Interval-Valued Intuitionistic Fuzzy WASPAS Method: Application in Reservoir Flood Control Management Policy

Interval-valued intuitionistic fuzzy sets (IVIFSs) are very flexible tool to cope with the uncertainty arises in multi-criteria decision making (MCDM) problems. In recent times, MCDM problems with interval-valued intuitionistic fuzzy information have achieved more attention from researchers in different areas and consequently, several MCDM methods have been extended for IVIFSs. In this paper, a novel approach based on WASPAS method is developed under IVIFSs. The developed method is based on the operators of IVIFSs, some amendments in the classical WASPAS method and a new process for calculation of criteria and decision experts’ weights. In process for calculating weights, new procedures is propoesd to compute the decision experts’ weights and criteria weights based on interval-valued intuitionistic fuzzy information measures (entropy, divergence and similarity measures) to achieve more realistic weights. Innovative information measures are developed based on the exponential function for IVIFSs to determine the weights of the criteria and decision experts. Since the uncertainty is an unavoidable feature of MCDM problems, the developed method can be a constructive tool for decision-making in an uncertain environment. Further, an uncertain decision making problem of reservoir flood control management policy is implemented with interval-valued intuitionistic fuzzy information, which reveals the effectiveness and reliability of the proposed IVIF-WASPAS method. To validate the result, comparative analysis with existing methods and sensitivity analysis are presented under interval-valued intuitionistic fuzzy environment.     

Significant issuance date returns in seasoned equity offerings: An options-based resolution of a puzzle

The significant negative issuance day returns associated with seasoned equity offerings (SEOs) have been a puzzle. In this paper we provide two explanations for this empirical regularity. First, using an option-based argument, we contend that issuance day returns are negative because of SEO related declines in volatility that reduce the option value of equity. Our empirical examination of US SEOs between 1983 and 2003 strongly supports this contention. Second, we find that the negative issuance date return is also related to market liquidity around the issuance date. Our findings are robust to various sub-samples and the uncertainty resolution argument, and are not driven by SEO buy-sell order imbalances.     

Political-economy of pension plans: Impact of institutions,gender, and culture

National pension systems are an important part of financial intermediation and worker welfare in most countries, but how and why do they differ internationally? Controlling for important political, economic and social institutions, we document that international differences in pension progressivity, or how pensions reflect lifetime earnings, are negatively related to masculinity, uncertainty avoidance, individualism, long-term orientation, employment rights, average pension levels, social trust and economic inequality. We also find that pension progressivity is positively related to the economic and societal role of women, the extent of Catholicism; as well as political voice and accountability. These results provide important insights for both public policy and MNC managers.     

Forecasting the Downturn of the Great Recession

We examine the quantitative forecasts of Wall Street Journal economists made during the Great Recession. The recession was not predicted in advance, and the severity of the decline was not recognized immediately. An important problem was that the real-time data did not reflect the actual state of the economy and contributed to the forecast errors. At times there was substantial disagreement among the forecasters. A time-series forecast disagreement might provide valuable information about impending recessions.     

Customer Satisfaction with Consumption Systems

ABSTRACT

Purpose: This research examines how satisfaction toward a product and its associated services offered together by a single provider jointly affects behavioral intentions toward the provider.

Design/methodology/approach: In this study, empirical tests were conducted using longitudinal data spanning 5 years from a multinational company that offers both products and associated services as part of a consumption system to their customers.

Findings: Results show a joint congruent effect of product and services satisfaction on behavioral intentions is linear and positive. It appears that offering great service cannot compensate for less-than-adequate satisfaction toward the product. The results further highlight decreasing customer sensitivity to improvements in both sources of satisfaction and imply that focusing on too high levels of one type of satisfaction for their customers can actually be counterproductive for firms.

Research Limitations: Our model was tested using the data obtained from a single firm. Future research could test this model with data from multiple firms in various different industries and establish broader generalizability to the findings.

Practical Implications: Findings provide managers with insights on how to allocate resources across product and service spaces and to manage product and services revenues over time. Results also indicate that customer behavioral intention ratings are more weighted on product quality over the service received by them. However, mere improvements in the product cannot provide the highest desired results and therefore quality improvements in the product need to be complemented by improvements in service quality.

Originality/Value: There is a rapid emergence of the phenomenon of manufacturers providing both products and services as an integrated consumption system to their customers. While the provision of both product and service subsystems by the same firm leads to certain synergies, there are obvious costs to the development of new service capabilities and coordination with existing product capabilities. Our research intends to address this issue.     

The R&D-Marketing Interface in High-Technology Firms

It has become part of the traditional wisdom that good relationships between the R&D and marketing departments are essential for effective new product development. But in so many firms it still just doesn't happen. How come? In this article, three pragmatic researchers, Professors Gupta, Raj, and Wilemon, take another look at what causes the significant barriers that exist at the interface of two of the key product innovation functions. What they discover is disagreement between marketing and R&D people about what they should do together. They also find that R&D people are the more reluctant cooperators. They draw some interesting opinions from the parties as to why the barriers exist.
