This paper investigates whether the answers to commonly used attitudinal survey questions are significantly correlated with actual behavior and checks whether survey questions do exist that provide satisfactory measures of willingness to reciprocate. To address this issue I analyze the data...

This paper proposes a nonparametric method for evaluating treatment effects in the presence of both treatment endogeneity and attrition/non-response bias, using two instrumental variables. Making use of a discrete instrument for the treatment and a continuous instrument for...

This paper considers causal inference and sample selection bias in non-experimental settings in which: (i) few units in the non-experimental comparison group are comparable to the treatment units; and (ii) selecting a subset of comparison units similar to the treatment units is difficult because...

This paper considers causal inference and simple selection bias in non-experimental settings in which: (i) few units in the non-experimental comparison group are comparable to the treatment units; and (ii) selecting a subset of comparison units similar to the treatment unit is difficult because...

The majority of British home and motor insurance policies automatically renew annually, at a price chosen by the provider, unless consumers actively switch or negotiate. Auto-renewal can be beneficial to consumers for example by ensuring continuity of cover. However, the media, consumer groups...

Large amounts of evidence suggest that trust levels in a country are an important determinant of its macroeconomic growth. In this paper, we investigate one channel through which trust might support economic performance: through the levels of patience, also known as time preference in the...
