摘要:
Major innovations often arrive first as high-priced luxuries for the rich and only later become affordable necessities for the poor. Using barcode-level data from the NielsenIQ Homescan Consumer Panel linked to firm-level accounts and patent records from PatentsView, this paper provides evidence on this process and develops a unified framework that connects income inequality, the allocation of innovative effort, and long-run growth. Empirically, we show that within narrowly defined product markets, prices decline over the product life cycle while the spending share of low-income households rises; that firms whose sales are tilted toward richer consumers display much higher patenting per dollar of revenue, in both counts and claim-weighted measures; and that diffusion toward poorer buyers is accompanied by firm entry and declining market concentration. We then build a dynamic general equilibrium model with hierarchical consumption and endogenous firm dynamics that rationalizes these patterns and delivers a new misallocation channel: rising inequality shifts and concentrates R&D toward luxury goods and rich-oriented firms, leaving productivity gains in basic goods underexploited and reducing the contribution of innovation to aggregate growth. Calibrating the model based on U.S. scanner and patent data, we find that the increase in income inequality between the 1970s and the 2010s can almost fully account for the concurrent slowdown in per-capita GDP growth.

摘要:
This study examines the impact of fatal police encounters on municipal borrowing costs in the United States. Using a bond-level dataset between 2000 and 2019, we link county-level fatal encounters with municipal bond offering yield spreads. To address endogeneity, we implement a two-stage least squares (2SLS) strategy using a constructed instrument based on national military surplus and local proximity to disposition facilities. We find that fatal encounters, particularly those attracting substantial media coverage, significantly increase municipal borrowing costs, with the largest effects for severe incidents and in contexts where investors perceive heightened local fiscal stress. Mechanism tests show that the widening spreads operate through (i) fiscal stress from settlements and higher law enforcement expenditures, (ii) governance and stewardship, with weakened oversight elevating perceived default risk, and (iii) social disruption amplified by local investor exposure, as unrest and local economic spillovers affect predominantly local bondholders. Our results reveal that lapses in governance and social order carry measurable financial costs, linking social shocks directly to capital markets.
