Does emigration really drain human capital accumulation in origin countries? This paper explores a unique household survey designed and conducted to answer this specific question for the case of Cape Verde - the sub-Saharan African country with the largest fraction of tertiary-educated...

Joining the EU is a natural experiment that drastically opens the borders of richer European countries to immigration.  However, migration flows from southern Europe responded little to  free migration after 1986, despite substantial differentials in real GDP per worker.  The simple...

We provide cogent evidence for the causal pro-trade effect of migrants and in doing so establish an important link between migrant networks and long-run economic development.  To this end, we exploit a unique event in human history, the exodus of the Vietnamese Boat People to the US.  This...

This paper evaluates whether immigration can mitigate the Dutch disease effects associated with booms in natural resource sectors.  We derive predicted changes in the size of the non-tradable sector from a small general-equilibrium model a la Obstfeld-Rogoff.  Using data for Canadian...

This paper uses firm-level data to address the following issues; (i) Have wage differentials increased at the level of the firm? (ii) Are they any patterns in the levels and changes of these differentials? (iii) Do the same factors determine the pay of both low-skilled and high-skilled workers?

In this paper we examine how the quantity of information generated about firm prospects can be improved by splitting a firm’s cash flow into a ‘safe’ claim (debt) and a ‘risky’ claim (equity). The former, being relatively...

Donors who try to impose policy conditionality on countries receiving their aid commonly face confflicting incentives between using aid to induce income-increasing reforms and using aid to assist low-income countries: this confflict can lead to a time-consistency problem. This paper o¤ers a...

This paper shows how to derive a complete set of optimality conditions characterising the solution to a dynamic optimal income tax problem in the spirit of Mirrlees (1971), under the assumption that a 'first-order' approach to incentive compatibility is valid.  The method relies on constructing...

This paper analyses collusion-proof multilateral insurance contracts between a risk neutral insurer and multiple risk averse agents in an environment of asymmetric costly state verification.  Optimal contracts involve the group of agents pooling uncertainty and the insurer acting as reinsurer...

This chapter reviews the literature on the theory of relational incentive contracts.  It motivates the discussion by the classic applications of relational contracts to the GM-Fisher Body relationship and the relationships between Japanese automobile manufacturers and their subcontractors.  It...
