Magic numbers Let yo be the GDP per capita at year 0,y the GDP per capita at year T,and x the average annual growth rate over that period Then, y=(1+x)T yo Taking logs,we compute lny灯-lnyo=Tln(1+x)≈Tx, or equivalently x=(In yr-In yo )/T

Magic numbers  Let y0 be the GDP per capita at year 0, yT the GDP per capita at year T , and x the average annual growth rate over that period. Then, yT = (1+ x ) T y0  Taking logs, we compute ln yT - ln y0 = T ln(1+ x) ≈T x, or equivalently x = (ln yT - ln y0 )/T . Chyi, Macro I, 2006

Magic numbers For example: 1.US per-capita GDP,1995 prices ·$3300in1870 grew by a factor≈I0 "$32500in2000 →average growth rate: g=[ln(32500)-ln(3300)]/130=1.75%. 2.China with a annual rate as high as 10%, which accumulates to a factor of 17.45 over the 30-year period

Magic numbers  For example: 1. US per-capita GDP, 1995 prices $3300 in 1870 $32500 in 2000 average growth rate: g = [ln(32500)-ln(3300)]/130=1.75%. 2. China with a annual rate as high as 10%, which accumulates to a factor of 17.45 over the 30-year period. grew by a factor ≈ 10 Chyi, Macro I, 2006
