Hollingsworth prefers the Solow growth accounting equation to calculate potential GDP growth rather than the more simplistic labor productivity growth accounting equation.
Exhibit 2 Long-Term Growth Projections
Based on the data in Exhibit 2, the GDP growth rate in Country A using Hollingsworth’s preferred method of calculation is closest to:
选项：
A.2.74%. B.2.94%. C.2.86%.解释：
Hollingsworth’s preferred method of calculating the GDP growth rate is the Solow growth accounting equation, and the rate is calculated as follows:
ΔY/Y = ΔA/A + α(ΔK/K) + (1 – α)(ΔL/L)
where
ΔY/Y = Growth in gross domestic product, GDP
ΔA/A = Growth in total factor productivity = 1/5%
ΔK/K = Growth rate of capital = 3.2%
ΔL/L = Growth rate of labor = 0.4%
α = Output elasticity of capital = 0.3
1 – α = Output elasticity of labor = 0.7
Thus, ΔY/Y = 1.5 + (0.3 × 3.2) + (0.7 × 0.4) = 1.5 + 0.96 + 0.28 = 2.74
首选的GDP增长率计算方法是索洛增长方程，其计算公式如下:
Δy / y = Δa / a + α(Δk / k) + (1 - α)(Δl / l)
其中
ΔY/Y =国内生产总值(GDP)增长
ΔA/A =全要素生产率增长= 1/5%
ΔK/K =资本增长率= 3.2%
ΔL/L =劳动力增长率= 0.4%
α =资本的产出弹性= 0.3
1 - α =劳动产出弹性= 0.7
因此,ΔY / Y = 1.5 +(0.3×3.2)+(0.7×0.4)= 1.5 + 0.96 + 0.28 = 2.74
