In this article, we investigate the existence of long-run common trends between imports and remittances in 11 Central and Eastern European countries which are part of the European Union. Using the Engle–Granger two-step procedure, we determine that for all countries in our sample there are no long-run common trends (no cointegration) between imports and remittances. However, the results are mixed when running a Granger causality test. For nine countries, we can establish either a bidirectional or unidirectional Granger causality, indicating that past values of one variable have predictive content on the other variable. In two countries, there is no Granger causality between imports and remittances.  相似文献

This article predicts the daily movement of monthly foreign exchange (FX) rate volatility using a linear combination of a time-series model and implied volatilities from options. The focus is on analysing the FX volatilities in three developing economies (the Brazilian real (BRL), the Indian rupee (INR) and the Russian ruble (RUB)) against the US dollar (USD). The empirical exercise utilizes two time-series models, mixed data sampling (MIDAS) and GARCH. The analysis indicates that for both developed and developing economies the predictive power of MIDAS and that of GARCH is comparable. Further on in this article, we will ascertain whether the relationship between realized and implied volatility is fundamentally different in the case of developing economies from that among developed economies. Thus, we compare the pairs USD/BRL, USD/INR and USD/RUB against EURO/USD and USD/Japanese yen to determine the information content and predictive power of implied volatilities. Plots of the MIDAS coefficients show that the volatility is more persistent in developing economies than in developed economies.  相似文献

Abstract. The purpose of this article is to evaluate the importance of different immigration policies associated with corresponding migration backgrounds, command of national languages and intergenerational mobility, for the PISA school performance of teenagers living in European countries (France, Finland, Germany, United Kingdom and Sweden) and traditional countries of immigration (Australia, Canada, New Zealand and the US). Econometric results show that the influence of the socioeconomic background of parents differs strongly across nations, with the highest impact found for Germany, the UK and US, whereas intergenerational transmission of educational attainment is less likely in Scandinavian countries and in Canada. Moreover, for all countries our estimations imply that for students with a migration background a key for catching up is the language spoken at home. We conclude that educational policy should focus on integration of immigrant children in schools and preschools, with particular emphasis on language skills at the early stage of childhood.  相似文献

Nature‐based solutions (NBS) are becoming increasingly crucial as NBS brings diverse health‐related benefits to travelers and workers in the tourism business sector. This research explored the influence of green atmospherics as NBS on airport occupants' mental health value, image, and loyalty generation processes. A quantitative approach with a field survey method was employed. A structural equation modeling and metric invariance test were used as data analysis technique. Our empirical result revealed that green atmospherics as NBS significantly improve the occupants' mental health value and image of the airport, and these variables contribute to their loyalty enhancement for the airport. The effect of green spaces and natural surroundings on loyalty was maximized through mental health value and image. In addition, the linkages from natural surroundings to mental health value and image were stronger in the visitor group whereas the mental health value—loyalty relation was stronger in the worker group.  相似文献

Romania has the potential of resources, labor and real capacity to adapt to the gait of a global economic competition. But it required a long term policy and environment which could support this potential value. If not, we will risk turning into a consumer economy, consumption will not be funded on internal production and become supplier of labor services for peripheral. In the context of economic crisis, Romanian furniture retains its significant competitive advantages, including the price in export markets. The most important markets for exporters of furniture from Romania are Ukraine and Russia, markets with great potential, but affected by problems such as devaluing local currencies, and recently, imposing new duties.  相似文献

Objective: To assess the cost-effectiveness (CE) of the originator follitropin-α (Gonal-F) in patients undergoing a medically assisted reproduction (MAR) program in comparison to its biosimilars Bemfola and Ovaleap in a French context.

Methods: A CE model was developed for France with a National Health Service (NHS) perspective. Clinical, safety, and dosage data were derived from pivotal clinical trials that compared Gonal-F to Ovaleap and Bemfola. Costs pertaining to drugs, hospitalizations, specialist visits, and examinations were retrieved from the French Programme de Médicalisation des Systèmes d'Information (PMSI) hospital database, literature review, and French clinical experts using 2017?Euro tariffs. In order to test the robustness of results, deterministic one-way sensitivity analyses were carried out on the main variables to assess the impact of treatment cost, probability of birth, ovarian hyperstimulation syndrome (OHSS) rates, and dosage.

Results: The average incremental cost per live birth with OHSS and without OHSS was €259.56 and €278.39, respectively, for Gonal-F compared to the pooled biosimilars (i.e. Ovaleap and Bemfola). GONAL-F had an incremental efficacy of 0.06 over the pooled biosimilars. The incremental cost-effectiveness ratio for Gonal-F with OHSS ranged from €3,274.80 to €4,877.76 compared to the pooled biosimilars, owing to the additional live births reported with Gonal-F. Sensitivity analyses also supported results from the base case analyses, with Gonal-F being cost-effective or the dominant strategy in most cases.

Conclusion: Gonal-F seems to be a cost-effective strategy compared to its biosimilars Ovaleap and Bemfola, irrespective of the incidence of OHSS events, but further data are needed to confirm these results.  相似文献

The paper is one of the first empirical attempts that builds on the moral dilemmas and group rationality literature to explore the way in which group composition with respect to group members’ individual choices in moral dilemmas and social influence processes impact on group moral choices. First individually and then, in small groups, 221 participants were asked to decide on 10 moral dilemmas. Our results show that emergent group level utilitarianism is higher than the average individual utilitarianism, yet, lower than the highest individual utilitarianism within groups. We also show that average individual utilitarianism positively predicts group utilitarianism while group fragmentation in individual utilitarianism has a negative effect on group utilitarianism. Next to group composition, minority influence processes explain additional variance in group utilitarianism, cognitive dissent having a positive influence, while normative deviance a negative influence on group utilitarianism. Majority influence has no significant influence on group utilitarianism. Finally, our results show that the relationship between group fragmentation in individual utilitarianism and emergent group utilitarianism is mediated by the two forms of minority influence.  相似文献

The globalization process is affecting a lot the economical environment and in many spheres has characterized the last decade of the twentieth century; accounting and auditing as information tools of the real economy are no exception. This paper introduces the analysis of the ongoing process of harmonization of the qualification to audit at a global level. The aim of the paper is to throw light on the processes of harmonizing auditing and accounting on a global basis, an issue that is of considerable debate at the current time both in the accountancy profession and in academia. The paper is structured is several chapters. In the first chapter entitled "Process of globalization and accounting evolution" the authors are presenting the steps in the main harmonization process and its major players during the last decades. The engine of internationalization seems to be the Anglo-Saxon accounting systems where the globalization issue was always very important. In the second chapter "Literature review" the authors are presenting some articles linked with the subject of our paper. In the third chapter "Harmonization of the qualification to audit" the authors are presenting need of "global qualification" in accounting and audit profession. In the fourth chapter "The field of global accountancy education", the authors are presenting the history of the adopting by the international organizations sustainable global education curricula in the field of accounting and audition profession. There the authors are underlying the role of Intergovernmental Working Group of Experts on International Standards of Accounting and Reporting International, which is considered to develop a "model curriculum" for a global accountancy qualification. Also is presented the IFAC's Education Committee's results and also the ACCA program in educational field. The chapter "Forces which are ruling the regulation process" is presented the IASC/IASB and the European directives in harmonization process. On the chapter "Global accountancy education" the authors are presenting the threats of using the need of "international qualification in audit" by developed countries as a tool of exploitation, using it as "cultural capital" for sale to developing countries (See the ACCA mechanism). Also the authors are presenting the IFAC role on building up international accounting curricula, which can be implemented through its members all over the world. The conclusions are trying to emphasize the steps which the accounting education needs to be followed in Romania due to the international evolutions.  相似文献
