Increases in firm default risk raise the default probability of banks while decreasing output and inflation in US data. To rationalize the empirical evidence, we analyse firm risk shocks in a New Keynesian model where entrepreneurs and banks engage in a loan contract and both are subject to...

We characterize optimal monetary policy in a New Keynesian search-and-matching model where multiple-worker firms satisfy demand in the short run by adjusting hours per worker. Imperfect product market competition and search frictions reduce steady state hours per worker below the efficient...

We study the equilibrium properties of a business cycle model with financial frictions and price adjustment costs. Capital-constrained entrepreneurs finance risky projects by borrowing from banks. Banks, in turn, make loans using equity and deposits. Because financial contracts are not...

The European Central Bank's asset purchase programs, while intended to stabilize the economy, may have unintended side effects on financial stability. This paper aims at gauging the effects on financial markets, the banking sector, and lending to non-financial firms. Using a structural vector...

The Euro Area is characterized by little variation in unemployment and strongly procyclical labor productivity. We capture both characteristics in a New Keynesian business cycle model with labor search frictions, where labor can vary along three margins: employment, hours, and effort. We...

We introduce two types of effort into an otherwise standard labor search model to examine indeterminacy and sunspot equilibria. Variable labor effort gives rise to increasing returns to hours in production. This makes workers more valuable and contributes to self-fulfilling profit expectations,...

Price setting has become more flexible following a string of large adverse shocks (Covid-19, the Ukraine War). We argue that a shift to a high-uncertainty regime incentivizes firms to invest in their ability to adjust prices. We formalize this idea in a general equilibrium model with endogenous...

We identify the effects of corporate income tax shocks on key US macroeconomic aggregates. In response to a corporate income tax cut, we find that: (i) labor productivity increases; (ii) entry increases with delay; (iii) exit increases; (iv) total labor increases by more than production labor....

Geopolitical risk cannot be measured in a universal way. We develop new geopolitical risk indicators relying on local newspaper coverage to account for different perceptions. Using Russia as a case study, we demonstrate that geopolitical risk shocks identified from local news sources have...

As part of Germany’s fiscal response to the Covid-19 pandemic, parents received three payments totalling e450 per child. Randomization in the payment dates and daily scanner data allow us to identify the effects of these transfers on household spending. We find a significant but small spending...
