Customary rules governing access to land and other natural resources in village societies have characteristics that allow them to fulfil social security functions and achieve equity objectives. This is true of both common-property resources and land parcels held under individualized tenure....

Increasingly, immigration policies tend to favour the entry of skilled workers, raising substantial concerns among sending countries. The ‘revisionist’ approach to the analysis of the brain drain holds that such concerns are largely unwarranted. First, sustained migratory flows may be...

Building on recent work in the fiscal response literature, the present paper develops a new fiscal response model, which, for the first time in the relevant literature, combines the ideas of both endogenous and disaggregated aid. We endogenized aid on the grounds that the recipient government...

This paper constructs a macroeconomic model of North-South interaction where the flow of narcotics from the South to the North is restricted. Their economic effects are akin to quantitative restrictions in trade policy. Two alternative policy scenarios will be considered. One involves reducing...

Of the 41 HIPCs, 11 are classified by the IMF and World Bank as conflict-affected. Can debt relief reduce the level of violent conflict in these countries? By providing additional resources to finance broad-based public spending, debt relief could help to redress the grievances that contribute...

The standard method of testing for efficient risk-sharing in village economies does not allow one to identify vulnerable households, only to make statements about the average risk in the village, or of sub-groups identifiable on the basis of observables. Here, by working directly with...

This paper explores pitfalls in regression-based inequality decompositions. A simple procedure is developed for rectifying these pitfalls. The procedure does not impose any restrictions on the underlying regression model and it can be applied to any inequality measure(s). Once combined with...

We consider extortion gangs that are mafia-like in their protection of targets, but that are unlike the Mafia in their competition over targets. Does this type of organized crime pay? How are the returns to extortion affected by the number of competing extortionists and the violence they apply?...

A simple two-stage game-theoretic model of conflict is analysed, where the government can send raiders for terrorising the population to flee before the fighting proper begins. The resulting displacement of population reduces the efficiency of the guerrilla in the fight against the government....

How much does economic growth contribute to poverty reduction? I discuss analytical and empirical approches to assess the poverty elasticity of growth, and emphasize that the relationship between growth and poverty change is non-constant. For a given poverty measure, it depends on initial...
