The deep economic modifications suffered by the State of Ceará, in the last two decades, have been increasing the consumption of production factors, among them, water and energy, essential to most productive activities. However, as the supply of both inputs, in the region, is limited, a...

There is a growing recognition in the economic development literature that one of the major impediments to growth and development in the next will be access to water. In recognition of this emerging problem, the present research aims to provide a formal link between water consumption and...

This study focuses on the measure of inter-regional trade of virtual water, defined as the freshwater consumed for producing traded goods and services, to explain the relationship between China’s regional virtual water and the increasing water demand. By using the multi-regional input-output...

The consideration of both the direct and the indirect effects of global production and trade is the first step in order to assess the sustainability of resource exploitation, in particular water usage. This paper applies the Global Multi-Regional Input-Output model to quantify the...

This study estimates the economic cost of mining pollution on water resources for the years 2008 and 2009 based on the conceptual framework of Environmental Efficiency (Pittman, 1981.1983, Färe et al., 1989, 1993, 2003; Rao, 2000). This framework understands such costs as the mining companies...

The paper assesses the sustainability of investment in various economic sectors, with the aim of minimizing resource use and generation of emissions. The broad development focus of the paper and the potential for the proposed methodology to be applied in many different countries make it a useful...

En este estudio se aproximan los costos económicos de la contaminación ambiental minera sobre los recursos hídricos para 2008 y 2009 en el marco conceptual de la Eficiencia Medioambiental, que interpreta dichos costos como el trade-off de los empresarios mineros entre incrementar su...

We present a method of calculating the maximal eigenvalue of an indecomposable nonnegative matrix, which is based on ideas of geometric programming. In addition to that, we obtain estimates for elements of an indecomposable nonnegative matrix by its spectral radius. The results make it possible...

The next international version of the System of National Accounts will recommend that R&D (Research and Development) expenditures be capitalized instead of being immediately expensed as in the present System of National Accounts 1993. An R&D project creates a new technology, which in principle...
