摘要：There is a common perception that it costs more to eat a healthy diet than a less healthy one. Wederive a panel data model that accounts for unobserved specific individual effects to estimate therelationship between diet quality and total daily food expenditure. Since total daily diet cost anddiet quality are both calculated from the foods chosen in our data, we account for the fact thatthere is an endogenous relationship between diet quality and cost. We find that while total dailyfood expenditure is statistically significant in relation to diet quality, the degree of association isvery small.
