This paper employs a Zero Lower Bound (ZLB) consistent shadow-rate model to decompose UK nominal yields into expectation and term premia components. Compared to a standard affine term structure model, it performs relatively better in a ZLB setting and effectively captures the countercyclical...

This study deals with the pricing and hedging of inflation-indexed bonds. Under foreign exchange analogy we model the nominal short rate, real short rate and logarithm of the price index with an affi ne Gaussian process. Using the underlying a ffine property, we compute the nominal and...

This paper applies six recently developed nonparametric tests of serial independence to monthly US stock returns. Findings of previous studies based on the BDS test are sup-ported since most of the new tests also reject the random walk hypothesis. Furthermore, power properties of the new tests...

We introduce a new analytical approach to price American options. Using an explicit and intuitive proxy for the exercise rule, we derive tractable pricing formulas using a short-maturity asymptotic expansion. Depending on model parameters, this method can accurately price options with...

This paper develops a new estimation procedure for characteristic-based factor models of security returns. We treat the factor model as a weighted additive nonparametric regression model, with the factor returns serving as time-varying weights, and a set of univariate non-parametric functions...

This paper investigates the impact of heterogeneous beliefs of professional investors on the currency options market. Using a unique data set with detailed information on the foreign-exchange forecasts of about 50 market participants over more than ten years, we construct an empirical proxy for...

This paper studies the term structure implications of a simple structural economy in which the representative agent displays ambiguity aversion, modeled by Multiple Priors Recursive Utility. Bond excess returns reflect a premium for ambiguity, which is observationally distinct from the risk...

This study finds that a model with internal habit memory allowsto simultaneously explain a series of business cycle and asset pricing puzzles. Compared to the literature, the equity premium puzzle can be resolved in a model with endogenous labor, without giving rise to excessive risk free rate...

What is the fundamental value of a stock? Do stock prices deviate from this fundamental value? If yes, do they go back to their fundamental value? This paper proposes to answer these three questions by using a stock valuation model based on the Consumption-Capital Asset Pricing Model (C-CAPM)...

The large spread between equity returns and risk free rates observed in most stock markets (the "equity premium puzzle") has been subject of intense debates. Two main families of models claim to solve this puzzle: habit formation models and loss aversion models. The goal of this paper is to...
