This article is a review of nonparametric Bayesian Survival Analysis and is a part of a contribution of the Encyclopedia of Biostatistics to be published by John Wiley and Sons Ltd. Most of the prior specifications proposed in the literature since Ferguson's seminal paper are presented witha...

Efficiency scores of production units are measured by their distance to an estimated production frontier. Nonparametric DEA estimators are based on a finite sample of observed production unites and radial distances are considered. We investigate the consistency and the speed of convergence of...

In this paper, we develop a Bayesian analysis of semi-parametric binary choice model. The prior specification of the functional parameter, namely the distribution function of a latent variable, is of the Dirichlet process type and the prior specification of the Euclidean parameter, namely the...

The generalised method of moments (GMM) is combined with the nonparametric estimation of the instrument matrix to obtain an easily computable estimator for the panel probit model. It is based on the specification of the conditional mean of the binary dependent variable in each period, and...

The last 20 years have seen a significant evolution in the literature on horizontal inequity (HI) and have led to two major and "rival" methodological strands, namely, classical HI and reranking. We propose in this paper a class of ethically flexible tools that integrate these two strands.

In applied work economists often seek to relate a given response variable y to some causal parameter mu* associated with it. This parameter usually represents a summarization based on some explanatory variables of the distribution of y, such as a regression function, and treating it as a...

We show that certain the winning bids for certain ebaY auctions obey Benford’s Law. One implication of this is that it is unlikely that these bids are subject to collusion among bidders, or “shilling” on the part of sellers. Parenthetically, we also show that numbers from the naturally...

In this paper we develop flexible techniques for measuring the speed of output convergence between countries when such convergence may be of an unknown non-linear form. We then calculate these convergence speeds for various countries, in terms of half-lives, from two time-series data-sets. These...

In the afermath of Germany's reunification, redesigning their product range was a major challenge for East-German enterprises. At the same time, there were growing signs that Western enterprises reacted to globalization and European integration by increasingly pursuing strategies of...
