This paper considers the effects of trade policy-tariffs and quotas-when importing is done by competitive traders who are identical ex ante but differ ex post. We show that the standard equivalence results no longer hold and the conventional ranking of tariffs and quotas is turned on its head:...

During the transition process, many existing social sector institutions and policies were significantly eroded and their underlying character changed. As a result, they often do not redistribute to the poorest, nor generally serve the role of facilitating economic change. Social sector reforms...

Tax laws and administrations often treat different size firms differently. There is, however, little research on the consequences. As modeled here, oligopolists with different efficiencies determine the size distribution of firms. A government that maximizes a weighted sum of consumer surplus,...

Using a simple model of two-sided markets, we show that, in the social optimum, platform pricing leads to an inherent cost recovery problem. This result is driven by the positive externality of participation that users on either side of the market exert on the opposite side. The contribution of...

Using urban household surveys, we constructed a panel dataset to study the effects of the Argentine macroeconomic crisis of 1999-2002 with the aim of (1) identifying the most vulnerable households, (2) investigating whether employment in the public sector and government spending served to...

This paper uses a partial equilibrium framework to evaluate the relative efficiency, distributional and revenue implications of rice tariffs and targeted transfers in Madagascar, especially in the context of identifying their respective roles for poverty alleviation. Although there are likely to...

As in other sectors, competition in finance matters for allocative, productive and dynamic efficiency. Theory suggests, however, that unfettered competition is not first best given the special features of finance. I review these analytics and describe how to assess the degree of competition in...

The paper presents numerical simulations of various fiscal rules for oil-producing countries. Welfare implications are sensitive to the choice of the social welfare function, initial conditions, and non-oil growth prospects. The distribution of non-oil wealth is important for countries with...

Lucas (2004) asserts that "Of the tendencies that are harmful to sound economics, the most seductive, and in my opinion the most poisonous, is to focus on questions of distribution... The potential for improving the lives of poor people by finding different ways of distributing current...

Growth is pro-poor if the poverty measure of interest falls. This implies three potential sources of pro-poor growth: (a) a high rate of growth of average incomes; (b) a high sensitivity of poverty to growth in average incomes; and (c) a poverty-reducing pattern of growth in relative incomes. I...
