Changing defaults—the preselection that becomes effective without active choice—is becoming a prominent policy tool, after having been proven to be effective in areas as varied as retirement savings, organ donation and product customization. Yet, little is known about how default effects spill over to subsequent similar behaviors. In an online shopping scenario, we found standard default effects on the share of organically produced products in the overall selection of products. These effects did not spill over to subsequent active shopping choices. This was true for defaults that were hard and easy to change (Exp. 1, N = 90), for immediate and delayed subsequent choices (Exp. 2, N = 106) and for self‐selected defaults (Exp. 3, N = 181). These findings suggest that the reach and scalability of default manipulations in policy making may be limited, but also speak against the possibility for negative spillover.

High and sustained economic growth rates of the Ghanaian economy in the past two to three decades have been accompanied by a growing urban middle class. With a rapidly growing middle class, overall consumption is not only increasing but changing too. This paper analyses the asset ownership patterns among the Ghanaian middle class, and examines the effect of household wealth, environmental concern and environmental knowledge on carbon dioxide emissions emanating from energy use and transport based on urban household survey data collected in Accra, the capital city, in 2018. We find that middle class households consume a variety of energy intensive consumer goods, and the intensity of consumption increases with household wealth. Regression results reveal statistically significant relationship between household wealth and carbon emissions from energy and transport use. We also find that environmental knowledge has a statistically negative effect on carbon emissions from transport. The policy implications are discussed.
