Purpose The purpose of this paper is to examine the effects of pricing mechanism on initial public offerings (IPOs) oversubscription in Pakistan. Design/methodology/approach This study used cross-sectional data to analyse 85 listed IPOs on the Pakistan stock exchange during the period of 2000-2017 to assess hypotheses related to influential determinants of IPO oversubscription. Accordingly, ordinary least square, robust regression and quantile regression approaches were applied in this study to evaluate the factors that influenced oversubscription. Findings The outcome displayed pricing mechanism is negatively significant with an oversubscription of IPOs. This indicates firms using the fixed-price mechanism signalled higher information asymmetry and uncertainty in their value. Thus, investors are aware that they will be offset with underpricing, and it is expected the demand will be higher for the particular IPOs. Research limitations/implications This study is entirely focused on the available information of prospectus that should not be ignored by potential investors at the time of subscription of IPO. Therefore, the study contributes to extending the available literature in signalling theory whereby issuers should consider using the book-building pricing mechanism in enhancing the efficiency of the IPO offer price during the listing. Originality/value This paper provides evidence for the determinants of the IPO oversubscription.

Purpose This study aims to examine the effects of green marketing tools on tourists’ behavioural intention to buy green products by measuring individuals’ subjective norms, attitudes and perceived behavioural control. Design/methodology/approach A total of 421 international tourists from several tourist attractions in Malaysia, selected through convenience sampling, participated in a survey. Findings The analysis results using partial least squares structural equation modelling suggest that behavioural intention of international tourists is firmly influenced by attitude, perceived behavioural control, subjective norms and green marketing tools. However, the subjective norm does not work as a mediator. Practical implications The relationships established in this study provide insight into hoteliers’ knowledge for further implementation of green marketing strategies (eco-label, eco-brand, environmental advertising), which can enhance green attitudes and behavioural intention of purchasing green products in the hospitality industry. Originality/value This study expands the theory of planned behaviour by including green marketing tools to measure international tourists’ green buying tendency in Malaysia.

Purpose The purpose of this study is to determine the impact of job security on doctors’ retention, with job satisfaction and job embeddedness as the mediators. In doing so, the authors seek to contribute to the existing literature by providing additional empirical evidence on the links between job security, job satisfaction, job embeddedness and employee retention by using social exchange theory. Design/methodology/approach An empirical study was conducted on doctors working in public hospitals in Pakistan. Data from selected public hospitals were collected using semi-structured questionnaires. The simple random sampling method was applied for participant selection and partial least squares-structural equation modelling was used for data analysis purposes. Findings The findings confirmed the direct and mediation relationships. Thus, all of this study’s hypotheses are supported. The results indicate that job security can improve doctors’ retention. Further, job satisfaction and job embeddedness play crucial roles in mediating the direct relationship. Originality/value This study elaborates job security in health-care sector of Pakistan and also provides empirical evidence of the antecedents and mediators of doctors’ intention to continue working in the health-care industry.

PurposeThe present study investigated the influence of country-level institutional quality on IPO initial return using World Bank Governance indices.Design/methodology/approachThis study analysed 84 IPOs listed on Pakistan Stock Exchange between 2000 and 2017 using cross-sectional data. The impact of country-level institutional quality on IPO initial returns was examined using ordinary least square, robust least square, stepwise least square and quantile regression.FindingsEmpirically, the values of political stability, government effectiveness and regulatory quality were positively significant, whereas rule of law and control of corruption were negatively significant in explaining the intensity of IPO initial return. The results also show the presence of significant risk in the market. Hence, investors were compensated with higher initial returns for weak country-level institutional quality. The results also reveal that improving country-level institutional quality would improve the financial market transparency, thereby reducing IPO initial returns.Originality/valueNo studies have been conducted regarding the influence of country-level institutional quality on IPO initial return in Pakistan. This study is a pioneering study that seeks to give insights into the link between these variables in the context of Pakistan.

PurposeThis study investigated the effect of pricing mechanism and oversubscription on the heterogeneity of investors' opinions on initial public offering (IPO) valuation.Design/methodology/approachBesides the ordinary least square method, this study incorporated robust least square, stepwise least square and quantile regression methods to investigate the aftermarket behaviour of investors using the price range on the first day of trading of 82 IPOs listed on the Pakistan stock exchange.FindingsThe aftermarket behaviour of investors was found to be significantly influenced by the pricing mechanism, oversubscription, financial leverage, political stability and the risk of IPO, whereas control of corruption showed an insignificant impact. Concurrently, the findings showed that pricing mechanism and oversubscription played a crucial role in determining the intensity of investors' heterogeneous opinions at high levels of significance.Originality/valuePricing mechanism and oversubscription not only signal the quality of IPOs but also provide an important means for reducing the information asymmetry associated with new listings. Based on the literature review, it was found that both the pricing mechanism and oversubscription have yet to be explored in investigating the aftermarket behaviour of investors using the price range in the Pakistan IPO market. This study suggests that book building pricing mechanism and oversubscription are associated with lower heterogeneity in investors’ opinions at a high level of significance.
