This study examines the importance of game elements of the first set in Wimbledon matches in deciding the match outcome. We propose a LASSO-induced logistic regression model based on first set data to identify the variables that impact the match outcome. Our findings indicate that winning service points, average distance travelled, and rating points significantly impact match outcome. Additionally, we show the effectiveness of our proposed model in within-match forecasting during the first set, and it frequently performs better than other statistical and machine-learning approaches. We also discuss important managerial applications of our methodology for players, coaches, and other stakeholders.

Artificial intelligence and associated technology advances have progressively diffused from routine tasks to non-routine tasks, causing disruptions in the labour market. In this work, we study the effect of automation on the labour market outcomes for low-skilled and high-skilled workers. We use the agent-based modelling approach to model firms and workers as rational agents with defined objective functions, endowments, and interactions. Using extensive simulations, we analyse the emergent phenomenon of employment levels and wage inequality in the labour market under varying scenarios. The key findings of our simulations indicate that automation of routine tasks increases wage inequality, whereas automation of non-routine tasks reduces it. Based on our results, we propose policy prescriptions regarding the job categories in which automation can be introduced for societal benefits, the skill enhancement programme needed for the workers, and guidelines on the redeployment of labour displaced through automation.

The present study explores the impact of earnings management on the readability of management discussion and analysis (MDA) section of annual reports of 384 Indian firms for 1,160 firm-years. It also explores the moderating behaviour of cash in explaining the association between earnings management and MDA readability. Using fixed-effect regression, the study finds that firms that manage earnings by meeting or just beating the previous year earnings publish complex MDAs. Moreover, it documents the positive moderating role of cash in explaining this relationship. Multiple robustness tests confirm our findings across different years including the COVID-19 crisis period.

This study attempts to find the structural relationship between initiated and received work interdependence on resilience at work and personal vision. We found a direct relationship between initiated work interdependence and personal vision, mediating serially through learning orientation and resilience. Interestingly, there was an inverse relationship between received work interdependence and personal vision, mediating serially through learning orientation and resilience at work. The key feature of work restructuring was found to be the emergence of the gig economy, with conducive internal and external business environments as its facilitators.

The evolving literature on using Twitter to capture investor sentiment suggests that stock market performance is linearly associated with Twitter's public mood. We investigate whether investor sentiment determined by the Twitter sentiment index (TSI) has a nonlinear predictive power for stock market behaviour. Using a dataset of seven US stock markets, we apply the cointegration techniques to show the relationship between Twitter sentiment and stock market behaviour. The results suggest a dynamic nonlinear cointegrating relationship. During the short run, Twitter happiness has a substantial effect on stock market indices, while in the long run, it has a moderating effect. Twitter happiness has a dominant effect on the US stock market indices than unhappy Twitter. These results highlight Twitter's growing role in predicting the stock market behaviour and show that the TSI acts as a better predictor of investor sentiment.

Drawing support from the conservation of resources theory, cognitive appraisal theory and self-determination theory, we investigate the link between remote abusive supervision (RAS) and life satisfaction (LS) through the mediating roles of obsessive work passion (OWP) and work-to-life conflict (WLC). We also examine the moderating role of information and communication technology (ICT) usage through the underpinnings of self-determination theory. Hypotheses were tested using SEM on 236 adults working from home for an Indian ITES company. RAS is found to be negatively related to LS, and OWP and WLC positively mediate the relationship; additionally, ICT usage moderates between OWP, WLC, and LS.

We examine the effect of geographical indications (GIs) on India's agricultural exports. We combine a novel dataset of state-product-year level exports with data on registered GIs for agricultural products in India from 2004 to 2016. Our identification strategy relies on exploiting the within-state-product variation in exports over time in response to GI registration. We find a significant positive effect of GIs on agricultural exports. We also observe that this increase is driven by government-owned GIs, and by GIs in states with more efficient courts and better transport infrastructure. Finally, we find a shift in cropping pattern, especially towards the GI-tagged crops, albeit at the district level.

This study probes the relationship between price and traded volume in electricity exchanges worldwide. Deploying the generalised method of moments estimation on panel data from the day-ahead market of exchanges in 20 countries for the period 2015–2020, this study finds that an increase in the share of exchange-traded electricity in a country's total electricity consumption significantly reduces the price. A critical analysis of the Indian electricity exchanges in this study reveals that even after 13 years of operations, consumers do not derive surplus which is expected from commodity exchanges.

The study explores the impact of different dimensions of organisational culture on job performance and satisfaction level of employees via mediating effect of psychological capital. The cause-and-effect relationship of employees’ job performance with job satisfaction and satisfaction with life is determined. The structural equation modelling method is used for determining the relationship among factors. There is a significant and positive impact of organisational culture on employees’ job performance that indeed affects the job and life satisfaction level of people in the organisations. Psychological capital plays a significant partial mediating role between organisational culture and employees’ job performance.
