1. Following the line of Prof. Domar's model of economic growth, we wish to reconstruct a two-sector model of balanced growth. We define the relevant variables : V is the investment in the capital goods industry. W is the investment in the consumption goods industry. λ is the ratio of the increment in output to the investment in the capital goods industry. μ is the ratio of the increment in output to the investment in the consumption goods industry. α is the marginal propensity to save. Then, for the balanced growth to be maintained, the economy have to satisfy[numerical formula]From these we have[numerical formula]where k = 1/α-1. 2. But, starting with the process of balanced growth, the investment decision in the real competitive process, I submit, may tend to result in (ΔV)/V>(μλ)/(μ+kλ) (ΔW)/W>(μλ)/(μ+kλ). These two equations mean that the economy is in the course of the so-called boom.
