The Relationship

The study examines the contemporaneous relationship between Nifty returns and India VIX returns. Literature documents that the relationship between them is negative and asymmetric. Building on this, the study considers the linear and quadratic effect of stock index return (CNX Nifty) and examines the changes in implied volatility index (India VIX). The study finds both linear and quadratic CNX Nifty index returns are significant for changes in the level of India VIX. Findings suggest that India VIX provides insurance both for downside market movement and size of the downside movement.

AbstractWe study the relationship between patient choices and provider quality in a rehabilitation service for disabled patients who receive the service frequently but do not have access to quality information. Previous research has found a positive relationship between patient choices and provider quality in health services that patients typically do not have previous experience or use frequently. We contribute by examining choices of new patients and experienced patients who were either forced to switch or actively switched their provider. In the analysis, we combine register data on patients’ choices and switches with provider quality data from a competitive bidding, and estimate conditional logit choice models. The results show that all patients prefer high-quality providers within short distances. We find that the willingness to travel for quality is highest among new patients and active switchers. These results suggest that new patients and active switchers compare different alternatives more thoroughly, whereas forced switchers choose their new provider in limited time leading into poorer choices.

PurposeThis paper aims to provide a retrospective on the Journal of Derivatives and Quantitative Studies (JDQS) on its 30th anniversary based on a bibliometric analysis.Design/methodology/approachThe authors use the performance analysis to analyze patterns in JDQS's publications, citations and citation indices over the years. To investigate the relationship among keywords and authors, the authors of this paper employ science mapping by analyzing keyword-level networks and author-level networks using the KCI- Korean Journal Database of WOS. The authors use VOSviewer for bibliographic analysis and cluster analysis at the keyword and author levels. To study the effect of JDQS articles' attributes on citations of the articles, the authors conduct a regression analysis with KCI data. The authors regress the citations for each article on the article's attributes.FindingsJDQS's yearly publications, citations, impact factors and centrality indices grew in the early 2010s before diminishing in 2020. Keyword network analysis reveals that JDQS's main keywords include behavioral finance, implied volatility, information asymmetry, price discovery, KOSPI200 futures, volatility and KOSPI200 options. Citations of JDQS articles are mainly driven by article age, demeaned age squared, conference, nonacademic authors and language. Based on the number of views and downloads of JDQS articles, the authors find that recent changes in publisher and editorial and publishing policies have increased the journal's visibility.Originality/valueThis study quantitatively analyzed the bibliographic information of papers published in JDQS, a representative Korean academic journal in the finance area. This confirms the academic contribution of JDQS over the past 30 years and provides implications for future strategies of the journal. It shows the patterns in JDQS's publications, citations and citation indices and identifies the main authors and most cited papers. However, there is no such bibliometric analysis on Korean financial journals; thus, this study can contribute to the literature in this point.

Purpose Co-creation fosters customer’s involvement for innovation in products/services and is used as a tool to develop competitive edge for better entrepreneurship. Based on limited evidence, the study aims to examine the factors contributing to the co-creation and the relationship of co-creation with customer satisfaction. Design/methodology/approach A sample of 384 customers from selected banks in Pakistan was selected. The study adopted quantitative, explanatory and cross-sectional research design. Structural equation modeling is used for analysis. Findings The results revealed a positive and significant relationship between co-creation with customer satisfaction. Further results revealed that access to information, risk assessment and transparency have a positive relationship with co-creation for innovation. The study is significant for customers and management of banks to understand the implications of co-creation to increase customer satisfaction. Research limitations/implications Few banks with a small number of customers were selected for the study. Practical implications Managers must consider customer’s access to information, risk assessment and transparency of information as necessary factors for co-creation that foster innovation and entrepreneurial opportunities because co-creation strengthens customer satisfaction. Social implications Adopting the co-creation process brings long-lasting harmony between customers and banks, and customers may consider the banks as being socially responsible by inviting the opinions of their customers. Originality/value Model is re-tested in the context of Pakistani banks with selected variables affecting co-creation for innovation. Moreover, the relationship of co-creation with customer satisfaction is examined.
