A certain manufacturing company has the following data on quantities shipped and unit costs for each of its four products.
| Products | Base-Period Quantities (Year 1)  | 
Mean Shipping
Cost per Unit ($)  | 
|
|---|---|---|---|
| Year 1 | Year 5 | ||
| A | 2,500 | 10.50 | 15.90 | 
| B | 5,000 | 16.25 | 31.00 | 
| C | 6,500 | 12.20 | 17.40 | 
| D | 2,500 | 20.00 | 35.50 | 
Use the price data to compute a Paasche index for the shipping cost if year 5 quantities are 4,000, 3,000, 7,000, and 3,000 for products A, B, C, and D, respectively. (Round your answer to the nearest integer.)

Answer:
1)
| Product | Quantity | Year 1, (base year) | Year 5, (Obs year) | Quantity*obs cost | Quantity*Base cost | 
| A | 2500 | 10.50 | 15.90 | 2500*15.9 = 39750 | 2500*10.5 = 26250 | 
| B | 5000 | 16.25 | 31.00 | 5000*31 = 155000 | 5000*16.25 = 81250 | 
| C | 6500 | 12.20 | 17.40 | 6500*17.4 = 113100 | 6500*12.2 = 79300 | 
| D | 2500 | 20.00 | 35.50 | 2500*35.5 = 88750 | 2500*20 = 50000 | 
| Total | 393600 | 236800 | 
Price index = 393600/236800 *100 =   166.216 
166

1)
Paasche price index formula = 
In our case we have our observational year as year 5 and base year as year 1.
| Product | Year 5 (Obs qty)  | 
Shipping Cost | obs qty * obs cost  | 
Obs qty * Base cost  | 
|
| Year 1 (base year)  | 
Year 5 (Obs year)  | 
||||
| A | 4000 | 10.5 | 15.9 | 
 4000*15.9 = 63600  | 
 4000*10.5= 42000  | 
| B | 3000 | 16.25 | 31 | 93000 | 48750 | 
| C | 7000 | 12.2 | 17.4 | 121800 | 85400 | 
| D | 3000 | 20 | 35.5 | 106500 | 60000 | 
| Total | 384900 | 236150 | 
Passche index = 384900/236150 = 162.98 
163
Final Answer : Paasche price index = 163
2)
Paasche price index formula =

In our case we have our observational year as year 5 and base year as year 1.
| Product | Year 5 (Obs qty)  | 
Shipping Cost | obs qty * obs cost  | 
Obs qty * Base cost  | 
|
| Year 1 (base year)  | 
Year 5 (Obs year)  | 
||||
| A | 3500 | 10.5 | 15.9 | 
 3500*15.9 = 55650  | 
 3500*10.5= 36750  | 
| B | 3000 | 16.25 | 31 | 93000 | 48750 | 
| C | 7000 | 12.2 | 17.4 | 121800 | 85400 | 
| D | 3000 | 20 | 35.5 | 106500 | 60000 | 
| Total | 376950 | 230900 | 
Passche index =376950/230900  = 163.25 
163
Final Answer : Paasche price index = 163
