摘要：We examine traders' order submission strategies during the Euronext preopen, which uses price-time priorities to arrange opening trades via a call auction. Preopening order submissions follow a J-shape pattern. Sophisticated proprietary traders arrive late, consistent with information leakage concerns. Slow clients arrive early and place aggressive orders to advertise their trading needs and strategically gain time priority. Their early order submissions often occur in stocks with an increase ...

摘要：Geographic inequalities in healthcare access extend beyond rural-urban divides include socioeconomic, racial, and other disparities. Proximity to hospitals, clinics, healthcare providers, and pharmacies varies widely, posing a challenge in deciding where strategically locate such facilities. Demand for each service depends on local population health, individual preferences, provider capacity, and other factors. This study introduces a novel structural estimate-then-optimize (SETO) framework, c...

摘要：This paper studies surprise clearance as an innovative business model to increase store profit and reduce food waste. A store holding surprise clearance sells surprise bags composed of surplus food that would otherwise go to waste. At the time of ordering, consumers are uncertain about the quantity of food items included in a surprise bag. We model surprise clearance and compare it with both no clearance and transparent clearance, which sets a transparent unit clearance price based on the amou...

摘要：Food ordering and delivery platforms generate online demand for restaurants and deliver food to customers. In return, restaurants pay platforms a commission, typically a percentage of the order amount. Platforms offer partner restaurants the choice of a range of commission rates, rewarding higher commission payments with featured display slots and discounted delivery fees, both of which stimulate demand. Unfortunately, the current environment is grim: Platforms scurry to cover delivery costs, ...

摘要：We provide the first evidence on the long-run returns to private equity in emerging and frontier markets using the cash flows from every equity investment made by the International Finance Corporation across 130 countries over 58 years. Risk-adjusted returns are comparable to the S&P 500, at least from 1961 until 2010. Returns improve with economic growth but decline as banking systems deepen and countries relax capital controls. These results are consistent with the thesis that financial fric...

摘要：This study investigates the potential of market design choices, specifically quality certification, to mitigate racial discrimination in digital marketplaces. Using a regression discontinuity design (RDD) that exploits the discontinuity in Airbnb's Superhost assignment, we find that Black hosts benefit 1.5 times more from the quality certification than other hosts. Moreover, we find compelling evidence that this disproportionate increase does not come at the expense of non-Superhost Black host...

摘要：Existing rivalry research finds that people try harder and perform better when competing against their rivals. However, are there conditions under which rivalry can harm performance? We integrate rivalry theory with regulatory fit theory to propose two moderators of rivalry: individual skill and situational risk for status change. We test our predictions using data from software programming contests involving more than 4.6 million competitive encounters across 16,846 software developers (coder...

摘要：This study investigates the consequences of monetizing a marketplace for product promotion within a digital platform, specifically the Giveaways program on Goodreads.com. Using a natural experiment and fine-grained platform data from 2016 to 2020, we examine how introducing a fixed entry cost for content creators affected both supply and demand in this two-sided market. Our findings reveal significant shifts in marketplace dynamics after monetization: (1) a substantial decrease in overall prog...
