We introduce the notion of verifiable information into a model of sequential debate among experts who are motivated by career concerns. We show that self-censorship may hamper the efficiency of information aggregation, as experts withhold evidence contradicting the conventional wisdom. In this...

We develop a perpetual youth model to investigate how longevity affects economic growth and welfare. Life expectancy is determined by individuals’ investments in healthcare. We find that improvements in the healthcare technology always increase the steady state growth rate. Although the effect...

The Hotelling rule argues that the price for a nonrenewable resource adjusts to the shadow value of the resource, reflecting the remaining availability of the resource. We empirically test the Hotelling rule on the effect of unanticipated oil field discoveries. We do not find evidence for a...

We present a model of elections in which interest group donations allow candidates to shift policy positions. We show that if donations were prohibited, then a unique equilibrium regarding the position choices of candidates would exist. With unrestricted financing of political campaigns two...

We examine a global refunding scheme for mitigating climate change. Countries pay an initial fee into a global fund that is invested in long-run assets. In each period, part of the fund is distributed among the participating countries in relation to the emission reductions they have achieved in...

We present a Schumpterian model of endogenous growth with General Purpose Technologies (GPTs) that captures two important historical stylized facts: First, from the beginning of mankind until today GPTs are arriving at an increasing frequency and, second, all GPTs heavily depended on previous...

While most countries have harmonized intellectual property rights (IPR) legislation, the dispute about the optimal level of IPR-enforcement remains. This paper develops an endogenous growth framework with two open economies satisfying the classical North-South assumptions to study (a)...

Project-based emissions trading schemes, like the Clean Development Mechanism, are particularly prone to problems of asymmetric information between project parties and the regulator. In this paper, we extend the general framework on incomplete enforcement of policy instruments to reflect the...
