Prämienkalkulation und die „Sanierung“ von Versicherungsverträgen

For assessing the risk adjusted insurance premiums, we always face the challenge that we don’t know the respective distribution functions of the probable claims and the probability of occurrence. Purely chance-based deviations from expected damages are no sufficient reason for premium increases. This means that for preparing for such deviations we have to distinct between chance-based and other deviations from expected and realised damage events. For adjusting insurance contracts due to new information, there are three possible strategies: first, we could ignore the past premium and calculate them based on the new data sample. Alternatively we could make use of a Bayesian learning process, which means to adjust the past premiums by taking into account the new information. The third strategy refers to a statistical test of hypotheses. This means to only adjust a premium if the original assumptions on the possible distribution of claims have to be rejected statistically. Looking at the certainty of the contracts and a steady calculation basis, there are many reasons in favour of the statistical test of hypotheses. The stringent usage of this method can lead to a sound basis for negotiations between insurance provider and holder. The improvement of transparency of taken risks is regulatorily desirable as well as helpful for evaluation of solvency.     

Incorporating Both Positive and Negative Association Rules into the Analysis of Outbound Tourism in Hong Kong

This article presents a novel approach to data mining that incorporates both positive and negative association rules into the analysis of outbound travelers. Using datasets collected from three large-scale domestic tourism surveys on Hong Kong residents' outbound pleasure travel, different sets of targeted rules were generated to provide promising information that will allow practitioners and policy makers to better understand the important relationship between condition attributes and target attributes. This article will be of interest to readers who want to understand methods for integrating the latest data mining techniques into tourism research. It will also be of use to marketing managers in destinations to better formulate strategies for receiving outbound travelers from Hong Kong, and possibly elsewhere.     

Sub-national institutions,firm strategies,and firm performance: A multilevel study of private manufacturing firms in Vietnam

Some private small and medium sized enterprises (SMEs) in transition economies have actively internationalized. This decision needs to accommodate institutional conditions that vary, not only between countries, but also within an individual country. Our paper examines the relationship between export strategy and firm performance, and the extent that sub-national institutional factors moderate this relationship. Using multilevel data analysis techniques with a sample of private manufacturing firms in Vietnam, we find institutional factors moderate export strategy and firm performance's relationship.     

The value impact of name changes evidence from Chinese firms during the technology boom

For a sample of US stocks in the period 1998–1999, Cooper, Dimitrov, and Rau (2001) report dramatic value increases in the 10 days around the announcement of dotcom name changes. We find much smaller value changes for a sample of Chinese listed firms with changes to internet-related dotcom names for the 1998 to 2002 period. This result is surprising given the high proportion of retail trading in China and the prohibition to short sell Chinese stocks. Also in contrast to Cooper, Dimitrov, and Rau (2001), we find that most of the value increase for our sample firms is realized gradually prior to the announcement. Further investigation reveals that our sample firms experience more frequent CEO-turnover, significant increase in return-on-assets, and involve more restructure activities around the name change event. These results suggest that the value increases for firms with name changes are the consequence of substantial and successful operational changes, and that the name change is simply part of that process, instead of the cosmetic effects of name change or investor mania suggested by previous studies.     

Interorganizational Favour Exchange and the Relationship Between Doing Well and Doing Good

This article examines whether ethical business practice enhances financial performance with respect to interorganizational favour exchange. We argue that the link between the ethicality and economic utility of interorganizational favour exchange is governed by: (1) organizational–individual interest alignment/conflict and (2) the fairness or justifiability of favour exchanges from the perspective of third parties. We classify interorganizational (IO) favour exchange into four types (Business–Personal, Personal–Business, Personal–Personal and Business–Business favour exchange). Our analysis shows that the first three types of favour exchange are unethical as they involve conflicts between organizational and individual interests in one or both participating organizations that negatively affect organizational value creation. The last type of favour exchange involves organizational–individual interest alignment in both participating organizations and positively affects the capacity of those involved in the exchange to create value. Favour exchanges of this fourth variety are ethically justifiable unless they unfairly damage the legitimate interests of third parties. In the latter case, these favour exchanges create the risk of negative third party reactions, which in turn affect the sustainability of the benefits of the favour exchanges to the focal group (the dyad). Our research results advance understanding of the ethical and economic implications of IO favour exchange, counter the prejudice against this behaviour in organizations, provide ethical guidance for management and business practice, and have implications for the relationship between doing well and doing good.     

Trade Liberalisation and Poverty Reduction in Vietnam

This paper investigates the impacts of trade liberalisation on poverty reduction in Vietnam during the period of economic reform. Using a combined approach dealing with four transmitting channels from trade to poverty, the major findings are summarised as follows. First, Vietnam's trade liberalisation has fostered economic growth, which has helped to raise per capita GDP and reduce poverty. Second, trade liberalisation has directly benefited the poor through creating pro‐poor employment and raising wages. Third, another impact of trade liberalisation on poverty is income and substitution effects associated with reduced domestic prices of importables and increased domestic prices of exportables such as coffee and rice. Fourth, trade liberalisation has indirectly benefited the poor because it raises government revenue, which enhances the government's ability to subsidise the poor. Finally, although the poverty rate in Vietnam has been reduced impressively, there is an increasing disparity between urban and rural areas and, among the latter, concern does exist regarding ethnic minorities.     

Foreign direct investment and exports The experiences of Vietnam1

We examined the implementation statuses of a total of 5,919 foreign direct investment (FDI) projects approved by the Vietnamese Ministry of Planning and Investment since 1988, and compiled a database of actually disbursed FDI in Vietnam. The database covers FDI flows into Vietnam from 23 countries from 1990 to 2004. Using the data, we analyzed the impact of FDI on the exports of Vietnam with gravity equations. The empirical results demonstrate that FDI is one of the major factors driving the rapid export growth of Vietnam. It has significantly facilitated the expansion of Vietnam's exports to FDI source countries. In particular, the empirical analysis shows that a 1 percent increase in FDI inflows will be expected to give rise to a 0.13 percent increase in Vietnam's exports to these countries.     

An inquiry into the transformation process of village-based industrial clusters: The case of an iron and steel cluster in northern Vietnam

While village industries are known to play an important role in the development of rural areas in developing countries, little is known about village industries in transition economies. This paper inquires into the transformation process of a village industry in northern Vietnam from a traditional to a modern cluster where new iron and steel products are produced. We found that proprietors’ human capital acquired by formal education and experience in marketing and management as well as their family ties are critically important for upgrading product lines and improving management, marketing, and consequently the overall performance of the village enterprises.     

The impact of work and non‐work migration on household welfare,poverty and inequality

This article estimates the impact of work migration and non‐work migration on per capita income, per capita expenditures, poverty and inequality in Vietnam using data from the two most recent Vietnam Household and Living Standard Surveys. We find that both work migration and non‐work migration have a positive impact on per capita expenditures of migrant‐sending households. Non‐work migration significantly decreases the incidence, depth and severity of national poverty. The effect of work migration on poverty is much smaller. Still, while work migration does not lift people out of poverty, it makes their poverty less severe. In addition, both work migration and non‐work migration decrease inequality, albeit only very slightly.     

Domestic liquidity and cross-listing in the United States

This study examines changes in domestic liquidity after cross-listing in the United States. Our liquidity measures are based on intraday data from domestic markets for a large sample of firms that cross-list in the United States and for a matched sample of firms that do not cross-list. We find that unadjusted liquidity significantly improves after cross-listing. However, after controlling for contemporaneous changes in liquidity for a matched sample of firms that do not cross-list, there is no evidence of improvements in domestic liquidity due to cross-listing. Our results offer no support for the bonding hypothesis, or for the hypothesis that cross-listing improves domestic liquidity because of increased intermarket competition and additional order flow.
