Korean unification prospects: an assessment through the BDN-model

The debate on the possible unification of South Korea and North Korea has often been assessed from the economic perspective, which is insufficient since unification entails not only the integration of two economies but political, social and technological integration of two territories. Using the box negotiation diagram model, this paper expands the scope of the study on South Korea and North Korea unification through a multidisciplinary approach encompassing the political, economic, social and technological perspectives. Given the huge imbalanced points of unification drawn from our analysis, we observed more divergence than convergence hence, hinging the possibility of unification of serious negotiation.     

Bootstrapping Financial Time Series

It is well known that time series of returns are characterized by volatility clustering and excess kurtosis. Therefore, when modelling the dynamic behavior of returns, inference and prediction methods, based on independent and/or Gaussian observations may be inadequate. As bootstrap methods are not, in general, based on any particular assumption on the distribution of the data, they are well suited for the analysis of returns. This paper reviews the application of bootstrap procedures for inference and prediction of financial time series. In relation to inference, bootstrap techniques have been applied to obtain the sample distribution of statistics for testing, for example, autoregressive dynamics in the conditional mean and variance, unit roots in the mean, fractional integration in volatility and the predictive ability of technical trading rules. On the other hand, bootstrap procedures have been used to estimate the distribution of returns which is of interest, for example, for Value at Risk (VaR) models or for prediction purposes. Although the application of bootstrap techniques to the empirical analysis of financial time series is very broad, there are few analytical results on the statistical properties of these techniques when applied to heteroscedastic time series. Furthermore, there are quite a few papers where the bootstrap procedures used are not adequate.     

A non-parametric independence test using permutation entropy

In the present paper we construct a new, simple, consistent and powerful test for independence by using symbolic dynamics and permutation entropy as a measure of serial dependence. We also give a standard asymptotic distribution of an affine transformation of the permutation entropy under the null hypothesis of independence. The test statistic and its standard limit distribution are invariant to any monotonic transformation. The test applies to time series with discrete or continuous distributions. Eventhough the test is based on entropy measures, it avoids smoothed non-parametric estimation. An application to several daily financial time series illustrates our approach.     

The economic consequences of corporate tax rates reductions in the EU: Evidence using a computable general equilibrium model

In a globalised world, governments are eager to attract foreign investors by lowering corporate tax rates. Recent trends point towards a revival of a race to the bottom in corporate income tax (CIT) rates in developed economies. EU countries have been active in this respect. A generalised fall in CIT rate could prove detrimental to tax revenues and trigger increase in other taxes to meet fiscal policy objectives. However, it could also spur investment and growth and prove to be a good fiscal policy strategy if, as a result, the corporate tax base increases. The final economic and fiscal impact of a reduction in CIT rates is therefore unclear. Using a CGE model, we find that uncoordinated tax reforms significantly impact national economies and third‐country effects can be significant when large countries implement CIT rate cuts. Small countries are better off unilaterally reducing their CIT rate at the expense of other EU countries. We find that negative spillovers are mitigated when the country reducing its CIT rate restores its budget balance by cutting either public expenditures or social transfers. A larger degree of non‐EU capital mobility also tends to reduce the negative spillover effects of unilateral CIT rate reductions.     

Technology transfer in Mexico: Past patterns and new problems related to the North American free trade agreement

As the Mexican economy prepares to transition from a relatively closed and protected market to a regionally integrated free market which is part of the proposed North American Free Trade Agreement (NAFTA), a change in its technology licensing environment will be needed to enable Mexican companies to compete for technology with firms from the other member countries of the NAFTA. This study identifies the national sources which have provided Mexico with technology and the Mexican industrial sectors which have been able to attract this technology in the 1980s. It further evaluates the current licensing environments in Canada, Mexico, and the U.S.A. as well as in the Latin American Integration Association (LAIA). The study provides recommendations for changes to the Mexican licensing environment and proposes strategies for attracting technology to Mexican industry under the changed conditions which would be introduced by the NAFTA. © 1993 John Wiley & Sons, Inc.     

Organic as a Heuristic Cue: What Spanish Consumers Mean by Organic Foods

One of the strategies employed by companies to differentiate themselves from others, in the food market, has been to market organic products according to the assumption that environmental values are an important influence on people's behavior. However, studies of the behavior of organic food consumers show that there is some debate on this subject. Although some studies associate organic food consumption with motives and attitudes in which the environment plays a predominant role, a greater number conclude that the motives for consuming this type of food are basically egoistic (related to health, food safety, or the quality or flavor of the food). This can lead to problems in deciding the central thrust of the marketing strategy. The purpose of this paper is to analyze the meaning and interpretations placed on the term “organic,” and how they are integrated, as a way to explain consumption behavior. Qualitative research methods were adopted for this purpose. Four focus group sessions with different sociodemographic profiles, held in the cities of Madrid and Seville, in Spain, displayed two evident paradoxes, which could indicate that environmental motives are not important for consumers in this market. It is concluded that the term “organic” plays an important role as a heuristic cue to superiority, irrespective of the consumer's knowledge about the real features of organic food. Three alternative models are presented to explain consumer behavior. These results could be useful to food companies, largely in connection with positioning this type of product and with their communications policy.     

Toward an understanding of online information processing in e-tourism: does national culture matter?

Tourism is undoubtedly among the industries that better reflect the effects of globalization, technological advances (i.e. the Internet) being one of the most relevant drivers. Given the current market saturation of this sector, a better understanding of how tourists from different cultures process online information and forge their attitudes and behavioral intentions is called for. Nevertheless, national culture may have a major influence on the effectiveness of online tourist marketing activities. This study contributes to the extant body of knowledge via the analysis of the influence of perceived risk on how tourists process the information while browsing a tourist destination website, form their attitudes and behavioral intentions toward the destination. The effect of national culture on such antecedents is examined via a cross-cultural research to compare Spanish and British cultures. A theoretical model is proposed to integrate the effect of perceived risk and variables regarding technology acceptance on tourist responses.     

Integrated reporting: an international overview

This article analyses the determinants associated with the use of the Integrated Report (IR) as a corporate reporting model for sustainability information. IRs provide information regarding the use and interdependence of different company resources. The previous literature has identified determinants behind the presentation of IRs at the country level (legal system, investor protection, economic development, cultural characteristics) as well as at the company level (size, industry, verification of the sustainability report). Our work contributes to the literature by using a novel statistical approach that addresses the likelihood of the non‐independence of data: companies in the same country are more similar to one another than are companies from different countries. Our results confirm significant inter‐country variance, which may be partially explained by the existence of specific regulations and the individualism vs. collectivism dimension. Although we confirm the effect of company‐level determinants, our results do not support the role of specific variables tested as determinants.     

Another trip to the mall: a segmentation study of customers based on their activities

In this exploratory study, a segmentation analysis of a shopping mall's customers is conducted according to the activities they performed during their visit, based on a methodology developed by Bloch et al. (J. Retailing 70 (1994) 23). This methodology is extended with measures of perceptions, emotions, and motivations. Activity-based clusters, obtained with the Variable Neighborhood Search metaheuristic applied to the P-median problem. (Hansen and Mladenovi , 1997) proved to be significantly different along many psychographic dimensions (including atmospheric perceptions), and demographic variables. This profiling methodology successfully synthesizes many segmentation approaches that were used separately in previous studies. This results in a complete and distinct profile of each group that may be a useful tool for retail strategists.
