The impact of uncertainty on firm investment: evidence from machinery industry in Liaoning province of China

We test the impact of uncertainty on investment of Chinese firms during market transition with a sample of 195 firms in the machinery industry in Liaoning province of China during 1993–1998. The system Generalized Method of Moments (GMM) estimates show that both demand and labor costs uncertainties do not affect investment of state enterprises, while labor costs uncertainty has a positive effect on investment of collective firms. This result suggests that managers of state enterprises have little incentive to respond to uncertainty probably due to the ex ante arrangements of the contract responsibility system, while collective firms show risk-taking behavior during market transition. We also find that sales growth is an insignificant signal for investment of both state and collective enterprises, violating the standard accelerator principle. We provide a few possible explanations to this result.     

Wage premia and skill upgrading in Italy: why didn't the hound bark?

This paper presents firm-level evidence on the change of the employment share and the wage premium of non-manual workers in Italian manufacturing during the nineties. We find that the relative stability of the aggregate wage premium and employment share hides offsetting disaggregate forces: technical progress raises the relative demand for skilled labor within firms, whereas demand changes associated with trade reduce the relative demand for skills. Moreover, it is within the class of non-manual workers that most of the action takes place: the wage premium and employment share of executives rise substantially, while those of clerks fall in a similar proportion. Finally, we find that the export status of firms plays a key role in explaining labor market dynamics: exporters account for most of both demand-related and technology-related shifts. Overall, our results for Italy question the conventional view that the labor market is “rigid” due to labor market institutions.     

The evolving pattern of the wage–labor productivity nexus in China: Evidence from manufacturing firm-level data

By employing a large dataset of nation-wide state-owned and non-state-owned manufacturing enterprises in the period 1998–2007, this paper analyzes the evolving pattern of the correlation and spread between wages and labor productivity in China's manufacturing sector and its influence factors. We find that although a significant positive correlation between wages and labor productivity in manufacturing firms exists, this positive nexus has become weak and loose. We also find that, since the 1990s, the labor productivity of Chinese manufacturing enterprises has gained a much greater growth rate than that of the wage level, and therefore the spread between wages and labor productivity has been widening over time. A variety of factors that have influenced the wage–labor productivity nexus of Chinese manufacturing enterprises are identified and discussed with regression models.     

How do workers decide their jobs? The influence of income,wage and job characteristics

This paper provides results on the economic decision‐making process of Spanish workers, who decide their jobs from the effects of variations in the non‐wage income, the wage and the prices of non‐pecuniary job characteristics. To that end, we formulate a non‐separable generalization of the Linear Expenditure System (NLES) as a joint model of labor supply and job characteristics demand, estimated separately for both males and females, using a 1991 Spanish survey. The main results show that: (i) some job characteristics have a positive effect on the wage, whereas others have a negative effect; (ii) the average percentage effect of employer size and the complexity index are higher for males than for females, with the fatal accident risk displaying similar values; (iii) if the non‐wage income of every worker increases, these individuals will prefer to devote less hours to work, and will also prefer jobs in smaller companies and with a lower risk; and (iv) if the wage and hedonic prices of non‐pecuniary job characteristics increase, then both males and females will prefer to reduce their labor supply, and devote their available time to jobs in bigger firms, with a higher risk and complexity.

Firm-specific wage growth and changes in the labor market for managers

This paper analyzes recent changes in the employment relationships between managers and firms. In both Becker's and Lazear's models of firm-specific wage growth, compensation is deferred from early in an employee's tenure with a firm until later in the contract. The deferred compensation bonds the worker to the firm. Based on cross-sectional data from Current Population Surveys, rates of firm-specific wage growth are estimated for the managerial labor market. The findings show that the rate of wage growth that is firm-specific for managers in manufacturing industries declined significantly during the early 1980s. It is estimated, for example, that a manager with 12 years of tenure in a manufacturing firm enjoyed, on average, a 25% wage premium in 1979 over an otherwise similar manager who was a new hire in a firm. By 1983 the firm-specific wage premium for a manager with 12 years of tenure was only 5%. These changes represent a significant reduction in the strength of the employment bond between firms and managers, and a reduction in the incentive effects previously enjoyed by firms from the use of deferred-compensation schemes. This change is consistent with the significant increases in the displacement rates of managers that occurred during the 1980s.     

Accounting for wage and employment changes in the US from 1968–2000: A dynamic model of labor market equilibrium

In this article, we present a unified treatment of and explanation for the evolution of wages and employment in the US over the last 30 years. Specifically, we account for the pattern of changes in wage inequality, for the increased relative wage and employment of women, for the emergence of the college wage premium and for the shift in employment from the goods to the service-producing sector. The underlying theory we adopt is neoclassical, a two-sector competitive labor market economy in which the supply of and demand for labor of heterogeneous skill determines spot market skill rental prices. The empirical approach is structural. The model embeds many of the features that have been posited in the literature to have contributed to the changing US wage and employment structure including skill-biased technical change, capital-skill complementarity, changes in relative product-market prices, changes in the productivity of labor in home production and demographics such as changing cohort size and fertility.     

Facilitating offshoring with enterprise technologies: Reducing operational friction in the governance and production of services

The development of cheap and robust communications technologies has lowered the cost of conducting business transactions across international boarders and opened up low wage rate global labor markets to firms facing demand for cheap and efficient service delivery. A review of transaction cost theory and operations management models of service process disaggregation reveals parallels between the how firm boundaries are determined and how certain service process elements can be disaggregated from face-to-face customer contact. This theoretical background is used to identify challenges to the effective offshoring of service processes. The competitive capability literature offers suggestions as to how firms might acquire the internal capabilities required to manage offshore service processes. Propositions are developed on how the standardized transactional infrastructure of enterprise technologies (and the organizational competencies developed by successful enterprise system adopters) may help mitigate the challenges of offshore governance.     

The relevance of wage differentials in neoclassical urban growth

This paper examines the effect of introducing spatial wage rate differentials in a neoclassical model of urban growth. To this purpose, a formal theory of the labor market is derived which differs from the Borts-Stein-Muth one in the explicit inclusion of a wage variable. The introduction of this variable improves noticeably the empirical performance of the model.     

Temporary international migration and the nontraded sector of the labor-importing developing economy

In this paper the author examines the effects of external migration on the nontraded sector of the labor-importing developing economy. It is found that devaluation by the labor-exporting country will reduce the pressure on excess demand for labor and reduce the price of nontraded goods. Increases in the migrant workers’ consumption expenditures, the government expenditures on nontraded goods and the price of traded goods will increase the pressure on excess demand for labor and raise the price of nontraded goods. The effects of an increase in host country nominal wage, however, will remain ambiguous.     

A firm level perspective on migration: the role of extra-EU workers in Italian manufacturing

A production-theory approach to migration is adopted in this paper to address the role of migrant workers from extra-EU countries in Italian manufacturing firms. The adoption of flexible functional forms to model firm-level technology lets us directly derive different measures of elasticity from the coefficients of the estimated production and cost functions. The use of foreign labour is shown to affect the industry composition in favour of low skill intensive sectors and the estimated cross demand elasticities confirm the complementarity between migrant and native workers found in previous studies. However, the two labour inputs prove to be substitutes in terms of the Morishima elasticity of substitution: in general, firms tend to increase the foreign labour intensity of production in response to a decline in migrants’ wage, while the migrant to domestic labour ratio responds to changes in the domestic workers’ wage only for firms in low skill intensive sectors.     

Volatile multinationals? Evidence from the labor demand of German firms

Does more FDI make the world a riskier place for workers? We analyze whether an increase in multinational firms' activities is associated with an increase in firm-level employment volatility. We use a firm-level dataset for Germany which allows us to distinguish between purely domestic firms, exporters, domestic multinationals and foreign multinationals. Employment in multinationals could be more volatile than employment in domestic firms if multinationals were facing more volatile demand or if they react more to aggregate developments. We therefore decompose the labor demand of firms into their reaction and their exposure to aggregate developments. We find no above-average wage and output elasticities for multinational firms.     

Testing the intertemporal labor supply model: are jobs important?

The neoclassical life-cycle labor supply model assumes that hours of work are determined by labor supply choices alone and does not include a role for employers or job distinctions. An alternative model in which employers have an interest in employee hours and changing jobs is costly may reconcile weak and conflicting evidence regarding the neoclassical model. An important implication of such an alternative is that individuals may face hours constraints on a job and thus can choose hours freely only between jobs. This paper tests several implications of the neoclassical model against this alternative model of hours determination. Using a unique panel of individuals and jobs constructed using data on women from the 1988–1992 Panel Study of Income Dynamics, I compare hours variances and labor supply elasticities measured within and between jobs. Results provide some evidence against the neoclassical model and suggest that ignoring the role of employers in determining hours of work can lead to downward bias in estimates of labor supply elasticities.     

Measuring labor cost for productivity comparison

This paper presents measures of labor cost applicable when the wage and marginal product are not equal by period. The user cost of labor, an alternative to the wage, is the price of hiring the services of the worker per unit time. This user cost is dependent on the sequence of wages earned by a worker over a career, interest rates, and career length or eventual tenure. For the United States, 1963–1978, labor compensation shares based on the wage exceed those for the user cost. After 1978, the reverse obtains. The contribution of labor, and measured productivity performance is sensitive to the price of labor services.This paper was processed by M. Brown.     

The returns to formality and informality in urban Africa

This paper addresses the questions as to the size and causes of earnings differentials in two urban African labor markets, those of Ghana and Tanzania. We have panel data so we can ask how far time invariant unobservables, market ability for short, matters in the determination of earnings. We also have information on whether the individual is own self-employed, self-employed with employees, a private or public sector wage employee and the size of the enterprise in which wage employees work or which the self-employed owns. We find, mirroring work on developed economies, that unobserved individual market ability is by far the most important factor explaining the variance of earnings. With controls for such ability the gap between private wage employment and civil servants is about 50%. With controls for enterprise size we find that wage employees earn the same as the self-employed in both Ghana and Tanzania. Enterprise size matters. At most half of the OLS effect of size on earnings can be explained by unobservable ability. Workers in the largest firms are the high earners with wage rates which exceed those of civil servants. These results all assume exogenous movement. We find evidence that endogeneity bias may be serious and may be understating the extent of both the size effect and the private sector wage (negative) premium. The implications of our results for understanding the nature of formal and informal employment in Africa are discussed.     

The importance of firms in wage determination

Firms are central to many theories of the labor market. However, the actual degree to which firms shape the structure of wages is still not well understood. This paper investigates (i) the importance of firms in explaining wage differences across individuals and industries, and (ii) how the nature of interfirm mobility – job-to-job vs. job-unemployment-job – affects the relative importance of firms and workers in wage determination. Results indicate that (i) firms are much more important in explaining the variance of average wages across industries rather than across individuals, and (ii) using job-to-job transitions to identify the firm's contribution to the wage rate reduces the importance of firm wage policies in explaining wage differences by as much as 50%.     

外资企业技术授权与劳动力技能结构升级——来自世界银行中国企业调查数据的经验证据

在中国高技能劳动力供给不断增加的背景下,引进国外先进生产技术能够促进本土企业实现技术进步,进而扩大企业对高技能劳动力的相对需求。作为技术引进的途径之一,本土企业使用外资企业授权的生产技术与企业内高技能劳动力就业的关系却较少受到关注。本文利用世界银行2012年中国企业调查数据对这一问题进行初步探索。研究结果表明,获得外资企业技术授权能够显著提升劳动力技能结构,影响途径包括生产规模扩张、研发投入增加和资本深化。其中,生产规模和研发投入为正向途径,资本深化为反向途径。此外,外资企业技术授权作为本土企业扩大对高技能劳动力的相对需求的途径之一,对避免技能层面的要素错配和结构性失业具有重要意义。     

Markup Pricing and the Auto Industry: A Partial Explanation of Stagflation in an Oligopolistic Economy

A bstract . Price leadership firms and especially wage leadership unions frequently are not operating at points of maximization in the neoclassical sense, because contrived high level demand has brought low price consciousness or elasticity of demand for their commodities or services. Accordingly, they can get higher profits or wages anytime they choose to raise their price except during severe recession. If output falls as a consequence, goveniment and the central hank have stood ready to expand total spending. The contrived high demand has interacted with oligopolistic practices to obviate the distinction between elasticity for the firm and that of its industry, with empirical studies showing demand elasticity commonly not much above unity. The automobile industry is the focus of attention in this study. It appears that stable and high employment market capitalism no longer is possible, because at a minimum t requires generalized maximization behavior, which involves operation against constraining supply and demand parameters.     

Privatisation or Competition?

Market competition is essential for any economy to be efficient. In order to develop competition in a transition economy, it is conventionally thought that privatisation should take place first. This wisdom has been challenged by the Chinese reform experience of the last two decades, which modified the incentive structure of state enterprises and created markets and market competition in the absence of large scale privatisation. China's experience, however, raises the question of whether its chosen type of reform is sufficient to promote competition in a market dominated by public firms. To answer this, we need to know what kind of markets were created – regional markets closed to trade or unified markets with easy access – and whether or not improved incentives for state firms have led to competition. This paper investigates these questions on the basis of a survey of both theory and empirical evidence; and finds that the Chinese reform policies did succeed in stimulating competition among state firms.     

Age-specific dynamic labor demand and human capital investment

To study the optimal age-specific labor demand and human capital investment at the firm level we extend the standard dynamic labor demand model by introducing ‘age’ as a second dynamic variable and distinguish between two types of workers: ‘low skilled’ and ‘high skilled’. Applying an age-structured optimal control model we derive qualitative features of the optimal age-specific hiring and training effort. For the case of a linear revenue and production function we prove that firms do not anticipate changes in adjustment costs in their optimal decisions. This result no longer holds if a nonlinear revenue or production function is considered.
