Behind the ‘creative destruction’ of human diets: An analysis of the structure and market dynamics of the ultra-processed food manufacturing industry and implications for public health

A global transition towards diets increasingly dominated by ultra-processed foods (UPFs) has occurred in recent decades to the detriment of public health and the environment. This study aimed to examine long-term trends in the structure and market dynamics of the global UPF manufacturing industry as part of broader efforts to understand the drivers of this transition. Using diverse methods, metrics and data sources, we examined several dimensions (e.g., industry concentration and profitability) according to an adapted structure–conduct–performance model. We found that the global UPF manufacturing industry has evolved to become a major component of global food systems, with its longstanding dominant corporations becoming some of the system's largest accumulators of profit and distributors of capital. It follows that reversing the global UPF dietary transition will require structural and regulatory changes to ensure that population diets, and food systems more broadly, are not subordinated to the interests of powerful for-profit business corporations.

Do risk and competition trigger conditional cooperation? Evidence from public good experiments

We investigate the effect of intra-group competition and risk marginal per capita returns on subjects' cooperative behavior in a one-shot public good game—following the well-known approach proposed by Fischbacher, Gächter, and Fehr (2001) and extending the Colasante et al. (2018, 2019) parametrization. We study the interaction between environment and social preferences and test the existence of a causal relationship of risk and competition over cooperative behavior when an individual's benefit of the public good is heterogeneous and uncertain. Our results report experimental evidence about competition fostering cooperative behavior leading to a rise in contribution for all the subjects regardless of their social preferences. However, risk has a detrimental effect on cooperative behavior due to encouraging free riding.     

Ebb and flow: Structural and spatial change in Victoria's brewing industry, 1870–1900

The brewing industry has undergone profound structural and spatial change over the last 150 years. We examine how consolidation began in Victoria's brewing industry using a historical GIS approach. We argue that industry restructuring was shaped by four interlocking dynamics between 1870 and 1900: (1) structural economic change; (2) railway development; (3) technological innovation; and (4) regulatory reform. We show that the ebb and flow of these interacting dynamics generated a non-linear process of change. Similar to North America and Europe, the industry became highly concentrated. However, this process was complicated by local factors such as climate, economy, and distance.     

Dynamics of contention in the gig economy: Rage against the platform,customer or state?

Protest in the gig economy has taken many forms and targets (platforms, customers and state officials). However, researchers are yet to adequately account for this diversity. We use a European survey of Upwork and PeoplePerHour platform workers to investigate worker orientation towards different forms of protest. Results reveal that worker anger, dependence and digital communication shape contention in the remote gig economy. Support for collective organisation is associated with anger at platforms as well as their dependence on the platform and communication with other workers. Individual action against clients is associated with anger and communication but not dependence. Support for state regulation is associated only with anger but not dependence or communication. We conclude that the relational approach entailed by Mobilisation Theory can aid explanation in the gig economy by shedding light on the dynamic process by which solidarity and dependence alter the perceived cost/benefits of particular remedies to injustice.     

The organization of volunteer battalions in Ukraine

When war broke out in Eastern Ukraine in 2014, the government of Ukraine failed to provide adequate defense to maintain its territorial integrity. In the wake of this government failure, several private volunteer efforts arose to meet popular demand for military action against Russian-backed Separatists. These volunteer battalions had to find alternative methods of aligning their incentives with the population wishing to be defended, and alternative methods of aligning the incentives of their leadership and their recruits. The success of these battalions depended on the potential for political careers and favors, the strength of reputation mechanisms in small communities, and the potential for loot and spoils. These factors shaped the size, characteristics, and activities of the volunteer battalions.

     

eWOM processing from receiver perspective: Conceptualising the relationships

Electronic word-of-mouth (eWOM) communication is considered an important source of information for consumers. In existing frameworks and empirical studies, factors that lead to eWOM influence have been categorised into three essential elements equivalent to the three elements of communication processing: source, receiver and message. eWOM requires a more elaborate form of information processing, given the many-to-many nature of such communications and that the types of information processing differ between novice and experienced consumers. However, there is no conceptualisation that demonstrates the relationships among the factors of eWOM from this critical information processing perspective. Further, there is limited discourse on the situation and communication channel, although the situation and platform characteristics shape the nature of communication in the digital age. This paper reports insights obtained from an extensive literature review and presents a broader categorisation encompassing the factors of source, receiver, message, situation, task involvement and channel. Research propositions and recommendations for further research into eWOM processing are offered.
