Network effects,trade, and productivity

We consider network effects in the monopolistically competitive model of trade developed by Melitz and Ottaviano (2008). We show that a larger network effect intensifies competition by allowing more‐productive firms to raise prices and earn higher profits, but forcing less‐productive firms to reduce prices and earn lower profits. As a result, low‐productivity firms are driven out of the market. We also show that when network effects are asymmetric, it may be difficult for firms from a country with a small network effect to compete with firms from a country with a large network effect.     

Gender earnings gap: the role of firm specific effects

The gender earnings differential is an intensely studied issue in labour economics. However, existing studies do not examine how the wage policies of firms affect gender earnings differentials. This paper uses employer–employee linked data to address this issue. The Juhn et al. [Juhn, C., Murphy K., Pierce, B., 1991. Accounting for the slowdown in black–white wage convergence, in M.H. Kosters, ed. Workers and Their Wages, AEI Press, 107–143] decomposition methodology is extended to incorporate the decomposition of firm fixed effects. It is found that, on average, firms' wage policies are associated with a significant narrowing of the gender earnings gaps. Further analysis indicates that firms which are more likely to have narrower gender earnings gaps are those subject to strong market competition, find it easy to identify labour productivity at the individual level, and with no enterprise level wage bargaining.     

Productivity, returns to scale and product differentiation in the retail trade industry: an empirical analysis using Japanese firm-level data

This paper examines productivity and returns to scale under the assumption of monopolistic competition using Japanese firm-level data. Although differentiating products (services) is considered important in firms?? strategies and productivity growth, it has not been sufficiently investigated in previous studies. In this paper, we study this issue in two retail trade industries, department stores and supermarkets, applying the model of Melitz (2000). Our results indicate that the standard production function is not relevant to estimate productivity in imperfectly competitive markets. It also suggests that the market structure should be carefully considered in productivity analysis. In addition, product differentiation has a positive effect on firms?? revenue for the supermarkets. Furthermore, the retail trade industries possibly follow increasing returns to scale. Thus, policy measures that promote economies of scale and product differentiation should contribute to further growth in these industries. In addition, the results indicate that the regulatory reform of the retail trade industry in 2000 increased the gap between winners and losers in terms of productivity.     

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.

     

Monopsonistic competition for the “best” workers

In this paper we analyse an economy where firms use labour as the only production factor, with constant return to scale. We suppose that jobs differ in their non-wage characteristics so each firm has monopsonistic power. In particular, we suppose that workers are heterogeneous with respect to their productivity. Then, each firm has incentives to offer higher wages in order to recruit the most productive workers. Competition among firms leads to a symmetric equilibrium wage, which is higher than the reservation wage, and to involuntary unemployment for the less productive workers, who are willing to work at the current wage but are not hired because their productivity is lower than the wage level. If firms have no institutional constraint on paying lower wages for the same job, an endogenous labour market segmentation emerges.     

Firm turnover and productivity differentials in Ethiopian manufacturing

Are the forces of market selection at work in Africa? How successful are markets in these economies in sorting out firms on an efficiency basis following the sequence of reforms to liberalize and particularly to transform some of the previous command economies to market oriented ones? What is the pattern of entry and exit in the manufacturing sector and how does it affect industry productivity growth? This study examines these issues using firm-level industrial census data from the Ethiopian manufacturing sector. It is the first attempt to analyze firm turnover and productivity differentials using industrial census data in sub-Saharan Africa. The Ethiopian manufacturing sector exhibits a high firm turnover rate that declines with size. Exit is particularly high among new entrants; 60% exit within the first 3 years in business. Our study consistently shows a significant difference in productivity across different groups of firms, which is reflected in a turnover pattern where the less productive exit while firms with better productivity survive. We also found higher aggregate productivity growth over the sample period, mainly driven by firm turnover.     

The effects of innovation–cost strategy, knowledge, and action in the supply chain on firm performance

Despite the importance of supply chains within today's economy, we know little about how the knowledge of supply chains can contribute to superior performance at the firm level. Building on the resource-based view, knowledge-based view and strategic choice theory, we develop hypotheses linking two knowledge-driven supply chain phenomena (i.e., knowledge development capacity and intellectual capital), innovation–cost strategy, and action to firm-level performance. Using survey and archival data from 489 firms, we found that performance is influenced by how well knowledge development capacity and intellectual capital efforts complement alternative chain strategies. More specifically, each strategy type requires different constellations of knowledge development capacity and intellectual capital to enhance action and create superior firm performance. These results highlight the importance of supply chain phenomena for firm-level performance, and more broadly, the value of supply chains as a competitive weapon in contemporary firms.     

Knowledge capital,CEO power,and firm value: Evidence from the IT industry

Disruptive innovation dramatically changes the demand of a product market in the information technology (IT) industry. In response to the impact of disruptive innovation, IT firms that may be eliminated from the competitive race actively develop innovative products and adjust their operating strategies to strengthen their survivability in the fiercely competitive market. Thus, this study explores the factors that affect firm value in the IT industry under the impact of disruptive innovation. The empirical results reveal that knowledge capital and CEO power play crucial roles in explaining firm value. IT firms with powerful CEOs and increased knowledge capital have high firm values. The effects of knowledge capital and CEO power on firm value are especially significant for founder and duality CEO firms. Furthermore, the influence of CEO power is more prominent in periods of financial crisis.     

Wage Bargaining in Industries with Market Power

We develop a game-theoretic version of the right-to-manage model of firm-level bargaining where strategic interactions among firms are explicitly recognized. Our main aim is to investigate how equilibrium wages and employment react to changes in various labor and product market variables. We show that our comparative statics results hinge crucially on the strategic nature of the game, which in turn is determined by the relative bargaining power of unions and managers.     

Linking employer branding orientation and firm performance: Testing a dual mediation route of recruitment efficiency and positive affective climate

Faced with competitive labor markets, firms increasingly use employer branding to build a qualified workforce and engage their employees. However, our understanding of the impact of employer branding orientation on firm performance and the theoretical firm-level mechanisms underlying this potential impact is very limited. To address this gap, we integrate brand marketing theory with human resource management (HRM) research to develop a model explicating how employer branding orientation is linked to firm performance through a dual route by enhancing both recruitment efficiency (i.e., external route: applicants) and positive affective climate (i.e., internal route: incumbent employees). The results of a multisource study (i.e., top management, human resource managers, employees) with 93 firms show employer branding orientation is positively related to firm performance through positive affective climate but not recruitment efficiency. Using a brand equity approach to HRM, our results advance the literature by demonstrating the generalizability of employer branding effects independent of concrete brand attributes and explaining the firm-level mediating mechanisms linking it to firm performance.     

Do credit squeezes influence firm survival? An empirical investigation of China

This paper analyses the effect of a “credit squeeze” policy that was set by the Chinese government in 2007, increasing the strictness for firm-level bank loans. We adopt the difference-in-difference (DID) model to compare the survival rate change before and after the policy was implemented. We further explore the mechanism behind how the “credit squeeze” policy reduced the probability of firms surviving the market from perspectives such as financial constraints and ownership structures. The “credit squeeze” policy significantly increased firms’ operating costs and lowered firms’ productivity. In addition, we find that the zombie firm phenomenon existing in state-owned enterprises has a large impact on our estimation. Our results provide practical policy implications regarding the compromise between systematic debt risk and firm survival.     

Ownership,firm size and rent sharing in Bulgaria

Using a unique three-digit firm-level data set of all medium and large manufacturing enterprises in Bulgaria covering the years 1997–1998, we investigate how wages are affected by ownership status, firm size and rent sharing. Our pooled OLS, panel and first-difference TSLS estimates clearly point to ownership structure as an important determinant of both the wage level (for given productivity) and the degree of rent sharing. Rent sharing is very pronounced in state-owned firms but far less pronounced in private domestic and foreign firms. The results strongly confirm the existence of a multinational wage premium. In addition, we find weak evidence of a positive firm size-wage effect and a positive effect of firm size on the degree of rent sharing. If these effects exist, they are often more pronounced in private domestic firms.     

Broad-based stock options: before and after the market downturn

We examine labour productivity in small, medium and large firms that broadly distribute stock options under starkly different market conditions – during the bull (1995–7) and bear (2000–2) stock markets. We find greater labour output in both upward and downward markets in all firm size categories, with the exception of small firms in a declining market, where the productivity is also greater, but the statistical significance of the result is weak.     

Job mobility and the gender wage gap in Italy

This paper investigates the contribution of gender differences in job mobility to the emergence of a gender wage gap in the Italian labour market. We show that over the first 10 years of labour market experience job mobility accounts for up to 30% of total log wage growth for men and only 8.3% for women, and that this difference is mainly due to differences in returns to mobility. The gender mobility gap is robust to the inclusion of individual, job and firm characteristics, to different ways of accounting for individual unobserved heterogeneity, and is mainly found for voluntary job moves. Looking at the characteristics of the jobs and the firms' workers move to, we find that moves to larger firms represent by far the main source of gender differences in returns to mobility. We offer two possible explanations for this finding; one which involves differences in bargaining behaviour and one which relates to the theory of compensating differentials.     

The need for speed: impacts of internet connectivity on firm productivity

Broadband access is widely considered to be a productivity-enhancing factor, but there are few firm-level estimates of its benefits. We use a large micro-survey of firms linked to longitudinal firm financial data to determine the impact that broadband access has on firm productivity. Propensity score matching is used to control for factors, including the firm’s own lagged productivity, that determine a firm’s internet access choice. Instrumental variables estimates are employed as a robustness check. Results indicate that broadband adoption boosts firm productivity by 7–10%; effects are consistent across urban versus rural locations and across high versus low knowledge intensive sectors.     

Panel data estimates of the production function and product and labor market imperfections

Consistent with two models of imperfect competition in the labor market—the efficient bargaining model and the monopsony model—we provide two extensions of a microeconomic version of Hall's framework for estimating price‐cost margins. We show that both product and labor market imperfections generate a wedge between factor elasticities in the production function and their corresponding shares in revenue, which can be characterized by a ‘joint market imperfections parameter’. Using an unbalanced panel of 10,646 French firms in 38 manufacturing industries over the period 1978–2001, we can classify these industries into six different regimes depending on the type of competition in the product and the labor market. By far the most predominant regime is one of imperfect competition in the product market and efficient bargaining in the labor market (IC‐EB), followed by a regime of imperfect competition in the product market and perfect competition or right‐to‐manage bargaining in the labor market (IC‐PR), and by a regime of perfect competition in the product market and monopsony in the labor market (PC‐MO). For each of these three predominant regimes, we assess within‐regime firm differences in the estimated average price‐cost mark‐up and rent sharing or labor supply elasticity parameters, following the Swamy methodology to determine the degree of true firm dispersion. To assess the plausibility of our findings in the case of the dominant regime (IC‐EB), we also relate our industry and firm‐level estimates of price‐cost mark‐up and extent of rent sharing to industry characteristics and firm‐specific variables respectively.

Product configuration,ambidexterity and firm performance in the context of industrial equipment manufacturing

The practice of configuring products to individual customer orders has found application in a variety of industry contexts, but little is known about the specific capabilities that firms develop to successfully compete when offering configurable products. Our research begins to fill this gap in the context of industrial equipment manufacturing. Drawing from the ambidexterity literature, we argue that firms have to balance dual goals of reducing variation and promoting variation in their product configuration activities by fostering two distinct firm-level capabilities: product configuration effectiveness (PCE) and product configuration intelligence (PCI). Specifically, we hypothesize that the simultaneous presence of PCE and PCI—that is, product configuration ambidexterity (PCA)—drives superior firm responsiveness and, indirectly firm sales and operating margin. However, we also contend that responsiveness gains through PCA can diminish with product complexity and can increase operating cost. We test these hypotheses by collecting both primary and secondary data from a sample of 108 European industrial equipment manufacturing firms. Results from our analyses indicate that PCA has an indirect effect through responsiveness on sales and operating cost but not on operating margin, with this effect diminishing with product complexity. Taken together, our results suggest that investment in developing PCA may represent a conundrum for industrial equipment manufacturing firms, because it translates into market but not financial advantages, and it is intertwined with product design decisions. We conclude this study with a discussion of the findings for theory and practice.     

The efficiency of training and hiring with intrafirm bargaining

This paper demonstrates that firms hire and train workers efficiently in a matching and intrafirm bargaining economy when the Hosios condition holds and returns to scale are constant. This conclusion stands in contrast to the prevailing view that training costs are a source of inefficiency in imperfect labor markets. The efficiency of the competitive economy relies on the ability of large firms to take into account the negative impact of the training rate on the wages negotiated inside the firm through intrafirm bargaining: untrained workers accept a wage reduction in compensation for potential training that is accessible only following employment. This intrafirm bargaining process solves efficiency problems associated with training costs that would otherwise lead to inefficient hiring and training decisions. This conclusion holds true for both specific and general human capital.     

Holdup in oligopsonistic labour markets - a new role for the minimum wage

We consider a labour market model of oligopsonistic wage competition and show that there is a holdup problem although workers do not have any bargaining power. When a firm invests more, it pays a higher wage in order to attract workers from competitors. Because workers participate in the returns on investment while only firms bear the costs, investment is inefficiently low. A binding minimum wage can achieve the first-best level of investment, both in the short run for a given number of firms and in the long run when the number of firms is endogenous.     

Overeducation, wages and promotions within the firm

We analyse data from personnel records of a large firm producing energy and telecommunication and test for the effect of deviations between required and attained education of workers. Required education is measured as hiring standards set by the firm. We find the usual effects of over- and undereducation in a wage regression, thus rejecting the argument that such effects are exclusively due to firm fixed effects. Distinguishing, within the firm, between a sheltered internal labour market and an exposed external labour market, we find that at the internal labour market over- and undereducation significantly affect career development, in particular at younger ages, but that such effects are mostly absent at the firm's external labour market.
