Trade,technology and skills: Evidence from Turkish microdata

In this paper we report evidence on the relationship between trade openness, technology adoption and the relative demand for skilled labour in the Turkish manufacturing sector, using firm-level data over the period 1980–2001. In a dynamic panel data setting, using a unique database comprising data from 17,462 firms, we estimate an augmented cost share equation whereby the wage bill share of skilled workers in a given firm is related to international exposure and technology adoption.It emerges that R&D expenditures are positive and significantly related to skill upgrading. This result supports the skill-biased technological change argument in the case of a middle-income country such as Turkey.Moreover, the firm-level analysis reveals a positive impact of technological transfer from abroad, foreign ownership and exporting status on the demand for skills, highlighting the role of increasing international openness in fostering skill upgrading within firms.Our microdata also allow us to investigate the direct impact of import flows in shaping the relative demand for skills. The results show that those firms belonging to the sectors experiencing rapid increase in the share of inputs imported from industrialised countries also experience a higher increase in the labour cost share of skilled workers. This finding provides further support for the hypothesis that imports from industrialised countries imply a transfer of new technologies, in turn leading to a higher demand for skilled labour (the so-called skill-enhancing trade hypothesis).     

Endogenous qualifications and firms'' agglomeration

This paper analyzes firms' location when workers endogenously choose to qualify for professional skills but when they remain uncertain about the potential match between their personal abilities and/or affinities and the firms' specific production tasks. By qualifying in a region where firms agglomerate, workers benefit from higher prospects of good match. At the equilibrium, we show that firms may locate in a single cluster, symmetric clusters or even asymmetric clusters. Comparative statics with respect to product market demand and labor supply parameters are provided.     

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.     

Job hopping, earnings dynamics, and industrial agglomeration in the software publishing industry

This paper investigates the implications of industrial clustering for labor mobility and earnings dynamics in one large and increasingly important high-technology sector. Taking advantage of longitudinal employee-employer matched data, I exploit establishment-level variation in agglomeration to explore how clustering in the software publishing industry affects labor market outcomes. The results show that clustering makes it easier for workers to job hop within the sector. Higher earnings levels in more agglomerated areas are partly attributable to sorting across locations among workers and firms in the industry on the basis of observable and unobservable characteristics. Controlling for this heterogeneity, workers in clusters have relatively steep earnings-tenure profiles, accepting lower wages early in their careers in exchange for stronger earnings growth and higher wages later. These findings are consistent with theoretical models in which agglomeration improves labor market coordination and facilitates greater learning and human capital formation.

Marshallian labour market pooling: Evidence from Italy

This paper employs a unique Italian data source to take a comprehensive approach to labour market pooling. It jointly considers many different aspects of the agglomeration — labour market relationship, including turnover, learning, matching, and hold up. It also considers labour market pooling from the perspective of both workers and firms and across a range of industries. Overall, the paper finds some support for theories of labour market pooling, but the support is weak. Specifically, there is a general positive relationship of turnover to local population density, which is consistent with theories of agglomeration and uncertainty. There is also evidence of on-the-job learning that is consistent with theories of labour pooling, labour poaching, and hold up. In addition, the paper provides evidence consistent with agglomeration improving job matches. However, the labour market pooling gains that we measure are small in magnitude and seem unlikely to account for a substantial share of the agglomeration benefits accruing to Italian workers and firms.     

Production subcontracting and location

Using data from a panel of Spanish manufacturing firms, I examine factors that explain firms' production subcontracting decisions and test whether there is any evidence that production subcontracting is facilitated in areas typically associated with higher agglomeration economies. The results show that location matters. Firms in industry agglomerations are more likely to subcontract production activities. While in general, larger and older firms as well as high wage firms show a greater probability for production subcontracting, industry agglomeration particularly facilitates subcontracting for smaller and lower wage firms and it allows firms to respond to a greater degree to expansive demand conditions by taking advantage of subcontracting.     

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.

Demand- and Supply-Side Agglomerations: Distinguishing between Fundamentally Different Manifestations of Geographic Concentration

Agglomeration research investigates the benefits that firms receive from locating in close geographic proximity. Despite a substantial surge in interest in this topic over the past 20 years, a lack of distinction among unique manifestations of spatial concentrations of similar firms threatens continuing progress in this stream of research. We argue that agglomerations of related firms that draw benefits from the supply-related externalities of increased access to specialized labour, specialized inputs, and knowledge spillovers are fundamentally different from those that draw benefits from heightened demand realized through reduction in consumer search costs. Extending agglomeration theory, we explicate the differences between these distinct phenomena, discuss how the nature of key theoretical relationships varies across these agglomeration types, and demonstrate significant implications for research. We discuss how the differences affect a host of theoretical relationships and empirical research decisions.     

External spillovers, internal spillovers and the geography of production and innovation

We consider a three-location duopoly model such that (i) firms choose production and innovation locations before (Bertrand) competition takes place and (ii) there are internal and external knowledge spillovers. We show: (1) agglomerations where firms earn negative profits may exist when there are both external and internal knowledge spillovers; (2) greater external spillovers do not necessarily favor agglomeration; (3) decreasing communication costs tend to favor agglomeration; (4) there are exactly two types of agglomeration equilibria: either both firms innovate in the agglomeration, or there is an innovator and an imitator; and (5) if there is a location where both firms produce, then innovation must take place in this location.     

Uncertainty,hiring and firing costs,and the determinants of profit‐sharing rules

We consider a firm run by a manager who acts on behalf of shareholders. The firm produces a commodity whose demand evolves stochastically over time. The firm's employees possess firm‐specific skills and knowledge and thus can bargain over profits with shareholders immediately before the firm hires or fires workers. The firm will distribute more portions of profits to employees when it incurs higher costs to hire or fire workers. In addition, as uncertainty in demand increases, the firm will distribute smaller (larger) portions of profits to employees if the firm does not have the option to fire (hire) workers.     

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.     

Home market effects with endogenous costs of production

In a standard imperfect competition model, we endogenize the costs of production of firms in the increasing returns sector (IRS) via process R&D. We show that firms in the larger region in terms of demand invest more in R&D (i.e.: they are bigger in size and have lower marginal costs) than firms in the smaller region, since the former exploit larger economies of scale in production to pay for the costs of R&D. As a result, when the return on R&D is high, the larger region does not employ disproportionately more labor nor attracts a disproportionately larger share of firms in the IRS in relation to share of demand it hosts, i.e.: negative home market effects (HMEs) in employment and in the number of firms. When this occurs, only partial agglomeration of the IRS in the larger region is sustainable in equilibrium. Even so, the larger region always runs trade surplus in the IRS, i.e.: HME in trade patterns.     

Strategic segmentation in front-line services: matching customers,employees and human resource systems

This paper examines variation in the use of high involvement work practices in service and sales operations. I argue that the relationship between the customer and front-line service provider is a central feature that distinguishes production-level service activities from manufacturing. In particular, through strategic segmentation, firms are able to segment customers by their demand characteristics and to match the complexity and potential revenue stream of the customer to the skills of employees and the human resource system that shapes the customer–employee interface. Unlike manufacturing, where high involvement systems have emerged in a wide variety of product markets, therefore, service organizations are likely to use high involvement systems only to serve higher value-added customers because of the high costs of these systems and the labour-intensive nature of services. Data from a nationally random sample of 354 call centres in US telecommunications documents this pattern: from classic mass production approaches for back office workers and increasingly for front office residential service agents, to greater involvement for small business service providers and high involvement practices for middle-market service agents.     

Foreign remedies for local difficulties: the case of three Scottish manufacturing firms

Literature on Japanese transplant manufacturing firms in the automotive sector often emphasise the importance placed on attitude as opposed to skills in the hiring decisions for line workers. In this paper, a case study of one second-tier components supplier for a major Japanese automotive assembler in the Midwestern United States provides the opinions of senior managers and human resource associates regarding recruitment and selection practices. In-depth interviews, carried out over a two-week period in August 2000, are used to develop an understanding of the recruitment and selection process for line workers as well as to investigate the desired skills and value of previous Japanese experience. Results of the case study analysis are compared with two models from the literature: (1) a model of recruitment and selection at Japanese automotive-related firms in Japan and (2) a model of recruitment and selection at Japanese transplant automotive-related firms abroad. Deviations from the two models point not to a new paradigm of ‘second-generation’ Japanese transplants – those that have moved into regions quite familiar with Japanese firms and related management and production methods – but rather to overall weaknesses in the stereotypical models. Managerial opinions within the case study firm place limited value on familiarity with a Japanese environment, considering such experience secondary to attitudes and work ethics that are in line with the philosophy of the case study firm.     

Changes in cognitive function: Practical and theoretical considerations for training the aging workforce

Forecasts of the labor force supply over the next 20 years reveals a demographic bubble of older retirees that is not offset by the percentage of qualified incoming younger workers (Bureau of Labor Statistics U.S. Department of Labor, 2014). Understanding how training may be used to retain older employees can lead to a competitive edge for firms, given the upcoming need for skilled workers. Training also carries benefits for late career workers or job seekers as a means to increase their existing skills or as a gateway to more lucrative jobs. We review shifts in major cognitive skills and information-processing skills over time and make suggestions for enhancing the training environment for older learners based on that information. We also suggest research needs targeting late-career trainees. These practical recommendations for trainers and program designers, and suggestions for future research may lead to more age-inclusive and comprehensive theories of training-based learning.     

Urban Wages and Labor Market Agglomeration

Using the 5% public use micro sample of the 1990 U.S. census, we find that observationally equivalent workers in the manufacturing sector earn higher wages when they are in urban labor markets that have a larger share of national or metropolitan employment in their same occupation and industry groups. Quantitatively, the effect is large, with an elasticity (measured at the means) of between 1.2 and 3.6 for these effects. We interpret the willingness of firms to pay more for equivalent workers in dense markets as evidence of an agglomeration economy in urban labor.     

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.     

Geographical and cognitive proximity effects on innovation performance in SMEs: a way through knowledge acquisition

This study explores the relative influence of geographical and cognitive proximity to explain innovation performance. This paper deepens the controversy between the significance of both types of proximity, contributing to a better understand their interconnections. The study further analyzes to what extent knowledge acquisition provides a congruent explanation of the effectiveness of innovation in proximity contexts. The paper has tested a structural model based on a sample of 224 Spanish footwear firms. Footwear industry is a mature and traditional industry with a significant presence of the territorial agglomeration of firms all over Spain. Findings suggest both a direct and indirect effect of cognitive proximity on innovation performance. However, an excess of geographical proximity produces spatial lock-in, thus limiting the access to new knowledge and lowering innovations. By contrast, proximity in terms of goals and culture leads firms belonging to a territorial cluster to achieve knowledge acquisition resulting in relevant innovation. Findings suggest that although transferable valuable knowledge exists in clustered contexts firms should adopt a proactive behavior to have access common knowledge and in order to generate effective innovations.
