Redistribution programs are constrained because those not working may be either unable to work, voluntarily unemployed or involuntarily unemployed. The inability to distinguish among these theree cases inhibits the targeting of transfers to those most in need. Enabling the government to monitor...

We study the features of optimal transfers to the non-employed which include those unable to work, the voluntarily unemployed, and the involuntarily unemployed. Both voluntary and involuntary unemployment are endogenous. We analyze optimal government policies in the presence of two types of...

An optimal commodity tax approach is taken to compare trade taxes and VATs when some commodities are produced informally. Trade taxes apply to all imports and exports, including intermediate goods, while the VAT applies only to sales by the formal sector and imports. The VAT achieves production...

This paper uses a sequence of models to study the efficiency of credit-market equilibria, and the scope for welfare-improving policy interventions, when financial intermediaries cannot observe the riskiness or returns of potential investment projects by new firms. It is first shown that when...

This paper examines how sequential decision-making by two levels of government can result in vertical fiscal imbalances (VFI). Federal-regional transfers serve to equalize the marginal cost of public funds between regions hit by different shocks. The optimal vertical fiscal gap minimizes the...

Politicians typically do not know what policies are best for achieving their broad objectives, so rely on bureaucrats for advice. Bureaucrats are better informed, so can manipulate outcomes by proposing policies that suit their interests. We capture this conflict of interests using a model of...

We examine how three sources of asymmetric information affect the supply of entrepreneurs and unemployment. In the first case, banks cannot observe entrepreneurs' risk of failure so ration credit. This increases the number of entrepreneurs and the level of unemployment. In the second case, firms...

The Canadian system of equalization is designed to address differences in revenue-raising capacity across provinces, basing a province's entitlements on its actual tax bases. However, since it does so on a year-on-year basis, the standard against which a given province's equalization...

We study the efficiency of credit market equilibria when financial intermediaries cannot observe the riskiness or the returns of potential investment projects. With loan financing, there is over-investment in high-return, high-risk projects and under-investment in low-return, low-risk projects...
