High-performance firms typically have two features in common: i) they produce in more than one country and ii) they produce more than one product. In this paper, we analyze the internationalization strategies of multi-product firms at the product-level. We find that the most productive firms...

I develop a dynamic version of the competitive search model with adverse selection in Guerrieri, Shimer and Wright (2010). My model allows for an analysis of the effects of firm learning on labor market efficiency in the presence of search frictions. I find that firm learning increases relative...

This paper analyses the effect of firm learning on labor market efficiency in a frictional labor market with asymmetric information. I consider a model with random matching and wage bargaining a la Pissarides (1985, 2000) where worker ability is unknown to firms at the hiring stage. Firm...

This paper uses census and survey data to identify the wage earning ability and the selection of recent Romanian migrants and returnees. We construct measures of selection across skill groups and estimate the average and the skill-specific premium for migration and return for three typical...

We determine workforce composition and wages in firms in the presence of productivity spill-overs between co-workers. In equilibrium, workers' wages depend on the production structure of firms, own group size, and aggregate workforce composition in the firm. We estimate the wage effects of...

The paper shows that immigration can create an incentive for deficit-spending among natives. If immigrants use up some given share of public funds net of debt service, a policy of running budget deficits becomes optimal. The optimal budget deficits are higher, the higher the share of net public...

We examine the effect of immigration on public spending from a theoretical (political economic) and an empirical perspective. We distinguish between public spending on private goods and on public goods. Our model implies that whether immigration increases or decreases public spending primarily...

We analyze the effect of workforce composition by birthplace on workers' wages. In our model, each worker's productivity may depend on whether co-workers are of the same or of a different birthplace. Wages depend both on the relative size of workers' groups as well as on the production structure...
