Exogenous brand crises: brand infection and contamination

Marketing Letters - Although there is an established literature regarding brand transgressions, Covid-19 has highlighted the need to better understand exogenously created brand crises. We...     

Intellectual capital reporting practices in an Islamic bank: A case study

Given the nature and importance of Islamic banks in recent times, we can expect them to have significant intellectual capital anchored in their Sharia‐based knowledge and expertise. However, we know very little or nothing about how and why intellectual capital‐related information is provided in their corporate reports. We fill this gap in our existing knowledge of the field with a view to enhance relevant literature. As far as we know, this article is one of the earliest exploratory attempts to examine intellectual capital reporting practices of an Islamic bank. We have undertaken a longitudinal (2001–2015) case study related to the intellectual capital reporting practices of an Islamic bank. Key results include significant rise of intellectual capital reporting over time, dominance of internal capital‐related items in intellectual capital reporting profile and the dynamics of changes in intellectual capital reporting practices over time. Through an institutional theory lens, we explain that this is due to the changes in the external institutional environment and various intra‐organisational factors such as strong ethical culture, unique knowledge base (Sharia), and corporate governance regime.     

CKshare: secured cloud-based knowledge-sharing blockchain for injection mold redesign

This paper proposes a trustable mold redesign knowledge-sharing platform, known as CKshare, based on private cloud and blockchain technology. Firstly, we use private cloud to store the mold redesign knowledge of each party to meet its own privacy and data format requirements. Secondly, a blockchain network is used for recording the knowledge and its transactions to ensure security and trustfulness. Thirdly, a simple retrieval mechanism is developed based on k-nearest neighbors for retrieving the codified knowledge on the platform. To realize CKshare, a prototype platform has been developed and explained based on real data from the case mold company.     

Catastrophe futures and reinsurance contracts: An incomplete markets approach

We present a theoretical methodology for the pricing of catastrophe (CAT) derivatives with event‐dependent and non‐convex payoffs given the price of a CAT indexed futures contract. We do not assume a fully diversifiable CAT event risk, nor do we assume knowledge of the martingale probability measure beyond the futures price. We derive tight bounds on the contract value and present trading strategies exploiting the mispricing whenever the bounds are violated. We estimate the bounds of the reinsurance contract with data from hurricane landings in Florida. Our method is also applicable when there is no futures market but the price of a CAT‐indexed bond is available.     

The effect of the dynamics of knowledge base complexity on Schumpeterian patterns of innovation: the upstream petroleum industry

This article analyzes important changes in technological innovation in the upstream petroleum industry. It provides evidence that shifts in sectoral patterns of innovation over the petroleum industry's lifecycle from the 1970s up to 2005 were dependent on the dynamics of knowledge base complexity (KBC), a key dimension of an industry's technological regime. Accordingly, observed shifts in innovation patterns are understood to be the aggregated strategic response of industry innovators to changes in the technological regime. The article proposes a quantitative method for exploring KBC and Schumpeterian patterns of innovation, and interactions between the two at the industry level. As the industry evolved, its knowledge base moved to higher orders of complexity creating a shift in the Schumpeterian pattern of innovation. Increased KBC was found to alter Schumpeterian patterns from Mark I toward a ‘modified’ Mark II. Instead of coming predominantly from ‘traditional’ established oil operators, technological innovation was increasingly triggered by a new class of emergent integrated service companies – ‘second tier’ systems integrators of the upstream sector able to cope with increased KBC.     

Institutional stakeholdings and better-informed traders at earnings announcements

Utama and Cready [Utama, S., Cready, W.M., 1997. Institutional ownership, differential predisclosure precision and trading volume at announcement dates. Journal of Accounting and Economics 24, 129–150] use total institutional ownership to proxy for the proportion of better-informed traders, an important determinant of trading around earnings announcements. We argue that institutions holding small stakes cannot justify the fixed cost of developing private predisclosure information. Also, institutions with large stakes generally do not trade around earnings announcements since they are dedicated investors or face regulations that make informed trading difficult. However, institutions holding medium stakes have incentives to develop private predisclosure information and trade on it; we show that their ownership is a finer proxy for the proportion of better-informed traders at earnings announcements.     

Attitude toward business environment of auditing,corporate governance and balance between auditing and marketing

The aim of this study was to evaluate the attitude of Iranian auditors toward balance between auditing and marketing with respect to two important components of audit process such as business environment of auditing and corporate governance. The analysis is based on survey data from 257 respondents. To achieve the research aims, we specified four hypotheses based on social theories. The results of this study show that the auditors having positive attitude toward marketing and those who consider it as significant are able, to a large extent, balance spent time for inherent auditing tasks and marketing activities. In addition, the results show that an increase by a unit for the attitude toward business environment results in 0.489 unit increase in attitude toward balance of time spent on marketing and auditing activities, of which 0.396 is direct impact and 0.093 is indirect impact.     

Public Revenue‐Expenditure Nexus in South Africa: Are there Asymmetries?

This paper re‐examines the government revenue and expenditure relationship in South Africa using Enders and Siklos' Threshold adjustment and Granger causality tests. The paper allows for structural breaks in the unit root and cointegration tests. The results indicate the absence of any asymmetries in both the threshold autoregression and momentum threshold autoregression specifications of adjustments in the South African's budgeting process. The estimated symmetric error‐correction models provide support for the fiscal synchronization hypothesis of government revenues and expenditures for long‐run and short‐run dynamic equilibrium. These findings indicate that the South African fiscal authorities should try to maintain or even improve the control of their fiscal policy instruments to sustain the prudent budgetary process.     

Countercyclical Bank Capital Requirement and Optimized Monetary Policy Rules

Using BoC-GEM-Fin, a large-scale dynamic stochastic general equilibrium (DSGE) model with real, nominal, and financial frictions featuring a banking sector, we explore the macroeconomic implications of various types of countercyclical bank capital regulations. Results suggest that countercyclical capital requirements have a significant stabilizing effect on key macroeconomic variables, but mostly after financial shocks. Moreover, the bank capital regulatory policy and monetary policy interact, and this interaction is contingent on the type of shocks that drive the economic cycle. Finally, we analyze loss functions based on macroeconomic and financial variables to arrive at an optimal countercyclical regulatory policy in a class of simple implementable Taylor-type rules. Compared to bank capital regulatory policy, monetary policy is able to stabilize the economy more efficiently after real shocks. On the other hand, financial shocks require the regulator to be more aggressive in loosening/tightening capital requirements for banks, even as monetary policy works to counter the deviations of inflation from the target.
