问题如下：
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
题目中的GDP增长率没有加potential，那这题是不是算的实际增长率？用公式算出来的是potential GDP增长率，算实际的GDP增长率是不是还要减去通胀率？
