In this paper we extend the proportional rule to division problems with multiple references and we present a result of characterization of the weighted proportional rule. As a particular case, we analyze the problems of probability aggregation and probability updating. division problems with...

This research is designed to help government and tourism policy-makers evaluate the efficiency and consequences of the Greek taxation system on maritime tourism. The tax revenues generated by the taxes and dues imposed by the state are measured using the Tourism Satellite Account (TSA). Tax...

The aim of the paper is to use the data envelopment analysis (DEA) for mining in Zacatecas and provide efficiency indicators in the years 1998, 2003, and 2008. We compare the performance of the state of Zacatecas with other mining states in Mexico. Then the empirical analysis extends to specific...

Global integration of economies over the past two decades has interconnected many of the countries and industries in the world. The World Input Output Database (WIOD) provides domestic output production and use information on 59 industries, in 40 countries that cover 85% of the global output....

Passive investment strategies basically aim to replicate an underlying benchmark. Thereby, the management usually selects a subset of stocks being employed in the optimization procedure. Apart from the optimization procedure, the stock selection approach determines the stock portfolios's...

Even though a random walk process is from a statistical point of view not predictable, some movements can be correlated with specific events concerning other variables. Then, predictable patterns may arise being dependent on this joint event. There is evidence given that equity price busts being...

This paper studies long-term trends of self-employment in Chile. Self-employment is associated with poor job conditions, vulnerability, and instability or informal labor market. Contrary to what is expected, self- employment level does not respond to macroeconomic variables. Using forty-one...

The aim of this paper is to analyze the merits of using the Value At Risk method in estimating the risk associated with investments in metallurgical sector companies. The paper presents how to construct the model, various methods of its estimation and their advantages and disadvantages. In the...

This contribution studies the application of heteroskedasticity robust estimation of Vector-Autoregressive (VAR) models. VAR models have become one of the most applied models for the analysis of multivariate time series. Econometric standard software usually provides parameter estimators that...

I/O models have been widely used to assess the impacts of many changes in an economy. An I/O model is also an important tool to make forecasts and the results from an I/O model are very helpful in many policy-making processes. Many scientific findings in economics have to give credit to the I/O...
