This paper investigates the efficiency implications of two kinds of worker protection, namely job security and income protection. Both of them have important aggregate efficiency effects in the dynamic labour markets, where worker mobility is costly. In the absence of firing costs, income...

This paper studies implications of centralised wage setting for the level of taxation and public expenditure in an analytical model with unionised labour markets. We extend the previous studies by allowing for both demand and supply effects of labour. Also, in addition to the standard social...

This paper extends Svensson and Woodford’s (2003) partial information framework by allowing the private agents to achieve robustness against incomplete information about the structure of the economy by distorting their expectations in a particular direction. It shows how a linear rational...

This paper applies the robust control approach to a simple positive theory of monetary policy, when the central bank’s model of the economy is subject to misspecifications. It is shown that a central bank should react more aggressively to supply shocks when the model misspecifications grow...

In this study we provide a theoretical prediction of a complementary relationship between the incentive effects of product market competition and R&D subsidies using the theory of Aghion et. al (1997, 2001). The complementarity relationship and that of an inverted U-relationship is then tested...

This paper considers the effect of labour taxation on wages and employment in a trade union model with endogenous working hours. In the model, individuals choose working hours with a given wage rate, competitive firms decide on employment taking wages and working hours as given and a monopoly...

This paper analyses how collective bargaining affects the level and structure of labour and capital taxes in OECD countries by using cross-country-time-series data. Corporatist countries are found to have higher effective labor taxes on average during the 1970-1996 period. Effective capital...

This paper investigates the efficiency implications of two kinds of worker protection, job security and income protection. Both of them have important aggregate efficiency effects in the dynamic labor markets, where worker mobility is costly. In the absense of firing costs, income security has...

Monetary policy transmission lags create credibility problems for the inflation-targeting policy maker who acts under discretion. We show that if prices react to monetary policy with a longer lag than output, the welfare maximizing inflationtargeting policy implies no policy stabilization of...
