摘要：In this article, we provide direct evidence on the behaviour of markups in the retail sector across space and time. Markups are measured using gross margins. We consider three levels of aggregation: the retail sector as a whole, the firm, and the product level. We find that: (1) markups are relatively stable over time and mildly procyclical; (2) there is a large regional dispersion in markups; (3) there is a positive cross-sectional correlation between local income and local markups; and (4) d...

摘要：As a complement to the federal earned income tax credit (EITC), some states offer their own EITC, typically calculated as a percentage of the federal EITC. In this paper, we analyse the effect of state EITC on education using policy discontinuities at US state borders. Our estimates reveal that an increase in the state EITC leads to a statistically significant increase in the high school dropout rate. We then use a life-cycle matching model with directed search and endogenous educational choic...

摘要：How do movements in the distributions of bank size and income affect the macroeconomy? To answer this question, we develop a dynamic general equilibrium model with heterogeneous financial intermediaries, incomplete markets, and aggregate uncertainty. We find that market incompleteness and uninsured idiosyncratic bank rate of return risk generate minimal concentration in the bank net worth distribution, leading to an as-if result, whereby the economy behaves as if it had a representative bank. ...

摘要：What characteristics of news generate over-or-underreaction? We study the asset-pricing consequences of diagnostic expectations, a model of belief formation based on the representativeness heuristic, in a setting where news events are drawn from categories with extreme distributions of fundamentals. Our model predicts greater overreaction to news belonging to categories with more extreme outliers, or tail events. We test our theory on a comprehensive database of corporate news that includes ne...

摘要：This article studies the efficient allocation in an economy in which firms are connected through input-output linkages and must pay a fixed cost to produce. When economic conditions are poor, some firms might decide not to operate, thereby severing the links with their neighbours and changing the structure of the production network. Since producers benefit from having access to additional suppliers, nearby firms tend to operate, or not, together. As a result, the production network features cl...

摘要：Do workers from social groups with comparable productivity distributions obtain comparable lifetime earnings? We study how a small amount of early-career discrimination propagates over time when workers' productivity is revealed through employment. In breakdown learning environments that primarily track on-the-job failures, such discrimination spirals into a substantial lifetime earnings gap for groups of comparable productivity, whereas in breakthrough learning environments that track success...

摘要：In a data economy, transactions of goods and services generate data, which is stored, traded and depreciates. How are the economics of this economy different from traditional production economies? How do these differences matter for measurement of GDP, firm values, depreciation rates, welfare and externalities? We incorporate active experimentation and data as an intangible asset to devise a tractable recursive representation of the data economy. The model rationalizes why apps are often free ...

摘要：Do periods of persistently loose monetary policy increase financial fragility and the likelihood of a financial crisis? This is a central question for policymakers, yet the literature does not provide systematic empirical evidence about this link at the aggregate level. In this article, we fill this gap by analysing long-run historical data. We find that when the stance of monetary policy is accommodative over an extended period, the likelihood of financial turmoil in the medium term increases...

摘要：I study racial disparities in the criminal justice system by analysing abnormal bunching in the distribution of crack-cocaine amounts used in federal sentencing. I compare cases sentenced before and after the Fair Sentencing Act, a 2010 law that changed the 10-year mandatory minimum threshold for crack-cocaine from 50 g to 280 g. First, I find that after 2010, there is a sharp increase in the fraction of cases sentenced at 280 g (the point that now triggers a 10-year mandatory minimum), and th...

摘要：I study linear panel data models with predetermined regressors (such as lagged dependent variables) where coefficients are individual-specific, allowing for heterogeneity in the effects of the regressors on the dependent variable. I show that the model is not point-identified in a short panel context but rather partially identified, and I characterize the identified sets for the mean, variance, and CDF of the coefficient distribution. This characterization is general, accommodating discrete, c...
