  1. The Ecological Economics ofCanada’s Ageing Population Eric Miller emiller@h4x.ca Presented Nov 1, 2013 at York University Canadian Society for Ecological Economics Conference

  2. A Conceptual Ecological Economic Demographic Model We should seek to model the means to an efficient, just, and sustainable Canada: • ime Demographics helps to deepen our understanding of life expectancy, the characteristics and size of the population, and demographic patterns of affluence (Inspired by NEF, 2012)

  3. An Empirical Model for Canada

  4. Current patterns as model inputs (StatCan, 2012) Average Life Expectancy at birth:M = 78.6yrs, F = 82.7yrs Lifetime Fertility Rate = 1.678 Total emigrants = 52,409 Total immigrants = 258,290

  5. Possible futures as assumptions (StatCan, 2010)

  6. Results of Canadian demographic scenarios Scenarios: 1=Low, 2=Med, 3=High, 4=Stabilization

  7. The Hypothesis of Apocalyptic Demography “Today, there are 4.2 working-aged Canadians for every senior citizen, making contributions to cover retirees' pensions and health care. By 2031, that ratio will be cut in half. The tax base will shrink, growth will slow and labour shortages will become even more dire...”

  8. Demographic (age-based) dependency Medium growth scenario

  9. Labour market dependency Medium growth scenario

  10. What about unpaid work?

  11. Effects of population growth on dependency __154=Value in 1971___________________________________________ __89=Value in 1971____________________________________________ Growth scenarios: 1 = Low, 2 = Medium based on trend of last 20 years, 3 = High Stabilization: 4 = Medium trend with balanced migration, 5 = Same with “delayed retirement”

  12. Understanding the dynamics of Canadian housing • Demographics  Household formation & dissolution • Macro-economics  Rates of change in household formation • Affluence  Demand for number of dwellings, and value • Financial system  Cost of financing, risk tolerance of lenders • Expectations of capital gains  Willingness to inflate prices • Cohort norms  Value of strategic locations Results impact the stock of residential dwellings and market value their land

  13. An empirical Canadian housing model

  14. Dynamics of residential land value 1=Actual total Res Capital Stock 2=Actual Res structures 3=Actual Res land Modelled values: 4=Predicted Res structures 5=Predicted Res land $M CAD

  15. Dynamics of investment in residential structures 1=Actual rate of gross investment in Res Capital Stock 2=Modelled rate (of #1) 3=Modelled rate of invest from renovations to existing structures; 4=Other 5=Modelled rate of investment from new structures AnnualRate

  16. Speculating about future housing dynamics (all scenarios assume 2010 patterns of household headship rates) Growth scenarios: 1 = Low, 2 = Medium based on trend of last 20 years, 3 = High Stabilization: 4 = Medium trend with balanced migration, 5 = Same with “delayed retirement”

  17. Concluding messages • Demographics should play an important role in EE • Beware of apocalyptic demography in Canada as a new rationale for austerity and growth for the sake of growth • Systems dynamics modelling useful for modelling residential housing market (structures and land value) • Understanding housing will help to understand an important component of life satisfaction during working years and into retirement, and the future ecological implications of growth in households, dwellings per household, and value per dwelling
