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...
