We study if and how social preferences extend to risky environments. By providing experimental evidence on different versions of dictator games with risky outcomes, we establish that social preferences of players who give in standard dictator games are best described by concerns for the...

This paper investigates ambiguity attitudes for natural events (temperatures) and how they are updated following new information. Using a general population sample, we first obtain baseline ambiguity attitudes for future weather events based on real temperatures over several past days. Second,...

This study measures the differences in ambiguity attitudes of groups and individuals in the gain and loss domain. We elicit the ambiguity attitudes and ambiguity-generated insensitivity for natural temperature events. We do not find significant differences between individuals and groups in our...

We investigate how burden sharing rules may impact the voluntary provision of a public good which generates heterogeneous benefits to agents. We compare different rule-based contribution schemes that are based on the principle of the smallest common denominator: all agents can suggest a minimum...

The provision of public goods often relies on voluntary contributions and cooperation. While most of the experimental literature focuses on individual contributions, many real-world problems involve the formation of institutions among subgroups (coalitions) of players. International agreements...

This paper studies the voluntary provision of public goods that is partially driven by a desire to offset for individual polluting activities. We first extend existing theory and show that offsets allow a reduction in effective environmental pollution levels while not necessarily extending the...

Political feasibility of emission trading systems may crucially depend on the free initial allocation of emission allowances to energy-intensive industries in order to ameliorate adverse production and employment effects. We investigate the potential trade-off between such compensation and...

In 2005, an EU-wide emissions trading scheme covering major CO2 producing sites shall come into power. The key objective of the trading scheme is to promote cost-efficiency of carbon reduction within the EU. We identify policy-relevant tradeoffs between overall efficiency, compensation and...

Starting in 2005, the EU will implement a CO2 emissions trading scheme. In this paper we show that the outspoken goals of economic efficiency and free allocation of allowances are incompatible with harmonized allocation rules. In general, the assignment of allowances is endogenous and differs...

Implementation of an EU-wide emissions trading system by means of National Allocation Plans is at the core of European environmental policy agenda. Member States are faced with the problem of allocating their national emission budgets under the EU Burden Sharing Agreement between...
