Etymology[ edit ] Originally, political economy meant the study of the conditions under which production or consumption within limited parameters was organized in nation-states.
Major expenses in building are for land, materials, and labour. In each case they are high when the commodity is scarce and low when it is abundant, and they influence planning more directly when they become restrictive. Definition No one has ever succeeded in neatly defining the scope of economics.
Perhaps the only foolproof definition is that attributed to Canadian-born economist Jacob Viner: Difficult as it may be to define economics, it is not difficult to indicate the sorts of questions that concern economists.
Among other things, they seek to analyze the forces determining prices —not only the prices of goods and services but the prices of the resources used to produce them. This involves the discovery of two key elements: These questions are representative of microeconomicsthe part of economics that deals with the behaviour of individual entities such as consumers, business firms, traders, and farmers.
The other major branch of economics is macroeconomicswhich focuses attention on aggregates such as the level of income in the whole economy, the volume of total employment, the flow of total investmentand so forth. Here economists are concerned with the forces determining the income of a country or the level of total investment, and they seek to learn why full employment is so rarely attained and what public policies might help a country achieve higher employment or greater price stability.
But these examples still do not exhaust the range of problems that economists consider.
There is also the important field of development economicswhich examines the attitudes and institutions supporting the process of economic development in poor countries as well as those capable of self-sustained economic growth for example, development economics was at the heart of the Marshall Plan.
In this field the economist is concerned with the extent to which the factors affecting economic development can be manipulated by public policy. Cutting across these major divisions in economics are the specialized fields of public financemoney and bankinginternational tradelabour economicsagricultural economicsindustrial organization, and others.
Economists are frequently consulted to assess the effects of governmental measures such as taxationminimum-wage laws, rent controls, tariffschanges in interest rates, changes in government budgetsand so on.
Historical development of economics The effective birth of economics as a separate discipline may be traced to the yearwhen the Scottish philosopher Adam Smith published An Inquiry into the Nature and Causes of the Wealth of Nations.
There was, of course, economics before Smith: The unintended effects of markets The Wealth of Nations, as its title suggests, is essentially a book about economic development and the policies that can either promote or hinder it.
In its practical aspects the book is an attack on the protectionist doctrines of the mercantilists and a brief for the merits of free trade. That is, each person takes prices as they come and is free only to vary the quantities bought and sold at the given prices.
But this is true only if the competitive system is embedded in an appropriate legal and institutional framework—an insight that Smith developed at length but that was largely overlooked by later generations. Their imperfections notwithstanding, these theories became the building blocks of classical and modern economics.
This book acted, in one sense, as a critical commentary on the Wealth of Nations. Ricardo invented the concept of the economic model —a tightly knit logical apparatus consisting of a few strategic variables—that was capable of yielding, after some manipulation and the addition of a few empirically observable extras, results of enormous practical import.Fulfillment by Amazon (FBA) is a service we offer sellers that lets them store their products in Amazon's fulfillment centers, and we directly pack, ship, and provide customer service for these products.
