British Balance of Competence Reviews, Part II: Again, a huge contradiction between the evidence and Eurosceptic populism. EPIN Paper No. 40, June 2014

This paper is the second in a series for a CEPS project entitled “The British Question and the Search for a Fresh European Narrative”. It is pegged on an ambitious exercise by the British government to review all the competences of the European Union on the basis of evidence submitted by independent stakeholders. In all, 32 sectoral policy reviews are being produced over the period 2013-2015, as input into public information and debate leading up to a referendum on whether the UK should remain in, or secede from, the EU, planned for 2017. This second set of reviews covers a broad range of EU policies (for the single market for goods, external trade, transport policy, environment, climate change, research, asylum, non-EU immigration, civil judicial cooperation, tourism, culture and sport). The findings confirm what emerged from the first set of reviews, namely that there is little or no case for repatriation of EU competences at the level they are defined in the treaties. This does not exclude that at a more detailed level there can be individual actions or laws that might be done better or not at all. However, that is the task of all the institutions to work at on a regular basis, and hardly a rationale for secession. For the UK in particular the EU has shown considerable flexibility in agreeing to special arrangements, such as in the case of the policies here reviewed of asylum, non-EU immigration and civil judicial cooperation. In other areas reviewed here, such as the single market for goods, external trade, transport, environment, climate change and research, there is a good fit between the EU’s policies and UK priorities, with the EU perceived by stakeholders as an ‘amplifier’ of British interests.

The Theoretical Framework and Methodology to Estimate the Farm Labour and Other Factor-Derived Demand and Output Supply Systems. Factor Markets Working Document No. 44, May 2013

This paper provides a conceptual framework for the estimation of the farm labour and other factor-derived demand and output supply systems. In order to analyse the drivers of labour demand in agriculture and account for the impact of policies on those decisions, it is necessary to acknowledge the interaction between the different factor markets. For this purpose, we present a review of the theoretical background to primal and dual representations of production and some empirical literature that has made use of derived demand systems. The main focus of the empirical work is to study the effect of market distortions in one market, through inefficient pricing, on the demand for other inputs. Therefore, own-price and cross-price elasticities of demand become key variables in the analysis. The dual cost function is selected as the most appropriate approach, where input prices are assumed to be exogenous. A commonly employed specification – and one that is particularly convenient due to its flexible form – is the translog cost function. The analysis consists of estimating the system of cost-share equations, in order to obtain the derived demand functions for inputs. Thus, the elasticities of factor substitution can be used to examine the complementarity/substitutability between inputs.

Effectiveness and transmission of the ECB’s balance sheet policies. National Bank of Belgium Working Paper No. 275, December 2014

We estimate the effects of exogenous innovations to the balance sheet of the ECB since the start of the financial crisis within a structural VAR framework. An expansionary balance sheet shock stimulates bank lending, stabilizes financial markets, and has a positive impact on economic activity and prices. The effects on bank lending and output turn out to be smaller in the member countries that have been more affected by the financial crisis, in particular those countries where the banking system is less well-capitalized.

Filling the gap: open economy considerations for more reliable potential output estimates. Bruegel Working Paper 2015/11, October 2015

This paper argues that the Phillips curve relationship is not sufficient to trace back the output gap, because the effect of excess demand is not symmetric across tradeable and non-tradeable sectors. In the non-tradeable sector, excess demand creates excess employment and inflation via the Phillips curve, while in the tradeable sector much of the excess demand is absorbed by the trade balance. We set up an unobserved-components model including both a Phillips curve and a current account equation to estimate ‘sustainable output’ for 45 countries. Our estimates for many countries differ substantially from the potential output estimates of the European Commission, IMF and OECD. We assemble a comprehensive real-time dataset to estimate our model on data which was available in each year from 2004-15. Our model was able to identify correctly the sign of pre-crisis output gaps using real time data for countries such as the United States, Spain and Ireland, in contrast to the estimates of the three institutions, which estimated negative output gaps real-time, while their current estimates for the pre-crisis period suggest positive gaps. In the past five years the annual output gap estimate revisions of our model, the European Commission, IMF, OECD and the Hodrick-Prescott filter were broadly similar in the range of 0.5-1.0 percent of GDP for advanced countries. Such large revisions are worrisome, because the European fiscal framework can translate the imprecision in output gap estimates into poorly grounded fiscal policymaking in the EU.
