This paper investigates whether smokers exhibit greater time discounting than non-smokers, and how short-term nicotine deprivation affects time discounting. A unique feature of our experiment is that our subjects receive rewards not only of money, but also of actual tobacco. This is done in...

Empirical studies of tropical forest hunting have shown the existence of marked spatial gradients of hunting effort, game harvest, and animal abundance, as hunters mostly hunt near villages, roads, and rivers. The mechanisms underlying these patterns have, however, hitherto been poorly known....

This paper presents the results of a threshold public goods game experiment with heterogeneous players. The experiment is designed in close collaboration with the Dutch association of agri-environmental farmer collectives. Subjects are recruited at a university (“the lab”) and a farm...

We contribute to the literature on the optimal design of auction mechanisms for the procurement of nature conservation activities. We use an economic experiment to examine whether the market efficiency of conservation auctions increases or decreases with repetition. Theory predicts that...

We assess the impact of different crowdfunding designs on the success of crowdfunded public goods using a lab-in-the-field experiment. Our design treatments aim to increase the efficiency of crowdfunding campaigns by raising aggregate contributions and decreasing possible coordination problems...

We conduct a framed field experiment in Mindoro, Philippines on ecological altruism. Behavioral differences between ethnic groups in Mindoro, the Tagalogs and the Mangyans, were investigated. We design a two-part donation task (i.e. dictator game) where the recipient of the donation is a local...

The range of benefits for humans and biodiversity conservation provided by urban green spaces (UGS) receives substantial attention in relation to urban planning and management. However, little is known about the value of nature in UGS. We developed a graphical measurement scale for the...

This study explores Ethiopian farmers’ propensity to adopt sustainable management strategies to rehabilitate small rivers and streams in terms of practices that improve ecological conditions but also have positive impacts on the provisioning ecosystem services (ES) generated by their...

Over the last decades, there has been a growing interest in evaluating the effectiveness of conservation programs, including the presence of unintended effects in areas not covered by a program, so called spillovers. For example, payments for ecosystem services (PES) can have spillover effects...
