摘要：In buyer-seller relationships, offering trade credit to buyers fosters long-term collaboration but seller provision varies systematically as relationships evolve. We study the optimal provision dynamics of trade credit when the seller's information about the buyer is incomplete. We show how the interaction of self-enforcing relational contracts and formal contracts determines optimal payment contract choice. We find that payment contracts can be interpreted as screening technologies and imply ...

摘要：Leading dating platforms usually recommend only a small fraction of users based on users' popularity and similarity, leading to recommendation inequality. We use a stylized matching model from economics to modify existing algorithms to reduce inequality. We evaluate the proposed method through a large-scale field experiment on a dating platform. Experiment results suggest that our recommender reduces inequality, improves predictive accuracy, and leads to substantially more matched couples than...

摘要：We consider markets with heterogeneously ambiguous assets and heterogeneously ambiguity-averse investors whose preferences are a parsimonious extension of the mean-variance framework. We study portfolio choice and trade upon arrival of public information, and show systematic departures from the predictions of standard theory, that occur in the direction of empirical regularities. In particular, our theory speaks to several phenomena in a unified fashion: the asset allocation puzzle, the observ...

摘要：Why is invention strongly positively correlated with parental income not only in the United States but also in Finland, which displays low income inequality and high social mobility? Using data on 1.45 M Finnish individuals and their parents, we find the following: (i) the positive association between parental income and off-spring probability of inventing is greatly reduced when controlling for parental education; (ii) instrumenting for the parents having an MSc degree using distance to neare...

摘要：I consider an environment in which an entrepreneur generates information about the quality of his project prior to contracting with an investor. The investor faces a moral-hazard problem since the entrepreneur may divert the funding for private consumption. I find that the efficient amount of information is generated if and only if the bargaining power of the entrepreneur is high enough. I interpret this result in terms of investors' tightness, competitiveness, and generosity measures. I also ...

摘要：We study the regulation of brokerage in wholesale markets in premodern Central Western Europe. Examining 1,804 sets of rules from 82 cities, we find brokerage was primarily a centralized matchmaking mechanism. Brokerage was more common in towns with larger populations, better access to sea ports and trade routes, and greater political autonomy. Brokers' fee structures varied systematically: price-based fees were more common for highly heterogeneous goods, quantity-based fees for more homogeneo...

摘要：This article analyzes the role of credit frictions in a trade model where producers differ in their capabilities to conduct process and quality innovations and require external finance for investments. Accounting for cost-based and quality-based sorting of firms in a unified framework allows us to demonstrate that the reactions of prices and commonly used productivity measures do not necessarily reflect welfare implications. Credit frictions lead to distortions through aggravated access to fin...

摘要：Economic systems are composed of multiple interrelated groups of agents and with multiple sources of network externalities present. This can give rise to novel systemic risks. We propose a multilayer model to understand this phenomenon. The model features complementary or substitutionary actions of agents active in multiple groups and extends the network concepts of systemic importance and microinduced aggregate fluctuations to their multigroup counterparts. The multilayer allows for the propa...

摘要：This article constructs an overlapping generations general equilibrium model to explore the extent to which heterogeneity in time investment shapes intergenerational mobility of lifetime income. The calibrated model successfully accounts for untargeted distributional aspects of income mobility. Counterfactual exercises show that removing heterogeneity in parental time investment reduces intergenerational persistence by around 7-8% for early childhood but only marginally in later childhood. Pol...

摘要：The consequences of costly information acquisition for sovereign risk are explored in a quantitative sovereign default model. We identify information costs empirically using Bloomberg news-heat data. The calibrated model microfounds heteroskedasticity in the country risk spread as measured by a novel metric we call the Crisis Volatility Ratio (CVR). Crises are endogenously more volatile because more information is acquired and priced. Recalibrated extant models do not generate CVRs in the empi...
