==Labor Economics==

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



==Real Wage==
The real wage describes the quantity of goods that the worker gets for a number of hours of labor. the real wage is the nominal wage adjusted to the level of inflation. It determines how much labor workers will want to supply in the economy.

==Factors that Influence Real Wage==

*wealth
*expected future real wage
*population size
*technology
*any change in the price level

==Income Effect==
When wages increase, the income effect states that a worker feels wealthier and that he needs to work less to have the same income. The effect will result in the laborer placing a greater demand on goods, services, and non-market activities so that he/she will cut down on supply of labor.

==Substitution Effect==
The substitution effect is simply  when the laborer feels that  because the wage has increased the worker realizes that by involving himself in non-market activities he is missing the opportunity to increase savings. Therefore, the result will be an increase in the supply of labor. For temporary wage increases the substitution effect dominates.

==Gender Differences==
Men and women are observed to react in a different way to changes in wages. For men, substitution and income effects offset each other, while for women, substitution effect outweighs the income effect. In general though, we assume that substitution effect dominates the economic behavior of people. In this project, we are going to analyze the causes, effects and consequences of this generalization.

==Sex based Wage Inequality==
We consider wage inequality as one of the biggest problems in labor economics. This is why we decided to focus our attention on the wage differential, i.e. why women receive less money for the same quantity and quality of labor. The gap between men and women's payment tends to decrease worldwide, especially in the US, but we fell that this trend deserves serious consideration and analysis. 
For our analysis of the issue, we are using the work of Francine Blau, **** -the book about feminist economics, and the research of Mark Rosenzweig.

==Opportunity Cost of Leisure Time==
One of the main factors that plays a role when anylizing the income and substitution effects is the opportunity cost of leisure time. The importance that a laborer places on leisure time when compared with the want to increase one's income will play the role in determining, which effect will dominate. If there is greater importance on leisure time, than increased income, the income effect will dominate. If their is greater importance on income than leisure time, substitution effect will dominate.
