This paper reports experimental tests of two alternative explanations of how players use focal points to select equilibria in one-shot coordination games. Cognitive hierarchy theory explains coordination as the result of common beliefs about players' pre-reflective inclinations towards the...

Lying to participants offers an experimenter the enticing prospect ofmaking others' behaviour a controlled variable,but is eschewed by experimental economists because it may pollute thepool of subjects. This paper proposes andimplements a new experimental design, the Conditional...

Consumption surveys often record zero purchases of a good because of a short observation window. Only mean consumption rates can then be inferred. We show that propensity scores can be used to estimate each unit's consumption rate, revealing the distribution. We demonstrate the method using the...

People contribute more to public goods, the more others give ('crowding-in'). We investigate two possible causes of crowding-in: reciprocity, the usual explanation, and conformism, a neglected alternative. The issue is important since conformism has more scope to bring about endogenous social...

Contributions to public goods simulated in economists' laboratoryexperiments have two peculiarities from the perspective ofstatistical modelling. There is a variety of contributor behaviours(Ledyard, 1995), suggestive perhaps of separate classes ofindividuals, and contributions are doubly...
