Reinventing Retail: The Novel Resurgence of Independent Bookstores

Reinventing Retail: The Novel Resurgence of Independent Bookstores. Ryan Raffaelli, January 20202, Paper, “This study examines how community-based brick-and-mortar retailers can achieve sustained market growth in the face of online and big box retail competition. The appearance of Amazon.com in 1995 led to a significant decline in the number of in- dependent bookstores in the United States, leading many analysts to predict the demise of the sector. However, between 2009 and 2018 independent bookstores proved to be far more resilient than expected. The American Booksellers Association (ABA) reported a 49% percent growth in the number of “indie” booksellers, from 1,651 in 2009 to 2,470 in 2018. This study identifies “3C’s” that contributed to the independent bookstore resurgence…Link

A Compact, Logical Approach to Large-Market Analysis

A Compact, Logical Approach to Large-Market Analysis. Scott Duke Kominers, June 26, 2019, Paper, “In game theory, we often use infinite models to represent “limit” settings, such as markets with a large number of agents or games with a long time horizon. Yet many game-theoretic models incorporate finiteness assumptions that, while introduced for simplicity, play a real role in the analysis. Here, we show how to extend key results from (finite) models of matching, games on graphs, and trading networks to infinite models by way of Logical Compactness, a core result from Propositional Logic. Using Compactness, we prove the existence of man-optimal stable matchings in infinite economies, as well as strategy-proofness of the man-optimal stable matching mechanism. We then use Compactness to eliminate the need for a finite start time in a dynamic matching model. Finally, we use Compactness to prove the existence of both Nash equilibria in infinite games on graphs and Walrasian equilibria in infinite trading networks.Link
