"What’s a Grocery Store? Kroger, Albertsons, and Competion in a Reinvented Industry"

Abstract:

In the face of renewed public interest in antitrust enforcement, two of the largest U.S. supermarket operators announced merger plans in October 2022. The proposed fusion of two companies selling similar arrays of essential products, with over 5,000 stores and 700,000 employees between them, would seem to offer a tempting target for trust busters. But over the past century, the formerly prosaic sector once known as grocery retailing has reinvented itself repeatedly, in ways that will make it difficult for competition authorities even to define a relevant market, much less to quantify the anticipated impact of the merger on prices. Further, structural changes in manufacturing and distribution, notably the diminishing number of independent wholesalers, increasing sales of private brands, and the growing importance of information about customer behavior, may favor concentration in the future regardless of whether this merger proceeds. The paper will evaluate corporate strategies in food retailing over several decades, as well as extensive historical market data, to consider this rapidly changing industry in the context of U.S. antitrust law.

"Deregulation and Market Structure: The Case of Television "

Abstract:

For half a century, a television broadcast license from the Federal Communications Commission was a permit to mint money. Over the past two decades, though, regulatory and technological change have altered the very meaning of “television” and dramatically redistributed rents across the U.S. television industry. Relationships among television stations, broadcast networks, cable and satellite distribution systems, program producers, and viewers have increasingly been shaped by market forces rather than FCC regulations. This deregulation has had significant consequences for industry structure, driving mergers and acquisitions as industry participants have sought to increase their bargaining leverage with respect to one another. This paper will consider the television industry as a case study of how deregulation has disadvantaged small firms and encouraged consolidation throughout the U.S. economy.

"What's a Comparative Advantage?"

Abstract:

Generations of graduate students have studied a concept called “revealed comparative advantage”—basically, the idea that what a country exports shows what it is most efficient at producing. It is hard to find an idea that is more widely accepted among experts. When value chains began to spread around the globe in the late 1980s, they were presumed to be organized on the basis of comparative advantage: the role each country played in producing raw materials, intermediate goods, finished products, and related services such as research and marketing was assumed to reflect the skills of its workforce, the sophistication of its companies, and the depth of its capital markets. The shift of manufacturing out of high-wage countries was said to reflect the comparative advantage of lower-wage countries in labor-intensive activities, while the high-wage countries specialized in what are now referred to as “headquarters activities” in which their highly skilled workers gave them a competitive edge. This paper will argue that the global value chains that undergirded globalization starting in the late 1980s were not mere reflections of comparative advantage. Directly and indirectly, governments aggressively shaped economic geography, providing land and low-cost financing to build factories and distribution centers, offering tax breaks and trade preferences tailored to the desires of specific corporations, and subsidizing transportation and warehousing to hold down the cost of both importing and exporting. These subsidies were critical in determining trade flows and investment patterns. The logical consequence, which economists have been slow to acknowledge, is that globalization reached excessive levels that were not efficient in any economic sense.
