The structure of a social dilemma lies behind many environmental problems. Mingling temporal aspects of resources with the structure of the social dilemma often leads to wrong conclusions. Therefore, it is worth analytically separating temporal aspects from structural aspects of the dilemma....

This research investigates the hypothesis that publicly funded scientific research complements private R&D investment in the pharmaceutical industry. New microlevel data on public research investment by the U.S. National Institutes of Health allow measures of basic and clinical research in seven...

This paper studies the effects of differential tax treatment toward married and single individuals in the US on marriage formation and composition, divorce and labor supply. We develop a marriage market model with search frictions and heterogeneous agents that is sufficiently rich to capture key...

This paper introduces consumption externalities into a Ramsey-type model with endogenous labour supply and homogeneous agents. The instantaneous utility of any consumer is assumed to depend on work effort, own consumption and relative consumption, where the latter determines the individual's...

This paper presents an endogenous growth model which features elastic labour supply in order to address the distortions created by labour income and consumption taxation. Introducing elastic labour into an AK model greatly changes the structure of the model and raises problems regarding the...

In this paper we analyze the implications of status-preference, modeled as relative wealth, for the current account in a small open economy framework with capital stock dynamics. We demonstrate that the transitional dynamics of the economy is characterized by two distinct speeds of adjustment: a...

This paper extends behavioural microsimulation modelling so that third round effects of a policy change can be simulated. The first round effects relate to fixed hours of work, while second round effects allow for changes in desired hours of work at unchanged wages. These allow for endogenous...

This paper examines the tax schedule for low income families with children. We take an optimal tax approach based on a structural labour supply model which incorporates unobserved heterogeneity, fixed costs of work, childcare costs and the detailed non-convexities of the tax and transfer system....
