We study decentralized and optimal urbanization in a simple multi-sector model of a rural-urban economy focusing on productivity differences and internal trade frictions. We show that even in the absence of the typical externalities studied in the literature, such as agglomeration, congestion or...

Literature in economics and psychology on moral behaviour explores the contexts in which people act in ways that are consistent or inconsistent with their past actions. Such inconsistencies appear to violate economists' assumption of rational consumer behaviour. In this note we show that a...

Ignorance enables individuals to act immorally. This is well known in policy circles, where there is keen interest in lowering moral ignorance. In this paper, we study the (in)elasticity of moral ignorance, with respect to monetary incentives, social norms messages and moral context. We propose...

Do people anticipate the conditions that enable them to manipulate their beliefs when confronted with unpleasant information? We investigate whether individuals seek out the “cognitive flexibility” needed to distort beliefs in self-serving ways, or instead attempt to constrain it, committing...

We investigate how moral considerations, background conditions and risk can trigger resistance to implement trading institutions. We provide survey results on moral opposition to trade on several goods and services like body organs, sex services, surrogate mothers, trade with developing nations,...

We study whether tweets about racial justice predict the offline behaviors of nearly 20,000 US academics. In an audit study, academics that tweet about racial justice discriminate more in favor of minority students than academics that do not tweet about racial justice. Racial justice tweets are...

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...

Within a general equilibrium model, this paper identifies a novel animal welfare externality that occurs if the private animal friendliness in a market economy falls short of the social animal friendliness used by the social planner when determining the efficient allocation. The animal welfare...

We document individual willingness to fight climate change and its behavioral determinants in a large representative sample of US adults. Willingness to fight climate change – as measured through an incentivized donation decision – is highly heterogeneous across the population. Individual...
