This paper extends Hotelling's model of price competition with quadratic transportation costs from a line to graphs. I propose an algorithm to calculate firm-level demand for any given graph, conditional on prices and firm locations. One feature of graph models of price competition is that...

We investigate numerically how indexation of funded pensions for inflation can be differ-

We study whether the Sarbanes-Oxley Act (SOX) of 2002 made firms less opaque. For identification, we use a difference-in-differences estimation approach and compare EU firms that are cross-listed in the US—and therefore subject to SOX—with comparable EU firms that are not cross-listed. We...

We propose new forecast combination schemes for predicting turning points of business cycles. The combination schemes deal with the forecasting performance of a given set of models and possibly providing better turning point predictions. We consider turning point predictions generated by...

Cooperative games with partial cooperation cover a wider rank of real world situations than the classic model of cooperative games where every subset of a set of agents can form a coalition to execute the game. In this paper, the set of feasible coalitions which models the partial cooperation...

This is the first study to analyze effects of in utero exposure to the severe Dutch Hunger Winter famine (1944/45) on labor market outcomes and hospitalization. This famine is clearly demarcated in time and space. It was not anticipated. Nutritional conditions were stable before and after the...

This paper studies the incentives to merge in a Bertrand competition model where firms sell differentiated

We study whether and when parameter-driven time-varying parameter models lead to forecasting gains over observation-driven models. We consider dynamic count, intensity, duration, volatility and copula models, including new specifications that have not been studied earlier in the literature. In...

Elderly home-owners get institutionalized less often than renters do. We hypothesize that housing tenure itself explains this behavior. Using longitudinal data from a Dutch community sample (N= 2,372) collected between 1992 and 2005, we find a negative effect of housing tenure on the probability...

Item response theory is one of the modern test theories with applications in educational and psychological testing. Recent developments made it possible to characterize some desired properties in terms of a collection of manifest ones, so that hypothesis tests on these traits can, in principle,...
