Internal labor market A firm uses an internal labor market if: external hiring is used primarily for entry-level jobs, and higher level positions are filled by promotion from within the firm.

Internal labor market reduces hiring and training costs, Internal labor markets exist because the use of such markets: reduces hiring and training costs, improves employee morale and motivation, and reduces the effect of uncertainty.

Primary vs. Secondary labor markets primary labor market - high wages and stable employment relationships. secondary labor market - low wages and unstable employment relationships.

Labor force and unemployment labor force = noninstitutionalized individuals aged 16 or above who are either working or actively seeking work. unemployed = those who are not working but are “actively seeking work”

Unemployment rate Discouraged workers are workers who have given up looking for work. An increase in the number of discouraged workers causes the unemployment rate to fall.

Labor force participation rate the labor force participation rate rises during an expansion and falls during a recession. fluctuations in the labor force participation rate over the course of the business cycle dampen cyclical fluctuations in the unemployment rate.

Trend in unemployment rates unemployment rates in the latter half of the 20th century were higher than in the first half

Trends in labor force participation rates the labor force participation rate has declined for males (primarily for males in their early 20s and over 62). the labor force participation rate has increased for females (particularly for married females).

Sectoral shifts in employment primary sector (agricultural) employment has declined as a share of the labor force, secondary sector (industrial) employment has declined slightly as a share of the labor force, but only in the past few decades, and tertiary sector (service sector) employment has increased as a share of the labor force.

Reasons for the shifts in employment the primary sector (agriculture) is characterized by rapid growth in labor productivity and a low income elasticity of demand, the secondary sector is characterized by rapid growth in labor productivity and a moderately high income elasticity of demand, and the tertiary sector is characterized by slow growth in labor productivity and a high income elasticity of demand.

Nominal and real wages Nominal wages are not adjusted for inflation and are said to be expressed in terms of “current dollars.” Real wages are wages that have been adjusted to take into account the effect of inflation. Real wages are expressed in terms of dollars from a given base year and are said to be expressed in “constant dollars.”

Wages, earnings, total compensation, and income wage = payment per unit of time earnings = wage x hours total compensation = earnings + fringe benefits fringe benefits = payments-in-kind + deferred compensation income = total compensation + unearned income (or income = earnings + unearned income)

Demand for labor The labor demand curve is downward sloping due to: a substitution effect, and a scale effect.

Substitution effect substitution effect - substitution of other resources for a resource that becomes relatively more expensive.

Scale effect The scale effect associated with a wage increase involves the following steps: higher wages result in higher average and marginal costs of production, leading to an increase in the equilibrium price of the product, leading to a reduction in the quantity of the product demanded, leading to a reduction in the use of all inputs used to produce the product.

Slope of labor demand curve Both the substitution and scale effects result in a reduction in the quantity of labor demanded when the wage rate rises. A change in the wage changes the quantity of labor demanded, but does not affect labor demand. Labor demand changes only if the labor demand curve shifts in some manner (as discussed below).

Shifts in labor demand the demand for the product, and Labor demand may shift due to changes in: the demand for the product, and the prices of other resources.

Industry demand for labor An industry's demand for labor consists of the total demand for a particular type of worker in a given industry. (An industry consists of all of the firms that produce a given type of output.) An industry's labor demand curve is determined by adding together the labor demand curves for all of the firms in the industry.

Market demand for labor The market for a given category of labor consists of all of the firms that might hire a given type of labor, regardless of the industry in which the firm operates. The market demand for labor is determined by adding together all of the industry demand for labor curves.

Long-run vs. short-run labor demand

Market labor supply The market labor supply curve is expected to be upward sloping because an increase in the wage in a particular labor market will: cause some workers in this market to work additional hours, induce some workers to shift from other labor markets to this relatively more remunerative alternative employment, and will cause some individuals who are not currently in the labor force to enter this market.

Market labor supply

Shifts in market labor supply curve Shifts such as this may be due to: changing wages in other markets, or changes in worker tastes and preferences

Labor supply to individual firms

Labor market equilibrium

Shifts in labor market equilibrium an increase in labor demand results in an increase in both the equilibrium wage and the equilibrium level of employment, a reduction in labor demand results in a decrease in both the equilibrium wage and the equilibrium level of employment, an increase in labor supply results in a lower equilibrium wage, but a higher equilibrium level of employment, and a reduction in labor supply results in a higher equilibrium wage, but a lower equilibrium level of employment.

Two types of unions industrial union trade union (also known as a craft union)

Collective bargaining agreement

Supply restriction

Overpaid and underpaid workers economists argue that workers are overpaid if their wage is above the equilibrium, workers are underpaid if their wage is below the equilibrium wage.

Economic rent Workers receive economic rent when they receive a payment that exceeds the opportunity cost of supplying their labor. The opportunity cost of supplying labor is the value of this time in its next-best alternative use. Another name for this opportunity cost is the "reservation wage," the lowest wage offer an individual will accept.

International comparisons of unemployment rates As your text notes, unemployment rates have, in recent decades, generally been higher in Europe than in the United States. It is argued that this is because nonmarket forces are more important in wage setting in Europe.
