The contribution of Project-based-learning to high-achievers’ acquisition of technological knowledge and skills

The main goals of this study were to look after the technological knowledge construction process by high-school high-achievers, and their ability to design and implement solutions for technological problems. More specifically, we examine the contribution of Project-based-learning (PBL), as pedagogical means for supporting the students’ knowledge acquisition and problem-solving process. The findings show a significant increase in formal knowledge as measured by standardized matriculation exams; an expansion in the scope of technological knowledge acquired and implemented, and in the scope of knowledge resources utilized for the projects; a high level of overall performance as regards to the set of design skills studied; a positive change in attitude towards technology and technological studies; the emergence of consistent design styles by individuals and groups along their work in the projects.     

Dividend policy of German firms: A panel data analysis of partial adjustment models

German firms pay out a lower proportion of their cash flows, but a higher proportion of their published profits than UK and US firms. We estimate partial adjustment models and report two major findings. First, German firms base their dividend decisions on cash flows rather than published earnings as (i) published earnings do not correctly reflect performance because German firms retain parts of their earnings to build up legal reserves, (ii) German accounting is conservative, (iii) published earnings are subject to more smoothing than cash flows. Second, to the opposite of UK and US firms, German firms have more flexible dividend policies as they are willing to cut the dividend when profitability is only temporarily down.     

Disentangling the link between stock and accounting performance in acquisitions

We study the accounting and stock performance of 4547 US acquisitions during 1989 and 2008. We categorise acquisitions into four types based on the four possible combinations of positive or negative abnormal stock performance and abnormal accounting performance. First, we compare the bidder, bid and target characteristics across the four types of acquisitions. We find significant differences. Second, with the help of existing theories we explain these differences in bidder, bid and target characteristics by differences in the acquisition motives.     

Machine Control – A Design and Technology Discipline in Israel's Senior High Schools

This paper presents a concept of the Machine Control discipline developed through the past decade as part of the technological education reform in Israel. The discipline has been widely implemented in senior high schools as an optional matriculation subject. Principles, contents, experience, evaluation and challenges of the curriculum are discussed. Specific features of the discipline in rural, technological and general school environments are presented and illustrated by examples. Arguments in support of a cross-national comparison of specific technology programs are given. This revised version was published online in July 2006 with corrections to the Cover Date.     

Shareholder wealth gains through better corporate governance—The case of European LBO-transactions

We examine shareholder wealth effects in a heterogeneous sample of 115 European leveraged going private transactions from 1997 to 2005. Average abnormal returns as reaction to the LBO announcement amount to 24.20%. In cross-sectional regressions, we find that these value gains can largely be attributed to differences in corporate governance: on a macro level, abnormal returns for pre-LBO shareholders are larger in countries with a poor protection of minority shareholders. On a firm level, companies with a high pre-LBO free float and comparatively weak monitoring by shareholders tend to show high abnormal returns. Furthermore, companies that are undervalued with respect to an industry peer-group exhibit higher announcement returns, indicating that agency conflicts and/or market inefficiencies can serve as an explanation.

Do Corporate Governance Motives Drive Hedge Fund and Private Equity Fund Activities?

We document empirical evidence that both hedge fund (HF) and private equity fund (PE) investments are driven by corporate governance improvements, but address different types of agency conflicts. Whereas HFs focus on firms without a controlling shareholder, in particular family shareholders, PEs invest in firms with low managerial ownership. Both appear to address free cash flow problems differently. Aiming at increasing dividends, HFs tend to use commitment devices that can be implemented over a short horizon. PEs are inclined to longer‐term strategies: they target firms that are particularly well suited for leverage increases because of low expected financial distress costs.     

The Information Content of Dividend Surprises: Evidence from Germany

This paper reconsiders the issue of share price reactions to dividend announcements. We use the difference between the actual dividend and the analyst consensus forecast as obtained from I/B/E/S as a proxy for the surprise in the dividend announcement. Using data from Germany, we find significant share price reactions after dividend announcements. We use panel methods to analyze the determinants of the share price reactions and find evidence in favour of the cash flow signaling hypothesis and dividend clientele effects. We further find that the price reaction to dividend surprises is related to the ownership structure of the firm. The results do not support the free cash flow hypothesis. An additional result of our analysis is that dividend changes are not an appropriate measure to capture the information content of dividend announcements.     

Sooner or Later: An Analysis of the Delays in Insider Trading Reporting

Abstract:  Until October 2004, corporate insiders in Germany were required to report trades in the shares of their firm 'without delay'. Yet in practice, substantial reporting delays were common. We show that the delays are related systematically to the characteristics of the firm. Delays are longer in firms with dispersed ownership and in firms using German accounting standards. This suggests that managers of these firms are less responsive to the informational requirements of the capital market. We further find that abnormal returns after the reporting date of an insider trade are independent of the reporting delay. This implies that prices are distorted in the period between the insider trading and the reporting date. This is a strong point in favour of regulations that require and enforce the immediate disclosure of insider trades.     

Insider Trading and Corporate Governance: The Case of Germany

We analyse transactions by corporate insiders in Germany. We find that insider trades are associated with significant abnormal returns. Insider trades that occur prior to an earnings announcement have a larger impact on prices. This result provides a rationale for the UK regulation that prohibits insiders from trading prior to earnings announcements. Both the ownership structure and the accounting standards used by the firm affect the magnitude of the price reaction. The position of the insider within the firm has no effect, which is inconsistent with the informational hierarchy hypothesis.
