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 can achieve...

This paper examines regional population distribution when there is an interregional transfer policy without commitment. We introduce explicitly the following time structure of actions. Individuals make decisions on locational choices freely ex ante, but are immobile ex post. The interregional...

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...

Entrepreneurs starting new firms face two sorts of asymmetric information problems. Information about the quality of new investments may be private, leading to adverse selection in credit markets. And, entrepreneurs may not observe the quality of workers applying for jobs, resulting in adverse...

An overlapping generations models is constructed in which individual wealth is related to educational attainment, and in which liquidity constraints may induce children to invest in a sub-optimal level of education given their ability. Borrowing for educational attainment is obtained from within...

The Atkinson-Stiglitz Theorem states that if labor is weakly separable from goods in household utility functions, differential commodity taxation should not be not part of an optimal redistributive tax system. This Theorem, which is arguable the most policy-relevant result to come out of the...

The purpose of this paper is twofold. First, it extends previous models of non-cooperative private funding of pure public goods by allowing both for distortionary taxation of private goods and for subsidies based on contributions to the public goods. Second, it clarifies the type of behavioural...

We study the optimal redistributive tax structure when the population can be disaggregated into tagged groups. We begin with the case in which the tag has no normative significance, but simply separates the population into identifiable groups with different distributions of ability-types. Under...

This paper studies optimal linear income taxation and redistributive social insurance when the former has the traditional labor distortion and the latter generates both ex ante and ex post moral hazard. Private insurance is available and individuals differ in labor productivity and in loss...

Despite the fact that all developed economies levy broadly-based indirect taxes alongside direct taxes, little theory is devoted to explaining the direct-indirect tax mix. Our purpose is to show that if different taxes have different evasion characteristics, some optimal tax mix emerges...
