Alterntive tests for monotonicity in expected asset returns
Romano, Joseph P.; Wolf, Michael - 2011
Many postulated relations in finance imply that expected asset returns should monotonically increase in a certain characteristic. To examine the validity of such a claim, one typically considers a finite number of return categories, ordered according to the underlying characteristic. A standard...

Nonparametric Regression on Latent Covariates with an Application to Semiparametric GARCH-in-Mean Models
Conrad, Christian; Mammen, Enno - 2008
We consider time series models in which the conditional mean of the response variable given the past depends on latent covariates. We assume that the covariates can be estimated consistently and use an iterative nonparametric kernel smoothing procedure for estimating the conditional mean...

Some Recent Developments in Predictive Accuracy Testing With Nested Models and (Generic) Nonlinear Alternatives
Corradi, Valentina; Swanson, Norman R. - 2003
Forecasters and applied econometricians are often interested in comparing the predictive accuracy of nested competing models. A leading example of nestedness is when predictive ability is equated with ?out-of-sample Granger causality?. In particular, it is often of interest to assess whether...

The determinants of stock and bond return comovements
Baele, Lieven; Bekaert, Geert; Inghelbrecht, Koen - 2007
We study the economic sources of stock-bond return comovement and its time variation using a dynamic factor model. We identify the economic factors employing structural and non-structural vector autoregressive models for economic state variables such as interest rates, (expected) inflation,...

Option-implied term structures
Vogt, Erik - 2014
The illiquidity of long-maturity options has made it difficult to study the term structures of option spanning portfolios. This paper proposes a new estimation and inference framework for these option-implied term structures that addresses long-maturity illiquidity. By building a sieve estimator...
