Keynesian and Classical Economists Views about Disequilibrium

Economists usually define general disequilibrium as the state in which contrasting market forces of supply and demand fail to reach a balance and there exist an intrinsic inclination for change. The main indicator of market disequilibrium is the continuation of shortages either in the demand or supply side of the economy. There are two main models that hold divergent views concerning disequilibrium namely the Keynesian and Classical Economists models. Generally, the major causes for disequilibrium in the markets if the deficiencies created either in the aggregate demand or aggregate supply side of the economy. This means that in such circumstances the market does not clear. Main causes of disequilibrium are understood in the light of the economic model s followed by scholars. For instance, the Keynesian theory’s causes differ from that of classical economists. For instance, following Keynesian’s view, disequilibrium arises when there are disparities between leakages and injections where Continue reading

Theory of Absolute Advantage and Comparative Advantage

Theory of Absolute Advantage   If one region can produce a commodity with less expense than another, and they exchange, then both should benefit. In a nutshell, this is the law of comparative advantage. It is used as the justification for WTO trade regulations. Some land grows corn better than other land. This economical insight into farming in early 18th Century was the cornerstone of the law of absolute advantage. Some farmland will yield more corn per acre than another, therefore the good land confers an absolute advantage over other regions. The conclusion drawn from this argument is that the farmer of the poor land should change products that it can produce to its absolute advantage, such as grazing sheep. The law of absolute advantage is based on the assumption that competition is the best paradigm within which to build an economy, it assumes that competition will improve production. The Continue reading

Price Elasticity Of Demand – Concept and Types

The price elasticity of demand measures the degree of responsiveness of quantity demanded for a certain commodity to the change in its price. In other words, the price elasticity of demand is defined as the ‘ratio of percentage change in the quantity demanded to the percentage change in price. It can be expressed as follows: Price elasticity of demand (ep) = Percentage change in quantity of demand / Percentage change in price Where, ep = Coefficient of price elasticity of demand. The price elasticity of demand is always negative due to the inverse relationship between the price and quantity demanded. But for the sake of simplicity in understanding the magnitude of response of quantity demanded to the change in the price we ignore the negative sign and take into account only the numerical value of the price elasticity of demand. Types of Price Elasticity of Demand There are five types of Continue reading
