Objectives. To estimate the healthcare resources spent by diabetic patients in Spain during the year 2002. Methods. The present work is a cost-of-illness study. Direct healthcare costs were estimated using rates of DM, based on primary and secondary sources of information. A range of prevalence...

We study the properties of mechanisms for deciding upon the provision of public goods when the feasible set is exogenously given (by financial and/or technological constraints), and individuals' preferences are represented by continuous, increasing and concave utility functions, and we establish...

Non-existence of a pure strategy equilibrium in a Bertrand-Edgeworth duopoly model is analyzed. The standard model is modified to include a list pricing stage and a subsequent price discounting stage. Both firms first simultaneously choose a maximum list price and then decide to lower the price,...

In this paper a consistent estimator for the Binomial distribution in the presence of incidental parameters, or fixed effects, when the underlying probability is a logistic function is derived. The consistent estimator is obtained from the maximization of a conditional likelihood function in...

The substance abuse treatment literature has basically dealt with four important questions: 1) Is treatment effective? 2) Are all programs equally effective? 3) why do programs differ in their effectiveness? and 4) which treatments are most cost-effective?. This paper reviews the substance abuse...

The purpose of this paper is to test for the presence of habit formation in consumption decisions using household panel data. We use the test proposed by Meghir and Weber (1996) and estimate the within -period marginal rate of substitution between commodities, which is robust to the presence of...

In this paper we present a model of war between two rational and completely informed players. We show that in the absence of binding agreements war can be avoided in many cases by one player transferring money to the other player. In most cases, the "rich" country transfers part of her money to...

This article explores the reasons why GMM estimators of production function parameters are generally found to produce unsatisfactory results. I attribute this finding to the inaccurate construction of the variables used in production function analysis. In particular, I suggest that the problem...

In this paper we study the evolution of income inequality for employees and self-employed workers. We highlight the importance of separately analyze these different sources of income to gain a broader understanding of inequality. Using Spanish panel data on income and consumption from the ECPF...

We test how a monopoly, a duopoly and a public monopoly manage and allocate water resources. Stock depletion for the public monopoly is fastest. However, it reaches the optimal stock level towards the end of the experimental sessions. The private monopoly and duopoly maintain inefficiently high...
