We study the labour market and welfare effects of expanding unemployment insurance benefits and introducing payroll subsidies during the COVID-19 pandemic. We find that both policies are complementary and are beneficial to different types of workers. Payroll subsidies preserve the employment of workers in highly productive jobs, while unemployment insurance replaces lost income for workers who experience inevitable job loss.

Many studies in macroeconomics argue that financial frictions do not amplify the impacts of real shocks. This finding is based on models without endogenous default on loans and bank capital. Using a model featuring endogenous interactions between firm default and bank capital, this paper revisits the propagation mechanisms of real and financial shocks.

This paper builds a two-country DSGE model to study the quantitative impact of financial frictions on business cycle co-movements when investors have foreign asset exposure. The investor in each country holds capital in both countries and faces a leverage constraint on her debt.

We develop an equilibrium model of the monetary policy transmission mechanism that highlights information frictions in the market for money and search frictions in the market for labour.

This paper studies exchange rate dynamics by incorporating bounded rationality, that is, limited foresight, in a small open-economy model. This behavior of limited foresight helps explain several observations and puzzles in the data of exchange rate movements.

What is the optimal tax schedule in over-the-counter markets, e.g., those for corporate bonds? I find that an optimal tax schedule is often non-monotonic. For example, trading of some high-price assets should be subsidized, and trading of some low-price assets should be taxed.

Consider the monetary model of Lagos and Wright (JPE 2005) but with general preferences and general production. I show that preferences satisfying UXXUHH – (UXH)2 = 0 is a sufficient condition for the existence and uniqueness of monetary equilibrium with degenerate money distribution.

We present a model of central bank collateralized lending to study the optimal choice of the haircut policy. We show that a lending facility provides a bundle of two types of insurance: insurance against liquidity risk as well as insurance against downside risk of the collateral.

The authors provide some of the first empirical evidence on labour market adjustments to exchange rate movements in Canadian manufacturing industries.

This paper examines the effects of time-varying volatility on welfare. I construct a tractable endogenous growth model with recursive preferences, stochastic volatility, and capital adjustment costs.
