We prove that the English auction (with bidders that need not be ex ante identical and may have interdependent valuations) has an efficient ex post equilibrium. We establish this result for environments where it has not been previously obtained. We also prove two versions of the...

After the criterion of time to examine the evolution of the indicator values that can be given at the time (eg number of human population in year t) or the time (eg GDP in year t). The indicators characterizing economic development are absolute growth, growth rate, the rate increase.

Economic information, such as interpersonal relationships, and lead are usually placed at the basis of the facts and circumstances must always be based on a economic theory well argued. Relations between employees and managers should provide related information in terms of social issues,...

The economic, social, demographic, technological achievements, uneven distribution of raw materials, energy resources, require the opening of all economic systems. Mathematical models, came to help the arguments in this case, I propose a way to "experience" what the real situation is impossible....

Abstract: The partial information rational expectations solution to a general linear multivariate expectational macro-model is found when agents are uncertain about the true values of the model’s parameters. Necessary and sufficient conditions for convergence to the full information rational...

In this paper, we obtain bounds for the population coefficient of variation (CV) in Bernoulli, Discrete Uniform, Normal and Exponential distributions. We also show that the sample coefficient of variation (cv) is not an accurate estimator of the population CV in the above indicated...

The aim of the article is to introduce a mathematical concept of indecisiveness into the analytic hierarchy process (AHP) framework. Indecisiveness can be useful in two ways: first, decision makers with high indecisiveness (higher than a given threshold value) can be excluded from a decision...

One of the most pressing problems in the Latvian economy is related to the energy sector. The most characteristic feature is coupled with the low efficiency of thermal energy consumption of households as a result of poor insulation of existing buildings in Latvia. Solving energy sector problems...

The measurement of economies no longer by GDP alone, but by an Index that includes other important factors as well, a Social factors relativized GDP. Social factors relativized GDP: GDP – GDP x GINI = K_Index Written differently: (1 – GINI) x GDP = K_Index Inflation indexed Version: (1 –...

By using conditional directional distance functions this paper investigates the effect of regional economic growth on regions’ environmental efficiency in greenhouse gas emissions. A sample of ninety eight regions (NUTS 2 level) from Germany, France and the U.K. has been used and regional...
