This paper surveys the various forms of market failure that can arise when innovating entrepreneurs consider entering an industry, and outlines possible implications for public policy. Externalities can arise from entrepreneurial activities such as spillover benefits from new innovations and...

Tax evasion is modeled as a risky activity and integrated into a standard problem of optimal tax design. It is shown that there is a trade off between reducing tax evasion and reducing tax distortion. Thus it is efficient to supplement a broad-based wage tax by a tax on specific consumption if...

This paper examines the question of achieving a societal consensus around redistributive policies. Its extent is measured by the degree of work participation among the different skill classes that populate the economy. This consensus is driven both by the material incentives and heterogeneous...

This paper analyzes optimal linear commodity taxes joint with non-linear income taxes. We provide optimal tax rules based on empirically observable elasticities. We demonstrate that commodities should be taxed/subsidized if doing so boosts labor supply. The critical role of commodity taxation is...

A fundamental issues in designing any fiscal regime for non-renewable resources is the balance between rent taxes and royalties. This paper reviews the core issues that arise, in terms of both efficient rent extraction and correcting various market failures. Issues of asymmetric information, for...

We study optimal nonlinear income taxation when earnings can differ because of both ability and luck, so the income tax has both a redistributive role and an insurance role. A substantial literature on optimal redistribution in the absence of uncertainty has evolved since Mirrlees' original...

Atkinson and Stiglitz show that with weakly separability, differential commodity taxes are unnecessary given an optimal nonlinear income tax. Deaton showed that with an optimal linear progressive income tax, commodity taxes are superfluous under weakly separable and linear Engel curves. Using...

Deaton (1979) showed that if preferences are weakly separable in goods and labour and quasihomothetic in goods and the government imposes an optimal linear progressive tax, commodity taxes are redundant. Hellwig (2009) generalized the Deaton theorem by showing that the allocation obtained under...

We study the optimality of taxing capital income according to a Rate-of-Return Allowance proposed by the Mirrlees Review. In a mean-variance framework the optimal tax on risk-free returns is zero with constant returns to scale in private investment, but positive with decreasing returns to scale,...

We study optimal income and commodity tax policy with credit-constrained low-income households. Workers are assumed to receive an even ow of income during the tax year, but make tax payments or receive transfers at the end of the year. They use their disposable income to purchase multiple...
