Q1: (a) Difference between the Keynesian and monetarist views on how an increase in the money supply causes inflation;

(b) Why is the show of the aggregate supply curve important to the Keynesian monetarist controversy in Macroeconomics Help?

Answer:

Keynesian Model Monetarist  Model
In the Keynesian theory, the economy   is mainly divided into two basic features first one is the “real economy” which evaluates factors of material production  like  labour, and the “monetary economy,” which determines  factors of valuation with price level. Keynesians generally believe that real economy mainly based on issuers like reduced labour demand or fiscal policies of Government (Anderton, 2009). It reflects a greater effect on economic growth of the population, inflation recession.

 

Monetarist theory manly include effects of policies regarding the size and structure of the money supply, questions regarding price levels, the market  value of currency  and exchange rate  and the availability of credit. Apart from that   this theory focuses on the economical events that can make tinkle in the amount of money available for use by the economy (Thurow, 2005).  It has a more substantial impact on short-term productivity than do factors such as employment levels, inflation rate control aggregate demand or government fiscal policy like the Keynesian model.

 

In times of Macroeconomics Help recession, when productivity declines and unemployment levels rise, the economists mainly raise the contrast between Monetarist and Keynesian theories of money. Keynesian economists  mainly engaged themselves in seeking the solution to get rid off from the recession by  addressing  weak economic conditions identifying different  fiscal government stimulus  efforts to increase government expenditure, lowering down the  taxation rate and giving the suggestion to  invest in long-term productive output  in a expectation of  increasing economic demand by these policies. On   the contrary, Monetarists giving more emphasis on increasing the supply of money available to lenders and businesses firms, which will create a easier access to credit and be more effective in generating productive growth of the whole economy as the conclude. Sometimes the money regulatory authority like Governments and central banks deploy different economic policies to control recession’s situation and increase the economy in a effective way.

(b) According to Keynesians, Aggregate Supply curve is more horizontal than vertical in the short run so stabilization policy can impact hugely on output and employment but the controversy begin as  Monetarists believe that the economy is inherently stable, they tend to view the Aggregate Supply curve as more vertical so discretionary stabilization policy is not as important (Gillespie, 2011).

Q 3: Using the aggregate demand-aggregate supply (AS-AD) diagram, show how the four unrelated economic events would affect economic activity and the price level.

 Answer:

(a) A significant destruction in economy’s capital stock because of an earthquake:

Graph 1: aggregate demand-aggregate supply (AS-AD) diagram

(Source :Smith D.2012, page-256)

There should be scarcity of the goods as productivity stops completely due to the significant distraction of the infrastructure of the country. Supply should be less and the demands of the necessary and griffin goods should be higher in the level. The total capital stock of the country will decrease in significant level along with total GDP.

(b)  A increase in personal income Tax:

Incensements in personal income tax will demotivate the buyer to buy in general manner. Everybody will try to restrict his or her expenditure in to a certain limit. In addition, as result of that supply of the goods will be there in the market but the demand for the good will decrease in a significant level (Jenkins,2009).

(C)  An increase in exports:

If a country increase their export service then it is obvious that due to cause export the supply of goods and services will be decrease in national level but as the other condition of the economy will remain unchanged the demand on the other hand will increase gradually. In addition with it certainly the cost of the available product will increase in significant level, because of that inflation can be raised.

(d) An improvement in the marketing and selling of firm managers:

If the marketing and selling skills of firm managers of a country increase then due to cause of effective marketing strategy and proper implementation of the sales force the supply of the products band the goods will increase. On the other hand, promotional strategy of the firms attracts people to purchase more and consume in a larger amount. Therefore, the supply and demand of the goods will increase hand by hand and a point of equilibrium will establish (Lansley, 1994).

Q.6. (a) Describe what mpc with formula;

In economics, marginal propensity to consume (mpc) means that the proportion of total income or of an increase in income that consumers tend to spend on goods and services instead of saving it. It is a component of Keynesian macroeconomic theory and is calculated as the 1 unit change in consumption divided by the 1 unit change in income. MPC can be  depicted by a consumption line- a sloped line created by plotting change in income on the horizontal x axis and change in consumption on the vertical y axis .

 Formula:

(MPC) is equal to ΔC / ΔY, where ΔC is change in consumption, and ΔY is change in income. If consumption increases by 75 units for each additional unit of income, then MPC is equal to 0.75 / 1 = 0.7

(b). Assume that GDP rises from $550bn from $650bn, and that this results in consumption of goods and services rising from $340bn to $400bn. What is mpc?

Salutation:

As per the question, As GDP rises from $550 to $650,

The total amount increased in income is $ (650-550) $= $ 100 (ΔY)

As consumption of goods and services rising from $340 to $400,

The total amount of increasement in consumption is $ (400-340) = $70 (ΔC)

Hence, t

mpc will be (ΔC)/ (ΔY) = 70/100 =0.7

(c)

As mpc, remain fixed as 0.7

So, here the total no of increased income (ΔY) =$(700-550)= 150

The level of consumption will be (ΔC)/150=0.7

There fore ,

(ΔC)= 105 and C will be $(340+105) = $445

(d)  The GDP will increase in this case

As the consumption of goods and services 400$, investment is 120$, government expenditure $150, and exports of goods and services is $140 then the level of total aggregate expenditure (E) will he (400+120+150) = 670$

(e) If expenditure is currently $650 then it will be a increase in GDP because to expend more the people will earn more rote balance their propensity of consumption.

 Q 9. The difference between cost-push and demand- pull inflation with diagram:

 

Cost push Inflation Demand pull Inflation
 

Aggregate supply of an economy consist of the total volume of goods and services produced by an economy at a given price level. Cost-push inflation happens when there is a decrease in the aggregate supply of goods and services resulting from an increase in the cost of production. Cost-push inflation mainly occurred when the prices have been “pushed up” by increases the costing of any of the four factors of production (labour, capital, land or entrepreneurship). It is not possible for the companies to maintain profit margins by producing the same amounts of goods and services when it already running at full production capacity with higher production costs and productivity maximized.  In order to maintain the balance, the increased costs are passed on to consumers, causing a rise up in the general price level (inflation) (Wall , 2003).

Demand-pull inflation occurs when there is an incensement in aggregate demand. The demand can be categorized in to four sections of the macro economy like households, businesses, households, governments and foreign buyers.  Due to the over purchasing capacity of those four factors than the economy can produce they engaged into competition of purchase limited amounts of goods and services. Total demand of the economy surpasses the total supply.  Generally, the purchasers obviously “bid prices up”, again that cause inflation. This excessive demand of the economy can be, described as “too much money is chasing too few goods”, and usually occurs in an expanding economy in developed country.

Demand-Pull Inflation:

 

 

(b) Provide causes of two types of inflation:

 Causes of Demand pull inflation:

The first cause of demand-pull inflation can be growing economy of any country. When habitats of demographic land feel confident that they will get better jobs and earn enough for living in future, that their homes and other monitory investments will increase in value, and governing authority is doing the right thing in guiding the economy by implementing newer and effective economic policies, they will spend more instead of saving. They will also increase their spending in credits by investing more in borrowing auto or home loans, or credit cards. It creates gradual and steady price increases for the economy and leads to inflation(Begg et al.2009),.

Expectation of inflation is a second reason for demand-pull inflation. Federal Reserve Chairman Ben Bernanke pointed this out.  According to him, once people expect inflation in near future then they will buy things in present before prices go up further in the future. This increases demand, which then created demand-pull inflation.

Causes of Cost push Inflation:

Big corporate in long run if they can achieve a monopoly over an industry they can easily tinkle the price of the particular product or services according to their profitability and  can create cost-push inflation. This can also be a cause of reducing in supply, because the company controls the supply of that product or service.

Wage inflation is another cause of cost-push inflation. This is when workers have the power for demanding wage increases and to fulfil that companies then pass through the burden of that overhead cost to consumers by marketing the product or service in higher prices. At the end all, this leads to a cost push Inflation.
