Network Structure and the Efficiency Gains from Mergers: Evidence from U.S. Freight Railroads

The RAND Journal of Economics, EarlyView.
ABSTRACT The trade‐off between market power and efficiency gains is central to antitrust analyses of mergers, but empirical evidence quantifying efficiencies remains limited. Using transaction‐level data from U.S. freight railroads (1985–2005), this article quantifies merger‐induced cost efficiencies, driven mainly by eliminating inter‐railroad ...

The Impact of Autonomous Truck Technology on US Interstate Trade

Journal of Regional Science, EarlyView.
ABSTRACT Recent advances in autonomous and semi‐autonomous vehicle technologies promise substantial cost savings for goods shipped by truck. In this study, we quantify the impacts of these transport cost reductions on the US interstate trade using a structural gravity model of domestic trade. Based on projected cost savings from the widespread adoption

Responsible Innovation Management in Profit‐Driven Firms: A Cross‐Cultural Analysis in Germany, India, and Japan

Journal of Product Innovation Management, EarlyView.
ABSTRACT Responsible innovation (RI) challenges profit‐driven firms to reconcile market pressures with societal and environmental responsibilities. We ask how firms integrate anticipation, reflexivity, inclusion, and responsiveness (ARIR) into responsible innovation management (RIM), and how national context and cultural dimensions shape the degree and
