A novel simulation-based methodology is proposed to test the validity of a set of marginal time series models, where the dependence structure between the time series is taken 'directly' from the observed data. The procedure is useful when one wants to summarize the test results for several time...

We introduce the vector-valued t-Riesz distribution for time series models of electricity prices. The t-Riesz distribution extends the well-known Multivariate Student's t distribution by allowing for tail heterogeneity via a vector of degrees of freedom (DoF) parameters. The closed-form density...

This article studies specific aspects of the joint replenishment problem in a realsupply chain setting. Particularly we analyze the effect on inventory performance of havingminimum order quantities for the different products in the joint order, given a complextransportation cost structure. The...

In this paper, we develop a modified maximum likelihood (MML) estimator for the multiple linear regression model with underlying student t distribution. We obtain the closed form of the estimators, derive the asymptotic properties, and demonstrate that the MML estimator is more appropriate for...

This paper studies the effects of local marriage markets on South African women’s marital decisions. The analysis is motivated by the low proportion of married among African mothers since 48% are never married. This means that the children of all these never married mothers have no access to...

This paper investigates the effect of sibship size and birth order on educational attainment, for the United States and the Netherlands. An instrumental variables approach is used to identify the effect of sibship size. Instruments for the number of children are twins at last birth and the sex...

Teenage motherhood is very high in South Africa. In 2001, 55 per thousand African South African women and 82 per thousand Coloured South African women were teenage mothers as compared to 8 among Indian South Africans and 3 among White South African women. In this paper we use the South African...

This paper examines how the distribution of prices changes with the number of competitors in the market. Using gasoline price data from the Netherlands we find that as competition increases, the distribution of prices spreads out: the low prices go down while the high prices go up, on average....

We analyze the determinants of female labor market participation for different age-groups in the European Union. We show that female participation is positively affected by tertiary education at any age. But upper secondary education increases participation only up to an age of 40 while after...

This paper is dating from 1995, when it has been presented at the Ragnar Frisch Centennial Memorial Conference in Oslo. It has never been published before.In this paper for the first time the Cantril ladder question data have been employed in the way which later has become known as happiness...
