It is widely perceived that globalization is a threat to tax financed public sector activities. The argument is that public activities (public consumption and transfers) financed by income taxes may distort labour markets and cause higher wages and thus a loss of competitiveness. If the...

This paper takes a first step in analysing how a monetary union performs in the presence of labour market asymmetries. Differences in wage flexibility, market power and country sizes are allowed for in a setting with both country-specific and aggregate shocks. The implications of asymmetries for...

In a two-country model with trade driven by comparative advantages, it is considered how imperfectly competitive labour markets are affected by lower frictions in international goods trade. Easier goods trading is equivalent to increased mobility of employment across countries and thus a change...

Recently work by Pesaran (2006) has suggested a method which makes use of cross-sectional averages to provide valid inference for stationary panel regressions with multifactor error...

The consequences of cylical contingencies in unemployment insurance systems are considered in a search-matching model allowing for shifts between "good" and "bad" states of nature. An argument for state contingencies is that insurance arguments are stronger and incentive effects weaker in bad...
