Investment and technological choice in a right-to-manage model

We analyze the interactions between investment and local wage bargaining in a putty-clay model where the investment decision commits the firm to a particular capital intensity. This technological precommitment is used strategically in order to manipulate the bargaining outcome. We show that this strategic behavior induces a nonmonotonic relationship between the capital and labor demands of the firm and most of its environmental parameters (e.g., the bargaining power of the union, its minimum wage requirement, the capital cost). The results we obtain in our putty-clay framework thus contradict several conclusions of the standard literature on wage bargaining and investment.     

Relative wages, labor specialization and bargaining patterns

The goal of this paper is to study the effects of centralized and decentralized bargaining patterns on wage inequality when there are two different types of labor, skilled and unskilled. We present two models where labor is specialized between firms, that is, there are two types of firms, each one employing one type of labor. We show that the revenue shares of the production factors in each type of firm and the union power are crucial determinants of the relative wage. In contrast, the relative expected wage is the same across models and bargaining patterns.     

Trade unions vs. statistical discrimination: Theory and application to post-apartheid South Africa

A simple model of statistical discrimination is analyzed, which captures some stylized facts of the South African labor market. It shows that this type of discrimination disappears when the wage rates are determined by efficient bargaining between a representative firm and a union, with endogenous membership. This may explain why the wage gap between Black and White workers in post-apartheid South Africa is smaller among unionized workers than among non-unionized ones.     

Profit sharing as entry deterrence mechanism

In a right-to-manage framework, this paper analyzes the optimal choice of the pay scheme (profit sharing vs. fixed wage) in a unionized duopoly with potential market entry and decentralized bargaining. The paper shows that, depending on the institutional features, both pay systems can arise as equilibria in Nash strategies. Under duopoly with committed bargaining, the fixed wage is the Nash equilibrium; with flexible bargaining, an agreement between the incumbent firm and its union about profit sharing arises as Nash equilibrium, if the union is not too strong. A monopoly with threat of entry reinforces the selection of profit sharing as a deterrent mechanism.     

WAGE BARGAINING WITH A PRICE-SETTING FIRM

This paper examines the introduction of monopolistic competition into wage bargaining models: in addition to capital-labour substitution, we also consider a cost-push effect. The right-to-manage model requires strong restrictions on the objective functions and leads to problematic conclusions because the wage claims of the union are generally not compatible with the mark-up requirement contained in the firm's price equation. In the efficient bargaining model, the union negotiates also the employment level, which gives it a way of extracting part of the monopoly rent: the firm's commitment to an efficient wage-employment combination forces it to follow a pricing rule such that part of the surplus is transferred to the union.     

Entry Threats and Inefficiency in ‘Efficient Bargaining’

We study limit pricing in a model of entry with asymmetric information, where the incumbent firm's wage is endogenously determined through ‘efficient bargaining’ with its union. In the presence of entry threat, the incumbent firm‐union pair may face a conflict between rent sharing and transmitting its cost information. When the wage is not observable to outsiders and employment is the only signalling instrument, over‐employment features in all entry deterring contracts. When the wage is also observable, information transmission becomes easier. Most of the time, then, but not always, the efficient contract deters (induces) entry against the low (high) cost incumbent.     

Flexible and Committed Profit Sharing with Wage Bargaining: Implications for Equilibrium Unemployment

We analyze the relationship between profit sharing, employee effort, wage formation and unemployment under different relative timings of the wage and profit sharing decisions. The optimal profit share under commitment exceeds that under flexibility, because through a profit share commitment the firm can induce wage moderation. The negotiated profit sharing depends positively on the bargaining power of trade union and it has both effort-enhancing and wage-moderating effects. Higher profit sharing is shown to reduce equilibrium unemployment under ``sufficiently rigid' labor market institutions, but it can harm employment when labor market ``rigidities' are ``small enough'.     

INFORMATION SHARING IN UNION–FIRM RELATIONSHIPS*

Large firms often negotiate wage rates with labor unions. When they do, an ex ante agreement to share information should make it more likely that they will reach an agreement and capture the gains from trade. However, if the firm refuses to share information, the union may shade down its wage demand to increase the probability of acceptance. This reduction in the wage can increase the joint surplus of the agents and increase social welfare. As a result, there are some circumstances in which bargaining with incomplete information can be better for the agents and society than bargaining with complete information.

The political economy of public employment programs

What are the welfare implications of a political equilibrium where the choice of active labor market programs (ALMPs) have to please the employed majority? This issue is examined in an equilibrium model featuring matching frictions and worker–firm wage bargaining. It turns out that the welfare consequences depend on the nature of ALMPs and the political weight attributed to firm interests. If firm values carry little political weight and programs contribute to wage pressure, the employed will opt for excessive program activity.     

Union–Firm Interaction and the Right to Manage

In the context of price-setting oligopoly, this paper shows that there may be consensus in union–employer bargaining for limiting the scope of bargaining to determining wage levels and allowing the employer to act unilaterally when competing in the product market. A strategic commitment by each union–firm pair to a right-to-manage framework, rather than a participatory approach, may benefit the bargaining parties since this entails higher negotiated wage rates which, by dampening competition in the product market, may allow for an increase in the amount of surplus generated by the parties.     

Wage bargaining, labor-tax progression, and welfare

This paper analyzes the effect of labor-tax progression on employment and welfare in an economy with a unionized labor market. The government influences wage bargaining through its tax policies. Wages can be reduced by increasing the marginal labor-tax rate. If there are no restrictions on profit taxation, a first-best optimum with full employment is realized; this first-best optimum can always be implemented by a progressive tax schedule. If profit taxation is restricted, unemployment may arise. For this case, we show that the welfare-maximizing degree of tax progression is influenced by a variety of factors, in particular the wage elasticity of labor demand, the distribution of bargaining power, and the existence of unemployment benefits. Examples are given for both progressive and regressive tax structures. Comparative-static analysis reveals that a decline in union bargaining power, an increase in unemployment benefits, and an increase in the overall work force reduce the efficient degree of tax progression.     

Can domestic unions gain from offshoring?

This paper considers a unionised monopolistic firm producing a final good with isoelastic demand by using two intermediate commodities, one of which can be either imported from a low-wage country or bought from domestic subcontractors. The paper shows that, notwithstanding wage moderation, the union is better off when the firm chooses offshoring rather than domestic sourcing. The firm is the less likely to choose offshoring the more wage-oriented is the union and the higher is the union bargaining power in the wage negotiation.     

Wage Bargaining, Inventories, and Union Legislation

This paper analyses a strategic bargaining game where the firm may or maynot be able to sell out of its inventory of finished goods during astrike. Firms and the union are both risk neutral and have the same discountrate. It is shown that the wage equilibrium corresponds to the axiomaticNash bargaining solution where the threatpoints are the agents' payoffsshould bargaining continue indefinitely. We use the 1980 and 1982 EmploymentActs to test this theory, interpreting that legislation change as changingthe firm's threatpoint but not its bargaining power. This allows us toidentify the value of the firm's threatpoint post-1982. Formal testssupport the theory. Also consistent with the theory, it is found that unionwages decrease with inventories after 1982, but not before, and that theunion wage gap is smaller after 1982.     

Unions and Efficient Training

The paper examines the optimal level of training investment when trained workers are mobile, wage contracts are time-consistent, and training comprises both specific and general skills. The firm has ex post monopsonistic power that drives trained workers' wages below the social optimum. The emergence of a trade union bargaining at the firm-level can increase social welfare, by counterbalancing the firm's ex post monopsonistic power in wage determination. Local union-firm wage bargaining ensures that the post-training wage is set sufficiently high to deter at least some quits, so that the number of workers the firm trains is nearer the social optimum     

WAGE BARGAINING AND MERGER INCENTIVES WITH ASYMMETRIC COSTS

This paper examines how wage bargaining within each firm influences the relationship between an equilibrium ownership structure and the most preferred ownership structure from the viewpoint of social welfare, in a unionized oligopoly of asymmetric firms with respect to productivity of capital. We consider the merger incentive of each firm’s owner when the wage level is determined through bargaining between the firm’s owner and union. We derive a condition for both the degree of cost asymmetry among existing firms and the relative bargaining power of each firm’s owner to her/his union such that each ownership structure can be observed in equilibrium. We also show that although the two types of ownership structures with the merger involving the least efficient firm can be equilibria and socially optimal, these structures are observed only when both the degree of cost asymmetry and the relative bargaining power of each firm’s owner are moderate. Finally, we analyse the relationship among the cooperative game approach employed in this paper and two non‐cooperative merger formation approaches, and examine the robustness of the results obtained in this paper against the change in the assumption regarding each firm’s cost function.     

Strategic union delegation and strike activity

Abstract.  We develop a model of wage determination with private information, in which the union has the option to delegate the wage bargaining to either surplus‐maximizing delegates or to wage‐maximizing delegates (such as senior union members). We show that the wage outcome in case of surplus‐maximizing delegates is not necessarily smaller than the wage outcome in case of wage‐maximizing delegates, even when the wage bargaining with private information is close to one with complete information. However, if it is commonly known that the union is stronger than the firm and the demand is sufficiently elastic, then delegating to wage‐maximizing delegates definitely increases the wage at equilibrium. The maximum delay in reaching an agreement is greater whenever the union chooses wage‐maximizing delegates instead of surplus‐maximizing delegates and remains finite even when the period length shrinks to zero.

Union–firm bargaining: Order of play and efficiency

This paper shows that a modified alternating offers Rubinstein model can provide a Pareto superior outcome in the context of the right-to-manage union–firm bargaining. Two examples of bargaining protocols that yield a superior outcome are provided. In the first example, the parties engage in a game in which the order of play is determined as part of the bargaining. We show that the game has a unique subgame perfect equilibrium in which the firm always moves first in the wage bargaining game. The equilibrium wage is, therefore, unique. In the second example, we examine a two-part-tariff alternating offers bargaining protocol, where the parties bargain over the wage and transfer payments. We show that this bargaining protocol has a Pareto efficient, unique subgame perfect equilibrium. Thus, although the parties do not bargain over the level of employment, the outcome under this protocol is, nevertheless, socially optimal.     

The labor market effects of trade union heterogeneity

Empirical evidence suggests that the bargaining power of trade unions differs across firms and sectors. Standard models of unionization ignore this pattern by assuming a uniform bargaining strength. In this paper, we incorporate union heterogeneity into a Melitz (2003) type model. Union bargaining power is assumed to be firm-specific and varies with firm productivity. This framework allows us to re-analyze the labor market effects of (i) a symmetric increase in the bargaining power of all unions and (ii) trade liberalization. We show that union heterogeneity unambiguously reduces the negative employment effects of stronger unions. Firm-specific bargaining power creates a link between unionization and the entry and exit of firms, implying a reduction of the unions' expected bargaining power. Moreover, union heterogeneity constitutes an (un)employment effect of trade liberalization. If unions are most powerful in the high-productivity (low-productivity) firms, trade liberalization will increase (decrease) unemployment.     

Counter intuitive results in a simple model of wage negotiations

Summary. Short-term contracts and exogenous productivity growth are introduced in a simple wage bargaining model. The equilibrium utilities corresponding to militant union behaviour are independent of the contract length. Necessary and sufficient conditions for monotonic convergence to a unique steady state are derived. Otherwise, cyclic behaviour of wage shares is inevitable. A wage decrease can occur if strike is credible, but never when strike is not credible. In the limit, as time between bargaining rounds vanishes, this paradox survives.
