Converging in divergent ways

This paper focuses on intra‐industry trade (IIT) between Central, Eastern and South‐Eastern European (CESEE) countries and the EU‐15. It assesses the determinants of intra‐industry trade by combining a detailed product‐level (HS‐6) trade‐flow database with country‐level structural, monetary and institutional variables. Estimates are obtained with System‐GMM and dynamic fractional response models. Our results suggest that structural factors driving IIT differ in the region, notably perceptions of corruption and the distance in the stock of physical capital from the EU‐15. On the other hand, nominal variables such as the competitiveness of corporate taxation and the flexibility of exchange rate regimes contribute to the increase in intra‐industry trade in the whole region.     

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.     

On the regulation of spatial externalities: coexistence between GM and conventional crops in the EU and the ‘newcomer principle’*

Pollen‐mediated gene flow is one of the main concerns associated with the introduction of genetically modified (GM) crops. Should a premium for non‐GM varieties emerge on the market, ‘contamination’ by GM pollen would generate a revenue loss for growers of non‐GM varieties. This paper analyses the problem of pollen‐mediated gene flow as a particular type of production externality. The model, although simple, provides useful insights into coexistence policies. Following on from this and taking GM herbicide‐tolerant oilseed rape (Brassica napus) as a model crop, a Monte Carlo simulation is used to generate data and then estimate the effect of several important policy variables (including width of buffer zones and spatial aggregation) on the magnitude of the externality associated with pollen‐mediated gene flow.     

Enhancing Arthur Andersen business ethics vignettes: Group discussions using cooperative/collaborative learning techniques

Arthur Anderson & Co. has made a significant contribution to assist and encourage the teaching of business ethics. They provided assistance initially through workshops and curriculum materials; currently they are using campus coordinators to disseminate information and materials. The curriculum materials can be used by the instructor to assist students in practicing their moral reasoning skills and cover four academic areas: Accounting, Finance, Marketing, and Management. These materials include business ethics video vignettes, suggestions on presentation methods, guidelines for implementing a stakeholders' analysis approach to ethical reasoning, and possible discussion questions. The vignettes present ethical dilemmas that persons may encounter in entry level positions. We have used the vignettes, the accompanying discussion questions, and the suggested stakeholder analysis in class presentations. This paper presents a discussion of the basic concepts associated with cooperative learning, an example of the implementation of cooperative learning techniques using the Arthur Andersen Accounting Ethics Vignettes, and empirical results of the influence of these particular group discussions on the students' ethical responses. We did not attempt to measure whether the individuals' moral levels changed, but whether the group discussions stimulated any changes in the students attitudes toward the particular ethical dilemma they viewed.Lucia E.

Does ICT adoption improve access to credit for small enterprises?

Using data at the bank–firm level collected through the 9th UniCredit Survey conducted in 2012 on a large sample of small businesses, we investigate the extent to which a large international bank offers better credit conditions to enterprises that use ICT more extensively. The results, which are robust to selection and endogeneity issues, show that banks tend to grant increasing volumes of credit to such enterprises. We interpret this evidence as the ceteris paribus effect of ICT adoption by small businesses on the quality of information transmitted to banks. Another possible interpretation is that banks consider ICT adoption as a signal of firms’ willingness to innovate. We also discuss implications concerning the key role that technology plays in changing the ‘arm’s length’ versus ‘relationship’ lending paradigms.     

Deregulated Wholesale Electricity Prices in Italy: An Empirical Analysis

In this paper we analyze a time series of daily average prices in the Italian electricity market, which started to operate as a Pool in April 2004. Our objective is to model the high degree of autocorrelation and the multiple seasonalities in electricity prices. We use periodic time series models with GARCH disturbances and leptokurtic distributions and compare their performance with more classical ARMA-GARCH processes. The within-year seasonal variation is modelled using the low-frequency components of physical quantities, which are very regular throughout the sample. Our results reveal that much of the variability in the price series is explained by the interactions between deterministic multiple seasonalities. Periodic AR-GARCH models seem to perform quite well in mimicking the features of the stochastic part of the price process.

The South African disability grant: Influence on HIV treatment outcomes and household well-being in KwaZulu-Natal

This paper explores the implications of the disability grant for household members' well-being and adults' success on ART (antiretroviral therapy). It uses case studies based on data from an in-depth qualitative study of 10 households in KwaZulu-Natal. Receipt of the disability grant ensured that the basic needs of the HIV-infected adult could be met by other household members, especially when the grant was received when the person first met the qualifying criteria and in conjunction with ART. Where treatment was effective, HIV-infected adults were able to make substantial contributions to the well-being of other members in addition to the financial support provided by the grant itself. Thus, early access to financial support in conjunction with commencing ART may lead to improved health outcomes and reduce poverty and vulnerability associated with illness in poor households. This synergistic relationship between social welfare and treatment may in turn contribute to greater cost-efficiency.     

On policymakers’ loss functions and the evaluation of early warning systems: Comment

Sarlin (2013) suggests that if a loss function approach is chosen to derive the optimal threshold for financial crisis early warning indicators, the loss function specification should explicitly take into account the unconditional sample crisis probability. In this comment we argue that this approach is not robust to small perturbations of the preference parameter and is not easy to use for policy purposes. We suggest therefore to continue using a simpler loss function specification.
