Abstract

Purpose

This paper aims to propose a framework based on the unbiased extreme value volatility estimator (namely, the AddRS estimator) to compute and predict the long position and the short position value-at-risk (VaR) and stressed expected shortfall (ES). The precise prediction of VaR and ES measures has important implications toward financial institutions, fund managers, portfolio managers, regulators and business practitioners.

Design/methodology/approach

The proposed framework is based on the Giot and Laurent (2004) approach and incorporates characteristics like long memory, fat tails and skewness. The authors evaluate its VaR and ES forecasting performance using various backtesting approaches for both long and short positions on four global indices (S&P 500, CAC 40, Indice BOVESPA [IBOVESPA] and S&P CNX Nifty) and compare the results with that of various alternative models.

Findings

The findings indicate that the proposed framework outperforms the alternative models in predicting the long and the short position VaR and stressed ES. The findings also indicate that the VaR forecasts based on the proposed framework provide the least total loss for various long and short position VaR, and this supports the superior properties of the proposed framework in forecasting VaR more accurately.

Originality/value

The study contributes by providing a framework to predict more accurate VaR and stressed ES measures based on the unbiased extreme value volatility estimator.

Abstract

Purpose

The purpose of this study is to examine the current state of sustainability efforts within the field of supply chain management, more specifically supply chain logistics operations, and to identify opportunities and provide recommendations for firms to follow sustainable operations. This study also aims to stimulate further research within the area of sustainable logistics operations.

Design/methodology/approach

The reasons why it is important to implement sustainability into supply chain operations is discussed. Based on a review of the extant literature, various areas within the logistics function where sustainability can be implemented are then presented. Some short‐term and long‐term recommendations for the successful implementation of sustainability in the logistics function of supply chains are provided.

Findings

There has been very little work done to understand the role and importance of logistics in an organization's quest towards sustainability. For firms to implement a sustainability strategy in their supply chain operations, the logistics function needs to play a prominent role because of the magnitude of costs involved and the opportunity to identify and eliminate inefficiencies and reduce the carbon footprint.

Practical implications

Firms in their quest for sustainable logistics operations must start early and start simple. A top management commitment is required for such efforts to be successful. Also, firms need to be able to visualize and map out their supply chains and benchmark their sustainability efforts with other firms in their industry.

Social implications

Firms need to follow sustainable practices in their overall operations and in their logistics operations in particular because not only does it have financial and other intangible benefits, but it is also the right thing to do. Firms have a great social responsibility especially with respect to use of non‐renewable sources of energy and materials and also with respect to how their products are used and handled once they reach the end of their life cycles.

Originality/value

This paper is the first of its kind which examines the state of sustainability within the field of supply chain logistics operations and identifies areas and sets the agenda for future research in this field.

Abstract

Purpose

Large retailers and various government agencies have backed off from their earlier radio frequency identification (RFID) mandates. The RFID industry has also matured. The purpose of this paper is to examine RFID implementation in warehousing, utilizing empirical data to determine how the warehousing industry is changing with respect to RFID implementation.

Design/methodology/approach

An online survey was sent to Warehousing Education and Research Council (WERC) members at manufacturing firms, third party warehousing/logistics providers, wholesaler/distributors, and retail firms, to determine whether they are implementing RFID technology and what challenges they are facing.

Findings

Compared to an earlier study, it was found that fewer organizations are considering the technology. The respondents in general were less optimistic and concerns still exist on return on investment (ROI), potential benefits, integration, and other issues. Some items are of less concern, including cost, standards, and security, perhaps reflecting the maturity of the industry.

Research limitations/implications

This study was limited to a relatively small sample of WERC members but should continue to be replicated in the future as RFID technology adoption matures.

Practical implications

For RFID to be widely adopted by manufacturers and other firms upstream in the supply chain, they must be convinced of a better ROI, through cost reduction or improved business processes.

Originality/value

RFID is not hype and continues to mature. Few companies expected a positive ROI from the technology. These experiences and opinions should be of interest to those researching or considering RFID adoption.

Abstract

Purpose

The purpose of this paper is to investigate the value relevance of segment information for both public and private sector banks in India. In doing so, this paper examines a rapidly developing economy and perhaps its most critical sector during this period of strong economic growth.

Design/methodology/approach

In this study uses the simplified Ohlson model, for a sample of 136 private sector and public sector banks for the period 2007-2010 in India.

Findings

The paper finds that public sector banks have higher share prices, higher earnings and more equity compared with private sector banks. Segment earnings data is highly value relevant for both sectors; however, segment equity data is only marginally value relevant for Indian banks. The number of segments is also value relevant and associated with higher share prices.

Originality/value

The results of this study contribute additional evidence to the literature on segment reporting by studying the effect of adoption of segment reporting in an emerging market. Findings from the paper are particularly relevant as India is currently in the process of changing its segment reporting requirements and moving to an IFRS-based segment standard.

Abstract

This chapter has been seminal work of Dr K.S.S. Iyer, which has taken time to develop, for over the last 56 years to be presented here. The method in advance predictive analytics has developed, from his several other applications, in predictive modeling by using the stochastic point process technique. In the chapter on advance predictive analytics, Dr Iyer is collecting his approaches and generalizing it in this chapter. In this chapter, two of the techniques of stochastic point process known as Product Density and Random point process used in modelling problems in High energy particles and cancer, are redefined to suit problems currently in demand in IoT and customer equity in marketing (Iyer, Patil, & Chetlapalli, 2014b). This formulation arises from these techniques being used in different fields like energy requirement in Internet of Things (IoT) devices, growth of cancer cells, cosmic rays’ study, to customer equity and many more approaches.

Abstract

Purpose

The purpose of this paper is to examine citizens’ perception of police in India, particularly the authors examine the factors influencing citizen satisfaction with the police in India.

Design/methodology/approach

Using survey data collected from the residents in a neighborhood of the capital city and from the passengers on a 41-hour-1,281 miles journey traveling from the northern part to the southern part of the country and return via Indian Railways, this study empirically analyzed citizens’ perceptions of police and factors that accounted for the variation in Indian citizens’ assessment of police. Consistent with the literature, this study integrates a broader range of explanatory variables to explain citizens’ perceptions toward police, including demographic characteristics, views about professionalism in police, police performance, fairness, police corruption, and citizens’ perceptions about their safety in their neighborhood.

Findings

Older citizens reported higher satisfaction with the police. Among the contextual characteristics, the authors find a positive relationship between perceived police performance, fairness, professionalism, and citizen satisfaction with police. As expected, perceived police deviance is associated with lower citizen satisfaction with police.

Practical implications

Findings of the study provide Indian police administrators with important references and directions to improve police performance and move to increase citizen satisfaction about police. It also adds to the limited literature on citizens’ perceptions of the police in India.

Originality/value

This study is an attempt to systematically assess the citizens’ perception of police in India. The researchers believe that this as an original contribution in the body of criminal justice research, particularly to the scholarship on policing in India. Moreover, the examination of citizens’ satisfaction of police highlights their detailed views about professionalism of police, police performance, corruption, fairness and their perceptions about the safety in their neighborhood.

Abstract

Purpose

The purpose of this paper is to examine the degree of persistence of firm performance for publicly listed firms in Indonesia. The study also explores the impact of marketing expenditure on firm’s performance.

Design/methodology/approach

The data comprise 165 listed firms operating in Indonesia over the period 2007–2016. Dynamic panel regression estimations using Arellano and Bond (1991) and Blundell and Bond (1998) techniques have been deployed to generate the results.

Findings

The findings show the existence of positive persistence and sub-optimal level of competition in the performance of Indonesian firms. The results highlight that marketing intensity has a positive and significant impact on firm performance. The positive persistence hints at creation of substantial entry and exit barriers by the Indonesian firms and also indicate that Indonesian firms are able to create behavioral inertia among their consumers by properly directing their marketing efforts.

Practical implications

There is a need on the part of management to strengthen the short-term profit capabilities to nurture long-term benefits of profit maximization. On the regulators part, the authorities should frame the policies to foster long-run competition.

Originality/value

The current study contributes to the sparse literature on persistence of firm performance in the context of emerging economies like Indonesia. This is the first study on persistence of firm performance for publicly listed firms in Indonesia.

Abstract

Purpose

Product failures can lead to customer dissatisfaction, negative brand attitudes and a loss of brand equity. The purpose of this paper is to investigate whether extended warranties offer a mechanism to mitigate the negative effects of product failure and the mediating role of positive and negative self-directed emotions.

Design/methodology/approach

The hypotheses are tested using two 2 × 2 between-subjects experiments with product failure and warranty purchase as the two factors, attitude toward the brand as the dependent variable, positive and negative self-directed emotions as mediating variables and attitude toward warranties as a covariate.

Findings

It is found that the decline in attitude toward the brand due to product failure is greater among customers purchasing an extended warranty, than among those who do not. Moreover, positive and negative self-directed emotions mediate this relationship.

Originality/value

Manufacturers are for the most part not involved in distribution or administration of extended warranties, which are mainly sold through retailers and administered by companies that specialize in extended warranties. The study findings indicate that contrary to industry practice, consumer-durable manufacturers should consider more active management and promotion of extended warranties to protect their brand’s equity from the negative effects of product failure.

Abstract

Purpose

The purpose of this paper is to review Lean Six Sigma (LSS) literature and report different definitions, demographics, methodologies and industries.

Design/methodology/approach

This paper highlights various definitions by different researchers and practitioners. A total of 235 research papers has been reviewed for the LSS theme, research methodology adopted, type of industry, author profile, country of research and year of publication.

Findings

From the review, four significant LSS classifications were identified that deal with the spread of LSS in different industries followed by observation for classification.

Practical implications

LSS is a strategy for success, but it did not examine its presence in various Industries. From this paper, readers can understand the quantum of its spread before implementing LSS. For academicians, it will be a comprehensive list of papers for research.

Originality/value

This paper reviews 235 research papers for their year, author profile, research methodology and type of industry. Various characteristics of LSS definitions and their theme are also reviewed.
