We study the optimal anticipated monetary policy in a flexible-price economy featuring heterogenous agents and incomplete markets, which give rise to a business cycle. In this setting money policy has distributional effects that depend on the state of the cycle. We parsimoniously characterize...

The paper evaluates the potential gains from labour immigration for the European Union. After a review of the East-West migration problem and recent western migration policies, governmentally controlled labour immigration is studied in a framework with unions, unemployment and heterogenous...

The ‘fractal’ nature of the rise in earnings dispersion is one of its key features and remains a puzzle. This paper offers a new perspective on the causes of changes in earnings dispersion, focusing on the role of labour reallocation. Once we drop the assumption that all firms pay a given...

We introduce firm and worker heterogeneity into a model of innovation-driven endogenous growth. Individuals who differ in ability sort into either a research sector or a manufacturing sector that produces differentiated goods. Each research project generates a new variety of the differentiated...

This paper analyses capital export controls under majority voting. It is shown that individuals vote according to their factor endowment ratio. An individual’s optimal restriction is tighter, the lower their capital-labour ratio and the larger the country; it is also tighter if unemployment...

Switzerland has experienced a substantial influx of immigrants over the 50 years since World War II, to the extent that it now has one of the highest share of foreigners in population among OECD countries. This paper analyses Switzerland’s experience of migration, centring on two main issues:...

Economists tend to agree that international trade liberalization brings significant gains from trade to countries engaging in such a process. At the same time however, public opinion is much less optimistic and there is a widespread concern that the current sharing of the gains from trade is...

This paper employs a multi-country large scale Overlapping Generations model with uninsurable labour productivity and mortality risk to quantify the impact of the demographic transition towards an older population in industrialized countries on world-wide rates of return, international capital...

We develop an equilibrium search-matching model with risk-neutral agents and two-sided ex-ante heterogeneity. Unemployment insurance has the standard effect of reducing employment, but also helps workers to get a suitable job. The predictions of our simple model are consistent with the...

Mobility of workers involves flows of labour, human capital and other production factors and thus contributes to a more efficient allocation of resources. Besides these effects on allocative efficiency, migrant flows affect relative wages and also change the international and national...
