Unemployment (or joblessness) occurs when people are without work and actively seeking work. The unemployment rate is a measure of the prevalence of unemployment and it is calculated as a percentage by dividing the number of unemployed individuals by all individuals currently in the labor force. During periods of recession, an economy usually experiences a relatively high unemployment rate. In a 2011 news story, Business Week reported, "More than 200 million people globally are out of work, a record high, as almost two-thirds of advanced economies and half of developing countries are experiencing a slowdown in employment growth".
There remains considerable theoretical debate regarding the causes, consequences and solutions for unemployment. Classical economics, new classical economics, and the Austrian School of economics argue that market mechanisms are reliable means of resolving unemployment. These theories argue against interventions imposed on the labor market from the outside, such as unionization, minimum wage laws, taxes, and other regulations that they claim discourage the hiring of workers. Keynesian economics emphasizes the cyclical nature of unemployment and recommends interventions it claims will reduce unemployment during recessions. This theory focuses on recurrent shocks that suddenly reduce aggregate demand for goods and services and thus reduce demand for workers. Keynesian models recommend government interventions designed to increase demand for workers; these can include financial stimuli, publicly funded job creation, and expansionist monetary policies.
Types of Unemployment:
Classical or real-wage unemployment occurs when real wages for a job are set above the market-clearing level, causing the number of job-seekers to exceed the number of vacancies.
Many economists have argued that unemployment increases the more the government intervenes into the economy to try to improve the conditions of those without jobs. For example, minimum wage laws raise the cost of laborers with few skills to above the market equilibrium, resulting in people who wish to work at the going rate but cannot as wage enforced is greater than their value as workers becoming unemployed. Laws restricting layoffs made businesses less likely to hire in the first place, as hiring becomes more risky, leaving many young people unemployed and unable to find work.
Cyclical or Keynesian unemployment, also known as deficient-demand unemployment, occurs when there is not enough aggregate demand in the economy to provide jobs for everyone who wants to work. Demand for most goods and services falls, less production is needed and consequently fewer workers are needed, wages are sticky and do not fall to meet the equilibrium level, and mass unemployment results. Its name is derived from the frequent shifts in the business cycle although unemployment can also be persistent as occurred during the Great Depression of the 1930s. With cyclical unemployment, the number of unemployed workers exceeds the number of job vacancies, so that even if full employment was attained and all open jobs were filled, some workers would still remain unemployed. Some associate cyclical unemployment with frictional unemployment because the factors that cause the friction are partially caused by cyclical variables. For example, a surprise decrease in the money supply may shock rational economic factors and suddenly inhibit aggregate demand.
Keynesian economists on the other hand see the lack of demand for jobs as potentially resolvable by government intervention. One suggested interventions involves deficit spending to boost employment and demand. Another intervention involves an expansionary monetary policy that increases the demand of money which should reduce interest rates which should lead to an increase in non-governmental spending.
