Abstract:
... Household food waste originates in three predictable stages – when shopping, storing, and serving. That is, food can be purchased and never prepared, prepared and never served, or served and never eaten. Building on behavioral economics insights, this framework focuses on why consumers waste food in these three stages and how marketers can help consumers reduce food waste and thereby help them get ...

Abstract:
... Food waste has become a global concern in recent years, especially the household food waste that is generated in the developed world. Multiple methods to measure household food waste have been proposed, but little is known about their validity. Five methods are selected and investigated empirically: survey questions about general food waste over a non-specified period of time, diaries, photo codin ...
