Bootstrap tests are tests for which the significance level is calculated by some sort of bootstrap procedure, which may be parametric or nonparametric. We provide a theoretical framework in which to study the size distorsions of bootstrap P values. We show that, in many circumstances, the size...

In this paper we assess, via Monte Carlo Simulations, the effects of some seasonal adjustment linear filters on cointegrating regressions. We find that the use of filters has adverse consequences in terms of the power of the Augmented Dickey and Fuller and Phillips and Perron tests of cointegration.

In addition to showing the connection between parallel contingent and noncontingent risk comparison problems, we articulate a method for solving both kinds of problems using the "basis" approach. The basis approach has often been used implicitly, but we argue that there is value to making its...

In this paper, we compare the attitude towards current risk of two expected-utility-maximizing investors that are identical except that the first investor will live longer than the second one.

In this paper, we show how a differentiated tax treatment of corporate losses and corporate profits induces the firm to behave in a very specific risk-averse manner.
