摘要：In this article we test the implications of a model of network formation on data from rural Ethiopia. In contrast to the current literature, we demonstrate the critical role of both number of links and architecture in determining the impact of social networks on outcomes. Social capital matters, but its impact differs by the architecture of the network to which one belongs.

摘要：How does risk perception affect risk regulation? Happyville is a society in which citizens wrongly believe that the drinking water supply is contaminated. We discuss conditions under which a benevolent Director of Environment Protection would invest in a water cleanup technology. This holds if the Director is populist, namely if he maximises social welfare based on citizens' pessimistic beliefs. More surprisingly, investment in the water cleanup technology may occur if the Director is paternal...

摘要：Using a longitudinal survey from rural Guatemala, we examine the effect of an early childhood nutritional intervention on adult educational outcomes. An intent-to-treat model yields substantial effects of an experimental intervention that provided highly nutritious food supplements to children, a quarter century after it ended: increases of 1.2 grades completed for women and one quarter SD on standardised reading comprehension and non-verbal cognitive ability tests for both women and men. Two-...

摘要：Our laboratory study of risk sharing without commitment captures the main features of a simple model of voluntary insurance. Participants are paired in matches with stochastic endings. Each period they receive fixed endowments and one of the pair (randomly-drawn) also receives an additional amount; they can then make voluntary transfers to each other. While smoothing consumption is attractive, only self-enforcing risk sharing is possible. We find evidence supporting the theory: transfers provi...

摘要：This article examines voluntary provision of a public good that is motivated, in part, to compensate for activities that diminish the public good. Markets for environmental offsets, such as those that promote carbon neutrality, provide an increasingly salient example. An important result is that mean donations do not converge to zero as the economy grows large. The equilibrium is solved to show how direct donations and net contributions depend on wealth and heterogeneous preferences. Comparati...

摘要：In an experimental study we examine a variant of the 'minimum effort game', a coordination game with Pareto ranked equilibria and risk considerations pointing to the least efficient equilibrium. We focus on the question whether simple cues such as smiles, winks and handshakes could be recognised and employed by the players as a tell-tale sign of each other's trustworthiness, thus enabling them to coordinate on the more risky but more rewarding Pareto efficient equilibrium. Our experimental res...

摘要：Using a new database for the late nineteenth century, when the pound sterling was the world's leading international currency, this article provides evidence on the empirical determinants of international currency status. We report evidence in favour of the search-theoretic models to international currencies. Using a microeconomic model of currency choice, we provide empirical support to strategic externalities. We find strong confirmation of the existence of persistence, but reject the view th...

摘要：We model the market for news as a two-sided market where newspapers sell news to readers who value accuracy and sell space to advertisers who value advert-receptive readers. In this setting, monopolistic newspapers under-report or bias news that sufficiently reduces advertiser profits. Paradoxically, increasing the size of advertising eventually leads competing newspapers to reduce advertiser bias. Nonetheless, advertisers can counter this effect if able to commit to news-sensitive cutoff stra...

摘要：We use new data on the location and background of entrants into the US tyre industry to analyse why the industry became so regionally concentrated around Akron, Ohio, a small city with no compelling advantages for tyre production. We analyse where the Ohio entrants originated and conduct various analyses of how proximity to other tyre firms affected the longevity of tyre producers. We also examine how the heritage of the Ohio entrants influenced their origin and longevity. Our findings suggest...

摘要：This article explains contemporaneous exit and entry in a new industry with a diffusion process across submarkets. It allows a re-interpretation of the shakeout process in some industries in a novel way. The industry is a collection of initially inactive independent submarkets; the timing of their activation is determined by an exogenous aggregate diffusion process. New submarket opening attracts new entry. However, the post-entry endogenous sunk investment requirement induced by innovations a...
