A local specialty wine store normally sells an average of 129 imported wines from France - per month - over 6 months at an average of $15.86 each. The price elasticity of Demand for these wines is estimated to be -1.64. Recent government regulations, Canadian Dollar value changes and transportation costs have increased costs considerably resulting in higher breakeven prices for all items. In order to capture economic profits the store manager decides to take some action and re-prices the inventory in the store. If the manager increases the price of French Wines by 10% how many bottles of French Wine will they sell? ** HINT - use the basic formula: Elasticity = (Unknown Q / Change in Price) x (Average Price / Average Quantity sold) ** enter your answer for HOW many bottles of French Wine will be sold FOLLOWED by whether the elasticity value is inelastic or elas

1) Production function for agricultural sector of a country is specified as the following, log Y=B1 + B2 log K+ ß3 log L+u. where Y represents wheat output, K capital stock and L employment (labor). The model is estimated using annual data over 1980-2020 (n=41) periods. The results are reported below. p-values are given in squared parentheses. loĝ Y = 4.17 +0.67 log K+ 0.35 log L p-value [0.015] [0.18] R² = 0.81 1.a) Test if each slope coefficient is significant individually (one by one) using the p-values in parentheses and interpret the results.

Use the above to calculate the arc price elasticity of demand between Pr = $20000 decreasing to PT = $10000. AQ P₁ + P₂ The arc elasticity formula is:Ep ΔΡ Q₁ +2₂ (b). Judging from the computation in (1a), do you expect the revenue resulting from the price decrease to $10000 to increase, remain the same, or decrease relative to the revenue at the price of $20000? (Hint: see the table on page 65 of Truett). Explain your choice. 2.(a) Calculate the point price elasticity of demand for Toyotas at PT= $20000 (which should make Q₁ = 270).
