The endowment effect, the tendency to value possessions more than non-possessions, is a well-known departure from rational choice and has been replicated in numerous settings. We investigate the universality of the endowment effect, its evolutionary significance, and its dependence on environmental factors. We experimentally test for the endowment effect in an isolated and evolutionarily relevant population of hunter-gatherers, the Hadza Bushmen of Northern Tanzania. We find that Hadza living in isolated regions do not display the endowment effect, while Hadza living in a geographic region with increased exposure to modern society and markets do display the endowment effect.

Can Mentoring Help Female Assistant Professors? Interim Results from a Randomized Trial by Francine D. Blau, Janet M. Currie, Rachel T. A. Croson and Donna K. Ginther. Published in volume 100, issue 2, pages 348-52 of American Economic Review, May 2010

ABSTRACT We show that sovereign debt impairments can have a significant effect on financial markets and real economies through a credit ratings channel. Specifically, we find that firms reduce their investment and reliance on credit markets due to a rising cost of debt capital following a sovereign rating downgrade. We identify these effects by exploiting exogenous variation in corporate ratings due to rating agencies' sovereign ceiling policies, which require that firms' ratings remain at or below the sovereign rating of their country of domicile.

ABSTRACT We examine the impact of mandatory portfolio disclosure by mutual funds on stock liquidity and fund performance. We develop a model of informed trading with disclosure and test its predictions using the May 2004 SEC regulation requiring more frequent disclosure. Stocks with higher fund ownership, especially those held by more informed funds or subject to greater information asymmetry, experience larger increases in liquidity after the regulation change. More informed funds, especially those holding stocks with greater information asymmetry, experience greater performance deterioration after the regulation change. Overall, mandatory disclosure improves stock liquidity but imposes costs on informed investors.

Leading financial scholars present essays examining the performance of the basic financial functions underlying global financial systems: payments, lending and investing, pooling funds, allocating risk, providing information, and dealing with incentive issues - with particular emphasis on how their performance is changing and implications for the future.

This study examines why people initially give to charities, why they remain committed to the cause, and what factors attenuate these influences. Using an experimental design that links donations across distinct treatments separated in time, we present several results. For example, previous donors are more likely to give, and contribute more, than other donor types. Yet, how previous donors were acquired is critical: agents initially attracted by an economic mechanism are more likely to continue giving than agents attracted by a nonmechanism factor. From a methodological viewpoint, our study showcases the benefit of moving beyond an experimental design that focuses on short-run substitution effects. (JEL C93, D64, D82, H41, L31, Z12)

We investigate how skills developed when children are 3–5 years old drive schooling outcomes in middle childhood and adolescence. We find that skills map onto three distinct factors—cognitive skills, executive functions, and economic preferences. Importantly, each of the three factors predict later schooling outcomes. While early executive function skills and cognitive scores are linked to future behavioral patterns and other key student outcomes, economic preferences have an independent effect: children who are impatient in early childhood have more disciplinary referrals. Finally, random assignment to preschool impacts grades and disciplinary referrals through changes to cognitive skills and executive functions.

We build a bridge between relationship lending and transactions lending—investigating relationship effects on contract terms for credit cards, a relatively pure transactions-lending technology. Using more than 1 million accounts, we find that during normal times, consumers with relationships obtain better terms but small businesses with relationships do not. Both groups obtain improved terms during COVID-19, consistent with intertemporal smoothing—relationship borrowers obtain more favorable terms during crises, paid for by worse terms in normal times. Among other findings, CARES Act impediments to reporting consumer delinquencies to credit bureaus, designed to protect customers, reduced informational value of credit scores, penalizing safer consumers.

ABSTRACT This study examines the association between a shared common auditor among suppliers and customers and trade credit. Using hand-collected pairwise trade credit data, we find that a supplier extends more trade credit to a customer audited by a common auditor. This association is robust to alternative design specifications and various sample restrictions to alleviate selection bias. We then interview trade credit managers and executives as a prelude to archival analyses exploring multiple potential mechanisms to explain this association. The collective results are most consistent with the explanation that mutual third parties to a dyadic relationship can foster trust through social connections and increased salience of reputation effects rather than that a common auditor reduces information asymmetry about the rigor of the audit process.
