Wage Bargaining with On‐the‐Job Search: Theory and Evidence

Most applications of Nash bargaining over wages ignore between‐employer competition for labor services and attribute all of the workers' rent to their bargaining power. In this paper, we write and estimate an equilibrium model with strategic wage bargaining and on‐the‐job search and use it to take another look at the determinants of wages in France. There are three essential determinants of wages in our model: productivity, competition between employers resulting from on‐the‐job search, and the workers' bargaining power. We find that between‐firm competition matters a lot in the determination of wages, because it is quantitatively more important than wage bargaining à la Nash in raising wages above the workers' “reservation wages,” defined as out‐of‐work income. In particular, we detect no significant bargaining power for intermediate‐ and low‐skilled workers, and a modestly positive bargaining power for high‐skilled workers.     

An Equilibrium Theory of Learning,Search, and Wages

We examine the labor market effects of incomplete information about the workers' own job‐finding process. Search outcomes convey valuable information, and learning from search generates endogenous heterogeneity in workers' beliefs about their job‐finding probability. We characterize this process and analyze its interactions with job creation and wage determination. Our theory sheds new light on how unemployment can affect workers' labor market outcomes and wage determination, providing a rational explanation for discouragement as the consequence of negative search outcomes. In particular, longer unemployment durations are likely to be followed by lower reemployment wages because a worker's beliefs about his job‐finding process deteriorate with unemployment duration. Moreover, our analysis provides a set of useful results on dynamic programming with optimal learning.     

EQUILIBRIUM SEARCH UNEMPLOYMENT,ENDOGENOUS PARTICIPATION,AND LABOR MARKET FLOWS

The sustainability of welfare states requires high employment and high participation to raise the tax base. To analyze labor supply in a world with market frictions, we propose and solve a macro model of the labor market with unemployment and labor force participation as endogenous and distinct states. In our world, workers' decisions of participating are determined by an entry decision and an exit decision. A calibration of the model improves the usual representations of labor markets, since it quantitatively accounts for the observed flows between employment and nonparticipation. The paper investigates also the effect of payroll taxes and unemployment benefits on participation decisions. Taxes reduce entries and increase exits, whereas unemployment benefits, at a given job‐finding rate, raise entries and have ambiguous effects on exits. (JEL: J2, J6)     

Psychosocial safety climate,psychosocial and physical factors in the aetiology of musculoskeletal disorder symptoms and workplace injury compensation claims

Causal agents for workers' compensation claims and physical injury have largely been identified as physical demands. We proposed an integrated theory of physical injury (i.e. musculoskeletal disorder symptoms [MSDs]) and workers' compensation claims, which combined psychosocial and physical mechanisms. A random, population-based sample of 1095 Australian workers completed a telephone interview on two occasions 12 months apart. As expected, the physical mechanism was confirmed; physical demands were related to MSDs, which in turn predicted workers' compensation claims. Further, a novel psychosocial mechanism was confirmed. Psychosocial safety climate (PSC; perceptions about the organisation's climate for psychological health) was a precursor to psychosocial risks (e.g. harassment, violence, bullying and work pressure). In turn, these psychosocial risks were related to emotional exhaustion, MSDs and then workers' compensation claims. Evidence was therefore provided for psychosocial-physical processes in explaining MSDs and workers' compensation for claims for physical injury. Occupational health and safety legislators and policy makers should be aware that, beyond physical demands, factors usually associated with risk for mental stress claims (e.g. harassment, bullying, and violence) may additionally manifest in physical health problems and workers' compensation injury claims. Focusing on modifying the PSC in an organisation, “the cause of the causes”, may be an effective injury prevention and intervention strategy.     

The Influence of Cost and Quality Priorities on the Propensity to Outsource Production*

Outsourcing of production has escalated over the past decade due to unprecedented competition and worldwide access to low‐cost labor markets. This article examines how cost and quality priorities—two key attributes of manufacturing strategy—influence a manufacturer's propensity to outsource. By doing so, we bridge the existing gap between research on manufacturing strategy and firm boundaries. We develop a theory‐based model that links a manufacturer's cost and quality priorities to its plans to outsource production. Our empirical analyses, based on survey data obtained from 867 manufacturing business units, control for firm‐specific factors previously shown to impact outsourcing, including asset specificity, uncertainty, and current capabilities in cost and quality. We found that the competitive priority placed on cost played an integral role in sourcing decisions, while, surprisingly, conformance quality priorities did not. The cost result is consistent with our expectations and observations in practice. The significant effect of cost priority on outsourcing shows that any theory of firm boundaries that fails to consider competitive priorities is incomplete. The finding regarding quality, which was counter to our expectations, may partially explain why there is an emergence of so many nonconforming products associated with outsourcing. Taken together, our results provide theoretical insights for future research into how manufacturing managers can improve their decision making on outsourcing production.     

A Theory of the Firm with Non‐binding Employment Contracts

This paper examines an employment relation in which individual workers enjoy some bargaining power vis‐a‐vis the firm although they are not unionized. The main elements of the situations studied here are that the employment contracts are non‐binding across periods of production and that the firm has opportunities to replace workers. The paper analyzes a dynamic model in which the processes of contracting and recontracting between the firm and its workers are intertwined with the dynamic evolution of the firm's workforce. The analysis of the model is somewhat complicated because the employment level is a nondegenerate state variable that evolves over time and is affected by past decisions. The main analytical results characterize certain important equilibria: the profit maximizing and stationary equilibria. The unique stationary equilibrium is markedly inefficient: it exhibits inefficient over‐employment and the steady state wages coincide with the workers' reservation wage. It confirms earlier results derived by Stole and Zwiebel (1996a, b) in the context of a static model and shows that they are very robust even when the firm has nearly frictionless hiring opportunities. In contrast, in the profit maximizing equilibrium the outcome is nearly efficient and the wage exhibits a mark‐up over the reservation wage.     

An Assessment of the Italian 2007 Complementary Social Security Reform: A Simulation Approach

In this paper we aim at assessing the outcomes of the 2007 Italian reform of the complementary social security scheme and at identifying the determinants behind them. The reform provided workers with relevant incentives to switch the investment of about 7 per cent of their gross yearly wages from a firm‐managed scheme (which took the form of a termination indemnity payment, the Trattamento di Fine Rapporto scheme) to an external pension fund. We provide a theoretical framework to model the workers' problem of choosing between these two different forms of complementary social security schemes and we then perform an agent‐based simulation taking into account all the details of the reform. Differently from previous contributions, we stress the impact that the investment decision has on the financial health of firms and, consequently, on workers' employment stability. Our simulations are able to replicate the Italian data in terms of adhesion rates to complementary social security and also to identify some of the key determinants of that outcome, such as fiscal incentives, individual preferences, the working of both the Italian labour and the financial markets and the productive structure of the Italian economy.     

The Impact of Uncertainty Shocks

Uncertainty appears to jump up after major shocks like the Cuban Missile crisis, the assassination of JFK, the OPEC I oil‐price shock, and the 9/11 terrorist attacks. This paper offers a structural framework to analyze the impact of these uncertainty shocks. I build a model with a time‐varying second moment, which is numerically solved and estimated using firm‐level data. The parameterized model is then used to simulate a macro uncertainty shock, which produces a rapid drop and rebound in aggregate output and employment. This occurs because higher uncertainty causes firms to temporarily pause their investment and hiring. Productivity growth also falls because this pause in activity freezes reallocation across units. In the medium term the increased volatility from the shock induces an overshoot in output, employment, and productivity. Thus, uncertainty shocks generate short sharp recessions and recoveries. This simulated impact of an uncertainty shock is compared to vector autoregression estimations on actual data, showing a good match in both magnitude and timing. The paper also jointly estimates labor and capital adjustment costs (both convex and nonconvex). Ignoring capital adjustment costs is shown to lead to substantial bias, while ignoring labor adjustment costs does not.     

Effect of Quality Management Systems and Total Quality Management on Productivity Before and After: Empirical Evidence from the Indian Auto Component Industry

We study the linkages between firm‐level quality initiatives such as quality management systems (QMS) and total quality management (TQM) and output productivity in the Indian auto component industry. We use externally validated quality certification and quality awards as proxies for QMS and TQM, respectively, as it is difficult to directly measure the QMS and TQM efforts of firms. We use an unbalanced panel of 220 firms and a balanced panel of 73 firms from the Indian auto component industry over the period 1993–2006 to study these links. Both parametric as well as non‐parametric approaches are used, as appropriate, to measure the rate of change in productivity and the impact of quality initiatives on productivity change during this period. We determine the proportion of productivity resulting from technical change and relative efficiency change, thus providing insights into the structure of productivity improvements. We find that TQM efforts resulted in a high rate of productivity change (11%) in the award‐winning firms after the award. On the other hand, pre‐certification productivity change due to QMS was 5% and post‐certification change was 3.6%. In the periods prior to certification, productivity change was driven mainly by technical change; whereas the source of productivity change after certification is mixed. However, prior to awards, productivity change was driven mainly by relative efficiency change, whereas post‐award productivity change was due to technical change. The results suggest that management focus on attaining certification did generate conceptual learning (linked to technical change) during the period leading to certification, but these effects were not significant after certification. The results also suggest that the TQM programs generated significant productivity gains in the long run, although setting the associated systems in place did not result in significant productivity change prior to winning awards. Thus, the study provides direct but nuanced evidence linking quality certification as well as the adoption of TQM programs to the associated conceptual and operational learning processes and their impact on the change in productivity.     

The Impact of Trade on Intra‐Industry Reallocations and Aggregate Industry Productivity

This paper develops a dynamic industry model with heterogeneous firms to analyze the intra‐industry effects of international trade. The model shows how the exposure to trade will induce only the more productive firms to enter the export market (while some less productive firms continue to produce only for the domestic market) and will simultaneously force the least productive firms to exit. It then shows how further increases in the industry's exposure to trade lead to additional inter‐firm reallocations towards more productive firms. The paper also shows how the aggregate industry productivity growth generated by the reallocations contributes to a welfare gain, thus highlighting a benefit from trade that has not been examined theoretically before. The paper adapts Hopenhayn's (1992a) dynamic industry model to monopolistic competition in a general equilibrium setting. In so doing, the paper provides an extension of Krugman's (1980) trade model that incorporates firm level productivity differences. Firms with different productivity levels coexist in an industry because each firm faces initial uncertainty concerning its productivity before making an irreversible investment to enter the industry. Entry into the export market is also costly, but the firm's decision to export occurs after it gains knowledge of its productivity.     

基于可持续性消费的企业质量价格决策研究

随着可持续性消费理念的普及,消费者愿意为可持续性生产的产品支付更高的价格,这种绿色商品溢价能快速传导到价值链上游,进而推动绿色产业升级。本文在信息非对称环境下建立了一个可持续性制造型企业及其消费者组成的供应链模型,研究可持续性消费者比例与可持续性偏好对企业质量价格决策的影响。研究结论如下：在完全信息下,当企业只服务可持续消费者时,企业的收益随可持续性消费者比例递增;在信息非对称时,可持续性消费者比例越大,企业分离时所付出的成本越高,因此可持续性投入高的企业越倾向于混同而不是分离。另外,消费者的可持续性偏好对企业来说总是有利的。但是信息非对称时,可持续性消费者比例越高,并不总是对企业有利。     

A MARKET UTILITY‐BASED MODEL FOR CAPACITY SCHEDULING IN MASS SERVICES

Only a small set of employee scheduling articles have considered an objective of profit or contribution maximization, as opposed to the traditional objective of cost (including opportunity costs) minimization. In this article, we present one such formulation that is a market utility‐based model for planning and scheduling in mass services (MUMS). MUMS is a holistic approach to market‐based service capacity scheduling. The MUMS framework provides the structure for modeling the consequences of aligning competitive priorities and service attributes with an element of the firm's service infrastructure. We developed a new linear programming formulation for the shift‐scheduling problem that uses market share information generated by customer preferences for service attributes. The shift‐scheduling formulation within the framework of MUMS provides a business‐level model that predicts the economic impact of the employee schedule. We illustrated the shift‐scheduling model with empirical data, and then compared its results with models using service standard and productivity standard approaches. The result of the empirical analysis provides further justification for the development of the market‐based approach. Last, we discuss implications of this methodology for future research.     

When are acquisitions a viable catch-up strategy? Some empirical evidence from China

How emerging-market firms can catch up with forerunners from advanced economies is a key issue in the economic and technology literature. Research has suggested that acquisitions are a viable tool for firms in emerging markets to reduce the productivity gap with global leaders, but the empirical evidence on this matter is still far from conclusive. Contributing to this debate, this paper examines the impact of cross-border vs. domestic acquisitions on the labor productivity of firms across different sectoral environments. Studying the acquisitions pursued by Chinese listed firms over one decade, we find that cross-border acquisitions are positively associated with firms' labor productivity and that this effect is particularly strong in high-tech sectors and among leading firms. We also find that domestic acquisitions are positively associated with firms’ labor productivity and that this effect is particularly strong in low-tech sectors and among laggards. We further investigate the mechanisms underlying the acquisition–productivity link and contend that “technological innovation” is the primary mechanism by which acquisitions enhance firm productivity in high-tech sectors, whereas “enhancing operating efficiency” is the primary mechanism by which acquisitions enhance firm productivity in low-tech sectors.     

Equilibrium Labor Turnover,Firm Growth,and Unemployment

This paper considers equilibrium quit turnover in a frictional labor market with costly hiring by firms, where large firms employ many workers and face both aggregate and firm specific productivity shocks. There is exogenous firm turnover as new (small) startups enter the market over time, while some existing firms fail and exit. Individual firm growth rates are disperse and evolve stochastically. The paper highlights how dynamic monopsony, where firms trade off lower wages against higher (endogenous) employee quit rates, yields excessive job‐to‐job quits. Such quits directly crowd out the reemployment prospects of the unemployed. With finite firm productivity states, stochastic equilibrium is fully tractable and can be computed using standard numerical techniques.     

COMPETITIVE MARKETS WITH ENDOGENOUS HEALTH RISKS

We study an economy where agents' productivity and labor endowment depend on their health status, and indivisible occupational choices affect individual health distributions. We show that Pareto efficiency requires cross‐transfers across occupations. Moreover, workers with relatively less safe jobs must get positive transfers whenever labor supply is not very reactive to wages, a condition in line with the findings of a large empirical literature. In these instances, compensating wage differentials equalizing the utilities of ex‐ante identical workers in different jobs undermine ex‐ante efficiency. Moreover, competitive equilibria where only assets with deterministic payoffs are traded are not first‐best. Finally, we show that simple transfer schemes, implemented through linear subsidies to health insurance, enhance efficiency.     

Tasks and Types: An Application of Mechanism Design to Self-Selection in Labour Markets

The Baron–Myerson (1982) regulatory mechanism is applied to the screening activity of a monopolist, who hires workers differentiated by quality and assigns them to different tasks. The employer charges a price to the workers for the screening service: necessary and sufficient conditions are provided for a self-selective price function to exist. It is shown that under the optimal price function tasks are assigned in such a way that workers' effort is increasing in workers' quality. It is not necessarily true, however, that the price function must be increasing in workers' quality. A simple two-types model is provided, showing the same results. Also the extension of the model to a dynamic context and, particularly, the requirements of a credible pre-commitment available to the screener are discussed.     

Profit Sharing and the Firm‐Size Wage Premium

This study analyzes the relationships among wages, firm size, and profit sharing schemes. We develop a simple theoretical model and explore the relationship empirically using high‐quality panel data. The theoretical model shows that the firm‐size wage premium decreases in the presence of profit sharing. The empirical results based on rich matched employee‐employer data for private sector wage earners in Finland show that the firm‐size wage premium is modest, and it becomes negligible when we account for profit sharing and covariates describing assortative matching and monopsony behavior. The analysis suggests that profit sharing schemes embody effects of firm‐specific unobservables that raise productivity, support rent sharing, and boost wages.     

The Economic Value of a Sustainable Supply Chain

The economic rationale to operate a global supply chain in a sustainable manner is developed. Arguments are made based on marketing, finance, and production theories that by engaging in socially responsible behavior the firm will increase sales, decrease costs, reduce financial risk, and increase profits, which will ultimately increase returns to the firm's shareholders. A model is developed of the mechanism by which modern production methods such as lean production and quality management result in sustainable corporate behavior that, in the long run, translates into higher stock valuations. The production effects cause marketing and financial risk effects that are complementary, and all three channels of influence synergistically result in higher stock values in the model. These effects also provide important benefits to other stakeholders of the firms including employees, customers, the environment, and the community. An important ethical issue in global supply chains is working conditions in foreign plants often leading to allegations of sweatshop labor conditions. This issue is used to illustrate how lean production practices can affectconsumers, employees, and financial risk. Conclusions from the sweatshop labor issue are shown to apply to other sustainability issues as well.     

Optimal Pricing of Two Successive‐Generation Products with Trade‐in Options under Uncertainty

To entice consumers to purchase both current and next generation products, many manufacturers and retailers offer trade‐in programs that allow buyers of the first generation product to trade‐in the product and purchase the new generation product at a lower price. By considering the interactions between “forward‐looking” consumers and a firm when a trade‐in program is offered, we analyze a two‐period dynamic game to determine the optimal prices of two successive‐generation products in equilibrium, and examine the conditions under which trade‐in programs are beneficial to the firm. Our model incorporates market heterogeneity (valuation of the first generation product varies among the consumer population), product uncertainty (the incremental value of the new product is uncertain before its introduction), and consumers' forward‐looking behavior (consumers take future product valuation and prices into consideration when making purchasing decisions). With the trade‐in option, we show that consumers are willing to pay a price that is higher than their valuations of the current product. Furthermore, trade‐in programs are more beneficial to the firm when: (i) the durability of the current product is high; (ii) the market heterogeneity is low; or (iii) the uncertainty level (or the expected incremental value) of the new product is high. Finally, when the incremental value of the new product is more uncertain, consumers are more willing to purchase the current product because of the “option” value of the trade‐in programs and thus trade‐in programs can be more beneficial to the firm in this case.     

Open Source Development with a Commercial Complementary Product or Service

We examine optimal control decisions regarding pricing, network size, and hiring strategy in the context of open source software development. Opening the source code to a software product often implies that consumers would not pay for the software product itself. However, revenues may be generated from complementary products. A software firm may be willing to open the source code to its software if it stands to build a network for its complementary products. The rapid network growth is doubly crucial in open source development, in which the users of the firm's products are also contributors of code that translates to future quality improvements. To determine whether or not to open the source, a software firm must jointly optimize prices for its various products while simultaneously managing its product quality, network size, and employment strategy. Whether or not potential gains in product quality, network size, and labor savings are sufficient to justify opening the source code depends on product and demand characteristics of both the software and the complementary product, as well as on the cost and productivity of in‐house developers relative to open source contributors. This paper investigates these crucial elements to allow firms to reach the optimal decision in choosing between the open and closed source models.
