The traditional predictor of technical inefficiency proposed by Jondrow, Lovell, Materov, and Schmidt (1982) is a conditional expectation. This chapter explores whether, and by how much, the predictor can be improved by using auxiliary information in the conditioning set. It considers two types of stochastic frontier models. The first type is a panel data model where composed errors from past and future time periods contain information about contemporaneous technical inefficiency. The second type is when the stochastic frontier model is augmented by input ratio equations in which allocative inefficiency is correlated with technical inefficiency. Compared to the standard kernel-smoothing estimator, a newer estimator based on a local linear random forest helps mitigate the curse of dimensionality when the conditioning set is large. Besides numerous simulations, there is an illustrative empirical example.

Source credibility is a key influencing factor across both commercial and social marketing. It is perhaps even more important for the latter given that the issues under consideration generally have substantial implications for both individual and societal health and well-being. The Act-Belong-Commit campaign is a world-first population-wide application of social marketing in the area of positive mental health promotion. This study aims to focus on the perceived credibility of the Act-Belong-Commit campaign as a source of information about mental health as a predictor of three types of behavioural responses to the campaign: adopting mental health enhancing behaviours; seeking information about mental health and mental health problems; and seeking help for a mental health problem.

A state-wide survey was undertaken of the adult population in an Australian state where the Act-Belong-Commit campaign originated. The survey included measures of the above three behavioural responses to the campaign and measures of respondents’ perceptions of Act-Belong-Commit’s source credibility. Logistic regression analyses were performed to determine whether the three behavioural responses can be predicted based on perceived source credibility. The predictive performance of the model was examined by receiver operating characteristic curve analysis.

Greater perceived source credibility was significantly associated with having done something for their mental health and for having sought information, and an increased likelihood, but not significantly so, of having sought help for a mental health problem.

Despite the acknowledged importance of source credibility, there has been little published research that the authors are aware of that has looked at the impact of such on the effectiveness of social marketing campaigns. To the best of the authors’ knowledge, this is the first published study of the association between source credibility and behavioural response to a social marketing campaign.

This chapter provides an introduction to the world of family companies and family constitutions from a legal perspective. It first studies the legal types of business organizations that family firms have chosen across time and jurisdictions. It then illustrates how early predecessors of family constitutions evolved in the late Middle Ages and what modern family constitutions look like in different countries today. Further considerations are devoted to the governance framework of family firms. The chapter concludes by exploring the potential legal effects of family constitutions under German company and contract law.

The application of circular economy (CE) has received wide coverage in the built environment, including public-private partnership (PPP) infrastructure projects, in recent times. However, current studies and practical implementation of CE are largely associated with construction demolition, waste and recycling management. Few studies exist on circular models and success factors of public infrastructures developed within the PPP contracts. Thus, the main objective of this article is to identify the models and key success factors associated with CE implementation in PPP infrastructure projects.

A systematic review of the literature was undertaken in this study using forty-two (42) peer-reviewed journal articles from Scopus, Web of Science, Google Scholar and PubMed.

The results show that environmental factors, sustainable economic growth, effective stakeholder management, sufficient funding, utilization of low-carbon materials, effective supply chain and procurement strategies facilitate the implementation of CE in PPP infrastructure projects. Key CE business models are centered around the extension of project life cycle value, circular inputs and recycling and reuse of projects.

Although the study presents relevant findings and gaps for further investigations, it has a limited sample size of 42 papers, which is expected to increase as CE gain more prominence in PPP infrastructure management in future.

The findings are relevant for decision-making by PPP practitioners to attain the social, economic and environmental benefits of transitioning to circular infrastructure management.

This study contributes to articulating the key models and measures toward sustainable CE in public infrastructure development.

Improving a startup’s ability to obtain funding is critical to the survival of the organization. Although existing studies have observed various biases in investment decisions, few have studied the neural mechanisms behind such behavioral observations. We propose to apply cutting-edge neuroscientific techniques to uncover the neural processes engaged during pitches by entrepreneurs to investors and to use this new knowledge to identify strategy artifacts promoting pitch success. We hypothesize that pitches are dynamically shaped by covert cognitive, emotional, and social processes, which are in turn influenced by tactical approach (story-telling vs dry facts), physical context (online vs in-person), and demographics (gender, ethnicity). The role of inter-brain synchrony (i.e., correlation of cortical activity between brains) – within the startup team or between the entrepreneurs and investors – in pitch outcomes remains unknown. By uncovering the covert processes that mediate pitch outcomes, we provide an evidence-based, scientific approach to improving pitch success.

The study aims to estimate the short- and long-run effects of monetary policy on residential property prices in South Africa. Over the past decades, there has been a monetary policy shift, from targeting money supply and exchange rate to inflation. The shifts have affected residential property market dynamics.

The Johansen cointegration approach was used to estimate the effects of changes in monetary policy proxies on residential property prices using quarterly data from 1980 to 2022.

Mortgage finance and economic growth have a significant positive long-run effect on residential property prices. The consumer price index, the inflation targeting framework, interest rates and exchange rates have a significant negative long-run effect on residential property prices. The Granger causality test has depicted that exchange rate significantly influences residential property prices in the short run, and interest rates, inflation targeting framework, gross domestic product, money supply consumer price index and exchange rate can quickly return to equilibrium when they are in disequilibrium.

There are limited arguments whether the inflation targeting monetary policy framework in South Africa has prevented residential property market boom and bust scenarios. The study has found that the implementation of inflation targeting framework has successfully reduced booms in residential property prices in South Africa.

This secondary source case is based mainly on legislative documents (that tracked the initiation and progress of the Parental Rights in Education bill that later became an Act), corporate documents (published by The Walt Disney Company) and news articles from publications such as The New York Times and Bloomberg. All sources are cited in the case narrative and as end notes.

In April 2022, The Walt Disney Company and its CEO, Robert Chapek, were at the center of a controversy over the company’s opposition to the State of Florida’s Parental Rights in Education bill. The bill, dubbed “Don’t Say Gay” by its critics, prohibited instruction on sexual identity and gender orientation in the state’s elementary schools. The controversy stemmed from Disney’s initial non-reaction to the bill and its later strident opposition and call for its repeal. Chapek was pressured by negative media publicity and employee disgruntlement on the one hand and adverse economic consequences for opposing the bill by the state’s Governor, Ron DeSantis. Chapek and the Board had to respond to the political threats to Disney’s economic well-being while appeasing its employees and other stakeholders who wanted the company to be a corporate champion in diversity, equity and inclusion.

The case is best suited for advanced undergraduate or graduate leadership, strategic management and marketing courses. From a leadership and strategic management perspective, the case is well-suited for demonstrating the evolving expectations of leaders and corporate social responsibility, as well as the concepts of issue framing and nonmarket management. Instructors may also leverage the case in marketing courses (e.g. brand management), as CEO activism (i.e. messaging and practice) is one characteristic of brand activism (Animation Guild, 2022).
