We develop a dynamic general equilibrium model to analyze the effects of central bank purchases of government bonds by investigating the following three questions: Under what conditions are these purchases socially desirable, what incentive problems do they mitigate, and how large are these...

We develop a microfounded model, where agents have the possibility to trade money for government bonds in an over-the-counter market. It allows us to address important open questions about the effects of central bank purchases of government bonds, these being: under what conditions these...

A consistent empirical feature of bond yields is that term premia are, on average, positive. That is, investors in long term bonds receive higher returns than investors in similar (i.e.\ same default risk) shorter maturity bonds over the same holding period. The majority of theoretical...

In the post-crisis period, increased regulation of financial intermediaries led to a significant decline in corporate bond market liquidity. In order to stabilize these markets, policy makers recently proposed that the trading of corporate bonds should be more centralized. In this paper, we show...

We show that trade frictions in OTC markets result in inefficient private liquidity provision. We develop a dynamic model of market-based financial intermediation with a two-way interaction between primary credit markets and secondary OTC markets. Private allocations are generically inefficient...

The first chapter, which is joint work with Anders B. Trolle, analyzes whether liquidity risk is priced in the cross section of returns on credit default swaps (CDSs). The analysis is based on a factor pricing model and a tradable liquidity factor that is constructed from returns on index...

The third chapter documents a decline of transaction costs and profits from liquidity provision in the index CDS market over a two-and-a-half-year period during which Dodd-Frank regulations were implemented. Transaction costs and profits from liquidity provision declined around the introduction...
