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.     

Cost‐Based Anti‐dumping as a Repeated Game

In this paper, we consider anti‐dumping (AD) duties as a tool to facilitate collusion between a domestic and a foreign firm in an infinitely repeated differentiated Bertrand game, where prices are publicly observable and each firm receives a privately observed i.i.d. cost shock in each period. We consider second‐best scenarios, where market‐share or production arrangement with sidepayments is not allowed. We show that there exist equilibrium‐path reciprocal ADs. The collusive (trigger) price is distorted downward compared with complete information benchmark as a trade‐off between diminishing the incentive to deviate and ensuring off‐schedule deviation gains when private cost shocks are highly favourable. The model differs from Green and Porter ( 1984 ) and Rotemberg and Saloner ( 1986 ) in that it is the private cost shocks as opposed to public demand shocks that necessitate modifications of collusion. In conclusion, AD policy may encourage collusion, and therefore, unless the source of market imperfection is carefully examined, laissez faire might be a better choice.     

Employment and Capital Accumulation in Unionised Labour Markets: Evidence from five south-European countries

This paper analyses the link between employment and capital accumulation in unionised labour markets by using a dynamic monopoly union model. The role of wage setting is also explored within the above context. The empirical analysis is based on annual data from the manufacturing sector of five European countries (France, Greece, Italy, Portugal and Spain). It verifies that capital accumulation has a positive influence on employment. Concerning wages, there is evidence that, in most countries, income opportunities in the public sector play an important role in wage determination. A larger public sector crowds out private investment and employment by serving as a safety net that allows wage setters to push for higher wage demands.     

Income Tax Evasion in a Unionised Labour Market

Labour market outcomes can depend on tax evasion since the returns from working are affected by the amount of taxes paid. In this paper, unionised workers are assumed to select the income which they declare. The rational trade union takes this decision into account. It is shown that the employment effects of a linear income tax are not altered qualitatively by tax evasion if the fine for evasion is a function only of the evaded tax. Moreover, the consequences of changes in the tax enforcement system are determined by the ability to choose evasion activities optimally. The existence of unrestricted tax evasion opportunities lowers wages.     

Labour Taxation in a Unionised Economy with Home Production

The impact of payroll taxes on unemployment and welfare are examined in a model with household production and union–firm wage bargaining. The analysis shows that unemployment typically falls as the payroll tax rate in the market sector for household substitutes (the service sector) is reduced. This holds even when the payroll tax rate in the non-service sector is raised in order to maintain a balanced government budget. Welfare improves with a reduced-service-sector payroll tax rate only if unions are equally strong and firms are equally labour intensive across the sectors.

Conjectural Variations and Voluntary Public Good Provision in a Repeated Game Setting

The purpose of this paper is to show how conjectural variations can be derived as a reduced form in an infinitely repeated game of private provision of public goods. We obtain explicit closed forms of conjectural variations associated with maximal sustainable equilibria in which the sum of the utilities of all of a community's members is maximized for both quadratic and Cobb–Douglas preferences, provided that the resulting sequence of contributions can be sustained as a Nash (or subgame perfect) equilibrium in the underlying repeated game. We also show that positive conjectural variations will emerge as long as people place positive weight on the future, and that those conjectures are positively related to the discount factor.     

Bankruptcy as a Control Device in Economies in Transition

We examine in this paper the design of a liquidation, or bankruptcy, policy in a partially centralized economy characterized by imperfect information. We employ a two-period model to analyze the effects of an optimal liquidation rule on the efficiency of resource allocation and choice of managerial effort when managers have private information about effort and firm productivity. First-period investment is used by the regulator to discipline the manager and to extract information. The tradeoff between disciplinary effect and information extraction might be best solved by implementing inefficient liquidation policies. Inefficiencies in liquidation policies can occur even if the regulator believes that he is facing a given type of firm with probability close to one. J. Comp. Econom., June 1995, 20(3), pp. 265-301.

Evolutionary Stability in the Finitely Repeated Prisoner 's Dilemma Game

The dynamic evolutionary stability of mutual defection is proven for the repeated prisoner 's dilemma game where payoffs are cumulative and the number of repetitions is known. This agrees with the classical result that the only Nash equilibrium outcome is to defect at all stages of this repeated game. Moreover, it is shown that, for any initial polymorphic population, the evolutionary dynamic converges to a unique Nash equilibrium strategy that depends on the original polymorphism. Both these results confirm earlier conjectures concerning the application of evolutionary game theory to the repeated prisoner 's dilemma.Journal of Economic LiteratureClassification Numbers: C70, C72.     

信誉机制在欺诈行为中的运行分析--来自一次博弈与重复博弈的解释

信誉机制是维护市场经济中行为主体交易活动正常化的基石。没有信誉机制的市场是杂乱无章的市场，同时也将伴随着行为主体利益的损失，产生一种低效的市场绩效。本文将分别用一次博弈和重复博弈模型来说明信誉机制在欺诈行为产生及其演变过程中所起的作用，并以相应的结论来说明市场中信息的透明度、信息的传播方式与手段以及政府执法的及时性、公正性等制度因素对信誉机制发挥作用的影响。     

Testing for Ongoing Convergence in Transition Economies, 1970 to 1998

In this paper, the authors use a time-varying parameters procedure to test for a common growth path in the ex-Communist bloc, both pre- and postreform. They test whether there has been convergence within the bloc or between the bloc as a group and the West. Surprisingly, there is little evidence of convergence within the bloc, which brings into question the effectiveness of policies to reduce differentials in income per capita under the Communists. There is also little evidence of convergence with respect to the West, either during the period from 1970 to 1990 or if the reform years are included (i.e., 1970 to 1998). J. Comp.

Pollution Control in Open Economies: Implications of Within-period Interactions for Dynamic Game Equilibrium

This paper examines a two-country, dynamic game model of pollution control in the presence of economic interactions between countries within a period, as well as the environmental interaction between periods (i.e., a change in the stock of global pollution). These economic interactions emerge because of changes in the terms of trade of polluting goods or the market share of domestic polluting industries. It is shown that if within-period externalities exist, a noncooperative equilibrium may result in a smaller stock of global pollution in the steady state than does international cooperation. Moreover, the properties of equilibrium paths depend on the direction and size of such externalities. In addition, trigger strategy equilibria that achieve the outcome of the collusive solution are examined.     

Exchange Rate Movements and Employment Growth: An OCA Assessment of the CEE Economies

According to the traditional optimum currency area approach, not much will be lost from a very hard peg to a currency union if there has been little reason for variations in the exchange rate in the past. This paper takes a different approach and highlights the fact that high exchange rate volatility may also signal high costs for labor markets. The impact of exchange rate volatility on labor markets in the CEECs is analyzed, revealing that volatility vis-à-vis the euro significantly lowers employment growth. Hence, eliminating exchange rate volatility could be considered a substitute for removing employment protection legislation.     

Economies with a two-sector representation

Summary In both theoretical and empirical research it is a common practice to partition the economy into (at least) two sectors in order to conduct partial-equilibrium analysis. One merely hopes that general-equilibrium consequences will not obviate all of the analysis of the sector or market in question. In this paper we consider market demand functions which have a two-sector representation. In such economies the aggregate compensated demands in any one sector depend only on prices in that sector, the vector of utilities, and a scalar aggregate which in turn may depend upon everything. In particular, prices in the other sector appear only through this aggregate. In a single-consumer economy this division into two sectors carries with it no further implications. However, when there are three or more consumers, economies with a two-sector representation, which may contain public as well as private goods, must fall into a small number of broad classes which are quite restrictive. This means that the two-sector assumption is far less innocuous than one might have previously believed and that there are some phenomena which simply cannot be investigated in this framework.This research has been supported by the SSHRCC with a research grant and by leave fellowships to all three authors for the year 1984–85.

强化知识产权保护与南北双赢

传统观点认为,强知识产权保护有利于北方国家而有损于南方国家。本文构建一个两期技术转移模型,说明在一定条件下,南方国家会自愿加强知识产权保护,并实现南北双赢。假设北方企业拥有两种技术,即传统技术和先进技术。若南方的知识产权保护太弱,北方企业可能会因为害怕被模仿而策略性延迟引入先进技术,导致南方国家受损。此时,南方政府将有积极性自愿加强知识产权保护以防止北方企业采用延迟策略,而模型分析表明,最优的知识产权保护力度是南方企业模仿能力的倒U型函数。进一步,如果是否拥有先进技术是北方企业的私人信息,南方政府将更不愿意采用严格的知识产权保护制度,因而消除信息不对称有利于南方国家自愿强化知识产权保护。     

Sustainability in Uncertain Economies

A stochastic growth model with a list of capital assets (i.e., reproducible capital, non-renewable resources, the knowledge base and institutions) is studied to evaluate the effects of different sources of uncertainty on sustainability. It is also discussed which measure can serve as an index of intergenerational welfare to evaluate sustainable development under uncertainty. The aim is to consider a more comprehensive setting than is usually explored in the literature and to generalize Arrow, Dasgupta and Mäler results to the case of uncertainty.
