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.     

Imported inputs and skill upgrading

This paper studies the effect of imported inputs on the relative demand for high-skill labor. To this purpose, it applies propensity score matching techniques to firm-level data for 27 transition countries. The results show that importing inputs induces skill upgrading. Specifically, it explains more than one-quarter of the unconditional difference between importers and non-importers in the employment share of high-skill workers. The paper explores possible mechanisms behind this result. In particular, it reports suggestive evidence that importing leads firms to engage in high-skill intensive activities, such as production of new goods, improvement of product quality and, to a lesser extent, R&D and technology adoption.     

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.     

TRADE LIBERALIZATION,LABOR DEMAND SHIFTS AND EARNINGS INEQUALITY IN SINGAPORE

This article investigates the relative wage between skilled and low skilled labor in a small open economy with traditionally few labor market rigidities. It looks at the role of relative skills demand and supply in determining skills premium and explores the extent to which trade liberalization affects the skills wage gap. Indications are that greater openness is linked to higher labor demand elasticity and/or technological progress. The evidence also suggests that rapid acceleration in labor demand for skills and trade liberalization has widened the wage gap between skilled and low skilled labor. This result persists regardless of industry type.     

Impact of trade liberalization on firm's labour demand by skill: The case of Tunisian manufacturing

This paper investigates the impact of the trade liberalization process in Tunisia on employment by distinguishing different skills and different types of firms using micro level data covering the period of 1983–1994. There is considerable disagreement among analysts on the impact of recent trade reforms upon labour. Our contribution to these debates in this paper is essentially an empirical issue. The analysis of a Tunisian firm's data may be viewed as an attempt to apprehend how employment in Tunisia, a developing country, adjusted to the trade reforms. Using micro-level detail on individual firms, we are able to trace the relationship between changes in trade policies and manufacturing employment at firm level and by skill. Although trade reforms are generally implemented at the sector level, their effects may vary significantly across firm characteristics such as output orientation. We measure the effects of trade policy on employment according to different types of firms. We also associate changes in employment directly with a measure of change in trade protection, rather than linking them to changes in imports and exports which would be more common. The results suggest that the impact of trade liberalization on labour demand depends on a firm's characteristics. In particular, the estimates obtained suggest that trade liberalization has beneficial effects on employment for exporting-firms. Conversely, trade liberalization has negative and disciplinary effects on employment for domestically oriented firms. The reduction in tariff levels conducted in this first phase of liberalization in Tunisia seems to have had effects with different intensity on unskilled labour and on skilled labour; this justifies the examination of these two skills.     

Service Offshoring and the Skill Composition of Labour Demand*

This article studies the effects of service offshoring on the skill composition of labour demand, using novel comparable data for nine Western European countries between 1990 and 2004. The results show that service offshoring raises the relative demand for high‐ and medium‐skilled workers. Its effects are qualitatively identical, and quantitatively similar, to those of material offshoring. Additional evidence suggests, however, that the two types of offshoring may work through different channels: complementarity between imported services and domestic skills in the case of service offshoring, substitution of low‐skilled labour in the case of material offshoring. Overall, the effects are not large in economic terms.     

Immigration and firm productivity: evidence from the Canadian Employer-Employee Dynamics Database

Previous studies on the impact of immigration on productivity in developed countries remain inconclusive, and most analyses are abstracted from firms where production actually takes place. This study examines the empirical relationship between immigration and firm-level productivity in Canada. It uses the Canadian Employer-Employee Dynamics Database that tracks firms over time and matches firms with their employees. The study finds that there is a positive association between changes in the share of immigrants in a firm and changes in firm productivity. This positive effect of immigration on firm productivity is small, but it is stronger over a longer period. The effect tends to be larger for low-skilled immigrants as compared with highly-skilled workers, as firm productivity growth is more strongly associated with changes in the share of recent immigrants (relative to established immigrants), and immigrants who intended to work in non-high skilled occupations (relative to immigrants who intended to work in high-skilled occupations). Those differences are more pronounced in technology-intensive and knowledge-based industries. Immigration is found to have little estimated effects on capital intensity in a firm. Finally, this study finds that high skill and lower skill immigrants have similar effects on average worker earnings arising from the positive productivity effect of immigration, but only skilled immigrants are associated with higher firm profits.

     

Misallocation,informality, and human capital: Understanding the role of institutions

The aim of this paper is to quantify the role of formal-sector institutions in shaping the demand for human capital and the level of informality. We propose a firm dynamics model where firms face capital market imperfections and costs of operating in the formal sector. Formal firms have a larger set of production opportunities and the ability to employ skilled workers, but informal firms can avoid the costs of formalization. These firm-level distortions give rise to endogenous formal and informal sectors and, more importantly, affect the demand for skilled workers. The model predicts that countries with a low degree of debt enforcement and high costs of formalization are characterized by relatively lower stocks of skilled workers, larger informal sectors, low allocative efficiency, and measured TFP. Moreover, we find that the interaction between entry costs and financial frictions (as opposed to the sum of their individual effects) is the main driver of these differences. This complementarity effect derives from the introduction of skilled workers, which prevents firms from substituting labor for capital and in turn moves them closer to the financial constraint.

Overlapping labour markets

Overlapping labour markets arise when some types of workers do not meet employers with some types of jobs. For example, skilled workers could seek high-skill or low-skill jobs, but low skill workers could be limited to low-skill jobs. The paper derives conditions for equilibrium and efficiency, distinguishes reducible from irreducible overlapping labour markets, and describes distributional impacts of proportional demand shifts and technological change. Many labour models incorporate the structure of overlapping labour markets, so that the results have widespread applicability.     

Offshoring in the New Global Political Economy

abstract    This essay challenges claims by economists and management scholars that 'offshoring' is simply another form of trade with mutual benefits. I argue that reducing wages through offshoring leads to wealth creation for shareholders but not necessarily for countries and employees, and that many displaced workers have difficulty 'trading up' to higher skilled jobs. Offshoring is a new phenomenon that entails the organizational and technological ability to relocate specific tasks and coordinate a geographically dispersed network of activities. It decouples the linkages between economic value creation and geographic location. The result is the creation of global commodity markets for particular skills and a shift in the balance of market power among firms, workers, and countries.     

Firms' investments in general training and the skilled labour market

An adverse selection model is analysed, where firms can train or hire a skilled worker. In equilibrium, the market wage is determined by supply and demand. The quality of the supplied skilled labour is negatively biased, because workers stem from firms that shut down and from firms that observed their trainee's bad quality during the training. If fewer firms were to shut down, then the supplied average quality deteriorates and the incentive to train increases. The incentive is inefficient, because firms must share the informational rent and they free-ride. Ex ante workers may wish to increase the firms' bargaining power.

An exploratory review of the relationship between enterprise training and technology upgrading: evidence from South African manufacturing firms

The study examines the extent to which disaggregated training variables are related to technological upgrading, in the context of a middle-income developing country trying to manage its integration into the global economy. For a developing country, successful integration into the global economy requires that local manufacturing firms are able to competitively restructure, as a precondition for survival and long-term growth. Consequently, skills and technological upgrading are crucial in raising the international competitive advantage of local firms. Enterprise-provided training is one means that can be used by local firms to continuously upgrade their knowledge bases, increase their international competitiveness, and enhance employment growth over time. This paper uses South Africa as a case study, to demonstrate how economic reform measures can expose skills deficiencies in the manufacturing sector and lead to an increase in capital intensity of the sector. Exposure of skills deficiencies, in turn, raises the importance of skill-upgrading through schooling and training of existing workforce. Despite a couple of studies on the evolution of the labour market in South Africa, no previous research has explicitly examined the relationship between technological upgrading and disaggregated training/learning variables at the firm level. This paper aims to fill that gap by focusing on disaggregated enterprise-based training efforts. The study uses the Human Capital theoretical framework to answer the main research question: Which disaggregated learning variables (i.e., on-the-job or off-the-job training offered to different occupational groups) are significantly associated with technological upgrading? The study raises possible issues of heterogeneity in returns to training offered to different occupational groups in the context of technological-upgrading. On the other hand, technological upgrading may not necessarily always disadvantage all unskilled workers. Possible policy implications of research findings are outlined.     

Outsourcing and computers: Impact on urban skill level and rent

Cities in the U.S. with a higher initial share of college graduates have had a greater subsequent increase in this share over the past two decades. Concurrently, housing prices have grown faster in these skilled cities. This paper argues that the diffusion of computers and outsourcing may partly explain these two phenomena. In the presented model, skilled workers are more productive in skilled cities and need unskilled support services. The cities' unskilled workers can perform the support services, but when it is cheaper, such services can be undertaken by computers or outsourced to less-skilled cities. New technologies facilitating computerization and outsourcing can increase the skill share and housing prices in skilled cities relative to less-skilled cities, under reasonable assumptions. The basic economics is that the new technologies diminish the demand for unskilled workers in skilled cities and permit skilled workers to earn higher wages, which in turn increases the supply of skilled workers in skilled cities and drives up housing prices. Empirically, this paper documents five stylized facts that the theory can rationalize. Particularly important is rising skill premium in skilled cities relative to less-skilled cities, which supports a production theory involving shifts in labor demand.     

Acquisition of skills, labor subsidies, and agglomeration of firms

The paper develops an analytically solvable model of new economic geography in which agglomeration of firms is caused by workers' investment in the acquisition of skills. Skilled workers earn high wages and have a large demand for goods. Since firms are attracted towards the demand, they locate at proximity of skilled workers. More workers invest in the acquisition of skills when more firms ask for these skills. Consequently, partial or full agglomeration of firms may be the location equilibrium. We also show that a reduction in transport costs increases the regional governments' incentives to subsidize the acquisition of skills.     

Returns to Skills and the Distribution of Wages: Spain 1995–2010

In contrast to the pattern observed in other developed countries, the Spanish wage distribution compressed between 1995 and 2006 and became more disperse afterwards, so that in 2010 wage inequality was roughly similar to 1995. In this paper, we analyze the role of supply and demand factors when accounting for these facts. We start by decomposing observed wage changes into changes in the composition of the labour force and changes in the returns of workers' and jobs' characteristics. The results indicate that the compression of the wage distribution between 1995 and 2006 is largely explained by changes in returns, and particularly, by a decrease in the returns to education. We show that both the increase in the supply of high‐skilled workers and the increasing weight of low‐skilled occupations are related to the decreasing trend in the skill premium over this period. In contrast, the widening of the wage distribution after 2006 is largely explained by an increase in the relative demand for high‐skilled workers generating an increase in the school premium.     

The China effect: Evidence from data at firm level in Thailand

This study investigates how competition with Chinese imports affects firms in Thailand. Using World Bank data on Thailand and United Nations trade data from 2003 to 2006, the empirical results show that there is no significant impact of Chinese import competition on employment, wages, or labor income share. However, further checks show that for firms with lower productivity, the impact on employment and labor income share is more likely to be negative. The impact of Chinese import competition on profit margins is significantly positive. Considering the impact on labor income share and profit margins, we conclude that because of Chinese import competition, income distribution possibly goes in disfavor of labor. Our study shows that the impact of Chinese import competition on the skilled labor ratio is positive and significant. This result suggests that Thai firms are on the path to skill upgrading as a result of Chinese import competition, which is helpful for Thailand’s long-run economic growth. As firms with low productivity are more likely to be negatively affected by Chinese import competition, improving productivity is still an efficient way to counter such competition.     

The effect of trade on productivity growth and the demand for skilled workers in Canada

We use an input–output model to examine the effect of trade integration on productivity growth and the demand for skilled workers in Canada for the period 1981–1997. We find that trade integration has a positive effect on both labour productivity and total factor productivity. Labour productivity and total factor productivity grew faster in export and import industries than in the total business sector over this period, and this productivity growth gap has widened over time. Canada is found to have a comparative advantage in capital- and natural-resource-intensive industries, although it has declined over time. We find that trade integration has little effect on the demand for skilled and unskilled workers in Canada.     

The determination of wages of newly hired employees: Survey evidence on internal versus external factors

This paper reports findings on the relative importance of internal versus external factors in the setting of wages of newly hired workers. The evidence, from a rich firm-level survey on wage and price-setting procedures in 15 European Union countries, suggests that external labour market conditions are less important than internal pay structures in determining hiring pay, with internal pay structures binding even more often when there is labour market slack. When explaining their choice firms allude to fairness considerations and the need to prevent a potential negative impact on effort. Cross-country differences are found to depend on institutional factors: countries in which collective agreements are more prevalent and collective agreement coverage is higher report more often internal pay structures as the main determinant of hiring pay. Within-country differences are found to depend on firm and workforce characteristics: there is a strong association between the use of external factors in hiring pay, on the one hand, and skills (positive) and tenure (negative) on the other.
