The extraordinary events surrounding the Great Recession have cast a considerable doubt on the traditional sources of macroeconomic instability. In their place, economists have singled out financial and uncertainty shocks as potentially important drivers of economic fluctuations. Empirically...

What accounts for inflation after 2008? We use the prominent pre-crisis Smets-Wouters (2007) model to address this question. We find that due to price markup shocks alone inflation would have been 1% higher than observed and 0.5% higher that the long-run average. Their standard deviation is...

In the data, prices change both temporarily and permanently. Standard Calvo models focus on permanent price changes and take one of two shortcuts when confronted with the data: drop temporary changes from the data or leave them in and treat them as permanent. We provide a menu cost model that...

Major changes have taken place in the U.S. economy within the past quarter century. Changes with implications that are at least potentially important for the effect of monetary policy on real economic activity include the elimination of Regulation Q interest ceilings and the development of the...

In the financial crisis and recession induced by the Covid-19 pandemic, many investment-grade firms became unable to borrow from securities markets. In response, the Fed not only reopened its commercial paper funding facility but also announced it would purchase newly issued and seasoned bonds...

We propose a novel mechanism, “financial dampening,” whereby loan retrenchment by banks attenuates the effectiveness of monetary policy. The theory unifies an endogenous supply of illiquid local loans and risk-sharing among subsidiaries of bank holding companies (BHCs). We derive an...

We build a variation of the neoclassical growth model in which both wealth shocks (in the sense of wealth destruction) and financial shocks to households generate recessions. The model features three mild departures from the standard model: (1) adjustment costs make it difficult to expand the...

The pronounced and persistent impact of the global financial crisis of 2008 motivates our empirical analysis of the role of institutions and macroeconomic fundamentals on countries' adjustment to shocks. Our empirical analysis shows that the associations of growth level, growth volatility,...

Does the mere presence of big banks affect macroeconomic outcomes? In this paper, we develop a theory of granularity (Gabaix, 2011) for the banking sector, introducing Bertrand competition and heterogeneous banks charging variable markups. Using this framework, we show conditions under which...
