    Revenue

    economics revenue
  • What are the components of costs in the profit formula?

    • Labor costs: WL
    • Capital costs: RK
    economics costs
  • What does 'WL' stand for in the profit equation?

    Labor costs

    economics labor
  • What does 'RK' represent in the profit formula?

    Capital costs

    economics capital
  • When will a firm hire an extra unit of labor?

    A firm will hire an extra unit of labor if its benefit exceeds its cost.

    economics labor
  • What is the cost of hiring labor represented by?

    The cost is represented by the wage, W.

    economics labor
  • What does MPL stand for?

    MPL stands for marginal product of labor.

    economics labor
  • What is the demand for labor equation?

    The demand for labor equation is \(W/P = MPL\).

    economics labor
  • How can the labor demand equation be derived?

    It can be derived by maximizing profits.

    economics labor
  • In a Cobb-Douglas production function, \(Y = K^{\alpha}L^{1-\alpha}\), the demand for labor is given by \(\frac{W}{P} = (1-\alpha) K^{\alpha}L^{-\alpha}\).

  • When will a firm hire an extra unit of capital?

    If its benefit exceeds its cost.

    economics capital
  • What is the cost of capital represented by?

    The interest rate, denoted as R.

    economics capital
  • What represents the benefit of an extra unit of capital?

    The extra revenue due to the extra unit of capital, calculated as P * MPK.

    economics capital
  • What does MPK stand for?

    Marginal Product of Capital.

    economics capital
  • What is the demand for capital equation?

    R/P = MPK.

    economics capital
  • How can we derive the demand for capital equation?

    By maximizing profits.

    economics capital
  • What is the Cobb-Douglas production function?

    Y = K^α * L^(1-α).

    economics production
  • What is the demand for capital under Cobb-Douglas?

    R/P = α * K^(α-1) * L^(1-α).

    economics capital
  • Total labor income is represented as W and is calculated by the formula L/P = MPL.

    economics income labor
  • Total capital income is represented as RK/P and is calculated by MPK.

    economics income capital
  • Under Cobb-Douglas, the total output is given by the formula Y = K^ ext{α} L^{1- ext{α}}.

    economics cobb-douglas production
  • Labor income is calculated as W·L/P and equals (1-α) Υ.

    economics income labor
  • Capital income is calculated as R·K /P and equals α Υ.

  • What do interest rates measure in investment expenditure?

    The cost of funds used to finance investment.

    economics interest_rates
  • What does the real interest rate (r) measure?

    The true cost of borrowing.

    economics interest_rates
  • What is the Fisher equation?

    \(r = i - u\) (nominal interest rate – inflation).

    economics formulas
