Question

Consider labor supply in the presence of fixed time costs of work. That is, it takes someone t hours to walk to and from work each day. From a worker’s perspective, time spent on commuting is costly, because it is not enjoyable like leisure time, and employers do not compensate workers for their commuting time. Assume that workers incur no other expenses in travelling to work (i.e., because individuals walk to work, there are no fixed money costs of work). Also assume that both consumption and leisure are normal goods. a. When fixed time costs of work do not exist (i.e., t = 0), carefully graph budget constraint between consumption and leisure. Label the intercepts and slope of this budget constraint (use T, and general labels do not make up numbers). On the same graph, show how budget constraint changes when there are fixed costs of work (i.e., t > 0) b. How does an increase in fixed time costs of work affect reservation wages and the labor force participation rate? Explain your answer both verbally and graphically. c. Now consider those individuals who continue to work before and after the change in fixed time costs of work. For these workers, how does an increase in the fixed time costs of work affect i. hours of paid work, ii. hours of leisure, and iii. consumption of goods? Explain your answer both verbally and graphically.

Explanation / Answer

Companies will hire more labor when the marginal sales fabricated from labor is better than the wage fee, and stop hiring as quickly as the two values are equal.
The factor at which the MRPL equals the prevailing wage cost is the labor market equilibrium.
The marginal determination rule says that a company will shift spending among explanations of creation so long as the marginal benefit of one of these shift exceeds the marginal price.
If the marginal improvement of further labor, MPL/PL, exceeds the marginal cost, MPK/PK, then the corporation might be at an advantage through spending more on labor and not more on capital.
In line with the marginal choice rule, equilibrium within the labor market need to occur where MPL/PL=MPK/PK.
Key words

marginal product: the extra output that can be produced through using a further unit of the input.
Marginal earnings product: The change in whole sales earned via a organization that results from using a further unit of labor.
Capital: Already-produced long lasting goods to be had to be used as a aspect of production, akin to steam shovels (apparatus) and place of work constructions (structures).
The labor market differs rather from the marketplace for items and offerings on the grounds that labor demand is a derived demand; labor will not be favored for its own sake but as a substitute on account that it aids in producing output. Corporations examine their demand for labor via a lens of profit maximization, ultimately searching for to supply the most reliable degree of output and the lowest possible fee.

Labor Market Equilibrium

so as to find the equilibrium number and rate of labor, economists as a rule make several assumptions:

The marginal fabricated from labor (MPL) is reducing;
businesses are fee-takers in the goods market (are not able to affect the rate of output) as well as in the labor market (can't have an impact on the wage fee);
The supply of labor is elastic and increases with the wage expense (upward sloping give); and
firms are profit-maximizers.
The marginal revenue fabricated from labor (MRPL) is the same as the MPL multiplied by the fee of output. The MRPL represents the additional sales that a organization can assume to gain from using one additional unit of labor â it's the marginal advantage to the firm from labor. Below the above assumptions, the MRPL is decreasing as the range of labor increases, and businesses can expand profit by way of hiring extra labor if the MRPL is larger than the marginal fee of that extra unit of labor the wage fee. For this reason, companies will rent more labor when the MRPL is better than the wage expense, and discontinue hiring as soon as the two values are equal. The factor at which the MRPL equals the present wage expense is the labor market equilibrium.

Ideal Demand for Labor: The surest demand for labor is located where the marginal product equals the real wage cost. The curved line represents the falling marginal made from labor, the y-axis is the marginal product/wage expense, and the x-axis is the range of labor.
Optimizing Capital and Labor

in the long run, corporations maximize profit by using deciding on the top-quality blend of labor and capital to provide a given quantity of output. Its possible that an auto enterprise might manufacture 1,000 cars making use of simplest expensive, technologically developed robots and machinery (capital) that don't require any human participation. Its additionally possible that the manufacturer could produce the identical number of autos making use of handiest employee work (labor), without any the aid of machines or technology. For many industries, nevertheless, relying exclusively on capital or solely on labor is extra costly than using some combo of the two.

Corporations use the marginal choice rule in order to decide what combination of labor, capital, and other causes of production to make use of within the construction of output. The marginal determination rule says that a company will shift spending among factors of construction as long as the marginal advantage of the sort of shift exceeds the marginal fee. Imagine that a corporation must decide whether to spend one more buck on labor. To verify the marginal benefit of that buck, we divide the marginal manufactured from labor (MPL) by way of its price (the wage expense, PL): MPL/PL. If capital and labor are the one causes of creation, then spending another $1 on labor at the same time preserving the whole cost consistent way taking $1 out of capital. The fee of that motion would be the output misplaced from cutting again on capital, which is the ratio of the marginal made of capital (MPK) to the cost of capital (the apartment price, PK). Accordingly, the rate of chopping again on capital is MPK/PK.

If the marginal advantage of additional labor, MPL/PL, exceeds the marginal fee, MPK/PK, then the organization will probably be through spending extra on labor and not more on capital. Then again, if MPK/PK is bigger than MPL/PL, the corporation will be better off spending more on capital and not more on labor. The equilibrium the factor at which the organization is producing the highest amount of output at a given cost happens where MPL/PL=MPK/PK.

When labor is an enter to production, organizations rent employees. Businesses are demand labor and staff furnish it at a fee called the wage price. Colloquially, wages refer to only the greenback amount paid to a worker, however in economics, it refers to total compensation (i.E. It involves benefits).

The marginal improvement of hiring yet another unit of labor is known as the marginal made of labor: it is the further earnings generated from the last unit of labor. In conception, as with other inputs to production, organizations will rent staff until the wage expense (marginal fee) equals the marginal earnings fabricated from labor (marginal advantage).

Alterations in supply and Demand

In competitive markets, the demand curve for labor is the same because the marginal income curve. For that reason, shifts within the demand for labor are a perform of alterations in the marginal product of labor. This may arise for a quantity of causes. To begin with, you can assume that a new product or corporation is created that represents new demand for labor of a distinctive style. There are also three foremost causes that may shift the labor demand curve:

technology which affects the output of a unit of labor.
Alterations in the rate of the output which affect the worth of the unit of labor.
Alterations within the price of labor relative to other motives of construction.
Ultimately, the supply of labor is a perform of the populace. A scale back in the deliver of labor will most commonly motive an broaden within the wage cost. The truth that a discount in provide tends to strengthen wages explains why unions and different legitimate associations have in general sought to restrict the quantity of employees of their designated enterprise. Physicians, for instance, have a fiscal incentive to implement rigorous coaching, licensing, and certification standards with a purpose to restrict the number of practitioners and keep the labor supply low.
