摘要：A central feature of social networks is information sharing. The Internet and related computing technologies shape the relative costs of private information acquisition and forming links with others. This article presents an experiment on the effects of changing costs. We find that a decline in relative costs of linking makes private investments more dispersed and gives rise to denser social networks. Aggregate investment falls but individuals' access to investment remains stable, due to incre...

摘要：We explore whether differences in intergenerational income mobility between the UK and Sweden show up early in life, finding stronger associations between parental income and birthweight, height and school performance in the UK. We investigate whether these differentials can account for the country difference in income mobility. While differences in the associations in birthweight and height are too weak to matter, school performance does account for a substantial part of this difference. Howe...

摘要：Expenditure on legal services has been rising and has attracted considerable policy attention in the UK. We argue that an important reason for this increase stems from the introduction of 'no win no fee' schemes in 1995 and a subsequent amendment's in 2000 which allowed claimants to shift additional costs onto losing defendants. We describe how this may have increased expenditure on legal claims and we test for the 2000 amendment effect using a regression discontinuity design on a dataset of e...

摘要：Credence goods markets suffer from inefficiencies caused by superior information of sellers about the surplus-maximising quality. While standard theory predicts that equal mark-up prices solve the credence goods problem if customers can verify the quality received, experimental evidence indicates the opposite. We identify a lack of robustness with respect to heterogeneity in social preferences as a possible cause of this and conduct new experiments that allow for parsimonious identification of...

摘要：Good government requires some restraints on the powerful but how can those be imposed if there is no-one above them? This article studies the equilibrium allocation of power and resources established by self-interested incumbents under the threat of rebellions from inside and outside the group in power. Commitment to uphold individuals' rights can only be achieved if power is not as concentrated as incumbents would like it to be, ex post. Power sharing endogenously enables incumbents to commit...

摘要：We study the short-run and long-run economic impact of one of the largest losses that an individual can face; the death of a child. We utilise unique registers on the entire Swedish population, combining information on the date and cause of death with parental outcomes. We exploit the longitudinal dimension of the data and deal with several selection issues. Losing a child has adverse effects on labour income, employment status, marital status and hospitalisation. The value of policy measures ...

摘要：Muslim societies have been reshaped in recent decades by an Islamic revival. We document a contemporaneous decline in social mobility among educated youth in Egypt, the epicentre of the movement in the Arab world. We then develop a model to show how an unexpected decline in social mobility combined with inequality can produce a religious revival led by the educated middle class. The principal idea is that religion helps individuals to cope with unfulfilled aspirations by adjusting their expect...

摘要：We analyse the effects of different resale mechanisms on bidders' strategies in multi-object uniform-price auctions with asymmetric bidders. Our experiment consists of four treatments: one without resale and three resale treatments that vary the information available and the bargaining mechanism in the resale market. Resale markets induce demand reduction by high-value bidders and speculation by low-value bidders, thus affecting the allocation of the objects on sale. The magnitude of these eff...

摘要：We investigate two critical dimensions of the credibility of empirical economics research: statistical power and bias. We survey 159 empirical economics literatures that draw upon 64,076 estimates of economic parameters reported in more than 6,700 empirical studies. Half of the research areas have nearly 90% of their results under-powered. The median statistical power is 18%, or less. A simple weighted average of those reported results that are adequately powered (power >= 80%) reveals that ne...

摘要：This article presents a model of a rational seller who is actively learning the slope of his demand curve via his pricing strategy. Consequently, this seller optimally experiments with his price. Resulting price patterns show a tendency for discreteness (as observed in the data), which has proved to be a major challenge to most price setting models. The experimentation motive can also replicate the observation that prices are more volatile than costs, as well as the presence of many idiosyncra...
