Storage changes in biscuits

The purpose of this research was to investigate the changes occurring in biscuits under domestic storage conditions. The experimental work involved the storage of manufactured biscuits under closed, open/light and open/dark conditions for appropriate periods of time. Moisture content, texture, colour and peroxide value were determined throughout the storage time. The results indicate that the moisture content of the samples increased under all storage conditions, with a softening of texture. Peroxide values increase with rapid acceleration towards the end of the storage period. Very little change was observed in the colour of the biscuits.     

The Structure and Incentive Effects of Corporate Tax Liabilities

This paper describes situations in which tax liabilities assume the form of a negative position in a call option. This structure motivates an examination of the investment decisions of taxed corporations in the presence of risk. It is shown that the structure of the tax liability creates an incentive to underinvest in more risky projects and an incentive for conglomerate merger. These effects are then evaluated in the presence of conflicts of interest between stockholders and bondholders, and under alternative assumptions about the tax code, and about the timing of investment and financing decisions.     

Japan's Security Policy in East Asia

Japan's strategic thinking has been driven by three main factors: a fear of isolation, calculation of the geopolitical strength of China (and to a lesser extent, Korea), and accommodation to the prevailing international power structure. During the Cold War Japan aligned with Washington, but maintained sufficient distance to explore a mutually beneficial relationship with China based on Japan's dominant economic position. As Chinese power has grown and Japan's own economic tools for statecraft have slowed, Tokyo has moved closer to the United States to balance Chinese power. Japan has also had to seek new ways to shape the security environment in Asia, turning to multilateral diplomacy such as the Changmai Initiative. Where Japan's diplomacy in Asia in the 1980s and 1990s emphasized Japan's unique ability to champion "Asian" values with the West, increasingly Tokyo has emphasized its unique ability to champion universal values of democracy and rule of law in Asia. This theme has been used by conservative governments to improve Japan's brand over China, but also builds on a tradition of Japanese diplomatic efforts to take a lead in rule-making in the region. Prime Minister Koizumi's assertive foreign policy helped to reinvigorate Japan's international position, but he moved from the traditional three part formulation of Japan's orientation – the U.S. alliance, the UN system and Asia – to a simpler two part formulation of "the U.S.-Japan alliance and international cooperation." The lack of focus on Asia has contributed to growing tensions with South Korea and China over history issues, even as Japan's global and broader regional standing has increased according to most opinion polls. These regional challenges will continue to confront future Prime Ministers well past Koizumi.     

Commentary: Research Productivity Measurement and the Field of Academic Accounting*

The previous issue of Canadian Accounting Perspectives contained three studies that examined various aspects of performance measurement in universities. In this issue, we step back from the acts of performance measurement and disclosure to consider the context within which the demand for increased performance measurement has arisen. The current commentary considers the use of research productivity measures in the field of academic accounting and why the use of these measures is drawing such an equivocal response from academics in the field. Starting from three theoretical perspectives, we consider the use, response, and consequences associated with research productivity measurement.     

When Will Mean-Variance Efficient Portfolios Be Well Diversified?

We characterize the conditions under which efficient portfolios put small weights on individual assets. These conditions bound mean returns with measures of average absolute covariability between assets. The bounds clarify the relationship between linear asset pricing models and well-diversified efficient portfolios. We argue that the extreme weightings in sample efficient portfolios are due to the dominance of a single factor in equity returns. This makes it easy to diversify on subsets to reduce residual risk, while weighting the subsets to reduce factor risk simultaneously. The latter involves taking extreme positions. This behavior seems unlikely to be attributable to sampling error.     

Farewell to the intelligentsia: political transformation and changing forms of leisure consumption in the former communist countries of eastern Europe

This paper refers to evidence from studies of young adults conducted in eight different ex‐communist countries from 1993 onwards, but it is based primarily on data gathered in Ukraine, Georgia and Armenia in 2002. The evidence is used to chart the disintegration of the intelligentsia strata that were consolidated under communism. Members were highly educated and were unified by an intelligentsia lifestyle that included the consumption of state‐subsidized high culture and typically involved interest and participation in public affairs. The evidence that is presented shows that under post‐communism higher education graduates continue to be distinguished by their consumption of high culture. However, their occupations are more diverse in terms of work and market situations. Many, especially those in the more intellectual occupations, have been impoverished, state subsidies for their lifestyles having been withdrawn or reduced, making their lifestyles more expensive. The better‐off are now even more exposed to and involved in the new consumer cultures. This paper explains how the cessation of the intelligentsia’s reproduction as a lifestyle group, and the spread of commercial leisure, will have contributed to the post‐1989/91 decline in political interest and activity among young people in the former communist countries of eastern Europe.     

Price Discovery in Illiquid Markets: Do Financial Asset Prices Rise Faster Than They Fall?

We study price discovery in municipal bonds, an important OTC market. As in markets for consumer goods, prices “rise faster than they fall.” Round‐trip profits to dealers on retail trades increase in rising markets but do not decrease in falling markets. Further, effective half‐spreads increase or decrease more when movements in fundamentals favor dealers. Yield spreads relative to Treasuries also adjust with asymmetric speed in rising and falling markets. Finally, intraday price dispersion is asymmetric in rising and falling markets, as consumer search theory would predict.
