1. Increased Concentration Concentration
1. Increased Concentration Concentration has increased in most sectors—the original CEA list Note: * indicates that the percentage point change is calculated using only taxable firms in that industry, as its 1997 revenue share data are only available for the 50 largest taxable firms and the 50 largest tax-exempt firms as separate categories, rather than for all firms combined. Performing this same calculation using data for only tax-exempt firms results in two additional industries showing a decline in concentration (Arts, Entertainment and Recreation, and Educational Services) , while one shows a slight uptick (Other Services). Source: Council of Economic Advisers (2016).
1. Increased Concentration Numerous academic papers have documented increase in concentration in industry data • “In the last two decades, over 75% of U.S. industries have experienced an increase in concentration levels” based on NAICS 3-digit industry (Grullon, Larkin and Michaely 2018) • Increase in CR4, CR20 and HHI for sales and employment has trended up, especially for sales, based on 676 industries of which 388 are in manufacturing (Autor et al. 2017) • Weighted average CR8 has increased both in manufacturing and non-manufacturing as has the HHI for Compustat firms (Gutiérrez and Philippon 2018) • Increase in mean and median CR4, CR8, CR20, and CR50 across 750 industries in Census data (Barkai 2017)
1. Increased Concentration Consistent with findings from numerous IO studies of more well defined markets • Agriculture: Share of revenues held by the top four firms increased between 1972 and 2002 in eight of nine dairy processing and manufacturing industries (Shields 2010) • Appliances: Following Whirlpool-Maytag merger, Herfindahl-Hirschman index (HHI) increased by 800-1,600 for refrigerators, dishwashers, clothes dryers, and clothes washers (Ashenfelter, Hosken, and Weinberg 2013) • Beer: Substantially increased concentration in the beer industry with the HHI increasing from about 1,000 in the mid 1970s to over 4,000 by 2009 (Gokhale and Tremblay 2012) • Fertilizer: Increased Lerner indices of oligopolistic firms from late 1990s/early 2000s to early 2010s (Taylor and Moss 2013) • Financial Services: Loan market share of the top ten commercial banks increased from about 20 percent in 1976 to about 50 percent in 2010 (Corbae and D’Erasmo 2013) • Hospitals: Between the late 1980s and 2006, average HHI across hospital markets increased by about 40 percent to about 3,200, level associated with just three equal-sized competitors in a market (Gaynor, Ho, and Town 2015) • Railroads: Increased market concentration in at least two-thirds of crop reporting districts for four different agricultural commodities between 1985 and 2007 (Prater et al. 2012) • Wireless: Average HHI for wireless providers in a market increased from under 2,500 in 2004 to over 3,100 in 2014 (FCC 2015)
1. Increased Concentration Interpreting greater concentration • Increasing concentration could mean:
1. Increased Concentration Interpreting greater concentration • Increasing concentration could mean: • More competition
1. Increased Concentration Interpreting greater concentration • Increasing concentration could mean: • More competition • OR • Less competition
1. Increased Concentration Potential sources of increased concentration Good/Natural Causes: More competition • Superstar firms • Globalization • Increasing returns to scale and network externalities
1. Increased Concentration Potential sources of increased concentration Good/Natural Causes: More competition • Superstar firms • Globalization • Increasing returns to scale and network externalities • Bad/Unnatural Causes: Less competition • Reductions in merger and antitrust enforcement • Increased regulatory barriers to entry • Increased common ownership??
1. Increased Concentration The retail sector looks a lot like the superstar hypothesis In retail, concentration has increased along with efficiency but markups are unchanged: Source: Crouzet and Eberly (2018)..
1. Increased Concentration The health sector looks much less like the superstar hypothesis Sources: Gaynor (2017) and Fulton (2017).
1. Increased Concentration Macro evidence that on balance the less competition story predominates • At a macro level, the rise of concentration helps explain the decline of the labor share (Barkai 2016) • The evolution of several stylized macro facts like a larger premium on capital can be explained by a calibrated model with a declining neutral rate of interest and reduced competition (Eggertsson et al 2018) • The reduced competition hypothesis survives, albeit in somewhat smaller form, after taking into account the growth of intangibles (Farhi and Guourio 2018) • “Firms in industries with the largest increases in product market concentration have enjoyed higher profit margins, positive abnormal stock returns, and more profitable M&A deals.” (Grullon et al 2016)

2. Introduction to the Expert Panel Our Terms of Reference (excerpt) • “Consider the potential opportunities and challenges the emerging digital economy may pose for competition and pro-competition policy, and to make recommendations on any changes that may be needed… • the impacts of the emergence of a small number of big players in digital markets such as social media, e-commerce, search, and online advertising • appropriate approaches to mergers, takeovers and anticompetitive practices in digital markets • opportunities to enhance competition, to increase business innovation and expand consumer choice • how best to assess consumer impacts in ad-funded products and services that are “free” to consumers.”
