Fear Linkages Between the US and BRICS Stock Markets: A Frequency-Domain Causality

Abstract

We employ a spectral causality approach to uncover short-, medium-, and long-run causal relations between the US implied volatility index and the five individual implied volatility indexes of BRICS markets from 16^th March 2011 to 31^st January 2018. We show that the volatility causal relations differ between the short and long run in many cases. Although the results indicate the dominant role played by US uncertainty in shaping uncertainty in all BRICS markets, there is also evidence of a feedback effect from Brazil, Russia, and China to the US that differs across the spectrum. The implications for hedging and risk management practices are explored.     

Regional and copula estimation effects on EU and US energy equity portfolios

ABSTRACT

The aim of this paper is to investigate the regional interdependence structure of energy equities in the US and in the EU. Based on weekly stock prices of 28 big energy firms in the two regions from 2008 to 2019, we compare the efficiency of using bivariate or multivariate copulas to describe the dependence structure of energy equities. Furthermore, we investigate the impact of the choice between these two methods on the performance of energy equity portfolios. Our empirical results show that multivariate copulas, such as C-Vine, allow to better describe the dependence structure of energy equities. We also find that there is a stronger and more complex dependence structure among EU energy equities than among US energy equities. Our scenario analysis also shows that the dependence structure is stronger during the GFC while being weaker during the ESDC. More importantly, the correlation matrix obtained from the multivariate copula method allows to obtain optimal mean-CVaR portfolios with a higher performance than that from the bivariate copula method. More importantly, optimal portfolios constituted with multivariate copulas allow to reduce the portfolio’s sensitivity to oil prices.     

From ‘Publish or Perish’ to Societal Impact: Organizational Repurposing Towards Responsible Innovation through Creating a Medical Platform

Why would an academic project incentivized towards scientific publications be repurposed to become a medical platform for responsible innovation? Patient Innovation, a non-profit medical platform that focuses on the sharing and dissemination of innovations to find solutions for rare and chronic diseases, was initially set up as an academic research project. However, team members reframed their core purpose from conducting research on user innovation to providing global access to these innovations and creating societal impact. Using a framing lens to understand organizational repurposing, we illuminate how serendipitous inspiration, moral emotions and the power of socially conscious users and catalysts drove this emergent reframing of core purpose and develop a model of organizational repurposing. We show how a frame drift towards a change in purpose occurs spontaneously in interactions, as actors frame and reframe situations and feel inspired and morally motivated to transcend their immediate self-interests and serve collective goals.

Management controls in family-owned businesses (FOBs): A case study of an Indonesian family-owned University

This paper reports on the results of a case study of management controls in an Indonesian family-owned University. The paper attempts to understand the nature and dynamics of management controls in the operations of the University. Data for the analyses are gathered from multiple sources including document analysis, observations and semi-structured interviews. The findings of the case study showed that culture and social relations are very instrumental in the management of the University [Ansari, S. L., & Bell, J. (1991). Symbolism, collectivism and rationality in organizational control. Accounting, Auditing and Accountability Journal, 4(2), 4–27]. Decisions such as recruitment, rewards, performance evaluation, and resource allocations are often made in cognizance of social and cultural factors. The strong influence of culture and social relations in the organization thus made formal management controls less relevant. These findings have implications for understanding management controls in FOBs especially in the developing world.     

A macroeconometric framework for monetary policy evaluation: A case study of Pakistan

This paper attempts to establish the quantitative importance of the various channels of monetary transmission by constructing, estimating and simulating a small macroeconometric model of Pakistan's monetary sector, while using data from the monetary statistics and the monetary survey of the State Bank of Pakistan over 1976–2007. The paper elucidates that the key feature of the study of monetary policy in Pakistan has been preoccupied with neglect either of the demand or the supply function of money and shows how this may lead to imprecise policy actions and mistaken conclusions. Accordingly, we delineate the transmission mechanism of monetary policy by taking into consideration all structural money demand and money supply linkages along with the historically implied identifying assumption in the framework of a marginalized macroeconometric model. The within-sample and out-of-sample evaluations of the model are found satisfactory. The paper presents results of three policy simulations from the estimated model that highlight the impact of alternative monetary policy instruments on the monetary variables under a rule-based and a discretionary policy environment. We find that (i) the SBP subscribes to an unannounced monetary policy rule, (ii) the determination of the policy rate under the announced rule environment stabilizes the monetary sector in that convergence to full equilibrium is smooth and rapid, (iii) a 100 bps reduction in the discount rate, ceteris paribus, decreases money supply by 4.97%, and (iv) the long term implication of reducing (increasing) the reserve requirement ratio on time (demand) deposits, ceteris paribus, is only higher inflation. Finally, we establish that a 100 bps increase in interest rate increases money supply by 3.14% in full equilibrium.     

Stock returns and macro risks: Evidence from Finland

Deviations from the CAPM have generally been observed for the stock markets. One of many alternative approaches is using macro variables as systematic risks. We tested with a number of macro risks for the explanation of Finnish industry returns for a period from 1993:03 until 2008:07. The evidence suggests macro risks explain larger cross-sectional variations in average industry returns than the market factor alone and same is reported with the Hansen and Jagannathan (1997) specification measure. The changes in expected returns with a positive shock in the exchange rate risk and unanticipated inflation remain economically persistent for the post euro period, arguably a sign for the regulatory impact of the coordinated policies from European central bank (ECB). The robustness checks show the prevalence of macro risks, and market risk cannot be ignored altogether.     

Maintenance of Cross-Sector Partnerships: The Role of Frames in Sustained Collaboration

The finance industry is required to respond to public criticism of perceived immoral behaviour. To create legitimacy, financial firms not only undertake corporate social responsibility (CSR) activities, but also support such activities with precise justifications. In this paper, we study CSR justifications appearing in annual and sustainability reports from the Swedish finance industry. Our objective is to investigate the ethical character of CSR justifications in the finance industry. This is an interesting topic, both because CSR carries ethical meaning and because CSR justifications play a role in actual business activities. A secondary aim of this article is to test whether decoupled corporate claims about CSR can be recoupled, which would potentially help companies to act responsibly. The observed CSR justifications avoided the fundamental question of whether the finance industry does in fact have responsibilities, and they did not manifest awareness of stakeholders’ demands for CSR. Seemingly value-based CSR activities often lacked ethical justifications. These characteristics do not harmonize with the responsible image that the contemporary finance industry wants to portray. Our counterintuitive finding is that amorality prevails in the justifications that banks give for undertaking CSR activities.     

Does Shariah compliance make interest rate sensitivity of Islamic equities lower? An industry level analysis under different market states

This paper examines the sensitivity of the Dow Jones Islamic market index and its corresponding industry equity indices to changes in the level, slope and curvature of the U.S. term structure of interest rates over the period 1996–2015 using the quantile regression approach. The empirical results reveal that the Islamic stock market has a considerable negative exposure to interest rate risk, although a declining time pattern of interest rate sensitivity is observed. The unexpected changes in the level factor of the U.S. yield curve, closely linked to long-term interest rates, are identified as the most important interest rate factor in explaining the variability of Islamic equity returns. Furthermore, the interest rate exposure tends to be stronger during extreme bearish conditions in the stock market, possibly due to the greater pessimism and risk aversion under these market circumstances. It is also shown that Islamic equities are not different from their mainstream counterparts in terms of interest rate sensitivity, indicating that the Islamic stock market does not provide a cushion against interest rate risk.
