Methodology: Intro • hi = b0 + b1 gi + errori, where: hi = ΔH, and H is ave happiness of country gi = ΔY, and Y is log income of country • using h as dependent variable implies no happiness adaptation
Methodology: Intro • H = f(Y – AY) where AY is adaptation level • ΔH = f(ΔY – ΔAY) • Define AY = aY-1 + (1 – a)AY-1 … where a represents the rate of adaptation • Rearranging, ΔAY = a(Y-1 – AY-1)… • Substituting… ΔH = ΔY – a(Y-1 – AY-1) • ΔH = f(ΔY – aH-1) • Or, H = ΔY + (1 – a)H-1
Methodology: Intro • ΔH = f(ΔY) • hi = b0 + b1 gi + errori, where: hi = ΔH, and H is ave happiness of country gi = ΔY, and Y is log income of country
Methodology: Dynamic • hit = a0 + Σbj gi,t-j + Σdk-1 hi,t-k + errorit • where: j = 0…p lags k = 1…q lags • autoregressive distributed lag model with p lags on economic growth and q lags on happiness on the assumption that current and past information on both economic growth and happiness are relevant.
Methodology: Multilevel • hit = a0 + Σbj gi,t-j + Σdk-1 hi,t-k + errorit a0 = φ00 + u0t • where: φ00 is b/w country-averages across time u0t is the b/w country-averages variation • hit = φ00 + Σbj gi,t-j + Σdk-1 hi,t-k + (u0t + errorit)
Results • Sum (dynamic) = 0.005, p < 0.01 0.0038 LR • Sum (multilevel) = 0.004, p < 0.05 0.0032LR
Analysis • A unit of (LR) economic growth has 0.003 impact on happiness • If ave. long-run growth rate is 1.95, then 0.003 x 1.95 = 0.00585 • Suppose ave. happiness is 3.0 in a 4 unit scale. • To raise ave. happiness to 3.1, then 0.1 / 0.00585 = 17.09 years.
Conclusion • Reject the Easterlin Paradox based on the statistical significanceof results(i.e.that is, there is indeed positive income-happiness relationship) • Accept the Easterlin Paradox based on the economic non-significance of results. The estimates can be taken as a refutation of the Easterlin Paradox if they have econo-mic meaning.
