Coordination of Wage Bargaining, Exchange Rate Stability and External Adjustment
2016
The literature on the determinants of the rate of current account reversion has been limited to examining the role of exchange rate regimes. We propose that the degree of coordination of wage bargaining affects the speed of current account adjustment. Our point estimates are economically and statistically significant, suggesting that fragmented firm-level wage bargaining facilitates external adjustment. We also find a strong negative interaction between the effects of coordination of wage bargaining and exchange rate stability on the rate of current account reversion.
The Impact of Exchange Rate Fluctuations on Profit Margins: The UK Car Market, 1971–2002
2007
We investigate the impact on profit margins of exchange rate fluctuations in order to examine optimal pricing policy by source countries in the UK car market. We first estimate a nested logit deman...
Congestion management rules and trading strategies in the Spanish electricity market
2009
Abstract This paper analyses the economic incentives embodied in the rules governing the resolution of transmission constraints in the Spanish wholesale electricity market and the way these incentives may have influenced on the trading behaviour of both the generators and the demand side. The evidence obtained is consistent with them responding to these incentives. In particular, buyers would respond to the way congestion costs are billed to them by abandoning the daily market in favour of the intraday market as far as possible. Additionally, some strategic generators may have been prompted the system operator to require them to inject electricity into the system to solve network congestion…
An ACE Wholesale Electricity Market Framework with Bilateral Trading
2011
In this paper, an agent-based simulation model for a hybrid power market structure is presented. A bilateral transaction mechanism is combined with a uniform-pricing auction settlement in order to isolate the impact of medium-term bilateral contracts on market power and spot prices in a competitive wholesale market setting. First we describe the negotiation method for bilateral trading of energy and then introduce a new approach for bidding in the DA market based on the load duration curve. We find that, despite the conventional concerns, the foreclosure effect produced by the bilateral agreement between a generation and a retail business will not necessarily lead to higher prices, and will…
A Problem of Optimization in a Case of Foreign Investment
2000
The aim of the paper is to solve an optimization problem in an economic system with a central bank and a set of private agents. Each agent aims to maximize her expected utility, with rational expectations and being risk averse. The agents follow a profitability-risk criterium to face the portfolio diversification problem between foreign or domestic investment. An explicit formula for the optimal amount of foreign investment as a function of the expected exchange rate and an explicit formula for the exchange rate are obtained. These formulas show the hard influence of the expected exchange rate, the variance and the risk aversion on the agents’ decisions.
Women in management in the Arab context
2008
PurposeThis paper aims to explore the position of Arab women in management by examining the existing research on gender and management in the Arab region in order to obtain an overall picture of the advancement of Arab women in their professional lives, point out coherent clusters of research and identify knowledge gaps in existing research.Design/methodology/approachThe study conducts a content analysis of academic articles in order to provide a quantitative as well as qualitative thematic overview of the topics emerged from the literature.FindingsThe statistical analysis of researches shows that, the topic of women in management is gaining more importance. The thematic overview of researc…
The implementation of mindfulness in healthcare Systems: a theoretical analysis
2014
Abstract Objective Evidence regarding the efficacy of mindfulness-based interventions (MBIs) is increasing exponentially; however, there are still challenges to their integration in healthcare systems. Our goal is to provide a conceptual framework that addresses these challenges in order to bring about scholarly dialog and support health managers and practitioners with the implementation of MBIs in healthcare. Method This is an opinative narrative review based on theoretical and empirical data that address key issues in the implementation of mindfulness in healthcare systems, such as the training of professionals, funding and costs of interventions, cost effectiveness and innovative deliver…
Tax burden borne by electricity and mining companies in Peru during 2010-2015 period
2018
O objetivo principal da pesquisa é quantificar a pressão fiscal suportada pelas empresas elétricas e de mineração que operam no Peru, no período 2010-2015, de tal forma que a existência de diferenças entre os dois setores econômicos analisados possa ser avaliada. Para este propósito, é apresentada uma descrição do setor elétrico e de mineração, bem como a evolução e influência que exercem sobre o crescimento econômico do Peru. Como elemento importante da investigação, foi realizada uma análise do arcabouço jurídico tributário que regula as atividades das empresas dos dois setores analisados, em especial, no tocante ao Imposto de Renda. O referencial teórico incorpora as principais referênci…
Assessment in vitro of cytogenetic and genotoxic effects of propolis on human lymphocytes
2012
We evaluated the genetic damage by ethanolic extract of propolis (EEP) induced to human lymphocytes which were exposed to increasing concentrations (0–2000 μg ml−1). The results indicated that EEP reduced significantly the mitotic index (MI) and proliferation index (PI) when high concentrations of EEP were used. Sister chromatid exchange (SCE) rates indicated that EEP could have genotoxic effects at high concentrations. Exposure of the cells to the amount of ethanol used as solvent did not alter either the MI and cell proliferation kinetics (CPK), or the rate of SCE. The results showed: (a) statistical increase in the percentage the cells with CAs and in the frequency of SCE at the highest …
Radioprotective activity and cytogenetic effect of resveratrol in human lymphocytes: An in vitro evaluation
2012
Trans-resveratrol is a natural occurring polyphenol, obtained from grapes and other berries. This compound has shown antioxidant, anti-inflammatory, immunostimulant or anti-carcinogenic properties. Our aim was to evaluate the radioprotective efficacy, in vitro, of trans-resveratrol against radiation-induced chromosomal damage and to study the genotoxicity and cytotoxicity of this polyphenol in cell cultures without irradiation. The study was carried out by the pre-treatment of human lymphocytes at concentrations from 0 to 219μM of trans-resveratrol. The results showed that all concentrations tested reduced radiation-induced chromosomal damage compared with cells with any treatment. Maximum …
