What are the factors of production? - The factors of production or the inputs include Labor (L) and Capital (K) What is a production function? - The production function tells us how much input (Y) is produced for any given amount of input. The formula is Y = F(K,L), where F is the function that changes K, L to output. What are the components of Cobb - Douglas (CB) production function? - The components of the CB production production function include Capital (K), Labor (L), and A (Total Factor Productivity) What are the three components in CB production function? - The three components of the CB production production function include Capital (K), Labor (L), and A (Total Factor Productivity) What do the exponents in the CB function represent? - The exponents in the CB function represent labor and capital. Capital (K) is raised to the .7 power and Labor (L) is raised to the .3 power because the shares of the labor and capital income remain constant overtime. What is A in the CB function? How do you calculate A? - The A in the CB function can be described as Total Factor Productivity. You can calculate A, by dividing the output (Y) by the (Labor raised to the .3 power x Capital to the .7 power) What is constant returns to scale? - Constant returns to scale is when the total production increases, the value of the good also increases. What is diminishing marginal product? - Diminishing marginal product can be described as when the amount of one factory input increases (Other inputs constant, the marginal product declines. What is MPL and what is MPK? - MPK shows us how much output increases for each unit of capital holding other inputs constant. MPL indicates how much output increases for each unit of labor, holding other inputs constant.
What is a positive supply shock? - A positive supply shock is a positive change in the output an economy can produce from the amount of capital and labor. What is a response function to a negative supply shock in terms of MPK? - The response function to the negative supply shock would be the output at any level of capital would decrease. This would cause the slope of the production function to decrease. What explains the richness and poorness of the country? - By measuring per capita income, we can see the average income of each working citizen. With the per capita income we can also see the productivity efficiency of the economy and the amount of capital per person. How is the richness of a country measured? - Richness of a country is measured by its per capita income. What is perfection competition? - Perfect Competition are firms that take the market prices as given since they do not have the power to change prices. What are economic profits? - Economic profit can be defined as the revenue from selling goods and services minus the cost of the input. What are the key components of economic rents? - The key component of economic rent include the revenue of selling goods and services, the cost of using capital, and the cost of labor. What is the cost of capital and labor called? - The cost of capital is called the rental price of capital, while the cost of labor is called the wage rate or the price of labor. What is the difference between real rental cost and real wage rate? - The real rental cost is the price of capital in terms of good and services, while real wage rate is the wage in terms of good and services. What are the symbols that represent MPL and MPK.
- The symbol that represents MPK is RC (R/P), and MPL is represented by W (W/P). What determines the MPL and MPK? (This will be on your exam and most of you will get it wrong) - MPL determined by change in output that results from adding another unit of labor. MPK is determined by the change of price that is attached to income that could have been lost if capital was rented out elsewhere besides production. What does excess supply affect wage rage? - If there was excess labor, it would cause employers to lower wages since they have enough employees already. What is national income divided into? - National income can be divided into Real Labor Income + Capital Income. Another way could be Y = .7 Y + .3 Y What determines real wages over time? - Real Wages are determined by the marginal force of labor. W = MPL = .7(Y/L)
