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...

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...

Governments typically used expenditures extensively as redistributive devices. Examples include the public provision of health, education, welfare, and public pensions. The purpose of this paper is to investigate the normative rationale for such policies. In particular, we study the role of...

Time inconsistency of tax policy is shown to arise in a setting in which households differ in their ability to accumulate wealth and the government has redistributional objectives. The government can levy non-distorting taxes but is precluded from redistributing optimally by a self-selection...

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...

This paper analyzes optimal employment and wage policies in the public sector in a model with endogenous involuntary unemployment. A public sector is introduced into models where shirking or turnover costs are present, and optimal wage and employment policies are derived. In both models, the...
