摘要：I develop a novel view of the trade frictions between rich and poor countries by arguing that to reconcile bilateral trade volumes and price data within a standard gravity model, the trade frictions between rich and poor countries must be systematically asymmetric, with poor countries facing higher costs to export relative to rich countries. I provide a method to model these asymmetries and demonstrate the merits of my approach relative to alternatives in the trade literature. I then argue tha...

摘要：The success of new technologies depends on both the firms' investment and consumers' usage decisions. We study this problem in a shared ATM network. Inefficiencies may arise because banks coordinate investment, and consumers may not make proper use of the network. Based on an empirical model of ATM investment and demand, we find that banks substantially underinvested in ATMs, in contrast with earlier findings of strategic overinvestment in the United States. Furthermore, ATM usage was too low,...

摘要：We design a field experiment to explore the use of social comparison to increase contributions to an online community. We find that, after receiving behavioral information about the median user's total number of movie ratings, users below the median demonstrate a 530 percent increase in the number of monthly movie ratings, while those above the median decrease their ratings by 62 percent. When given outcome information about the average user's net benefit score, above-average users mainly enga...

摘要：Financial crashes were followed by deep recessions in the Sudden Stops of emerging economies. An equilibrium business cycle model with a collateral constraint explains this phenomenon as a result of the amplification and asymmetry that the constraint induces in the responses of macro-aggregates to shocks. Leverage rises during expansions, and when it rises enough it triggers the constraint, causing a Fisherian deflation that reduces credit and the price and quantity of collateral assets. Outpu...
