We develop a multi-risk SIR model (MR-SIR) where infection, hospitalization and fatality rates vary between groups—in particular between the “young”, “the middle-aged” and the “old”. Our MR-SIR model enables a tractable quantitative analysis of optimal policy similar to those already developed in the context of the homogeneous-agent SIR models. For baseline parameter values for the COVID-19 pandemic applied to the US, we find that optimal policies differentially targeting risk/age groups significantly outperform optimal uniform policies and most of the gains can be realized by having stricter lockdown policies on the oldest group. For example, for the same economic cost (24.3% decline in GDP), optimal semi–targeted or fully-targeted policies reduce mortality from 1.83% to 0.71% (thus, saving 2.7 million lives) relative to optimal uniform policies. Intuitively, a strict and long lockdown for the most vulnerable group both reduces infections and enables less strict lockdowns for the lower-risk groups. We also study the impacts of social distancing, the matching technology, the expected arrival time of a vaccine, and testing with or without tracing on optimal policies. Overall, targeted policies that are combined with measures that reduce interactions between groups and increase testing and isolation of the infected can minimize both economic losses and deaths in our model.

The lack of reliable electricity in the developing world is widely viewed by policymakers as a major constraint on firm productivity. Yet most empirical studies find modest short-run effects of power outages on firm performance. This paper builds a dynamic macroeconomic model to study the long-run general equilibrium effects of power outages on productivity. The model captures the key features of how firms acquire electricity in the developing world, in particular the rationing of grid electricity and the possibility of self-generated electricity at higher cost. Power outages lower productivity in the model by creating idle resources, by depressing the scale of incumbent firms and by reducing entry of new firms. Consistent with the empirical literature, the model predicts that the short-run partial-equilibrium effects of eliminating outages are small. However, the long-run general-equilibrium effects are many times larger, supporting the view that eliminating outages is an important development objective.

We show a causal impact of immigration on innovation and dynamism in US counties. To identify the causal impact of immigration, we use 130 years of detailed data on migrations from foreign countries to US counties to isolate quasi-random variation in the ancestry composition of US counties that results purely from the interaction of two historical forces: (i) changes over time in the relative attractiveness of different destinations within the US to the average migrant arriving at the time and (ii) the staggered timing of the arrival of migrants from different origin countries. We then use this plausibly exogenous variation in ancestry composition to predict the total number of migrants flowing into each US county in recent decades. We show four main results. First, immigration has a positive impact on innovation, measured by the patenting of local firms. Second, immigration has a positive impact on measures of local economic dynamism. Third, the positive impact of immigration on innovation percolates over space, but spatial spillovers quickly die out with distance. Fourth, the impact of immigration on innovation is stronger for more educated migrants.

We model optimal e-cigarette regulation and estimate key sufficient statistics. Using tax changes and scanner data, we estimate relatively elastic demand and limited substitution between e-cigarettes and combustible cigarettes. In sample surveys, historical smoking declines for high- and low-vaping demographics were unchanged after e-cigarettes were introduced; this demographic shift-share identification also suggests limited substitution. We field a new survey of experts, who report that vaping is almost as harmful as smoking cigarettes. In our model, these results imply that current e-cigarette taxes are far below the social optimum, but Monte Carlo simulations highlight substantial uncertainty.
