The Labor Market: Workers, Wages, and Unemployment Study Guide

Five Major Trends in the Industrialized Labor Market

• Trend 1: Sustained Real Wage Growth     * Industrialized nations have experienced significant growth in real wages throughout the $20^{\text{th}}$ century.     * By $2018$, real earnings in the United States were approximately twice the level of real earnings in $1960$.     * By $2018$, U.S. real earnings were more than five times the level recorded in $1929$.

• Trend 2: Stagnation in Real Wage Growth and Employment Changes     * The rate of real wage growth has seen a period of stagnation since $1973$.     * Real wage growth was at its fastest during the $1960\text{s}$ and the early $1970\text{s}$.     * Data on annual real wage growth rates:         * $1960 - 1973$: $2.5\%$ per year.         * $1973 - 1995$: $0.9\%$ per year.         * $1996 - 2007$: $1.8\%$ per year.         * $2007 - 2016$: $0.7\%$ per year.         * $1970 - 2012$: $1.1\%$ per year.     * Despite stagnated wages, the total number of people with jobs and the percentage of the population employed has increased substantially.

• Trend 3: Increased Wage Inequality in the United States     * Wage inequality increased markedly between the $1970\text{s}$ and $2018$.     * Workers at the low end of the income distribution saw their average real weekly earnings decrease.     * In contrast, the real wages for the best-educated and highest-skilled workers increased.     * The income for a worker with an advanced college degree is currently:         * Twice the income of a high school graduate.         * Three times the income of a worker who did not graduate from high school.

• Trend 4: Job Growth and Participation Rates     * The number of individuals with jobs has grown substantially over the last $50$ years, although the rate of growth has slowed recently.     * In $1970$, approximately $57\%$ of the population over the age of $16$ was employed.     * By $2000$, this figure rose to $64\%$, and then settled at $61\%$ in $2019$.     * Between $1980$ and $2000$, the number of jobs grew by $38\%$, while the population grew by only $27\%$.

• Trend 5: Higher Unemployment in Western Europe vs. the United States     * Western European nations have suffered from higher unemployment rates compared to the U.S.     * Average unemployment rates from $1990 - 2018$:         * France: $9.9\%$         * Italy: $9.6\%$         * Spain: $16.6\%$         * United States: $5.9\%$     * Similar unemployment challenges are present across many other Western European countries.

The Labor Market: Demand, Supply, and Wage Determination

• Conceptual Overview     * Supply and demand analysis is utilized to determine the price of labor (real wages) and the quantity of labor (employment).     * The analysis focuses on the number of workers employed rather than total work-hours per year.     * The labor market is classified as an input market where firms purchase labor to produce goods and services.     * Macroeconomics analyzes aggregate levels of employment and wages, whereas microeconomics examines wage determination for specific categories of workers.

• The Demand for Labor     * Demand is dependent upon:         1. The productivity of workers: Increased productivity leads to higher employment levels.         2. The price of the worker’s output: A higher real price for the product increases the demand for labor.     * Diminishing Returns to Labor: This principle assumes non-labor inputs are held constant. Adding an additional worker increases total output, but the increment of output added by each subsequent worker is less than the previous one.     * Value of Marginal Product (VMP): This is the extra revenue generated by adding one more worker.     * Case Study: Banana Computer Company (BCC)         * BCC sells computers for $\$3,000$ each.         * Workers (n) and corresponding Marginal Product (MP):             * $n=1$: $25$ computers/year (MP: $25$)             * $n=2$: $48$ computers/year (MP: $23$)             * $n=3$: $69$ computers/year (MP: $21$)             * $n=4$: $88$ computers/year (MP: $19$)             * $n=5$: $105$ computers/year (MP: $17$)             * $n=6$: $120$ computers/year (MP: $15$)             * $n=7$: $133$ computers/year (MP: $13$)             * $n=8$: $144$ computers/year (MP: $11$)     * Hiring Rule: A firm hires an additional worker if and only if the $VMP$ exceeds the wage paid.         * Example: If the wage is $\$60,000$, BCC hires $3$ workers because the $3^{\text{rd}}$ worker's $VMP = 21 \times \$3,000 = \$63,000$ (which is > \$60,000), but the $4^{\text{th}}$ worker's $VMP = 19 \times \$3,000 = \$57,000$ (which is < \$60,000).         * Example: If the wage is $\$50,000$, BCC hires $5$ workers.     * Labor Demand Curve: The curve is downward-sloping; the lower the wage, the more workers a firm will employ.

• Shifting the Demand for Labor     * Demand shifts when the $VMP$ of a worker changes due to:         1. Price of Output: An increase in market demand for the company's product raises the $VMP$ and shifts the labor demand curve to the right.         2. Worker Productivity: Factors increasing productivity (and thus shifting demand right) include:             * Increase in the quantity of non-labor inputs (capital).             * Organizational changes.             * Enhanced training and education.

• The Supply of Labor     * Reservation Wage: The minimum wage a worker is willing to accept for a specific job. This reflects the worker’s opportunity cost of lost leisure time.     * Work compensates for this lost leisure. If conditions are dangerous or unpleasant, the wage must include a premium.     * Supply Curve: The aggregate labor supply curve slopes upward because higher real wages incentivize more individuals to work.     * Macroeconomic Determinants of Labor Supply:         * Size of the working-age population.         * Domestic birthrate and migration (immigration/emigration).         * Ages of entry into and retirement from the workforce.         * Labor force participation rate (the share of the working-age population willing to work).     * Shifts in Supply: Caused by changes in the pool of willing workers (e.g., increased participation by women or the Baby Boom).

Explaining Labor Market Trends with Supply and Demand

• Trend 1 (Increasing Real Wages)     * Sustained growth in productivity during the $20^{\text{th}}$ century (driven by technological progress and capital accumulation) shifted the demand curve for labor to the right.     * This result was an increase in both real wages and the level of employment.

• Trend 2 (Stagnated Wage Growth Since 1970)     * The stagnation could stem from slower growth in labor demand or faster growth in labor supply.     * While slower demand growth (due to slower productivity growth) explains the stagnation, it does not account for the rapid growth in employment during this period.     * Therefore, a significant increase in labor supply must have occurred, driven by:         * High rates of immigration.         * The entry of the Baby Boom generation into the workforce.         * Increased labor force participation by women.

• Trend 3 (Increased Wage Inequality)     * Globalization: Market expansion allows for increased specialization and efficiency (Principle of Comparative Advantage). However, domestic sectors that are no longer competitive (e.g., textiles) shrink, while export sectors (e.g., software) grow.         * Demand for labor in importing industries (Textiles) shifts left (decreased wages and employment).         * Demand for labor in exporting industries (Software) shifts right (increased wages and employment).     * Skill-Biased Technological Change: Technical advancements favor higher-skilled/educated workers.         * Innovation can render old skills obsolete (e.g., computers replacing manual addition).         * Contemporary automation (e.g., robots on assembly lines) increases the demand for programmers and technicians while decreasing demand for line workers.     * These shifts result in higher wages for skilled workers and lower wages for unskilled workers, widening the gap.

Types of Unemployment and Structural Barriers

• Three Categorizations of Unemployment     * Frictional Unemployment: Occurs when workers are briefly between jobs. It is of short duration, carries low economic cost, and can lead to higher efficiency as workers find better matches.     * Cyclical Unemployment: The increase in unemployment during economic recessions or slowdowns. It is typically short-term, but its primary economic cost is the decline in real GDP.     * Structural Unemployment: Long-term, chronic unemployment that persists even in a healthy economy.         * Causes: Lack of skills, language barriers, discrimination, or long-term industry shifts (e.g., steel or telecommunications manufacturing).         * Barriers: Minimum wages, labor unions, and unemployment insurance.         * Costs: High economic, psychological, and social impacts.

• Structural Barriers and Government Regulation     * Unemployment Insurance (UI): Government transfers to those without work. While it reduces the individual cost of unemployment, it may also incentivize longer or less intense job searches.         * Effective UI systems should be limited in time and provide less income than active employment.     * Safety and Health Regulations: These can increase employer costs or reduce productivity, effectively lowering the demand for labor, which can increase unemployment and lower wages.     * Impediments to Full Employment (U.S. vs. Europe):         * European labor markets are highly regulated with high minimum wages, rigid benefits, and powerful unions.         * Combined with globalization and skill-biased tech change, these regulations make many workers "not worth employing" at the mandated rates.         * Historical Unemployment Data (1991 - 2018):             * Spain: Peaked at $22\%$ in $1995$ and $25\%$ in $2013$, ending at $15\%$             * France: Peaked at $12.5\%$ in $1995$, ending at $10\%$             * Germany: Peaked at $11\%$ in $2005$, ending at $4\%$             * UK: Peaked at $10\%$ in $1993$, ending at $5\%$             * Italy: Approximately $10\%$ in $2018$
