Expert Solution & Answer

Explanation of Solution

Firms always have to decide between making a component or buying it outside. Their decision is always based on criteria like profit expectation and relevant cost of decision making.

Opportunity cost is the opportunity lost by choosing one alternative over the other. Therefore, such decision is based on total economic cost (opportunity cost + external outlays) between the two alternatives available. The one which is lower would be a choice for them. The relevant cost is different in making and buying as the variable and fixed cost differ. So, if the variable cost in contracting out is low, the firms would like to go for buying from the market. However, reliability on quality, timely delivery, and control over operations is questionable.

C1 The following model can be used to study whether campaign expenditures affect election outcomes: voteA = 0 + B₁ log(expendA) + ẞ₂ log(expendB) + ẞ3 prtystrA + u, where voteA is the percentage of the vote received by Candidate A, expendA and expend are campaign expenditures by Candidates A and B, and prtystrA is a measure of party strength for Candidate A (the percentage of the most recent presidential vote that went to A's party). == (i) (ii) (iii) (iv) What is the interpretation of B₁? In terms of the parameters, state the null hypothesis that a 1% increase in A's expenditures is offset by a 1% increase in B's expenditures. Estimate the given model using the data in VOTE1.DTA and report the results in usual form. Do A's expenditures affect the outcome? What about B's expenditures? Can you use these results to test the hypothesis in part (ii)? Estimate a model that directly gives the t statistic for testing the hypothesis in part (ii). What do you conclude? (Use a two-sided…
