There is substantial disagreement about the consequences of the Tax Cuts and Jobs Act (TCJA) of 2017, which constitutes the most extensive tax reform in the United States in more than 30 years. Using a large-scale two-country dynamic general equilibrium model with nominal rigidities, the authors...

There is substantial disagreement about the consequences of the Tax Cuts and Jobs Act (TCJA) of 2017, which constitutes the most extensive tax reform in the United States in more than 30 years. Using a large-scale two-country dynamic general equilibrium model with nominal rigidities, we find...

Against the backdrop of elevated model uncertainty in DSGE models with a detailed modeling of financial intermediaries, we investigate the performance of optimized macroprudential policy rules within and across models. Using three canonical banking DSGE models as a representative sample, we show...

For some time now, structural macroeconomic models used at central banks have been predominantly New Keynesian DSGE models featuring nominal rigidities and forwardlooking decision-making. While these features are widely deemed crucial for policy evaluation exercises, most central banks have...

We analyze the influence of monetary policy on firms' extensive margin and productivity. Our empirical evidence for the U.S. based on a macro-financial SVAR suggests that expansionary monetary policy shocks stimulate corporate profits, reduce firm exit and increase firm entry. In the medium run,...

This paper analyses the joint long-run evolution of wealth and income inequality. We show that top wealth and income shares were cointegrated over the past century in France and the US. We rationalise this finding using a two-agent version of the Solow growth model. In this framework, the...

We show that if business cycles are driven by financial shocks, the interplay between the effective lower bound (ELB) and the costs of external financing can generate an additional supply-side channel, which causes a disconnect between inflation and output. In normal times, factor costs dominate...

We estimate the long- and short-run relationship between top income and wealth shares for France and the US since 1913. We find strong evidence for a long-run cointegration relationship governed by relative saving rates at the top. For both countries, we estimate a decline in the relative saving...

This paper proposes a tractable financial accelerator New Keynesian DSGE modelthat allows for closed-form solutions. In the presence of financial frictions, theNew Keynesian Phillips curve features a flat slope with respect to the output gapand is strongly forward-looking. All shocks cause...

The recently observed disconnect between inflation and economic activity can be explained by the interplay between the zero lower bound (ZLB) and the costs of external financing. In normal times, credit spreads and the nominal interest rate balance out; factor costs dominate firms' marginal...
