We identify a wealth redistribution channel which creates a monetary policy trade-off whereby short-term economic stimulus is followed by persistently lower output over the medium term. This trade-off is stronger in economies with more nominal household debt but weakened by a more aggressive monetary policy stance and under price-level targeting. Given this channel, negative supply shocks become more severe and persistent. The interaction of heterogeneous labor supply with heterogeneous net nominal asset positions of households is crucial for the medium-term implications of this channel, which we show analytically and in the context of an estimated New Keynesian general equilibrium model with household heterogeneity.

We study third-party loan guarantees in a model in which lenders can screen and sell loans before maturity when in need of liquidity. Loan guarantees improve market liquidity, reduce lending standards, and can have a positive overall welfare effect. Guarantees improve the average quality of \textit{non-guaranteed} loans traded and thus the market liquidity of these loans due to selection. This positive pecuniary externality provides a rationale for guarantee subsidies. Our results contribute to a debate about reforming government-sponsored mortgage guarantees by Fannie Mae and Freddie Mac, suggesting that the excessively high subsidies to these guarantees should be reduced but not completely eliminated.

This paper studies the efficiency of financial intermediation through securitization in a model with heterogeneous lending opportunities and asymmetric information about the quality of securities. Issuers of securities can signal their quality by providing recourse to security buyers. I find that signaling increases the variation in the degree of asymmetric information over the business cycle, which creates the documented growth asymmetry in the cycle. In particular, in the boom stage of the business cycle, security quality remains private information and lower-quality securities accumulate on the balance sheets of lenders. This inefficient allocation of capital implies a deeper drop in output in a subsequent recession proportional to the length of the preceding boom.

The neutral rate of interest is an important concept and communication tool for central banks. We develop a small open economy model with overlapping generations to study the determinants of the neutral real rate of interest in a small open economy. The model captures domestic factors such as population aging, declining productivity, rising government debt and inequality. Foreign factors are captured by changes in the global neutral real rate. We use the model to evaluate secular dynamics of the neutral rate in Canada from 1980 to 2018. We find that changes in both foreign and domestic factors resulted in a protracted decline in the neutral rate.

Markets for securitized assets were characterized by high liquidity prior to the recent financial crisis and by a sudden market dry-up at the onset of the crisis. A general equilibrium model with heterogeneous investment opportunities and information frictions predicts that, in boom periods or mild recessions, the degree of adverse selection in resale markets for securitized assets is limited because of the reputation-based guarantees by asset originators. This supports investment and output. However, in a deep recession, characterized by high dispersion of asset qualities, there is a sudden surge in adverse selection due to an economy-wide default on reputation-based guarantees, which persistently depresses the output in the economy. Government policy of asset purchases limits the negative effects of adverse selection on the real economy, but may create a negative moral hazard problem.

Bail-in bonds have gained a lot of attention among bank regulators. These bonds supposedly raise the hurdle for a government bailout by converting into loss-absorbing capital once the issuing bank runs into trouble. We argue that banks can short-circuit bail-in requirements by offering investors off-balance-sheet insurance against conversion. The bond itself appears as a bail-in bond on the issuer's balance sheet while the insurance is booked off balance sheet until the bond converts. The government can deter insurance provision by imposing penalties when insurance is discovered, but these penalties may not be credible. We find conditions for an equilibrium in which insurance against conversion is provided by banks and bailed out by the government rather than penalized upon discovery. We also present new empirical evidence in support of our model.
