Should we stop adding workers when the MP starts to decrease or when it becomes nega1ve? Now, let's change technology: all workers run from bucket to bucket Labor 1 2 3 4 5 6 7 8 9 10 11 Total Product Average Product Marginal Product 3 SR Produc1on Func1on Graph w/ both technologies Discussion Which technology is be_er? What are some other possible technologies? 4 Now, let's switch to the long-run We can choose K and L so let's try a bunch of combina1ons and see which ones give us the same Q LR Produc1on Schedule Capital 3 buckets 3 buckets 3 buckets 3 buckets 3 buckets 4 buckets 4 buckets 4 buckets 4 buckets 4 buckets 4 buckets Labor 2 3 4 5 6 2 3 4 5 6 7 Total Product 5 LR Produc1on Func1on Graph Discussion Why is there diminishing technical rate of subs1tu1on? 6 Let's introduce profit (SR case) Let PQ=$5, PL=$10, PK=$10 (where K=bucket) Labor 1 2 3 4 5 6 7 8 9 10 11 Total Product Total Revenue Total Cost Profit SR Profit Max Graph 7 LR Profit Schedule Let PQ=$5, PL=$10, PK=$10 (where K=bucket) Capital 3 buckets 3 buckets 3 buckets 3 buckets 3 buckets 4 buckets 4 buckets 4 buckets 4 buckets 4 buckets 4 buckets Labor 2 3 4 5 6 2 3 4 5 6 7 Total Product Total Revenue Total Cost Profit LR Profit Max Graph 8 ...
