Abstract: Data depth measures the centrality of a point with respect to a given distribution or data cloud. It provides a natural center-outward ordering of multivariate data points and yields a systematic nonparametric multivariate analysis scheme. In particular, the halfspace depth is shown to...

Using a novel enterprise survey from Kenya (FinAccess Business), we document a strong positive association between the use of mobile money as a method to pay suppliers and access to trade credit. We develop a dynamic general equilibrium model with heterogeneous entrepreneurs, imperfect credit...

Data depth measures the centrality of a point with respect to a given distribution or data cloud. It provides a natural center-outward ordering of multivariate data points and yields a systematic nonparametric multivariate analysis scheme. In particular, the halfspace depth is shown to have...

This paper provides locally optimal pseudo-Gaussian and rank-based tests for<br/>the cointegration rank in linear cointegrated error-correction models with i.i.d.<br/>elliptical innovations. The proposed tests are asymptotically distribution-free,<br/>hence their validity does not depend on the actual...

In this paper a new class of relaxed sequencing games is introduced: the class<br/>of Step out - Step in sequencing games. In this relaxation any player within a coalition is allowed to step out from his position in the processing order and to<br/>step in at any position later in the processing order....

A positive relation between confidence and effort/investment provision has been<br/>theoretically justified and practically assumed in the literature, but has not been<br/>thoroughly investigated. We test and confirm this positive relation between direct<br/>measures of confidence and choice of effort or...

We present the results from a natural experiment in which single mothers on welfare were stimulated to find a job. Two policy instruments were introduced: an earnings disregard and job creation. The experiment was performed at the level of municipalities in The Netherlands, a country with...

The art market is subject to frequent booms and busts in both prices and volume,<br/>which are difficult to reconcile with models where agents are rational and<br/>hold homogenous beliefs. This paper shows that (i) volume is mainly driven by<br/>speculative transactions; (ii) positive price-volume correlation...

Cloud computing technologies have the potential to increase innovation and economic growth considerably. But many users worry that data in the cloud can be accessed by others, thereby damaging the data owner. Consequently, they do not use cloud technologies up to the efficient level. I design an...
