The difference between the short-run Philips curve and long-run Philips curve is shown in the diagram below:
On the left, the Aggregate Demand (AD) increases from AD1 to AD2, as the result of an increase in government spending. This increases aggregate income (Y) in the short run and the price level (P) rises. However, in the long run, Aggregate Supply (AS) decreases from AS1 to AS2 because of higher input costs due to inflation and the price level rises again.As a result, Long Run Aggregate Supply (LRAS) is fixed.
On the right, the increases in the price level translate to higher inflation. This leads to lower rates of unemployment (U) in the short run. Starting at a point a, the curve moves to point b. However, as Aggregate Supply decreases, the Short-Run Philips curve shifts up. Moving from point b to point c, the inflation stays high and the unemployment increases. In the long run, the unemployment is fixed with respect to the inflation rate.
Economics Concept Introduction
Philips Curve:
Phillips curve is a graphical representation of the relationship between inflation rate and unemployment. This curve states that there is an inverse relationship between inflation and unemployment.
Aggregate demand:
Aggregate demand is the total demand for final goods and services at a given time.
Aggregate supply:
Aggregate supply is the total supply of goods and services available in a market place.

It is possible to use transformational leadership strategies to reach unethical objectives.
Traditional leadership theories and morals standards are not adequate to help employees solve complex organizational issues.
For the statement above, argue in position for both in favor or opposed to the statements.
Discuss the preferred deterrent method employed by the Zambian government to combat tax evasion, monetary fines. As noted in the reading the potential penalty for corporate tax evasion is a fine of 52.5% of the amount evaded plus interest assessed at 5% annually along with a possibility of jail time. In general, monetary fines as a deterrent are preferred to blacklisting of company directors, revoking business operation licenses, or calling for prison sentences. Do you agree with this preference? Should companies that are guilty of tax evasion face something more severe than a monetary fine? Something less severe? Should the fine and interest amount be set at a different rate? If so at why? Provide support and rationale for your responses.

- "Whether the regulator sells or gives away tradeable emission permits free of charge, the quantities of emissions produced by firms are the same." Assume that there are n identical profit-maximising firms where profit for each firm is given by π(e) with л'(e) > 0; π"(e) < 0 and e denotes emissions. Individual emissions summed over all firms gives E which generates environmental damages D(E). Show that the regulator achieves the optimal level of total pollution through a tradeable emission permit scheme, where the permits are distributed according to the following cases: Case (i) the firm purchases all permits; Case (ii) the firm receives all permits free; and Page 3 of 5 ES30031 Case (iii) the firm purchases a portion of its permits and receives the remainder free of charge.arrow_forwardcompare and/or contrast the two plays we've been reading, Antigone and A Doll's House.arrow_forwardPlease answer step by steparrow_forward
- Suppose there are two firms 1 and 2, whose abatement costs are given by c₁ (e₁) and C2 (е2), where e denotes emissions and subscripts denote the firm. We assume that c{(e) 0 for i = 1,2 and for any level of emission e we have c₁'(e) # c₂' (e). Furthermore, assume the two firms make different contributions towards pollution concentration in a nearby river captured by the transfer coefficients ε₁ and 2 such that for any level of emission e we have C₂'(e) # The regulator does not know the resulting C₁'(e) Τι environmental damages. Using an analytical approach explain carefully how the regulator may limit the concentration of pollution using (i) a Pigouvian tax scheme and (ii) uniform emissions standards. Discuss the cost-effectiveness of both approaches to control pollution.arrow_forwardBill’s father read that each year a car’s value declines by 10%. He also read that a new car’s value declines by 12% as it is driven off the dealer’s lot. Maintenance costs and the costs of “car problems” are only $200 per year during the 2-year warranty period. Then they jump to $750 per year, with an annual increase of $500 per year.Bill’s dad wants to keep his annual cost of car ownership low. The car he prefers cost $30,000 new, and he uses an interest rate of 8%. For this car, the new vehicle warranty is transferrable.(a) If he buys the car new, what is the minimum cost life? What is the minimum EUAC?(b) If he buys the car after it is 2 years old, what is the minimum cost life? What is the minimum EUAC?(c) If he buys the car after it is 4 years old, what is the minimum cost life?
