Torrens’s view on main conclusions in Rosell’s reconstruction indicate economic dynamics can be explicitly explained by the the following: Torrens’s approach to distribution growth model, which incorporates the wage satisfying considers that the wage rate is set as a result of dynamic equilibrium between the growth rates of competition among capitalists or among workers, population and of capital, the minimum wage fixed exogenously and the maximum wage depending on the fertility of the lands under cultivation.

Such a long-term analysis is not involved in ‘the maximum of wages’ is defined as ‘that quantity of Rosell’s model, in which the system is assumed to be the products of industry which remains, after replacing limited to a single period.

Section 2 amount of ‘maximum wages’ received by 100 workers introduces Torrens’s concept of wages, based on (200 quarters) is the amount of output (428 quarters) which Torrens’s model of economic growth is set up in minus the amount of non-wages fund (200 quarters) Section 3.

The maximum wage rate depends on the following The real level of ‘actual wages’2 is determined by three circumstances: ‘the quality of the soil, the skill ‘the ratio between population and capital, or, more with which labour is applied, and the degree of correctly, between the quantity of labour and the freedom which is allowed to trade’ (p. 462).
