In this paper, we study the so-called “wrong skewness” anomaly in Stochastic Frontiers (SF), which consists in the observed difference between the expected and estimated sign of the asymmetry of the composite error. We propose a more general and flexible specification of the SF model,...

The stochastic frontier model was first proposed in the context of production function estimation to account for the effect of technical inefficiency. The inefficiency causes actual output to fall below the potential level (that is, the production frontier) and also raises production cost above...

There is a renewed interest in whether land reforms can contribute to market development in Africa and whether land reforms can be pro-poor. This paper uses unique household panel data from Tigray region in Ethiopia to assess the impact of the 1998 low-cost land registration and certification...

Swarna Jayanti Gram Swarojgar Yojona (SGSY), a government sponsored micro credit programme of India, has been designed to ameliorate income poverty among the rural poor, particularly women, through human capital development and strengthening female agency. In this backdrop the basic objectives...

The research estimates a competing risk model of mortgage terminations on a sample of UK securitized subprime mortgages. We consider whether the variety of mortgage contracts that were securitized explains the performance of subprime securities and their supposed ‘idiosyncratic’ behaviour....

We provide a comprehensive overview of latent Markov (LM) models for the analysis of longitudinal data. The main assumption behind these models is that the response variables are conditionally independent given a latent process which follows a first-order Markov chain. We first illustrate the...

This paper studies the causal effect of education on income uncertainty using a broad measure of income which encompasses unemployment risk. To accomplish this, the variance of residuals from a Mincer-type income regression is decomposed into unobserved heterogeneity (known to the individuals...

This paper addresses the issue of unobserved heterogeneity in film characteristics influence on box-office. We argue that the analysis of pooled samples, most common among researchers, does not shed light on underlying segmentations and leads to significantly different estimates obtained by...
