This paper considers estimation of moving average (MA) models with non-Gaussian errors. Information in higher-order cumulants allows identification of the parameters without imposing invertibility. By allowing for an unbounded parameter space, the generalized method of moments estimator of the...

Empirical analysis often involves using inexact measures of desired predictors. The bias created by the correlation between the problematic regressors and the error term motivates the need for instrumental variables estimation. This paper considers a class of estimators that can be used when...

The growth of unsolicited commercial email imposes increasing costs on organizations and causes considerable aggravation on the part of email recipients. A thriving anti-spam industry addresses some of the frustration. Regulation and various economic and technical means are in the works –...

We propose an agent-based model to investigate the effects of policies against poverty – income support, workfare policies and active labor market programs within different economic and institutional setting

In recent years simulation-based estimation of multinomial probit (MNP) models has attracted an increasing interest among econometricians. With the help of more powerful and cheaper computers, MNP models have become a well-accepted alternative to multinomial logit (MNL) models that impose the...
