摘要：We combine georeferenced data on mining extraction of 14 minerals with information on conflict events at spatial resolution of 0.5 o x 0.5 o for all of Africa between 1997 and 2010. Exploiting exogenous variations in world prices, we find a positive impact of mining on conflict at the local level. Quantitatively, our estimates suggest that the historical rise in mineral prices (commodity super-cycle) might explain up to one-fourth of the average level of violence across African countries over ...

摘要：We demonstrate that eponymy-firms being named after their owners-is linked to superior firm performance, but is relatively uncommon (about 19 percent of firms in our data). We propose an explanation based on eponymy creating an association between the entrepreneur and her firm that increases the reputational benefits/costs of successful/unsuccessful outcomes. We develop a corresponding signaling model, which further predicts that these effects will be stronger for entrepreneurs with rarer name...

摘要：We study a common value, first-price auction in which the number of bidders is endogenous: the seller (auctioneer) knows the value and solicits bidders at a cost. The number of bidders, which is unobservable, may thus depend on the true value. Therefore, being solicited conveys information. This solicitation effect may soften competition and impede information aggregation. Under certain conditions, there is an equilibrium in which the seller solicits many bidders, yet the resulting price is no...

摘要：Rothstein (2017) successfully replicates Chetty, Friedman, and Rockoff's (2014a, b)-henceforth, CFR's-results using data from North Carolina, but raises concerns about CFR's methods. We show that Rothstein's methodological critiques are invalid by presenting simulations and supplementary empirical evidence which show that (i) his preferred imputation of missing data generates bias; (ii) his placebo test rejects valid research designs; and (iii) his method of controlling for covariates yields i...

摘要：Crowdfunding provides innovation in enabling entrepreneurs to contract with consumers before investment. Under aggregate demand uncertainty, this improves screening for valuable projects. Entrepreneurial moral hazard and private cost information threatens this benefit. Crowdfunding's after-markets enable consumers to actively implement deferred payments and thereby manage moral hazard. Popular crowdfunding platforms offer schemes that allow consumers to do so through conditional pledging behav...

摘要：We develop a novel framework to analyze the structural implications of the marriage market for household consumption. We define a revealed preference characterization of efficient household consumption when the marriage is stable. We characterize stable marriage with intrahousehold (consumption) transfers but without assuming transferable utility. Our revealed preference characterization generates testable conditions even with a single observation per household and heterogeneous individual pre...

摘要：Urban growth requires the replacement of outdated buildings, yet growth may be restricted when landowners do not internalize positive spillover effects from their own reconstruction. The Boston Fire of 1872 created an opportunity for widespread simultaneous reconstruction, initiating a virtuous circle in which building upgrades encouraged further upgrades of nearby buildings. Land values increased substantially among burned plots and nearby unburned plots, capitalizing economic gains comparabl...

摘要：We study the impact of providing school report cards with test scores on subsequent test scores, prices, and enrollment in markets with multiple public and private providers. A randomly selected half of our sample villages (markets) received report cards. This increased test scores by 0.11 standard deviations, decreased private school fees by 17 percent, and increased primary enrollment by 4.5 percent. Heterogeneity in the treatment impact by initial school test scores is consistent with canon...

摘要：This paper introduces a new IV strategy based on IVF (in vitro fertilization) induced fertility variation among childless women to estimate the causal effect of having children on their career. For this purpose, we use administrative data on IVF treated women in Denmark. Because observed chances of IVF success do not depend on labor market histories, IVF treatment success provides a plausible instrument for childbearing. Our IV estimates indicate that fertility effects on earnings are: (i) neg...
