There is a big macroeconomic effect between a minimum wage and a living wage. A minimum wage does take into account differentials in cost of living in various parts of the country, a living wage takes such variation into account. For example, the cost of living in Lagos is not the same as in Jos. If you pay a minimum, employees in Jos will be better off but this may result in unemployment for the people in Jos. Because a living wage takes into account variations in the cost of living within a country, it has much to commend it in a developing country like with frightening levels of unemployment.
