Answer:
change; over-estimates
Explanation:
Substitution bias refers to a tendency in which economic index numbers don't include information about the changes in consumer spending when they switch expensive products for cheaper ones or buy less units as prices change. This changes are not reflected in the market basket from which the CPI is built which can cause inflation rates to be over-estimated.
 
        
             
        
        
        
Answer and Explanation:
The computation of the service level and the corresponding optimal stocking level is shown below:
Given that 
Selling price = SP = $4.50
Cost price = CP  = $3.00
So, 
Salvage value =  V  = $1.50
Average daily demand (d) = 35 quarts
The  standard deviation of daily demand  = 4 quarts
based on the above information 
Overage cost = (Co) is 
= CP - V 
= $3.00 - $1.50 
= $1.50
Now
Underage cost= (Cu) 
= SP - CP 
= $4.50 - $3.00 
= $1.50
So,  
Service level is 
= Cu ÷ (Co + Cu) 
= 1.50 ÷ (1.50 + 1.50) 
= 1.50 ÷ 3.00 
= 0.50 
= 50%
Now 
At 50 % service level, the value of Z is 0 
So, 
Optimal stocking level is 
= d + Z × standard deviation 
= 35 + (0  × 4)
= 35 + 0  
= 35 quarts
 
        
             
        
        
        
Answer:
<h2>In this case,visit to the Butchart Garden is an excludable and non-rivalrous good and is an example of a Club Good.</h2>
Explanation:
First,since the Burchart Gardens charges an admission fee of $30 for each visitor,anyone who has not paid the fee cannot or will not be able to have access inside the garden.Therefore,it is currently not a free service for all the visitors.In this sense,a visit to the Butchart Garden is excludable.It can be assumed that any visitor who wishes to come inside the garden and have a visit will have to mandatorily pay the admission fee.
Secondly,as Butchart Garden is a public area and anyone who pays the admission fee can officially gain access to the garden,enjoyment of the natural and aesthetic beauty of the garden by any one visitor does not reduce the simultaneous enjoyment of any other visitor who has paid the admission fee and hence,gained access to the garden.In economic language,if we consider the garden visit as a particular commodity,then the consumption of the commodity by any one visitor or consumer does not reduce the simultaneous consumption of any other visitor/s or consumer/s,provided that they have all paid the admission fee to gain access to the commodity or garden in this case.Therefore,visits to the Butchart Garden can be considered as non-rivalrous.
Now,since the visit to the Butchart garden is both excludable and non-rivalrous in nature,it can be considered as an example of a Club Good.
 
        
             
        
        
        
Answer: socially wasteful
Explanation:
Product differentiation is when a product is being distinguished from similar products in order to make it more appealing and therefore drive consumers choice. 
It should be noted that critics of market-oriented economies may argue that product differentiation is socially wasteful.
