This paper uses a difference-in-difference framework to estimate the effects of mobile money transfer technology (MMT) on healthcare usage in the face of negative health shocks. We use survey data from 2013-16 with quarterly observations on about 1,600 households of 10 villages in the Kisumu...

This article examines how to treat human capital -- perhaps the vast majority of the capital stock -- under an ideal, Haig-Simons income tax. Innate ability, investments in human capital, and uncertainty in future earnings are considered. It is demonstrated that conventional income tax treatment...

The trends in executive pay and labor income tax rates since the 1940s suggest a high elasticity of taxable income with respect to tax policy. By contrast, the level and structure of executive compensation have been largely unresponsive to tax incentives since the 1980s. However, the relative...

The next section shows that many parallel tax systems share common features and constructs a general model of the cost of capital based on the Hall-Jorgenson (1967) cost of capital formula.

The two main workhorses of state tax systems are levies on sales and individual incomes. In this paper we develop and implement a coherent methodology for characterizing these systems. The measures thus generated are used to show how the various systems differ across states, and how they evolved...

Whether personal income tax deductions are appropriate refinements to the concept of income or unwarranted tax expenditures continues to be the subject of debate. The casualty loss and medical expense deductions are frequently justified on the ground that ability to pay is reduced by largely...
