A worker can accept a job, for example, illustrated by a worker's screen and a firm's screen.
Suppose the worker is paid $8 for a job that resulted in an increase of $13 in revenue.
Worker payoff: $13 (revenue) - $8 (wage) = $5.
The worker's payout for doing the job will be $8.
Reservation Wage
Workers have important information on their potential earnings if they do nothing (e.g., staying at home).
If a rational worker assesses their wage potential, they determine their reservation wage:
Reservation Wage: The minimum wage required for a worker to feel incentivized to make themselves available in the job market.
Perspective: If the offered wage is less than this amount, the worker is better off staying at home.
Firm Perspective
A firm needs to evaluate potential hiring:
When considering hiring a worker, the firm looks at the additional revenue generated by the worker known as the marginal revenue product (MRP).
The typical surplus in a market example might average $53.97, with $69 allocated to a specific firm or individual, reflecting the MRP per hire.
The firm's objective is to hire until:
Wage willing to pay = Marginal Revenue Product.
Equilibrium is reached where the marginal revenue product equals the marginal resource cost.
Productivity and Resource Allocation
Firms need to evaluate how much of each resource (labor, capital, land, entrepreneurship) to employ based on marginal cost and marginal revenue product:
The principle of maximizing profit indicates that firms should hire workers until the marginal cost of hiring equals the marginal benefit (MRP).
Derived Demand: Demand for labor is derived from consumer demand for the goods and services produced by that labor.
Marginal Benefit and Cost
Questions to ask for a firm regarding workers:
If one new trader is estimated to add 5 memberships priced at $100 each:
Marginal benefit = 5 memberships * $100 = $500.
Maximum wage willing to pay a worker for that added value is $500.
Wage determination is reliant on two conditions:
Productivity of the worker
Price of the product produced
If either the product price or worker productivity increases, there’s an increase in the marginal benefit, encouraging hiring at higher wage rates.
Upward sloping supply curve in the overall labor market, even if individual supply curves are backward-bending.
Backward Bending Supply Curve
Concept explained through hypothetical wage increase scenarios:
As wages increase to a certain point, work supplied may increase, but may eventually decrease:
If wages rise from W1 to W2, willingness to work increases.
If wages rise beyond a certain point (W3 to W4), workers may choose to supply less labor, indicating a backward-bending supply curve.
Different workers have different thresholds, leading to varied individual backward-bending curves, affecting overall market supply.
Equilibrium and Shifts in Demand
Equilibrium seen when the labor demand intersects with the labor supply, determining employment levels:
Example: Employment might be 3,000 workers at a wage of $1.
Analysis of external factors:
If the price of products produced declines, demand for labor will shift leftward, leading to:
Decreased employment (e.g., from 3,000 to 2,000 workers).
Lower wage rates in the market.
Relevant scenario examples in the real world:
Companies may shut down if marginal costs exceed their marginal revenues, leading to a decrease in labor demand and subsequent wages.
Effects of Population Changes on Labor Supply
Increase in the working-age population will shift labor supply rightward, indicating an increased labor supply.
Changes in demand can affect the overall labor market:
Decreased number of firms hiring workers leads to a decrease in demand for labor, impacting wage rates accordingly.
A firm's hiring decisions are partially based on wages offered in response to the supply changes.
Conclusion
Understanding wage dynamics, productivity, and market mechanics are essential in evaluating labor market conditions and firm hiring behavior. The interplay of demand and supply forces shapes the employment landscape, influencing the decisions made by workers and firms alike.
