Adjustment costs, uncertainty, and the theory of investment: the case of non-renewable natural resources
1992
Abstract This paper examines the effects of mineral price and extraction cost uncertainty on the investment program of a competitive resource-extracting industry that faces convex costs of adjustment. The results show that depletion of mineral reserves will slow down if the marginal adjustment cost function is concave or linear, whereas the effect will be ambiguous if the function is convex.
Analysis of intermittent supply systems in water scarcity conditions and evaluation of the resource distribution equity indices
2007
Generally, urban water distribution shortage situations are solved by introducing discontinuous service and rationing the available water resources. This approach is widely adopted, not only in developing countries but also in developed ones, for solving short term scarcity conditions which can be caused by unpredicted drought periods. Intermittent distribution has the advantage of requiring small financial efforts but it leads to network operating conditions that are very far from the usual design ones. With the aim to analyse and describe the water supply network behaviour in intermittent conditions, a network hydraulic model has been set up in which both user and manager dependent regula…
The plants of the future. : genome editing in biotechnology
2021
The evolution of life has led to the formation of complex systems where plants are essentials. Homo sapiens’ success is based on its ability to obtain food. In what remains of this century, the world population will increase by a quarter of the current total, reaching 10 billion people. This is itself a major challenge, amplified by the environmental conditions resulting from global change and the threat to sustainability derived from the use of the planet’s natural resources. Thus, we wonder if we will be able to respond to this challenge and, to that end, how the plants of the future should look. Recent advances in sequencing techniques allow us to identify genomes at a low cost, and geno…
ECONOMIC EVALUATION OF AQUACULTURE INVESTMENTS UNDER CONDITIONS OF RISK AND UNCERTAINTY IN THE MEDITERRANEAN SEA
2014
This study aims to analyze, from a technical and ec onomic point of view, the choice between alternative investments in aquaculture under condit ions of risk and uncertainty. In particular, a comparative analysis has been conducted between an inshore and an offshore farm producing European sea bass in the Mediterranean Sea. The app lied model refers to the theory of subjective probability, assigning a different probability to e xpected incomes during the investment period. Resul ts show an economic convenience of inshore with respect to offshore farming.
DOMESTIC MATERIAL CONSUMPTION INDICATOR AND NATURAL RESOURCES: A EUROPEAN ANALYSIS OF THE ENVIRONMENTAL KUZNETS CURVE
2014
The study investigates the relation between per capita Domestic Material Consumption indicator (DMC) and per capita income. Economic literature focuses mainly on air, water and land pollution while we consider as environmental degradation the consumption on natural resources extracted from the environment. Using a cross– European panel of countries over the period 2000-2011, our results confirm the absence of an Environmental Kuznets Curve (EKC) between per capita DMC and per capita GDP both for EU-27 vs. 30 European countries and for Western vs. Eastern European countries. The turning points are so high that it is present a monotonic increasing relation between DMC indicator and GDP.
A renewable energy mix to supply small islands. A comparative study applied to Balearic Islands and Fiji
2019
Abstract Power plants supplied by renewables are expanding around the world, increasing the sustainability of the energy sector. In this context, small islands are heavily reliant on fossil fuels. However, this paper shows that the same problem can be found also in small islands belonging to developed countries. To increase the energy sustainability of small islands, the authors assembled a simplified mathematical approach to evaluate the potential electricity production, exploiting the local available energy sources: solar, wind and sea wave. The mathematical model requires few information in input, such as climatic data about the local energy sources and technical features on the selected…
THE PRODUCTIVITY AND COMPETITIVENESS PROBLEMS OF LATVIA IN THE CONTEXT OF THE GLOBAL ECONOM
2019
In the article the dynamics of labour productivity in Latvia was analyzed and the factors which have influenced the labour productivity in last 5 years were detected, to compare the productivity in Latvia with EU average. Analysing changes in productivity and labour costs in Latvia from 2013 till 2017, we can see that growth of labour costs exceeds the growth of productivity by more than 2 times in both, tradable sector and total economy. Slow growth in productivity compared with the labour and other production expenses lead to an increase in the price of final goods and services, which negatively corresponds with producers’ competitiveness in both internal and external market. Also, the at…
An Opportunity for the Agricultural Sector: The Renewable Energy Sources

Prospects of Innovative Development of Agricultural Production on the Example of the Republic of Kazakhstan
2021
The relevance of the study is conditioned by the need to revise the methods of farming with a focus on the use of innovative technologies to improve the quality and quantity of output. The purpose of the study is to analyse the problems and prospects of agricultural production in the Republic of Kazakhstan to create a comprehensive innovative model for the further development of the agro-industrial sector. The study of the prospects for the modernised improvement of the agro-industrial complex of the Republic of Kazakhstan was carried out in three stages based on the functional and logical, systemic, and structural approaches using methods of analysis, synthesis, comparison, systematisation…
