A comparison of several approximations to the power function of the likelihood ratio test in covariance structure analysis*

In this paper we compare alternative asymptotic approximations to the power of the likelihood ratio test used in covariance structure analysis for testing the fit of a model. Alternative expressions for the noncentrality parameter (ncp) lead to different approximations to the power function. It appears that for alternative covariance matrices close to the null hypothesis, the alternative ncp's lead to similar values, while for alternative covariance matrices far from H_o the different expressions for the ncp can conflict substantively. Monte Carlo evidence shows that the ncp proposed in Satorra and Saris (1985) gives the most accurate power approximations.     

The adequacy of asymptotic approximations in the near-integrated autoregressive model with dependent errors

We consider the normalized least squares estimator of the parameter in a nearly integrated first-order autoregressive model with dependent errors. In a first step we consider its asymptotic distribution as well as asymptotic expansion up to order O_p(T⁻¹). We derive a limiting moment generating function which enables us to calculate various distributional quantities by numerical integration. A simulation study is performed to assess the adequacy of the asymptotic distribution when the errors are correlated. We focus our attention on two leading cases: MA(1) errors and AR(1) errors. The asymptotic approximations are shown to be inadequate as the MA root gets close to −1 and as the AR root approaches either −1 or 1. Our theoretical analysis helps to explain and understand the simulation results of Schwert (1989) and DeJong, Nankervis, Savin, and Whiteman (1992) concerning the size and power of Phillips and Perron's (1988) unit root test. A companion paper, Nabeya and Perron (1994), presents alternative asymptotic frameworks in the cases where the usual asymptotic distribution fails to provide an adequate approximation to the finite-sample distribution.

Moral suasion: An alternative tax policy strategy? Evidence from a controlled field experiment in Switzerland

With data gained from a controlled field experiment in Switzerland this paper analyses the effects of moral suasion on the timely paying and the timely filling out of the tax form 2001. Comparisons of different tax filing years and multiple regression estimations have been done using these two factors as dependent variables to check if there is a significant difference between the control group and the treatment group. In February 2002 the treatment group received a letter signed by the communes fiscal commissioner containing normative appeals. Results indicate that moral suasion has hardly any effect on taxpayers compliance behaviour. The strongest effect can be observed for the variable tax payments.Received: February 2003, Accepted: June 2004 JEL Classification: H260, H710BennoTorgler: Special thanks are due to the tax administration of Trimbach, especially to Adolf Müller and Gary Bitterli, who offered me the opportunity to collect the data and assisted the project.
