A regularized low Tubal-Rank Model for high-dimensional time series data

Samrat Roy, George Michailidis

High dimensional time series analysis has diverse applications in macroeconometrics and finance. Recent factor-type models employing tensor-based decompositions prove to be computationally involved due to the non-convex nature of the underlying optimization problem and also they do not capture the underlying temporal dependence of the latent factor structure. This work leverages the concept of tubal rank and develops a matrix-valued time series model, which first captures the temporal dependence in the data, and then the remainder signals across the time points are decomposed into two components: a low tubal rank tensor representing the baseline signals, and a sparse tensor capturing the additional idiosyncrasies in the signal. We address the issue of identifiability of various components in our model and subsequently develop a scalable Alternating Block Minimization algorithm to solve the convex regularized optimization problem for estimating the parameters. We provide finite sample error bounds under high dimensional scaling for the model parameters

Engaging customers and suppliers for environmental sustainability: Investigating the drivers and the effects on firm performance

Amalesh Sharma, Sourav Bikash Borah, Tanjum Haque, Anirban Adhikary

While firms engage stakeholders in their sustainability practices to contribute to a better world resiliently and responsibly, little is known about what drives their ability to generate customer engagement (CE) and supplier engagement (SE) for sustainability purposes. This paper identifies, theorizes, and empirically validates the differential roles of board oversight and incentivization, along with contingencies (a chief marketing officer’s (CMO) presence and governance disclosure), in driving CE and SE. Using data from 308 firms, the paper finds that while board oversight and incentivization positively affect CE, only incentivization positively affects SE. The paper also finds significant moderation effects of CMO presence and governance disclosure. Through multiple post hoc analyses, the paper explores how CE and SE influence firm performance. The paper provides a nuanced understanding of incentive types’ effects and contributes to the literature on grand challenges connecting firms’ strategies and sustainability objectives to customer and supplier engagement.

Gender diversity and inclusion on Indian boards: Post the introduction of the mandate in 2015 and 2019

"Neharika Vohra, Kashika Sud, Chayanika Bhayana"

The purpose of this study is to investigate the impact of quota requirements on the proportion of women serving on corporate boards in India. By examining not just the numbers but also the composition of women directors, including their profiles—age, education and professional experience, directorship type, appointment nature, industry representation—as well as patterns in their participation in board committees, compensation, tenure, and reasons for leaving, the study aimed to understand the extent to which boards have leveraged the presence of women on boards. The study includes all 1944 National Stock Exchange (NSE)-listed companies to whom the mandate applies. The results show an increase in the number of women on boards after the quota mandate; however, there is also a rise in the same women serving on multiple boards around the date of compliance to the quota mandate, suggesting symbolic inclusion of women on boards. Symbolic management was also evidenced in a few women holding chairperson positions, and proportionately, women’s leadership in committees such as audit committees being lower than their board presence. This research offers insights into the actions of Indian corporates to comply with the mandate and yet uphold the status quo, thus being symbolic in meeting the mandate.

Conceptualizing "systemically important technological institutions" as too big to fail entities: Moving the insolvency goal post

M P Ram Mohan, Sai Muralidhar K

The concept of Too Big To Fail (TBTF) has, for a long time, been associated with systemically important banks, insurance companies, and other financial institutions. The emergence of Big Tech companies, which permeate global markets, challenges the traditional notions of TBTF. Big Tech companies’ growing size and interconnectedness to the global economy have led to concerns emerging in the domains of antitrust law, data privacy laws, and financial stability. A key facet of financial stability regulation is the development of robust insolvency resolution frameworks to deal with potential failures of TBTF companies. This Article analyses whether Big Tech companies pose systemic risks to the financial system and the broader economy and, consequently, if they are TBTF, should there be special insolvency resolution frameworks akin to other systemically important institutions. The systemic risks Big Techs pose today may be substantially higher than traditional TBTF firms due to their deep interconnectedness with financial institutions. The Article explores the concept of Systemically Important Technological Institutions (SITI) and the challenges in designating them as TBTF.

Political mobilization of farmers in India: A case study of Bharti Kisan Union (Ekta Ugrahan) in Punjab

P H Shyam, Naresh Singla, Sukhpal Singh

Growing agrarian contradictions and peasant protests globally are seen as outcomes of the commercialization of agricultural production systems. The Indian Punjab is one such site that has also witnessed a high degree of agricultural commercialization, and farmers’ movements and protests are attributed to growing discontentment among peasantry due to the emergence of agrarian crises. This has led to massive farmers’ movements and protests through their unionization over time. These protests received global limelight during the introduction of three farm laws by the union government of India in 2020, which were repealed in 2021. This necessitates understanding the organizational structure and functioning of unions; their social composition, mobilization strategies and role of gender. This article examines the evolution and strategies of Bharti Kisan Union (Ekta Ugrahan, ekta meaning united), which is the largest farmers’ union in Punjab and one of the largest in India. Using a mixed-method approach of research, which included interviewing union member farmers and agricultural workers through a semi-structured schedule and conducting focused group discussions with block presidents and executive committee members, the study finds that the unionization of farmers has accelerated the process of rural democratization. However, active persuasion of social reforms along with other agrarian issues in rural society by the unions is needed to bring social inclusiveness to make rural development process pro-poor and inclusive.

Contesting social responsibilities of business: Centring context, experience, and relationality

Premilla D'Cruz, Nolywe Delanon, Arno Kourula, Jeremy Moon, Lauren McCarthy, Laura Spence

This introduction, and the special issue on ‘Contesting social responsibilities of business: Experiences in context’ it frames, addresses the neglected question of the experience of contestation in the terrain of the social responsibilities of business. It re-conceptualises the social responsibilities of business by advancing research grounded in a relational perspective, exploring and highlighting different forms of contestation of these social responsibilities, and centring the role of context by focusing especially on contestation in overlooked geographical settings and sites of marginalisation. Contextualising contestation in this way centres silenced and/or ignored voices, generates meaningful theory, and offers an innovative critical lens on business–society relations.

Making a new beginning on farm reforms

Satish Y. Deodhar, Vijay Kelkar

Minimum support price is not tenable on the grounds of impracticality of its measurement, lack of reach, financial implications, negative externalities associated with wrong incentives, and inefficiency in its execution. Alternatively, an agricultural and food marketing council on the lines of the Goods And Services Tax Council comprising representatives of the union and state governments can be constituted. It requires creating a comprehensive mechanism of direct benefit transfer and structural adjustment programme to provide production-limiting and production-switching incentives, compensation to agricultural produce market committees for loss of revenue for some period after nationwide integration of agricultural markets, and basic income to farmers.

Assessment of marketing channel choice and its impacts: The case of paddy smallholders in India

Sonalee Chauhan, Poornima Varma, Sukhpal Singh

Market access for smallholders is a key policy issue in developing economies. However, smallholders often face barriers in accessing remunerative marketing channels. Combining the theoretical framework drawn from resource-based view, social exchange, and transaction cost theory, we jointly estimate the determinants of marketing channel choice and the impact of channel choice in a joint framework. Results show that households’ resource endowments and social capital influence channel selection decision. Paddy sales through government agencies help farmers realize higher prices because of the higher government support prices and proximity to farms, whereas sales through licensed traders operating in the regulated markets (APMC) results in reduced paddy prices due to high transportation costs. Furthermore, smallholders preferring government agencies, processors, and licensed traders over village traders realize greater farm income. Reasons for such findings can be deduced to be the result of low marketable surplus for smallholders selling to village traders.

Can biofuels help achieve sustainable development goals in India? A systematic review

Prantika Das, Chandan Kumar Jha, Satyam Saxena, Ranjan Kumar Ghosh

Biofuels are expected to play a pivotal role in developing economies' transition towards net-zero emissions. However, their promotion can cause multifaceted sustainability concerns. National biofuel policies often align with the optimistic discourse surrounding biofuels but may lack comprehensive measures to simultaneously address all sustainability risks. This study conducts a systematic review to evaluate the sustainability performance of biofuels and examines their implications for advancing the Sustainable Development Goals (SDGs). A total of 12 sustainability indicators were identified as economic, social, and environmental priorities. Biofuel linkages with 8 SDGs, 21 targets, and 22 indicators were mapped. The analysis revealed a wider coverage of sustainability impacts associated with biodiesel compared to ethanol feedstocks for India. Notably, the sustainability effects of biofuels exhibited considerable variability across different spatial scales. Irrespective of the biofuel types, negative sustainability outcomes were found to be associated with socio-economic indicators related to food security, livelihood, and income, and environmental indicators like land use. Positive sustainability effects were observed for environmental indicators like water and soil quality, biodiversity, and ecosystem services. The study identifies policy gaps in addressing localized adverse effects of biofuels, emphasizing the need to align biofuel strategies with SDGs for more comprehensive and sustainable biofuel development in developing countries.

What money couldn’t buy: Social protection for migrants in India’s lockdown

Karan Singhal, Ankur Sarin, Advaita Rajendra

We analyze findings from a large-scale survey of over 11,000 respondents across 64 districts in India, conducted between December 2020 and January 2021 to examine the impact of the lockdown on internal migrants in India. We find that compared to the households without migrants, households with migrants were relatively advantaged in income levels before the pandemic but faced more severe food and financial vulnerability even nine months after the first lockdown. In addition, governmental social security support was more difficult to access for households with migrants. The paper joins several scholars in arguing for greater policy attention and social protection for migrants.
