  摘要：In this paper, we examine the effects of the cry-wolf syndrome in a setting where a manufacturer hires a forecaster to make a recommendation on the capacity decision. In this context, we define cry wolf as a behavioral syndrome in which the manufacturer becomes less compliant with a forecaster's valuable recommendation after the forecaster's prior recommendation is known to be ex post nonoptimal. We find that, although the cry-wolf syndrome unequivocally leads to lower performance for the manu...
• Dynamic stochastic lot sizing with forecast evolution in rolling-horizon planning AI翻译

  摘要：Academic approaches considering demand uncertainty in lot sizing are seldom used in practice. Industry typically implements deterministic models and accounts for uncertainties by using a rolling-horizon planning framework with frequent forecast updates. This paper bridges this gap by proposing a stochastic lot-sizing methodology adapted to rolling-horizon processes. Using the martingale model of forecast evolution (MMFE), we are able to anticipate the forecast updates from rolling-horizon plan...
• Optimal specialty crop planning policies with yield learning and forward contract AI翻译

  摘要：Hops are the flowers of a specialty crop that provide unique flavors to craft beer. We study a multi-year crop planning problem for a farmer who seeks to add hops production to the current production of a conventional crop. The farmer must dynamically determine the number of acres to allocate to each crop and design the terms of the forward contract under which brewers purchase the hops, considering the uncertainty of weather conditions, hops yield, hops spot market price, and conventional cro...
• Peer-to-peer sharing platforms with quality differentiation: Manufacturer's strategic decision under sharing economy AI翻译

  摘要：As peer-to-peer sharing platforms emerge in the downstream market, upstream product manufacturers may build their exclusive sharing platform, seeking benefits from the sharing market. To study the profit and welfare implications of the emergence of sharing economy and manufacturer's platform-building strategy, we employ a vertically differentiated duopoly setting and consider three scenarios: no-sharing benchmark, a single third-party platform emerged, and manufacturer-built platform co-existi...
• Competitive multiproduct contracting under multinomial logit demand AI翻译
  作者：Shao, Lusheng

  摘要：Despite the prevalence of multiproduct firms in many industries, the supply chain contracting literature has predominantly focused on problems where an upstream player offers only one product. This paper studies multiproduct contract design for competing manufacturers each with several products to sell via a common retailer. We consider two contracting schemes under multinomial logit demand (MNL): individual contracting, in which the manufacturers set a wholesale price for each of their produc...
• Tracking disclosure change trajectories for financial fraud detection AI翻译

  摘要：The global economic disruption brought by COVID-19 crisis can set a stage for the prevalence of financial statement frauds, which jeopardize the efficient functioning of capital markets. In this paper, we propose a nuanced method to detect frauds by tracking granular changes in disclosures over time. Specifically, we first align paragraphs between consecutive disclosures by their similarities. This alignment can be solved as an optimization-based matching problem. Then we identify three types ...
• New product life cycle curve modeling and forecasting with product attributes and promotion: A Bayesian functional approach AI翻译

  摘要：New products are highly valued by manufacturers and retailers due to their vital role in revenue generation. Product life cycle (PLC) curves often vary by their shapes and are complicated by promotional activities that induce spiky and irregular behaviors. We collaborate with JD.com to develop a flexible PLC curve forecasting framework based on Bayesian functional regression that accounts for useful covariate information, including product attributes and promotion. The functional model treats ...
• Post-promotion redemption, exposure, and spillover effects of electronic coupons: An empirical analysis AI翻译

  摘要：Coupon promotions have been increasingly used with the development of electronic commerce technologies. The post-promotion effects of coupon promotions have been mixed. Using a randomly selected customer sample at a firm that operates a large online classified ads website, we examine the exposure, redemption, and spillover effects of coupon promotions. We find a negative exposure effect and a positive redemption effect. For customers who received coupons but did not redeem them (i.e., exposure...
