Most extant structural credit risk models underestimate credit spreads while matching default rates, recoveries, leverage, and equity risk premia - a shortcoming known as the credit spread puzzle. We calibrate and estimate a model able to explain medium to long-term credit spreads by...

We embed systematic default, pro-cyclical recovery rates and habit persistence into a model with a slight possibility of a macroeconomic disaster of reasonable magnitude. We derive analytical solutions for defaultable bond prices and show that a single set of structural parameters calibrated to...

This paper proposes a preference-based general equilibrium model that explains the pricing of the S&P 500 index options since the 1987 market crash. The central ingredients are a peso component in the consumption growth rate and the time-varying risk aversion induced by habit formation that...

This paper examines the joint time series of the S&P500 index and its options with a two-factor Hawkes jump-diffusion model that captures jump propagation (i.e., the phenomenon in which the strike of one jump substantially raises the probability for more to follow). The propagation effect...

We embed systematic default, procyclic recovery rates and habit persistance into a model with a slight possibility of a macroeconomic disaster of reasonable magnitude. We derive analytical solutions for defaultable bond prices and show that a single set of structural parameters calibrated to the...

This paper examines the effects of major event risk on the optimal intertemporal asset allocation in a continuous time setting. We start by firstly proposing a general framework in which we model three types of event risks: i) the individual jumps of asset prices, ii) the individual jumps of the...

This paper outlines a dynamic model with three levels of government: federal, state and local in the Stackelberg game structure with the superor government as the leader and all its subordinate governments the followers.It studies the optimal design of block grants and matching grants from both...

This paper studies the impacts of the interactions between the changing macroeconomic conditions and the nature of competition on firms' investment timing decisions. With a model featuring business-cycle variations in both the profit level and the expected growth rate and volatility of the...

We show that the slight possibility of a macroeconomic disaster of moderate magnitude can explain important features across credit, option, and equity markets. Our consumption-based equilibrium model captures the empirical level and volatility of credit spreads, generates a flexible credit term...
