摘要：In several transportation systems, vehicles can choose where to meet customers rather than stopping in fixed locations. This added flexibility, however, requires coordination between vehicles and customers that adds complexity to routing operations. This paper develops scalable algorithms to optimize these operations. First, we solve the one-stop subproblem in the l(1) space and the l(2) space by leveraging the geometric structure of operations. Second, to solve a multistop problem, we embed t...

摘要：Brand valuation methods traditionally focus on the value a brand generates via its ability to enhance demand and, accordingly, profitability. However, this paper explores how a brand can generate value for a firm through the ability to deter entry of new competitors. In this respect, we distinguish between a brand's direct effect on demand and its strategic effect on the behavior of rival firms. We investigate this within the context of the U.S. stacked chips category using a dynamic model tha...

摘要：We study a large-scale (n = 50,000) natural field experiment implemented by the U.S. Social Security Administration aimed at increasing the timely and accurate self-reporting of wages by Supplemental Security Income (SSI) recipients. A letter reminding SSI recipients of their wage reporting responsibilities significantly increased both the likelihood of reporting any earnings and the total earnings reported. However, the specific letter content-providing social information or highlighting the ...

摘要：We examine how brokerage firm initial public offerings (IPOs) influence the research quality of sell-side analysts employed by the brokerage. Our main results focus on earnings forecast bias and absolute forecast errors as proxies for research quality. Using a staggered difference-in-differences analysis, we document significant decreases in forecast bias and absolute forecast error during the two-year period centered on the analysts' brokerage house IPO. In additional analyses, we explore sev...

摘要：Research in psychology shows that consumption goals can help consumers avoid excessive consumption of vice goods and the associated long-term harm. In this paper, we propose a model of self-control with consumption goals and examine how goals moderate the behavior of consumers and the firm's strategy. We find that consumers' personal goals lead to a lower price for a less unhealthy product but a higher price for a more unhealthy product. Furthermore, even though personal goals reduce the sales...

摘要：We construct an economic framework for understanding the incentives of the participants of a permissioned blockchain for supply chains and other related industries. Our study aims to determine whether adoption of blockchain is socially beneficial and whether such adoption arises in equilibrium. We find that blockchain reduces information asymmetry for consumers, thereby enhancing consumer welfare. Consumer welfare gains can be suffi-ciently large that blockchain adoption is socially beneficial...

摘要：Cold start describes a commonly recognized challenge for online advertising platforms: with limited data, the machine learning system cannot accurately estimate the click-through rates (CTR) of new ads and, in turn, cannot efficiently price these new ads or match them with platform users. Traditional cold start algorithms often focus on improving the learning rates of CTR for new ads to improve short-term revenue, but unsuccessful cold start can prompt advertisers to leave the platform, decrea...

摘要：In the ranking and selection problem, a sampling budget is allocated among a finite number of designs with the goal of efficiently identifying the best. Allocations of this budget may be static (with no dependence on the random values of the samples) or adaptive (decisions are made based on the results of previous decisions). A popular methodological strategy in the simulation literature is to first characterize optimal static allocations by using large deviations theory to derive a set of opt...

摘要：Institutional investors' proxy voting decisions are influenced by their neighbors. I identify peer effects in proxy voting using close-call votes on shareholder-sponsored governance proposals at publicly traded financial institutions (focal institutions). I first show that the passage of a governance proposal at a focal institution makes the institution more likely to vote against management at its portfolio firms. Using a triple-difference approach, I find that the neighboring institutions of...

摘要：We investigate the effects of a tick-size reduction on market quality in a multi-period limit order book market. For illiquid stocks, reducing the tick size facilitates under-cutting and discourages liquidity provision, resulting in deteriorating market quality but higher volume. For liquid stocks, reducing the tick size curtails queues, resulting in lower depth and volume but narrower spread. With a competing crossing network, a tick-size reduction results in worse market quality for all stoc...
