Market frictions and the competitive advantage of internal labor markets

Research summary : We show that frictions in labor and capital markets can be a source of competitive advantage for affiliates of corporate groups over stand‐alone firms in environments where benefits from internal markets' flexibility are high. We argue that the advantage of flexibility in changing labor inputs is related to how difficult it is to change capital inputs. We predict that if substituting labor with capital is difficult, the group advantage of flexibly changing labor would be stronger in countries with high levels of financial development. Consistent with this prediction, we find a stronger competitive advantage for group affiliates in countries with rigid labor markets but flexible capital markets. In these environments, group affiliates are more prevalent and outperform stand‐alone firms in terms of growth and profitability. Managerial summary : This research shows that the capacity to redeploy workers across internal units of the firm can be a source of competitive advantage in countries that impose strict employment protection laws. We show that the strategic advantage of labor flexibility is affected by how difficult it is to change capital inputs and that labor flexibility is a stronger source of competitive advantage in countries where developed financial markets allow for more flexible capital adjustment. In these settings, strategies designed to lower costs of internal mobility (e.g., locations of greater geographic concentration between units and in regions with less competitive external markets), development of corporate culture supportive of frequent change, and personnel development through internal rotation can result in substantial financial payoffs.

Temporary Employment and Strategic Staffing in the Manufacturing Sector

While prior research has identified different ways of using temporary workers to achieve numerical flexibility, quantitative analysis of temporary employment has been limited to a few key empirical indicators of demand variability that may confound important differences. Our analysis provides evidence that many manufacturers use temporary workers to achieve what we call planned and systematic numerical flexibility rather than simply in a reactive manner to deal with unexpected problems. Although temporary work may provide many benefits for employers, a key function appears to be the provision of numerical flexibility not to buffer core workers but to externalize certain jobs.     

Union Strategies,National Institutions and the Use of Temporary Labour in Italian and US Plants

This article analyses variation in the use of temporary labour based on a comparison of two plants of the same US automotive multinational corporation, one in Italy and the other in the United States. We argue that differences in the use of temporary labour are explained by union capacities to make trade‐offs between alternative forms of flexibility as well as trade‐offs in the protection of internal and external groups of workers. Union capacity is dependent on the availability of power resources within different national institutional environments. These resources are shown to influence not only the ways in which temporary workers are used but also bargaining outcomes — including employment conditions — benefiting them.     

Budget allocation for permanent and contingent capacity under stochastic demand

We develop a model of budget allocation for permanent and contingent workforce under stochastic demand. The level of permanent capacity is determined at the beginning of the horizon and is kept constant throughout, whereas the number of temporary workers to be hired must be decided in each period. Compared to existing budgeting models, this paper explicitly considers a budget constraint. Under the assumption of a restricted budget, the objective is to minimize capacity shortages. When over-expenditures are allowed, both budget deviations and shortage costs are to be minimized. The capacity shortage cost function is assumed to be either linear or quadratic with the amount of shortage, which corresponds to different market structures or different types of services. We thus examine four variants of the problem that we model and solve either approximately or to optimality when possible. A comprehensive experimental design is designed to analyze the behavior of our models when several levels of demand variability and parameter values are considered. The parameters consist of the initial budget level, the unit cost of temporary workers and the budget deviation penalty/reward rates. Varying these parameters produce several trade-offs between permanent and temporary workforce levels, and between capacity shortages and budget deviations. Numerical results also show that the quadratic cost function leads to smooth and moderate capacity shortages over the time periods, whereas all shortages are either avoided or accepted when the cost function is linear.     

From Core to Periphery? Recent Developments in Employment Relations in the Philippines

We seek to describe recent developments in employment relations in the Philippines, placing these developments in the contexts of the distinctive elements of the Philippine social/political/industrial relations systems as well as the ongoing trade-based and functional integration of international markets and the recent regional economic crisis. We find that while some firms are pursuing functional flexibility and more cooperative employment relations, the logic of competition primarily has induced firms to adopt practices that promote numerical flexibility such that a core-periphery workforce is created. We argue that the labor movement in the Philippines has been hampered in its efforts to effectively counter employer strategies by its low density and fragmentation and an unfavorable public-policy environment; Philippine labor unions have, however, made some recent gains in organizing and interunion coordination. We also argue that the government has not done enough to counteract the negative effects of market integration on workers nor to evolve th e Philippines into a higher-value-added exporter.     

Transitions into Permanent Employment in Spain: An Empirical Analysis for Young Workers

This article analyses the transitions into permanent employment of a sample of young temporary employees in Spain for the period 1996–2003. For this purpose, we apply multiple‐spell duration techniques to a longitudinal dataset of temporary workers obtained from Social Security registers. Our main findings are as follows. First, the transitions from a temporary contract into unemployment and into another temporary contract are very high when compared with transitions into permanent employment. Second, the entry into permanent employment — although slightly increasing with tenure at the temporary contract — is very low; the only exception is that of semi‐skilled and unskilled individuals, who are particularly likely to enter into permanent employment at the 24th and the 36th month of tenure (respectively). Third, we find that there exists a substantial proportion of workers with unobservable characteristics that make them show high exit rates from temporary employment and, at the same time, a rapid exit from unemployment — while the remaining individuals exit from unemployment more slowly, particularly those who are receiving unemployment benefits.     

Does the digital economy generate a gender dividend for female employment? Evidence from China

Using data from the China General Social Survey, the China Family Panel Studies, and a unique dataset of enterprises' online recruitment, this research examines the effect of the digital economy on female employment. The empirical results suggest that the digital economy significantly promotes female employment. Consistent with our theoretical analysis, the estimates indicate that this relationship holds because the digital economy promotes the formation of egalitarian gender perspectives, promotes the use of digital technology, and increases labor demand emphasizing the necessity for female-preference occupations. The dividend of the digital economy is tilted toward vulnerable groups in the labor market, including the low-skilled, older, and rural workforce, and only exerts an employment promotion effect on women without parenting burden. Further examination reveals evidence that digitalization has not led to a holistic improvement in the quality of female employment. Digitalization lengthens the working hours of severely underemployed female workers, and improves women's occupational status and job satisfaction; however, it has a minimal impact on protecting employees' rights and interests or reducing overtime workers' work intensity. Nonself-employed, full-time, and part-time workers all benefit from the development of the digital economy, while self-employed workers do not. In addition, a weakening effect of digitalization on the gender employment gap is not evident, which relates to the digital economy generating a female dividend in terms of promoting gender equality and increasing labor demand but resulting in a digital gender divide in the use of digital technology.     

Manufacturing Plants' Use of Temporary Workers: An Analysis Using Census Microdata

Using plant‐level data from the plant capacity utilization survey, we explore how manufacturing plants' use of temporary workers is associated with the nature of their output fluctuations and other plant characteristics. We find that plants tend to use temporary workers when their output is expected to fall; this may indicate that firms use temporary workers to reduce costs associated with dismissing permanent employees. In addition, we find that plants whose future output levels are subject to greater uncertainty tend to use more temporary workers. We also examine the effects of wage and benefit levels for permanent workers, unionization rates, turnover rates, seasonal factors, and plant size and age on the use of temporary workers; based on our results, we discuss various views of why firms use temporary workers.     

Unions and Flexible Employment in Britain and Spain: A Descriptive Note

Spain and Britain are known to have different labor market structures and degrees of employment protection. Despite such differences, they show remarkably similar associations of unionization with temporary employment and nonstandard hours of work. In particular, we find that unionization in both countries is correlated neither with overtime/long hours of work nor temporary employment. In both economies, instead, part-time work is negatively associated with unionization. These cross-national similarities warrant a rethinking of the strategies of enlargement toward flexible forms of work that unions have supposedly adopted in recent years.     

Local IndustryEmployment Share and the Experiences of Displaced Workers

This article examines how industries' share of employment in local labor markets affects displaced workers' reemployment, industry switching, and earnings losses. A key result is that workers displaced from industries with low employment shares are more likely to switch industries after displacement. Earnings loss estimates indicate that for most workers, displacement from an industry that employs a smaller share of the local labor force is associated with larger earnings losses.     

Capacity flexibility allocation in an outsourced supply chain with reservation

We consider a contract manufacturer that serves a limited number of outsourcers (customers) on a single capacitated production line. The outsourcers have different levels of demand uncertainty and the contract manufacturer faces the question how to allocate the contractual capacity flexibility in an optimal way. The contractual capacity flexibility is a contract parameter that sets the amount of demand the contract manufacturer is obliged to accept from the outsourcers. We develop a hierarchical model that consists of two decision levels. At the tactical level, the contract manufacturer allocates the capacity flexibility to the different outsourcers by maximizing the expected profit. Offering more flexibility to the more uncertain outsourcer generates higher expected revenue, but also increases the expected penalty costs. The allocated capacity flexibilities (determined at the tactical level) are input parameters to the lower decision level, where the operational planning decisions are made and actual demands are observed. We perform a numerical study by solving the two-level hierarchical planning problem iteratively. We first solve the higher level problem, which has been formulated as an integer program, and then perform a simulation study, where we solve a mathematical programming model in a rolling horizon setting to measure the operational performance of the system. The simulation results reveal that when the acceptance decision is made (given the allocated capacity flexibility decision), priority is given to the less uncertain outsourcer, whereas when the orders are placed, priority is given to the most uncertain outsourcer. Our insights are helpful for contract manufacturers when having contract negotiations with the outsourcers. Moreover, we show that hierarchical integration and anticipation are required, especially for cases with high penalty cost and tight capacities.     

The Influence of Regular Work Systems on Compensation for Contingent Workers

Using data from a nationally representative survey of U.S. establishments, this article explores how features of regular work influence outcomes for contingent workers. The results show that firms combine regular and contingent work in varied ways: Some managers design contingent work to achieve performance objectives not possible with the regular workforce, whereas managers in other cases create contingent jobs to reinforce the same goals as regular work. In the latter case, contingent workers are more likely to be integrated with regular workers and to receive benefits. Benefit provision for contingent workers is also influenced by traditional internal labor market rules and by spillover effects in which efficiency or regulatory requirements lead benefits to be extended to contingent staff once offered to regular workers.     

Flexible Work and Immigration in Europe

Immigration has risen substantially in many European economies, with far‐reaching if still uncertain implications for labour markets and industrial relations. This article investigates such implications, focusing on employment flexibility, involving both ‘external flexibility’ (fixed‐term or temporary agency and/or involuntary part‐time work) and ‘internal flexibility’ (overtime and/or balancing‐time accounts). The article identifies reasons why immigration should generally increase the incidence of such flexibility, and why external flexibility should rise more than internal flexibility. The article supports these claims using a dataset of establishments in 16 European countries.     

Technological Innovation and Employment in Telecommunications

In this paper we examine how the diffusion of technological innovation in the telecommunications industry influences employment levels across occupations and how a firm chooses among alternative personnel mechanisms to reach its target employment levels. We find that technological change has influenced the demand for different types of workers and has centralized office functions. The adjustment patterns to these demand changes differ by the union status, tenure, age, and gender composition of the affected occupations.     

Supermarkets and agricultural labor demand in Kenya: A gendered perspective

Many developing countries are experiencing a rapid expansion of supermarkets. New supermarket procurement systems could affect farming patterns and wider rural development. While previous studies have analyzed farm productivity and income effects, possible employment effects have received much less attention. Special supermarket requirements may entail intensified farm production and post-harvest handling, thus potentially increasing demand for hired labor. This could also have important gender implications, because female and male workers are often hired for distinct farm operations. Building on data from a recent survey of vegetable farmers in Kenya, a double-hurdle model of hired labor use is developed and estimated. Farmer participation in supermarket channels increases the likelihood of hiring labor by 20%, and demand for hired labor by 61%. A gender disaggregation shows that positive employment effects are especially pronounced for female laborers, who often belong to the most vulnerable population groups. Rural employment generation can be an important vehicle for poverty reduction.     

Redundancies in Chinese State Enterprises: A Research Report

This article examines how the problem of surplus labor isbeing dealt with in some of China's state-owned enterprises. Primarily using interview data from the period 1995-1997, as well as published sources, the article looks at the main methods employed by large state-owned enterprises to reduce the level of surplus labor in their workforce. It also considers how smaller state-owned enterprises are coping in an era where mergers, closures, and bankruptcies are becoming much more common as a means of dealing with loss-making firms, resulting in widespread redundancies in the state-owned enterpriseworkforce. The article illustrates that the potential political repercussions of job losses, as well as direct intervention by local authorities, continue to hinder the freedom of enterprise management to adjust employment levels in the interests of efficiency and productivity. The article also notes the importance of how decisions about downsizing and redundancy are communicated and justified to employees if resistance and social instability are to be minimized. The employment treatment of production workers will be considered separately from that of cadres, since these two groups are subject to different employment regulations and political constraints.     

External Churning and Internal Flexibility: Evidence on the Functional Flexibility and Core-Periphery Hypotheses

Functionally flexible systems for organizing work may reduce job instability and insecurity by reducing employers' reliance on job cuts or contingent work to respond to changes in their environments. Related arguments hypothesize that contingent work allows firms to adjust labor while "buffering" their core of permanent workers from job instability. We find evidence that internally flexible work systems are associated with reduced involuntary and voluntary turnover in manufacturing but that contingent work and involuntary turnover of the permanent workforce are positively related regardless of sector, in contrast to the prediction of the core-periphery hypothesis.     

Flexible Wage Contracts,Temporary Jobs,and Firm Performance: Evidence From Italian Firms

This study focuses on the effects of decentralized wage schemes and temporary forms of employment on firm performance. The effect of monetary incentives on workers' effort and firm performance is a central topic in economics. According to the principal‐agent paradigm, firms (the principal) have to link employees' remuneration schemes to any verifiable indicator of performance to avoid opportunistic behavior. The empirical evidence shows that financial incentives have the potential to exert strong effects on indicators of firm performance, such as productivity and worker absenteeism, although the degree of effectiveness of such schemes varies significantly according to the institutional/economic context in which firms operate. From both a theoretical and empirical point of view, the prediction on the effects of temporary types of employment on effort and productivity is less neat. In light of these considerations, this study uses a sample of Italian firms to provide further empirical evidence on whether and to what extent performance‐related pay schemes and contract flexibility affect workers' effort (in terms of absenteeism) and, in turn, firm productivity. These effects are analyzed for different types of workers (white collar vs. blue collar), working in workplaces characterized by a different degree of uncertainty and risk and in firms operating in different economic and institutional settings. Our results show that wage flexibility has a significant effect on effort and then on firm's productivity and that white‐collar workers are more responsive to monetary incentives than blue‐collar workers. Moreover, the presence of a large share of temporary contracts, implying a lower dismissal probability for permanent workers and a deterioration of the working environment, appears to reduce workers' motivation and effort.     

论中国工业的比较优势

成本比较优势的机制在当代国际分工和国际贸易中仍然发挥作用。中国工业的比较优势主要是劳动力资源丰富。改革开放以来，中国国际贸易的高速增长，主要得益于较好地发挥了劳动力便宜的比较优势。由于二元经济结构和地区经济发展水平上的差异将继续存在，同时由于劳动力供给大大超出劳动力的需求，中国劳动力便宜的比较优势将能够长期保持下去。但是，劳动力便宜的比较优势是相对的，在资本和技术密集型产业，这种优势并不明显。企业办社会和人浮于事等大大抵消了劳动力便宜的优势。所以，在市场竞争中，必须高度重视提高劳动生产率。制造业员工的工资水平低，虽然有利于降低企业生产成本，但也有消极作用：一是在国际贸易中，导致国民福利的流出；二是限制了低收入阶层的购买力，抑制了国内需求。逐步提高制造业工人的工资水平是必要的。     

Liberalization Only at the Margins? Analysing the Growth of Temporary Work in German Core Manufacturing Sectors

Drawing on workers’ surveys and workplace interviews, this article investigates the growth of temporary work in German manufacturing sectors since the 1980s. Findings partly confirm a ‘dualization’ scenario as workers without industry‐specific vocational training are more likely to be on a temporary contract than skilled workers, and the gap has widened over time. However, also skilled workers have become increasingly vulnerable to casualization due to job routine and the erosion of industrial relations. Evidence confirms the crucial role of institutions in supporting the linkage between specific skills and employment stability, and suggests that the liberalization of the employment relationship has the potential to advance also in the core of the German economy.
