During the Covid-19 crisis, most OECD countries used short-time work (subsidized reductions in working hours) to preserve employment. This paper documents that short-time work affects the behavior of firms (supply) and households (demand). First, using household survey data from Germany, we show...

We argue that capital misallocation arises endogenously due to incomplete consumption insurance. We model risk-averse entrepreneurs with heterogeneous productivity who face idiosyncratic output shocks and choose how much capital to rent before uncertainty unfolds. We show that incomplete markets...

Prepaid electricity contracts lower enforcement costs but may burden consumers, particularly when market frictions are present. This paper presents the results of a randomized control trial where 2,000 randomly selected, rural Rwandese consumers were offered a line of credit for electricity...

We study international monetary policy spillovers and spillbacks in a tractable two-country Heterogeneous Agent New Keynesian model. Relative to Representative Agent (RANK) models, our framework introduces a precautionary-savings channel, as households in both countries face uninsurable income...

This paper analyzes the horizontal spillover effects of Germany's first sectoral minimum wage. Using a difference-in-differences estimation, I examine the impact of the public announcement and introduction of the minimum wage on sub-minimum wage workers in related jobs outside the minimum wage...

This paper explores the link between default risk and fiscal procyclicality. We show that countries with higher sovereign risk have a more procyclical fiscal expenditure policy, which is driven mostly by transfers. We build a small open economy model with income inequality, social transfers, and...

We discover sentiment-driven equilibria in popular models of imperfect risk sharing. In these equilibria, sentiment dynamics behave like uncertainty shocks, in the sense that self-fulfilled beliefs about volatility drive aggregate fluctuations. Because such fluctuations can decouple from the...

Why do fire sales occur if many risks are hedgeable? We study a version of Brunnermeier and Sannikov (2014) in which all fundamental risks can be hedged frictionlessly. Our analysis shows that fire sales are inherently self-fulfilling. Fundamental shocks can never cause fire sales, and an...

Consumer credit spreads significantly impact consumption and asset dynamics, affecting indebted households' spending behavior and the income sensitivity of consumption. Analyzing Danish data, we find that elevated credit spreads reduce consumption of indebted households. Our results suggest that...

We use supervised machine learning to approximate the expectations typically contained in the optimality conditions of an economic model in the spirit of the parameterized expectations algorithm (PEA) with stochastic simulation. When the set of state variables is generated by a stochastic...

Recent empirical studies document that the distribution of earnings changes displays substantial deviations from lognormality: in particular, earnings changes are negatively skewed with extremely high kurtosis (long and thick tails), and these non-Gaussian features vary substantially both over...
