We analyse the effects of central bank government bond purchases in an estimated DSGE model for the euro area. In the model, central bank asset purchases are relevant in so far as agency costs distort banks' asset allocation between loans and bonds, and households face transaction costs when...

This article studies long-horizon dynamic asset allocation strategies with recursive parameter updating. The parameter estimates for the regime-switching dynamics vary as more and more datapoints are observed and the sample size increases. In such a setting, the globally optimal portfolio...

We consider the optimal stopping of a class of spectrally negative jump diffusions. We state a set of conditions under which the value is shown to have a representation in terms of an ordinary nonlinear programming problem. We establish a connection between the considered problem and a stopping...

Recent empirical studies suggest a downward sloping term structure of Sharpe ratios. We present a theoretical framework in continuous time that can cope with such a non-flat forward curve of risk prices. The approach departs from an arbitrage-free and incomplete market setting when different...

Investments in energy technologies are substantially governed by climate policy. We demonstrate analytically that price-based instruments, such as carbon-taxes, and quantity-based regulations, like emission trading systems, have distinct effects on the (co-)variance of power plant profits. If...

Using a unique data set on German banks' sector specific loan exposures to the real economy and the corresponding write-offs and write-downs, we examine the impact of loan portfolio sector concentration on credit risk. By controlling for common risk factors, we separate the bank-specific...

Mutual funds' exposure to corporate bonds has brought concerns about risks arising from liquidity transformation back to the fore. With a focus on fund asset liquidity and investors, this paper explores the flow-performance relationship and the liquidity management of funds in the presence of...

We investigate how personal income taxes affect the portfolio share of personal wealth that entrepreneurs invest in their own business. In a reformulation of the standard portfolio choice model that allows for underreporting of private business income to tax authorities, we show that a fall in...

We theoretically show that there is a fundamental disconnect be- tween the disposition effect, i.e., investors’ tendency to sell winning assets too early and losing assets too late, and its common empirical measure, namely a positive difference between the proportion of gains and losses re-...

We develop a portfolio balance model to analyze the impact of euro area quantitative easing (QE) on asset yields. Our model features two countries each populated by two agents representing their respective banking and mututal fund sectors. Agents, which differ in their preferences for assets,...
