Competition,comparison, and innovation

Competitive firms can make a comparison with each other and easily figure out the better strategy, while monopoly firms cannot. Therefore, a competitive firm may be more likely to try low cost innovations than a monopoly firm may.     

The Effectiveness of Single‐Sex Schools through Out‐of‐School Activities: Evidence from South Korea

Students’ out‐of‐school activities and time use can play a crucial role in facilitating the effect of schools on students’ achievement. Using data from Seoul, South Korea, where students are randomly assigned into schools, we show that when single‐sex schools improve students’ test performance, their effect is positive on students’ time spent on study‐related out‐of‐school activities. Our results indicate that out‐of‐school activities explain roughly 21%–30% of the effect of single‐sex schooling on test performance.     

Services cultural alignment in offshoring: The impact of cultural dimensions on offshoring location choices

Empirical research on the growing wave of services offshoring has examined the impact of several key factors such as wages and personnel quality on firm choices of offshore locations. However, examinations of culture in services offshoring to date have largely been confined to the relatively coarse concept of aggregate cultural differences between the home and host countries. We propose that specific cultural attributes are more closely aligned with successful service provision. We empirically examine our theoretical development of service cultural alignment and investigate the impact of cultural dimensions on the location of service offshoring projects. In addition, we examine whether Western and Asian firms have different cultural preferences in terms of the location of services offshoring projects. We find that host countries with lower levels of Hofstede's uncertainty avoidance as well as higher levels of individualism and power distance are able to attract greater numbers of service offshoring projects, even after controlling for macroeconomic, linguistic, and risk-related factors. We did not find that Western and Asian firms have different cultural preferences in this regard. We discuss implications of the findings with respect to theory, managerial practice, and governmental policy.     

Traders' strategic behavior in an index options market

We analyze traders' strategic behavior in an index options market, examining the relationships among expected duration, frequency of trades, trade size, and time to maturity using a modified ACD model. Using intraday data at‐the‐money put and call options, we obtain the following results: (1) Frequency of trades contains more information about future option price volatility than does trade size. This may result from institutional or large traders who have issued naked options using the delta‐neutral strategy to hedge those options. This also suggests that informed traders use their informational advantage little by little, rather than all at once. (2) Option volatility increases as the maturity date approaches, contradicting the prediction of the Black‐Scholes model. (3) The duration of the previous interval has a persistent effect on expected duration of the current interval. (4) For the estimation of the modified ACD model, the standardized distribution of duration is Weibull with γ < 1, not exponential. (5) The duration in the options market exhibits an inverse U‐shaped diurnal pattern, much like that of the U.S. stock market. However, unlike in the U.S. stock market, the index options duration becomes much shorter right before lunch hour (12:00 pm). © 2005 Wiley Periodicals, Inc. Jrl Fut Mark 25:105–133, 2005     

Capital market equilibrium without riskless assets: heterogeneous expectations

The existence theorem of Allingham (Econometrica 59:1169–1174, 1991) for the capital asset pricing model (CAPM) is generalized to the case where agents have heterogeneous expectations on the return distribution and the mean-variance utility functions are quasiconcave. This result is built upon new conditions which are distinct from and weaker than the conditions imposed on the CAPM in the literature.      

Accounting research: An analysis of theories explored in doctoral dissertations and their applicability to Systems Theory

This study examined theories used in accounting doctoral dissertations and found that dissertations in this discipline test theories drawn from economics, finance, psychology, and sociology, with 53% from economics and finance and 27% from psychology. Further, a primary conclusion of this paper is that doctoral research in accounting explores subsets of organizational activity consistent with the premises of Systems Theory.     

Towards a Comprehensive Framework for Environmental Management Accounting — Links Between Business Actors and Environmental Management Accounting Tools

This article develops a comprehensive framework for environmental management accounting (EMA) linking business actors and EMA tools. The proposed framework provides structure for managers to understand and assess the variety of environmental management accounting tools that have been developed to date, with the intention of encouraging their adoption. The framework systematically integrates two major components of environmental management accounting — monetary environmental management accounting (MEMA) and physical environmental management accounting (PEMA). It highlights the past/future and short/long-term time dimensions of the different tools, and the regularity of information generation, before concluding with a brief discussion about choice of the most important EMA tools.     

The global threat of deflation calls for swift interest rate cuts in Europe

Conclusions Given the serious crisis in Asia and evidence of its spreading to other developing and transition countries, the attempt by German economic policymakers to achieve faster economic growth and higher employment almost exclusively by means of successes on export markets appears likely to fail sooner than had been expected by the DIW⁵. The significance of domestic demand has been systematically underestimated in recent years. With the help of extremely low pay settlements, the D-Mark was devalued in real terms; this promoted exports, but at the same time led to growth losses in private consumption and investment that more than offset the gains in exports. On top of this German fiscal policy—as documented in the following report in this issue—has weakened domestic demand and investment activity. This strategy might have worked if a symmetrically oriented monetary policy had reacted to the deflationary trend inherent in pay settlements and the fiscal-policy stance by swiftly and significantly reducing interest rates. This did not happen. It was therefore inevitable that the crisis in sales markets made its full effects felt on economic growth. More seriously still, if cost deflation in Germany is not brought to an end in the coming year by a return to productivity-oriented wage settlements, it will pose a major threat to the European Monetary Union.⁶ If Germany pursues a beggar-thyneighbour policy in a Europe without exchange rates, this can only result in deflation and a downward economic spiral.⁷     

The benefits and costs of ethanol: an evaluation of the government’s analysis

Ethanol production in the United States has been steadily growing and is expected to continue growing. Many politicians see increased ethanol use as a way to promote environmental goals, such as reducing greenhouse gas emissions, and energy security goals. This paper provides a benefit-cost analysis of increasing ethanol use based on an analysis by the Environmental Protection Agency. We find that the cost of increasing ethanol production to almost ten billion gallons a year is likely to exceed the benefits by about three billion dollars annually. We also suggest that earlier attempts aimed at promoting ethanol would have likely failed a benefit-cost test, and that Congress should consider repealing ethanol incentive programs, such as the ethanol tariff and tax credit.
