Interest-rate volatility is known to be positively level dependent, i.e., to correlate positively with interest rate levels. However, recent research has provided compelling evidence that as interest rates rise, the amount of level dependence decreases. We advance this line of research by...

Interest-rate benchmark reform has revived short-rate modelling. One reason is that short-rate models provide a consistent framework in which different benchmarks, and contracts linked to them, can be compared. Another reason is that new benchmarks can be directly dependent on very short-term...

Modelling the risk that a financial institution may not be able to roll over short-term borrowing at the market reference rate, we derive the dynamics of (interbank) reference term rates (e.g., LIBOR) and their spread vis-à-vis benchmarks based on overnight reference rates, e.g., rates implied...

I study the relationship between interest rates and interest-rate volatility, particularly the idea of unspanned stochastic volatility (USV): volatility risk that cannot be hedged with bonds or swaps. Simulated data is used to assess the ability of regression-based techniques, popular but...

We develop a structural model of the firm that allows after-interest cash to be directed to dividends, buybacks or some combination thereof. We study the effects of dilutions and buybacks on the value of the firm's claimants and on options written on the stock. We distinguish between options on...
