If further decarbonization of electricity systems is to continue, a next generation of innovation in transformative grid modernization and renewables integration technologies will be needed. Few studies have investigated the policy determinants of innovation in this sector to glean insights on...

This paper provides a primer on the economics of environmental innovation. Our intention is not to write a pure review paper, but to also provide an up-to-date textbook treatment on the issue. Thus, we start by defining the marginal costs of both emissions and of emissions abatement. We then...

The costs of low-carbon energy fell dramatically over the past decade, leading to rapid growth in its deployment. However, many challenges remain to deploy low-carbon energy at a scale necessary to meet net zero carbon emission targets. If net zero goals are to be met, developing complementary...

Shared socioeconomic pathways (SSPs) are perhaps the most influential economic policy analyses today. My paper evaluates their development, natural associations, logical consequences, and economic identification. All five SSP baseline scenarios are predicting scenarios that historical...

We study the private adoption and diffusion of a technology that provides a local public good - PurpleAir (PA) pollution monitors. From a purely informational perspective, the ideal spacing of these monitors should reflect the degree of spatial correlation in pollution. In stark contrast, we...

This paper shows that large, multi-establishment business enterprises face a high cost of middle management in poor countries and that this cost inhibits the growth of the modern sector. We provide new empirical evidence using a database covering compensation for 300,000 middle managers working...

What explains record U.S. house price growth since late 2019? We show that the shift to remote work explains over one half of the 23.8 percent national house price increase over this period. Using variation in remote work exposure across U.S. metropolitan areas we estimate that an additional...

We examine friendships and study partnerships among university students over several years. At the aggregate level, connections increase over time, but homophily on gender and ethnicity is relatively constant across time, university residences, and different network layers. At the individual...

We show that supply networks are inefficiently, and insufficiently, resilient. Upstream firms can expand their production capacity to hedge against supply and demand shocks. But the social benefits of such investments are not internalized due to market power and market incompleteness. Upstream...

Network diffusion models are used to study things like disease transmission, information spread, and technology adoption. However, small amounts of mismeasurement are extremely likely in the networks constructed to operationalize these models. We show that estimates of diffusions are highly...
