Labor economics

Labor economics seeks to understand the functioning and dynamics of the market for labor. Labor markets function through the interaction of workers and employers. Labor economics looks at the suppliers of labor services (workers), the demanders of labor services (employers), and attempts to understand the resulting pattern of wages, employment, and income.

In economics, labor is a measure of the work done by human beings. It is conventionally contrasted with such other factors of production as land and capital(Richard, 2008). There are theories which have developed a concept called human capital (referring to the skills that workers possess, not necessarily their actual work), although there are also counter posing macro-economic system theories that think human capital is a contradiction in terms.

Demand for labor and wage determination

Labor demand is a derived demand, in other words the employer's cost of production is the wage, in which the business or firm benefits from an increased output or revenue (John, 2005). The determinants of employing the addition to labor depend on the Marginal Revenue Product (MRP) of the worker. The MRP is calculated by multiplying the price of the end product or service by the Marginal Physical Product of the worker. If the MRP is greater than a firm's Marginal Cost, then the firm will employ the worker. The firm only employs however up to the point where MRP=MC, not lower, in economic theory.

Wage differences exist, particularly in mixed and fully/partly flexible labor markets(Richard, 2008). For example, the wages of a doctor and a port cleaner, both employed by the NHS, differ greatly. There are many factors concerning this issue. This includes the MRP (see above) of the worker. A doctor's MRP is far greater than that of the port cleaner. In addition, the barriers to becoming a doctor are far greater than that of becoming a port cleaner.

For example to become a doctor takes a lot of education and training which is costly, and only those who are socially and intellectually advantaged can succeed in such a demanding profession(Simon, 2005). The port cleaner however requires minimal training. The supply of doctors therefore would be much more inelastic than the supply of port cleaners. The demand would also be inelastic as there is a high demand for doctors, so the NHS will pay higher wage rates to attract the profession.

The MRP of the worker is affected by other inputs to production with which the worker can work (e.g. machinery), often aggregated under the term "capital". It is typical in economic models for greater availability of capital for a firm to increase the MRP of the worker, all else equal. The education and training noted in the last paragraph are counted as "human capital"(Freeman, 2007).

Since the amount of physical capital affects MRP, and since financial capital flows can affect the amount of physical capital available, MRP and thus wages can be affected by financial capital flows within and between countries, and the degree of capital mobility within and between countries
