Regional political climate has become an increasingly significant force influencing travel behaviour in many tourist destinations. This paper attempts to address impacts of regional political stability on Russian inbound tourism into Spain within a demand model framework and using a cointegration approach. The results show that visa openness as well as political instability and civil unrest in substitute destinations attract more Russian tourists, boosting economic growth and reducing unemployment rates in Spain. On the contrary, international political confrontation results in disadvantage to Russian tourism demand to Spain.  相似文献

Many projects are currently conducted in international businesses in which cultural issues play an important role. In‐depth analysis of the risks associated with the unknown of this type of issues offers companies a better understanding of how to focus their marketing tools to be more effective, and provides project managers with strategies to improve customer relationships. Hofstede's Cultural Dimensions and Meyer's Culture Map have demonstrated that every society possesses distinguishing features. These cultural theories serve as foundation for including the category of culture in a proposed Cultural Risk Breakdown Structure. Through a literature review, risks associated with cultural differences are identified in projects executed in Africa, China, and the Middle East. By linking these risks to cultural dimensions, it is possible to identify the psychological competences framework in international businesses. Therefore, the aim of this paper is to create not only a comprehensive record of these risks but also a list of the new skills and competences that project managers must possess to improve client satisfaction and make decisions in a cross‐cultural environment. By considering the association between psychological aspects and cultural issues, this analysis will be of considerable benefit for improving relationships in international contexts.  相似文献

In this study, we analyze the impact in Brazil of a tax on external capital flows called “Imposto Sobre Operações Finaceiras” (IOF), by following data on a monthly basis from 2007 to 2013. Our goal is to determine whether a change in tax legislation can produce significant effects on the pattern of financial inflows from abroad. Using univariate structural models, our results show that changes in the IOF produced structural breaks on foreign portfolio investments.  相似文献

The stabilization of inflation was conquered in the mid-1990s, but since then the Brazilian economy has not shown a stable growth trend. This article discusses how the maintenance of a high interest rate in Brazil has affected growth through its impact on investment decision. In a macroeconomic environment with a relatively high degree of uncertainty, decisions to accumulate capital rely heavily on retained earnings and are negatively affected by the persistent high level of interest rates. Our econometric exercise reveals that the interest rate is the most important variable to explain the investment rate, and that financialization negatively impacts physical capital accumulation.  相似文献

In this paper, we estimate generalized autoregressive conditional heteroskedasticity (GARCH) and vector autoregressive (VAR) models to examine whether investor sentiment impacts the returns and volatility of various U.S. Dow Jones Islamic equity indices. The results from GARCH estimations show that changes in investor sentiment are positively correlated with the returns of the Shari’ah-compliant market portfolio. In addition, we find similar results for the three Shari’ah-compliant firm-size portfolios (i.e., large-, medium-, and small-cap). However, this relationship is stronger for harder to arbitrage Shari’ah-compliant stocks; that is, investor sentiment has a greater influence on small-cap equities. Additionally, estimations from the vector autoregressive model confirm the aforementioned results. In terms of volatility, GARCH estimations suggest that bullish shifts in investor sentiment in the current period are accompanied by lower conditional volatility in the ensuing period. In general, our findings suggest that as noise traders create more risk the market seems to reward them with higher expected returns.  相似文献

Execution traders know that market impact greatly depends on whether their orders lean with or against the market. We introduce the OEH model, which incorporates this fact when determining the optimal trading horizon for an order, an input required by many sophisticated execution strategies. This model exploits the trader's private information about her trade's side and size, and how it will shift the prevailing order flow. From a theoretical perspective, OEH explains why market participants may rationally “dump” their orders in an increasingly illiquid market. We argue that trade side and order imbalance are key variables needed for modeling market impact functions, and their dismissal may be the reason behind the apparent disagreement in the literature regarding the functional form of the market impact function. We show that in terms of its information ratio OEH performs better than participation rate schemes and VWAP strategies. Our backtests suggest that OEH contributes substantial “execution alpha” for a wide variety of futures contracts. An implementation of OEH is provided in Python language.  相似文献

Many companies relay on contractors to execute different tasks of the value chain. This paper develops an agency model subject to moral hazard to study the general structure of the contract offered by a firm (the principal) to several contractors (agents) that perform the same task. A Generalized Least Squares regression tests the model with a panel data of 58 carriers that work for a shipper in Santiago, over 93 weeks. The regression verifies that the principal rewards some performance dimensions, but neglects others. The regression also confirms that contracting prices are sensitive to the alternatives available for the company and the contractors.  相似文献

Abstract

Background/objective: Although biosimilar drugs may be cheaper to purchase than reference biological products, they may not be the most cost-effective treatment to achieve a desired outcome. The analysis reported here compared the overall costs to achieve live birth using the reference follitropin alfa (GONAL-f) or a biosimilar (Ovaleap) in Spain, Italy and Germany.

Methods: Patient and treatment data was obtained from published sources; assisted-reproductive technology, gonadotropin, follow-up and adverse-event-related costs were calculated from tariffs and reimbursement frameworks for each country. Incremental cost-effectiveness ratios (ICERs) were calculated from the difference in costs between reference and biosimilar in each country, divided by the difference in live-birth rates. Mean cost per live birth was calculated as total costs divided by the live-birth rate.

Results: The published live birth rates were 32.2% (reference) and 26.8% (biosimilar). Drug costs per patient were higher for the reference recombinant human follicle-stimulating hormone in all three countries, with larger cost differences in Germany (€157.38) and Italy (€141.50) than in Spain (€22.41). The ICER for the reference product compared with the biosimilar was €2917.47 in Germany, €415.43 in Spain and €2623.09 in Italy. However, the overall cost per live birth was higher for the biosimilar in all three countries (Germany €8135.04 vs. €9185.34; Italy €8545.22 vs. €9733.37; Spain €14,859.53 vs. €17,767.19). Uncertainty in efficacy, mean gonadotropin dose and costs did not have a strong effect on the ICERs.

Conclusions: When considering live birth outcomes, treatment with the reference follitropin alfa was more cost effective than treatment with the biosimilar follitropin alfa.  相似文献

Using data about votes emitted by funds in corporate meetings held by US banks from 2003 to 2013, we propose a novel approach based on eigenvalue decomposition to address the issue of communality in voting decisions. Our results indicate that there is a main underlying feature that contributes to explain this voting behaviour. Also, a dimensionality reduction could be accomplished so that a subset of the original data can replicate the sample. These findings confirm that there may be a sort of homogeneous or systematic component when it comes to explain the voting pattern into the banking industry.  相似文献
