Market microstructure effects on volatility at the TAIFEX

This study examines whether changes in the frequency of market clearing or changes in trading hours on competing exchanges that use different auction systems affect the volatility of futures prices. In particular, this study exploits a natural experiment in the frequency of market clearing of stock index futures contracts traded on the Taiwan Futures Exchange (TAIFEX) to assess whether successive increases in the frequency of market clearing are associated with changes in the volatility of futures prices. The impact of changes in the trading hours on the TAIFEX and on the competing Singapore Exchange (SGX) where a similar Taiwanese stock index futures contract trades under a continuous auction market regime is also examined. The evidence for the impact of an increase in the frequency of market clearing on volatility is mixed. However, the introduction of simultaneous opening times for the TAIFEX (which batches orders at the open) and the SGX (which does not) is associated with a significant reduction in the volatility in SGX Taiwanese stock index futures prices. © 2007 Wiley Periodicals, Inc.

Statistical properties of returns: Financial assets versus commercial real estate

This study examines the distribution of commercial real estate returns by region (east, midwest, south, and west), by property type (office, retail, R&D office, and warehouse) and in the aggregate, and compares their distributions to those of financial assets. Nominal and real returns are examined for quarterly, semiannual, and annual periods. The quarterly nominal returns on the financial assets are mostly normal with very little indication of autocorrelation. In contrast, non-normality and autocorrelation are present in most of the nominal quarterly real estate series. The non-normality is greatly reduced when semiannual or annual returns are considered or when the quarterly series are corrected for autocorrelation. The non-normality is also lower for real returns than it is for nominal returns.     

Migration and education subsidies by governments: a game-theoretic analysis

This study is concerned with the implications of the brain drain. "The brain drain alters both the endowments of educated labor and the cost of increasing the endowment of such labor in both countries of immigration and emigration." It thus affects government subsidies for education both directly and indirectly. "This has implications for the burden of education expenditures and net supplies of educated labor in a world with a brain drain. The [author] shows the need for inclusion of a mechanism for transfers between the involved governments if a compensation scheme is to yield Pareto efficient migration."     

A Theoretical Model of the Effects of Public Funding on Saving Decisions by Charitable Nonprofit Service Providers

Why do charitable nonprofit, service‐providing organizations save? What are the tradeoffs between using income to build up cash reserves and serving more clients? Saving may generate income, protect the organization against a drop in donations, and increase the organization's chances of survival. Saving, though, may affect the likelihood that nonprofits receive private and public funding. We model the relationship among private and public income, economic conditions, and nonprofit savings. We find that anticipation of government help during difficult times tends to reduce the amount of saving done by the nonprofit. This effect is strengthened if government officials view unspent donations as indicative of a lack of need. Both these effects provide a strong incentive for nonprofits to spend on current consumption rather than to save for the future, and thus to increase the burden on the public purse.     

Evidence About Auditor–Client Management Negotiation Concerning Client's Financial Reporting

We develop a model of auditor-client accounting negotiation, using the elements of negotiation examined in the behavioral negotiation literature, elaborated to include accounting contextual features indicated in the accounting literature and suggested by interviews with senior practitioners. We use a questionnaire structured according to the model to describe the elements, contextual features and associations between the two groups in a sample of real negotiations chosen by 93 experienced audit partners. The paper demonstrates important aspects of the sampled accounting negotiations and makes suggestions for further empirical and model development research.     

The information content of stock split announcements: Do options matter?

We provide a new test of the informational efficiency of trading in stock options in the context of stock split announcements. These announcements tend to be associated with positive abnormal returns. Our traditional event study results show abnormal returns that are significantly lower for optioned than non-optioned stocks, whether traded on the NYSE, Amex, or Nasdaq. After controlling for market returns, capitalization, book-to-market ratio, and trading volume, we find that the abnormal returns are significantly lower for NYSE/Amex optioned than non-optioned stocks. Although the results for Nasdaq stocks are not as clear, the overall effects tend to be lower after optioning. These findings are consistent with the hypothesis that the prices of optioned stocks embody more information, diminishing the impact of the stock split announcement. They provide new evidence of the beneficial effects of options on their underlying stocks.     

Implementing: Alternatives,costs, and benefits

This essay provides a conceptual framework for thinking about the problem of implementing (i.e. getting things done) as part of the larger process of managing. We shall isolate some alternative approaches to that implementing problem and briefly examine the underlying beliefs, the accompanying technologies, and the attendant costs/benefits of those alternatives. We shall then make a few suggestions about appropriate alternatives for the decade ahead.
