Notes: This table shows the evidence on calories and expenditure changes. The omitted category is the year before diagnosis, not including the month before. In Columns (1), (5) and (6) the independent variables are timing interacted with the probability of being diabetic, as inferred from the machine learning approach. These coefficients can be interpreted as the impact of diagnosis. In Columns (2) and (3) the independent variables are timing alone, and the sample is either the overall sample, or limited to households with higher predicted probability. Standard errors are in parentheses. The figures in square brackets in Columns (2) and (3) show the estimated impact scaled up to 100% diagnosis. This should be comparable with the coefficient in Column (1). Regressions include controls for household fixed effects and year-month fixed effects. Magnet households are those who also scan and report prices for non-UPC coded goods
