The impact of oil prices and the financial market on cost efficiency in the insurance and Takaful sectors: Evidence from a stochastic frontier analysis

The Gulf Cooperation Council’s (GCC) insurance industry, including conventional insurance and Takaful, has witnessed remarkable growth during the last decade. However, the economies of this region rely on oil as the primary stream of revenue and lack development in financial markets. This could affect the insurance industry. For this reason, this paper examines the impact of oil prices and the financial market on the cost efficiency of the insurance and Takaful sectors in GCC countries using a stochastic frontier cost function with data from 2009–2016. The results show that the relationship between oil prices and efficiency changes from positive to negative when the prices increase, whereas the relationship between the financial market and efficiency is negative. No clear evidence of the impact of oil prices on efficiency arises from the differences between conventional insurance and Takaful. However, there are differences regarding the financial market, with a negative impact on conventional insurance and a positive one on the Takaful business. The results of this study have implications for regulators and management. The Takaful industry is rapidly growing compared to conventional insurance in the GCC and, therefore, the financial market may have added benefits for the GCC region. However, caution is required in relation to the impact of the financial market on conventional insurance. Furthermore, management may require the development of strategies to deal with the nature of GCC economies to avoid shocks to oil prices.     

Does Green Public Procurement lead to Life Cycle Costing (LCC) adoption?

Life Cycle Costing (LCC) is rarely used in public procurement and public institutions have yet to fully understand its potential value for sustainable procurement. The new European Directive on Public Procurement is, however, designed to position LCC as central to sustainable sourcing. Although previous studies have identified positive correlations between Green Public Procurement Policies (GPP) and LCC, it is still unclear how public institutions can further adopt LCC practices by leveraging their experience of green sourcing. In this study an organizational learning theoretical perspective is taken to investigate the circumstances under which public administrations’ experience of GPP – considered as a way of integrating the dimension of environmental sustainability into the sourcing process – stimulates their LCC learning and capabilities – considered as a way to include the sustainability economic dimension. The goal is to understand if the adoption of GPP can stimulate the internalisation of LCC in public tenders. A multinomial logistic regression was conducted using a sample of 120 public administrations located in different countries. The results show that experience of GPP stimulates the internalisation of LCC at a public level, but only under specific conditions. The study contributes to the Sustainable Supply Management literature, being one of the first studies in the field adopting an organizational learning theoretical lens to review the role of experience as significant opportunity to develop capabilities. It also contributes to the organizational learning theory, by confirming that experience can aid learning but only in specific environmental contexts.
