Assessing advertisement quality on C2C social commerce platforms: an information quality approach using text mining

Deepak Trehan and Rajat Sharma

Online Information Review

Purpose

The purpose of this paper is to test relevance of the information quality (IQ) framework in understanding quality of advertisements (ads) posted by ordinary consumers.

Design/methodology/approach

The main objective of this study is to assess quality ads posted on customer-to-customer (C2C) social commerce platforms from an IQ framework. The authors deployed innovative text mining techniques to generate features from the IQ framework and then used a machine learning (ML) algorithm to classify ads into three categories ‐ high quality, medium quality and low quality.

Findings

The results show that not all dimensions of IQ framework are important to assess quality of ads posted on the platforms. Potential buyers on these platforms look for appropriate amount of information, which is objective, concise and complete, to make a potential purchase decision.

Research limitations/implications

As the research focuses on specific product categories, it lacks generalisability. Therefore, it needs to be tested for other product categories.

Practical implications

The paper includes recommendation for C2C marketplaces on how to increase quality of ads posted by consumers on the platform.

Originality/value

This study has focused on the user-generated content posted by ordinary consumers on the C2C commerce platform to sell used goods. Though C2C model has been developed on ads posted on C2C platforms, it can be established for brands as it provides them with an insight into latent dimensions that a consumer shall look for in an ad on social commerce platforms.

Construction, validation and generalization of SERVSTRESS: a measure for service induced customer stress

Subhadip Roy and Varsha Jain

European Journal of Marketing

Purpose

The purpose of this study is to construct and validate a generalizable scale to measure service induced perceived stress for customers of personal services with a high level of intangibles having both online and offline components.

Design/methodology/approach

Five studies were conducted to this end. The first was qualitative and the rest were quantitative (survey) with a total sample size of 1,300. The last study was conducted in a different country than the first four.

Findings

The studies resulted in a five-dimensional SERVSTRESS scale to measure service induced stress for customers with the following dimensions, namely, psychological stress; information stress; complexity stress; personnel stress and outcome stress. The scale was tested in a nomological network.

Research limitations/implications

The present study addresses a hitherto unaddressed gap in marketing literature with the construction and validation of a scale to measure service stress of a customer (named SERVSTRESS) using data from five studies spanning two countries.

Practical implications

The SERVSTRESS scale is relevant for the practitioners as it adds more value beyond the traditional service quality measures and allows the marketer to understand the nature of the stressors (with a specific focus on which is going right and which is going wrong) in the service delivery and allow him/her to take remedial actions.

Originality/value

The originality of the study is in the creation of a new scale to measure personal service stress and uncovering its underlying dimensions.

Demand for Crop Insurance in Developing Countries: New Evidence from India

Ranjan Kumar Ghosh, Shweta Gupta, Vartika Singh, and Patrick S. Ward

Journal of Agricultural Economics

Determining farmers’ real demand for crop insurance is difficult, especially in developing countries, where there is a lack of formal financial sector integration and a high reliance on informal risk mitigation options. We provide some new estimates of farmers’ willingness-to-pay for insurance in the context of a large-scale subsidised programme in India. We conducted a discrete choice experiment with agricultural households across four states in India, enabling us to estimate preferences for specific insurance policy attributes such as coverage period, method of loss assessment, timing of indemnity payments and the cost of insurance. Our results suggest that farmers do value crop insurance under certain conditions and some are willing to pay a premium for such coverage in excess of the subsidised rates they are currently required to pay under this programme. In particular, farmers value the assurances that they will receive timely payouts when they incur losses, and may not have a strong preference for the method with which losses are assessed. On the other hand, farmers are quite sensitive to coverage periods. Our baseline assessment shows that when optimised to farmer requirements, there can be a sizeable demand for crop insurance by developing country farmers.

Does negative teacher behavior influence student self-efficacy and mastery goal orientation?

Kathan D. Shukla, Samvet Kuril, and Vijaya Sherry Chand

Learning and Motivation

In a hierarchical society such as India’s, negative teacher behaviors are often part of the routine. However, there is a gap in the literature investigating the influence of negative teacher behaviors (specifically admonishing and dissatisfied behaviors) on students’ mastery goal orientation (MGO) and self-efficacy for learning which are important for student success. Accordingly, we examined these associations in Indian middle schoolers (N = 6423) after controlling for prior year outcomes and demographics. The data were collected through paper and pencil-based surveys at the beginning and the end of the 2015−16 academic session. Teacher behavior was measured using the Questionnaire on Teacher Interaction (QTI) whereas self-efficacy and MGO were measured using the Motivated Strategies for Learning Questionnaire (MSLQ). The analysis involved structural equation modelling of admonishing and dissatisfaction behaviors and student self-efficacy and MGO where we controlled for students’ prior outcomes and demographics. The independent variables collectively explained 27.4 % and 22 % of the variation in MGO and self-efficacy. Higher levels of teachers’ dissatisfied behaviors reduced self-efficacy and MGO within one year. Teachers’ admonishing behavior was linked with lower self-efficacy. Implications for policymakers, administrators and teachers are discussed.

The doctrine of frustration under section 56 of the Indian Contract Act

M P Ram Mohan, Promode Murugavelu, Gaurav Ray, and Kritika Parakh

Indian Law Review

The performance of obligations under a contract may be hindered by unexpected supervening events, leading to contractual uncertainties. The doctrine of frustration paves the way for a just consequence of such an unfortunate event, which has happened without any fault of the contracting parties. The doctrine fills the void in a contract regarding supervening events, based on principles of fairness and equity. Considering the large implications on the obligatory and binding nature of a valid contract, it becomes important to analyse the factors that guide the courts to determine its application. Unlike common law, the Indian Contract law explicitly incorporates the doctrine of frustration under section 56 of the Contract Act. However, the evolution of this doctrine in India has been greatly influenced by English law. This paper attempts to restate the law on the doctrine of frustration as applicable in India.

Alternate solution approaches for competitive hub location problems

Richa Tiwari, Sachin Jayaswal, and Ankur Sinha

European Journal of Operational Research

In this paper, we study the hub location problem of an entrant airline that tries to maximize
its share in a market with already existing competing players. The problem is modelled as a nonlinear
integer program, which is intractable for off-the-shelf commercial solvers, like CPLEX and
Gurobi, etc. Hence, we propose four alternate approaches to solve the problem. The first among
them uses the Kellys cutting plane method, the second is based on a mixed integer second order
conic program reformulation, the third uses the Kellys cutting plane method within Lagrangian
relaxation, while the fourth uses second order conic program within Lagrangian relaxation. The
main contribution of this paper lies in the fourth approach, which along with refinements is the
most efficient. Many of the problem instances that were not solvable using standard techniques,
like the Kellys cutting plane method, have been solved in less than 2 hours of CPU time within
1% optimality gap.

Right of recourse claims based on latent defects in the nuclear energy sector in India: Brace yourself for fact-intensive disputes

M P Ram Mohan and Els Reynaers

The University of Pennsylvania Asian Law Review

This working paper is focused on trying to interpret the meaning of "latent defects" and analysing how a case were to unfold if an operator of nuclear installation were to exercise its right of recourse against a supplier in the event of supply of equipment or material with latent defects, as envisaged under the unique Section 17(b) of the Civil Liability for Nuclear Damage Act, 2010 (CLND Act), as adopted by the Indian Parliament. Therefore, this paper presumes and builds on the assumption of some prior knowledge of general nuclear law principles as well as the CLND Act and related debates. We welcome comments on any part of the paper.

Ripples on financial networks

Sudarshan Kumar, Avijit Bansal, and Anindya S. Chakrabarti

The European Journal of Finance

In the financial markets, asset returns exhibit collective dynamics masking individual impacts on the rest of the market. Hence, it is still an open problem to identify how shocks originating from one particular asset would create spillover effects across other assets. The problem is more acute when there is a large number of simultaneously traded assets, making the identification of which asset affects which other assets even more difficult. In this paper, we construct a network of the conditional volatility series estimated from asset returns and propose a many-dimensional VAR model with unique identification criteria based on the network topology. Because of the interlinkages across stocks, volatility shock to a particular asset propagates through the network creating a ripple effect. Our method allows us to find the exact path the ripple effect follows on the whole network of assets.
