This paper studies nonlinear cointegration models in which the structural coefficients may evolve smoothly over time. These time-varying coefficient functions are well-suited to many practical applications and can be estimated conveniently by nonparametric kernel methods. It is shown that the...

The rational expectation hypothesis is widely used in finance and macroeconomics. A natural research question comprises investigating whether models that use this hypothesis can fit the data well. Researchers have been developing econometric procedures to test rational expectation models....

We propose a monitoring procedure to detect a structural change from stationary to integrated behavior. When the procedure is applied to the errors of a relationship between integrated series it thus monitors a structural change from a cointegrating relationship to a spurious regression. The...

We contribute to the finance literature in two main ways. First, we present a theoretical capital asset pricing model (CAPM) to price assets in different market structures. Second, we use our model to analyze whether when markets are partially segmented using the local or the global CAPM yields...

The paper focused on measuring efficiency of investment strategies and portfolio optimization based on dynamic portfolio formation using the global minimum variance approach in a region of central European countries. The paper analyses DCC GARCH model, which was employed in order to obtain...

The paper develops a simple model to explain Covered Interest Parity (CIP) deviations. The model allows for a time-varying country risk premium and is used to motivate a Structural Vector Auto-Regression (SVAR) approach to study the joint dynamics of the Covered Interest Differential (CID) and...

This article proposes a theoretical testable ICAPM for partially segmented markets. We establish that if some investors do not hold all international assets because of implicit and/or explicit segmentation factors, the world market portfolio is not efficient and the classic ICAPM must be...
