Market driving strategies : Beyond localization
No full textAdaptation to local customer preferences may result in a more rapid market acceptance, and market orientation studies often propound that firms need to closely monitor changes in the marketplace and adapt to customer needs in order to enhance firm performance (Slater & Narver, 1995). However, firms operating in multiple markets may choose minimal adaptation to local market trends in favor of introducing proprietary value propositions that satisfy customers' latent needs (Ghauri, Elg, Tarnovskaya, & Wang, 2011; Harris & Cai, 2002). Scholars suggest that such firms are “market driving” (Jaworski, Kohli, & Sahay, 2000). This paper investigates how firms can be market driving in foreign markets. Findings suggest that market driving firms tend to possess certain capabilities in order to reconcile conflicting demands in the local markets and company strategies at the global level. Using network, knowledge transfer, branding and market orientation literature, the present study provides evidence on the capabilities that global firms possess in order to drive markets. Based on a survey of 110 international companies, this study shows that strong capabilities in configuration, networking, knowledge transfer and internal branding can lead to market driving behavior. This study is the first to carry out a systematic investigation of market driving behavior in international firms
Partnerships in cross-cultural marketing and retail internationalization: research propositions
No full textAn under-researched area in cross-cultural marketing is the multistep partnership between local retailers and multinational retailers. Local retailers not only bring in multinational retailers to their own country, but they continue to partner with the same multinational retailers to expand to adjacent countries. This increases the likelihood of consumer receptiveness to new-to-the-market retail concepts. Hence, the effectiveness of cross-cultural marketing is heightened through the partnership and localization expertise of the local retailer and the multinational retailer. The knowledge that this partnership brings can also encourage local retailers to develop their own retail concepts and expand these abroad. This chapter highlights the importance of studying the role of local retailers in cross-cultural marketing of new retail concepts. Drawing on Mathews’ newcomers’ theory and analyzing case histories, we argue that local retailers seek multinational partnerships to build up their resource base and develop other business operations. Moreover, such development engenders growth and makes internationalization possible for the local retailer.</p
Site-specific validation of turbulence models on large offshore wind farms for improving fatigue assessment
No full textWind turbines installed in a wind farm are typically subject to increased turbulence because they are in the wake of upstream wind turbines that generate additional turbulence. Accurate prediction of turbulence in wind farms is critical as it is proportional to wind turbine fatigue loads, power losses and prediction of wind farm lifetime. IEC Standard 61400-1 suggests the use of the semi-empirical turbulence model called Frandsen model, which was originally proposed in 1999. Since the development of the Frandsen model, the size of wind turbines and wind farms has increased significantly. Therefore, this work aims to determine the accuracy of two versions of the Frandsen model: Standard and Modified, when applied to large offshore wind farms experiencing a combination of atmospheric stability conditions. This is done by comparing the estimated wind farm turbulence under specific atmospheric stability conditions with measurements from Westermost Rough and Horns Rev 2. It was found that the atmospheric stability distribution and the distance of the upstream wake inducing wind turbine at the offshore site plays a significant role in the accuracy of the estimated turbulence from the Frandsen models. The estimated turbulence intensity from the Standard and Modified Frandsen models was found to be under-predicted with respect to the measured turbulence for all atmospheric stability conditions at both wind farms. For wind directions with wake flow for upstream wind turbines more than 10 rotor diameters away, the Modified Frandsen model showed better prediction of turbulence intensity compared to the Standard Frandsen model. On the other hand, for wind directions with wake flow for upstream wind turbines less than 10 rotor diameters away, the Standard Frandsen model showed better turbulence intensity estimation compared to the Modified Frandsen model. Among all atmospheric stability conditions, the turbulence intensity estimate was closest to the measured data for unstable conditions. It is suggested that this fact can be attributed to the presence of a significant number of unstable conditions in the offshore wind farms used for the design of the semi-empirical Frandsen model.Electrical Engineering | Sustainable Energy Technolog
The impact of multinational enterprises on sustainable development and poverty reduction: Research framework
No full textThe purpose of this chapter is to develop a framework that can be used to study the impact of multinational enterprises (MNEs) on sustainable development and poverty alleviation in developing countries. In the 3-year project awarded by the EC-FP7 program, six universities from Europe and three partners from developing countries participated: Brazil, Ghana, and India. For this purpose, a thorough literature review is done and a framework is presented. To confirm the conceptual framework, we performed several case studies with three MNEs in two countries, Ghana and India. Data collection was done through qualitative in-depth interviews with managers in the headquarters of MNEs, the subsidiaries, and the "linked" local firms and host governments. Results confirm our conceptual model that the autonomy of the subsidiary, strategies of MNEs, and local government policies play a major role in achieving positive externalities from MNE operations in developing countries. The key contribution of this study is the development of a relevant conceptual framework that can be used in the overall project. Our study confirms that an interaction between the MNE subsidiary and the local government is essential for the linkages and spillovers to occur that may benefit local economic development and poverty reduction in developing countries.</p
Regimental and Diet-o-therapy during pregnancy and their effects
No full textPrevention of health in the antenatal stage is essential for future generations' growth and development before entering this world. Care during pregnancy is called Tadbeer-e-Hamla from Unani perspective. According to the Tibb-e-Unani and ayurvedic medicine system, health restoration and maintenance in different conditions, even diseased or healthy, is achieved by managing lifestyle factors. This management is based on which type of condition you suffer and the signs and symptoms that diagnose this condition. Then this diagnosis is also confirmed by the Unani tools that are Pulse (Nabz), Urine (Baul), and Stool (Baraz). After securing the state of the body, treatment starts with four basic principles of management (Usool-e-Ilaj). These principles of management are regimental therapy (Ilaj-bil-tadbeer), Diet therapy (Ilaj-bil-ghiza), Pharmacotherapy (Ilaj-bil-dawa), and Surgery (Jarahat). In this paper, regimental treatments and diet therapy are described in detail during pregnancy
An Inter-firm Perspective on Market, Brand and Entrepreneurial Orientation: the Influence on Performance
No full textImpact of Domestic M&A on Acquirer Shareholder`s Equity: Evidence from Oslo Stock Exchange
No full textThe clear majority of research studies that has been conducted in the field of mergers and acquisition (M&A) are performance studies of acquirer post-M&A. Researchers has tried to get an insight into whether an M&A deal has had a positive or a negative effect on the acquiring company. In addition, most of these studies have been conducted on the US and UK market and hence the author wish to contribute to the existing literature by performing a specific study on the Norwegian market.
In the following thesis, I examine the short-term/immediate impact of selected domestic mergers and acquisition (M&A) deals on acquirer`s shareholder`s equity in the Norwegian market and I also examine whether this impact is influenced by the method of payment.
The author follow in the footsteps of numerous empirical researchers in the field of M&A and use event-studies to evaluate the performance of Norwegian M&A deals. The analysis investigates the Cumulative Abnormal Return (CAR) that measures a stocks unexpected returns and thus can be understood as the stock`s market reaction to the M&A announcement. The interpretation of CAR is that the stock price will on average react positively to M&A announcements when the Cumulative Average Abnormal Return (CAAR) and Average Abnormal Return (AAR) is greater than zero and statistically significant. The analysis considers selected domestic M&A deals on the Norwegian market in the period of 1995-2015 which add up to 38 deals that fulfills specific criteria`s.
HYPOTHESIS 1: Cumulative Average Abnormal Return (CAAR) is positive in the event-window
The results for CAAR show conflicting results and only significant values for the event-window of [-10, 10] and [-1, 1]. Due to significant conflicting results, Hypothesis 1 cannot be supported and hence the author has not been able to conclude whether Norwegian domestic M&A deals has created value or not.
HYPOTHESIS 2: Average Abnormal Return (AAR) is positive around the announcement date [0, 1]
The results for AAR shows that we have high statistically significant positive AAR around the announcement date. This indicates that the market views the M&A activity positively and hence Hypothesis 2 is supported.
HYPOTHESIS 3: Cash-only deals are positively related to CAAR
HYPOTHESIS 4: Mix-deal are positively related to CAAR
The results are not in line with the theoretical discussion in this thesis and not what the author would have expected. The results show that cash-only deals underperform both stock-only and mix deals.
Unfortunately, the results are not statistically significant and thus Hypothesis 3 and Hypothesis 4 are not supported.M-I
