We argue that the US personal saving rate's long stability (1960s-1980s), subsequent steady decline (1980s-2007), and recent substantial rise (2008-2011) can be interpreted using a parsimonious buffer stock model of consumption in the presence of labor income uncertainty and credit constraints....

This paper develops a simple New Keynesian model incorporating a small time-varying probability that the economy is struck by a disaster in the future. The model's main prediction is that a small increase in the disaster probability causes a recession in the economy, speci cally due to limited...

This paper analyzes the welfare costs of business cycles when workers face uninsurable idiosyncratic labor income risk. In accordance with the previous literature, this paper decomposes labor income risk into an aggregate and an idiosyncratic component, but in contrast to the previous...

In this paper our main aim is to quantify the role that housing collateral plays for the monetary transmission mechanism. Furthermore, we want to explore the implications of the increase in household indebtedness, and specifically the loan-to-value ratio, in the last two decades. We set up a two...

This paper studies how tax-and-transfer progressivity influences aggregate fluctuations when interacting with household heterogeneity. Using a simple static model of the extensive margin labor supply, we analytically characterize how a degree of progressivity influences differential labor supply...

This paper employs a calibrated model of the US economy to analyze the boom and bust in house prices as well as the shifts in the distribution of wealth during the years around the Great Recession. We replicate the dynamics of the housing market using shocks to aggregate income, the distribution...

In this paper, we assess how risk-sharing channels have evolved over time in the United States and the Euro Area, and whether they have operated as "complements" or "substitutes". In particular, we focus on the capital channel (income from cross-border ownership of productive assets), the credit...

I study debt relief as a stimulus policy using a dynamic stochastic general equilibrium model that captures the rich heterogeneity in households' balance sheets. In this environment, a large-scale mortgage principal reduction can amplify a recovery, support house prices and lower foreclosures....

I study how unsecured credit affects the extent to which unemployment insurance (UI) policies smooth cyclical fluctuations in aggregate consumption. To do so, I develop a real business cycle model with incomplete asset markets, frictional labor markets, and defaultable debt. Using empirically...

This paper provides an extensive analysis of card spending during the COVID-19 pandemic in Turkey by using weekly aggregated and sectoral credit and debit card spending data from March 2014 to December 2020. At an aggregated level, we show that aggregate demand decreases significantly at the...
