Unleashing proactive low-carbon strategies through behavioral factors in biodiversity-intensive sustainable supply chains: Mixed methodology

The aim of this research is to understand the complex and relatively understudied relationship between human and behavioral factors and low-carbon management practices from the perspective of the resource-based view (RBV). Research application is in the “biodiversity sector” and consists of a survey and multiple-case study in Brazil, the richest country globally in terms of biodiversity but a country that also faces challenges in protecting biodiversity. The research problem considers the relationship between human critical success factors and the adoption of low-carbon management practices. Quantitative analysis through structural equation modeling shows the three branches of hypothesis to be accepted—the first with a higher coefficient than the second and the second with a higher coefficient than the third. It was observed that human factors influence low-carbon product management practices the most, followed by process practices and finally logistics practices. Qualitative multiple-case study research shows that companies are at different stages of maturity in relation to low-carbon management organizational practices, ranging from the highest stage to the lowest. It was found that the intensity of the presence of human critical success factors was higher where organizations had greater adoption of low-carbon management practices.     

Australia's National Electricity Market after Twenty Years

The Hilmer reforms served electricity consumers well over the first post-reform decade. However, three key issues emerged from the mid-2000s: (i) a significant and largely unnecessary rise in network expenditures; (ii) emissions policy discontinuity; and (iii) a large increase in wholesale prices due to rising fuel prices and the sudden exit of generators. The consequence was a doubling in retail prices. Deficiencies in cost-recovery mechanisms have meant price increases have disproportionately affected low-income households. We propose three key reforms as rectification: (i) integrating emissions reduction and energy policies; (ii) boosting network capacity utilisation; and (iii) improving cost recovery mechanisms.     

Performance of Personal Pension Funds in Portugal

This paper analyses the performance of personal pension funds in Portugal, during the period from 1999 to 2016, providing the first detailed analysis of this matter. Three performance measures are used: the Sharpe ratio, the difference between the returns of the fund and its benchmark, and the M² measure. The findings show that the performance of these funds is very low and that their returns are not significantly different from zero, which might be the result of government-imposed limits concerning asset allocation. Additionally, evidence was found confirming that these funds, on average, underperform their benchmarks. Tax gains seem to be the main reason why people decide to invest a portion of their wealth in these funds, rather than in other investment forms where there are no penalties in the case of early withdrawals.
