Role of entrepreneur gender and management style in influencing perceptions and behaviors of new recruits: Evidence from the Islamic Republic of Iran

Entrepreneurs face considerable challenges in attracting prospective recruits and managing them in the absence of established norms and traditions. This research examines how gender and management styles of entrepreneurs impact new recruits’ attitudes including their cognitions, affect, and behaviors in new ventures. Results of two experimental studies conducted in the Islamic Republic of Iran demonstrate that women entrepreneurs are reacted to less negatively and considered more effective when they use directive management style. In addition, women entrepreneurs who employ directive style elicit superior performance from new recruits compared to those who rely on participative style. Management style does not appear to matter for attitudes towards men entrepreneurs. Implications and future research directions are discussed.     

Investigating the implications of business and culture on the behaviour of customers of international firms

For many years international firms have been leveraging from the consistent growth rate of the Indian economy and, considering forecasts, will continue to do so in the future. This study identifies factors that influence the behaviour of business customers of international firms in emerging markets such as India. Based on the extant literature and in-depth personal interviews with practitioners, combined with a field survey, the authors have tried to understand the impact these factors have on the behaviour of business customers of international firms. The data were useful for testing the model developed using regression analysis and were found to be significant. The model demonstrates that the behaviour of local firms as customers of international firms in emerging markets is governed by factors such as business risk and a propensity to business sustainability. The model will be useful for international firms who wish to operate in emerging markets through local business firms that seek to associate with international firms.     

Do sunspot numbers cause global temperatures? Evidence from a frequency domain causality test

This article applies the causality test in the frequency domain, developed by Breitung and Candelon (2006), to analyse whether sunspot numbers (used as a partial approximation to solar irradiance) cause global temperatures, using monthly data covering the time period 1880:1–2013:9. While standard time domain Granger causality test fails to reject the null hypothesis that sunspot numbers do not cause global temperatures for both full and sub-samples (identified based on tests of structural breaks), the frequency domain causality test detects predictability for both the full-sample and the last sub-sample at short (2–2.6 months) and long (10.3 months and above) cycle lengths, respectively. Our results highlight the importance of analysing causality using the frequency domain test, which, unlike the time domain Granger causality test, allows us to decompose causality by different time horizons, and hence, could detect predictability at certain cycle lengths even when the time domain causality test might fail to pick up any causality. Further, given the widespread discussion in the literature, those results for the full-sample causality, irrespective of whether it is in time or frequency domains, cannot be relied upon when there are structural breaks present, and one needs to draw inference regarding causality from the sub-samples, we can conclude that there has been an emergence of causality running from sunspot numbers to global temperatures only recently at cycle length of 10.3 months and above.     

Convergence of greenhouse gas emissions among G7 countries

The convergence of air pollutants is a major concern for policymakers since all the countries pursue the goal of allocating the emissions equally internationally in the future. Hence, the examination of the existence of convergence is important for the climate change protection of the earth. In this article, greenhouse gas (GHG) emissions convergence among the G7 countries for the period between 1990 and 2011 is examined using the pairwise testing technique proposed by that aims to analyse probabilistic convergence across a large number of cross-sectional units. Next, we proceed with multivariate tests for stability and the existence of unit roots. Finally, the analysis is complemented by the use of the panel stationarity test accounting for structural changes as proposed by Carrion-i-Silvestre et al. (2005) test. Overall, the results do not confirm the hypothesis of convergence for the countries in question, although, more recently, the countries have shown a small decline in their GHG emissions.     

Blind man's bluff: The ethics of quantity surcharges

Empirical evidence, including a recent field study in Northwest Indiana, indicates that supermarkets and other retail merchants frequently incorporate quantity surcharges in their product pricing strategy. Retailers impose surcharges by charging higher unit prices for products packaged in a larger quantity than smaller quantity of the same goods and brand. The purpose of this article is to examine the business ethics of such pricing strategy in light of empirical findings, existing government regulations, factors that motivate quantity surcharges and prevailing consumer perceptions.Omprakash K.

Improving R&D/Marketing relations: R&D's perspective

Abstract
Successful product innovation hinges on close R&D/marketing relationships, especially in technology-based organizations. However, there is evidence that linkage problems are common and when they are not overcome failure is the usual result.
R&D's perspective on what R&D, marketing and senior management can do to improve their relationship with marketing is presented. The recommendations are based on suggestions from R&D directors involved in new product development efforts in 83 technology-based companies. Also presented is how the need for integration has changed over time and where it is going in the future.     

Robust row-column designs for complete diallel cross experiments

This paper investigates the robustness of variance-balanced row-column designs for complete diallel cross experiments for estimating the comparisons among the general combining ability parameters against the loss of observations. A necessary and sufficient condition of robustness as per connectedness criterion is obtained. The robustness of optimal row-column designs of Gupta and Choi (1998) has been investigated for the loss of any m(≥1) observations in a column and for the loss of any two observations in the design. The study of robustness has also been conducted as per A-efficiency criterion.
