The present study aims to investigate the impact of income inequality and economic growth on carbon dioxide (CO2) emission through the moderating role of innovation in China at national and regional levels. To test the hypothesised relationships, this study took the data from 1995 to 2015 and employed panel estimation. Findings of the whole analysis show that income inequality and economic growth influence CO2 emission in China. Moreover, technological innovation moderates the proposed link. However, the findings at the regional level are mixed, thus confirming the existence of regional differences. Policy implications are also discussed. ARTICLE HISTORY

Purpose The aim of this study is to examine the influence of workplace ostracism on deviant behaviour and testified the mediating roles of organisational identification, burnout and organisation-based self-esteem (OBSE) by using a parallel mediation model. Then, the moderating role of ingratiation in the interrelation between ostracism, the mediators and deviant behaviour is examined. Design/methodology/approach A survey questionnaire was used to collect data from nurses working in public sector hospitals in Pakistan. Nursing context is appropriate for the study because this occupation involves a greater extent of social interaction among peer nurses, doctors and administration in the provision of health services. A total of 417 nurses provided complete responses, and the study hypotheses were tested using the partial least squares structural equation modeling (PLS-SEM). Findings The study findings show that ostracism is positively related to deviant behaviour of nurses, indicating that workplace ostracism is an important predictor of deviant behaviour. Ostracised nurses experienced higher job burnouts and low OBSE as well as organisational identification. Results also show that ostracism promotes deviant behaviour by reducing OBSE and organisational identification. Moreover, results provide evidence that high ingratiation overcomes the detrimental effects of ostracism on both deviant behaviour and mediators. Originality/value The present study integrates the literature on ostracism and its attitudinal and behavioural outcomes and submits that ostracism negatively affects the attitudes of victims which in turn results in negative behavioural outcomes (i.e. deviant behaviour). This study also suggests ingratiation as a tactic to control the negative effects of ostracism.
