Richer and healthier agents tend to hold riskier portfolios and spend proportionallyless on health expenditures. Potential explanations include health and wealth eects onpreferences, expected longevity or disposable total wealth. Using HRS data, we perform astructural estimation of a dynamic...

We study the exponential utility indierence value h for a contingentclaim H in an incomplete market driven by two Brownian motions.The claim H depends on a nontradable asset variably correlated withthe traded asset available for hedging. We provide an explicit se-quence that converges to h,...

We consider backward stochastic dierential equations (BSDEs) witha particular quadratic generator and study the behaviour of their solu-tions when the probability measure is changed, the ltration is shrunk,or the underlying probability space is transformed.[...]

We study the exponential utility indifference valuation of a contingentclaim H when asset prices are given by a general semimartingale S. Under mildassumptions on H and S, we prove that a no-arbitrage type condition is fulfilled ifand only if H has a certain representation. In this case, the...

We study utility indifference pricing of claim streams with intertemporalconsumption and power (CRRA) utilities. We derive explicit formulasfor the derivatives of the utility indifference price with respect toclaims and wealth. The simple structure of these formulas is a reflectionof surprising...
