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...

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...

This paper studies the excessive volatility of Spanish aggregate non-durables consumption with relation to aggregate income. In this paper we stress the importance of non-durables imports over the variability of total non-durables consumption and we propose a theoretical model that formalizes...

In this paper we construct a simple model of platform price competition with two main novel features. First, platforms endogenously decide the quality of their `access service' and second, each group exhibits preferences not only about the number of agents in the opposite group, but also about...

Our companion article developed a clear conceptual framework of profit sharing between two rival firms and studied the effects of this strategy on each firm's profit under the assumption that each firm decides unilaterally to give away voluntarily a part of its profit to its rival. This article...

This paper advocates that although an absolute notion of poverty should remain an essential ingredient in the evaluation of the standard of living in developing and transition economies, it is time that relative poverty begins to be systematically estimated for those same economies. This...
