Market Efficiency The concept of market efficiency was first developed in the finance literature and its full form was first explained by Engene Fama. But now-a-days this concept is being used in other areas also. Market efficiency implies that prices reflect all available information, but it does not imply certain knowledge. Many pieces of information that are available and reflected in prices are fairly uncertain. Efficiency of markets does not eliminate that uncertainty and therefore does not imply perfect forecasting ability. By definition then there should not exist any unexplained opportunities for profit. “An ‘efficient’ market is defined as a market where there are large numbers of rational, profit-maximizers actively competing, with each trying to predict future market values of individual securities, and where important current information is almost freely available to all participants. In an efficient market, competition among the many intelligent participants leads to a situation Continue reading

The Great Depression – Facts, Causes, and Effects
The Great Depression is a term denoting the economic crisis that emerged in the United States and some European countries. The crisis began in 1929 and continued until the end of the 1930s. The term “depression” is mostly used to refer to events solely in the U.S., where virtually entire American nation was particularly strongly affected by a depressive state in addition to the economic decline. The term “global economic crisis” is commonly used for other countries that have experienced the same events (UK, Germany, France, and other European countries to a lesser extent). Large industrial cities had suffered the most from the crisis, but rural areas were also affected. Crises in world history occur from time to time. However, according to the researchers, the Great Depression is one of the most prolonged crises in the history of the industrialized countries. It is considered that it started with the collapse Continue reading
Hawtreys Monetary Theory of Trade Cycles
The British economist Ralph G. Hawtrey regards trade cycle as a purely monetary phenomenon. According to him, non-monetary factors like wars, earthquakes, strikes and crop failures may cause partial and temporary depression in particular sectors of an economy. However, these non-monetary factors cannot cause full and permanent depression involving general unemployment of the factors of production in a trade cycle. On the other hand, changes in the flow of money are the exclusive and sufficient cause of changes in trade cycle. In Hawtrey’s opinion, the basic cause of trade cycle is the expansion and contraction of money in a country. According to Hawtrey, changes in the volume of money are brought about by changes in the rate of interest. For instance, if banks reduce their rate of interest, producers and traders will be induced to borrow more from banks so as to expand their business. Borrowing from banks will lead Continue reading
Balance of Payments (BoP) Accounting
Balance of payments (BoPs) is systematic statement that systematically summarizes, for a specified period of time, the monetary transactions of an economy with the rest of the world. Put in simple words, the balance of payments of a country is a systematic record of all transactions between the ‘residents’ of a country and the rest of the world. Three main elements of actual process of measuring international economic activity are: Identifying what is/is not an international economic transaction, Understanding how the flow of goods, services, assets, money create debits and credits, and Understanding the bookkeeping procedures for BoP accounting. Each transaction is recorded in accordance with the principles of double-entry book keeping. That is every transaction is recorded based on accounting principle. One of these entries is a credit and the other entry is debit. In principle, the sum of all credit entries is identical to the sum of all Continue reading
What is a Circular Economy?
The term circular economy (CE) has both a linguistic and descriptive meaning. Linguistically it is an antonym of a linear economy. A linear economy is one defined as converting natural resources into waste, via production. Such production of waste leads to the deterioration of the environment in two ways: by the removal of natural capital from the environment (through mining/unsustainable harvesting) and by the reduction of the value of natural capital caused by pollution from waste. And the word circular has a second, inferred, descriptive meaning, which relates to the concept of the cycle. There are two cycles of particular importance here: the biogeochemical cycles and the idea of recycling of products. By circular, an economy is envisaged as having no net effect on the environment; rather it restores any damage done in resource acquisition while ensuring little waste is generated throughout the production process and in the life history Continue reading
Economic Systems – Planned Economy, Free Market Economy and Mixed Economy
System of Planned Economy Under the conditions of the planned economy, all decisions concerning what to manufacture, how to manufacture and to whom to manufacture are approved by the sole center or group. This economy is based on collective ownership. Fixed production assets are owned by the government, and resources, production and the quantities of future products are distributed according to a plan. The type of the system of the command economy was prevailing in the USSR, Cuba, and North Korea. The plans of the system of the centralized economy are drawn up and implemented by the authorities and governmental political leaders after consulting with highly ranked professionals: engineers, economists, industrialists, and other experts. These planners decide which products to manufacture and which services to render. Their vote is decisive in approving decisions whether new undertakings are to be constructed, how many employees are to be employed at undertakings, whether Continue reading
