This paper presents experimental evidence that contributions to a public good can bepath-dependent for a limited time span. We study a repeated linear public-good gamewith punishment opportunities. Our data shows that subjects who had experienced ahigher marginal return on public-good...

Previous research indicates that risky and uncertain marginal returnsfrom the public good significantly lower contributions. This paper presentsexperimental results illustrating that the effects of risk and uncertainty dependon the employed parameterization. Specifically, if the value of the...

We examine the effects of leading by example in voluntary contributionexperiments. Leadership is implemented by letting one group membercontribute to the public good before followers do. Such leadershipincreases contributions in comparison to the standard voluntary contributionmechanism,...

We conducted a laboratory study with a public goods game in which contributions are notsubmitted all at once but incrementally as coordinated in real time by a clock. Individualspress a button as soon as the clock equals their willingness to contribute. This publicgoods institution exploits the...

There is currently much hope about environmental innovation and green technologies, notablyas a response to the threat of climate change. This paper offers a critical perspective on the roleof technological innovation to solving environmental problems, based on considering empiricaleconomic...

We study the effect of leadership in an experimental threshold public "bad" game, where we manipulate both the relative returns of two investments (the more productive of which causes a negative externality) and the extent to which the gains from leadership diffuse to the group. The game...

Climate challenge can be modelled as a multiplayer prisoner's dilemma where any ecological action - i.e., purchasing an electric car or adopting sustainable life styles - is a costly action in terms of economic resources, time, and effort for individuals. According to the well-known embedded...
