Employment Protection Versus Flexicurity: On Technology Adoption in Unionised Firms*

We analyse how different labour‐market institutions – employment protection versus ‘flexicurity’– affect technology adoption in unionised firms. We consider trade unions’ incentives to oppose or endorse labour‐saving technology and firms’ incentives to invest in such technology. Increased flexicurity – interpreted as less employment protection and a higher reservation wage for workers – unambiguously increases firms’ incentives for technology adoption. If unions have some direct influence on technology, a higher reservation wage also makes unions more willing to accept technological change. Less employment protection has the opposite effect, as this increases the downside (job losses) of labour‐saving technology.     

Skills,Tasks and the Scarcity of Talent in a Global Economy

The scarcity of talent is a tremendous challenge for firms in the globalized world. This paper investigates the role of labor market imperfection in open economies for the usage of talent in the production process of firms. For this purpose, I set up a heterogeneous firms model, where production consists of a continuum of tasks that differ in complexity. Firms hire low‐skilled and high‐skilled workers to perform these tasks. How firms assign workers to tasks depends on factor prices for the two skill types and the productivity advantage of high‐skilled workers in the performance of complex tasks. I study the firms’ assignment problem under two labor market regimes, which capture the polar cases of fully flexible wages and a binding minimum wage for low‐skilled workers. Since the minimum wage lowers the skill premium, it increases the range of tasks performed by high‐skilled workers, which enhances the stock of knowledge within firms to solve complex tasks and reduces the mass of active firms. In a setting with fully flexible wages trade does not affect the firm‐internal assignment of workers to tasks. On the contrary, if low‐skilled wages are fixed by a minimum wage, trade renders high‐skilled workers a scarce resource and reduces the range of tasks performed by this skill type with negative consequences for the human capital stock within firms. In this case, trade leads to higher per‐capita income for both skill types and thus to higher welfare in the open than in the closed economy, whereas – somewhat counter‐intuitive – inequality between the two skill types decreases, as more low‐skilled workers find employment in the production process.     

Efficient bargaining versus right to manage: A stability analysis in a Cournot duopoly with trade unions

The present study considers a unionised (nonlinear) duopoly with two different labour market institutions, i.e. efficient bargaining (EB) and right to manage (RTM), to analyse product market stability under quantity competition with trade unions. We show that when the preference of unions towards wages is small, (i) the parametric stability region under RTM is higher than under EB, and (ii) a rise in the union power in the Nash bargaining played between firms and unions monotonically increases (resp. reduces) the parametric stability region under RTM (resp. EB). In contrast, when the preference of unions becomes larger, an increase in the union's bargaining power acts: (1) as an economic stabiliser when the union power is small; (2) as an economic de-stabiliser when the union power is high. In addition to established results with regard to equilibrium outcomes, our findings shed some light on the effects of how the labour market regulation affects out-of-equilibrium behaviours in a Cournot duopoly.     

International outsourcing when labour markets are unionized

Abstract. We consider the implications of international outsourcing in a simple general equilibrium model where the wage rate is the outcome of negotiations between a firm and a trade union. The effects of potential, but non‐realized, international outsourcing, is a reduction in the wage rate and an increase in employment. Aggregate welfare increases, but the trade union becomes worse off while owners of capital become better off. Realized international outsourcing gives rise to an increase in the wage rate and a reduction in employment. Aggregate welfare decreases, but the trade union becomes better off, while owners of capital become worse off.     

Unemployment and product market competition in a Cournot model with efficiency wages

This paper analyzes the impact of product market competition on unemployment, wage and welfare in a model where unemployment is caused by the efficiency wage consideration and oligopolistic firms compete in quantity. It is shown that while more intense competition in the product market increases output and reduces price, it does not necessarily lead to a lower unemployment rate or a higher wage for workers. Depending on the technologies, the relationship between the intensity of competition and the level of employment (respectively, wage, welfare) is not always monotonic, and, in some instances, has an inverted U‐shape.     

The impact of trade on employment,welfare, and income distribution in unionized general oligopolistic equilibrium

This paper sets up a multi-sector general oligopolistic equilibrium trade model in which all firms face wage claims of firm-level unions. By accounting for productivity differences across industries, the model features income inequality along multiple lines, including inequality between firm owners and workers as well as within these two groups of agents, and involuntary unemployment. We use this setting to study the impact of trade liberalization on key macroeconomic performance measures. In particular, we show that a movement from autarky to free trade with a fully symmetric partner country lowers union wage claims and therefore stimulates employment and raises welfare. Whether firms can extract a larger share of rents in the open economy depends on the competitive environment in the product market. Furthermore, the distribution of profit income across firm owners remains unaffected, while the distribution of wage income becomes more equal when a country opens up to trade with a fully symmetric trading partner. We also analyze how country size differences and technological dissimilarity of trading partners affect the results from our analysis.     

Inflation and Openness with Non‐Atomistic Wage Setters

This paper analyses the impact of trade openness on inflation in a strategic framework characterised by monopolistic production in the domestic sector and unionised labour markets. By stressing the interplay between internal and external sources of economic distortion, we show that the economy's inflationary bias reduces up to a critical level of trade openness. Beyond this threshold, wage setters may be induced to behave more aggressively in open economies, leading to higher equilibrium inflation. Based on a regression analysis that investigates the combined effect of labour market institutions and openness on inflation across nineteen OECD economies, we show that inflation is negatively related to openness when wage bargaining is decentralised, while there is virtually no link between openness and inflation at higher levels of wage centralisation.     

Capital tax,minimum wage,and labor market outcomes

Often an increase in the minimum wage is accompanied by a reduction in the capital tax. This paper analyzes the effects of interactions between the minimum wage and the capital tax in the general equilibrium framework. The analysis is conducted in an inter-temporal search model in which firms post wages. A (binding) minimum wage provides a lower support for the distribution of wages. The paper finds that the interaction of these two policy instruments significantly modify labor market outcomes and welfare cost. In the presence of a binding minimum wage, a decrease in the capital tax leads to an increase in wage dispersion. In contrast, when it is not binding, a lower capital tax may reduce the dispersion in wages. A binding minimum wage magnifies the positive effects of a lower capital tax on labor supply, employment, and output. It also enhances the welfare cost of capital tax. A policy change which involves an increase in the minimum wage and a fall in the capital tax such that employment level remains constant increases welfare and output.     

Employee share ownership in a unionised duopoly

Profit sharing schemes have been analysed assuming Cournot competition and decentralised wage negotiations, and it has been found that firms share profits in equilibrium. This paper analyses a different remuneration system: employee share ownership. We find that whether firms choose to share ownership or not depends on both the type of competition in the product market and the way in which workers organise to negotiate wages. If wage setting is decentralised, under duopolistic Cournot competition both firms share ownership. If wage setting is centralised, only one firm shares ownership if the degree to which goods are substitutes takes an intermediate value; otherwise, the two firms share ownership. In this case, if the union sets the same wage for all workers neither firm shares ownership. Therefore, centralised wage setting discourages share ownership. Finally, under Bertrand competition neither firm shares ownership regardless of how workers are organised to negotiate wages.     

The determination of union and non-union wage rates

If, in a partially unionised economy, union workers force up their absolute wage rate, how does this affect the wage paid in the non-union sector? This paper suggests a simple answer. First, in a small open economy a rise in the union wage will raise the non-union wage. Secondly, in a closed economy — or one with some monopoly power in world trade — a rise in the union wage seems likely to depress the non-union wage.     

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'.     

Unemployment and the 'Labour-management Conspiracy'

We study a model in which management and a union bargain over a rule that will later determine the level of employment, and over a wage. The government then chooses an output or an employment subsidy. An exogenous natural turnover rate in the unionised sector creates unemployment whenever the union wage exceeds the competitive wage. Government intervention can increase both the equilibrium amount of unemployment and worsen the intersectoral allocation of labour, because of the induced change in the endogenous wage. Unemployment weakens but does not eliminate the possibility of a 'labour-management conspiracy'.     

The Effects of Trade Liberalization in a Vertical Structure

Despite the importance of international trade on intermediate goods, the literature did not pay much attention to this aspect in determining the effects of trade liberalization in the presence of a labor union. We take up this issue here and show the effects of trade liberalization on the final goods and/or the intermediate goods, where the domestic firm pays unionized wage and imports intermediate goods. We show that trade liberalization on the intermediate goods (final goods) increases (decreases) the unionized wage, labor union's utility and domestic profit. Trade liberalization on both the final goods and intermediate goods may either increase or decrease the domestic unionized wage, labor union's utility and domestic profit depending on the input coefficients and the initial tariff levels. Our qualitative results are robust with respect to the intermediate goods market structure, the pricing strategy of the intermediate goods producers and the union's objective function.     

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.     

Trade and inequality in a directed search model with firm and worker heterogeneity

This paper integrates the insight that exporting firms are typically more productive and employ higher‐skilled workers into a directed search model of the labour market. The model generates a skill premium as well as residual wage inequality among identical workers. A trade liberalization increases the skill premium and likely increases residual inequality among high‐skilled workers. The calibrated model generates results consistent with the prior literature examining the effect of the Canada‐US Free Trade Agreement on the Canadian labour market: a significant decrease in employment in manufacturing, but only a small change in unemployment and wages.     

Economic migration and business cycles in a small open economy with matching frictions

With the free movement of labour in Europe, economic migration has become an important determinant of labour supply. Cyclical migration exceeds one percent of the population in many countries and affects (un)employment and wage setting. The main contribution of this paper is that it models migration as an endogenous decision in a search-and-matching framework, where labour market institutions play an important role. It shows that, contrary to typical beliefs, migration can amplify business cycles. After a positive shock to the economy, immigration increases the labour force and initially unemployment. The latter reduces a worker's outside option in wage negotiations, resulting in a lower wage increase than when there is no migration. With cheaper labour firms post more job vacancies, which increases the probability that unemployed workers find jobs and attracts new workers to immigrate. Attenuated response of wages and the stronger response of employment to shocks result in a flatter Phillips curve.     

Equilibrium unemployment with outsourcing and wage solidarity under labour market imperfections

We evaluate the effects of outsourcing and wage solidarity on wage formation and equilibrium unemployment in a heterogeneous labour market, where wages are determined by a monopoly labour union. We find that outsourcing promotes the wage dispersion between the high- and low-skilled workers. When the labour union adopts a solidaristic wage policy, it will dampen this tendency. Further, higher outsourcing will increase equilibrium unemployment among the high-skilled workers, whereas it will reduce it among the low-skilled workers. Overall, outsourcing will reduce economy-wide equilibrium unemployment under the reasonable condition that the proportion of high-skilled workers is sufficiently low.     

Equilibrium Wage Dispersion,Firm Size,and Growth

This paper analyzes a model of equilibrium wage dynamics and wage dispersion across firms. It considers a labor market where firms set wages and workers use on-the-job search to look for better paid work. It analyzes a perfect equilibrium where each firm can change its wage paid at any time, and workers use optimal quit strategies. Firms trade off higher wages against a lower quit rate, and large firms (those with more employees) always pay higher wages than small firms. Non-steady-state dispersed price equilibria are also analyzed, which describe how wages vary as each firm and the industry as a whole grow over time.

Entry Deterrence in a Unionized Oligopoly

We investigate wage determination between an incumbent firm and its labour union under threat from another firm entering its product market. In equilibrium, it may be optimal for a labour union of the incumbent firm to lower its wage demand. This may make it possible for the incumbent firm to maintain a higher employment level, in that the lower wages can help the firm deter the entry of a rival firm. This will yield a higher profit for the incumbent firm and a lower utility level for the labour union compared with those in an equilibrium with no threat of entry.

Import Penetration and Domestic Process Innovation

This paper develops a model of R&D competition between domestic and foreign firms that explicitly incorporates the effect of the market structure. We focus on how differences in costs modify the effects of increases in the number of foreign firms on R&D investments of domestic firms. We show that an increase in the number of foreign firms may have a positive effect on a domestic firm's R&D investment and also show that two trade policies, tariffs or quotas, could have different effects on R&D investments of domestic firms. A welfare analysis shows that greater cost advantages increase social welfare.
