Тема доклада: "A new year, a new you? Heterogeneity and self-control in food purchases"
Тезисы доклада: We document that within-person (over time) variation in diet qualityis large and characterized by a steady decline over the calendar year. Wedevelop a two-selves model that provides a structural interpretation to thisvariation, in which food choices are a compromise between a healthy and anunhealthy self. We show that the data are consistent with this model usingrevealed preference methods. Around 25% of within-person fluctuations indiet quality are explained by variation in prices, budgets, advertising andweather conditions. The residual fluctuations are larger for individuals withlower stated self-control, lower income and younger people.
