Unobserved firm heterogeneity and the size-exports nexus: Evidence from German panel data

This paper starts from the stylized fact that firm size and exporting tends to be positively related. Using large sets of establishment panel data for three different industries from official statistics, evidence is presented that the familiar picture of an export/sales ratio that increases (at a decreasing rate) with firm size vanishes if unobserved firm heterogeneity is controlled for in a fixed-effects fractional logit regression model. This finding is well in line with the fact that many small firms are “hidden export champions.” JEL no. F10, D21, L60     

Skilled-Labor Intensity Differences Across Firms,Endogenous Product Quality,and Wage Inequality

This paper proposes a theory to explain the relative wage-rate increase for skilled labor that results from trade liberalization that relies on within-sector reallocations of production resources (skilled and unskilled labor) across firms. Motivated by some stylized facts, in a model with firm heterogeneity, including firms that differ in their skill intensity even within a narrowly defined industry, firms with relatively high skill intensity that are more likely to be exporters, and a positive association between a firm’s skill intensity and its product quality, I develop a general equilibrium model where firms with a higher skill intensity endogenously choose a higher-quality product, and tend to be more profitable. In this framework, a reduction in trade costs allows members of the workforce to reallocate to more efficient firms that produce higher-quality products, using their skilled labor more intensively, resulting in a rising skill premium. The main sources of the increasing wage inequality that followed trade openness are a positive link between a firm’s skill intensity, its product quality, and quality competition.     

Firm Size and Work Compensation in China

Remarkably, recent research on the Chinese labor market has suggested that the situation in China is inconsistent with the stylized fact that large firms pay higher wages and offer more generous benefits. Expanding the empirical basis from 78 to 300 000 industrial firms, I overturn theprevious result andshow that wage determination in the averagefirmfits the international norm. Exploring subsamples of firms I also point to a likely source for the conflictingfindings： firm size is positively correlatedwith the average wage in private firms, but negatively correlated with the average wage in the state-owned sector. These novel results couM guide future studies aiming to understand the sources of the firm size wage premium, and, in particular, studies that target the largest industrial labor market in the world     

The Valuation Effect of Accounting Standard 158 on Firms with High and Low Financial Risk

SFAS 158 mandated balance sheet disclosure of the funded status of firms’ Defined Benefit Pension Plan using the Projected Benefit Obligation (PBO) to estimate the pension liability. SFAS 158 caused a market phenomenon because the use of the PBO engendered dramatically higher estimates of pension liability and hence the perception of risk. Our work focuses on two aspects of this change in pension accounting: first, how will industry firms change their accounting strategy in light of the new rules, and second, how will firms’ stock prices be affected by the new allegedly better estimate of pension liability? Our research suggests that firms’ accounting strategies changed in that they use higher discount rates to estimate pension liability which offset the dramatic impact of using the PBO. In addition, we find that high financial risk firms’ tendencies to use higher discount rates increase with the firms’ leverage and decrease with liquidity. To test the market reaction we utilize standard event study methodology to investigate the effects of SFAS 158 on stock returns. Our findings suggest that firms with high (low) financial risk earn negative (positive) abnormal returns on and around relevant event dates preceding the implementation of SFAS 158.     

Offshoring, domestic outsourcing and productivity: evidence for a number of European countries

The growth in offshoring and its economic effects have been subject to extensive empirical analysis. Yet, many studies have not distinguished accurately between offshoring, domestic outsourcing, and supplier changes. The present study provides stylized facts on offshoring in Europe between 1995 and 2008 taking into account this distinction. This study shows that service activities have been systematically offshored and outsourced domestically during this period, whereas manufacturing activities have been systematically offshored or moved from domestic to foreign suppliers. Overall the share of internal production has gone down by 4.5 percentage points, which raises the question whether firms have achieved productivity gains through this specialisation effort. Combining industry-level data on offshoring and domestic outsourcing with a firm panel, this study finds that service offshoring and offshoring of non-core manufacturing activities have contributed to an increase in productivity, whereas no statistically significant link is found for offshoring of core manufacturing activities and domestic outsourcing. The estimated productivity gains are found to be driven in particular by the gains of multinational firms.     

More-money and less-cash effects of diversification: Evidence from Japanese firms

This study provides evidence for the more-money and less-cash effects of diversification based on the industry-adjusted debt and cash holdings of Japanese firms. Diversified firms are more leveraged while holding less cash than focused firms in the same industries, even after controlling for the standard determinants of capital structure, unobserved heterogeneity, and the endogeneity of firm scope. The study also finds that these effects are mitigated when a firm has an ownership structure that insulates managers from capital market pressures for risk-taking. This pattern suggests that the risk-taking incentives of managers differentiate the effect of diversification on finance across firms.     

Innovation and exporting: evidence from Spanish manufacturing firms

This paper investigates the relationship between innovation and the export behavior of firms using data from a representative panel of Spanish firms over 1991–2002. It presents a simple theoretical model of the firm decision to export and innovate that guides the econometric analysis. Consistent with the predictions of the theoretical model, the econometric results suggest a positive effect of firm innovation on the probability of participation in export markets. The results further reveal the heterogeneous effects of different types of innovations on the firm export participation. In particular, product upgrading appears to have a larger effect on the firm export participation than the introduction of cost-saving innovations. These findings are robust to firm unobserved heterogeneity, dynamic specifications, and to the use of instrumental variables to control for the potential endogeneity between innovation and exporting.     

Patterns of China's industrialization: Concentration,specialization, and clustering

This paper presents a few stylized facts on the patterns of China's industrialization by computing a set of multi-dimensional measures on industrial concentration, regional specialization, and clustering based on census data at the firm level in 1995 and 2004. Our results show that China's rapid industrialization is characterized by the following patterns: industries have become more spatially concentrated; regions have become increasingly specialized; and firms have become more interconnected, both within industries and within regions. In addition, the number of firms is growing faster in clustered areas than non-clustered ones. Together these patterns suggest that China's industrialization process is largely cluster-based—a phenomenon in which a large number of highly interconnected firms are located within a well-defined geographic region.     

Aging Workforce,Firm Productivity and Labor Costs in Korea: Are Older Workers Costly to Firms?

Are older workers costly to firms? This study aims to investigate the relationship between an aging workforce on firm productivity and labor costs using a unique Korean firm‐level panel dataset (WPS) covering the period from 2007 to 2011. The primary results show no evidence of a negative relationship between the proportion of older workers and firm productivity, and no significant relationship between the proportion of older workers and labor costs. In addition, the findings of this study implies that failure to account for unobserved firm heterogeneity and endogeneity of changes in age structure biases the results toward finding a correlation between the age structure of workers and firm productivity and labor costs. Consequently, there is a tendency to underestimate the true value of older workers for firms.     

Endogeneity and the Dynamics of Voluntary Disclosure Quality: Is there Really an Effect on the Cost of Equity Capital?*

Research on the effects of voluntary disclosure quality on the cost of equity capital is often plagued by endogeneity concerns. In this paper, I use a dynamic panel system GMM estimator, which provides internal instruments from the firm's history that directly address endogeneity arising from unobserved heterogeneity and simultaneity. By using hand-collected voluntary disclosure scores for firms listed in the Swiss stock exchange, I examine the dynamic relation between voluntary disclosure quality and the cost of equity capital in a panel over a period of 10 years. The results suggest that the relation between voluntary disclosure quality and the cost of equity capital becomes insignificant after controlling adequately for potential dynamic endogeneity, simultaneity, and unobserved heterogeneity.     

The exporter productivity premium along the productivity distribution: evidence from quantile regression with nonadditive firm fixed effects

A vast literature on the international activities of heterogeneous firms finds the existence of a positive exporter productivity premium. On average, exporting firms are more productive than firms that sell on the national market only. The Melitz (Econometrica 71:1695–1725, 2003) model, however, has implications for not only mean differences but also differences in the distribution of productivity. Furthermore, exporting firms may be different from non-exporting firms for reasons that are not included in the Melitz model. We believe that conditioning on firm fixed effects and studying the distribution of productivity are both necessary for empirical tests of the Melitz model. This paper is the first to employ a new quantile estimation technique for panel data introduced in Powell (Did the economic stimulus payments of 2008 reduce labor supply? Evidence from quantile panel data estimation. RAND Corporation Publications Department, Santa Monica, 2014). We find that the premium is positive at all productivity levels, but highest at the lowest quantiles. These results support theoretical models which suggest that there is a division in productivity between exporters and non-exporters.     

Public debt and economic growth – economic systems matter

Most studies on the relationship between public debt and economic growth implicitly assume homogeneous debt effects across their samples. We –in accordance with recent literature– challenge this view and state that there likely is a great deal of cross-country heterogeneity in that relationship. However, other than scholars assuming that all countries are different, we expect that clusters of countries differ. We identify three country clusters with distinct economic systems: Liberal (Anglo Saxon), Continental (Core EU members) and Nordic (Scandinavian). We argue that different degrees of fiscal uncertainty at comparable levels of public debt between those economic systems constitute a major source of heterogeneity in the debt-growth relationship. Our empirical evidence supports this assumption. Continental countries face more growth reducing public debt effects than especially Liberal countries. There, public debt apparently exerts neutral or even positive growth effects, while for Nordic countries a non-linear relationship is discovered, with negative debt effects kicking in at public debt values of around 60% of GDP.     

How do firms combine different internationalisation modes? A multivariate probit approach

Most of the literature on the relationship between firm’s participation in international markets and firm heterogeneity focuses on export and foreign direct investment. This paper considers a wider range of forms of internationalisation that firms could combine into different patterns. With the purpose of analysing the selection of heterogeneous firms into different internationalisation patterns, we jointly model the decisions on the forms of internationalisation through a multivariate probit. This model allows us to avoid any a priori assumption about the firm’s behaviour. In this context we study the complementarity/substitutability relationships between forms of internationalisation. The results obtained show that: (i) neglecting some forms could lead to an incomplete representation about the firm’s internationalisation strategy, (ii) different firm’s characteristics influence the choice of internationalisation pattern, i.e. some types of firm are more prone to choosing one type of process over another, (iii) complementarity between forms of internationalisation seems to be preferred over substitution, but some heterogeneity also arises in this context.     

Trade policy uncertainty,development strategy,and export behavior: Evidence from listed industrial companies in China

On the basis of new structural economics theory and heterogeneity of firm viability, this study analyzes the effect of trade policy uncertainty on firm export behavior using panel data of Chinese listed companies in the industrial sector. Empirical results show that the high uncertainty of trade policy significantly inhibits the extensive and intensive margins of firm export, while heterogeneity effect occurs across firms with different levels of viability. The development strategy that violates comparative advantage strengthens the negative impact of trade policy uncertainty on firm export. Despite their correlation with viability, the type of ownership, total factor productivity, and long-term loan are not suitable proxies for firm viability. Under high uncertainty of trade policy, export market diversification can alleviate the restraining effect of development strategy on firm export, whereas firms in regions with high industrial-oriented development tend to be vulnerable to cost shocks, thus reducing export market diversification. Findings present important implications for emerging market countries to enact better international trade and economic policies.     

Import competition from and offshoring to low-income countries: Implications for employment and wages at U.S. domestic manufacturers

Using confidential linked firm-level trade transactions and census data between 1997 and 2012, we provide new evidence on how American firms without foreign affiliates adjust employment and wages as they adapt to import competition from low-income countries. We provide stylized facts on the input sourcing strategies of these domestic firms, contrasting them with multinationals operating in the same industry. We then investigate how changes in firm input purchases from low-income countries as well as domestic market import penetration from these sources are correlated with changes in employment and wages at surviving domestic firms. Greater offshoring by domestic firms from low-income countries correlates with larger declines in manufacturing employment and in the average production workers’ wage. Given the negative association, however, the estimated magnitudes are small, even for a narrow measure of offshoring that includes only intermediate goods. Import penetration of U.S. markets from these sources is associated with relatively larger changes in employment for arm’s length importing firms, but has no significant correlation with employment changes at firms that do not trade. Given differences in the degree of both offshoring and import penetration, we find substantial variation across industries in the magnitude of changes associated with low-income country imports.     

Exports versus FDI: An Empirical Test

In a recent paper Helpman, Melitz and Yeaple argue firm heterogeneity leads to self-selection in the structure of international commerce. Only the most productive firms find it profitable to meet the higher costs associated with FDI; the next set of firms finds it profitable to serve foreign markets through exporting; while the least productive firms serve only the domestic market. The paper tests this assumption using the concept of stochastic dominance. Robust support is found for the model, the productivity distribution of multinational firms is found to dominate that of export firms, which in turn dominates that of non-exporters. JEL no.

Firm Productivity and Mode of Foreign Expansion: Evidence from Taiwanese Manufacturing Firms

This paper builds on the recent literature on firm heterogeneity in international trade and foreign direct investment (FDI), and aims to empirically examine how firm productivity affects a firm’s foreign market entry strategy beyond the simple binary choice between exporting and FDI. Utilizing the panel data of Taiwanese manufacturing firms during 2002–2012, we further classify FDI methods by whole ownership or a joint venture to investigate a firm’s foreign expansion decision. By performing Kolmogorov–Smirnov (KS) tests, we find that if a firm is more productive, it is more likely to choose FDI rather than exporting. However, productivity of firms choosing whole ownership is not so different from choosing a joint venture. Furthermore, a more productive firm is more likely to conduct both whole ownership of the foreign subsidiary and a joint venture formation in the case of FDI.     

The reverse home-market effect in exports: a cross-country study of the extensive margin of exports

Do small countries have higher proportions of firms that export in manufacturing industries than large ones? As small countries are well known to be more open than large ones, it may appear uncontroversial to claim that the answer is yes. Nevertheless, this contradicts predictions from many standard trade models positing a home-market effect in the number of manufacturing firms and exporters. In this article, I present a theoretical model where a home-market effect in the number of firms coexists with a reverse home-market effect in the number of exporters: as in standard models, the number of firms in a small country relative to that in a large one is lower than relative income, but, in contrast to standard models, the relative number of exporters is larger. As a consequence, small countries will have higher proportions firms that export in manufacturing industries—a claim I support empirically.
