This paper aims to estimate technical and scale efficiency in the Italian citrus farming. Estimation was carried out from two different approach: a non parametric and a parametric approach using a Data Envelopment Analysis (DEA) model and a Stochastic Frontier Analysis (SFA) model, respectively....

By this paper we intend to analyze the existing gap in the efficiency of R&D investment, at European level. The method employed in this respect is Data Envelopment Analysis (DEA). The evaluation of the performance in R&D in European countries, in terms of technical efficiency (TE) thus...

The Japanese government initiated a series of regulatory reforms in the mid-1990s. The Japanese urban gas industry consists of various sized private and non-private firms. Numerous previous studies find that deregulation leads to productivity improvements. We extend the literature by analyzing...

This paper analyzes the role of private storage in a market for a commodity (e.g. natural gas) whose supply is subject to the threat of an irreversible disruption. We focus on the medium term in which seasonality of demand and exhaustibility can be neglected. We characterize the price and...

This paper studies the aggregate substitution and expansion effects triggered by changes in input prices in a context where firms supply a homogeneous commodity and compete in quantities à la Cournot. We derive a sufficient condition for the existence of a Cournot equilibrium and show that this...

Credit unions differ in the types of financial services they offer to their members. This paper explicitly models this observed heterogeneity using a generalized model of endogenous ordered switching. Our approach captures the endogenous choice that credit unions make when adding new products to...

This article estimates returns to scale and monopolistic markups on a large sample of Polish firms in the manufacturing and services sectors during 1996-2004. Methodology based on instrumental variables allows joint estimation of both, scale elasticities as well as markups, while the unobserved...
