Does investing in information technology (IT) enable firms to “scale without mass” and increase their market share? In a new paper, Erik Brynjolfsson, Wang Jin, and Xiupeng Wang examine how IT affects firm size, market concentration, and the labor share of revenue.

New research indicates that FinTech lending has not been as ‘disruptive’ in risk-based pricing as claimed.

In two recent papers, Matthew E. Kahn and Joseph Tracy examine the outcomes of local labor markets affected by monopsony power. They find that in areas with a high degree of monopsony power, workers earn lower wages but are compensated with lower house prices, at the expense of homeowners. Monopsony markets also experience a “brain drain” over time due to young, educated workers who leave for better opportunities. The rise of work-from-home may accelerate this dynamic by allowing talent to change labor markets without changing residences.

Income inequality may exacerbate the spread of infectious diseases. In a new paper, Jay Bhattacharya, Joydeep Bhattacharya, and Min Kyong Kim examine the relationship between income inequality and the incidence and prevalence of tuberculosis across countries.

Darren Bush, Mark Glick, and Gabriel A. Lozada argue that the Consumer Welfare Standard  is inconsistent with modern welfare economics and that a modern approach to antitrust could integrate traditional Congressional goals as advocated by the Neo-Brandesians.
