This paper revisited the analytics of the welfare significance of market imperfections using the industry concentration index. It reopened the issue of how best to measure the concentration index. Specifically, it developed a new market concentration index based on the Hirschman- Herfindahl...

The theory of asset pricing, which takes its roots in the Arrow-Debreu model (Theory of value [1959, chap. 7]), the Black and Sholes formula (1973) and Cox and Ross (1976 a and b), has been formalized in a general framework by Harrison and Kreps (1979), Harrison and Pliska (1979) and Kreps...

The purpose of this paper is to provide reasonable estimates for the welfare cost of environmental tax reform in the U.S. economy. Unlike most previous studies that empirically evaluate the deadweight cost of taxation, the model employed here considers explicitly the joint allocation of leisure...

New Zealand is unusual in that nearly 60% of local services are funded from property taxes. These are a mixture of land taxes, capital value taxes, annual rental value taxes and uniform general charges. We explore the efficiency and equity of this system at both national and local levels. We...

This paper is intended as a step toward the development of theoretically founded and operational environmental taxation formula in a second-best world. Recent studies find that environmental taxes typically exacerbate pre-existing tax distortions and, therefore, the optimal pollution tax should...

I propose the replacement of our current system of individual and corporate income, sales, excise, capital gains, import and export duties, gift and estate taxes with a single comprehensive “revenue neutral” Automated Payment Transaction (APT) tax. The APT tax consists of a flat rate tax...

This paper provides a model of nonlinear income taxation in a context of international mobility. We consider two identical countries, in which each government chooses non-cooperatively redistributive taxes. It is shown that when skilled workers can move at low cost, the income taxation does not...

Americans drive 2,360,000,000,000 miles each year, far outstripping other nations. Every time a driver takes to the road, and with each mile she drives, she exposes herself and others to the risk of accident. Insurance premiums are only weakly linked to mileage, however and have largely lump-sum...

If, in international agreements, governments “link'' trade to environmental policy (or other issues with non-pecuniary externalities), will this promote more cooperation in both policies or will cooperation in one policy be strengthened at the expense of the other? We analyze this question in...

This study estimates parameters necessary to calculate the optimal second-best gasoline tax, most notably the cross-price elasticity between gasoline and leisure. Prior work indicates that in a second-best setting with distortionary income taxes, both the cost of environmental regulation and the...
