1、Chapter 10,Labor Unions and Collective Bargaining,1. Why Unions?,Why Unions?,Workers prior to industrial revolution were self-employed (i.e., worked for themselves). Industrialization separated the functions of management and labor. Workers became dependent on owners for employment and income. Worke

2、rs formed unions to protect their interests and bargain collectively with employers.,2. Labor Unionism: Facts and Figures,Union Membership by Industry, 2008,Unionization tends to be higher in the goods producing industries such as manufacturing and construction.,Unionization tends to be lower in ser

3、vice industries such trade and finance, real estate, and insurance.,Unionization is high in transportation, communications, and utilities due to low labor demand elasticities.,Union Membership by Occupation, 2008,White-collar workers such as managers and sales workers tend to have low unionization r

4、ates.,The low white-collar worker unionization rates are because they have higher wages and some managers are exempt from unionization.,Union Membership by Public Sector Status, 2008,Public sector workers have a much higher unionization rate than private-sector workers.,The unionization rate of publ

5、ic sector workers rose rapidly in the 1960s and 1970s when laws allowing public-sector workers to unionize were passed and public sector managers did not aggressively fight the unionization of their workers.,Union Membership by Demographic Group, 2008,High Unionization States, 2008,Low Unionization

6、States, 2008,3. Unionisms Decline,Union Membership,The unionized sector is a minority component of the labor force.,Unionism is on the decline in the U.S.,The number of union members peaked at 20 million in 1980 and has fallen to slightly more than 15 million now.,The percent of labor force that is

7、unionized fell from 30% in 1950 to 11% now.,Causes of Decline in Unionism,Structural changes The structural-change hypothesis is the labor force and economy has changed in ways that are unfavorable to unions. Employment growth has been greater in traditionally nonunion sectors such white-collar jobs

8、, services, women, small firms, part-time, and Southern states.,Causes of Decline in Unionism,The union wage differential increased in the 1970s. Unionized firms switched to nonunion methods of production where possible. Nonunion firms expanded output and employment due to their lower costs. Critici

9、sms Other countries have had similar structural changes and their unionism has not decreased. Unions have been able to unionize traditionally nonunion workers in the past.,Causes of Decline in Unionism,Managerial-opposition hypothesis The managerial-opposition hypothesis argues that the increased un

10、ion wage advantage in the 1970s caused firms to fight unions more aggressively. Firms may hire permanent strike breakers, illegally fire pro-union workers, hire consultants, etc. The number of illegal anti-union has increased.,Causes of Decline in Unionism,The substitution hypothesis The substitutio

11、n hypothesis argues that the government and employers now provide services that were previously provided by unions. The government now provides services such as workers compensation and health and safety laws that unions used to provide. Some firms try to prevent unionization by using grievance proc

12、edures and providing worker-management communication methods.,Causes of Decline in Unionism,Other factors Unions have decreased their organizing efforts. The National Labor Relations Board, which oversees unionization efforts, became less pro-union under Reagan-Bush.,Causes of Decline in Unionism,Re

13、lative importance Freeman concludes that the total decline in unionization is due to: Structural changes (40%) Increased managerial-opposition (40%) Decreased union organizing (20%) Krueger argues nearly all of the recent decline in unionization is due to decreased demand for unions among nonunion w

14、orkers.,Union Responses to Decline,Increased mergers among unions Example: NEA and AFT Changes in strategies Unions have increased organizing efforts and targeted white-collar workers. Unions have tried to avoid strikes and used work slowdowns in their place.,Questions for Thought,1. Critically eval

15、uate each of these statements:,(a) “The relative decline of the American labor movement can be explained by the shift from goods- producing to service-producing industries and the closely related shifts from blue-collar to white-collar occupations and from male to female employees.,(b) “The success

16、of unions in raising their wages relative to nonunion workers has contributed to the decline in unionism.,(c) “Unionized firms have tended to be less profitable, and therefore, employers are more resistant to unionization.,4. What Do Unions Want?,Monopoly Union Model,Economists usually assume that t

17、he goal of a union is to increase both the wages and employment of its members. Economists construct union indifference curves that show the combinations of wage and employment where the union is indifferent. Characteristics of indifference curves Negatively sloped Convex,Monopoly Union Model,The mo

18、nopoly union model assumes that the union sets the wage rate and the firm sets the level of union employment based on this wage rate. The firm maximizes profits and thus chooses an employment level based on its labor demand curve. The available wage and employment combinations for the union are on t

19、he labor demand curve.,Monopoly Union Model,Employ,Wage,0,In the monopoly union model, the utility maximizing wage and employment for the union is point u, where union indifference curve I3 is just tangent to the labor demand curve DL.,I1,I3,DL,Qu,Wu,u,The union raises the wage rate from Wc to Wu, t

20、he firm decreases employment from Qc to Qu, and the union increases total utility from I1 to I3.,c,I4,Wc,Qc,Efficient Contracts Model,Employ,Wage,0,The outcome of the monopoly union model is point u. This combination is not efficient for the two parties since at least one of them could be made bette

21、r off by moving off the labor demand curve.,I3,DL,Qu,Wu,u,The combinations of wage and employment where at least one party is better off without the other party worse off are called efficient contracts.,y,I4,Wy,Qy,P1,For example, at point y, the union has achieved a higher utility level than at poin

22、t u by being on a higher indifference curve and the firm is no worse off because it stays on the same isoprofit curve.,Efficient Contracts Model,The contract curve is composed of the set of efficient contracts (tangencies of union indifference curves and isoprofit curves). The slope of the contract

23、curve depends on the shapes of the firms isoprofit curves and the unions indifference curves. A vertical contract curve at the competitive employment level is called a strongly efficient contract curve.,Efficient Contracts Model,In general, the efficient contract outcome will result in lower wage an

24、d more employment than the monopoly union outcome. Economists have suggested this helps explain the requirements for excess labor in union contracts. These stipulations or “feather bedding” take the form of work rules specifying minimum work crew sizes or narrow job descriptions.,Empirical Evidence,

25、A direct test of the efficient contracts model is whether unions bargain over employment as well as wages. Contrary to the efficient contracts model, union contracts almost always allow firms to unilaterally set the employment level. Some researchers have suggested they may indirectly affect employm

26、ent by bargaining over capital-labor ratios.,Empirical Evidence,Indirect tests of the efficient contracts model rely on the fact that efficient contracts and monopoly union models have different predictions regarding which factors affect the level of union employment. Monopoly union predicts union e

27、mployment level should be related to the union wage, but it should have no relationship with the competitive wage. Strongly efficient contract model predicts union employment level should be related to the competitive wage, but it should have no relationship with the union wage. The findings from th

28、ese indirect tests yield mixed support for the efficient contracts model.,5. Unions and Wage Determination,Unions and Wages,Unions can increase the wages of their members by: Increasing the demand for union labor Restricting the supply of labor Bargaining for an above equilibrium wage,Increasing Lab

34、 all new hires to join the union), the union may achieve a wage WU that is above the competitive wage WC.,The effect is to make the labor supply curve perfectly elastic at WU until point d.,The employment level will fall from QC to QU.,An efficiency loss of abc will also result.,The more elastic is

35、DL, the larger is the employment loss. As result unions try to reduce the elasticity of DL.,d,Questions for Thought,1. Explain how each one of the following contract provisions might affect the elasticity of labor demand during the period of the labor contract:,(a) Layoff and severance pay,(b) Preve

Under what elasticity of labor demand conditions could a union restrict the supply of laborthat is, shift the supply curve leftwardand thereby increase the collective wage income (wage bill) of those workers still employed?,
