Lecture

Supply Analysis: Elasticity and Wage Adjustments

Description

This lecture focuses on the analysis of supply elasticity in the context of a temporary employment agency providing student labor to agriculture. The instructor presents data on hourly wages and the corresponding hours of labor supplied over a year. The relationship between wage rates and labor supply is examined, emphasizing that the supply of hours is primarily influenced by the wage rate. The instructor explains how to calculate the elasticity of supply using a derived supply function, which is represented graphically. The lecture includes practical exercises, such as determining the necessary wage increase to attract a 5% increase in student hours. The instructor discusses the implications of elasticity values, illustrating how different wage levels affect the required percentage change in wages to achieve desired changes in labor supply. The session concludes with a broader application of elasticity concepts to various economic scenarios, reinforcing the importance of understanding supply dynamics in labor markets.

Supply and demand

In microeconomics, supply and demand is an economic model of price determination in a market. It postulates that, holding all else equal, in a competitive market, the unit price for a particular good, or other traded item such as labor or liquid financial assets, will vary until it settles at a point where the quantity demanded (at the current price) will equal the quantity supplied (at the current price), resulting in an economic equilibrium for price and quantity transacted.

Supply (economics)

In economics, supply is the amount of a resource that firms, producers, labourers, providers of financial assets, or other economic agents are willing and able to provide to the marketplace or to an individual. Supply can be in produced goods, labour time, raw materials, or any other scarce or valuable object. Supply is often plotted graphically as a supply curve, with the price per unit on the vertical axis and quantity supplied as a function of price on the horizontal axis.

A wage is payment made by an employer to an employee for work done in a specific period of time. Some examples of wage payments include compensatory payments such as minimum wage, prevailing wage, and yearly bonuses, and remunerative payments such as prizes and tip payouts. Wages are part of the expenses that are involved in running a business. It is an obligation to the employee regardless of the profitability of the company.

A minimum wage is the lowest remuneration that employers can legally pay their employees—the price floor below which employees may not sell their labor. Most countries had introduced minimum wage legislation by the end of the 20th century. Because minimum wages increase the cost of labor, companies often try to avoid minimum wage laws by using gig workers, by moving labor to locations with lower or nonexistent minimum wages, or by automating job functions.

A living wage is defined as the minimum income necessary for a worker to meet their basic needs. This is not the same as a subsistence wage, which refers to a biological minimum, or a solidarity wage, which refers to a minimum wage tracking labor productivity. Needs are defined to include food, housing, and other essential needs such as clothing. The goal of a living wage is to allow a worker to afford a basic but decent standard of living through employment without government subsidies.
