Using the Malmquist productivity index and panel data methods, we study the role of total human capital and its composition in the technological “catch-up” process and productivity growth via the channels of innovation and adoption of technology in a panel of 19 sub -Saharan African...

Extant empirical research has reported nonlinear behavior within arbitrage relationships. In this article, the authors consider potential nonlinear dynamics within FTSE‐100 index and index‐futures. Such nonlinearity can be rationalized by the existence of transactions costs or through the...

This paper tests for the presence of output mean and variance nonlinearities in international industrial production and UK and US sectoral production growth rates using ARMA-GQARCH, bilinear (BL) and joint BL-GQARCH models. ARMA-GQARCH models confirm the presence of asymmetric variance effects...

Recent research investigating the properties of high‐frequency financial data has suggested that the stochastic nonlinearity widely present in such data may be characterized by heterogeneous components in conditional volatility, and nonlinear dependence of threshold autoregressive form due to...
