Gap in relative importance of service activities closed

Conclusion Overall it is evident that the relative importance of services and service activity trends in the USA and west Germany is very similar. In other words the activity structure in Germany is indeed “modern”. Also in highly productive areas of production, value adding largely takes the form of service activities. Thus the employment problem in Germany results not from outdated activity structures; the causes are rather those macroeconomic reasons to which the DIW has repeatedly drawn attention⁷. German economic policy must ensure that the framework of macroeconomic conditions is changed to allow jobs to be created. Whether these jobs are created in certain branches or activities is of secondary importance. Having said this, in Germany, too, it is to be expected that more than two out of every three new jobs created will be service jobs. Even so, a quarter of new jobs will be created in industry.     

Symposium on Infant Industries: A Comment

This paper uses the fiscal response framework to investigate the extent to which different categories of foreign aid flows, namely project aid, programme aid, technical assistance and food aid, displace public savings and affect the recipient country's dependence on aid, using time series data for Côte d'Ivoire for the period 1975–99.The results indicate that, in general, project aid flows tend to reduce public savings and worsen Côte d'Ivoire's dependence on aid more than the other categories of aid flows. This finding therefore suggests that accounting for aid heterogeneity in aid studies as well as aid policies design and implementation could be crucial in improving aid effectiveness to achieve the Millennium Development Goals.     

Are intraday reversal and momentum trading strategies feasible? An analysis for German blue chip stocks

The success of trading strategies that lead to abnormal excess returns based on annual/monthly investment periods has recently declined significantly. We adopt the original frameworks of De Bondt and Thaler (J Finance 40(3):793–808, 1985) and Jegadeesh and Titman (J Finance 48(1):65–91, 1993) to an intraday reversal as well as momentum strategy scheme based on 5-min stock returns. We analyze 16 reversal and momentum strategies each with ranking and holding periods of 60, 120, 180 or 300 min (reversal strategies) and 15, 30, 45 or 60 min (momentum strategies) from a retail investor’s perspective. We find no indications for momentum in stock prices but strong indications for reversals. Our results are furtherly robust regarding to market adjustment, portfolio sizes and skipping periods between ranking and holding periods. Our results show that the returns of the reversal strategies are statistically significant, however, yet too small to be economically significant. Our results also confirm the efficiency on the stock markets.

     

The Client as a Source of Institutional Conformity for Commitments to Core Values in the Auditing Profession*

Based on an analysis of questionnaire data from a large sample of certified auditors, we examine how the main type of client being served influences auditor conformity to the core values of their profession. We contrast auditors of (primarily) listed companies with auditors of (primarily) single member companies, that is, limited liability companies with a single owner who typically is also the only employee of the company. We show that these two groups of auditors differ in the extent to which they hold certain values important (i.e., show compliance) and in the closeness with which these values are held within each group of auditors (i.e., show convergence). Our results also demonstrate that the type of client predominantly served by an auditor is relevant for explaining variation in professional values both within and between organizational contexts. In addition, we offer a new theoretical approach to classifying auditors and analyzing their commitment to core values of the profession. We analyze commitment to values via both compliance and convergence, two often overlooked aspects of conformity to value commitments in professions.
