The identification of environmentally stressed areas for planning soil conservation measures requires an efficient decision support tool to provide appropriate weights for various topographical, morphological, climatological and management factors responsible for soil erosion. In the present...

Groundwater being an important component of the hydrological cycle, estimation of its annual replenishment is essential to evolve a plan for optimum utilization. Groundwater balance approach, which is used extensively for the quantification of recharge and discharge components has been adopted...

The development of rainfall runoff relationship for ungauged watersheds using topography, geomorphology and other regional information remains the most active area of research in the field of hydrology. In the developing countries, some thumb rules and very old equations are in practice for...

A decision-theoretic framework is described for sequential classification when the parameter space is a finite partially ordered set. An example of an optimal strategy is then presented. This example establishes that an asymptotically optimal class of experiment selection rules is not...

This paper discusses the state of economic policy advice in Germany and describes and analyses the results of a new ranking of German economists which not only measures individual economists’ impact on research (via the h-index), but also their impact on the general public (through media...

In an uncertain world, decisions by market participants are based on expectations. Thus, sentiment indicators reflecting expectations are proven at predicting economic variables. However, survey respondents largely perceive the world through media reports. Typically, crude media information,...

In economic literature comparisons between the American and German Council of Economic Advisors lead to the result that the American Council works quite well, whereas the German Council is broadly criticized. On a closer look, these conclusions are disputable. Therefore, in this contribution we...

This contribution provides a game theoretical derivation of market demand for status goods as a function of the level and distribution of income: if (1) the price is sufficiently low, everyone buys the good; if (2) the price is sufficiently high, only the rich buy the good (a status good in a...

The (socio-)psychological concepts of individual aspiration for con- formity and consistency are integrated into the rational-choice frame- work. By using this integrative approach it is shown that after a shock the aspiration for conformity results in an equilibrium which deviates from the homo...
