Motivated by the new auction format in the England and Wales electricity market, as well as the recent debate in California, we characterize bidding behavior and market outcomes in uniform and discriminatory electricity auctions. Uniform auctions result in higher average prices than discriminatory auctions, but the ranking in terms of productive efficiency is ambiguous. The comparative effects of other market design features, such as the number of steps in suppliers' bid functions, the duration of bids, and the elasticity of demand are analyzed. We also consider the relationship between market structure and market performance in the two auction formats. 相似文献

The OECD proposes to kill two birds with one stone in Russiaby simultaneously improving fiscal federalism, and using thefinancial reform process to press for full market liberalisation.This paper scrutinises the initiative and finds it wanting becausethe consensus reforms advocated conflate the re-centralisationof fiscal authority with optimal ownership, property rightsand effective market building, perpetuating the illusion thatthere are no bad market systems. The G-7 and Putin must do better.Yeltsin's mis-privatisation and mis-liberalisation, which spawnedrent seeking, asset stripping, asset seizing and a disregardfor profit maximising from current operations, have proved tobe path dependent and need to be rectified. Putin's increasinglyvisible efforts to rein private property rights must also betaken into account in designing on optimal fiscal federalistregime. 相似文献

Boards and Sustainability: the Contingent Influence of Director Interlocks on Corporate Environmental Performance 下载免费PDF全文
Natalia Ortiz‐de‐Mandojana Juan Alberto Aragon‐Correa 《Business Strategy and the Environment》2015,24(6):499-517
This paper highlights the importance of a firm's board with respect to sustainability issues by analysing the relationship between director interlocks, i.e. directors who simultaneously belong to the boards of directors of several companies, and a firm's environmental performance. The previous literature has focused on the influence of firm‐level resources on corporate environmental performance. This study utilizes insights from a resource‐based view and research on social capital to demonstrate that the environmental performance of a firm is also influenced by the difficult‐to‐imitate capabilities that are embedded in the network relationships of its directors. Our results support a contingency perspective of the social capital theory that finds that director interlocks are positively connected with the environmental performance of a firm in two specific situations: (1) when the firm is linked to a larger parent company and (2) in cases of low and high levels of interlock diversity.

We propose an Income Contingent Loan that defers the payment of university fees and charges a fixed proportion of gross income for 30 years or until the debt is written off. Under these conditions, some participants in the scheme will have insufficient income to fully repay their loan balances. The deficit will be covered by the taxpayer, who ultimately bears the risk of investing in higher education. We then propose to transfer this risk to the student by adding a mandatory personal insurance policy to the individual loan. We calculate the premium required for the system to break even in Spain when everybody pays the insurance cost. Alternatively, the payment of the premium can be deferred, adding it to total debt. Then, some participants in the scheme will have insufficient income to even pay the insurance cost, and the premium needs to be increased to maintain the sustainability of the program. Although these mechanisms imply redistribution towards borrowers who end up being low earners, we show that middle-income individuals contribute a higher proportion of their incomes to covering for those unable to repay. To provide the system with more internal progressivity, we propose to impose a minimum period of repayment. 相似文献

This paper deals with the relationship between the balance of trade and the exchange rate in the US/UK case. Many authors have studied this issue for many countries, but despite the intensive research, there is still no agreement about the effectiveness of currency devaluation to increase a country's balance of trade. We first analyse the relationship between the two variables using unit roots and co-integration methods, and the results are ambiguous. We try a new approach based on fractional integration. The unit root hypothesis is rejected in case of the trade balance in favour of smaller orders of integration, while this hypothesis is not rejected for the exchange rate. Thus, the two series do not possess the same order of integration. We sort this problem out by taking the exchange rate as an exogenous variable, and including it in a regression model where the residuals might follow a fractionally integrated model. 相似文献

Aim: To evaluate the burden of uncontrolled gout by examining estimated costs and cost drivers.Materials and methods: Data from the 2012 and 2013?US National Health and Wellness Survey (NHWS; 2012 NHWS, n?=?71,157 and 2013 NHWS, n?=?75,000) were utilized in this study. Based on self-reported gout diagnosis and gout symptoms, respondents were categorized into three groups: controlled gout (n?=?344), uncontrolled gout (n?=?2,215), and non-gout controls (n?=?126,360). Chi-square tests and one-way analysis of variance (ANOVAs) were used to assess group differences on work productivity loss, healthcare resource utilization, and costs. Zero-inflated negative binomial regressions were used to assess the burden of uncontrolled gout on total costs after controlling for covariates.Results: Patients with uncontrolled gout had higher presenteeism, overall work impairment, activity impairment, and number of emergency department visits than those with controlled gout or controls. Overall, uncontrolled gout patients had both higher indirect and total costs compared to patients with controlled gout. After controlling for confounders, those with uncontrolled gout had higher total costs than controlled gout respondents and non-gout controls; there was no significant difference in total costs between patients with controlled gout and non-gout controls.Limitations: Results were based on cross-sectional, self-reported data, making causal inferences more uncertain. Additionally, sample size was small for controlled-gout respondents. Lastly, sampling weights were not used, thus potentially limiting generalizability.Conclusion: Gout can be an expensive condition, particularly if it is not properly controlled. This study provides support that controlling symptoms (e.g. flares) can reduce the economic and societal burden of gout. Therefore, more attention needs to be paid to effective management of gout symptoms. 相似文献

Risk and return: Long-run relations,fractional cointegration,and return predictability 总被引:1,自引:0,他引:1

Univariate dependencies in market volatility, both objective and risk neutral, are best described by long-memory fractionally integrated processes. Meanwhile, the ex post difference, or the variance swap payoff reflecting the reward for bearing volatility risk, displays far less persistent dynamics. Using intraday data for the Standard & Poor's 500 and the volatility index (VIX), coupled with frequency domain methods, we separate the series into various components. We find that the coherence between volatility and the volatility-risk reward is the strongest at long-run frequencies. Our results are consistent with generalized long-run risk models and help explain why classical efforts of establishing a naïve return-volatility relation fail. We also estimate a fractionally cointegrated vector autoregression (CFVAR). The model-implied long-run equilibrium relation between the two variance variables results in nontrivial return predictability over interdaily and monthly horizons, supporting the idea that the cointegrating relation between the two variance measures proxies for the economic uncertainty rewarded by the market. 相似文献

AbstractAims: This study aimed to characterize the burden of Parkinson’s disease (PD) by examining health-related quality-of-life (HRQoL), impairments to work productivity and daily activities, healthcare resource use, and associated costs among Japanese patients with PD.Materials and methods: This retrospective cross-sectional study used data from the 2009–2014 Japan National Health and Wellness Survey (NHWS) (n?=?144,692). HRQoL (Short Form 36-Item Health Survey version 2), impairments to work productivity and daily activities (Work Productivity and Activity Impairment Questionnaire), healthcare resource utilization, and annual costs were compared between respondents with PD (n?=?133) and controls without PD (n?=?144,559). The effect of PD on outcomes was estimated using propensity score weighting and multivariable regression models.Results: HRQoL was lower in patients with PD compared to the control group, with reduced physical (41.3 vs 51.3) and mental (35.7 vs 45.4) component summary scores and health state utility scores (0.62 vs 0.77; p?<?.001 for all). Patients with PD also reported higher levels of absenteeism (19.3% vs 3.3%), presenteeism (45.2% vs 18.5%), overall work impairment (52.8% vs 20.3%), and activity impairment (49.6% vs 20.8%) than controls without PD (p?<?.001 for all). In addition, patients with PD had higher healthcare resource utilization, direct (¥3,856,921/$37,994 vs ¥715,289/$7,046), and indirect (¥2,573,938/$25,356 vs ¥902,534/$8,891) costs compared with controls without PD (p?<?.001 for both).Limitations: Data were cross-sectional and did not allow for causal inferences. Although the NHWS demographically represents the Japanese adult population, it is unclear whether it adequately represents the adult population with PD in Japan.Conclusions: PD was associated with poorer HRQoL, greater work productivity loss, and higher direct and indirect costs. The findings suggest that an unmet need exists among patients with PD in Japan. Improving PD treatment and management could benefit both patients and society. 相似文献
