Misuses of Statistics: Lessons for Statisticians, Non-statisticians, Students and Teachers

A bstract . Statisticians, students, teachers and even non statisticians can learn from a study of misuses of statistics. The practitioners can improve their use of statistical methods in research , the student can learn the correct method of analysis and the effects of incorrect analysis, the teacher can improve teaching and the non statistician can learn to evaluate statistical inputs to decision making All users of statistics, professional and nonprofessional, can benefit from the same examples. In this paper, the authors categorize misuses, by both the nature and effect of the misuse, and give examples for each category.     

Interest Rate Risk Rewards in Stock Returns of Financial Corporations: Evidence from Germany

The interest rate sensitivity of stock returns of financial and non-financial corporations is a well-known phenomenon. However, only little is known about the part of total stock returns that is attributable to the compensation an investor receives for being exposed to interest rate risk when investing in equity securities. We pursue here a benchmark portfolio approach, constructing benchmark portfolios having the same interest rate risk exposure as a particular stock. By studying the time series of returns of these asset-specific benchmarks, we find: i) Regardless of the industry considered, the interest rate risk benchmarks of German corporations have mostly earned a significantly positive reward. ii) Returns of interest rate risk benchmarks of financial institutions exceeded significantly those of non-financial corporations. iii) An investor willing to bear nothing but the average interest rate risk of German financial institutions would have earned a mean return of about or even exceeding 70% of the corresponding total stock returns. iv) Returns of the interest rate risk benchmarks of the German insurance sector were significantly higher than those of German banks, which seems to contradict conventional market wisdom that insurances hedge interest rate risks.     

Assigned versus assumed: Towards a contemporary,detailed understanding of subsidiary autonomy

This paper critically documents the rise of autonomy in subsidiary management literature, and develops an agenda for future research in this key area. Integrating and updating the seminal works of Paterson and Brock (2002) and Young and Tavares (2004), the paper begins with a critical review of subsidiary autonomy within the streams of subsidiary management literature. This leads to an assessment of the key contemporary issues requiring further investigation. These issues center around two key types of autonomy: assigned and assumed. We argue these types represent a more accurate, in-depth conceptualization of subsidiary autonomy, and also have significant implications for key related topics, including subsidiary development. This is depicted in an integrative model that draws upon agency theory, the network model of the MNE, the decision process perspective and the bundling model in presenting a revised view of subsidiary autonomy, and offers a basis for further research within the field.

How is Futures Trading Affected by the Move to a Computerized Trading System? Lessons from the LIFFE FTSE 100 Contract

Abstract:  We consider the impact of the May 1999 move to screen trading of the LIFFE FTSE 100 index futures contract. This resulted in a narrowing of the effective spread. Spread determinants are broadly similar in the two regimes. The narrowing of the spread appears due to increased competition among traders and a decline in tick-level volatility rather than to the way these or other variables affect the spread. Market depth appears largely unaffected. Under screen trading, realized spreads widen as more limit orders are taken up rather than in relation to order size per se .     

The information society in California: Social factors influencing its emergence

The authors identify three elements which will influence California's future. First, demographic shifts in the state's population have altered California's ethnic and cultural foundations. Second, the state educational system does not seem prepared to train larger numbers for information work, especially members of its growing ethnic population. Third, almost half the state's workforce is now employed in information-oriented work, whether in the industrial, service, or agricultural sectors. The authors demonstrate that the interaction of these elements has profound implications for California's development.

North-South interdependence: The case of the Federal Republic of Germany

This study examines economic relations between West Germany and the developing countries in the fields of trade, capital flows and migration of labour. Activity in most fields has expanded enormously since the mid-1960s; in addition the traffic has become markedly less one-way. For the purposes of analysis the developing countries are differentiated according to their economic capacity; prospects for co-operation with West Germany appear to differ markedly according to their stage of development. So German development policy, for its part, needs to employ a variety of different strategies. The more highly developed the partner country, the more the field can be left to private initiative, supported by a liberal foreign trade regime.
