  1. Imputing Consumption – Concepts and Simplified Example Gretchen Donehower Day 3, Session 1, NTA Time Use and Gender Workshop Wednesday, May 23, 2012 Institute for Labor, Science and Social Affairs (ILSSA) Hanoi, Vietnam

  2. Outline • Review production • Concepts involved in imputing consumption • Consumption estimation strategy • Imputation assumptions • Work through spreadsheet example of simplified time use dataset (computing production and consumption)

  3. Production Review • See summary document on wiki

  4. Consumption Estimation Strategy • A Time Use Survey is: • A sample of time producers and types of activities they produce • A Time Use Survey is NOT: • A sample of all time produced in a household • A sample of time consumers and what they consumed • So what do we do to estimate consumption? • Impute consumption to producer’s household members and the general population by age and sex • Multiply by number of producers in the population by age and sex to get aggregate age-sex matrix • Divide by number of consumers to get consumption profile by age and sex

  5. Consumption Imputation Assumptions • For care activities • If care is for household members, divide equally among all household members in target age range • Example: for care of household children aged 0-18, divide time equally among all household members age 0-18 • If care is for non-household members, divide equally among general population in target age range • Example: for volunteering, divide time equally among total population • For general household activities • Divide equally among all household members

  6. Lab Session • Finish time production age profiles in time units and money units • Be ready to share some plots at the end of the session • Work through simplified spreadsheet example of consumption • If there is time, start thinking about how to implement consumption calculation strategy with your time use data
