An implicit association test (IAT) was used to investigate how habit strength, implicit attitudes and fruit consumption interrelate. Fifty-two participants completed a computerized IAT and provided measures of fruit consumption and related habit strength. Implicit attitudes moderated the habit strength—fruit consumption relationship; stronger relationships were observed when implicit attitudes were more positive. Amongst those with strong fruit habits, more positive associations with fruit were found for those who had recently consumed sufficient fruits compared to those who had not. Findings demonstrate the relevance of implicit positive associations in understanding the relationship between fruit consumption habits and subsequent fruit consumption.

Outward habit formation affects consumption decisions. Since consumption displays a negative environmental externality, outward habits has as well an (adverse) effect on the environment. This research paper centers around the theoretical linkage between the combination of both externalities (environmental deterioration and outward habits). The objective of this study is to examine the impacts of outward habits on the state of the environment in the context of an overlapping generations economy. In our study, environmental quality is a public good negatively affected by consumption activity and positively affected by maintenance investment. With outward habit formation, the build-up level of average past consumption in the economy at large influences the current utility of an individual consumer. Thus, individuals draw utility not only from their own level of current consumption, but also from its level relative to the average consumption in the economy. How does outward habit influence the state of the environment? We analyze this question using an overlapping generations model with outward habit and environmental quality in the utility function. In steady state equilibrium allocation, we show that whether outward habits are destructive to the environment depends on the degrees of outward habit formation and the size of the economy.
