A monetary authority can be committed to pursuing an inflation, price-level, or nominal output target yet systematically fail to achieve the specified goals. Constrained by the zero lower bound on the policy rate, the monetary authority is unable to implement its objectives when private-sector...

I construct the life-cycle model with equilibrium default and preferences featuring temptation and self-control. The model provides quantitatively similar answers to positive questions such as the causes of the observed rise in debt and bankruptcies and macroeconomic implications of the 2005...

REVISED MARCH 2019 Using a representative-household search and matching model with endogenous labor force participation, we study the interactions between extensive-margin labor supply elasticities and the cyclicality of labor force participation flows. Our model successfully replicates salient...

Supersedes Working Paper 17-17. Fintech has been playing an increasing role in shaping financial and banking landscapes. There have been concerns about the use of alternative data sources by fintech lenders and the impact on financial inclusion. We compare loans made by a large fintech lender...

Supercedes 15-03 We employ a unique data set to examine the spatial clustering of private R&D labs. Instead of using fixed spatial boundaries, we develop a new procedure for identifying the location and size of specific R&D clusters. Thus, we are better able to identify the spatial locations of...

Superceded by 16-25. This working paper supersedes WP 12-22, WP 11-42, and WP 10-33. We employ a unique data set to examine the spatial clustering of private R&D labs, and, using patent citations data, we provide evidence of localized knowledge spillovers within these clusters. Jaffe,...

The purpose of this paper is to identify possible sources of the secular decline in the job separation rate over the past four decades. I use a simple labor matching model with two types of workers, experienced and inexperienced, where the former type faces a risk of skill loss during...

We employ a unique data set to examine the spatial clustering of private R&D labs, and, using patent citations data, we provide evidence of localized knowledge spillovers within these clusters. Jaffe, Trajtenberg, and Henderson (1993, hereafter JTH) provide an aggregate measure of the importance...

This paper examines how instances of identity theft that are sufficiently severe to induce consumers to place an extended fraud alert in their credit reports affect their risk scores, delinquencies, and other credit bureau variables on impact and thereafter. We show that for many consumers these...

REVISED MARCH 2019 This paper studies the effects of Los Angeles Metro Rail on the spatial distribution of people and prices. Using a panel of bilateral commuting flows, I estimate a quantitative spatial general equilibrium model to quantify the welfare benefits of urban rail transit and...
