The Rybczynski theorem was developed in 1955 by the Polish-born English economist Tadeusz Rybczynski (1923–1998). It states that at constant relative goods prices, a rise in the endowment of one factor will lead to a more than proportional expansion of the output in the sector which uses that factor intensively, and an absolute decline of the output of the other good.
The price elasticity of demand is a highly useful tool in managerial economics as it provides managers with the predicted change in demand associated with an increase in the price charged for its goods and services. [24] The price elasticity principle also outlines the changes in demand for goods with changes in the income of a populous. [24]
Since there is no increase in labor productivity in sector one, the output of sector one at time (denoted ) is: Y 1 t = a L 1 t {\displaystyle Y_{1t}=aL_{1t}} where L 1 t {\displaystyle L_{1t}} is the quantity of labor employed in sector one and a {\displaystyle a} is a constant that can be thought of as the amount of output each worker can ...
The Heckscher–Ohlin theorem is one of the four critical theorems of the Heckscher–Ohlin model, developed by Swedish economist Eli Heckscher and Bertil Ohlin (his student). In the two-factor case, it states: "A capital-abundant country will export the capital-intensive good, while the labor-abundant country will export the labor-intensive good."
The simplest model which generates a Balassa–Samuelson effect has two countries, two goods (one tradable, and a country-specific nontradable) and one factor of production, labor. For simplicity assume that productivity, as measured by marginal product (in terms of goods produced) of labor, in the nontradable sector is equal between countries ...
The budget-maximizing model is a stream of public choice theory and rational choice analysis in public administration inaugurated by William Niskanen. Niskanen first presented the idea in 1968, [ 1 ] and later developed it into a book published in 1971. [ 2 ]
The wage increase shown in the previous diagram can be decomposed into two separate effects. The pure income effect is shown as the movement from point A to point C in the next diagram. Consumption increases from Y A to Y C and – since the diagram assumes that leisure is a normal good – leisure time increases from X A to X C. (Employment ...
In the productivity model the input volume is used as a production volume measure giving the growth rate 1.063. In this case productivity is defined as follows: output volume per one unit of input volume. In the growth accounting model the output volume is used as a production volume measure giving the growth rate 1.078.
