The J test for nonnested regression models often works badly as an asypmtotic test, but it generally works very well when bootstrapped. We provide a theroretical analysis of the J test which explains both of these phenomena. We also propose a modified version of the test which works even better...

A major source of difficulty in the construction of dynamic econometric models is the specification of the timing interval of the relationship between economic variables. The econometric modelling has to use the available data, so it is common practice that when only annual data are available...

This paper aims to identify the cost characteristics of existing firms whenever firms are playing an infinite horizon supergame. Recognizing that, with more than two firms, the problem of which firms exit is quite similar to a coalition formation one, we associate to this supergame a game in...

This paper analyzes how an incumbent's price policy may signal information not only on demand level but also on demand composition. We show that uniform pricing may have advantages over third degree price discrimination when there are informational asymmetries for a monopolist facing threat of...

Bootstrap tests are tests for which the significance level is calculated by some sort of boostrap procedure, which may be parametric or nonparametric. We show that, in many circumstances, the size distortion of a bootstrap P value for a test will be one whole order of magnitude smaller than that...
