Factor construction methods are widely used to summarize a large panel of variables by means of a relatively small number of representative factors. We propose a novel factor construction procedure that enjoys the properties of robustness to outliers and of sparsity; that is, having relatively...

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...

See the article in the <I>Annals of Financial Economics</I> (2013). Volume 8, issue 2, pages 1-18.<P> 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...</p></i>

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...

Urban re-development projects may generate various positive as well as negative spatial externalities to the existing population in a given area. This study aims to assess the order of magnitude of the expected net benefits for incumbent residents from a large scale project in the Southern part...

This paper addresses the question to what extent the performance of industrial sites is affected by their local economic structure and accessibility. For this aim, we test for the existence of statistically significant relationships between agglomeration externalities (specialization, diversity,...

The topic of convergence is at the heart of a wide-ranging debate in the growth literature. Empirical studies of convergence differ widely in their theoretical backgrounds, empirical specifications and in their treatment of cross-sectional heterogeneity. Despite these differences, a rate of...

This paper addresses the timing of a location's historical transition from rural to urban activity. We test whether urbanization occurs sooner in places with higher agricultural potential and comparatively lower transport costs, using worldwide data that divide the earth's surface at half-degree...

Innovation and technological change are central to the quest for regional development. In the globally-connected knowledge-driven economy, the relevance of agglomeration forces that rely on proximity continues to increase, paradoxically despite declining real costs of information, communication...
