摘要：The movement of information technology (IT) workers among firms is believed to be an important mechanism by which IT-related innovations diffuse throughout the economy. We use a newly developed source of employee microdata-an online resume database-to model IT workers' mobility patterns. We find that firms derive significant productivity benefits from the IT investments of other firms from which they hire IT labor. Our estimates indicate that over the last two decades, productivity spillovers ...

摘要：Exchanges sell both trading services and price information. We study how the joint pricing of these products affects price discovery and the distribution of gains from trade in an asset market. A wider dissemination of price information reduces pricing errors and the transfer from liquidity traders to speculators. This effect reduces the fee that speculators are willing to pay for trading. Therefore, to raise its revenue from trading, a for-profit exchange optimally charges a high fee for pric...

摘要：Using a proprietary data set, we analyze the impact of the implementation of a buy-online, pick-up-in-store (BOPS) project. The implementation of this project is associated with a reduction in online sales and an increase in store sales and traffic. These results can be explained by two simultaneous phenomena: (1) additional store sales from customers who use the BOPS functionality and buy additional products in the stores (cross-selling effect) and (2) the shift of some customers from the onl...

摘要：We present examples of existing evidence that lead us to be cautious about claims made in the original paper [Blavatskyy PR (2011) A model of probabilistic choice satisfying first-order stochastic dominance. Management Sci. 57(3):542-548] that the proposed model provides a better fit to experimental data than do existing models. We raise concerns about the accuracy of this and other assertions and about the adequacy of the comparisons made with alternative models in the existing literature.

摘要：This paper presents a dynamic investment game in which firms that are initially identical develop assets that are specialized to different market segments. The model assumes that there are increasing returns to investment in a segment, for example, as a result of word-of-mouth or learning curve effects. I derive three key results: (1) Under certain conditions there is a unique equilibrium in which firms that are only slightly different focus all of their investment in different segments, causi...

摘要：We revisit the model proposed by Gollier and Muermann [Gollier C, Muermann A (2010) Optimal choice and beliefs with ex ante savoring and ex post disappointment. Management Sci. 56(8): 1272-1284; hereafter, GM]. In the GM model, for a given lottery, agents form anticipated expected payoffs and the set of possible anticipations is assumed to be exogenously fixed. We propose sets of possible anticipations that are endogenously determined. This permits us to compare and evaluate in a consistent ma...

摘要：Increasingly detailed consumer information makes sophisticated price discrimination possible. At fine levels of aggregation, demand may not obey standard regularity conditions. We propose a new randomized sales mechanism for such environments. Bidders can buy-it-now at a posted price, or take-a-chance in an auction where the top d > 1 bidders are equally likely to win. The randomized allocation incentivizes high-valuation bidders to buy-it-now. We analyze equilibrium behavior and apply our ana...

摘要：Policy makers have embraced financial education as a necessary antidote to the increasing complexity of consumers' financial decisions over the last generation. We conduct a meta-analysis of the relationship of financial literacy and of financial education to financial behaviors in 168 papers covering 201 prior studies. We find that interventions to improve financial literacy explain only 0.1% of the variance in financial behaviors studied, with weaker effects in low-income samples. Like other...

摘要：To stay abreast of current supply-market pricing, it is common for procurement managers to frequently organize auctions among a pool of qualified suppliers (the supply base). Sole awards can alienate losing suppliers and cause them to defect from the supply base. To maintain the supply base and thereby control the high costs of finding and qualifying new suppliers, buyers often employ split awards, which in turn inflate purchase costs. This results in a trade-off that we investigate in an infi...

摘要：This paper introduces satellite-tracked real-time data from a large fishing firm managing its vertically, horizontally, and geographically linked ships to study the causal impact of integration on total factor productivity (TFP) after the firm acquired its vertically unintegrated contractual fish suppliers. TFP increased 16% among newly integrated ships, whereas it did not vary for already owned ships. Some classic mechanisms such as increased effort due to monitoring do not systematically exp...
