Pandemic Control in ECON-EPI Networks
We develop an ECON-EPI network model to evaluate policies designed to improve health and economic outcomes during a pandemic. Relative to the standard epidemiological SIR set-up, we explicitly model social contacts among individuals and allow for heterogeneity in their number and stability. In addition, we embed the network in a structural economic model describing how contacts generate economic activity. We calibrate it to the New York metro area during the 2020 COVID-19 crisis and show three main results. First, the ECON-EPI network implies patterns of infections that better match the data ...

Macroeconomic Volatility and External Imbalances
Does macroeconomic volatility/uncertainty affect accumulation of net foreign assets? In OECD economies over the period 1970-2012, changes in country specific aggregate volatility are, after controlling for a wide array of factors, significantly positively associated with net foreign asset position. An increase in volatility (measured as the standard deviation of GDP growth) of 0.5% over period of 10 years is associated with an increase in the net foreign assets of around 8% of GDP. A standard open economy model with time varying aggregate uncertainty can quantitatively account for this ...

Germs, Social Networks, and Growth
Does the pattern of social connections between individuals matter for macroeconomic outcomes? If so, where do these differences come from and how large are their effects? Using network analysis tools, we explore how different social network structures affect technology diffusion and thereby a country's rate of growth. The correlation between high-diffusion networks and income is strongly positive. But when we use a model to isolate the effect of a change in social networks, the effect can be positive, negative, or zero. The reason is that networks diffuse ideas and disease. Low-diffusion ...

The End of the American Dream? Inequality and Segregation in US Cities
Since the 1980s, the US has experienced not only a steady increase in income inequality, but also a contemporaneous rise in residential segregation by income. What is the relationship between inequality and residential segregation? How does it affect intergenerational mobility? We first document a positive correlation between inequality and segregation, both over time and across metro areas. We then develop a general equilibrium model where parents choose the neighborhood where they raise their children and invest in their children’s education. In the model, segregation and inequality ...

Nature or nurture? learning and female labor force dynamics
In the last century, the evolution of female labor force participation has been S-shaped: It rose slowly at first, then quickly, and has leveled off recently. Central to this dramatic rise has been the entry of women with young children. We argue that this S-shaped dynamic came from generations of women learning about the relative importance of nature (endowed ability) and nurture (time spent child-rearing) in determining children's outcomes. Each generation updates the beliefs of their parents, by observing others' outcomes. When few women participate in the labor force, most outcomes are ...

Culture: an empirical investigation of beliefs, work, and fertility
We study the effect of culture on important economic outcomes by using the 1970 census to examine the work and fertility behavior of women born in the U.S. but whose parents were born elsewhere. We use past female labor force participation and total fertility rates from the country of ancestry as our cultural proxies. These variables should capture, in addition to past economic and institutional conditions, the beliefs commonly held about the role of women in society (i.e., culture). Given the different time and place, only the beliefs embodied in the cultural proxies should be potentially ...
