Traceability adoption at the farm level: An empirical analysis of the Portuguese pear industry

Traceability is becoming a condition to operate in European food markets. Retailers impose more stringent standards than what is mandatory. An example is EurepGAP, a quality standard for good agricultural practices that imposes traceability as a main obligation. This research investigates the choice of traceability at the farm level in the Portuguese pear industry. Results suggest that in this industry farm-level adoption of EurepGAP traceability is best explained by the choice to sell to the United Kingdom (UK). For farmers selling to the UK, the odds of choosing the EurepGAP traceability level are significantly linked to membership in particular producer organizations, farm productivity, producing products under a protected designation of origin (PDO), and farmer’s age. While retailers and farmer organizations seem to drive traceability, policy adjustments may be required to reduce adoption costs upstream and extend compliance among producers that sell directly to consumers and market independently.     

The Brazilian wage curve: new evidence from the National Household Survey

This paper reconsiders the Brazilian wage curve using individual data from the National Household Survey at 27 Federative Units over the period 2002–2009. We find evidence in favor of the Brazilian wage curve with an unemployment elasticity of ?0.08. We also find that males in Brazil are significantly more responsive to local unemployment rates (?0.13) than their female counterparts. In fact, we find that the unemployment elasticity for women is statistically insignificant. Applying gender-specific unemployment rates, the elasticity for men decreases to ?0.09, while the elasticity for women remains statistically insignificant. This paper also finds that the estimates for Brazilian wage curve are completely different for the case of formal and informal workers.     

Factors influencing hedging decision: evidence from Brazilian citrus growers

The purpose of this study was to analyse the hedging behaviour of 98 citrus growers from the State of Sao Paulo, Brazil. Marketing behaviour was modelled as a choice between spot market, short and long‐term forward contracts. A multinomial logistic regression model was used to evaluate the role of behavioural, personal and managerial variables in the choice. Results indicated that the factors which explain the use of forward contracts by citrus growers are the following: risk propensity; trade with juice processing companies; farming diversification; overconfidence in management; participation in pools; use of management tools; and technical assistance. The results can be useful for farmers, policymakers, government agencies, traders and extension agents.     

A bivariate infinitely divisible law for modeling the magnitude and duration of monotone periods of log‐returns

The focus of this article is modeling the magnitude and duration of monotone periods of log‐returns. For this, we propose a new bivariate law assuming that the probabilistic framework over the magnitude and duration is based on the joint distribution of (X,N), where N is geometric distributed and X is the sum of an identically distributed sequence of inverse‐Gaussian random variables independent of N. In this sense, X and N represent the magnitude and duration of the log‐returns, respectively, and the magnitude comes from an infinite mixture of inverse‐Gaussian distributions. This new model is named bivariate inverse‐Gaussian geometric ( in short) law. We provide statistical properties of the model and explore stochastic representations. In particular, we show that the is infinitely divisible, and with this, an induced Lévy process is proposed and studied in some detail. Estimation of the parameters is performed via maximum likelihood, and Fisher's information matrix is obtained. An empirical illustration to the log‐returns of Tyco International stock demonstrates the superior performance of the law compared to an existing model. We expect that the proposed law can be considered as a powerful tool in the modeling of log‐returns and other episodes analyses such as water resources management, risk assessment, and civil engineering projects.     

Environmental management systems: an alternative marketing strategy for sustainability

The purpose of the paper is to shed light on the extent to which environmental management systems such as ISO 14000 standards influence marketing efforts. By examining firms who prefer ISO 14000 standards against those who do not, this research provides a platform for understanding their significance when applied to marketing and seeks to improve environmental marketing strategies. The study empirically tests whether statistically significant differences exist between the two groups on a set of marketing variables. The study uses hierarchical clustering Ward’s method and measurement using squared Euclidean distances to determine the two groups. Discriminant analysis (DA) was used to classify each of the observations into selected groups; and test differences between these groups. Stepwise DA identified customer satisfaction as the best marketing predictor. This research indicates that green market-driven solutions for responsible consumption work best when it is consumer-driven, and consumers derive satisfaction from those results. The results adopts the view that investing in IS0 14000 standards is also highly beneficial for the wider applicability of developing strategies that would help firms make better decisions in marketing.     

Sociomateriality: Theories,methodology, and practice

This article aims to present the theoretical trends that constitute the notion of sociomateriality in the field of organizational studies and to describe a methodological framework for conducting empirical research in this field. It is a contribution for those interested in understanding and using the sociomateriality approach theoretically and methodologically. The main conclusion is that sociomateriality is a valuable alternative not only for comprehending how the entanglement of human and non-human actors may produce organizations, their practices, and changes, but also for (re)thinking organizational phenomena both ontologically and methodologically.
