In this paper we investigate the influence of institutional investors on share prices using data from companies quoted on the Athens Stock Exchange. For finance theorists the value of an investment, real or financial, is a function of its expected benefits and the riskiness of these benefits....

In this paper, we consider the estimation of the tail indices of distributions in the domain of attraction of stable laws. We follow the approach of Meerschaert and Scheffler (1999), which requires exclusively the spectral decomposition of the uncentered sample moment matrix containing the...

This paper provides a link between the structural approach of econometrics of auctions with the stochastic frontier literature in an effort to model excess bidding behaviour. The new technique is applied to timber auction data. The results suggest that both systematic overbidding and...

Traditional stochastic frontier models impose inefficient behavior on all firms in the sample of interest. If the data under investigation represent a mixture of both fully efficient and inefficient firms then off-the-shelf frontier models are statistically inadequate. We introduce the zero...

This paper analyzes the productivity and efficiency of Turkish banks from 2002 to 2010. We obtained estimates of efficiency, productivity growth and efficiency growth using a Bayesian stochastic frontier approach and focused on accounting for Non-Performing Loans (NPLs) for use in our model....
