Purpose The purpose of this paper is to extent the theory of planned behaviour (TPB), when extended by self-identity and religious commitment (RC), and is able to predict Muslim consumers’ willingness to pay (WP) for certified halal food. Design/methodology/approach A survey of 277 Muslim consumers in Malaysia was conducted and the cross-sectional data were analysed using the partial least squares technique. Findings Attitude (ATT) and religious self-identity (RSI) were found to have a positive impact on WP for certified halal food. Additionally, RC has a positive effect on ATT and RSI and has a positive moderating effect on the relationship between perceived behavioural control and WP. Practical implications The findings can benefit halal food companies by offering an insight into the willingness of Muslim consumers to pay for certified halal food. Originality/value The findings contribute to the research on halal foods by illustrating the factors that determine Muslim consumers’ WP for certified halal food. This study also extends the understanding of the TPB to the halal food context.

Purpose This study aims to investigate the factors that motivate Muslim consumers to pay for halal-certified food. Design/methodology/approach Data were collected through a survey of 272 Muslim consumers in Malaysia. The data were analyzed using the partial least squares technique. Findings The results showed that animal slaughter, halal logo, food quality and religious commitment have a positive effect on the willingness to pay for halal food. Religious commitment positively moderates the relationship between storage and transportation and the willingness to pay for halal-certified food. Practical implications Policy makers as well as managers of halal food companies can benefit from this study which provides insight into ways to increase demand for halal food. Originality/value The findings contribute to the literature on halal foods by illustrating the factors that determine Muslim consumers’ willingness to pay for halal food. This study also extends the literature by testing the moderating role of religious commitment.

We categorized innovating firms in an ascending order as adopters, adapters, and creators to examine factors motivating these activities. For small firms, creation and adaption were significantly correlated with export orientation, engaging in collaborative research and development (R&D), receiving technical support from outside agencies, gaining technology from parent establishments, and supplying parts to multinationals. For medium-sized firms, R&D incentives, collaborative research, and accessing technology from parent plants were significant. Adoption in small firms was associated with export exposure and operating for 11 years or more. R&D incentives, collaborative research, and technology transfer from parent plants were negatively related to adoption in medium-sized firms.
