Experts,Information, Reviews,and Coordination: Evidence on How Prizes Affect Sales*

Exploiting the award process, we implement a regression discontinuity design to estimate the effect of winning France's main literary prize, the Goncourt. It increases sales, especially for books that sold fewer copies before the announcement, the number of reviews on Amazon, and the probability of them being negative. The effect is partly driven by an increase in word of mouth. Those findings are consistent with a model where the prize provides information on the existence of a book and acts as a quality signal and a coordination device but prompts consumers to read books that are far from their tastes.     

Consumer Search in Retail Gasoline Markets

This paper develops direct tests for search behavior in retail gasoline markets. We exploit a unique market‐level dataset that allows us to directly measure search intensity with daily web traffic data from a gasoline price reporting website and perfectly measure daily changes in price levels and dispersion. Our simple yet powerful tests provide strong evidence of both cross‐sectional and intertemporal price search.     

INFORMATION AND PRICE DISPERSION: THEORY AND EVIDENCE

Limited information is the key element generating price dispersion in models of homogeneous-goods markets. We show that the global relationship between information and price dispersion is an inverse-U shape. We test this mechanism for the retail gasoline market using a new measure of information based on commuter data from Austria. Commuters sample gasoline prices on their commuting route, providing us with spatial variation in the share of informed consumers. Our empirical estimates are in line with the theoretical predictions. We also quantify how information affects average prices paid and the distribution of surplus in the gasoline market.     

Psychological Capital: Impacts on Asset Management

Drawing together the areas of behavioral finance and positive psychology, the present research sought to investigate whether the psychological capital of investment fund managers is associated with fund performance in a context of financial instability. The theoretical propositions were presented and evaluated empirically through primary data on investment fund manager profiles and secondary data on the cumulative stock fund returns. The results indicate that funds managed by managers with greater resilience and optimism obtained a higher return than the mean profitability in a period of market instability.     

Switching costs and implicit contracts

When firms can discriminate between old and new customers and when multiperiod binding commitments are too costly, the effects of switching costs may be mitigated thanks to implicit contracts offered (competitively) by firms in equilibrium and backed by reputation.     

Financial Market Imperfections and the Impact of Exchange Rate Movements on Exports*

This paper analyzes empirically the role of financial market imperfections in the way countries’ exports react to a currency depreciation. Using quarterly data for 27 developed and developing countries over the period 1990–2005, we find that the impact of a depreciation on exports will be less positive—or even negative—for a country if: (i) firms borrow in foreign currency; (ii) they are credit constrained; (iii) they are specialized in industries that require more external capital; (iv) the magnitude of depreciation or devaluation is large. This last result emphasizes the existence of a nonlinear relationship between an exchange rate depreciation and the reaction of a country's exports when financial imperfections are observed. This offers a new explanation for the consequences of recent currency crises in middle‐income countries.     

Adjustment Costs,Uncertainty, and the Level of Activity

What is the effect of adjustment costs on economic activity? This is an important question that is still debated either at the political or the academic level. We consider a simple model where basically two effects come into play: Adjustment costs decrease current activity but may help maintain future activity. We examine their relative strength, first in a model with uncertain prices and then in a model with demand uncertainty (newsboy problem).
