The use of a spatial model of economic efficiency to predict the most likely outcomes under different fishing strategy scenarios

2021

The current European Union has been progressively implementing since January 2014 a discard ban which includes the obligation to land unwanted catch for certain regulated species and sizes. Although a full enforcement of the landing obligation has a direct impact on discard reduction through more responsible and selective fishing, fishers argue that it will prompt both a decrease in incomes and an increase in working time onboard. Thus, the measure is in a hold in south-western waters due to the difficulties to implement the ban in mixed fisheries This paper analyzes some possible scenarios which fishers could face under the landing obligation. It is shown the construction of a spatial bio-…

Local Green Power Supply Plants Based on Alcohol Regenerative Gas Turbines: Economic and Environmental Aspects

2020

Growing economies need green and renewable energy. Their financial development can reduce energy consumption (through energy-efficient technologies) and replace fossil fuels with renewable ones. Gas turbine engines are widely used in transport and industry. To improve their economic attractiveness and to reduce harmful emissions, including greenhouse gases, alternative fuels and waste heat recovery technologies can be used. A promising direction is the use of alcohol and thermo-chemical recuperation. The purpose of this study is to estimate the economic efficiency and carbon dioxide emissions of an alcohol-fueled regenerative gas turbine engine with thermo-chemical recuperation. The carbon …

Combinatorial Double Auction Radio Resource Allocation Model in Crowd Networks

2018

International audience; Industrial Partners (IPs) with Mobile Network Operators (MNOs) are extending the mobile network infrastructure with Small Cells (SCs) in order to meet the growing mobile traffic demand. Due to the increasing number of telecommunication market competitors and the scarcity of radio resources, static sharing schemes are no more efficient. New dynamic schemes should be considered to meet both user expectations and economic success. In a crowd networking context, we propose in this work a dynamic radio resource scheme based on combinatorial double auctions. The participants in these auctions are the MNOs considered as buyers and the IPs, providers of SCs, considered as se…

Assessment of Tourist Competitiveness by Analysing Destination Efficiency

2006

Recently the notion and the measurement of destination competitiveness have received increasing attention in the economics literature on tourism. The reason for this interest emerges from both the increasing economic importance of the tourist sector and the increasing competition on the tourist market as a consequence of the transition from mass tourism to a new age of tourism that calls for a tailor-made approach to the specific attitudes and needs of tourists. The central subject of this paper - inspired by the conceptual competitiveness model developed earlier by Crouch and Ritchie - concerns the efficiency of tourist site destinations. Using a dataset of 103 Italian regions for the year…

Managerial Ability, Players’ Cultural Diversity, and Sporting and Economic Performance in English Soccer

2012

We use a large homemade database on professional soccer in England to estimate the relevance of managerial ability on performance and the managerial skills in keeping up cultural diversity. The team manager faces a set of very complex tasks. Not only he is the head coach of the soccer team, thus influencing sporting performance, but he can also have an impact on performance, by improving economic efficiency or by limiting the organization innovation in order to foster the creation of organizational routines. The sporting competitive advantage translates into economic and financial performance; therefore the manager is a dominant voice in the financial viability of the club, too. We also mea…

The effect of the launch of bitcoin futures on the cryptocurrency market: an economic efficiency approach

2021

We analyze the economic efficiency of the cryptocurrency market after the launch of Bitcoin futures by means of the Data Envelopment Analysis and Malmquist Indexes. Our results show that the introduction of Bitcoin futures did not affect the economic efficiency of the cryptocurrency market. However, we observe that Bitcoin obtained the highest risk-return trade-off due to its liquidity compared to the rest of cryptocurrencies. Therefore, our paper underlines the support of investors on Bitcoin to the detriment of the rest of cryptocurrencies.

How does seasonality affect water reuse possibilities? An efficiency and cost analysis

2012

Abstract Because of the harsh conditions of water stress and seasonal water demand in many zones, water reuse has emerged as a key alternative for achieving sustainable water management. An efficient performance by wastewater treatment plants (WWTPs) in technical and economic terms favors water reuse. However, seasonality in the flow of wastewater and in the pollutant load may be a determining factor in the efficiency of WWTPs. To evaluate if seasonality affects WWTP efficiency, analytical benchmarking methodology Data Envelopment Analysis (DEA) is used to obtain an average efficiency score for seasonal and non-seasonal plants. Given the importance of extended aeration (EA) and activated sl…

The cost of market power in banking: Social welfare loss vs. cost inefficiency

2007

Abstract This paper analyses the relationship between market power in the loan and deposit markets and efficiency in the EU-15 countries over 1993–2002. Results show the existence of a positive relationship between market power and cost X-efficiency, allowing rejection of the so-called quiet life hypothesis [Berger, A.N., Hannan, T.H., 1998. The efficiency cost of market power in the banking industry: A test of the ‘quiet life’ and related hypotheses. Review of Economics and Statistics 8 (3), 454–465]. The social welfare loss attributable to market power in 2002 represented 0.54% of the GDP of the EU-15. Results show that the welfare gains associated with a reduction of market power are gre…

Tariffs and efficient performance by water suppliers: an empirical approach

2012

Water leaks are an environmental and sustainable issue as well as an economic issue. The objective of this paper is to analyse the efficiency of a sample of Spanish urban water systems by considering water leaks in a network as undesirable outputs. Data envelopment analysis (DEA), an analytical benchmarking methodology, is used to calculate technical and economic efficiency. We also discuss the possible relationship between efficiency and tariffs charged to users. Results show that the possibilities for reducing water leaks in networks are high, thus demonstrating that there is room for savings from an economic and environmental point of view. The assessment of efficiency performance could …
