We contribute to the literature by identifying and accurately measuring the drivers of American depositary receipt (ADR) returns contemporaneously across various global time zones. We consider ADRs as two inherently distinct asset classes – stocks and currencies – bundled into one. Throughout, we use a relatively refined, focused, and synchronized minute-by-minute data set on ADRs and all other variables. ADRs from all countries with regular trading hours that overlap with those of the US are considered individually and in clusters. We analyze the interplay of several factors that influence ADRs pricing patterns. Further, we investigate whether such patterns vary by currency, ADR, industry, and emerging/developed market classifications. Our findings indicate that synchronized returns on underlying shares comprise 68.5–74% of the explained returns in ADRs. The remaining 31.5–26% of returns are generated by movements in currency rates. These results are robust across the several models and estimation methods employed. Our findings also show persistent small price discrepancies between ADRs and dollar-adjusted underlying shares on a minute-by-minute basis, implying possible arbitrage opportunities. However, we conclude that trading and ADR conversion costs render such opportunities unattractive.  相似文献

This article examines the relationship between the monetary policy implemented by the Central Bank of Brazil and the stock market. We implement event study analysis and analyze the effect of the anticipated and unanticipated components of monetary policy decisions on the returns of the IBOVESPA index and 53 stocks. We find that monetary policy has a significant effect on the stock market, but is only responsible for a small proportion of market variation. The analysis at the sector level with expected returns identifies that the financial sector is the most affected by this policy, whereas with excess returns only industrial goods are significantly affected. Moreover, individual assets respond in a rather heterogeneous fashion to monetary policy; however, when we look at excess returns, we identify a reduction in the intensity and in the number of companies impacted by monetary policy. Finally, the monetary shock is explained by unanticipated variations in the unemployment rate, in the Industrial Production Index, in the General Market Price Index, and in the Broad Consumer Price Index.  相似文献

Two-part models based on generalized linear models are widely used in insurance rate-making for predicting the expected loss. This paper explores an alternative method based on quantile regression which provides more information about the loss distribution and can be also used for insurance underwriting. Quantile regression allows estimating the aggregate claim cost quantiles of a policy given a number of covariates. To do so, a first stage is required, which involves fitting a logistic regression to estimate, for every policy, the probability of submitting at least one claim. The proposed methodology is illustrated using a portfolio of car insurance policies. This application shows that the results of the quantile regression are highly dependent on the claim probability estimates. The paper also examines an application of quantile regression to premium safety loading calculation, the so-called Quantile Premium Principle (QPP). We propose a premium calculation based on quantile regression which inherits the good properties of the quantiles. Using the same insurance portfolio data-set, we find that the QPP captures the riskiness of the policies better than the expected value premium principle.  相似文献

The financial crisis experienced by many countries since 2008 has given new importance to private finance initiatives (PFIs) for providing public services. This paper analyses the relationships between multiple public and private sector actors participating in a PFI in the healthcare sector in order to better understand the motives and behaviour of public and private sector partners. High levels of trust and the active participation of a regulatory body were found to be significant factors in terms of creating a partnership that benefits all sides.  相似文献

When pursuing goals, consumers often face setbacks that force them to reevaluate their goals. Yet, current goal theory offers limited explanations for how people respond to recurring challenges and disengage from their goals. Through five experiments investigating three primary theoretical aims, this research extends the field's understanding of action crisis, a possible goal pursuit stage marked by internal conflict over whether or not to continue, and investigates it in consumption contexts such as patient–physician relationships, weight loss diets, and environmentally friendly purchasing. Experiments 1A–1C show that consumer action crisis encourages more disengagement‐related and less continuation‐supportive cost–benefit thinking than nonproblematic action phase. Experiment 2 replicates this cognitive shift, and connects action crisis to diminished goal‐related evaluations and weakened commitment. Experiment 3 further clarifies action crisis’ influence on consumer goal pursuit by revealing decreased cognitive and behavioral engagement that does not involve a shift in construal level when compared to action phase consumers. Extending understanding of action crisis as a possible mindset and action phase, these five experiments advance goal disengagement theory by connecting changes in cognition, motivation, and behavior to action crisis.  相似文献

The recent economic literature has largely investigated sustainability in the provision of public utilities, highlighting the role of governance models in the determination of economic results. Little attention however has been devoted to the social and environmental dimensions of sustainability. In Italy, a long-lasting debate on governance structures in the water sector has been fuelled by scholars and policymakers for more than 30 years, whereas the first (and unique) experiment involving the return of full public management in water provision is taking place in the city of Naples. The present work analyses this peculiar case study, aiming to assess the effects of a major governance shift that occurred in the early 2010s—that is, decorporatisation—in terms of economic, social and environmental sustainability. We resort to a bundle of qualitative and quantitative techniques to address the research question and our exploratory results suggest that decorporatisation was overall beneficial: Although little changed in terms of economic sustainability, the social and environmental dimensions benefitted from the shift in governance.  相似文献

This study aims to examine the mediating role of internal lean practices (ILPs) on the relationship between entrepreneurial orientation and triple bottom line performance (i.e. environmental, social, and operational performance). We examine Chile, which represents a vibrant economy and one of the world's most productive entrepreneurship ecosystems but with a history of socio‐economic inequalities and strong profit‐driven pressures to overextract natural resources. The study is based on a questionnaire related to manufacturing sent to 112 companies in Chile. The proposed relationships are analysed through structural equation modelling. The results indicate that ILPs fully mediate the effect of entrepreneurial orientation on environmental performance and social performance and partially mediates the effect of entrepreneurial orientation on operational performance. Our study extends the literature by explaining that entrepreneurial orientation builds and strengthens ILPs for creating triple bottom line competitive advantage.  相似文献

This paper analyzes the relationship between the gender of mayors in Spanish local government and different budget items. It uses a sample of local budgets for 8,112 town councils between 2002 and 2010, totaling 64,361 observations. The Spanish context is characterized by decentralization of public responsibility to a greater extent than in neighboring countries, feeding the debate on the operational efficiency of local government and the importance of gender in public management. Results show that councils with women mayors have lower annual interest and debt repayment obligations and have higher expenditure on security, protection, and social promotion. Thus, the presence of women in politics may serve to improve councils’ economic situations, which is necessary not only for social justice but also for economic efficiency. In addition, in councils with more inhabitants, women mayors are more common, but women are less likely to occupy the office for longer periods.  相似文献
