If we intend to support sustainability in the financial markets, research and analysis must come first. In the last 30 years, the groundwork has been laid by the Ethical Environmental Research Group (Forschungsgruppe Ethisch-Ökologisches Rating) leading to a rating system for Impact Investing....

This paper investigates the problem of testing for the symmetry of linear time series driven by asymmetric innovations. In particular, we examine the performance of alternative symmetry tests when innovations are fat tailed. Among the tests considered, only the test based on the tail estimator...

This article suggests an efficient self-directed learning method that will help improve students' actual English ability by adopting Facebook, which is one of the most represented social networking services (SNS). The purpose of this article is to present a practical way in which to implement...

Summary Nonlinear dynamics in the term structure of German interest rates resulting from heterogenous transaction costs in the money market are analysed by means of the smooth transition technique introduced by Granger and Teräsvirta (1993). Tests for linearity, specific functional forms and...
