Non-coercive influence: Scale development and validation based on resource and relational paradigms

To overcome competition in an increasingly network dependent market, retailers are required to influence upstream channel partners while sustaining relationships. However, the contemporary supply chain literature has not sufficiently leveraged the resource and relational paradigms to examine influence. Grounded on resource dependency theory and commitment-trust theory paradigms, this study describes conceptualization and operationalization of a 12-item scale for measuring non-coercive influence on upstream channel partners in retail supply chain management (R-SCM) context. The study is based on responses from 547 retail professionals in India obtained over four successive surveys. Psychometric properties were assessed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The proposed scale demonstrates construct validity. Invariance-testing carried out over 4-levels of increasingly demanding equivalence confirmed cross-validation. Nomological validity of the scale was tested by evaluating association with suppliers’ intention to cooperate. The results indicate existence of three dimensions of non-coercive influence: collaborative intent, market intelligence dissemination, and operational support. Retailers can use the scale to assess their personnel's non-coercive influence behavior over suppliers.     

Testing for PPP: Should we use panel methods?

A common finding in the empirical literature on the validity of purchasing power parity (PPP) is that it holds when tested for in panel data, but not in univariate (i.e. country-specific) analysis. The usual explanation for this mismatch is that panel tests for unit roots are more powerful than their univariate counterparts. In this paper we suggest an alternative explanation. Existing panel methods assume that cross-unit cointegrating relationships, that would tie the units of the panel together, are not present. Using simulations, we show that if this important underlying assumption of panel unit root tests is violated, the empirical size of the tests is substantially higher than the nominal level, and the null hypothesis of a unit root is rejected too often even when it is true. More generally, this finding warns against the automatic use of panel methods for testing for unit roots in macroeconomic time series.First version received: November 2001/Final version received : October 2003     

Trading in derivatives when the underlying is scarce

Regulatory restrictions and market frictions can constrain the aggregate quantity of long and short positions in a security. When these constraints bind, we refer to the security as scarce, and its price becomes distorted relative to its value in a frictionless market. We show that an otherwise redundant derivative can reduce the price distortion of the underlying security by relaxing its scarcity. We also show that it is especially important to analyze the underlying and derivative markets jointly when evaluating the impact of regulation, such as short-sales bans and position limits in derivatives, that restricts trade.     

Softlifting: A model of motivating factors

Softlifting (software piracy by individuals) is an unethical behavior that pervades today's computer dependent society. Since a better understanding of underlying considerations of the behavior may provide a basis for remedy, a model of potential determinants of softlifting behavior is developed and tested. The analysis provides some support for the hypothesized model, specifically situational variables, such as delayed acquisition times, and personal gain variables, such as the challenge of copying, affect softlifting behavior. Most importantly, the analysis indicated that ethical perception of softlifting has no significant affect on softlifting behavior. These findings suggest major implications for both software manufacturers and academicians attempting to reduce piracy behavior through ethics instruction.Penny Simpson is an assistant professor of marketing at Northwestern State University in Natchitoches, Louisiana.

Order Flows,Investor Sentiments and Feedback Trade in Index Futures Market

This paper examines the presence of feedback trading, and investor sentiment drove feedback trading by traders in the Nifty 50 index futures contract in India. The results of the study using high-frequency data sampled at 10 min interval using VAR and contemporaneous VAR model as applied to market microstructure settings reveals negative evidence of feedback trade and investor sentiment-driven feedback trade in Nifty 50 futures contract. Further, consistency with noise trading hypothesis, order flows in Nifty 50 futures contract is less informative when traders are overly optimistic.

     

Financing the sustainable management of Rwanda's protected areas

Rwanda's Nyungwe National Park is a biodiversity hotspot with the most endemic species in the ecoregion and the highest number of threatened species internationally. Nyungwe supplies critical ecosystem services to the Rwandan population including water provisioning and tourism services. Tourism in the Park has strong potential for financing enhanced visitor experiences and the sustainable management of the Park. This paper explores quantitatively the economic impacts of adjustment in Park visitation fees and tourism demand as a source of revenues to improve Park tourism opportunities and ongoing operations and maintenance. The methods developed in this paper are novel in integrating the results of stated preference techniques with a regional computable general equilibrium modelling approach to capture multisectoral, direct, indirect and induced impacts. Such methods have strong potential for assessing revenue generation alternatives in other contexts where park managers are faced with the need to generate additional revenue for sustainable park management while facing diminishing budget allocations. Results of this analysis demonstrate that adjustment of Park fees has a relatively small impact on the regional economy and well-being when compared with a strategy aimed at generating increased tourism demand through investment in improving the visitor experience at Nyungwe National Park.     

System of crop intensification for more productive,resource-conserving,climate-resilient,and sustainable agriculture: experience with diverse crops in varying agroecologies

With continually increasing demand for food accompanied by the constraints of climate change and the availability and quality of soil and water, the world’s farmers are challenged to produce more food per hectare with less water, and with fewer agrochemical inputs if possible. The ideas and methods of the system of rice intensification which is improving irrigated rice production are now being extended/adapted to many other crops: wheat, maize, finger millet, sugarcane, tef, mustard, legumes, vegetables, and even spices. Promoting better root growth and enhancing the soil’s fertility with organic materials are being found effective means for raising the yields of many crop plants with less water, less fertilizer, reduced seeds, fewer agrochemicals, and greater climate resilience. In this article, we review what is becoming known about various farmer-centred innovations for agroecological crop management that can contribute to agricultural sustainability. These changes represent the emerging system of crop intensification, which is being increasingly applied in Asian, African, and Latin American countries. More research will be needed to verify the efficacy and impact of these innovations and to clarify their conditions and limits. But as no negative effects for human or environmental health have been identified, making these agronomic options more widely known should prompt more investigation and, to the extent justified by results, utilization of these methodologies.     

The scope and trajectory of strategic HR research: evidence from American and British journals

Many have argued that the field of human resource (HR) management has successfully transformed itself from the functional orientation of personnel management to a strategic orientation that is more relevant to the goals and effectiveness of business in the current competitive landscape. In this article, we assess that proposition by reviewing almost 1000 award-winning papers and articles published in leading US and British management journals since the mid-1990s. We use this data to evaluate the scope of HR research in the field, the extent to which it has changed, and whether changes in this research have kept pace with changes that organizations face in the current global economy. Consistent with the strategic HR framework, we find that the question of the link between HR and performance has, indeed, become the dominant one among both micro- and macro-organizational scholars. Contrary to expectations, however, micro-level research continues to be more prevalent than macro-organizational studies; and we find little change in the subjects and sites of research or theoretical approaches adopted. These characteristics of HR research are in sharp contrast with the dramatic changes occurring in the world of work – suggesting a mismatch between what HR scholars study and what issues and dilemmas organizations face. Finally, by assessing similarities and differences between the American and British scholarship, we are able to suggest a research agenda, more relevant to the current global economy, which builds on the strengths of each tradition.     

Friend or Foe? The effects of contingent employees on standard employees' work attitudes

Using data from a large-scale national survey of employers and employees in Britain, we examine the impact of the presence of contingent employees on work attitudes of standard (full-time, indefinite-term) employees. Drawing on differing explanations for the increased use of contingent employment arrangements, we derive competing hypotheses about how this use affects standard employees' work perceptions and attitudes, and explore the impact of a number of potentially intervening factors. We find that contingent employees have little effect on standard employees' perceptions of work overload, but strongly reduce perceived job security, which in turn, mediates the negative effects of contingent employees on job satisfaction and organizational loyalty.     

Impatience implication of weakly Paretian orders: Existence and genericity

We study order theoretic and topological implications for impatience of weakly Paretian, representable orders on infinite utility streams. As a departure from the traditional literature, we do not make any continuity assumptions in proving the existence of impatient points. Impatience is robust in the sense that there are uncountably many impatient points. A general statement about genericity of impatience cannot be made for representable, weakly Paretian orders. This is shown by means of an example. If we assume a stronger sensitivity condition, then genericity obtains.
