We analyze a general-equilibrium asset pricing model where a small subset of the consumers/investors have a short-run ldquo;urge to saverdquo;. That is, their attitude toward consumption in the long run is a standard one they do place zero weight on consumption far enough out in the future but...

We investigate markets for defaultable sovereign debt in which even though there are many identical lenders and symmetric information (including no hidden actions), perfect competition does not obtain. When a private lender allows a sovereign country to increase its level of indebtedness, that...

Extreme market outcomes are often followed by a lack of liquidity and a lack of trade. This market collapse seems particularly acute for markets where traders rely heavily on a specific empirical model such as in derivative markets. Asset pricing and trading, in these cases, are intrinsically...

We provide an axiomatic model of preferences over atemporal risks that generalizes Gul (1991) A Theory of Disappointment Aversion' by allowing risk aversion to be first order' at locations in the state space that do not correspond to certainty. Since the lotteries being valued by an agent in an...

We explore the practitioners methodology of choosing time-dependent parameters to fit a bond model to selected asset prices, and show that it can lead to systematic mispricing of some assets. The Black-Derman-Toy model, for example, is likely to overprice call options on long bonds when interest...

Mathematical models of bond pricing are used by both academics and Wall Street practitioners, with practitioners introducing time-dependent parameters to fit acirc;not;Sarbitrage-freeacirc;not;? models to select asset prices. We show, in a simple one-factor setting, that the ability of such models...

We provide a useracirc;not;quot;s guide to acirc;not;Sexoticacirc;not;? preferences: nonlinear time aggregators, departures from expected utility, preferences over time with known and unknown probabilities, risk sensitive and robust control, acirc;not;Shyperbolicacirc;not;? discounting, and...

Prices of riskfree bonds in any arbitrage-free environment are governed by a pricing kernel: given a kernel, we can compute prices of bonds of any maturity we like. We use observed prices of multi-period bonds to estimate, in a log- linear theoretical setting, the pricing kernel that gave rise...
