摘要：This paper examines the effect of the expiry of recording copyright on the supply of music???in the form of rereleases, availability on streaming platforms, and concert performances???by artists popular in the United Kingdom in the 1960s. We find that recording copyright expiry has different effects on a song???s availability in different distribution channels. The lapsing of copyright leads to a large increase in the number of rereleases in physical formats, holding constant artist, age, and ...

摘要：Clinical practice guidelines do not sufficiently address the needs of patients with chronic conditions as these guidelines focus on single disease management and ignore unique patient-specific conditions. As a result, a nonpersonalized approach to the management of the patients with chronic conditions leads to adverse events and increases the financial burden on the healthcare system as over 150 million Americans experience chronic conditions. To this end, we develop a stochastic modeling fram...

摘要：Several corporations have committed to procuring a percentage of their electricity demand from renewable sources by a future date. Long-term financial contracts with renewable generators based on a fixed strike price, known as virtual power purchase agreements (VPPAs), are popular to meet such a target. We formulate rolling power purchases using a portfolio of VPPAs as a Markov decision process, accounting for uncertainty in generator availability and in the prices of electricity, renewable en...

摘要：Dynamic structures in intertemporal choices offer multiple channels through which reference dependence can occur. We examine intertemporal reference dependence when using choice lists to elicit time preference over outcome sequences. Reference point effects can arise endogenously within an outcome sequence and exogenously from the experimental environment of the choice list. We show that estimated discount factors in the choice list are biased by both kinds of reference points and propose a mo...

摘要：Despite the substantial economic impact of the restaurant industry, large-scale empirical research on restaurant survival has been sparse. We investigate whether consumer-posted photos can serve as a leading indicator of restaurant survival above and beyond reviews, firm characteristics, competitive landscape, and macroconditions. We employ machine learning techniques to extract features from 755,758 photos and 1,121,069 reviews posted on Yelp between 2004 and 2015 for 17,719 U.S. restaurants....

摘要：This paper studies outcomes of the deferred acceptance algorithm in large random matching markets where priorities are generated either by a single lottery or by independent lotteries. In contrast to prior work, my model permits students to submit lists of varying lengths and schools to vary in their popularity and number of seats. In a limiting regime where the number of students and schools grow while the length of student lists and number of seats at each school remain bounded, I provide ex...
