Let us consider a Solow growth model in which the aggregate production function
at time t for country i is given by:
Yit =Ai(Kit)1-βi(ei Lit) βi
Where Yit is the aggregate real GDP in country i, Kit is the aggregate physical capital in country i, Lit is the aggregate number of workers in country i, ei is the average working time of a worker parameter in country i, Ai >0 is the total factor productivity parameter in country i and βi ∈ (0,1) is the labor share of output parameter in the country i. The equilibrium law of motions of the physical capita per worker from time t to time t+1 in country i can be written as:
(1+ni) kit+1=yi yit +(1- ?i) Kit
where ?i ∈ (−1, +∞) represents the growth rate of the population of workers parameter in country i, ?i ∈ (0,1) denotes the investment rate parameter in country i, ?i ∈ (0,1) is the depreciation rate parameter in country i and ?it denotes the output per worker in country i.
