A framework for the optimal taxation of cigarettes based on economic efficiency is provided here. Fundamentally different views of smoking in the context of addictive behavior result in markedly different estimates of the efficient cigarette tax rate. Based on the rational addiction model, more than half of the states may have increased their cigarette excise tax rates to levels beyond the econ...

Previous studies have shown that the optimal marginal tax rate at the bottom of the income distribution may be positive, negative, or even zero. This paper reexamines this problem in a unified framework and tries to evaluate the arguments. It turns out that the case for positive marginal tax rates is quite strong, whereas negative marginal tax rates seem to be based on a misconception.

Using the Mirrlees optimal income tax model, with no income e¤ects on labour supply, this article shows that the discrete population approach provides new insights into the characterization of the optimal tax system, which complements the previous …ndings. The analysis is based on the "Spence-Mirrlees wedge" which corresponds, at each observed gross income level, to a ratio between the marginal...

We determine the second best rule for the inflation tax in monetary general equilibrium models where money is dominated in rate of return. The results in the literature are ambiguous and inconsistent across different monetary environments. We derive and compare the optimal inflation tax solutions across the different environments and find that Friedman's policy recommendation of a zero nominal ...

There is a growing concern among policy makers and analysts regarding the mismatch between demand and supply of the revenue for improving and maintaining highway infrastructure. One possible solution is to link actual vehicle miles traveled (VMT) to the fee structure. The main objective of this paper is to model VMT dynamics and establish a methodology for designing an optimal VMT tax rate. The...

This paper examines the interaction between investment and financing decisions of a firm using a real options approach. The firm is endowed with a perpetual option to invest in a project at any time by incurring an irreversible investment cost at that instant. The amount of the irreversible investment cost is directly related to the intensity of investment that is endogenously chosen by the fir...

We study optimal government policy in an economy where (i) search frictions create a coordination problem and generate multiple Pareto-ranked equilibria and (ii) the government finances the provision of a public good by taxing trade. The government must choose the tax rate before it knows which equilibrium will obtain, and therefore an important part of the problem is determining how the policy...
