A good description of the dynamics of interest rates is crucial to price derivatives and to hedge corresponding risk. Interest rate modelling in an unstable macroeconomic context motivates one factor models with time varying parameters. In this paper, the local parameter approach is introduced...

Let (X1, Y1), ..., (Xn, Yn) be i.i.d. rvs and let v(x) be the unknown T-expectile regression curve of Y conditional on X. An expectile-smoother vn(x) is a localized, nonlinear estimator of v(x). The strong uniform consistency rate is established under general conditions. In many applications it...

A recent book by Kolari, Liu, and Huang (KLH) (2021) developed a new theoretical capital asset pricing model dubbed the ZCAPM, which outperformed well-known multifactor models in cross-sectional tests using U.S. stocks. This paper extends their analyses by employing a longer sample period from...

Kolari, Liu, and Huang (2021) recently proposed and empirically tested a new asset pricing model dubbed the ZCAPM that consistently outperformed popular multifactor models using U.S. stock returns. Is the ZCAPM a false discovery? As verification, this paper provides international stock return...
