Movements in asset prices are a major risk confronting individuals. This paper establishes new asset pricing results when agents differ in risk preference, time preference and/or expectations. It shows that risk tolerance is a critical concept driving savings decisions, consumption allocations,...

We completely characterize the fundamental relationship between the exchange rate and the asset pricing in the two denomination currencies involved when markets are incomplete. Assuming arbitrage-free, perfectly integrated, frictionless but potentially incomplete financial markets, the exchange...

We use principal component analysis on 55 bilateral exchange rates of 11 developed currencies to identify two important global risk sources in FX markets. The risk sources are related to Carry and Dollar but are not spanned by these factors. We estimate the market prices associated with the two...

By assuming that stochastic discount factor (SDF) M be a proper but unspecified function of state variables X, we show that this function M(X) must solve a simple second-order linear differential equation specified by state variables' risk-neutral dynamics. Therefore, this assumption determines...

We analyze whether the timing of public information releases affects risk-sharing and pricing in a pure exchange economy. Information releases do not matter if agents have time additive preferences, homogeneous beliefs and access to complete markets. In the case of heterogeneity in agents'...

We construct mean-variance optimized currency portfolios and analyze the time- series variation of the conditional Sharpe ratio. Returns, volatility and skewness are predictable. Market timing – i.e., trading more (less) aggressively when the conditional risk-return trade-off is more (less)...
