Competition And Innovation: The Breakup Of Ig Farben, Felix Poege
Competition And Innovation: The Breakup Of Ig Farben, Felix Poege
Faculty Scholarship
The relationship between competition and innovation is difficult to disentangle, as exogenous variation in market structure is rare. The 1952 breakup of Germany’s leading chemical company, IG Farben, represents such a disruption. After the Second World War, the Allies occupying Germany imposed the breakup because of IG Farben’s importance for the German war economy instead of standard antitrust concerns. In technology areas where the breakup reduced concentration, patenting increased strongly, driven by domestic firms unrelated to IG Farben. An analysis of patent texts shows that an increased propensity to patent does not drive the effect. Descriptively, IG Farben’s successors increased …

Industry concentration has been rising in the US since 1980. Does this signal declining competition and need for a new antitrust policy? Or are other factors causing concentration to rise? This paper explores the role of proprietary information technology (IT), which could increase the productivity of top firms relative to others and raise their market share. Instrumental variable estimates find a strong link between proprietary IT and rising industry concentration, accounting for much of its growth. Moreover, the top four firms in each industry benefit disproportionately. Large investments in proprietary software—$250 billion per year—appear to significantly impact industry structure.
The Policy Challenge Of Artificial Intelligence, James Bessen
The Policy Challenge Of Artificial Intelligence, James Bessen
Faculty Scholarship
New "artificial intelligence" (AI) technology promises to bring dramatic social and economic changes, demanding major policy changes. In intellectual property and antitrust law, AI will exacerbate a damaging trend: across all major sectors of the economy, proprietary information technology is increasing the market dominance of large firms. This trend might not seem like bad news, but it is evidence of a slowdown in the spread of technical knowledge throughout the economy. The result is rising industry concentration, slower productivity growth and growing wage inequality. The key challenge to IP and antitrust policy will be counter this trend yet maintain innovation …
