Noise is a major urban problem that has not received much attention from environmental economists. In this paper we present an attempt to value a noise reduction program in a Spanish city. Contingent valuation has been applied using both one and one-half bound and open-ended question formats....

This is a model of technology adoption that takes seriosly the fact that new inventions are specific to the enviromment in which they emerge. The key feature of the model is that the firm can invest resources in R&D to adapt externally originated ideas to the environment in which they are used....

The paper presents a unified framework where claim and cost sharing problems are jointly analyzed. Both problems have the following common characteristic: given a proposal the agents valuate the suitability of the proposal in two ways, checking how much they loss and how much they gain. Taking...

This paper describes a model with sticky prices, search frictions and hours-clearing wages that provides firm differentiation across several dimensions: price, output, wage, employment and hours per worker. The connection between pricing and hiring decisions results in firm-level employment...

The aim of this research is to model altruistic blood and organ donors behaviour. First, we make an analysis of the decision of to be or not to be a donor for any individual. We propose a model where individuals compare the expected utility of deciding to become a donor, with the utility of the...

Erceg, Henderson and Levin (2000, Journal of Monetary Economics) introduce sticky wages in a New-Keynesian general-equilibrium model. Alternatively, it is shown here how wage stickiness may bring unemployment fluctuations into a New-Keynesian model. Using Bayesian econometric techniques, both...

Leniency clauses, offering cartelists legal immunity if they blow the whistle on each other, is a recent anti-trust innovation. The authorities wish to thwart cartels and promote competition. This effect is not evident, however; whistle-blowing may enforce trust and collusion by providing a tool...

Firing costs are often blamed for unemployment. In this paper, we investigate this widespread belief theoretically. Firing costs are introduced in a efficiency wage model to capture their effects on employment through wages. In addition, dismissal conflicts are modelled explicitly and their cost...

This paper studies the steady-state and transitional dynamics predictions of an R&D-based growth model and evaluates their performance in explaining income disparities across countries. We find that even though steady-state conditions di slightly better at predicting schooling enrollment and...

In Economic Theory, development is the topic, which delves into human welfare. Its aim is linked to welfare expansion in the context of regions. In this working paper, I am assuming that aims and strategies of development are linked to the evolution of welfare notion. At the same time, this...
