30/6/2014: The Euro Plus Pact: Getting Causality Between Current Account and Competitiveness Backwards


Gabrisch, Hubert and Staehr, Karsten, new paper published by ECB and titled "The Euro Plus Pact: Cost Competitiveness and External Capital Flows in the EU Countries" (February 18, 2014, ECB Working Paper No. 1650. http://ssrn.com/abstract=2397789) looks at the effectiveness of the Euro Plus Pact which was approved by 23 EU countries in March 2011 and came into force shortly afterwards.

Emphasis in bold in the quotes is mine.

"The Pact stipulates a range of quantitative targets meant to strengthen cost competitiveness with the aim of preventing the accumulation of external financial imbalances."

According to the authors: "The rationale behind the Euro Plus Pact is evident in its original name, the Competitiveness Pact, and also in its current subtitle: “Stronger economic policy coordination for competitiveness and convergence” (European Council 2011, p. 13)."

In virtual obsession of European policymakers with internal competitiveness expressed in terms of cost of labour and production, "Deteriorating cost or price competitiveness in individual countries is seen as a source of economic and financial instability. This view is directly stated in the conclusions from the European Council meeting at which the Euro Plus Pact was adopted (European Council 2011, p. 5): "The Euro Plus Pact […] will further strengthen the economic pillar of EMU and achieve a new quality of policy coordination, with the objective of improving competitiveness and thereby leading to a higher degree of convergence […].""

The authors use Granger causality tests and vector autoregressive models "to assess the short-term linkages between changes in the relative unit labour cost and changes in the current account balance. The sample consists of annual data for 27 EU countries for the period 1995-2012." This allows them to explore the direction and size of the short term linkages between cost or price competitiveness and external capital flows in the EU countries.

"The analyses are particularly pertinent given the adoption of the Euro Plus Pact… The underlying rationale is that deteriorating cost competitiveness is an important factor behind the accumulation of current account deficits and financial vulnerabilities." Thus, the "participating countries must take measures to improve their cost or price competitiveness and thereby reduce the likelihood of financial imbalances accumulating."

First, authors use Granger causality tests to determine "whether lagged values of one variable help explain the other variable when autocorrelation and country fixed effects are taken into account." The result is: lagged changes in the current account balance help explain changes in unit labour costs, while there is no effect in the opposite direction. The results hold for all 27 EU countries, for the EU15 countries and for 10 EU countries.

Second, vector autoregressive models confirmed "qualitative results are in all cases very similar to those of the Granger causality tests. …"

In other words, "changes in capital flows appear to affect cost competitiveness in the short term, while changes in competitiveness appear to have no effect on capital flows in the short term." This is important, as many policy analysts (e.g. Bruegel) and European policymakers (from Commission to national governments) routinely express the view that external imbalances are the result of poor competitiveness, especially in the periphery and especially in the context of driving the momentum of the financial crisis and the great Recession.

Here is what the authors have to say on this: "Increasing capital flows from the core to the periphery of Europe may partly explain the deteriorating cost competitiveness in many countries in Southern and Central and Eastern Europe as well as the improving cost competitiveness in many countries in Northern Europe [prior to the Crisis]. The reversal of these capital flows after the outbreak of the global financial crisis may lead to ensuring changes in cost competitiveness."

But more crucially, there seems to be no reverse direction of causality: pursuit of greater competitiveness does not seem to be a correct prescription for achieving external balances. "...the measures in the Euro Plus Pact to restrain the growth of unit labour costs may not affect the current account balance in the short term."

Now, wait, that is ECB research paper that says 'restraining growth in unit labour costs' (aka: improving competitiveness) may not do much for external balances… Hmm… did anyone hear that Euro Plus Pact tree fall?

And moving beyond the past: is anyone monitoring flows of 'capital' to the 'periphery' in the form of extremely depressed Government debt yields that are prevailing today? Cause you know, that competitiveness might be falling next time we look…

29/6/2014: Tech & Science Migrants & Native Workers: US Evidence


Tech specialists and ICT specialists hired from abroad into countries like Ireland are seen, by the policymakers, as a necessary and sufficient evidence of growth in employment and domestic economic well-being. The reason for this is often found the argument that lack of local skills will result in higher labour costs and lower competitiveness of the sector and, thus, lead to outflow of ICT-linked FDI and reduced MNCs activity in the economy.

Part of this rationale is correct. Part is wrong. I recently posited, in my Sunday Times ex-column and in a WSJ op-ed, the thesis that in Ireland's case, tax optimisation by ICT MNCs is equivalent to a resource curse, whereby excessive amounts of financial resources flows into attracting and retaining skilled workers, resulting in underinvestment in other sectors of economy. Beyond this, the Government, grown accustomed to windfall revenues from the tax optimising MNCs has lower incentives to focus on developing indigenous and highly competitive specialisation.

Setting aside these more complex arguments, what is the effect of the skilled ICT and tech and R&D workers immigration on domestic economy?

Peri, Giovanni and Shih, Kevin Yang and Sparber, Chad, in their recent paper titled "Foreign Stem Workers and Native Wages and Employment in U.S. Cities" (May 2014, NBER Working Paper No. w20093) looked at the effects of the Scientists, Technology professionals, Engineers, and Mathematicians (STEM workers) immigration into the US. Per authors, STEM workers "are fundamental inputs in scientific innovation and technological adoption, the main drivers of productivity growth in the U.S."

In their paper, the authors attempt to "identify the effect of STEM worker growth on the wages and employment of college and non-college educated native workers in 219 U.S. cities from 1990 to 2010. In order to identify a supply-driven and heterogeneous increase in STEM workers across U.S. cities, we use the distribution of foreign-born STEM workers in 1980 and exploit the introduction and variation of the H-1B visa program granting entry to foreign-born college educated (mainly STEM) workers."

Key findings:

  • "We find that H-1B-driven increases in STEM workers in a city were associated with significant increases in wages paid to college educated natives." In other words, shortages of specialist skills (signified by intensity of inflow of STEM migrants) do bid up wages for similarly-educated (in degree attainment and also in skills similarities) natives. This agrees with my argument that far from driving down labour costs for skilled workers not just in STEM-related sectors, but across all educated workforce, STEM-targeted immigration is associated with higher labour costs. Often, this is seen as being driven by complementarity between STEM skills and related services professionals (legals, accounting, sales, marketing, etc). But is that the case of signalling value of their degrees going up in the market, or is it the case of their skills value going up? One way or the other, more STEM immigrants seems to do nothing to improve labour costs competitiveness.
  • "Wage increases for non-college educated natives are smaller but still significant." So wage inflation is not moderated by STEM migration, even if we control for skills. In other words, all sectors of city economy are facing rising costs in the presence of STEM immigration. This, of course, is not an argument of causality, but it is also not the evidence that would be consistent with an argument that STEM immigration induces gains in labour competitiveness.
  • "We do not find significant effects on employment." In other words, jobs creation is not what happens when you open up targeted skills-driven migration. And, by converse, it is not impacted by restricting it. Which begs a question: every month Irish ministers present jobs announcements by STEM-intensive ICT services companies as evidence of employment creation. Every time they do so, they omit consideration of what higher cost of skilled and unskilled workers is doing to the rest of the economy. Should they be concerned with the latter at least as much as with the former? The study evidence suggests they should.
  • "We also find that STEM workers increased housing rents for college graduates, which eroded part of their wage gains." Ah, can that be a reason why rents are inflating in Dublin, especially in the areas where STEM-equivalent skills are at the highest premium (IFSC and South Docklands corridor)? In summary, therefore, higher employment and immigration of STEM workers seems to be associated with higher costs of living for all workers. Is it correct to posit a question of spillovers or externalities that arise from greater share of new employment going to skilled ICT immigrants onto the long term residents of the country or city? If yes, then the logic suggests that there should be consideration of transfers from the immigrants under STEM programme to at least those natives and long term residents who do not gain in wages enough to compensate them for the rising cost of living.

Overall, authors conclude that "Together, these results imply a significant effect of foreign STEM on total factor productivity growth in the average US city between 1990 and 2010." Which is, of course, good. But it does not tell us if this TFP growth actually spreads across the entire economy or stays within STEM-intensive sectors. We do not know if TFP gains in STEM sectors are not offset by labour competitiveness losses in the rest of the host economy. And, crucially, it does not tell us if the above questions, posited in the bullet point comments, can be answered unambiguously in favour of more STEM-linked immigration.

29/6/2014: What a Difference a Year of ECB Activism Makes...


Mapping decline in CDS and implied probabilities of default for Euro area 'peripherals' over the last 12 months:

Largest declines: Greece, followed by Portugal, Spain, Italy and lastly Ireland. Timing of declines and divergent macrofundamentals of these countries suggest that drop in CDS has little to do with internal policies and performance of individual states - the 'periphery' is still being priced jointly. The decline in risk assessments of the 'peripherals' is primarily down to common policy, aka: the ECB.

On the other hand, if we are to distinguish within the 'peripherals', we can identify 3 sub-groups of countries:

  • Weakest and stand-alone: Greece
  • Mid-range weakness, also stand-alone: Portugal
  • Stronger 'peripherals': Ireland, Spain and Italy

29/6/2014: Mid-Summer CDS Dreams: Ukraine v Russia


One of these countries has a brand new Association Agreement with the EU... and a fresh probability of sovereign default of 41%... another one (with probability of default at 11.9%) does not...


In two years from June 2012 through June 2014, Ukraine's probability of default declined 1.47% as the country received massive injections of funds from the IMF, US and EU. Russia's probability of default fell 3.89% over the same time. For comparatives: Ukraine's June probability of default is running at around 41%, Serbia's at 17.6%. Ukraine is currently the worst rated sovereign (by CDS-based probability of default) of any state with an Association Agreement with EU.

29/6/2014: London Property Markets: A Safe Haven After All


A fascinatingly interesting study looking into London property markets from the point of view of safe haven properties. Badarinza, Cristian and Ramadorai, Tarun, "Preferred Habitats and Safe-Haven Effects: Evidence from the London Housing Market" (April 17, 2014, http://ssrn.com/abstract=2353124) uses "a new cross-sectional approach, motivated by the insight that investors may have different "preferred habitats" within a broad asset class."

The study deploys this strategy "on large databases of historical housing transactions in London, finding that economic and political risk in Southern Europe, China, the Middle East, Russia, and South Asia helps explain price and volume dynamics in the London housing market over the past two decades. Safe-haven effects on the London housing market are long-lasting and significant, but temporary. The method also uncovers intriguing insights about cross-country variation in preferred habitats within London."


28/6/2014: Who are the Joneses?


Dahlin, Maria Björnsdotter and Kapteyn, Arie and Tassot, Caroline paper "Who are the Joneses?" (June 2014. CESR-Schaeffer Working Paper No. 2014-004. http://ssrn.com/abstract=2450266) attempts to answer a very important question in economics of individual perceptions and referencing of own well-being relative to well-being of others. The study tackles an issue that forms the core of a number of macroeconomic models, but also of relevance to the active debate about relative poverty and relative incomes.

"A burgeoning literature investigates the extent to which self-reported well-being (or happiness) or satisfaction with income is negatively related to the income of others" or the Joneses. "In many of the empirical studies, the assumption is that the incomes that matter are those of other individuals or households in the same geographical area." In other words - physical proximity is of the matter.

"In an experiment conducted in the American Life Panel, we elicit the strength of comparison with different groups, including neighbors, individuals of similar age and coworkers."

Fascinating findings emerged:

  1. "Individuals are much more likely to compare their income to the incomes of their family and friends, their coworkers and people their age than to people living in the same street, town, in the US, or in the world." In other words, we reference our own well-being against well-being of those close to us socially and family-wise, not those who physically live near us, but are strangers to us. A relatively rich uncle may be inducing greater dissatisfaction onto us, than a filthy rich neighbour. In which case, were relative poverty be a concern, taxing family members on higher incomes is better than taxing everyone on higher incomes. Which, of course, would be an absurd policy.
  2. "…we find both at the zip code and at the PUMA geographic level that own income or rank in the local income distribution matter for happiness and satisfaction with income, but incomes in the same geographic region do not influence own happiness when controlling for own income."  
  3. "When asking respondents directly for how they rate the position of own and others’ income we find that higher estimates of neighbors’ income are negatively related with satisfaction with own income. Additionally, respondents who compare more intensively with their neighbors perceive the difference between their own income and that of their neighbors to be larger." So we do rate strangers' income relative to our own. Just not as much as we rate relatives' and friends' income relative to our own.
  4. "Using age-based reference groups instead of geography-based reference groups, we find a consistent negative effect of the log median income and the perceived income in an individuals’ age group". In other words, the Joneses that we 'benchmark' ourselves against are more likely to be those from similar/shared cohort, in this case - cohort by age. The old do not begrudge, as much, the young, but they do begrudge other old.

"Overall, these results indicate that comparisons with neighbors may not be the most important channel through which perception of others’ income impacts one’s own well-being."

In other words, relative benchmarking matters, but it strength varies with familial and social ties, and matters less in terms of proximity. As I noted, half-jokingly, above: a richer uncle induces more negative referencing even if he lives in a distant community, than a richer neighbour who flaunts her/his wealth in our face.

28/6/2014: Public Debt: It Really Is the Case of Beggar Thy Children…


In a new paper, researchers from Germany use "controlled laboratory experiment with and without overlapping generations to study the emergence of public debt."

The set up of the experiment is simple: "Public debt is chosen by popular vote, pays for public goods, and is repaid with general taxes."

The end result is asymmetric:

  • "With a single generation, public debt is accumulated prudently, never leading to over-indebtedness." In other words, if your generation is the one responsible for repaying debt, spending is prudent and debt accumulation is ex ante bounded by expected income.
  • However, "with multiple generations, public debt is accumulated rapidly as soon as the burden of debt and the risk of over-indebtedness can be shifted to future generations."

Crucially, "debt ceiling mechanisms do not mitigate the debt problem. With overlapping generations, political debt cycles emerge, oscillating with the age of the majority of voters." In other words, the idea that debt can be controlled by explicit limits is useless. So much is clear from the US debt ceiling system performance, as well as from the EU SGP experiences. And as much will be confirmed by the Fiscal Compact rules application in due time. Worse, absent levels constraints we are left with the Keynesian proviso that simply says: Be nice. Save when you can, send when you need. Oops... if the stick does not work, any hope the carrot will? I don't think so...

The paper was written by Fochmann, Martin and Sadrieh, Abdolkarim and Weimann, Joachim, and is titled "Understanding the Emergence of Public Debt" (May 24, 2014, CESifo Working Paper Series No. 4820. http://ssrn.com/abstract=2458325).

28/6/2014: Exports and Pollution Intensity: Swedish Evidence


A new paper published by CESIfo attempts to understand what mechanisms lead to the empirically-observed negative relationship between harmful CO2 emissions by firms and firm's exports.

Forslid, Rikard and Okubo, Toshihiro and Ulltveit-Moe, Karen Helene paper titled "Why are Firms that Export Cleaner? International Trade and CO2 Emissions" (May 24, 2014, CESifo Working Paper Series No. 4817. http://ssrn.com/abstract=2458293 "…develops a model of trade and CO2 emissions with heterogenous firms, where firms make abatement investments and thereby have an impact on their level of emissions."

Theoretical model "shows that investments in abatements are positively related to firm productivity and firm exports. Emission intensity is, however, negatively related to firms' productivity and exports. The basic reason for these results is that a larger production scale supports more investments in abatement and, in turn, lower emissions per output."

The authors then show that "the overall effect of trade is to reduce emissions. Trade weeds out some of the least productive and dirtiest firms thereby shifting production away from relatively dirty low productive local firms to more productive and cleaner exporters. The overall effect of trade is therefore to reduce emissions."

Lastly, the authors "test empirical implications of the model using unique Swedish firm-level data. The empirical results support our model."

28/6/2014: WLASze: Weekend Links on Arts, Sciences & zero economics


It has been some time since I did my WLASze (Weekend Links on Arts, Sciences and zero economics) last. The reason being somewhat strange state of mind as of late: less calm, less retrospection, more rushed work… the usual.

Here are couple interesting links that I cam across this week.

28/6/2014: Irish Retail Sales: Q2 data to-date confirms fragile recovery


In the previous post I covered detailed analysis of Core Retail Sales data for May 2014: here. Now, a quick look at Q2 averages (for 2014 we have average over April and May) for the period from 2005 through latest.

Take a look at the chart plotting declines (as of April-May average) in retail sales activity compared to peak for Q2 data:


This data shows the following:

  1. The only two sub-categories of goods and services where retail sales indices in Value terms are in shallower decline than in Volume terms (in other words inflation is positive and feeding through to consumers) are: Automotive Fuel and Bars - in other words two sectors where prices for inputs are largely controlled/set by the state.
  2. No category has recovered pre-crisis levels of retail sales by both value and volume, while only one category (Food) recovered sales in volume, relative to pre-crisis activity.
This puts into perspective the extent to which the recovery we are experiencing so far is fragile.
