Multiple allocation hub location with service level constraints for two shipment classes

Sachin Jayaswal, Navneet Vidyarthi

European Journal of Operational Research

In this paper, we study a hub network design problem arising in the context of a third-party logistics (3PL) service provider, which acts as an intermediary between shippers and carriers. A 3PL service provider usually caters to different classes of shipments that require different levels of service, e.g. two-day delivery, next-day delivery etc. We, therefore, study the problem under stochastic demand from two classes of shipments, with one class receiving priority over the other in service at the hubs to maintain the different service levels required by them. To this end, we present two models for designing a capacitated hub network with a service level constraint, defined using the distribution of time spent at hubs, for each shipment class. The models seek to design the hub network at the minimum total cost, which includes the total fixed cost of equipping open hubs with sufficient processing capacity and the variable transportation costs. The network of hubs, given their locations, is thus modeled as spatially distributed priority queues. The resulting model is challenging to solve, for which we propose a cutting plane-based exact solution method.

National digital infrastructure and India’s health care sector: Physician’s perspectives

Rajesh Chandwani, Saneesh Edacherian and Mukesh Sud

The Qualitative Report

Patient-centric digital infrastructure can potentially enhance the efficiency of healthcare systems. However, even in developed nations, evidence suggests low adoption rates for such infrastructure and lack of support from clinicians is considered as one of the most critical hindering factors. In this study, we examine physicians' perceptions of the proposed large-scale information technology initiative in India that aims to transform the health sector and provide universal health coverage to all residents of India. We employed the information ecology lens to understand the broader changes in the healthcare system that could result from the initiative. We use focus group discussion and in-depth interviews to comprehend the perceptions of doctors about the initiative. Drawing upon Foucault’s conceptualization of power, we find that physicians, the key stakeholders in this initiative, are skeptical about the changes in the locus of power in the new ecosystem. Specifically, they perceive that knowledge power has shifted from a historical “expert knowledge power” to power related to “data management.” The physicians believe that changes are expected to manifest through monitoring, controlling, and managing the data rather than providing knowledge-based services. We present recommendations to engage physicians' perspectives in implementing large-scale patient-centric digital infrastructure.

Gold in household portfolios during a pandemic: Evidence from an emerging economy

Oindrila Chatterjee, Balagopal Gopalakrishnan, and Sanket Mohapatra

This paper examines how Indian households allocate their savings portfolio across gold, financial assets, and cash during the COVID-19 crisis. Our study relies on an extensive household survey in 142 districts across 21 states in India conducted during the 2020-2021 financial year. We find that the portfolio allocation of households in districts with a higher incidence of COVID-19 shifted towards gold during the pandemic compared to households in other districts. The shift towards gold is accompanied by a shift away from financial assets and other assets (primarily cash). A similar shift towards gold is observed for districts that experienced the most adverse economic impact--as measured by lower night-time lights intensity--during the pandemic. Households in districts with greater banking access and better health infrastructure show a smaller shift towards gold. A panel estimation with normal and COVID-19 period surveys confirms the baseline results. Our findings contribute to a better understanding of the role of economic crisis in shaping the financial decisions of households.

COVID-19 pandemic intensity, migration status, and household financial vulnerability: Evidence from India

Sanket Mohapatra, and Akshita Nigania

The COVID-19 pandemic adversely impacted many households across the world. Recent studies on the pandemic have focused on its impact on income, consumption, and poverty of households, but not directly on their financial well-being. Building on the prior literature on measures of financial vulnerability, this paper analyses the heterogeneous effects of COVID-19 on household financial vulnerability based on the geographical variation in the intensity of the pandemic in India and households’ migration status. Using a difference-indifferences approach and coarsened exact matching, we find a larger increase in household financial vulnerability in Indian districts that are more exposed to COVID-19 and those that experience a greater decline in night-time lights (a proxy for economic activity) compared to households in other districts. We also find that households with an out-migrant, particularly those with a female head, experience lower financial vulnerability during the pandemic, likely due to the financial contribution of migrants. However, financial vulnerability during COVID-19 is substantially higher for households that had an out-migrant in the prior period but not during the pandemic, with a larger effect observed for female-headed households. The findings of this paper contribute to a better understanding of the varied effects of the pandemic on households.

Disciplining Orders Under the National Financial Reporting Authority Framework: Stepping into a Strict Liability Regime

M P Ram Mohan and Vishakha Raj

The National Financial Reporting Authority (NFRA) was established to fill a gap in the oversight of auditors by independent regulatory bodies. Prior to the establishment of the NFRA, only the Institute of Chartered Accountants of India (ICAI), a self-regulatory body could bar auditors from practicing in the event that they had engaged in professional misconduct. This regime began to change as auditors engaged with public firms, bringing the securities regulator into the mix as well. The decisions of ICAI and SEBI have not followed a consistent approach. A finding of misconduct is often accompanied by a finding of gross negligence and the latter does not have a uniform definition. The NFRA, being a nascent authority has only begun to issue orders against auditors over whom it has jurisdiction. Its orders are based on the same substantive law relating to professional misconduct of auditors as the ICAI, however, NFRA orders have shown more consistency in their approach and outcome. This paper examines the decisions of the NFRA from 2020 till December 2022 and posits that the consistency in its approach has been achieved by developing a no-fault regime for auditors.
