The Variations Between Macroeconomics And Microeconomics Economics Essay

Economics is the research that handles the production, syndication, and consumption of goods and services, or the materials welfare of humankind. It is the review of how individuals and societies choose to use the scarce resources that mother nature and previous years have provided. Because of scarcity, choices need to be made on a regular basis by all consumers, organizations and governments. That's, economics is the study of the trade-offs engaged when choosing between alternate pieces of decisions.

Opportunity Cost:

Opportunity cost is the price of forgone benefit i. e. the expense of choosing one alternative/thing over other. Samuelson (1989) points out it as the value of another best use (or opportunity) for an financial good, or the worthiness of the sacrificed option. Thus, say that the inputs used to mine a ton of coal have been used to develop 10 bushels of whole wheat. The chance cost of a ton of coal could have been used to develop 10 bushels of whole wheat. The opportunity cost is thus the 10 bushels of wheat that could have been produced but weren't. Opportunity cost is particularly helpful for valuing non-marketed goods such as environmental health or basic safety. Opportunity cost can't continually be measured in financial or material products, but also in form of anything which posses any value. In economics, there are a famous saying that, "there are NO free lunch for anyone". If one is not asked to cover eating a good or a service, there should be some opportunity cost included, another best alternative that might have been produced using those resources, because of the scarce resources that are used up in the creation of those goods or services. Opportunity cost asses the expense of next best alternative foregone by any financial choice made by the average person or society. There is also the chance cost of deciding not to work that is the lost pay foregone

Difference between Macroeconomics and Microeconomics:

Microeconomics and macroeconomics will be the two major categories of economics:

Microeconomics- examines the behaviour of individual economical entities: companies and consumers regarding the allocation of resources and prices of goods and services. It displays and studies the demand-supply system at individual level, effect of income and saving behaviours, costs of creation, maximizing revenue, and the various market set ups. Microeconomics handles the effect of macroeconomic factors and shifts on individual's life.

Macroeconomics- is the study of the behaviours and activities economy as a whole, not only of specific areas, but complete sectors and economies. It offers the functions and characteristics related to the Government Reserve System, unemployment, money supply, inflation, interest rate, international exchanges rate, gross home product, business cycles etc

It also include the result that unemployment brought to the economy like upsurge in unemployment decrease the gross home product of economy, reduces purchasing electric power parity. Its good impact is the decrease in inflation rate which is because of reduced money source followed by increased interest rate. It involves the study of the most prominent economic issue which is inflation. Central lenders usually increases the interest rate (loaning rate) to reduce the money supply which results in less financing, less money deposition (money supply), less income, less purchasing ability hence less inflation. But as a counter effect it also decreases the speed of employment of an country which results in low over-all GDP of this country.

Fluctuations altogether monetary activity are known as business cycles, and macroeconomists are concerned with understanding why these cycles arise. Most unemployment and inflation are caused by these fluctuations. (enotes, 2. 011)

Demand Curve

Demand curve is a visual or diagrammatic representation of the agenda of demand. It is a graphical representation of the relationship between price and amount. Individual demand curve decides the highest price at which an individual is willing to pay for (different levels of) the commodity. Whereas, every single point on the market demand curve depicts the maximum level of the item which all consumers will collectively be willing to buy, under given demand conditions, at every price level.

Demand curve has a negative slope. It slopes downwards from left to right advocating that the number demanded falls with increase in price and vice versa. The factors leading to a downward sloping demand curve can give as follows:

Income impact- Using the fall in cost of a product, the purchasing vitality of consumer boosts. Thus, he can purchase same quantity of commodity with less money or he can purchase greater levels of same commodity with same money.

Substitution impact- When price of the commodity falls, it becomes relatively cheaper compared to other commodities whose price have never changed. Thus, the consumer tends to consume more of the commodity whose price has dropped.

Law of diminishing marginal electricity- It's the basic cause of regulations of demand. The law of diminishing marginal utility says that as an individual consumes more and more units of your commodity, the power derived from it continues on decreasing. To get maximum satisfaction, an individual purchases in such a manner that the marginal tool of the item is equal to the price of the product.

(Management review guide, 2011)

Firm's End result Decision in Short-Run:

The demand shock's seriousness relies on the state of the market, whereas an overall economy will depend on the Curve of Aggregate Supply. When the market has surplus capacity due to continuous costs of production, it is named short run aggregate resource, shown by the smooth part of the AS curve. Rises in AE also improves Y while the Price remains the same.

When the overall economy is facing cost raises, shown as the middle of this graph where the AS curve is sloped diagonally, it is intermediate short run aggregate supply. As shown in the graph, increase in aggregate costs cause increase in result as well as price. When the overall economy face the trend of quickly increasing costs, it is classical short run supply, shown as the vertical area of the AS curve. As shown in graph, raises in aggregate expenses results in increased cost at constant output. Basically, a lot more a demand impact will influence price, the less it will affect result and ends up with steeper AS.

Firm's Output Decision in Long-Run:

As compare to brief run, where in fact the supply curve is the marginal cost curve lays above average adjustable cost, in the long run, a company need to make normal revenue. When price becomes add up to average total cost, it is recognized as the break-even point. Therefore, over time, it will shut down at any price below this. This leads towards the forming of long run source curve above average total cost of the marginal cost curve.

This is to say that for organizations operating in correctly competitive market segments, the source curve can only just be derived from the marginal cost curve. The idea of a 'supply curve' is pointless in monopoly situations due to the fact a monopoly is a price-maker, not a "passive" price-taker.

The firm's long-run average cost curve will depend on the level of costs variance with regards to the scale of procedures. For some firms increase size or size ends up with reduced costs. For the rest, it could cause inefficiency. If increase in the production size of firm decreases the common costs, it could be concluded that there are increasing profits to level or economies of size. Whereas if increase in a firm's size causes higher average costs, then there are lowering returns to range or diseconomies of scale. And if a big change in level doesn't affect the average costs, we can conclude that we now have constant comes back to scale. Since they are found within the company so they are believed as inside economies (or diseconomies) of scale.

Equilibrium Price and Equilibrium Volume:

The selling price of which the supply of something equals the quantity demanded. Price at which the amount of goods producers wish to supply matches the quantity demanders want to purchase


Whereas equilibrium variety can be explained as amount of goods or services sold at the equilibrium price is the number demanded or offered at the equilibrium price.


QS = QD = QE

Where QE reaches equilibrium position

(JoJmnz144, Wiki-answers)

Equilibrium is a state of equality. Market equilibrium is defined as talk about of balance between market demand and offer. Absence of switch popular and/or source will cause constant selling price. As displayed by diagram, the quantity demanded and provided at price P1 are equal. At any price which is above P1, the resource will go over the demand. While at a price below P1, demand will go over the supply. We are able to also say that the prices are termed things of disequilibrium when demand and offer are out of balance. Conditional changes popular or source will bring about shifting the demand or resource curves. Because of this, change in the equilibrium price and number on the market can be viewed, as shown in the graph (courtesy: tutor2u. net).

Thus the clamouring to get more detailed goods might encourage the access of new suppliers in market. Hence, as discovered above the supply will increase because of the access of new rivals which will drive the marketplace for arrangement of new equilibrium price.

Effects of unnecessary demand on market equilibrium:

Market equilibrium is the result of intersection of the demand and supply curves. Their intersection point is the main point where the quantity demanded is equal to the number demanded. Let us consider the excess demand, where the current price is below the equilibrium, as shown in the physique, which shows that at price 0P, the quantity demanded (0Q) exceeds the quantity supplied (0Q). Market competition among the buyers due to the limited quantity of goods available means that consumers begins bidding up the price. Increase in the purchase price results in an expansion in resource as well as the contraction popular which is often dependant on the movement along the curves into the equilibrium point. This may continue until the existence of surplus demand. Eventually, the intersection point of the resource and demand curves, where at price Pe, the number offered Qe exactly, equals the quantity demanded by consumers.

Effects of excessive source on market equilibrium:

As shown in physique, the quantity offered at price 0P (0Q) exceeds the number demanded, which means we have a situation of excess supply, also known as glut in the market. To eradicate surplus supply, sellers will offer to market their products at lower prices. Decrease in price ends up with increased demand and a contraction in source, which may be noticed by the movements along the curves on the equilibrium point. This can continue till there is excess source, until we reach the main point where resource and demand intersects, where at price 0Pe, the quantity supplied and demanded is equivalent on the market.

Equilibrium price and number will change with the switch in virtually any or both of the resource or demand curve. Changes in conditions behind source and demand, apart from price changes, cause the shifts in the resource and demand curves.

Equilibrium position can be influenced by increase or reduction in supply. An increase in resource shifts the resource curve to the right leading to cutting down the equilibrium price with the raise in equilibrium number. Decrease in source will alter the source curve left but will raise the equilibrium price and lower the equilibrium volume. Market device also means that equilibrium is come to at the intersection of those two curves along with the efficiency in allocation throughout the market. Demand curve advocates the indicator of the value that consumers place on a certain product. As the supply curves supply the sign of the manufacturers' cost of product resource.

Perfect Competition:

It is defined as the marketplace situation, where there are a large number of vendors and buyers. In addition, the products provided by retailers are homogenous (indistinguishable/undifferentiated). This creates the problem, under which, no organization can affect the marketplace price of product, and thus each firm is placed within the properly elastic demand curve. This results on the market condition of price takers, where in fact the companies produce as well as sell their outcome at the costs which are dependant on the marketplace.

Assumptions behind a Wonderfully Competitive Market:

1. Many suppliers each with an insignificant show of the market.

2. The same output made by each firm

3. Consumers have perfect information about the prices all sellers on the market charge

4. All companies (industry participants and new entrants) are assumed to have equal access to resources (technology, other factor inputs) and advancements in creation technologies

5. You can find assumed to be no obstacles to entry & leave of organizations in long run

6. No externalities in development and ingestion so that there surely is no divergence between private and public costs and benefits

Perfect competition Graph:

The perfect competition graph is manufactured by plotting, Level of products on x-axis and the price of product on y-axis. It derives the demand curve of the merchandise, as shown in the graph, the curve is perfectly elastic. The access of new businesses or development of existing businesses (if dividends to range are constant) in to the market impacts the (horizontal) demand curve of each individual firm towards the downward shift, bringing down the average earnings, marginal revenue & most importantly the price curve at the same time. The final results ends in the notion that the company will make only normal income (zero economic profit) in the long run.


An oligopoly can be defined as, the marketplace dominated by way of a few large suppliers. In oligopoly market, the amount of market concentration is very high because the major portion of the marketplace is highly dominated (usually taken up) by the best firms. Organizations which lays with within an oligopoly usually produce top quality products (marketing and advertising can be an important feature of competition within such marketplaces) and there's also barriers to accessibility. Another important characteristic associated with an oligopoly is interdependence between organizations. Which means that each firm must look at the likely reactions of other firms on the market when making rates and investment decisions. This creates uncertainty in such market segments - which economists seek to model through the use of game theory. Game theory may be employed in situations in which decision designers must look at the reasoning of other decision designers. It's been used, for example, to look for the formation of politics coalitions or business conglomerates, the maximum price at which to sell products or services, the best site for a manufacturing plant, and even the behaviour of certain types in the have difficulty for survival (Designed from Brittanica).

Major ideas about oligopoly pricing:

In oligopoly, the dominating organizations collaborate to get monopoly earnings by charging the monopoly price.

Oligopoly firms experience price-induced competition to be able to get the same price and earnings as a competitive industry

Price and income of the oligopoly companies retains between your monopoly and competitive ends of the range

Oligopoly firms exercise indeterminate prices and profits due to the difficulties in modelling interdependent price and result decisions

Oligopoly Graph:

The oligopoly graph is manufactured by plotting Level of products on x-axis and the costs and costs of product on y-axis. When the MC curve fluctuates within the discontinuity Abs (between MC and MC) there is absolutely no motivation for the first ever to change its equilibrium outcome, assuming the organization is a revenue maximising oligopolies.

Keynesian Economics:

It is a macroeconomic theory which is based on the ideas of John Maynard Keynes who was an English economist of 20th century. It argues that:

'Private sector decisions may leads toward an result which is macro-economically inefficient. It advocates effective policy general public sector responses, which include central bank's economic policy activities as well as fiscal insurance policy actions by the federal government to be able to stabilize the business enterprise cycle result'.

Keynesian Economics facilitates a mix overall economy framework that is dominated by private sector but have a considerable role of open public sector and the federal government as well. The government can stimulate new development with a moderate outcome if:

The people who acquire this money then spend most on ingestion goods and save the others.

This extra spending allows businesses to employ more people and pay them, which allows a further increase consumer spending.

This economic approach would require a loose monetary plan to remedy a downturn. They concentrate on keeping low unemployment and are prepared to tolerate any inflation that results from simulative economic policies. They asses that if few microeconomic activities can be taken by a major portion of individuals and companies, collectively, where the economy manages below its potential productivity and expansion rate, they can result in inefficient aggregate macroeconomic outcomes. The centralized bottom line of Keynesian economics can get as no strong automatic mechanism moves job as well as output towards the degrees of full employment, in a few situations. This summarized information of Keynesian economics issues with the strategies of financial that assume an extremely strong general inclination that lead toward equilibrium. The 'neoclassical synthesis' combines the Keynesian macro ideas with a micro foundation. It's the conditions of standard equilibrium which enable the adjustment of price to achieve this goal eventually. In broader conditions, Keynesian takes their theory as an over-all theory that is which utilizes the resources at high or low levels, while the previous economics taken into account the truth of full utilization.

Monetarist Economics:

This theory says that the government has a proper economical role in market. It could control the level of inflation (rate of inflation). This can be done by handling the money in circulation. It's the monetary economic view that change in rate of the amount of money resource has major impacts on national outcome in the brief run as well as on the level of prices over long haul. It shows the aims of monetary coverage which can be best fulfilled by targeting the rate of development of the money supply within an economy. Monetarists are actually critics of expansionary fiscal policy. They argue that expansionary fiscal plan will only result in inflation or crowding away and therefore will not be of any help. This theory presents the key points and newspaper that was mainly produced by Milton Friedman, supporting the traditional liberalism.

The theory of rational expectations suggests that households and business will use historical effects of monetary policy to forecast the impact of a preexisting policy and act accordingly.

Households spend more with a loose financial insurance plan to avoid inflation

Businesses will increase their investment with a loose monetary plan to avoid higher costs

Lab or market individuals will work out higher income with a loose monetary policy

Thus it firmly supports monetarist view that changes in financial policy do not have a sustained impact on the current economic climate. They advocates stable and low expansion in the amount of money supply, allows economic problems to resolve themselves. Monetarists are concerned about retaining low inflation and are willing to tolerate a natural rate of unemployment.
