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...

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 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 integrate an overlapping generations model into a new monetarist framework and show that the Friedman rule is not optimal. This is because inflation makes saving for retirement less attractive, such that young agents optimally choose to increase their consumption at the expense of lower...

We develop a dynamic general equilibrium model to analyze the relationship between monetary policy, money demand, and unemployment. Our model succeeds in replicating the empirical fact of a downward sloping Phillips curve for low inflation rates and an upward sloping curve for high inflation...

Shortages in organs for transplantation have resulted in a renewed interest in designing incentive policies to promote organ supply. The donor-priority rule, which grants priority for transplantation based on deceased organ donor registration status, has proven to be effective in both theory and...

Do financial market participants free-ride on liquidity? To address this question, we construct a dynamic general equilibrium model where agents face idiosyncratic preference and technology shocks. A secondary financial market allows agents to adjust their portfolio of liquid and illiquid assets...

Can there be too much trading in financial markets? To address this question, we construct a dynamic general equilibrium model, where agents face idiosyncratic preference and technology shocks. A financial market allows agents to adjust their portfolio of liquid and illiquid assets in response...

In the 1990s, the empirical relation between money demand and interest rates began to fall apart. We analyze to what extent improved access to money markets can explain this break-down. For this purpose, we construct a microfounded monetary model with a money market, which provides insurance...

We investigate the positive and normative implications of a tax on financial market transactions in a dynamic general equilibrium model, where agents face idiosyncratic liquidity shocks and financial trading is essential. Our main finding is that agents' portfolio choices display a pecuniary...
