The purpose of this article is to provide a survey of the presence of speculative bubbles. The empirical study uses a new technique borrowed from statistical physics suggested by Pincus (1991). We use approximate entropy to test the presence of bubbles in the Tunisian and French markets. To this...

It is not easy to determine whether water is really scarce in the physical sense or whether it is available, but people cannot get access to it, or use it better. This paper reviews selected physical water scarcity indicators, and criticisms made against them on several grounds. Under the...

In this paper an alternative approach for the estimation of higher-order linear fixed-effects models is described. The strategy relies on the transformation of the data prior to calculating estimations of the model. While the approach is computationally intensive, the hardware requirements for...
