“…In this last case, however, elasticities are no longer fixed and identical for all the individuals and periods, and they also depend on the quantities of other input factors (Helali & Kalai, 2015).…”

In the last years, European producers of cultured sea bass and sea bream have had to compete strongly among them as well as with Turkish producers to be competitive. One important factor of economic competitiveness is to produce efficiently. For this reason, we have evaluated the technical efficiency of European producers of cultured sea bass and sea bream in the last decade (2008-2017) using the stochastic production frontier (SPF) approach and we have analyzed the effect of some specific-firm factors in firms' productivity. To do this analysis, we have employed a representative sample of 73 European firms producing sea bass and sea bream in the Mediterranean Sea. Data for this analysis was obtained from the ORBIS and EUMOFA databases. The majority of European firms producing cultured sea bass and sea bream in the Mediterranean Sea presented a productivity over 90%, being Cypriot and Greek firms the most productive. We have also found evidence that technical efficiency of these firms is positively related to their location (better environmental conditions in the Eastern Mediterranean Sea) and size (increasing production returns related to a higher level of quality in the making decisions or in the organization of the production process).

This study examines two different fiscal competition games under labor market imperfections. Given that capital moves across regions and affects regional employment, governments must choose the expenditure level and tax rate on such mobile capital by accounting for the effects of fiscal variables on both capital and labor. Therefore, governments may play these games with either the tax rates on mobile capital or with public expenditures. The presence/absence of absentee ownership of capital and employment externalities are significant factors that characterize two distinct Nash equilibria, one that occurs with tax competition and the other with expenditure competition. Contrary to the existing literature, tax rates under tax competition are likely to be lower than those under expenditure competition owing to employment externalities. In some cases, governments prefer to choose government expenditure as their strategic variable rather than the tax rate. The presence of employment externalities motivates governments to use such expenditure as the variable through which it may strengthen strategic effects.

“…The structure of the model takes into account concepts such as economic dispatch, as developed by [90]; the treatment of renewable generation and demand response according to [83,[127][128][129]; the coefficient of elasticity of substitution (CES) outlined by [130]; and CO 2 emission control described by [131], associated with the methodology of the Intergovernmental Panel on Climate Change (IPCC), used to quantify CO 2 emissions at three levels of detail. The main modeling specifications for the proposed methodology are shown in Table 3.…”

A Methodological Proposal for Implementing Demand-Shifting Strategies in the Wholesale Electricity Market

et al. 2022

The energy transition has shown that fossil generation can be complemented with renewable energy and other resources capable of providing flexibility to the energy system’s operation, in compliance with the wholesale electricity market’s rules. This paper proposes a market-based methodology for introducing flexible demand in the energy dispatch , optimizing the scheduling of electricity system operation in the short-term, and considers the challenge of implementing an incentive scheme for participants in demand-response programs. The scheme includes the criteria of the elasticity of substitution and a renewable energy quota. This methodology is focused on a strategic demand shift to minimize the cost of supply; increase the dispatch of renewable energy; control CO2 emissions; and satisfy the generation, demand, and transmission operating constraints. These conditions encourage the development of a simulation tool that allows a sensitivity analysis to aid decision-making by operators and agents. The proposed methodology optimizes the operational cost of generation supply and specific performance indicators to determine the percentages of demand shift, the amount of CO2 emissions, the ratio of unserved power, the demand benefits obtained from an incentive scheme, and the natural market behavior.
