Since the 1980s, the United States has regressed to a level of economic inequality not seen since the Gilded Age in the late nineteenth century. At the same time, technological innovation has transformed society, and a core priority of public policy has been promoting innovation. What is the relationship between economic inequality and technological change?

Mordecai Kurz introduces a comprehensive integrated theory of the dynamics of market power and income inequality. He shows that technological innovations are not simply sources of growth and progress: they sow the seeds of market power. In a free market economy with intellectual property rights, firms’ control over technology enables them to expand, attain monopoly power, and earn exorbitant profits. Competition among innovators does not eliminate market power because technological competition is different from standard competition; it results in only one or two winners. Kurz provides a pioneering analysis grounded on quantifying technological market power and its effects on inequality, innovation, and economic growth. He outlines what causes market power to rise and fall and details its macroeconomic and distributional consequences.

Kurz demonstrates that technological market power tends to rise with new innovations to extremely high levels, increasing inequality of income and wealth. Unchecked inequality threatens the foundations of democracy: public policy is the only counterbalancing force that can restrain corporate power, attain more egalitarian distribution of wealth, and make democracy compatible with capitalism. Kurz offers proposals to redress inequality by restricting corporate mergers and acquisitions, reforming patent law, improving the balance of power in the labor market, increasing taxation, promoting upward mobility, and stabilizing the middle class.

Time will be allocated for Q&A.

"Starting with the simple idea that established firms can use their technological innovations to deter entry, Kurz constructs an account of the rise in wealth inequality in modern societies. Beautifully blending analytical reasoning with empirical evidence, the book offers a picture of contemporary macroeconomic growth and development that is at once novel and convincing. This is economics at its best" Sir Partha DasguptaUniversity of Cambridge
