Abstract

Purpose

The purpose of this paper is to analyze the relationship between new product diffusion and consumer internet search patterns using big data and to investigate whether such data can be used in forecasting new product diffusion.

Design/methodology/approach

This research proposes a new product diffusion model based on the Bass diffusion model by incorporating consumer internet search behavior. Actual data from search engine queries and new vehicle sales for each vehicle class and region are used to estimate the proposed model. Statistical analyses are used to interpret the estimated results, and the prediction performance of the proposed method is compared with other methods to validate the usefulness of data for internet search engine queries in forecasting new product diffusion.

Findings

The estimated coefficients of the proposed model provide a clear interpretation of the relationship between new product diffusion and internet search volume. In 83.62 percent of 218 cases, analyzing the internet search pattern data are significant to explain new product diffusion and that internet search volume helps to predict new product diffusion. Therefore, marketing that seeks to increase internet search volume could positively affect vehicle sales. In addition, the demand forecasting performance of the proposed diffusion model is superior to those of other models for both long-term and short-term predictions.

Research limitations/implications

As search queries have only been available since 2004, comparisons with data from earlier years are not possible. The proposed model can be extended using other big data from additional sources.

Originality/value

This research directly demonstrates the relationship between new product diffusion and consumer internet search pattern and investigates whether internet search queries can be used to forecast new product diffusion by product type and region. Based on the estimated results, increasing internet search volume could positively affect vehicle sales across product types and regions. Because the proposed model had the best prediction power compared with the other considered models for all cases with large margins, it can be successfully utilized in forecasting demand for new products.

Abstract

Purpose

The e-Government has a potential to entrench Good Governance in Pakistan. However, this technology could not be successfully developed and implemented in public sector – despite of efforts made by the Government. Consequently, public sector is suffering from bad Governance, which ultimately affects the Governance as well as e-Government ranking of Pakistan in the globe – as indicated by the UN surveys and other relevant indices. This paper aims to propose a novel techno-policy framework for its successful implementation by considering all relevant critical success factors (CSFs) and determining their relative importance from policymakers’ perspective. Further, it aims to excerpt the root causes of e-Government failure in Pakistan and to derive valuable policy implications for its success in the public sector.

Design/methodology/approach

The techno-policy framework was developed by identifying all the CSFs and assimilating them by deploying the analytic hierarchy process (AHP) approach. The survey instrument was designed to compare all the CSFs on the basis of AHP scale and to collect the socio-demographic data. An interview based survey of all the concerned stakeholders was conducted to know their perspective about the proposed framework and to determine their relative importance about all the CSFs. Finally, the empirical estimations were performed by using the Expert-Choice decision-making system.

Findings

The analysis of empirical results depicts that among CSFs’ main-categories – Governance is the most important; whereas, the Management and Resources are relatively more important; however, the Socio-Economics is relatively less important for the e-Government success in Pakistan. Further, among CSFs’ sub-categories – Political, Managerial, Legislative, Non-Technical, and Technical are relatively more important than Social, Economic, and Scope for the e-Government success in Pakistan. Lastly, among all CSFs – Political Stability, Managerial Strategy, ICT Policies, Funding, Portal Technology, Education & Skills, Cost, and Autonomy are the most important factors of their respective categories, and which can positively affect the e-Government success in Pakistan.

Research limitations/implications

This study fills the gap caused by paucity of literature in terms of empirical based techno-policy research in the e-Government domain – from implementation perspective. Further, it serves as a prototype for the prospective researchers, who aim to conduct policy oriented research toward e-Government development in their respective regions.

Practical implications

The key findings, policy implications & recommendations of this study are quite valuable and of practical significance for the government, policymakers, practitioners, researchers and all the concerned stakeholders and beneficiaries. Further, this study paves a way forward toward entrenching the Good Governance in Pakistan.

Originality/value

This study contributes in several ways. It highlights the significance of e-Government as a technology for attaining Good Governance in Pakistan. Further, it presents consolidated view of all the concerned stakeholders toward the successful implementation of all e-Government programs in Pakistan. Finally, it provides a guideline for the government agencies to formulate their e-Government policy and strategy as per the needs of all stakeholders in Pakistan.

Abstract

Purpose

The purpose of this paper is to evaluate the perceptions of Nigerian banking customers regarding customers’ evaluation of their banks service quality based on their banks actual performance on current banking service delivery.

Design/methodology/approach

A survey has been used to collect primary data and 1,245 usable questionnaires were used in the analysis. A conjoint analysis with stated preference data were used to construct the consumers’ behavior, while discrete choice method was employed to evaluate the preferences. More information was obtained by in cooperating heterogeneity into the model by the random coefficient and the test variance with the primary attributes and social demographics and individual characteristics.

Findings

Discrete choice analysis shows that bank management should focus on: reduction of transaction errors, transaction cost, waiting time and initial online learning time. This four attributes have strong impact on customer’s satisfaction depending on quality performance. Relative to other services the reduction in waiting time and transaction cost are the most important services to the Nigerian banking customers. Other findings of willingness to pay and consumer preference for other attributes reveal more information for improved banking policies.

Research limitations/implications

The sample only focussed on the urban areas and did not consider rural dwellers. Future research should aim to improve on these by including a variable in the utility set up that captures the distance of the respondent to the main city.

Practical implications

Nigerian banking customers do not care about a friendly smile as customer care. Rather, they value more on the waiting time and transaction cost showing that convenience and cost dimensions have strong and direct effect on service quality. Other dimensions identified includes, reliability, product portfolio, security and privacy, ease of use, accessibility, and competence and credibility.

Originality/value

This study has drawn on a sample of 1,245 Nigerian banking customers and evaluating how the survey respondents perceive their respective banks’ performance by their evaluation of the current banking service delivery.

Abstract

Purpose

The purpose of this paper is to examine the factors that influence e‐government adoption in Cambodia as one of the Association of Southeast Asian Nations (ASEAN) member states.

Design/methodology/approach

This study uses the technology acceptance model (TAM), the extended TAM (TAM2), the diffusion of innovations (DOI) theory, and trust to build a parsimonious yet comprehensive model of user adoption of e‐government. The authors test the model with an empirical study. Data are collected from a total of 112 public officers in 12 ministries in Cambodia. The research model is then assessed with multiple regression analyses.

Findings

The findings in this study show that the determinants of the research model (perceived usefulness, relative advantage, and trust) are support. At the same time, the important determinants of perceived usefulness include image and output quality.

Practical implications

The study would help government policy decision makers design and implement policies and strategies to increase the adoption of e‐government services in Cambodia as well as in other countries, particularly ASEAN member states that have a similar situation.

Originality/value

This paper is one of a few studies on e‐government adoption in ASEAN and the first study on e‐government adoption in Cambodia.

Abstract

Purpose

The purpose of this paper is to investigate factors influencing end‐user acceptance and use of government administration information system (GAIS).

Design/methodology/approach

A conceptual structural model of end‐user acceptance and use of the GAIS was developed with technology acceptance model as a theoretical background and tested using a structural equation modeling with partial least squares (PLS) approach on a data collected from a survey among 112 public officers in 12 ministries in Cambodia.

Findings

The results indicate that the factors influencing end‐user adoption of the GAIS are significantly affected by perceived usefulness, relative advantage, and trust. Perceived usefulness of the GAIS is directly affected by subjective norm, image, output quality, and perceived ease of use.

Practical implications

The results are of practical significance to all those interested in this area, mainly the government policy makers and practitioners in Cambodia's public services.

Originality/value

The paper is the first to investigate end‐user adoption of the GAIS. It is unique to Cambodia. It adds to the limited literature in e‐government in Cambodia. Simultaneously, the PLS approach use in this study is quite unique with government information system research. As such, it contributes to the methodology development in the government information system research field.

Abstract

Purpose

The purpose of this paper is to explore the factors determining which communication mediums influence a given consumer deciding to purchase a specific product.

Design/methodology/approach

Using a consumer survey and a multivariate probit (MVP) model, the authors explore consumer information searches related to purchases in nine categories: milk, instant noodles, shampoo, mobile phones, televisions, cars, mobile communication services, credit card services, and life insurance.

Findings

The media channels that motivate a given consumer to make a given purchase vary depending on both socio-demographic variables and product categories.

Practical implications

As consumers can now obtain product information through different and multiple media channels according to their personal characteristics and the category of the product they seek to purchase, these findings will help companies develop media planning strategies that will effectively target specific market segments.

Originality/value

Unlike previous studies, the authors consider which media channels actually affect a consumer’s product purchase decisions, and the authors do so across product categories and media types to provide practical implications for media planning. Furthermore, this is the first application of the MVP model in this context.
