^ Orlando, Giuseppe Sportelli, Mario (2021), Orlando, Giuseppe Pisarchik, Alexander N.Once it crosses the u* line it will begin moving south-west. For example, the north-western region (high employment, low labor's share in output) the economy is moving north-east (employment is rising, worker's share is increasing).
The figure below indicates with arrows the movement of the economy in each region. The two lines defining the center of the cycle divide the positive orthant into four regions. While the model can be solved explicitly it is instructive to analyze the trajectory of the economy in terms of a phase diagram. Which determines the center of a family of cyclic trajectories. The amount of employed labour is given by Α is the rate of growth of labour productivity β is the rate of growth of the labour force γ is used to define the real wage change curve ρ is also used to define the real wage change curve σ is the capital-output ratio.Ī number of derived quantities are helpful to define the model. Which are all functions of time (although the time subscripts have been suppressed for convenience) and the constants Q is output k is (homogeneous) capital w is the wage rate a is labour productivity n is the labour force

real wages change according to a linearized Phillips curve, where wages rise when close to full employment.a fixed amount of output can always be turned into the same amount of capital) the capital-output ratio is constant (i.e.workers completely consume their wages, and capitalists completely invest their profits.there are only two factors of production: labour and capital.there is steady growth of the labour force (e.g.there is steady growth of labour productivity (e.g.The model is derived from the following assumptions:
