In a principal-agent model under moral hazard we examine the psychological and social motivations of the agent that influence the incentive compatibility condition (ICC) of the agent. Under “firm culture” firms emphasize that high effort is consistent with its culture. Under “industry-wide...

We consider firms' choices between a clean technology that benefits, and a dirty technology that harms, the environment. Green firms are more suited to the clean, and brown firms are more suited to the dirty technology. We use a model derived from complexity theory that takes account of true...

We use the trust and the dictator games to explore the effects of religious identity on trust, trustworthiness, prosociality, and conditional reciprocity within a beliefs-based model. We provide a novel and rigorous theoretical model to derive the relevant predictions, which are then tested in...

We consider a private sector job that offers high-powered incentives and two public sector jobs that produce an identical public good, but only one of them offers opportunities for corruption. Our theoretical predictions relate occupation and effort choices, in these three jobs, to preferences...

We consider the psychological and social foundations of human contributions and punishments in a voluntary contributions mechanism with punishment (VCMP). We eliminate 'dynamic economic linkages' between the two stages of our 'modified' VCMP to rule out other potential explanations. We use a...

We consider income-source-dependent tax evasion and show that this is a generalization of the well-known endowment effect. We show that loss aversion, moral costs, mental accounting, and risk preferences play a key role in explaining key features of source-dependent tax evasion. We provide...

We consider technology choices between green and brown technologies by firms. We use insights from complexity theory and also take account of true uncertainty in designing public policy. The green technology offers relatively higher returns to scale from adoption, and there are type-contingent...

We consider a simple, two period, consumption-savings model with future income uncertainty that examines the interplay of savings, precautionary savings, loss aversion, and risk. We provide the relevant theory, followed by empirical tests based on subject-specific choices, and the measurement of...

We explore the relation between social political identity and prosociality. We first construct a theoretical model to generate predictions for the behavior of players in an ultimatum game who are influenced by social political identity. Then we use a novel subject pool-registered members of...

We propose a theoretical model that embeds social identity concerns, as in Akerlof and Kranton (2000), with inequity averse preferences, as in Fehr and Schmidt (1999). We conduct an artefactual ultimatum game experiment with registered members of British political parties, for whom political...
