The paper describes a semistructural macrofiscal approach to simulating and forecasting macroeconomic policies. Our canonical model is adapted to Cambodia and we demonstrate its application with an illustrative scenario of macroeconomic effects of the Covid-19 pandemic. Complemented with...

We provide evidence that industries' supply curves are convex. To guide our empirical analysis, we develop a model, in which capacity constraints at the plant level generate convex supply curves at the industry level. The industry's capacity utilization rate is a sufficient statistic for the...

Financial intermediaries issue the majority of liquid securities, and nonfinancial firms have become net savers, holding intermediaries' debt as cash. This paper shows that intermediaries' liquidity creation stimulates growth -- firms hold their debt for unhedgeable investment needs -- but also...

We study Ramsey-optimal fiscal policy in an economy in which product varieties are the result of forward-looking investment decisions by firms. There are two main results. First, depending on the particular form of variety aggregation in preferences, firms' dividend payments may be either...

L’effet de la dette publique sur l’investissement privé est théoriquement indéterminé. Ce lien peut aussi bien être négatif (debt overhang, effet d’éviction) que positif (effet accélérateur sur la croissance économique et donc sur l’investissement privé). Notre étude consiste...

This paper explores different fiscal stimuli within a business cycle model with an endogenous mass of firms which we estimate for the U.S. economy using Bayesian techniques. We demonstrate that a changing mass of firms is a crucial dimension for evaluating fiscal policy since it can both...

We estimate how durable expenditures respond to government spending shocks at different points in the business cycle using a nonlinear VAR approach that allows for the durable multiplier to vary smoothly with the state of the economy. We find strong evidence that the aggregate durable spending...

We study Ramsey-optimal fiscal policy in an economy in which product varieties are the result of forward-looking investment decisions by firms. There are two main results. First, depending on the particular form of variety aggregation in preferences, firms' dividend payments may be either...

The sensitivity of U.S. aggregate investment to shocks is procyclical: the response upon impact increases by approximately 50% from the trough to the peak of the business cycle. This feature of the data follows naturally from a DSGE model with lumpy microeconomic capital adjustment. Beyond...

Microeconomic lumpiness matters for macroeconomics. According to our DSGE model, it explains roughly 60% of the smoothing in the investment response to aggregate shocks. The remaining 40% is explained by general equilibrium forces. The central role played by micro frictions for aggregate...
