We propose an easy-to-use search friction in the goods markets in medium-sized New Keynesian models. This friction allows increases in measured productivity in response to increases in expenditures via higher search effort from households. As a result markups can become procyclical and labor...

We provide a macroeconomic theory where demand for goods has a productive role. A search friction prevents perfect matching between producers and potential customers. Larger demand induces more search, which in turn increases GDP and measured TFP. We embed the product-market friction in a...

We estimate labour supply elasticities at the micro level and show what we can learn from possibly very heterogeneous elasticities for aggregate behaviour. We consider both intertemporal and intratemporal choices, and identify intensive and extensive responses in a consistent life-cycle...

In the data sovereign default is always partial and varies in its duration. Debt levels during default episodes initially increase and do not experience reductions upon resolution. This paper presents a theory of sovereign default that replicates these properties, which are absent in standard...

This paper proposes a new equilibrium concept - organizational equilibrium - for models with state variables that have a time-inconsistency problem. The key elements of this equilibrium concept are: (1) agents are allowed to ignore the history and restart the equilibrium; (2) agents can wait for...

What is the role of credit scores in credit markets? We argue that it is a stand in for a market assessment of a person's unobservable type (which here we take to be patience). We pose a model of persistent hidden types where observable actions shape the public assessment of a person's type via...

To slow COVID-19, many countries have shut down part of the economy. Older individuals have the most to gain from slowing virus diffusion. Younger workers in sectors that are shuttered have most to lose. In this paper, we build a model in which economic activity and disease progression are...

In this paper, we employ both calibration and modern (Bayesian) estimation methods to assess the role of neutral and investment-specific technology shocks in generating fluctuations in hours. Using a neoclassical stochastic growth model, we show how answers are shaped by the identification...

In this paper we construct a stochastic overlapping-generations general equilibrium model in which households are subject to aggregate shocks that affect both wages and asset prices. We use a calibrated version of the model to quantify how the welfare costs of severe recessions are distributed...

We ask two questions related to how access to credit affects the nature of business cycles. First, does the standard theory of unsecured credit account for the high volatility and procyclicality of credit and the high volatility and countercyclicality of bankruptcy filings found in U.S. data?...
