The Carcinoembryonic Antigen Gene Family

The molecular cloning of carcinoembryonic antigen (CEA) and several cross-reacting antigens reveals a basic domain structure for the whole family, which shows structural similarities to the immunoglobulin superfamily. The CEA family consists of approximately 10 genes which are localized in two clusters on chromosome 19. So far, mRNA species for five of these genes have been identified which show tissue variability in their transcriptional activity. Expression of some of these genes in heterologous systems has been achieved, allowing the localization of some epitopes. The characterization of a CEA gene family in the rat and a comparison with its human counterpart has been utilized in the development of an evolutionary model

Job shopping after vocational training? An empirical analysis of the transition from apprenticeship training to work

This econometric study deals with the question as to what extent apprentices after successfully completing their training stay with the firm where they have received their training and, if so, how long that job tenure holds. Determinants of both decisions can be seen from both the employer`s and the employee`s viewpoint. The firm is interested to employ this apprentices in order to collect the returns from its investment in their training which frequently is associated with net costs. On the other hand, the firm dismisses apprentices if training is viewed by the firm as a screening device or if apprentices are engaged in work for which, in terms of wages, they are too expensive afterwards. The young trained worker bases his or her decision to stay or to leave on considerations such as experimenting with several jobs ("job shopping"). The realization of such an experimenting may depend on the situation on the labour market. The empirical part uses individual employee data covering the time period 1980 to 1991 in West Germany and is based on a hazard rate model. --Training,Apprenticeship,Youth Unemployment,Matching

There's no Place Like Home: A Strategic Framework to Overcome Liability of Foreignness in the German Car Market

Globalization has led to exciting new business opportunities around the globe. Still, national and cultural boundaries have not evaporated into a "borderless world". Several studies have identified so-called liabilities of foreignness that arise from a lack of embeddedness and roots in the host market and subsequent competitive disadvantages. Countervailing strategies for these effects have remained scarce so far. We suggest that this is due to the lack of a viable approach to identify and quantify these effects and develop a conceptual framework to empirically estimate the individual degree of liability of foreignness of a firm from a market perspective. We suggest that disruptive changes in a society change the dynamics of liability of foreignness and generate opportunities for foreign companies to optimize their localization strategies. We apply our approach to a large mature market with established international competition : the German new car market. For a comprehensive sample of roughly 1,400 car models from 2003 we estimate the relative turnover disadvantage for all major foreign manufacturers. We find that most foreign producers have managed to overcome liabilities of foreignness in Germany through firm-specific advantages. Still, some face significant challenges. A submarket analysis shows that home market advantages are more deeply rooted in the Western part of Germany and that foreign competitors find a more accessible competitive environment in Eastern Germany. Therefore, East Germany is a superior platform for deploying effective and efficient countervailing strategies. Moreover, we identify a broader rationale to engage early and decisively in untapped but promising markets like China. --Liability of foreignness,automotive market,multinational strategy,seemingly unrelated regressions

Corporate governance and expected stock returns: evidence from Germany

Recent empirical work shows that a better legal environment leads to lower expected rates of return in an international cross-section of countries. This paper investigates whether differences in firm-specific corporate governance also help to explain expected returns in a cross-section of firms within a single jurisdiction. Constructing a corporate governance rating (CGR) for German firms, we document a positive relationship between the CGR and firm value. In addition, there is strong evidence that expected returns are negatively correlated with the CGR, if dividend yields and price-earnings ratios are used as proxies for the cost of capital. Most results are robust for endogeneity, with causation running from corporate governance practices to firm fundamentals. Finally, an investment strategy that bought high-CGR firms and shorted low-CGR firms would have earned abnormal returns of around 12 percent on an annual basis during the sample period. We rationalize the empirical evidence with lower agency costs and/or the removal of certain governance malfunctions for the high-CGR firms
