The role of brand communications on front line service employee beliefs,behaviors, and performance

Frontline service employees often vary in their delivery of the brand promise, leaving service firms with less direct control on other stakeholders’ brand perceptions. Internal branding efforts have been suggested as a way to improve employee performance. With this in mind, we develop a two-process model based on identification and internalization theories to explain how internally disseminating brand-relevant information to frontline employees enhances performance. Using multi-source data from the employees, managers, and customers of a business-to-business firm in the hospitality industry, we find that providing brand-specific information directly to frontline employees increases their identification with the brand (as evidenced in perceptions of firm authenticity) and enhances their internalization of brand values. Additional results suggest that firms should make an extra effort to communicate brand-specific information to frontline employees if they desire brand-consistent performance that is observable to managers and customers alike.     

Constraint-based ACO for a shared resource constrained scheduling problem

We consider a scheduling problem arising in the mining industry. Ore from several mining sites must be transferred to ports to be loaded on ships in a timely manner. In doing so, several constraints must be met which involve transporting the ore and deadlines. These deadlines are two-fold: there is a preferred deadline by which the ships should be loaded and there is a final deadline by which time the ships must be loaded. Corresponding to the two types of deadlines, each task is associated with a soft and hard due time. The objective is to minimize the cumulative tardiness, measured using the soft due times, across all tasks. This problem can be formulated as a resource constrained job scheduling problem where several tasks must be scheduled on multiple machines satisfying precedence and resource constraints and an objective to minimize total weighted tardiness. For this problem we present hybrids of ant colony optimization, Beam search and constraint programming. These algorithms have previously shown to be effective on similar tightly-constrained combinatorial optimization problems. We show that the hybrid involving all three algorithms provides the best solutions, particularly with respect to feasibility. We also investigate alternative estimates for guiding the Beam search component of our algorithms and show that stochastic sampling is the most effective.

The impact of agricultural innovation system interventions on rural livelihoods in Malawi

This study, conducted in central Malawi, assessed the way a research intervention using an agricultural innovation system affected rural livelihoods. Propensity score matching was used to establish one village as a control, against which the impact of the intervention on two study villages [0]could be measured. Using the Enabling Rural Innovation intervention as a case study, it was established that rural livelihood outcomes pertaining to crop and livestock production, household income, asset ownership and fertiliser use were significantly improved by this intervention. In-depth analysis, however, demonstrated that although the participating households had more robust livelihoods during the intervention, when the research programme was phased out the effect was reduced. The authors recommend that local agricultural extension officers should receive more capacity building and budgetary support to ensure proper understanding of agricultural innovation systems concepts and correct application so as to sustain their positive effects.     

Institutions,resources, and entry strategies in emerging economies

We investigate the impact of market‐supporting institutions on business strategies by analyzing the entry strategies of foreign investors entering emerging economies. We apply and advance the institution‐based view of strategy by integrating it with resource‐based considerations. In particular, we show how resource‐seeking strategies are pursued using different entry modes in different institutional contexts. Alternative modes of entry—greenfield, acquisition, and joint venture (JV)—allow firms to overcome different kinds of market inefficiencies related to both characteristics of the resources and to the institutional context. In a weaker institutional framework, JVs are used to access many resources, but in a stronger institutional framework, JVs become less important while acquisitions can play a more important role in accessing resources that are intangible and organizationally embedded. Combining survey and archival data from four emerging economies, India, Vietnam, South Africa, and Egypt, we provide empirical support for our hypotheses.

Evaluating irrigation investments in Malawi: economy‐wide impacts under uncertainty and labor constraints

Irrigation expansion is critical to increase crop yields and mitigate effects from climate change in Sub‐Saharan Africa, but the low profitability has led to little irrigation investments in the region so far. Using an integrated modeling framework, we simultaneously evaluate the returns to irrigation arising from both economic and biophysical impact channels to understand what determines the profitability of irrigation in Malawi. Our results confirm that the returns to irrigation cannot cover the costs in Malawi. While labor‐intensive irrigation expansion leads to unfavorable structural change in the short‐run, the profitability hinges on low irrigated yields that fall far from expectations due to insufficient input use and crop management techniques. On the other hand, we find that the nonmonetary benefits of irrigation regarding higher food security, lower poverty, and reduced vulnerability to climate change make investments in irrigation worthwhile to improve the livelihoods of smallholders.     

Determinants and Consequences of a Voluntary Turn Away from IFRS to Local GAAP: Evidence from Switzerland

Abstract

We examine determinants and consequences of a turn away from International Financial Reporting Standards (IFRS) to local generally accepted accounting principles (GAAP), thereby exploiting a unique feature of the Swiss setting in which listed firms are allowed to switch from IFRS to Swiss GAAP, all else being equal. We posit that net benefits of IFRS are less for small firms with higher insider ownership. In addition, we predict that the net benefits of IFRS are not constant over time because of changes in IFRS and/or changes in firm-specific circumstances. To the extent that the switching firms’ costs of IFRS reporting outweigh its benefits, we do not predict adverse capital-market effects after a switch. Consistent with predictions, we find that (a) small firms with higher insider ownership and fewer foreign investor holdings are more likely to switch, (b) increasing reporting costs as well as changes in firm-specific circumstances affect switching propensity, (c) switching firms substantially reduce their disclosures after they switch, and (d) switching firms neither experience a decrease in liquidity nor negative announcement returns. Overall, our findings are important for standard setters and securities regulators in shaping (future) reporting requirements for listed firms.     

Implications of the Dominant Design in Electronic Initiation Systems in the South African Mining Industry

This article analyzes an emerging technological innovation, namely, electronic initiation systems for mining explosives in South Africa. The concept of electronic initiation is presenting itself as a challenge to traditional initiation systems, particularly cap-and-fuse and shock tube technologies. From a technology strategy viewpoint, the challenge is to determine the nature of the managerial decisions that have to be addressed. The Utterback-Abernathy innovation model is used to assess the evolution of the emerging technology; it is found that the technology is still in the fluid phase and that a dominant design has not yet emerged. Since the dominant design is a very important milestone in the evolvement of the product with regard to both the technical and the business aspects, the immediate managerial focus should be on the evaluation factors that may influence the emergence of the dominant design. The emergence of a dominant design is, however, a complex process that depends on the interplay between a myriad of issues, including technological, market, social, economic, and related aspects. The paper anticipates the technological future of the innovation by exploring the factors that may influence the dominant design of electronic initiation systems, and casts the findings in a format that is useful for managerial decision support.     

Does Correlation Between Stock Returns Really Increase During Turbulent Periods?

Correlations betwen international equity markets are often claimed to increase during periods of high volatility. Therefore the benefits of international diversification are reduced when they are most needed, i.e. during turbulent periods. This paper investigates the relationship between international correlation and stock-market turbulence. We estimate a multivariate Markov-switching model, in which the correlation matrix varies across regimes. Subsequently, we test the null hypothesis that correlations are regime-independent. Using weekly stock returns for the S&P, the DAX and the FTSE over the period 1988–99, we find that international correlations significantly increased during turbulent periods.
