摘要：We propose a dynamic oligopoly pricing model, in which consumers' choices exhibit inertia and firms face costly price adjustments. The primitives of the model are estimated using scanner data from the UK butter and margarine industry. We evaluate the effects of frictions on price dynamics, profits and consumer welfare. We find that price adjustment costs are substantial and represent between 24%-34% of net margins. Our model predicts that the absence of these costs reduces persistence in price...

摘要：We design an experiment to analyse the consequences of dark trading in a financial market. The channel through which dark trading affects market efficiency critically depends on how information regarding fundamentals is distributed among investors. When information is concentrated in the hands of a few investors, possibly due to sparse investor connectedness or low media coverage, dark trading primarily impacts market efficiency by deteriorating the quality of asset prices. When information is...

摘要：We conduct an original lab-in-the-field experiment on the decision-making process of married couples over the allocation of rival and non-rival household goods. The experiment measures individual preferences over allocations and traces the process of deferral, consultation, communication and accommodation by which couples implement these preferences. We find few differences in individual preferences over allocations of goods. However, wives and husbands have strong preferences over process: wo...

摘要：Using a natural experiment setting in binary options markets, we compare the evolution of market prices in situations where the occurrence of public information shocks is contingent on knife-edge conditions and can be considered nearly random. We find that prices mostly react efficiently and quickly to information shocks, adjusting to the new fundamental value. Nonetheless, we observe a tendency for prices to initially under-react when the information shocks are large. This under-reaction is s...

摘要：How does anti-American terrorism in recipient countries respond to US military aid? Does aid protect United States interests abroad or does it have unintended consequences for US security? To answer these questions, we estimate the effect of US military aid on anti-American terrorism in recipient countries for a sample of 174 countries between 1968 and 2018. We find that higher levels of aid especially for military financing and education are associated with a higher likelihood of anti-America...

摘要：This paper extends the monopsony literature by taking a task-based approach and estimating the causal effect of concentration on labour market outcomes. Using detailed employer-employee data from Norway, we find that our job task-based measure shows lower degrees of concentration than conventional industry- and occupation-based measures. Exploiting mass lay-offs as exogenous shocks to local labour demand, we show that workers who experience mass separations in more concentrated markets have su...

摘要：There is substantial emphasis on improving classroom practices, primarily through activity-based instruction, to increase the productivity of schooling. We study a large programme that seeks to promote mathematics learning in government primary schools in India. Through a cluster-randomised trial we find that the programme increased activity-based instruction, but yielded only muted impacts on learning. We provide a potential explanation: school value-added models suggest a negative relationsh...

摘要：People care about crime, with the spatial distribution of both actual and perceived crime affecting the local amenities from living in different areas and residential decisions. The literature finds that crime tends to happen close to the offender's residence, but does not clearly establish whether this is because the location of likely offenders and crime opportunities are close to each other, whether more local crimes are likely to be solved or whether there is a high commuting cost for crim...

摘要：Using detailed information from lobbying reports filed under the Lobbying Disclosure Act, we construct a unique dataset that allows us to identify which firms lobby on free trade agreements negotiated by the United States, their positions (in favour or against) and their lobbying efforts on the ratification of each trade agreement. Using this dataset, we show that lobbying on free trade agreements is dominated by large multinational firms, which are in favour of these agreements. On the intens...

摘要：We provide field evidence that individuals engage in motivated optimism in the face of impending risk. Congruent with a dynamic anticipatory utility model, we demonstrate that belief distortions are time and stake dependent. Our study leverages variation in the time span between the survey and the externally imposed date when workers are required to return to their workplaces during the COVID-19 pandemic. We show that, as the work return date approaches, individuals become relatively more opti...
