    ? given a wage rate W1 the firm maximizes profits at point B
    o in the upper diagram, the GH isocost line (with slope W1/r) is tangent to the Qb isoquant at point B
     the firm uses Lb units of labor and Kb units of capital to produce Qb units of output
    o in the lower diagram, in the long run the firm hires LB unit of labor when the wage rate is W1; point B is one point on the demand for labor
    ? now suppose that the wage rate decreases to W0
    o the GH isocost line will rotate outwards to the line GF (the horizontal intercept COST/W0 is now located farther from the origin) and the new set of isocost lines will be with slope W0/r.
    o a decrease in the wage rate also shifts firms' ...
