Suppose that, through collective bargaining, a labor union successfully negotiates an industry-wide wage for various kinds of labor (electricians, plumbers, and so on). In particular, it succeeds in negotiating a wage increase for carpenters from $9 to $12 per hour. The following graph shows the demand for labor and the supply of labor for the entire industry. On the following graph, use the purple points (diamond symbol) to plot the new industry supply curve. Then use the black point (plus symbol) to show the effect of the union negotiations on the quantity of labor demanded in the industry.

Further, utilise this function to estimate demand for the following month, on the assumption that: (a) price remains unchanged, (b) price increases to ZMW9/ton. Hence estimate the price elasticity of demand between these prices and find the price which would maximise sales revenue. Given the nature of the observations, comment on any difficulties in interpreting your results for decision-making purposes.arrow_forward
