Agricultural price booms are better explained by common factors than by market-specific factors such as supply shocks. A capital asset pricing model-type model shows why one should expect this and Granger causality analysis establishes the role of demand growth, monetary expansion and exchange rate movements in explaining price movements over the period since 1971. The demand for grains and oilseeds as biofuel feedstocks has been cited as the main cause of the price rise, but there is little direct evidence for this contention. Instead, index-based investment in agricultural futures markets is seen as the major channel through which macroeconomic and monetary factors generated the 2007–2008 food price rises.

Subsidiary roles, vertical linkages and economic development: Lessons from transition economies

Recent tests for the convergence hypothesis derive from regressing average growth rates on initial levels: a negative initial coefficient is interpreted as convergence. These tests turn out to be plagued by Galton's classical fallacy of regression towards the mean. Using a dynamic version of Galton's fallacy, I establish that coefficients of arbitrary signs in such regressions are consistent with an unchanging cross-section distribution of incomes. Alternative, more direct empirics used here show a tendency for divergence, rather than convergence, of cross-country incomes.

Unemployment is still disappointingly high in most Central and East European countries, which may be a reflection of the ongoing adjustment to institutional shocks resulting from systemic transition, or may be caused by high labour market rigidity or aggregate demand that is too weak. This article investigates the dynamics of unemployment and output in those eight post-communist countries which entered the EU in 2004. We use a model related to Okun's Law; i.e. the first differences in unemployment rates are regressed on GDP growth rates. We estimate country and panel regressions with instrument variables (TSLS) and apply some tests to the data and regression results. We assume transition of labour markets to be accomplished when a robust relationship exists between unemployment rate changes and GDP growth. Moreover, the estimated coefficients contain information about labour market rigidity and unemployment thresholds of output growth. Our results suggest that the transition of labour markets can be regar...

The Relationship between Unemployment and Output in Post-communist Countries

The Euro Plus Pact was approved by 23 EU countries in March 2011. The Pact stipulates a range of quantitative targets meant to strengthen competitiveness and convergence with the ultimate aim of preventing the accumulation of unsustainable financial imbalances. This paper uses 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 data for 27 EU countries for the period 1995?2012. The main finding is that changes in the current account balance precedes changes in relative unit labour costs, while there is no discernable effect in the opposite direction. This suggests that the divergence in the unit labour cost between the countries in Northern Europe and countries in Southern and Central and Eastern Europe prior to the global financial crisis partly was the result of capital flows from the core of Europe to its periphery. The results also suggest that measures in the Euro Plus Pact to restrain unit labour costs may not have immediate effects on possible current account imbalances.

The Euro Plus Pact: Competitiveness and external capital flows in the EU countries

Trade between the European Union (EU) and the Transition Economies (TE) is increasingly characterised by intra-industry trade. The decomposition of intra-industry trade into horizontal and vertical shares reveals predominantly vertical structures with decisively more quality advantages for the EU and less quality advantages for TE countries whenever trade has been liberalised. Empirical research on factors determining this structure in an EU-TE framework lags behind theoretical and empirical research on horizontal and vertical trade in other regions of the world. The main objective of this paper is therefore to contribute to the ongoing debate on EU-TE trade structures by offering an explanation of vertical trade. We utilise a crosscountry approach in which relative wage differences, country size and income distribution play a leading role. We find first that relative differences in wages (per capita income) and country size explain intra-industry trade when trade is vertical and completely liberalised, and second that cross country differences in income distribution play no explanatory role. We conclude that EU firms have been able to increase their product quality and to shift lowquality segments to TE countries. This may suggest a product-quality cycle prevalent in EUTE trade.

The Euro Plus Pact was approved by the European Union countries in March 2011. The pact stipulates various measures to strengthen competitiveness with the ultimate aim of preventing accumulation of unsustainable external imbalances. This article uses Granger causality tests to assess the short-term linkages between changes in relative unit labour costs and changes in the current account balance for the period 1995–2011. The main finding is that changes in the current account balance precede changes in relative unit labour costs, while there is no discernible effect in the opposite direction. This suggests that capital flows from the European core to the periphery contributed to the divergence in unit labour costs across Europe prior to the global financial crisis. The results also suggest that the measures to restrain unit labour costs may have only limited effect on the current account balance in the short term.

The Euro Plus Pact: Competitiveness and External Capital Flows in the EU Countries

We argue that a "static" specification of the Maastricht criterion for long-term bond yields is not conducive to assessing stability of financial systems in euro-candidate countries. Instead, we advocate a dynamic approach to assessing interest rate convergence to a common currency that is based on the analysis of financial system stability. Accordingly, we empirically test volatility dynamics of the ten-year sovereign bond yields of the 2004 EU accession countries in relation to the eurozone yields during the January 2, 2001-January 22, 2009, sample period. Our results show a varied degree of the relationship between domestic and eurozone sovereign bond yields, the most pronounced for the Czech Republic, Slovenia, and Poland, and weaker for Hungary and Slovakia. We find some divergence of relative bond yields since the EU accession.
