A theoretical framework of electronic word-of-mouth against the backdrop of social networking websites

This study proposed and tested a theoretical framework that explains electronic word-of-mouth (eWOM) against the backdrop of social networking websites (SNWs), which have gained substantial popularity among travelers. In particular, a United States (US) nationwide online survey was conducted and nine hypotheses were tested. The findings suggest that willingness to share knowledge and switching costs are positively related to eWOM communication. In addition, customer value (utilitarian) has positive relationships with willingness to share knowledge, perceived security, and switching cost, while customer value (hedonic) has positive relationships with willingness to share knowledge and switching costs. Last but not least, the findings indicate that perceived security does negatively impact eWOM. In light of the major findings, the article sets forth strategic implications for travel-related social networking websites.     

When do the stock market returns to new product preannouncements predict product performance? Empirical evidence from the U.S. automotive industry

Substantial research has examined how stock market reactions to marketing actions affect subsequent marketing decisions. However, prior research provides limited insights into whether abnormal stock returns to a marketing action actually predict the future performance resulting from that action. This study focuses on new product preannouncements (NPPAs) and investigates the relationship between short-term stock market returns to an NPPA and the post-launch new product performance under various industry and firm conditions. Findings based on a dynamic panel data analysis of 208 NPPAs in the U.S. automotive industry between 2001 and 2014 reveal that stock returns associated with an NPPA are not an appropriate forward-looking measure of future product performance. However, under specific conditions (i.e., when the preannouncement is specific, the preannounced new product has low innovativeness, the preannouncing firm has a high reputation and invests heavily in advertising, and the preannouncement environment is less competitive), abnormal stock returns to NPPAs actually predict the future performance of new products. Thus, this study extends the marketing–finance and innovation literature with its focus on the conditions that affect the predictive power of immediate stock returns for the future performance of new products.     

Financialization and Vested Interests: Self-Regulation vs. Financial Stability as a Public Good

I propose an institutionalist analysis of financialization through the lens of Thorstein Veblen, built on some peculiar characteristics of money and related financial instruments in a market-based capitalist economy. Following the case of the overcapitalization of farmlands, studied by Veblen (1919), I argue that modern capitalism is a financialized society dominated by vested interests that rely on financial liberalization-led speculative overcapitalization, often leading to a perverse accumulation process and resulting in systemic catastrophes. Consequently, one of the major constituent institutions of liberal finance, market-dependent selfregulation, proves unable to deal with society-level issues like financial stability. This latter issue must be handled at a systemic level, as a public good. Therefore, specific public regulation and action mechanisms must be designed to maintain society (and dominant vested-interests) within some viability limits to ensure a smooth functioning of the economy.     

Enterprise systems’ life cycle in pursuit of resilient smart factory for emerging aircraft industry: a synthesis of Critical Success Factors’(CSFs), theory,knowledge gaps,and implications

The research aims to investigate business value critical success factors (CSFs) of enterprise systems (ES) through their life cycle in pursuit of resilient smart factory for emerging aircraft industry. This article provides an extensive literature analysis of past 22 years based on conscientious criteria of authors: (i) who have published strategic content relevant to CSFs, (ii) received more than 300 citations and (iii) concurrently published two or more papers relevant to ES CSFs. The most cited strategic CSFs were termed as classical CSFs. The 22 CSFs were identified, validated and synthesised for better understanding of success across life cycle by aircraft industry experts. The top 10 empirically verified CSFs have numerous differences with past generic classical CSFs. This article canvases real insights of two distinct views: process and variance approaches of the ES CSFs. The process approach, which is a neglected research area, facilitates the researchers for identification of ES life cycle process coupled with a view of resource deployment when it is needed the most. While the variance approach facilitates practitioners and researchers in finding out which resource (CSF) is relatively more important. The significant findings for ES life cycle can help the practitioners and researchers to make rational decisions throughout the ES life cycle.     

A decision analytic approach for technology portfolio prioritization: aviation safety applications

A decision analytic approach for evaluating new aviation safety products and technologies is developed and demonstrated to consolidate five existing program assessment metrics to develop a unified metric that simultaneously considers the relative importance and contribution of each. This allows for a meaningful and objective evaluation and comparison of the National Aeronautics and Space Administration (NASA) Aviation Safety Program (AvSP) advanced aeronautical products and technologies. The resulting decision model is referred to as the Composite Program Assessment Score (CPAS). The CPAS includes the five existing metrics; technical development risk, implementation risk, fatal accident rate reduction, safety benefits and cost, and safety risk reduction, which are each defined and quantified by different sources. The CPAS involves the scaling and combination of these individual metrics. In this paper, two alternative combinatorial modeling approaches to calculate the CPAS are presented. The weighted sum model and an additive value theory model are compared and contrasted. The resulting CPAS metrics allow an overall comparison of all 48 of the NASA AvSP products and technologies. Currently CPAS is based on preliminary weight measures from subject matter experts to reflect the relative importance of each metric. Actual case studies of both linear and non‐linear value functions are demonstrated.     

Spillover effects on government bond yields in euro zone. Does full financial integration exist in European government bond markets?

This paper examines the time varying nature of European government bond market integration by employing multivariate GARCH models. We state that unlike other bond markets, in euro markets the default(credit) risk factor and other macroeconomic and fiscal indicators are not able to explain the sovereign bond yields after the beginning of monetary union. This fact might be counted as a signal for perfect financial integration. However, we also find that the global shocks affect Germany and the rest of euro bond markets in various levels, creating particular discrepancies in asset prices even we take into account the market specific factors. Different level responses of each euro market to the global shocks reveal that euro bond markets are not fully integrated with each other unlike the recent literature claimed. Besides, we explore that the global factors are effective for the volatility of yield differentials among euro government bonds.     

An optimization approach for brass casting blending problem under aletory and epistemic uncertainties

A critical process in brass casting is the determination of the materials and their quantities to be added into the blend. The reason of being critical is the uncertainty about metal percentages in scrap raw materials. In this paper, the aleatory and epistemic uncertainties, which are modeled by using probability and possibility theory, respectively, have been handled simultaneously in a blending optimization problem for brass casting and a solution approach that transforms the possibilistic uncertainties into probabilistic ones is proposed. A numerical example is performed by the data supplied from MKE brass factory in Turkey. The results of the example have showed that the proposed approach can be effectively used for solving blending problem including aleatory and epistemic uncertainties in brass casting and other scrap based production process.

The Policy Challenge with Floating Exchange Rates: Turkey’s Recent Experience

This paper evaluates the developments in the Turkish economy in light of the Central Bank of Turkey’s (CBT) policies during a recent period of floating exchange rate system (March 2001–July 2003). It is found that the CBT was effective in containing volatility and reducing the average inflation rate while there was a strong recovery of output. However, there are accumulated risks in the economy. Particularly, the extreme appreciation of the Turkish lira during this period and the record level of real interest rates give the impression that the current state of the economy is fragile. Unless the government accelerates the structural reform process and pursues sound fiscal policies to reduce the public sector borrowing requirement and the debt ratio, an adverse shock to the system may trigger a reversal of fortune.
