This new model of international trade patterns is based on differing relative labor costs derived from differing endowments of skilled and unskilled labor, when labor is in elastic supply because of social support systems. All factors other than labor are assumed to be mobile across frontiers;...

We propose and solve a simple model of firm-level decisions to offshore production stages of lower skill intensity than that of activities that remain in the domestic location. In theory, offshoring is optimal only for the more productive among heterogeneous firms if it entails a fixed cost. In...

Gains from productivity and knowledge transmission arising from the presence of foreign firms has received a good deal of empirical attention, but micro-foundations for this mechanism are weak. Here we focus on production by foreign experts who may train domestic unskilled workers who work with...

This paper studies the role of wage and pension pressures in explaining the budget deficit crisis of 1991–2 after the remarkable 1990 Polish economic stabilization and liberalization. It also explains the persistence of the high tax wedge that later helped overcome the budget crisis. The...

The design of optimal immigration policy, particularly in the face of the spiraling demand for highly skilled workers, such as IT workers and engineers, is a topical issue in the policy debate as well as the economic literature. In this paper, we present empirical evidence from firm-level data...

This paper assesses the effects of applying VAT or a sales tax on (intermediate or final) sales of the financial sector. It uses a CGE Model calibrated for a small open economy. It highlights the differentiated sectoral and redistributional effects of these taxes and shows the importance of the...

Exchange rate regimes differ primarily by the activity of the exchange rate, not observable macroeconomic ‘fundamentals’. Fixed exchange rates are typically stable and floating exchange rates are volatile, but macro phenomena are regime-independent. Fundamentals only seem to be relevant for...

A common view in the literature is that the effect of energy price shocks on macroeconomic aggregates is asymmetric in energy price increases and decreases. We show that widely used asymmetric vector autoregressive models of the transmission of energy price shocks are misspecified, resulting in...

Business cycles reflect changes over time in the amount of trade between individuals. In this paper we show that incorporating explicitly intra-temporal gains from trade between individuals into a macroeconomic model can provide new insight into the potential mechanisms driving economic...

This paper develops a theory characterizing the effects of fiscal policy on unemployment over the business cycle. The theory is based on a model of equilibrium unemployment in which jobs are rationed in recessions. Fiscal policy in the form of government spending on public-sector jobs reduces...
