Does CSR Expenditure and Sustainability Reporting Improve Firm Performance? Mandatory CSR Regimes in India

This paper aims to investigate whether firms that comply with corporate social responsibility (CSR) expenditure and undertake voluntary sustainability reporting will have lower systematic risk and higher stock returns—the proxies for measuring firm performance—in mandatory CSR regimes in India. The instrumental approach of stakeholder theory asserts that firms considering stakeholders’ interests, including societal interest, are likely to show better firm performance compared to others. Therefore, on the basis of such a theory, this study attempts to link sustainability reporting and CSR compliance with firm performance. One-way Analysis of Variance (ANOVA) and post-hoc tests were used to examine the proposed hypotheses and analyze the results for firms meeting the criteria of CSR provisions and are listed in the National Stock Exchange (NSE) of India. The period of study covers four financial years from 2015–16 to 2018–19, after India mandated CSR expenditure on April 1, 2014. Results reveal that markets value those firms that meet the mandatory CSR expenditure requirement but do not undertake voluntary sustainability reporting. The findings offer important implications for firms, investors, and policymakers of countries, including those that are planning for CSR legislation

Combating COVID-19 with Proficiency and Precision

It has been two years since the first case of Coronavirus Disease-2019 (COVID-19) was detected in India in the state of Kerala in March 2020. (1) The Government and the citizens of India have united together to combat the virus since then. India is the largest democracy in the world and the second highest populous country with an estimated 1.36 billion population. The country has witnessed three major waves of the COVID-19 pandemic in the past 3 years, the second being the worse. In the month of June 2022, India has reported a cumulative total of approximately 4.34 crore confirmed cases of COVID-19 and 511,903 deaths. The state of Maharashtra has been the worst effected in all three waves. Presently the recovery rate from COVID-19 in India has crossed 98%. (2

VAGINAL VERSUS ABDOMINAL HYSTERECTOMY FOR BENIGN CONDITIONS

ABSTRACT Hysterectomy is the commonest gynaecological surgery performed in women. Present study involved 43 patients undergoing hysterectomy for benign condition. Out of 43 patients vaginal hysterectomy were performed in 26 cases and rest of the cases were performed by abdominal route. Out of 26 vaginal hysterectomy a case was converted into abdominal hysterectomy because of preoperative urinary bladder injury. Keeping all complications in mind we suggest that selective women requiring a hysterectomy for menstrual disorders from fibroid uterus or DUB may be offered a choice for vaginal hysterectomy. Key Words: Hysterectomy, uterine leiomyoma

Competing for Customers in a Social Network (R)

There are many situations in which a customer’s proclivity to buy the product of any firm depends not only on the classical attributes of the product such as its price and quality, but also on who else is buying the same product. Under quite general circumstances, it turns out that customers’ influence on each other dynamically converges to a steady state. Thus we can model these situations as games in which firms compete for customers located in a “social network.” A canonical example is provided by competition for advertisement on the web. Nash Equilibrium (NE) in pure strategies exist in general. In the quasi-linear version of the model, NE turn out to be unique and can be precisely characterized. If there are no a priori biases between customers and firms, then there is a cut-off level above which high cost firms are blockaded at an NE, while the rest compete uniformly throughout the network. Otherwise there is a tendency towards regionalization, with firms dominating disjoint territories. We also explore the relation between the connectivity of a customer and the money firms spend on him. This relation becomes particularly transparent when externalities are dominant: NE can be characterized in terms of the invariant measures on the recurrent classes of the Markov chain underlying the social network. Finally we consider convex (instead of linear) cost functions for the firms. Here NE need not be unique as we show via an example. But uniqueness is restored if there is enough competition between firms or if their valations of clients are anonymous
