摘要：Many governments wish to assess the quality of their universities. A prominent example is the UK's new Research Excellence Framework (REF) 2014. In the REF, peer-review panels will be provided with information on publications and citations. This article suggests a way in which panels could choose the weights to attach to these two indicators. The analysis draws in an intuitive way on the concept of Bayesian updating (where citations gradually reveal information about the initially imperfectly ...

摘要：Detailed panel expenditure data from Spain reveal little evidence of a retirement consumption puzzle in 1985-2004. There is a drop in food at home expenditure in the later years of the sample along with evidence of households paying lower prices for the food they purchase after retirement. However, our findings are consistent with a model that allows for home production as long as one accounts for the greater participation in housework by men after retirement coinciding with this latter period...

摘要：A popular proxy for gun ownership is the fraction of suicides from firearms. This has made identifying the causal effect of guns on suicide difficult. In this article, firearm background checks are used as a proxy for changes in gun ownership rates, allowing the effect of guns on suicide to be identified. The results from panel data regressions show that increases in firearm background checks rates are associated with increases in firearm suicide rates. Overall suicide is positively, but insig...

摘要：Using a combination of randomised field experiments, follow-up telephone surveys and other data collection efforts, this article studies the extent and the sources of ethnic discrimination in the Israeli online market for used cars. We find robust evidence of discrimination against Arab buyers and sellers which, the analysis suggests, is motivated by statistical' rather than taste' considerations. We additionally find that Arab sellers manipulate their ethnic identity in the market by leaving ...

摘要：People have very different beliefs about the risks they face. I analyse how heterogeneous risk perceptions affect the insurance contracts offered by profit-maximising firms. An essential distinction is how risk perceptions affect the willingness to pay for insurance relative to the willingness to exert risk-reducing effort. This determines both the sign of the correlation between risk and insurance coverage in equilibrium, shedding new light on a recent empirical puzzle, and the type of indivi...

摘要：We build a model with financial imperfections and heterogeneous agents and analyse the effects of two types of fiscal policy: revenue-neutral, intratemporal redistribution; and debt-financed tax cuts, which we interpret as intertemporal redistribution. Under flexible prices, the two policies are either neutral or display effects that are at odds with the empirical evidence. With sticky prices, Ricardian equivalence always fails. A Robin Hood, revenue-neutral redistribution to borrowers is expa...

摘要：This article examines the macroeconomic impact of the first round of quantitative easing (QE) by the Bank of England. We attempt to quantify the effects of these purchases by focusing on the impact of lower long-term interest rates on the wider economy. We use three different models to estimate the impact of QE on output and inflation: a large Bayesian vector autoregression (VAR), a change-point structural VAR and a time-varying parameter VAR. Our estimates suggest that QE may have had a peak ...

摘要：We document substantial default effects despite negligible switching costs in a novel setting: television programme choice in Italy. Despite the low costs of clicking the remote and of searching across only six channels and viewers extensive experience with the decision, show choice depends strongly on whether viewers happened to watch the previous programme on the channel. Specifically, male and female viewership of the news depends on whether the preceding programme appealed to men or women,...

摘要：This article proposes a theory of city size distribution via a hierarchy approach rather than the popular random growth process. It does so by formalising central place theory using an equilibrium entry model and specifying the conditions under which city size distribution follows a power law. The force driving the city size differences in this model is the heterogeneity in economies of scale across goods. The city size distribution under a central place hierarchy exhibits a power law if the d...

摘要：This article presents results of innovative surveys that tracked academic high achievers from five countries to wherever they moved in the world to directly measure at the micro level the channels through which high-skilled emigration affects sending countries. There are high levels of emigration and of return and the income gains to the best and brightest from migrating are an order of magnitude greater than any other effect. Most high-skilled migrants from poorer countries remit but involvem...
