This paper analyzes empirical market utility functions and pricing kernels derived from the DAX and DAX option data for three market regimes. A consistent parametric framework of stochastic volatility is used. All empirical market utility functions show a region of risk proclivity that is...

The growing number of electric vehicles (EVs) will challenge the power system, but EVs may also have balancing effects via smart charging. Modeling EVs’ system-level impact while respecting computational constraints requires the aggregation of individual profiles. We show that studies...

This paper studies equilibrium in a pure exchange economy with unobservable Markov switching consumption growth regimes and regime-dependent preferences. Variations in risk attitudes have fundamental effects on the structure of equilibrium. Explicit solutions are provided for the market price of...

I study time-variation in variance discount rates, defined as the expected returns for investing in variance risk. I show that variance discount rates drive a significant fraction of the variation in prices of S&P 500 variance swaps. This analysis offers important insights into preferences of...
