Labour Market Institutions and Labour Market Performance: A Survey of the Literature

This paper presents a selective survey of the recent literature on labour market institutions. It describes the different empirical approaches used to explore the nexus between labour market institutions and labour market performance. It stresses that the effect of institutions is complex in both stock and flow models and that it is also crucial to take into account the interactions they generate among themselves and with macroeconomic shocks. While their importance in explaining labour market performances is uncontroversial, there is no full consensus on their actual impact and the precise transmission channels. In addition, rather than taking institutions for granted, a new branch of research attempts to understand them as the result of an endogenous process. The paper also briefly discusses the relationships between the efficiency of the redistributive policies (via taxation) and the type of protection provided (on the job or in the market). Lastly, the paper examines the key issue of efficient policy design both at the macro- and micro-level.

Government Expenditure and Economic Growth in the EU: Long-Run Tendencies and Short-Term Adjustment

This paper analyses both the long and the short-run relation between government expenditure and potential output in EU countries by means of pooled mean group estimation (Pesaran, Shin, and Smith (1999)). Results show that, over a sample comprising EU-15 countries over the 1970-2003 period, it cannot be rejected the hypothesis of a common long-term elasticity between cyclically-adjusted primary expenditure and potential output close to unity. However, the long-run elasticity decreased considerably over the decades and is significantly higher than unity in catching-up countries, in fast-ageing countries, in low-debt countries, and in countries with weak numerical rules for the control of government spending. The average speed of adjustment of government expenditure to its long-tem relation is 3 years, but there are significant differences across countries. Anglo-Saxon and Nordic countries exhibit in general a faster adjustment process, while adjustment in Southern European countries appears somehow slower.

Institutions and Performance in European Labour Markets: Taking a Fresh Look at Evidence

This paper presents a selective survey of the recent literature on labour market institutions and performance and offers new empirical EU-based evidence on the impact of labour market reforms on employment and labour market adjustment. While the literature traditionally treats labour market institutions as exogenous, attention shifted recently towards understanding the underlying causes of specific institutional arrangements. As a consequence, the literature highlights the great importance of an efficient policy design exploiting these interactions wisely and identifies general principles for achieving an efficient policy design at both macro and micro levels. While empirical evidence does no show a major change in terms of intensity of labour market reform after the setting of the Economic and Monetary Union and the creation of the euro, the reforms aiming at strengthening the labour market attachment of vulnerable groups tend to have been successful both in raising their employment and increasing labour market adjustment.

Do Labour Taxes (and Their Composition) Affect Wages in the Short and the Long Run

Measures aimed at reducing the tax burden on labour have been advocated to alleviate the EU unemployment problem. Most of the analyses document a relationship between the unemployment rate and the tax burden on labour. Hence, it is not possible to discern whether the effect on unemployment derives from labour demand, labour supply or trough the wage formation mechanism. Moreover, the empirical analyses are usually static, and may be indicative of the steady-state determinants of the unemployment rate and do not reveal the features of the adjustment process. This paper studies the relationship between labour taxes and labour costs by modelling the wage formation mechanism in a dynamic context. We test if the composition of labour taxes affects labour costs in the short- and in the long-run and whether highly centralised bargaining systems have better employment performance than decentralised ones. We apply static and dynamic panel data techniques to a panel of EU countries.
