This paper reviews GRETL, a software package for econometrics. Mainly it discusses GRETL's merits as an aid in teaching undergraduate econometrics. This discussion is in two parts. First one author, an instructor, reviews the teaching of undergraduate econometrics with GRETL. Then the second...

This article explores to what extent the poor results that are often found when estimating parameters of production functions can be attributed to measurement errors, due to the use of common price deflators across firms. Because of the lack of detailed micro-economic data, econometricians have...

We find that an important programming error was made by Hobijn and Franses (2000) in conducting multivariate stationarity tests. The empirical results in their paper are subject to errors. Other studies that have used the coded algorithm of Hobijn and Franses are likely to suffer the same...

Within the semiparametric framework introduced by Pendakur (1999) we introduce a new loss function to estimate equivalence scales. This loss function uses all available information from the total expenditures of both the reference and nonreference households and as such it produces more reliable...

Managed care health insurers in the USA restrict their enrollees' choice of hospitals to within specific networks. This paper considers the implications of these restrictions. A three-step econometric model is used to predict consumer preferences over health plans conditional on the hospitals...

This paper uses a dataset collected among inhabitants of Amsterdam, to study the employment effects of the use of cannabis and cocaine. For females no negative effects of drug use on the employment rate are found. For males there is a negative correlation between past cannabis and cocaine use...

Estimation of the linear quadratic model, the workhorse of the inventory literature, traditionally takes inventories and sales to be first-difference stationary series, and the ratio of the two variables to be stationary. However, these assumptions do not always match the properties of the data...

We propose a general double tree structured AR-GARCH model for the analysis of global equity index returns. The model extends previous approaches by incorporating (i) several multivariate thresholds in conditional means and volatilities of index returns and (ii) a richer specification for the...
