Abstract
Purpose
The current pilot study explored food insecurity, food waste, food related behaviours and cooking confidence of UK consumers following the COVID-19 lockdown.
Design/methodology/approach
Data were collected from 473 UK-based consumers (63% female) in March 2020. A cross-sectional online survey measured variables including food insecurity prevalence, self-reported food waste, food management behaviours, confidence and frequency of use of a range of cooking methods, type of food eaten (ultra-processed, semi-finished, unprocessed) and packaging type foods are purchased in.
Findings
39% of participants have experienced some food insecurity in the last 12 months. Being younger, having a greater BMI and living in a smaller household were associated with food insecurity. Green leaves, carrots, potatoes and sliced bread are the most wasted of purchased foods. Polenta, green leaves and white rice are the most wasted cooked foods. Food secure participants reported wasting a smaller percentage of purchased and cooked foods compared to food insecure participants. Overall, participants were most confident about boiling, microwaving and stir-frying and least confident with using a pressure cooker or sous vide. Food secure participants were more confident with boiling, stir-frying, grilling and roasting than insecure food participants.
Practical implications
This has implications for post lockdown policy, including food policies and guidance for public-facing communications.
Originality/value
We identified novel differences in self-report food waste behaviours and cooking confidence between the food secure and insecure consumers and observed demographics associated with food insecurity.

Abstract
Purpose
Brazil is characterized by the inexistence of a more robust system of guarantees and rules to minimize risks and protect agents in energy futures contracts. In this sense, this study aims to answer the question of how a centralized clearing agent can compute safety margin requirements to help reduce the systemic risk of the energy futures contracts market in Brazil.
Design/methodology/approach
The intermediate steps and specific objectives are to analyze the volatility behavior, identify the autoregressive conditional heteroscedasticity effects and model the variance of the return series. Based on this, the authors calculate the value-at-risk and conditional value-at-risk metrics for the energy futures contracts. As a robustness test, the authors added a peak over threshold methodology from extreme values theory.
Findings
In general, monthly products require margins because of their higher variance. With the asymmetrical distribution of returns, the authors needed to consider different maintenance margins for the long and short positions. It was also shown that two guarantee margins were required to secure the contracts as follows: the initial margin and the maintenance margin. The three factors that defined the size of the maintenance margin the volatility, skewness and kurtosis of the return series.
Originality/value
The contribution of this study lies in promoting the understanding of the risk dimensions of the energy derivatives market in Brazil and it offers concrete recommendations for how to mitigate this risk through market mechanisms and structures. Similar arrangements can be applied to other emerging markets.

Abstract
Purpose
This study aimed to identify the potential for economic activities related to the ocean economy in Brazil to become blue economy (BE) activities, in which the concept of the Sustainable Development Goals (SDGs) is central.
Design/methodology/approach
To achieve the aim, the authors collected information on the SDGs and estimated data from the ocean economy sectors for the 256 Brazilian coastal cities. The authors predicted the indices for potential development of territories and sectors in the BE using two parameters: employed persons (EP) and sectoral added value (AV).
Findings
The results show that the capitals of coastal states present the highest potential indices for the BE, especially Rio de Janeiro, which accounted for 83.3% of sectoral added value in the Brazilian ocean economy with potential for sustainable development and generated 107,800 active formal jobs (26.9% of the country's total). In addition, restaurants, hotels and similar establishments are, on the Brazilian coast, the most frequent on the coastal zone and have the highest potential for BE activities.
Originality/value
Regarding its contributions, this research innovates by developing an indicator that can help stakeholders understand the similarities and differences between cities and regions, whether through a social, economic, or environmental lens. Therefore, by following this methodological path for measuring the BE, viewing the distinct patterns of sustainable development by area is possible, thereby supporting action plans for the fulfillment of the 2030 Agenda and the implementation of a marine spatial planning process for the country in the context of the Ocean Decade (2021–2030).

Abstract
Purpose
This study aims to assess suppliers’ learning from knowledge transfers with a global truck manufacturer, considering both source and supplier capacity, and the cultural proximity between the parties.
Design/methodology/approach
A case study was conducted between two factories, one in Brazil and one in Germany. This study adopted a mixed-method sequential explanatory approach, which involves a quantitative phase followed by a qualitative one to provide a better understanding of the studied phenomenon. Quantitative data were collected from the automaker’s suppliers in both countries and analyzed using factor and inferential analyses. Qualitative data were obtained from the automaker’s purchasing executives, and from the company’s suppliers in both countries. Content analysis was used to analyze data.
Findings
Results suggest that both the source’s disseminative capacity and suppliers’ absorptive capacity had a positive effect on suppliers’ learning during knowledge transfers. The study also found out that cultural proximity among parties positively moderates the relationship between suppliers’ absorptive capacity and their learning. However, cultural proximity does not moderate the relationship between a source’s disseminative capacity and supplier learning.
Practical implications
This study’s findings are important to foster knowledge transfers by developing absorptive and disseminative capabilities in the automakers industry, in which the implementation of interorganizational learning is quite challenging due to the large number of strategic providers.
Originality/value
This study contributes to theoretical and conceptual consolidation of knowledge transfer, which includes cultural proximity among parties and the source’s and supplier’s disseminative and absorptive capacities, respectively. This study constructs and validates a model of knowledge transfer using a large automaker with a worldwide presence.

Abstract
Tourism and crime are closely related phenomena, and security is one of the basic preconditions for the functioning of tourism since tourists and tourist areas have many characteristics that make them vulnerable to crime. In this chapter are presented the actual (objective) risk of crime and tourists victimization, visible in statistics on committed crimes and crime victims surveys, and the perceived (subjective) risk of crime, recorded in surveys conducted with tourists. The characteristics which influence the actual and perceived risk of crime and violence are presented by analysing three key elements in the relationship between tourism and crime: (1) tourist (these characteristics are classified as socio-demographic, socio-cultural and psychological); (2) trip (characteristics are the purpose of the trip, travel party, and stage of the trip); and (3) destination (characteristics are crime rates in destination, the occurrence of crime by place and time, type of accommodation and length of stay).

Abstract
Purpose
The purpose of this paper is to study the case of Chile and identify the internal factors that lead to senior (+55 years old) entrepreneurship, either by necessity or opportunity, compared to that in other age groups.
Design/methodology/approach
The analysis is based on the adult population survey of the global entrepreneurship monitor between 2012 and 2016 and uses a logistic regression model that applies different variables to total early-stage entrepreneurial activity by necessity and opportunity.
Findings
Education, human and social capital development, gender and prior experience as an entrepreneur are internal factors that affect entrepreneurial activity with different weights and directions for people over 55 years old in Chile, either by necessity or opportunity. Further, certain factors exhibited by other age groups in the country explain entrepreneurship.
Research limitations/implications
This study does not consider external perspectives on how context influences entrepreneurial intentions.
Practical implications
This paper represents a first step to understanding the factors that governments should consider when designing policies to support entrepreneurial activity in the senior demographic sector, considering differences in motivation by necessity or opportunity. In addition, this study contributes to the development of knowledge regarding senior entrepreneurship in Chile and to the identification of best practices that could be used in other regions.
Originality/value
This report is the first to focus on the motivations of senior entrepreneurs in Chile by quantifying the effects of different factors.

Abstract
Speculative bubbles have been occurring periodically in local or global real-estate markets and are considered a potential cause of economic crises. In this context, the detection of explosive behaviors in the financial market and the implementation of early warning diagnosis tests are of critical importance. The recent increase in Brazilian housing prices has risen concerns that the Brazilian economy may have a speculative housing bubble. In the present chapter, we employ a recently proposed recursive unit root test in order to identify possible speculative bubbles in data from the Brazilian residential real-estate market. The empirical results show evidence for speculative price bubbles both in Rio de Janeiro and São Paulo, the two main Brazilian cities.

Abstract
Purpose
The purpose of this meta-analytic study is to investigate the possible influence of food shape abnormality on consumer’s willingness to buy fruits and vegetables. This research also investigates some possible moderators (methodological, cultural, socio-economic and contextual) that could influence the direct effects.
Design/methodology/approach
This study applied the meta-analysis approach to understand the effect of food shape abnormality on willingness to buy fruits and vegetables. In this research, 16 empirical articles were examined, with a total of 54 effect sizes.
Findings
The results showed consistent negative effects between food shape abnormality and consumers’ willingness to buy fruits and vegetables. This study also found significant effects related to culture (Hofstede’s cultural dimensions) and to socio-economic (Human Development Index) moderators. The findings demonstrated that cultures with higher power distance levels promoted stronger effects in the relationship between abnormally shaped food and willingness to buy. Additionally, related to social–economy aspects of a nation, the negative effects between abnormally shaped food and willingness to buy are stronger in countries with low human development rates.
Practical implications
Public policymakers can benefit from the main findings by implementing interventions strategies and education campaigns based on different cultural dimensions. In cultures characterized by high levels of aversion to uncertainty, social communication campaigns can build trust and provide the consumer more knowledge about abnormally shaped fruits and vegetables, whereas in cultures characterized by low levels of masculinity, related to higher levels of sustainability, local producers can benefit from the “local food” positioning to sell abnormally shaped fruits and vegetables.
Originality/value
This research advances studies about consumer behaviour in relation to food waste, highlighting factors beyond aesthetic issues, such as a nation’s culture and its economic context. These results open the way for new work in this area.

Abstract
Purpose
This study aims at understanding how consumers engage with and perceive value in “spectacular” versus “spontaneous” designs of tourist experiences. Building on the idea that experiences unfold over time through consumers' interactions with multiple touchpoints composed of assemblages of material and interpersonal elements, how these designs can be conducive to various dimensions of the consumer experience value is shown.
Design/methodology/approach
A qualitative comparative “embedded case study” (Yin, 2018) of the tourist experiences at In Vino (pseudonym), a traditional winery located in the Vale dos Vinhedos (Valley of the Vineyards) in southern Brazil, was conducted. Based on initial archival research into relevant and noteworthy experiences, two distinct tourist experiences for In Vino were designed. Both experiences were implemented, and participant observations and interviews with participants were conducted.
Findings
The two experiences effectively lead visitors to unique and separate interpersonal, temporal and materially engaging experiences. Both generated educational, entertainment, esthetic and escapist value when well executed, and the comparative analysis by the authors helped in outlining a potential combination of the characteristics of spectacular and spontaneous designs that can enhance authenticity value for tourists.
Practical implications
This study provides practical information to help companies develop positive consumer experiences in tourism by employing different combinations of temporal, material and interpersonal elements to emphasize different types of value. It also suggests guidelines for what to do and what to avoid in order to create this value.
Originality/value
This paper shows that it is the very union of elements from two apparently antagonistic types of encounters that provides positive values in tourism-related experiences. It also extends the notion of authenticity as an outcome that can potentially be perceived in both types of experiences. Finally, it introduces guidelines on how to manage the different values in order to help companies offer a positive tourist experience.
