We show that the largest increase in unemployment benefits in U.S. history had large spending impacts and small job-finding impacts. This finding has three implications. First, increased benefits were important for explaining aggregate spending dynamics--but not employment dynamics--during the...

An impulse response is the dynamic average effect of an intervention across horizons. We use the well-known Kitagawa-Blinder-Oaxaca decomposition to explore a response's heterogeneity over time and over states of the economy. This can be implemented with a simple extension to the usual local...

In the past decade, a new paradigm for fiscal and monetary policy analysis has emerged, combining the canonical macro model of income and wealth inequality with the New Keynesian model. These Heterogeneous-Agent New Keynesian ("HANK") models feature new transmission channels and allow for the...

We analyze whether government spending multipliers differ by the sign of the shock. Using aggregate historical U.S. data, we apply Ben Zeev's (2020) nonlinear diagnostic tests and find evidence of nonlinearities in the impulse response functions of both government spending and GDP. We then...

A large literature has documented that fiscal policy is procyclical in emerging markets and developing economies and acyclical/countercyclical in advanced economies. This paper analyzes fiscal procyclicality in commodity-exporting countries. It first shows that the degree of fiscal...

We build a tractable New Keynesian model to jointly study four types of monetary and fiscal policy. We find quantitative easing (QE), lump-sum fiscal transfers, and government spending have the same effects on the aggregate economy when fiscal policy is fully tax financed. Compared with these...

We estimate the effects of government spending along the supply chain using disaggregated U.S. government procurement data. We first identify sectoral public spending shocks and combine them with input-output tables to measure upstream and downstream exposure through the production network. We...

This paper studies the economic impacts of carbon pricing. Exploiting institutional features of the European carbon market and high-frequency data, I document that a tighter carbon pricing regime leads to higher energy prices, lower emissions and more green innovation. This comes at the cost of...

This paper investigates the impact of carbon pricing on the economy, with a focus on European carbon taxes and the carbon market. Our analysis reveals three key findings. First, while both policies have successfully reduced emissions, the economic costs of the European carbon market are larger...

Fiscal policy in the U.S. and other countries renders intertemporal budgets non-differentiable, nonconvex, and discontinuous. Consequently, assessing work and saving responses to policy requires global optimization. This paper develops the Global Life-Cycle Optimizer (GLO), a stochastic...
