This paper compares retrospective and prospective analyses of the effect of flip charts on test scores in rural Kenyan schools. Retrospective estimates that focus on subjects for which flip charts are used suggest that flip charts raise test scores by up to 20 percent of a standard deviation....

This paper investigates the effect of entrepreneurs' personal income tax situations on the growth rates of their enterprises. We analyze the personal income tax returns of a large number of sole proprietors before and after the Tax Reform Act of 1986 and determine how the substantial reductions...

This paper focuses on Social Security benefit claiming behavior, a take-up decision that has been ignored in the previous literature. Using financial calculations and simulations based on an expected utility maximization model, we show that delaying benefit claim for a period of time after...

This paper explores the current tax treatment of non-qualified immediate annuities and distributions from tax-qualified retirement plans in the United States. First, we describe how immediate annuities held outside retirement accounts are taxed. We conclude that the current income tax treatment...

A standard methodology in program evaluation is to use time series variation to compare pre- and post-program outcomes. However, when the timing of a break in a statistical relationship can be determined only by looking at the data, then the usual distribution of the test statistic which assumes...

This paper develops and applies semiparametric econometric methods to estimate the form of selection bias that arises from using nonexperimental comparison groups to evaluate social programs and to test the identifying assumptions that justify three widely-used classes of estimators and our...

This paper deals with the investment effects of regional integration agreements and discusses how such arrangements may affect inward and outward foreign direct investment flows in the integrating region.

We use a survey of 452 Russian shops, most of which were privatized between 1992 and 1993, to measure the importance of alternative channels through which privatization promotes restructuring. Restructuring is measured as capital renovation, change in suppliers, increase in hours that stores...

This paper derives a reduced-form expression for an interestrate in an open economy by incorporating after tax covered interest parity conditions into a simple neo-classical macro model. The result clearly demonstrates that the relationship between an interest rate and variables used to explain...

This paper demonstrates that different rates of taxation on interest income and exchange gains may bias results of hypothesis testing regarding critical aspects of exchange rate behavior. Two problems are discussed specifically. First, it is shown that omission of tax considerations may bias...
