Leapfrogging to Sustainable Consumption? An Explorative Survey of Consumption Habits and Orientations in Southern Brazil

In current political and scientific debates on sustainable consumption, the low- and middle-income classes of emerging countries are gaining attention. One common feature of such debates is the idea that these emerging consumer classes could be motivated to “leapfrog” directly to environmentally and socially aware consumption patterns and, thereby, avoid adopting the resource-intensive consumption styles of populations in industrialized countries. To be able to adapt sustainable product development or sustainable communication strategies to the needs of low- and medium-income classes, it is necessary to know more about the basic consumption orientations, current consumption habits, and future consumption aspirations of these societal groups. In order to contribute towards filling that knowledge gap, an exploratory survey was conducted, taking the example of emerging low- and middle-income classes in a Southern Brazilian city. The survey identified five different consumer types: the Home-Centered Traditionals, the Indifferent, the Up-to-date Privileged, the Wanna-be Materialists, and the Quality of Life-Oriented Postmaterialists. The paper outlines some ideas concerning how these types can be addressed with target-group-specific products and services as well as differentiated sustainability communication strategies. We conclude, however, that “leapfrogging” of Brazilian low- and middle-income classes towards sustainable consumption is not a very likely option. There are certain consumption orientations that sustainability strategies can link to, but these trends are not likely to compensate the general tendencies towards a resource-intensive lifestyle following the model of the industrialized countries.

Small business survival and inheritance: evidence from Germany

This paper investigates whether small businesses face financial constraints that affect their survival. A model of moral hazard is developed in which financial constraints arise endogenously. The model predicts that higher private assets relax financial constraints and have a positive effect on the firm’s probability of survival. The empirical analysis confirms that the entrepreneur has a higher propensity to stay in business when she inherits capital. This effect is particularly strong for entrepreneurs who switch from self-employment into wage employment.

A note on least squares estimation and the blue in a generalized linear regression model

In a generalized linear regression model, least squares and Gauss-Markov estimators differ, in general, if the variance-covariance matrix of the disturbances is singular. In the present note it is shown that, nevertheless, the conventional least squares procedure leads to a Gauss-Markov estimator if it is applied to a modified model which results from adding dummy constraints to the original model. These constraints reflect the effects of the singularity of the variance- convariance matrix. As a consequence, a Gauss-Markov estimate may always be obtained by standard least squares minimization, which offers considerable computational advantages.
