Introduction to Macroeconomics


1- Introduction to Macroeconomics

The word economy comes from the Greek word 'Okimonos' which implies a dealing with a household. In the beginning,  its origin could appear to be particular, however as a matter of fact, household and economy have a lot more similarities. There is no secret what an economy is. It is only a gathering connecting of individuals or households through the process of economic activities while they are in pace of running their lives. The way of behaving of an economy mirrors the way of behaving of people corresponding to production, distribution, trade and consumption of services and products in a region or a country. Briefly, it is the aggregate of all the required transactions between individuals, organizations and nations.


Study of economics is the investigation of how society deals with its limited resources. In most nations, the resources are dispensed not by an almighty tyrant but rather through the consolidated activities of millions families and firms. Consequently, in economics we concentrate on how individuals decide, the amount they work, the amount they acquire, save, and spend. We likewise concentrate on how individuals interface with each other, for example, how a number of purchasers and dealers of a product or service together determine the price at which it is purchased and sold. Ultimately, we analyze powers and patterns that influence the economy overall including growth in average earnings, the portion of population that stay jobless and the rate at which prices are getting up and so on.


The modern economics has been divided into two major branches as microeconomics and macroeconomics. The prefix 'macro' was first coined and used in the word economics by Norwegian economist Ragnar Frisch in 1933, in his paper 'Proposition Problems and Impulse Problems in Dynamic Economics' published in 'Economic Essay in the Honor of Gustav Cassel' (London 1933). However it was originated with the mercantilists in 16th and 17th centuries as a methodological approach to economic problem. They were concerned with the economic system as a whole. In 18th century, the physiocrats adopted in their 'Table Economique' to show the circulation of wealth among farmers, landlords and unproductive class. Similarly Malthus, Sismondi and Marx dealt with macroeconomic problems in 19th century and Walrus, Wicksell and Fisher had also contributed to the development of macroeconomics. Some other economists like Cassel, Marshall, Pigou, Robertsion, Hayek and Hawtrey developed a theory of money and general prices during the period of First World War. However the subject matter of economic science was still limited to what is called microeconomics until The Great Depression of 1930s.


Macroeconomics appeared as a different part of economic science in 1936 with the publication of a famous British economist John Maynard Keynes' progressive book 'The General Theory of Employment, Interest and Money' briefly known as 'The General Theory.' This book is supposed to be the foundation of macroeconomics as his hypothesis made a solid break from the old style and neo-traditional financial aspects of classical and neoclassical perceptions, and created such a crucial and strong reasoning that his macroeconomic procured the names as 'Keynesian Revolution' and 'New Economics'. Keynes, in his analysis, made a frontal attack on classical perceptions which based on the thought of full employment and involuntary joblessness couldn't prevail in a free market economy. In fact, the classical perception of full employment proved to be ineffective to take care of the monetary issues made by the economic crisis of the early 1930s. However, Keynes through his analysis showed how the equilibrium level of income and employment is determined by the total demand and total supply and further that, due to deficiency of aggregate demand, income level and employment lies below the full employment level in a free market economy. This causes a involuntary joblessness on the one hand and abundance capacity on the other hand. His macroeconomic model uncovers how consumption function, investment function, liquidity preference function imagined in total terms, collaborate to decide the degree of national income and employment.


Since Keynesian progressive economics became posted and got here on effect, it added new thoughts to deal with the financial troubles which were to be constantly debated by the politicians, the press and the public. The query to be debated the various politicians have been, how can the economic system of a state be uplifted rapid presenting the residents hastily improving living standard. Why there are the fluctuations in economies at the same time as other nations' economies are highly stagnant? Why does unemployment on occasion reach very high tiers and every so often, even at some stage in the time of surprisingly prosperity, there's a considerable fraction of the work pressure unemployed? Why do costs of products and offerings rise up and what may be accomplished about it? How to financial links amongst countries, such as international exchange and borrowings, affect the overall performance of an individual economic system and the sector's economies as an entire? And how must monetary policy be conducted in an effort to preserve the economy as rich and stable as feasible? Macroeconomics seeks to provide answers to such questions which can be of super realistic significance.


2- Meaning of Macroeconomics

The phrase 'Macroeconomics' is the blended form of the two words 'macro' and 'economics'. The word 'macro' used as a prefix,  have been derived from Greek word 'makros'. In Greek language, 'makros' means massive. Hence, it implies that macroeconomics is the study of economic system in aggregates, all units of the economy or the economic system as an entire. In other words, it's far the look at of things that decide the extent of aggregate production, employment and prices in an economic system and their rates of change over the years. Thus, macroeconomics offers with such normal monetary issues as unemployment, inflation, recession, despair, growth, instability and stagnation. Its variables are countrywide income, gross national production, countrywide wealth, combination employment and unemployment, the general rate degree and the price of increase of the economy. The which means of macroeconomics may be clean from its definitions and the outline given below.


'Macroeconomics issues the general size of monetary existence. More specially, macroeconomics issues itself with such variables as combination extent of an economy, with the volume to which its resources are hired, with size of countrywide profits, with the overall price level', - Garden Ackely.


'Macroeconomic concept is the theory of income, employment, prices and money', - J. M. Culbortson.


'Macroeconomics is the study of the character, relationships, and conduct of aggregates of financial portions... Macroeconomics deals no longer with character portions as such however with aggregates of these quantities, not with person earning but with the countrywide earnings, no longer with man or woman costs however with the price degree, no longer with person output however with the national output',- K.E. Boulding.


'Macroeconomics is the take a look at of the behavior of the financial system as an entire. It examines the overall stage of a state's output, employment, costs and foreign alternate', - P. A. Samuelson.


The definitions of macroeconomics given above are fairly comprehensive yet they will not screen the exact nature of contemporary macroeconomics nor fully seize its problem count. However, these definitions do give an concept of the critical subject matter of theoretical macroeconomics. The valuable subject that emerges from the above definitions can be said as follows.


Macroeconomics is essentially the take a look at of the conduct and performance of the economic system as an entire. More importantly, it studies the relationship and interplay among the factors and forces that decide the level and growth of national output and employment, preferred rate degree and the stability of price, position of an economy and many others.
