We use an analytically tractable heterogeneous-agent (HANK) version of the standard New Keynesian model to show how the size of fiscal multipliers depends on i) the distribution of factor incomes, and ii) the source of nominal rigidities. With sticky prices but flexible wages, the standard...

We argue that a 2-agent version of the standard New Keynesian model--where a "worker" receives only labor income and a "capitalist" only profit income-- offers insights about how income inequality affects the monetary transmission mechanism. Under rigid prices, monetary policy affects the...

We formulate an economic time use model and add to it an epidemiological SIR block. In the event of an epidemic, households shift their leisure time from activities with a high degree of social interaction to activities with less, and also choose to work more from home. Our model highlights the...

The economic effects of climate change vary across both time and space. To study these effects, this paper builds a global economy-climate model featuring a high degree of geographic resolution. Carbon emissions from the use of energy in production increase the Earth's (average) temperature and...

We build a three-state general equilibrium model of the aggregate labor market that features both standard labor supply forces and labor market frictions. Our model matches key features of the cyclical properties of employment, unemployment, and nonparticipation as well as those of gross worker...

Developing countries employ a very large share of their workforce in agriculture, a sector in which their labor productivity is particularly low. We take a macroeconomic approach to analyze the role of agriculture in development. We construct a new database with systematic measures of inputs and...

A production efficiency perspective naturally leads to the prescription that more productive individuals should work more than less productive individuals. Yet, systematic differences in actual hours worked across high- and low-wage individuals are barely noticeable. We highlight that the...

What explains how much people work? Going back in time, a main fact to address is the steady reduction in hours worked. The long-run data, for the U.S. as well as for other countries, show a striking pattern whereby hours worked fall steadily by a little below a half of a percent per year,...

We estimate an aggregate production function with constant elasticity of substitution between energy and a capital/labor composite using U.S. data. The implied measure of energy-saving technical change appears to respond strongly to the oil-price shocks in the 1970s and has a negative medium-run...

A labor market with search and matching frictions, where wage setting is controlled by a monopoly union that follows a norm of wage solidarity, is found vulnerable to substantial distortions associated with holdup. With full commitment to future wages, the union achieves efficient hiring in the...
