Exhibit 1Long-Term Tren of ltoniEconomy A.G growth is primarily iven labor. B.ltonia’s economy is performing a stea state rate of growth. C.Output per worker is falling. The components of growth ctermineusing Solow’s growth accounting equation: ΔY/Y = ΔA/A + αΔK/K + (1 − α)ΔL/LTFP = Labor proctivity growth – Growth in capitepening = 1.7 – 2.3 = –0.6, whiis given in Exhibit 1. Also given, 1 – α = 0.65 anα = 0.35 生长的成分可以用索洛生长核算方程来确定:ΔY/Y = ΔA/A + αΔK/K +(1−α)ΔL/LTFP =劳动生产率增长-资本深化增长= 1.7 - 2.3 = - 0.6，如图1所示。还给出了1 - α = 0.65和α = 0.35具体计算过程请参考上表。 这是之前上课讲的公式△y/y=△T/T + capitepening%本题需要计算△y/y=△T/T + α(△k/k)那么capitepening%就是α(△k/k)吗？我看另外的一个解答中说capitepening%指(△k/k)，如果是这样，那怎么计算TFP结果不用乘以α？

Also given, 1 – α = 0.65 anα = 0.35 上课说，不能用人口增长率来代替（看到老师之前的解答，说这一题有瑕疵）那么，可不可以算出growth rate of labor呢？已知%Δy=1.7%，%ΔT=-0.6%，根据y=T（K/L)^α，得到%Δy=%ΔT+α%Δ（K/L)，α=0.35，算出%Δ（K/L)=6.57%K/L=K➗L，得到%Δ（K/L)=%ΔK-%ΔL，%ΔK=6.1%，算出%ΔL=-0.47%。这种思路对吗？
