Managing Co-occurring Conflicts in Teams

This study extends prior research on conflict in teams by showing that a team’s chances of appropriately managing one type of conflict depends on what other types of conflicts are co-occurring. We interviewed 44 managers from different industries who had recently participated in a negotiating team, asking about within-team conflicts and how those conflicts were managed. The data showed that task conflict increased the likelihood that teams managed co-occurring procedural conflicts appropriately, but that procedural conflicts decreased the likelihood that teams managed co-occurring task conflicts appropriately. These results explain why some teams fail to realize the theorized benefits of task conflict and why procedural conflict does not always have a deleterious impact on team performance: The co-occurrence of these different types of conflict can alter what strategy a team uses to manage conflicts.     

Estimated Macroeconomic Effects of a Chinese Yuan Appreciation

This paper uses a multicountry macroeconometric model to estimate the macroeconomic effects of a Chinese yuan appreciation against the U.S. dollar. The estimated effects on U.S. output and employment are modest. Positive effects on U.S. output are roughly offset by negative effects from a decrease in Chinese output and an increase in U.S. import prices.     

Valuing Seller‐Defaultable Options

This study analyzes seller‐defaultable options that allow option writers to have a free‐will right to default, along with some prespecified default mechanisms. We analytically and numerically examine the pricing, hedging, defaulting, and profitability of the seller‐defaultable options, considering three possible scenarios for seller default. Analyzing the essential implications of seller‐defaultable options, we show that the option price is positively correlated with the default fine, underlying asset price, and volatility. The seller‐defaultable option's Greeks appear more complicated than those of the plain vanilla options. The likelihood of sellers defaulting increases with the underlying asset price, interest rate, volatility, and maturity time. Subject to the default mechanism, the buyers’ trading involves a trade‐off between profits and costs. © 2012 Wiley Periodicals, Inc. Jrl Fut Mark 33:129–157, 2013     

Market volatility and the demand for hedging in stock index futures

This study examines the relation between stock market volatility and the demand for hedging in S&P 500 stock index futures contracts. Open interest is used as a proxy for hedging demand. The analysis employs unique data that identify separately the open interest of large hedgers, large speculators, and smaller traders. Volatility estimates are decomposed into expected and unexpected components, to assess whether traders’ reactions to volatility depend upon its predictability. Results indicate that daily open interest for hedgers increases when unexpected volatility increases. Increases in unexpected volatility may cause hedgers to raise their estimates of future expected volatility, and hence increase their demand for hedging. Open interest of speculators is not related to expected volatility, and is only weakly related to unexpected volatility. The increase in the participation of hedgers in periods of higher volatility is significantly larger than the increase in the participation of speculators. The results suggest that increases in stock market volatility increase the demand for hedging. © 2000 John Wiley & Sons, Inc. Jrl Fut Mark 20: 105–125, 2000     

Towards mentoring the Indian organizational woman: Propositions,considerations, and first steps

The globalized Indian economy creates employment opportunity for educated Indian women and increases gender diversity in Indian Enterprises (IEs). Increased gender diversity presents myriad challenges for integrating women into the managerial ranks of IEs. We highlight these challenges, offer propositions on the Indian culture, the status of women within IEs, and formal mentoring as a human resource development initiative. Further, we use social identity theory as a lens for understanding these challenges, and integrate knowledge from the Western literature on mentoring women. We conclude by suggesting first steps for developing formal mentoring programs aimed at the Indian organizational woman.     

The performance of heteroskedasticity and autocorrelation robust tests: a Monte Carlo study with an application to the three‐factor Fama–French asset‐pricing model

This paper illustrates the pitfalls of the conventional heteroskedasticity and autocorrelation robust (HAR) Wald test and the advantages of new HAR tests developed by Kiefer and Vogelsang in 2005 and by Phillips, Sun and Jin in 2003 and 2006. The illustrations use the 1993 Fama–French three‐factor model. The null that the intercepts are zero is tested for 5‐year, 10‐year and longer sub‐periods. The conventional HAR test with asymptotic P‐values rejects the null for most 5‐year and 10‐year sub‐periods. By contrast, the null is not rejected by the new HAR tests. This conflict is explained by showing that inferences based on the conventional HAR test are misleading for the sample sizes used in this application. Copyright © 2007 John Wiley & Sons, Ltd.     

Redefining the Human Development Index to Account for Sustainability

Earlier measures of growth like Gross Domestic Product per capita, or even more recent measures like the Human Development Index (HDI), failed to consider the ‘environmental’ aspect of development. Currently, countries that have accepted the sustainability challenge are finding ways to determine if they are making progress in a sustainable way by addressing the environmental aspect of development. This paper attempts to improve the HDI by adding an ‘ecological footprint to total bio-capacity ratio’ as an indicator of environmental resource use. This new index, the Environmentally Stressed Human Development Index (ESHDI) while trying to account for sustainable development, dramatically alters the original HDI rankings of countries. Some ‘high’ and ‘medium’ income countries are enduring excessive environmental stress to sustain economic development.     

Alternatives to Paying Child Benefit to the Rich: Means-Testing or Higher Tax?

There appears to be a general movement away from universal child benefits and towards means-testing. In the present article we argue that instead of suppressing the labour supply of middle-income parents by withdrawing the transfer as a function of income, one should consider the alternative of financing a generous universal child benefit by increasing taxation of income. The implications of means-testing compared with a tax-financed universal alternative are discussed analytically in a piecewise linear schedule and by combining information from behavioural and non-behavioural micro-simulation models. Our results provide support for making child benefit universal instead of means-tested.
