“…39 To be sure, such broad industry measures of concentration do not represent antitrust markets in the sense of competition law. E.g., see Shapiro (2018) and Werden and Froeb (2018a). Even so, the economic factors that have propelled the emergence of superstar firms are the same that also facilitate the emergence of concentration in antitrust markets.…”

“…However, as is demonstrated in Werden and Froeb (), these industry‐level measurements need not be coincident with the “markets” that are relevant for antitrust purposes. In the geographic dimension, the relevant markets might be local or regional, rather than national; or they might be international, rather than national.…”

This paper extends earlier data series on aggregate concentration in the U.S. economy—the percentage of aggregate economic activity that could be attributed to the largest “X” companies—into the first two decades of the twenty‐first century. We find that there has been a moderate but continued increase in aggregate concentration since the mid‐1990s. This increase appears in data on employment and payrolls that have been compiled by the U.S. Bureau of the Census, as well as employment and profits data that are drawn from the annual “Fortune 500” lists. This increase does not, however, appear to have raised aggregate concentration above the levels of the early 1980s. (JEL L10, L11, L19)

“…That it should focus on localities of homogenous product markets where market delineation is properly defined. Only in such instances can market shares be scrutinised to conclude market power (Coate & Fischer, 2008; Werden & Froeb, 2018; Werden, 2013; Wright, 2018). In contrast, another view contends that these metrics do provide insights about the extent of market power enjoyed by industrial oligopolies, although not so much nationwide (Shapiro, 2019).…”

This paper documents the evolution of markups and concentration, detects causality between firm churning and markups/concentration, and determines the impact of fixed costs on markups. It relies on production data of Eswatini during 1994–2007 to estimate markups using the production approach. It finds elasticities, markups and concentration to be comparable with other findings elsewhere. Although no causality is found from a regression of markups/concentration to entry/exit dynamics an increase in productivity within high capital stock industries and in fixed costs raises average markups. Further research will focus on markup state dependence, unobserved heterogeneity, and endogenous regime switching to enhance understanding of markup pricing.
