On Spatial Point Processes With Composition‐Valued Marks

International Statistical Review, EarlyView.
Summary Methods for marked spatial point processes with scalar marks have seen extensive development in recent years. While the impressive progress in data collection and storage capacities has yielded an immense increase in spatial point process data with highly challenging non‐scalar marks, methods for their analysis are not equally well developed ...

Shock Propagation within Multisector Firms

Journal of Money, Credit and Banking, EarlyView.
Abstract This paper studies the role of multisector firms in the cross‐sectoral propagation of economic shocks. By leveraging an increase in import competition from China as a source of a negative economic shock, we show that employment of an establishment in a given industry is negatively affected by shocks that impact establishments operating in ...

Optimal Simple Ratings

The Journal of Industrial Economics, EarlyView.
ABSTRACT We study optimal simple rating systems that partition sellers into a finite number of tiers. We show that optimal ratings must be threshold partitions, and that for linear supply and Cournot competition with constant marginal cost, optimal thresholds solve a k‐means clustering problem requiring only the quality distribution.

RPM and Vertical Integration With Upstream Competition and Noncontractible Efforts

The Journal of Industrial Economics, EarlyView.
ABSTRACT We study RPM and vertical integration in a common agency setting with two differentiated manufacturers and one retailer, where consumer demand depends on both the manufacturers' and retailer's noncontractible efforts. Under vertical separation, the adoption of maximum RPM by both manufacturers is an equilibrium and intensifies competition ...
