李善友：“有病的人”去创业

“作为一个在黑土地出生的农家少年，从南开数学到HR，再到总编辑，继而创业，现今又迈入我视为终身事业的教育领域，梦想一次又一次幸运地照进我平凡的现实。”李善友说道。他的朋友这么形容李善友，他拼命抓住一切可能的机会，把困难当成“学习和锻炼的良机，愈挫愈奋，越战越勇”。     

Optimal search,learning and implementation

We characterize the incentive compatible, constrained efficient policy (“second-best”) in a dynamic matching environment, where impatient, privately informed agents arrive over time, and where the designer gradually learns about the distribution of agents? values. We also derive conditions on the learning process ensuring that the complete-information, dynamically efficient allocation of resources (“first-best”) is incentive compatible. Our analysis reveals and exploits close, formal relations between the problem of ensuring implementable allocation rules in our dynamic allocation problems with incomplete information and learning, and between the classical problem, posed by Rothschild (1974) [20], of finding optimal stopping policies for search that are characterized by a reservation price property.     

An intelligent tutoring system for the accounting cycle: Enhancing textbook homework with artificial intelligence

This paper describes an electronic tutoring system, developed using principles of artificial intelligence (AI), to help students learn the accounting cycle. Unlike other educational technologies, the tutoring system provides instruction and feedback that is tailored to each individual student and addresses not only problem-solving outcomes but also problem-solving processes. To assess the effectiveness of the tutoring system, we administered a pre-test and then required students in a sophomore accounting course to use either the tutoring system or their textbook as a reference when journalizing transactions for a homework assignment. We then administered a post-test. A pre-post analysis showed that the tutor group’s test performance increased approximately 27% points, whereas the textbook group’s test performance improved by only 8% points. Implications of these findings for instructors and researchers are discussed.     

Resale Markets and the Assignment of Property Rights

The consumption of an indivisible good causes identity-dependent externalities to non-consumers. We analyse resale markets where the current owner designs the trading procedure, but cannot commit to future actions. We ask the following questions: (1) Does the identity of the initial owner matter for the determination of the final consumer? (2) Is the outcome always efficient? The major conclusion of our paper is that the irrelevance of the initial structure of property rights arises in resale processes even if there are transaction costs that hinder efficiency. This result complements the Coasian view where the irrelevance of the assignment of property rights is a consequence of efficiency.     

When the going gets tough,do the tough go shopping?

This study examines the impacts of consumer confidence on stockpiling behavior and, subsequently, retail inventory management. We show how stockpiling behavior evolved during the “Great Recession” of 2008–2009 as consumer confidence waned and demonstrate the impact of this development on inventory management. Drawing on the two-segment household inventory theory consisting of nonstockpiling and stockpiling segments, we use a panel dataset (2005–2015) to calibrate household inventory holdings. This dataset then serves as input for a retailer-level case study. Our empirical analysis reveals significant impacts from changing stockpiling behavior. When consumer confidence is low, both stockpiling and nonstockpiling segments respond by reducing weekly consumption rates; however, the stockpiling segment also significantly lengthens the time between shopping trips, and ultimately increases the duration of inventory holdings. These changes to consumption and stockpiling add complexity to inventory planning, requiring retailers to carefully adjust inventory levels to maintain service levels.
