Law enforcement against illegal drug markets like coca leaf production have created big debate about its consequences and effectiveness. Since this enfocerment does not only affect the illegal market but also the legal ones it is then necessary to study its effects and effectiveness within a...

In this paper we provide a generalization of the standard models of the diffusion of a new product. Consumers are heterogeneous and risk averse, and the firm is uncertain about the demand curve: both learn from past observations. The attitude towards risk has important effects with regard to the...

In this article we discuss the dynamics of organizational change when agents have heterogeneous initial conjectures and do learn. In this framework, conjectural equilibrium is defined as a steady state of the learning process, and all the adjustment occurs in disequilibrium. We discuss the...

In this study we use a unique database covering 25 manufacturing and service sectors for 16 European countries over the period 1996-2005, for a total of 2,295 observations, and apply GMM-SYS panel estimations of a demand-for-labour equation augmented with technology. We find that R&D...

After discussing theory regarding the consequences of technological change on employment and surveying previous microeconometric literature, our aim with this paper is to test the possible job creation effect of business R&D expenditures, using a unique longitudinal database covering 677...

The aim of this paper is to test the employment effect of business R&D expenditures, using a unique longitudinal database covering 677 European manufacturing and service firms over the period 1990-2008. Main result from the whole sample dynamic LSDVC (Least Squared Dummy Variable Corrected)...

We investigate the optimality of the actual degree of Intellectual Property Rights protection using a methodology derived from Patent Race Literature. We applied the methodology to Colombia, using the available two Innovation Surveys. Our result are consistent with an already optimal existing...
