The number of hours worked per day, H, equals 24 minus the hours of leisure or non-work, N, in a day: Using consumer theory we can determine the demand curve for leisure if we know the price (opportunity cost) of leisure (which is the hourly wage rate). This is the income e↵ect. Thus, with the rise in wage rate, supply of labour has decreased by L0L1. Whereas income effect of the rise in wage rate tends to reduce supply of labour substitution effect tends to increase it. A fourth choice would involve less income and much more leisure at a point like D, with a choice like 50 hours of leisure, 20 hours of work, and $240 in income. Second, X faces a budget constraint. MRS between income and leisure) equals the wage rate (i.e., that is, the market exchange rate between the two. • The framework used to analyse labour supply behaviour is the Neoclassical Model of Labour-Leisure Choice , i.e. Content Guidelines 2. It will be seen from Figure 11.14 that the given income- leisure line MT is tangent to the indifference curve IC2 at point E showing choice of OL1 of leisure and OM1 of income. Thus the larger is the gap between the area between the line OB and the Lorenz curve in the extent of income inequality. Income-consumption curve is a graph of combinations of two goods that maximize a consumer’s satisfaction at different income levels. Income- ... Based on the framework … TL1 is the hours worked at the wage rate w represented by the slope of the income-leisure line MT. In other words, to increase leisure by one hour, an individual has to forego the opportunity of earning income (equal to wage per hour) which he can earn by doing work for an hour. Further, he is better off than before as he is now at higher indifference curve IC2. Our mission is to provide an online platform to help students to discuss anything and everything about Economics. The Gini-coefficient is measured by the ratio of the inequality area to the area of triangle OAB. Again, let’s proceed with a concrete example. Vivian has 70 hours per week that she could devote either to work or to leisure, and her wage is $10/hour. This is a substitution effect of the rise in wage rate which tends to reduce leisure and increase labour supply (i.e. A Lorenz curve is a graphical representation of income inequality or wealth inequality developed by American economist Max Lorenz in 1905. For simplicity we assume that the price of each of these goods he consumes is Re. A fourth choice would involve less income and much more leisure at a point like D, with a choice like 50 hours of leisure, 20 hours of work, and $240 in income. This is illustrated in Fig 11.18 where in panel (a) wage offer curve is shown, and in panel (b) supply curve of is drawn corresponding to leisure-work equilibrium in panel (a). Here is an elaborated discussion on the effect of labour-leisure choice on the supply curve. An increase in non-wage income = - increase in equilibrium income (work same earn more b/c higher wage) - increase in equilibrium leisure (work less earn same - more lesiure) New eqm upward and to the right of initial eqm. The supply curve of labour (or the supply curve of hours worked) is the mirror image of the demand curve for leisure. Thus, the maximum amount of leisure time that an individual can enjoy per day equals 24 hours. The horizontal axis shows both hours of leisure, V (non-work) which are measured from left to right and hours of work, H which are measured from right to left. Choice of other points on income-leisure line MT will show different amounts of leisure, income and work. Now suppose that wage rate rises to w0 with the result that income- leisure constraint line rotates to TM1. TOS4. amount of money to achieve the original 18 utils. Now, with TM1 as new income-leisure constraint line, the individual is in equilibrium at point H at which he supplies TL1 work-hours of labour which are less than TL0. It is plotted by connecting the points at which budget line corresponding to each income level touches the relevant highest indifference curve. A third choice would involve more leisure and the same income at point C (that is, 33-1/3 hours of work multiplied by the new wage of $12 per hour equals $400 of total income). While leisure yields satisfaction to the individual directly, income represents general purchasing power capable of being used to buy goods and services for satisfaction of various wants. •T: Net lump sum taxes, net of transfers curve has a rich history in the literature on increasing female labor force participation. The income effect expresses the impact of higher purchasing power on consumption. D) an upward-sloping labor supply curve. The Lorenz curve would follow the right angled line OAB. How the effect of rise in wage rate is split up into income effect and substitution effect is shown in Fig 11.17. To break up this wage effect on labour supply, we reduce his money income by compensating variation in income. It will be seen from Fig. TM0 as budget constraint) L0 amount of work-hours (labour) are supplied. Indifference curves between income and leisure are therefore also called trade-off curves. will work less hours). In the labor-leisure choice, each indifference curve shows the combinations of leisure and income … Thus, he has sacrificed L1L2 more leisure to do overtime work and earns M1M2 more income than before. Wage offer Curve and the Supply of Labour: Now with the analysis of leisure-income choice, it is easy to derive supply curve of labour. 11.18. The slope of his budget constraint is – w 1 because each extra hour of leisure he enjoys costs him w, goods. With TM1, he reaches his old equilibrium position at point H where he supplies TL1 work- hours. It is important to note that leisure is a normal commodity which means that increase in income leads to the increase in leisure enjoyed (i.e. Mr. A maximises his utility given the two constraints he faces. The economic logic is precisely the same as in the case of a consumption choice budget constraint, but the labels are different on a labor-leisure budget constraint. Interestingly, this is not always the case! The Lorenz curve, introduced more than 100 years ago, remains as one of the main tools for analysis of inequality. Now, we can bring together the indifference map showing ranking of preferences of the individual between income and leisure and the income-leisure line to show the actual choice of leisure and income by the individual in his equilibrium position.
