The Industrial Revolution was a period of transition, and a long one at that. Prior to this time, almost everyone worked from their home, and their pay was subject to the whims of the market. But by 1840, a new kind of economy had emerged. One with large corporations, wage labor, and career paths. This structure was both a source of stability and disruption, and has changed the fabric of economic life.
Why do some jobs pay more than others? Just like the paradox that mostly-useless diamonds are worth more than life-giving water, the answer is supply and demand. Wages are set by the market for labor and the interaction of the supply of labor and the demand for labor. Each of us, for our own reasons, are willing to work a job if the pay is right. And firms are willing to hire us if the work we do increases the bottom line by more than our salary.
The big transition from household-based production to firm-based production meant that ordinary people relied on wage labor for their livelihoods. And since more jobs required specific knowledge and skills, transitions became harder. And so a greater focus was put on the concept of unemployment, or the number of workers currently out of work.
1. The table below shows the number of hours workers are willing to work at each wage, as well as the marginal product of labor.
What will be the wage paid to workers? How many hours of work will be hired?
In the first table, we see how many hours workers will supply at each wage. If the firm only pays $8 an hour, the few workers willing to accept the wage will only work a collective total of 100 hours.
In the second table, we see how much the firm is willing to pay for a certain number of hours of work. If the going wage is $20 an hour, they would be willing to hire up to 100 hours, but not more than that.
So, its obvious that the firm will at least hire 100 hours of work. They can get it for $8/hour, while it benefits their bottom line by $20/hour.
As you work down the chart, you will see that the firm is willing to pay more than what workers are willing to accept. Firms would pay up to $18/hour for 125 hours of work, but they can attract that many workers at only $9/ hour.
If the going wage is $12/hour, then workers will want to supply 200 hours of work to the firm, and the firm will want to hire 200 hours. This match is what sets our equilibrium. It is where supply and demand are crossing (graph it out to see!).
At 225 hours, workers need $13, but the firm will only pay $10, so it won't happen. It just isn't worth it to the workers or to the firm.
So, the wage paid to workers (all of them if the market is sufficiently competitive) is $12 per hour, and 200 hours of work will be hired at that wage.
2. Suppose a country has a civilian noninstitutional population age 16 and over of 35 million people. Of those 35 million people, 7 million do not have a job and are not looking for one, while 26,740,000 are currently employed. What is this country's unemployment rate?
The unemployment rate is calculated as:
(# of Unemployed) / (Labor Force)
The question does not tell us either number, but gives us enough information to figure both of them out. Let's start with the number of unemployed. We know that the 26,740,000 people currently employed are part of the labor force. That leaves 8,260,000 people who are in the eligible population but without a job.
The question tells us that 7 million people don't have a job and are not looking for one. That means these 7 million people are not in the labor force (you must be actively looking for a job or have one to be in the labor force). So, the remaining 1,260,000 people don't have a job and are looking for one. That is our # of Unemployed.
The labor force consists of the employed (26,740,000) and the unemployed (1,260,000). Adding those together gives a labor force of 28,000,000 people.
With those two numbers, we can find the unemployment rate:
1,260,000 / 28,000,000 = 0.045 or 4.5%
Trade Unions were common throughout human history, and largely protected the interests of powerful guilds. But as firms grew larger and larger after the Industrial Revolution, they started to exert a lot of power over the lives of their workers. Abuses of this power led to the formation of labor unions, which pushed back against the bosses and fought for better working conditions and better pay. While union membership has waned in the last half-century, they were an important political force in balancing the power in labor markets.
One cannot stress enough that the real winners of the Industrial Revolution were the poor. Innovation has lifted the wages of typical workers 16-fold (60-fold in the U.S.!). But one also cannot ignore the incredible levels of wealth that have been achieved by a lucky few. Business Tycoons built industrial empires, shutting down their competition, and accumulating an unreasonable amount of influence over the economy. While the superrich are still with us, their ability to build monopolies has thankfully been stifled by regulations which promote competition.
Deeper Thoughts and Extra Practice
I love this video from Veritasium, which explores the history of planned obsolescence and a true conspiracy on the part of light bulb manufacturers. This is a great example of Trusts, anti-competitive agreements, and the now 'visible hand' of corporate management trading economic efficiency for higher profits. You'll also hear stories about how technological anxiety continues to stifle innovation.
Example Question
The marginal product of labor for a firm is given by: MPL = 128 - 2H, where H is the number of hours they hire workers to work. For example, the marginal product of the first hour of labor would be 128 - 2*1, and the marginal product of the second hour of labor would be 128 - 2*2, and so on.
The competitive market wage is $13 per hour, but a labor union has pushed those wages up by $5 per hour. How many fewer hours of labor will the firm hire due to the higher wages?
Round your final answer to two decimal places.
