Several authors refer to product portfolio management as an essential process because it may be used as a corporate management tool. However, the product portfolio management methods which are often adopted have limitations that prevent its use in practice, mainly due to the high dimensionality of selecting an optimal portfolio. Moreover, the large amount of available data is a relevant issue for practical applications. Thus, the contribution of this article is to propose a method for the product life cycle to monitor time-series behaviour patterns. The goal is to identify changes that may indicate that the product portfolio needs to be revised. The proposed method uses a multivariate regression model to relate financial variables associated with the products portfolio, the performance of products against competition, and even macroeconomic data. The objective is, through profile monitoring, to identify the specific time for the product portfolio review decision-making. We adopted three tools to develop a method -- principal component analysis, multivariate regression model, and profile monitoring with Hotelling T² Control chart. A Monte Carlo simulation validated the approach. The results showed false alarm rate and average time to signal to be similar to previous studies. Finally, the application of the model is illustrated in a real case, using data provided by a company's portfolio of agricultural equipment. [ABSTRACT FROM AUTHOR]

Packing constitutes the majority of solid wastes produced, especially in the case of food. Current research verifies by descriptive analysis the intention of purchasing food wrapped in sustainable packages, whether the sustainability issue is foregrounded on biodegradable packages, or on recycling or on the application of reverse logistics. Preliminary results show that trend is specially underscored in the case of young women with high education level. Purchase intention decreases in all groups when sustainable package features costs above market prices, with an average 10% tolerance in price rise. Firms' investment in sustainability causes positive impacts on consumers' purchase decision, especially on people under 50 years. [ABSTRACT FROM AUTHOR]

Research on behavioral motivation for green product consumption has greatly advanced in recent years, but many unknowns remain, particularly regarding consumers' willingness to pay premium prices for products with ecological appeal. In this context, this paper reports an experimental research that investigates the relationship between consumer perceived value for green products and price elasticity. The research was performed using an adaptation of the model proposed by Zeithaml (1988) and it was applied in the automotive and furniture sectors. It was found that perceived value of green products increases willingness to pay in the purchasing decision. It was also observed that demographical variables, such as gender, age and revenue positively impact perceived quality and the consequent purchase intention. Considering the population sampled, results indicate that the effect of ecological appeal is similar to a 10% price reduction. It means that, according to the declared preference, respondents were willing to pay, on average, a 10% premium for green products in the studied product categories. The main theoretical contribution of our paper lies in furthering the understanding of how key dimensions that constitute perceived value relate to each other and to demographic and personal influence variables, as well as its impact in willingness to pay premium prices for green products.
