PTE,innovation capital and firm value interactions in the biotech medical industry

Unlike previous studies which only focus on the main effect between IC and FV, this research includes PTE with the gap of resource-based view. IC is a key element in creating a competitive advantage, as it has a great influence on FV. A company may put relatively less into IC if it demonstrates higher efficiency. However, previous studies have neglected the fact that relative efficiency and IC affect FV and stock returns directly and indirectly. The research period was from 2006 to 2010 and the main research methods include HRA and DEA. The main research findings include the following. (1) There is a space for improvement in terms of the total technical efficiency. (2) PTE has a significant moderating effect between IC and FV. (3) IC and PTE have a significant influence on FV. (4) Apart from PTE and stock returns, IC and FV show significant differences within the sub-industry.     

The political market for immigration restrictions: Model and test

This paper addresses the important question of whether public investment spending on economic infrastructure enhances economic growth in Mexico. It estimates a Cobb-Douglas production function that includes public infrastructure capital. Using cointegration analysis, the paper estimates a vector error correction model (VECM) for the 1995?–?99 period. The results suggest that there is a long-term stable relationship among the variables included in the VECM. The evidence also indicates that both public infrastructure spending and private capital formation have a positive and highly significant effect on the rate of output growth. Finally, the impulse response functions (IRF) and the variance decompositions (VDC) of the endogenous variables in the VECM suggest that the response of private capital to public infrastructure is positive while the reverse causation is not affirmed. From a policy standpoint, the findings call into question stabilization policies that disproportionately reduce public infrastructure to meet targeted reductions in the fiscal deficit (JEL, O1, O47, O54).

Four decades of negative word-of-mouth and negative electronic word-of-mouth: A morphological analysis

Customers voice their negative brand experiences to their family and friends in the form of negative word-of-mouth (NWOM). Web 2.0 enables the sharing of NWOM in electronic format on various social media sites, online customer review forums, and blogs, which is known as negative electronic word-of-mouth (NeWOM). Researchers need to study the spread of NWOM/NeWOM to prevent adverse consequences for companies and suggest an optimal response for its redressal. Existing literature review studies have focused on word-of-mouth (WOM) and electronic WOM (eWOM) and have considered both positive and negative WOM and eWOM concurrently. Past literature reviews have captured the breadth of the WOM domain, ignoring the depth. This research article contains a review of 282 journal papers capturing the depth of the extant literature by focusing solely on ‘negative’ WOM and eWOM (NWOM and NeWOM), and presents a broad view of the NWOM and NeWOM domains using morphological analysis (MA). This will help to conceptualize and categorize the existing state-of-the-art literature into broad dimensions and identify future research opportunities. The MA framework helps to bifurcate this literature into the following four dimensions: (i) nomenclature of NWOM and NeWOM, (ii) antecedents of NWOM/NeWOM, (iii) impacts of NWOM/NeWOM, and (iv) prevention and recovery response to NeWOM. Further dissection of these four dimensions leads to 15 sub-dimensions and 217 variants. Combinations of the 217 variants enable the identification of 550 novel future research opportunities in the area of NWOM and NeWOM.     

Multinational Enterprises’ Entry Mode Strategies in Syria and Jordan: The Impact of Ownership Advantages

This study addresses the issue of ownership advantages affecting multinational enterprises’ (MNEs) entry mode strategies in developing countries. Although a few studies have focused on such effects, very little attention has been devoted to the ownership advantages generated from the institutional environment of MNEs’ home countries. To bridge this gap, this study concentrates on three types of ownership advantages: intangible asset advantages (IAA), advantages of common governance (ACG), and home‐country‐specific advantages (HCSA). Using a sample of 303 foreign affiliates, this study empirically examines the choice of MNEs between a wholly owned subsidiary (WOS) and a joint venture (JV). The data were collected from senior executives of MNEs’ subsidiaries operating in Syria and Jordan. The findings of this study reveal that MNEs’ choice of entry mode strategies is significantly influenced by intangible asset advantages, advantages of common governance, and home‐country‐specific advantages. Hence, senior executives perceiving an increased importance of these assets will opt for a WOS rather than a JV when entering a new market in the Middle East. © 2015 Wiley Periodicals, Inc.

Is environmental labeling certification a “green passport” for firm exports in emerging economies? Evidence from China

As the demand for more environmentally friendly products continues to increase, environmental label certification (ELC), as a voluntary environmental practice (VEP), has become a commonly used strategy by firms responding the green demands of the international market. While ELC is playing an increasingly important role in global trade, how ELC affects firms’ exports, especially how it affects the exports of those firms in emerging economies, remains unknown. This study explores the impact of ELC on firms’ exports. Insights are provided from resource-based views (RBV) by analysing China's A-share listed manufacturing firms to estimate the impact of China's ELC on exports. Our empirical results show that ELC can promote firms’ exports, because ELC emphasizes firms to reduce pollutant from the source, thereby, brings about cost advantage and green product differentiated advantage to boost high-quality exports. Using a series of robustness tests, we provide corroborating evidence for our hypotheses. The export-enhancing effect of ELC is impacted by the institutional context of emerging economies, as specialized market intermediaries and greater openness to the global market strengthen the export-enhancing effect of ELC. This research not only contributes to the literature, but also provides a reference for policy-makers and managers in using ELC to develop green trade.     

How do economic,cultural, and global-connectedness distances moderate the effect of customers’ experiences on their intention to revisit non-indigenous restaurants? Evidence from Korean restaurants

In this study, we evaluate how the effect of customers' experiences on revisit intention for non-indigenous restaurants can be moderated by economic distance (ED), cultural distance (CD) and global-connectedness distance (GD) between the country of origin for a given non-indigenous restaurant and the customer’s resident country. Surveys were conducted in seven countries across three continents, and the levels of ED, CD and GD between Korea and the seven countries were used as moderators. The findings suggest that the types of food and staff are two elements that should be emphasized in countries that are relatively close to Korea. Conversely, elements like the atmosphere of the restaurant and word of mouth should be emphasized in countries that have greater distances from Korea. Of the three distances considered in the study, GD had the strongest moderating effect on the relationship between customers’ experiences and their intentions to return to the restaurant. As a whole, the results imply that ED, CD and GD are important points of reference when considering prior experience while selecting a target country based on the strength of the restaurant’s experience management.     

Extreme internal–external industrial-service flexibilities and interfirm cooperative networks in high-technology machine manufacturing

Most interfirm studies focus only on the strategies of strategic partnerships, such as joint ventures, technology transferring agreements, licensing agreements; the study here provides interfirm-network knowledge protocols for designing interfirm-service processes in the high-technology machinery industry (HTMI) by small-and-medium enterprise (SME) networks from the perspectives of extremely-rapid industrial-service flexibility (X-ISF). Based on the decision system analysis (DSA) method, this study constructs an X-ISF research model consisting of major variables of extremely-rapid internal ISF (X-I ISF), extremely-rapid external ISF (X-E ISF), and cooperative networks. This study applies a mixed methods (qualitative and quantitative) research design to understand interfirm-network decision-making and the influence of the antecedent conditions of internal and external X-ISF and cooperative upstream-to-downstream networks on firms' X-ISF performance. The study finds that the mutual relationships between X-I ISF and X-E ISF are substantially unbalanced — the impact on firm X-ISF performance by the external-to-internal (X-in) ISF is substantially greater than the impact from the internal-to-external (X-out) ISF. Recognize the need to lead with external-to-internal X-ISF to sustain the adoption-implementation of superior high-technology is the principal take-away strategy implication.
