David Ricardo ([1817] 1965) modified Smith’s model by introducing diminishing returns to land cultivation. Diminishing returns implies that as you apply more of a variable input (labor) to a fixed input (land), the productivity of each additional worker will eventually decline as long as technology isfixed. He claimed that land was of variable quality and finite. Thus, as an economy grows, population grows relative to land, and the productivity of the labor on the land will decline. According to Ricardo, the only way stagnation could be averted, at least temporarily, would be through the trade and imports of cheap food or wage goods. The essential doctrines of John Stuart Mill (1848) differed little, if at all, from those of Ricardo. He, like Smith, believed in the doctrine of laissez-faire , but he also recognized the possibility of modifying the system. He displayed a leaning to the socialist ideal, growing closer as his life advanced. He believed that we should sacrifice economic…

Neoclassical Production Function Please write the production function in its simplest form (human capital being included in TFP) and explain the nature of each factor of production.
Suppose that output is given by the neoclassical production function Y (t) = F (K(t), L(t), A(t)) satisfying Assumptions 1 and 2, and that we observe output, capital, and labor at two dates t and t + T . Suppose that we estimate TFP growth between these two dates using the equation Where g(t, t + T ) denotes output growth between dates t and t + T , and other growth terms are defined similarly, while αK(t) and αL(t) denote the factor shares at the beginning date. Let x(t, t + T ) be the true TFP growth between these two dates. Show that there exist functions F such that x(t, t ˆ + T )/x(t, t + T ) can be arbitrarily large or small. Next show the same result when the TFP estimate is constructed using the end-date factor shares: Explain the importance of differences in factor proportions (capital-labor ratio) between the beginning and end dates in these results.
The Black Death: (a) Wages were higher after the Black Death because of diminishing returns. Our production model exhibits diminishing returns to labor: each additional unit of labor increases output by less and less. So if the amount of labor is reduced, the marginal product of labor — and hence the wage — increases. The reason is that capital stays the same: each remaining worker is able to work with more machines, so his productivity rises. In fourteenth-century Europe, the marginal workers could move to better land and discard old broken-down tools. Graphically, this can be seen by considering the supply-and-demand diagram for labor in Figure 4.2(b). If the supply of labor shifts back (because a large number of workers die), the equilibrium wage rate increases. Draw this graph — including the shift in the labor supply curve — to see the result for yourself. Mathematically, the result can be seen in the solution for the wage rate in our production model,…
