Answer:
New Keynesian economists critique rational expectations by arguing that short-term wage stickiness is brought about by
b. imperfect information and efficiency wages.
Explanation:
The assumption in macroeconomic theories is that economic agents, households, and companies exercise rational expectations. The New Keynesian economics posits that rational expectations have become distorted as a result of market failure, arising from asymmetric information and imperfect competition, thus questioning the ability of markets to self-regulate and self-correct.
Answer:
If the demand curve for a life-saving medicine is perfectly inelastic, then a reduction in supply will cause the equilibrium price to <u>rise and the equilibrium quantity to stay the same</u>.
Explanation:
Perfectly inelastic demand curve indicates the quantity demanded for the life-saving medicine remains the same or does not change in response to a change in price.
Since a part of the law of supply states that the lower the quantity supplied, the higher the price; a reduction in the supply of the life-saving medicine will increase its price.
The combining effect of the two above will lead to an increase in the equilibrium price while the equilibrium quantity will remain the same as it will not respond to the change in price.
The attached graph explains this more clearly. In the graph, the demand curve DD is used to represent the perfectly inelastic demand curve for the life-saving medicine. Therefore, the quantity remains at q no matter the changes, either increase or decrease, in price. Movement from the supply curve S1 to S2 indicates a reduction in supply of the life-saving medicine which causes an increase in the equilibrium price from Po to P1 while the equilibrium quantity stays at q.
This therefore shows that if the demand curve for a life-saving medicine is perfectly inelastic, then a reduction in supply will cause the equilibrium price to <u>rise and the equilibrium quantity to stay the same</u>.
Answer:
a) ME= 1.93
b) confidence interval= (19.59,23.45)
Explanation:
a) Sample of customers is 64, population standard deviation is 6 and confidence level is 99%
Sample mean= 21.52
Sample size= 64
Confidence level= 99%
Population standard deviation= 6
Standard error of the mean= 0.75
Z-value= -2.5758 (From Z table)
Interval half width= 1.9319
Margin of error at 99% confidence interval is 1.93 from the output.
b) Confidence interval
Interval upper limit= 19.59
Interval lower limit= 23.45
99% confidence interval is (19.59, 23.45) from the output.
ME=
= 1.93
Answer:
complying with legal and social obligations
Explanation:
Every organisation runs its business to achieve the objectives of the business.
Further, the organisation seeks to work in an environment which is legally and socially free from any obligations.
The organisation which assumes too have greater citizenship roles automatically aligns the human resource management with the goal of complying with the legal and social obligations.
As with greater citizenship roles there comes greater diversity which helps to ensure the legal and social obligations.
Answer:
15.68%
Explanation:
Now to get the expected return of the portfolio, we need to find the return of the portfolio in each state of the economy. This portfolio is a special case since all three assets have the same weight. To find the expected return in an equally weighted portfolio, we can sum the returns of each asset and the we divide it by the number of assets, so the expected return of the portfolio in each state of the economy will be :
Boom: RP= (.13 + .21 + .39) / 3 = .2433, or 24.33%
Bust: RP= (.15 + .05 −.06) / 3 = .0467, or 4.67%
Now to get the expected return of the portfolio, we multiply the return in each state of the economy by the probability of that state occurring, and then sum. In so doing, we get
E(RP) = .56(.2433) + .44(.0467)
=.1568, or 15.68%
