Conditions for the emergence of cooperation in a spatial common-pool resource game are studied. This combines in a unique way local and global interactions. A fixed number of harvesters are located on a spatial grid. Harvesters choose among three strategies: defection, cooperation, and...

We study the conditions for the emergence of cooperation in a spatial common-pool resource game. We consider three types of agents: cooperators, defectors and enforcers. The role of enforcers is to punish defectors for overharvesting the resource. Agents are located around a circle and they only...

This paper investigates the impact of alternative environmental policy instruments on technological innovations aiming to improve energy-efficiency in buildings. The empirical analysis focuses on three main types of policy instruments, namely regulatory energy standards in buildings codes,...

This paper investigates the determinants of directed technical change in the electricity generation sector. We use firm-level data on patents led in renewable (REN) and fossil fuel (FF) technologies by about 7,000 European firms over the period 1978-2006. We separately study specialized firms...

Addressing both the challenge of climate change and the world's growing energy needs will only be possible by achieving a breakthrough in clean technologies in order to deliver safe, clean and sustainable energy for future generations. Such a large-scale technological transition will require...

Disability Insurance (DI) may affect workers' outcomes such as their probability to enter DI, to recover, and their employment. Supplementary insurance may increase these moral hazard effects, but also increases the financial gains of private insurers to reduce benefit costs. With increased...

Workers with fixed-term contracts typically have worse health than workers with permanent contracts. We show that these differences in health translate into a substantially higher (30%) risk of applying for disability insurance (DI) in the Netherlands. Using unique administrative data on health...

Variation in assessor stringency in awarding benefits leaves applicants exposed to uninsured risk that could be systematic if discretion were exercised selectively. We test for this using administrative data on applications to the Dutch disability insurance program. We find that discretion is...
