The aim of this study is to adopt a multifactor model to investigate the dynamic impacts of changes in the Reserve Bank of Australia’s (RBA) cash rate on the equity returns of the largest Australian companies during the period from January 1998 to May 2024.

The general-to-specific modeling strategy is used to determine how equity returns respond to contemporaneous or lagged changes in market movements, oil prices and calendar anomalies. The estimated parsimonious models pass key diagnostic tests, revealing that changes in the cash rate influence most companies, albeit in different directions and with varying response times.

While most banks, mining and insurance stocks are heavily impacted by changes in the cash rate, health and oil and gas stocks are predominantly affected by systemic market movements and oil prices. Almost all (13 out of 15) stocks exhibit significant responses to changes in oil prices.

Understanding these differential effects can help investors optimize their portfolio rebalancing strategies, particularly during periods of anticipated changes in interest rates. This is especially timely as the RBA is expected to start cutting the cash rate in the foreseeable future.

This study provides new insights by examining how changes in cash rates and oil prices impact the stock returns of Australia’s largest companies. It offers investors practical strategies for adjusting their portfolios in response to fluctuations in interest rates, oil prices and calendar anomalies.

Wine has been produced for thousands of years and nowadays we have seen a spread in the wine culture. E-commerce sales of wine have increased considerably and online customer's satisfaction is influenced by quality and price. This paper presents a case study of the company “QuieroVinos, S.L.”, an online wine shop founded in 2015 that sells Spanish wines in two main marketplaces.

With the final target of increasing the company profits it has been designed and developed an application to track the prices of competitors for a set of products. This information will be used to set the product prices in order to offer the products both competitively and profitably in each Marketplace. This application must check, by tacking into account information such as the product cost or the minimum product margin, if it is possible to decrease the price in order to reach the top cheapest position and as a consequence, increase the sales.

The application improved in a notorious way the company's results in terms of sales and shipping costs. It must be said that without the use of the presented application, performing the price comparison process within each one of the marketplaces would have taken a long time. Moreover, as prices change very frequently, the obtained information has a very limited time value, and the competitors prices should be analyzed daily in order to take accurate decisions regarding the company's price policy.

Although the application has been designed for the wine sector and the two named marketplace, it could be exported to other sectors. For that, it should be implemented new modules to collect information regarding the competitor's price of the products selling on each corresponding marketplace.

Organization and management scholars are increasingly interested in understanding how “fluid” forms of organizing contribute to the tackling of grand challenges. These forms are fluid in that they bring together a dynamic range of actors with diverse purposes, expertise, and interests in a temporary and nonbinding way. Fluid forms of organizing enable flexible participation. Yet, they struggle to gain and sustain commitment. In this case study of the SDG2 Advocacy Hub, which supports the achievement of zero hunger by 2030, we explore how the temporality of narratives contributes to actors’ commitment to tackling grand challenges in fluid forms of organizing. In our analysis, we identify three types of narratives – universal, situated, and bridging – and discern their different temporal horizons and temporal directions. In doing so, our study sheds light on the contributions by the temporality of narratives to fostering commitment to tackling grand challenges in fluid forms of organizing. It suggests the importance of considering “multitemporality,” i.e., the plurality of connected temporalities, rather than foregrounding either the present or the future.
