Chapter 9 Lecture 1 ( Shut down problems) Example 1

JJoanna6y ago
Hi John, I hope you're alright. I saw the below question from a fellow student under the above lecture and it perfectly summed up what I wanted to ask so I'm just going to copy and paste it: In part a), it says that Rooks fixed costs are $18,000 but of those, $5,000 are direct fixed costs which could be saved if production ceased. That leaves $10,000 fixed costs that are still being incurred regardless of Rooks not being produced. Thus, in part b), if crowners incur extra direct fixed costs of $6,000, shouldn’t we take into consideration as well those $10,000 fixed costs? How are those $10,000 fixed costs left treated then? Many thanks!

If we stop producing Rooks, then the specific fixed costs of $5,000 will not be incurred but the remaining $13,000 (I don't know where you get $10,000 from) will still be incurred. (So total fixed costs for the business will be $50,000 instead of $55,000) In part (b), yes we do take into account the extra $6,000 fixed costs (and I do so in the lecture!). (And the total fixed costs for the business will be $56,000). The question does not ask what the profit will be, it asks for the decision. You can take either of two approaches: Either work out the total profit in each case - if it increases then good, if it falls then bad. Alternatively, just look at what the change in the profit will be - if there is extra profit then good, if there is less profit then bad. It is the second approach that I take in the lecture (and in the printed answer) because it is faster and much more efficient.
