Advocates of Medicaid expansion argue that federal Medicaid assistance to states fosters economic activity, generating positive local multiplier effects. Furthermore, during economic downturns, Congress regularly tweaks federal match rates for state Medicaid spending – including during the...

One of the most important channels through which monetary policy affects the real economy is changes in mortgage rates. This paper studies the effects of mortgage rate changes resulting from monetary policy shifts on homeowners’ spending, debt repayment and defaults. The Canadian institutional...

Many empirical studies estimate impulse response functions that depend on the state of the economy. Most of these studies rely on a variant of the local projection (LP) approach to estimate the state-dependent impulse response functions. Despite its widespread application, the asymptotic...

We propose System Projections with Instrumental Variables (SP-IV) to estimate dynamic structural relationships. SP-IV replaces lag sequences of instruments in traditional IV with lead sequences of endogenous variables. SP-IV allows the inclusion of controls to weaken exogeneity requirements, can...

We show that a structural model of firm decisions can produce very flexible implied volatility surfaces: upward and downward sloping, u-shaped. A calibrated version of the model is able to match many unconditional financial characteristics of the average option-able stock, and can help explain...

One of the main channels through which monetary policy stimulus affects the real economy is mortgage borrowing. This channel, however, is weakened by frictions in the mortgage market. The rapid growth of financial technology-based (FinTech) lending tends to ease these frictions, given the higher...

The Cobb-Douglas matching function is ubiquitous in search and matching models, even though it imposes a constant matching elasticity that is unlikely to hold empirically. Using a general constant returns to scale matching function, this paper first derives analytical conditions that determine...

Wealth inequality in the U.S., measured by the top 1% wealth share, experienced dramatic changes in the first year of the COVID-19 pandemic. Economic theory suggests that the key to understanding wealth inequality is heterogeneity in the return to net worth across households. To understand the...

This paper uses confidential data on audit engagement partner names from regulatory filings of bank holding companies (BHC) to investigate whether partners display individual style that affects the financial reporting of the BHCs. We focus on loan loss provisioning. We construct an audit...

This paper is about the nonparametric regression of a choice variable on a nonlinear budget set when there is general heterogeneity, i.e., in the random utility model (RUM). We show that utility maximization makes this a three-dimensional regression with piecewise linear, convex budget sets with...
