This paper intends to explore the utilization of entropy through politics and election results, an area just slightly explored. It generalizes the interpretation of entropy, considering it a measure of dissatisfaction and disillusion of populations in relation to politics. Some phenomena like...

This paper estimates von Neumann andMorgenstern utility functions comparing the generalized maximum entropy (GME) with OLS, using data obtained by utility elicitation methods. Thus, it provides a comparison of the performance of the two estimators in a real data small sample setup. The results...

This paper utilizes several tests to analyze serial dependence in financial data. In an attempt to provide a better explanation of the behavior of financial markets, we utilized tests that make use of mutual information and developed a detrended fluctuation analysis (DFA). Applying these tests...

Methodologies related with information theory have been increasingly used in studies in economics and management. In this paper we use Generalized Maximum Entropy as an alternative to the Ordinary Least Squares in the estimation of utility functions. We estimated linear, logarithmic and power...

Entropy is a measure of information and uncertainty which has been used recently in different areas, besides of its original utilization in physics. Finance, microeconomics, macroeconomics, utility functions or even psychology are approached areas, using analogies between the areas physics and...

Data envelopment analysis (DEA) is commonly used to measure the relative efficiency of decision-making units. Often, in a second stage, a regression model is estimated to relate DEA efficiency scores to exogenous factors. In this paper, we argue that the traditional linear or tobit approaches to...

The decoupling of CAP payments leads production decisions and resources allocation to be dependent only on market prices and competitive advantages. The objective of this paper is to assess the effects of CAP trends on the montado ecosystem in southern Portugal in terms of land, labour and...

Alqueva dam in the Alentejo Region was developed to solve water scarcity in the South of Portugal and to ensure permanent availability of water for household and industrial consumption, irrigation, production of electric energy, and ecological and environmental purposes. Competition among some...

The arrival of motorization, from before the beginning of the twentieth century, has changed agricultural production and the whole economy by dramatically reducing work force and improving productivity. Yet the negligence of research on the history of farm mechanization is surprising given that...
