This study compares individual preferences across incentives (i.e., hypothetical vs. real incentives) and over time (i.e. elicitation at two different points in time) in a choice experiment involving charitable donating decisions. We provide evidence of hypothetical bias but little evidence of...

Hypothetical bias is one of the main issues bedeviling the field of nonmarket valuation. The general criticism is that survey responses reflect how people would like to behave, rather than how they actually behave. In our study of climate change and emissions reductions, we took advantage of the...

In this paper we aim - through an 'experimentally-adapted' Contingent Valuation survey - to look into the attributes of Ghanaians' willingness-to-pay for green products. This would help us addressing two main issues: first, from a theoretical point of view, we shall assess whether Ghanaians show...

This paper examines the role of simplified heuristics in the formation of preferences for public goods. Political scientists have suggested that voters use simplified heuristics based on the positions of familiar parties to infer how a proposed policy will affect them and to cast a vote in line...

This paper presents the findings of research intended to investigate the nature of expressed preferences for reducing air pollution impacts. Specifically a contingent valuation (CV) experiment is designed to elicit individuals' values for reducing these impacts and examine how these may change...

We conduct a real-effort task experiment where subjects' performance translates into a donation to a charity. In a within-subjects design we vary the visibility of the donation (no/private/public feedback). Confirming previous studies, we find that subjects' performance increases, that is, they...

We study conditional cooperation based on a sequential two-person linear public good game in which a trusting first contributor can be exploited by a second contributor. After playing this game the first contributor is allowed to punish the second contributor. The consequences of sanctioning...

In an experiment designed to test for expressive voting, Tyran (JPubEc 2004) found a strong positive correlation between the participants' approval to a proposal to donate money for charity and their expected approval rate for fellow voters. This phenomenon can be due to a bandwagon effect or a...

We introduce a generalized theoretical approach to study imitation and subject it to rigorous experimental testing. In our theoretical analysis we find that the different predictions of previous imitation models are due to different informational assumptions, not to different behavioral rules....
