 note = {Shopping is an essential activity for household management, and consumers make shopping decisions nearly every day. Although shopping is necessary for　consumers, there is limited information on how shopping is performed in a given　day and how the frequency of shopping is affected by consumption cost factors,　categorized as storage costs, travel costs, and opportunity cost of time. We examine the effects of storage costs, travel costs, and opportunity costs of time on consumers’ shopping decisions on a given day. Using anonymous micro data from the Survey on Time Use and Leisure Activity (STULA) conducted by the Statistics Bureau in 2001, we find that increases in storage costs and decreases in travel costs result in a greater probability of shopping. The other parameter estimates on consumer demographics are palatable in terms of opportunity costs of time and thus support our analysis.},
