introducing the notion that public expenditure can serve a purpose shows the ‘state of the mainstream art’: Read more…

The UK productivity decline is over

July 6, 2014 1 comment

The ONS has published new data on British productivity. These show that the unprecedented 5% productivity decline has to quite an extent a lasting nature as it was mainly located in finance and the oil industry, which means that potential GDP also declined with the same amount. According to the ONS,

New analysis of industry contributions to productivity movements since the economic downturn shows large negative contributions from production industries other than manufacturers and from the financial services industry.

See also my take on this from a year ago (including productivity graph). Look also here. Productivity has however started to increase again, which means that potential GDP, though lower than before 2008, is increasing again (Okun’s law) while the surprising increase of British employment is not due to special productivity lowering British labour market mechanics (the British labour market is not special, despite flexibility) but to buoyant demand in non-financial, non-oil sectors (possibly to an extent caused by lower income inequality):

UK labour productivity was little changed in the first quarter of 2014, as growth of labour inputs broadly matched the expansion of economic output. Output per hour grew by 0.2% in the first quarter in service industries, and by 0.5% in production industries

The rise in productivity was to be expected.

Internal *revaluation* in the Baltics

For quite some time Latvia was an austerity and internal devaluation poster child. Lately, however, the voices lauding ultra-unemployment and the crushing of already very low wages have silenced – as wages are rising rapidly. For a time I suspected, cynically, that this wage shock might be a cunning plan of these sly Baltics – once they joined the Euro they increased their wage level (Latvia business economy wages increased at a healthy 7% rate, 2014 Q1 (Eurostat), directly after Latvia joined the Euro), to obtain a free Bratwurst.

Bratwurst

But this was probably not the case. According to a new NBER working paper by Cavallo, Neiman and Rigobon, market forces might be at work. Joining the Euro seems to lead to a fast convergence of price levels:

Does membership in a currency union matter for prices and for a country’s real exchange rate? The answer to this question is critical for thinking about the implications of joining (or exiting) a common currency area. This paper is the first to use high-frequency good-level data to demonstrate that the answer is yes, at least for an important subset of consumption goods. We consider the case of Latvia, which recently dropped its pegged exchange rate and joined the euro zone. We analyze the prices of thousands of differentiated goods sold by Zara, the world’s largest clothing retailer. Price dispersion between Latvia and euro zone countries collapsed swiftly following entry to the euro. The percentage of goods with nearly identical prices in Latvia and Germany increased from 6 percent to 89 percent. The median size of price differentials declined from 7 percent to zero.

Just published: the scientific answer of the ECB to the crisis

The ECB published a report on the results of the Macro Prudential Research Network. It’s the scientific answer of the ECB to the crisis: what has to change in our view of the economy? Considering the subject the paper, basically a dense abstract of post 2008 ECB research on this subject, is well written, though it’s clearly not intended for people who haven’t finished economics 101 (or 202).

I have read only a few of the many reports cited in this paper. Based upon the little I’ve read and the paper itself the next things can be stated about this potential pathbreaking (it’s intended to be pathbreaking!) piece of economics:

It’s a step away from rational expectations and general equilibrium: good.  It tries to model the financial sector using insights of people like Minsky and Kindleberger: good. It does not just pay attention to the flow economy but also to the stock economy (debts, assets like houses): good. It tries to model a financial sector: good. Despite the fact that the monthly monetary statistics of the ECB are totally endogenous by nature and based upon the idea that credit and money are two sides of the same coin (of course they are, as they try to measure the real world), endogenous money still seems to be a bridge too far: bad (but I, or the person who wrote the abstract, might have missed something). Not enough attention is given to the ECB reports on international trade, which again and again show that lowering wages is not the way towards buoyant exports. Lower wages do decrease imports, as domestic expenditure goes down (duh….). But they do not lead to any noticeable break in the long run pattern of export growth (Spain!). The reader should be aware that a ‘VAR’ is a multidimensional moving average. Caveat (again): I did read only a few of the research papers behind this impressing document.

The policy take away: money (and monetary credit) matters. It’s not just a ‘veil’ over the real economy. To be precise: it’s not a ‘classical’ veil. Read Minsky (1992) about this (who bases his view on Schumpeter (1933), Fischer (1934), Keynes (1936), Kindleberger (1978). The insights above are, when push comes to play not exactly fresh and pathbreaking – but a rediscovery of received wisdom. Not too little – but too late. As millions of needless unemployed in the Euro Area can testify.

Low interest rates? What low interest rates (3 graphs)! The BIS is very wrong about the Euro Area.

Is the BIS right to warn about the long run dangers of long-term ultra accommodative monetary policies? Yes. But the BIS is wrong about the Eurozone. Interest rates policies in the Eurozone are not ultra-accommodative. They are only starting to become normally ‘accommodative’ – and not even for everyone. Also, not that long ago (the summer of 2012), ultra tight monetary policy almost led to the disorderly break up of the Euro Area. Eurozone monetary policy has not (repeat: not) led to ‘ultra accommodative’ interest rates and we’re only starting to recover from grave policy mistakes which induced tightening in the midst of the most severe post WW II recession to date.

* though banks have been paying low rates for quite some time now (and even these were increased, back in 2011…)
* it is has only been since some months that the same holds for the governments of, for instance, Spain, Italy and Greece. Rates paid by these countries were, totally unnecessary, immorally and destructively high and a main cause of the present Euro Area mess (graph 1 – as can be seen government rates were 7%-points higher in Italy than in Germany – while at that time inflation and government debt in both countries was about equal

Borio and Disyatat: beware, money matters (and not just because of debts)

June 28, 2014 1 comment

Claudio Borio and Piti Disyatat are concerned about low interest rates. Hmmm… At this moment, the Euro Area is deleveraging – despite ultra low interest rates, the German economy is doing only moderately well, at best, despite ultra low-interest rates, while the level of unemployment in countries like Greece and Spain is almost 20%-point above the level where any meaningful ‘Phillips curve’ (i.e. a relation between unemployment and nominal wages) still exists – despite ultra low interest rates (well, not for Greek and Spanish companies, of course). And at the moment house prices are, on average, slowly declining, while before 2009 dislocating house price inflation was arguable not so much caused by lower interest rates but by lending deregulation.

Still, their warnings should be taken serious – as there is no such thing as a natural rate of interest. As an example of ‘malinvestments’ during the boom phase associated with a subsequently unsustainable debt overhang as well as idle capital, a graph of house completions in Ireland (how could Irish economist ever miss that bubble, why do mainstream economists sometimes still argue that bubbles do not exist – read Borio and Disyatat) is added (house completions in the entire UK reached a peak level of 219.000 in 2006/2007). See also the latest J.W. Mason blogpost about interest rates, which more or less states that people are not searching for yield – but use their trust in money, the monetary system, the guarantee of the cyclical dynamics of money as well as prevailing monetary yields as a foundation to act upon (possibly guided, to an extent, by ‘animal spirits’, M.K.?) – which fits into the Borio/Disyatat story (or the other way around).  Read more…

Anti-austerity links, ‘economists hate to say ‘I should have told you so” edition

June 27, 2014 3 comments

A) Greece: past Dickens. Supposed to happen when the monetary system fails you. See below.

B) The British consumption conundrum: not foretold but supposed to happen, considering the change in the income distribution. Conundrum solved. See below.

C) Voxeu: Eurozone austerity is self-defeating (A) - self-fulfilling crisis edition. It’s not different, this time.

D) Voxeu: Eurozone austerity is self-defeating (A) – debt deflation edition. Which we have known since the thirties (Irving Fisher actually already warns about ‘debt deflation’ in the beginning of the twenties (second edition of this)). The tens of billions which the Greek government was forced to borrow to recapitalize the banks, which was needed to plug their government debt restructuring induced capital shortage are not mentioned.

E) (No) investments in Greece, graph below. Investment in new dwellings declined to 10% of the peak level. Well, that was slightly unexpected – but in Ireland this happened, too.

Ad A) From Zero hedge and based upon a labour union investigation(h/t: David Taylor): this is what real, Great Depression like deflation looks like. The Greek are forced to use barter and to reinvent kinds of money and it’s not a pretty sight (for those who still believe the assumption of quite some neoclassical models that all companies use the same technology and only compete on (wage)costs: read recent ECB studies on competitivety, which are entirely consistent with the empirical findings from Salter in the sixties (in fact: fifties, it was published in 1960)):  Read more…

Debt deflation in action: Greece

Household debt in Greece is  pretty low (70% of GDP, 2013), at least compared with countries like the Netherlands (139%, 2012), Denmark (149%, 2012) or Ireland (112%, 2012). Also, after 2010 Greek households paid down 24 billion of debt (part of this decline might be due to debts being written off by banks), despite of this debt as a % of GDP debt increased since 2010 as nominal GDP (a measure of total income) went down.  While nominal debt is about as high as in 2007/2008, the index of debt as a % of GDP is about 40%-points higher (as a % of GDP it increased from about 55% to 70%).

Oh my. Do DSGE economists really misunderstand the concept of ‘government consumption’?

June 22, 2014 7 comments

Do DSGE economists really exclude ‘government consumption’ from their concept of household prosperity? Yes, they do.

Scientific economists explain ‘government consumption’ as follows:

Government acquisition of goods and services for current use to directly satisfy individual or collective needs of the members of the community is called government final consumption expenditure (GFCE.) It is a purchase from the national accounts “use of income account” for goods and services directly satisfying of individual needs (individual consumption) or collective needs of members of the community (collective consumption). GFCE consists of the value of the goods and services produced by the government itself other than own-account capital formation and sales and of purchases by the government of goods and services produced by market producers that are supplied to households – without any transformation – as “social transfers” in kind.

Source: Wikipedia, which shows that this isn’t any kind of secret – it’s  has been ‘received wisdom’ since the fifties of the twentieth century.

Also, total, i.e. individual (education) plus collective (property rights) government, consumption is a well-defined and fully measured part of the National Accounts. It’s not like a fuzzy, unmeasurable, pre-scientific concept like neoclassical ‘utility’. Look here for the most recent Eurostat estimates of  what’s called ‘Actual Individual Consumption’: Read more…

Piketty and the fixed-investment rate

A central argument of Piketty is the idea that if ‘r’, the realized return on all kind of capital (houses, bonds, stock, land,…) turns out to be larger than the rate of growth, capital, estimated as a % of total GDP, will tend to increase as the extra money can be reinvested in new capital (or (via securitized mortgages?) increase prices of existing capital: the famous ‘search for yield’).

What does LSE mean?

June 20, 2014 2 comments

From: Peter Radford

I just received an email from the London School of Economics asking me to donate, as a loyal alumni, so that they can devote funds to “innovation”. The university of the future seems to be the objective of this innovation.

What on earth is this?

What about higher education needs innovating?

Why the imperative?

I understand that higher education productivity measured in business terms is, to be blunt, weak. And I understand that more modern techniques as enabled by digital technologies will, no doubt, disintermediate education and make the classic class/lecture room setting look antiquated. But what are the consequences?

For universities.

For students.

For teachers. Read more…

The British recovery. No conundrum there… (4 graphs)

June 20, 2014 1 comment

The British economy has not yet recovered in any meaningful sense of the word. Production per capita is not back to historical levels, private debts are still sky-high, the number of crappy jobs is increasing and productivity is about 7 to 8% below ‘trend’ (a downward adjusted trend, that is), which is of course consistent with the increase of crappy jobs. Also, according to the PSE

The percentage of households who fall below society’s minimum standard of living has increased from 14 per cent to 33 per cent over the last 30 years, despite the size of the economy doubling. This is one of the stark findings from the largest study of poverty and deprivation ever conducted in the UK. Other key figures reveal that almost 18 million people cannot afford adequate housing conditions; 12 million people are too poor to engage in common social activities; one in three people cannot afford to heat their homes adequately in the winter and four million children and adults aren’t properly fed by today’s standards …  full-time work is not always sufficient to escape from poverty.

Links. The UK recovery , ‘extrinsic unpredictability’ and models, social protection, labour market

1) Tyler Cowen is slightly bullish about the UK economy and calls it a ‘classical’ recovery, i.e. caused by market induced changes in relative prices. Cowen mentions the labour market but forgets about the decline of the price of the British pound (and about the recent house price bubble, too – though house prices estimated in Euro of course declined more/increased less, post 2008).

Robert Skidelsky on the economics curriculum

June 19, 2014 13 comments

According to Brad deLong, ‘the extremely wise Robert Skidelsky has an excellent rant against Anglo-Saxon economics departments‘, on Project Syndicate. First a Skidelsky excerpt, below this some Brad.

The deeper message is that mainstream economics is in fact an ideology – the ideology of the free market. Its tools and assumptions define its topics. If we assume perfect rationality and complete markets, we are debarred from exploring the causes of large-scale economic failures. Unfortunately, such assumptions have a profound influence on policy.

The efficient-market hypothesis – the belief that financial markets price risks correctly on average – provided the intellectual argument for extensive deregulation of banking in the 1980s and 1990s. Similarly, the austerity policies that Europe used to fight the recession from 2010 on were based on the belief that there was no recession to fight.

These ideas were tailored to the views of the financial oligarchy. But the tools of economics, as currently taught, provide little scope for investigating the links between economists’ ideas and the structures of power.

Today’s “post-crash” students are right.: Read more…

Beveridge curves for the European Union (kudos to Eurostat)

Yesterday, Eurostat published (new!) Beveridge curves for the European Union. The data suggest to me that the curve is essentially horizontal when unemployment is higher than 10%, regardless of the institutional structure of a country. Which means that trying to make labour markets more efficient will not lead to a lower job vacancy rate and, i.e., not to a (short-term) employment gain. An ‘efficient’ labour market is not necessarily the same thing as a ‘flexible’ labour market, see the Eurostat remarks below the graph. Efficiency gains might be possible in the UK, Belgium and Germany, see however the Eurostat remarks below the graph .

What — really — is ‘effective demand’?

June 18, 2014 5 comments

from Lars Syll

J__Jespersen_683346aEconomists of all shades have generally misunderstood the theoretical structure of Keynes’s The General Theory. Quite often this is a result of misunderstanding the concept of ‘effective demand’ — one of the key theoretical innovations of The General Theory (chapter 6, M.K.)

Jesper Jespersen untangles the concept and shows how Keynes, by taking uncertainty seriously, contributed to forming an analytical alternative to the prevailing neoclassical general equilibrium framework:

Effective demand is one of the distinctive analytical concepts that Keynes developed in The General Theory. Demand and demand management have thereby come to represent one of the distinct trademarks of Keynesian macroeconomic theory and policy. It is not without reason that the central position of this concept has left the impression that Keynes’s macroeconomic model predominantly consists of theories for determining demand, while the supply side is neglected. From here it is a short step within a superficial interpretation to conclude that Keynes (and post-Keynesians) had ended up in a theoretical dead end, where macroeconomic development is exclusively determined by demand factors …

It is the behaviour of profit-seeking firms acting under the ontological condition of uncertainty that is at the centre of post-Keynesian concept of effective demand. Read more…

Keynes: a closet market monetarist?

Market monetarists like Scott Sumner totally focus on nominal GDP. And employment. Keynes, of course, totally did the same thing. Remember, by the way, that the accounting identities of the national accounts which are so crucial to the Keynesian system are only true when it comes to values in current prices! There are some differences, too, between market monetarists and Keynes, especial when it comes to expectations: are these fallible but influential or rational and inconsequential? Anyway, much of what Scott Sumner wrote sounds a lot like chapter 4 of the General Theory (sometimes even the style):

The three perplexities which most impeded my progress in writing this book, so that I could not express myself conveniently until I had found some solution for them, are: firstly, the choice of the units of quantity appropriate to the problems of the economic system as a whole; secondly, the part played by expectation in economic analysis; and, thirdly, the definition of income.

II

That the units, in terms of which economists commonly work, are unsatisfactory can be illustrated by the concepts of the National Dividend, the stock of real capital and the general price-level:—

(i) The National Dividend, as defined by Marshall and Professor Pigou, measures the volume of current output or real income and not the value of output or money-income. Read more…

Renewable energy in Europe

June 18, 2014 1 comment

In the European Union, production of renewable energy is increasing (graph 1, 2) and consumption of lignite and coal (CO2 wise the dirtiest of all fossil fuels because of a very high Carbon/Hydrogen content) is going down (graph 3,4), though especially in recent years not as fast as needed. Mind that actual use of solar energy is much higher than indicated by these graphs as ‘passive’ solar energy is not included. When the sun shines into our chambers in wintertime, we need less fossil fuels for heating. Despite this direct trade-off, this use of solar is not included in the data. Production of ‘renewable’ energy (see, for details, the Eurostat links) seems to be on an exponential growth path. Total use of energy however still has to decrease, in the near future, to enable long-term prosperity.
