Firm Productivity,Innovation, and Financial Development

How do firm‐specific actions—in particular, innovation—affect firm productivity? What is the role of the financial sector in facilitating higher productivity? Using a rich firm‐level data set, we find that innovation is crucial for firm performance as it directly and measurably increases productivity. The impact of innovation on productivity is larger in less‐developed countries. Evidence of financial sector development influencing the innovation‐productivity link is weak, but the effect is difficult to identify due to correlation between indicators of a country's financial and nonfinancial development. Furthermore, we find evidence that the innovation effect on productivity is more significant for high‐tech firms than for low‐tech firms.     

Productivity Growth in Different Plant‐size Groups in the Malaysian Manufacturing Sector*

In the present study, we develop a stochastic frontier production model that allows for different groups of firms to have different patterns of technical efficiency over time. We apply our model to the Malaysian manufacturing sector to decompose total factor productivity growth into technical efficiency change and technical progress for different plant size groups (e.g. large and small) in seven industries during 2000–2004. Our empirical results indicate that technical efficiency has worsened across all industries and plant‐size groups. In contrast, we find evidence of substantial technical progress in all industries. In fact, technical progress has been larger than technical efficiency deterioration in most industries and plant‐size groups, leading to total factor productivity growth. Our analysis identifies the industries and plant‐size groups that lag the most in terms of productivity, and thus have the greatest scope for policies that facilitate productivity growth.     

Foreign direct investment and technology spillovers: Which firms really benefit?

Foreign direct investment is thought to contribute to host economies by increasing their efficiency either directly or through technology diffusion. Such efficiency benefits are neither equally produced by foreign firms nor equally distributed to all domestic firms. The special question addressed in this study is related to how differentiated such effects are depending on size and degree of (foreign) ownership. Based on a sample of 3,742 manufacturing firms operating in Greece in 1997, it is found that, while it is large, majority-held foreign firms that exhibit higher productivity, spillovers are important for small domestic firms and stem mostly from small joint ventures where the foreign partner owns a minor part of equity.

进口中间品质量与企业生产率:基于中国制造业企业的研究

文章基于2000-2006年中国工业企业数据和海关贸易数据,测算了进口中间品质量和企业全要素生产率,并深入分析了进口中间品产品质量对中国制造业企业全要素生产率的影响。多种计量方法的分析结果表明:进口中间品产品质量显著促进了企业生产率的提升。异质性分析的结果表明,进口中间品产品质量对加工贸易企业、外资企业的生产率提升作用显著大于其他贸易方式和所有制类型的企业;不管企业是从非OECD国家进口,还是从OECD国家进口,中间品产品质量的提升都可促进企业生产率的提高;相比高质量的进口中间品,低质量的进口中间品不能提高企业的生产率。进一步的分位数回归结果表明,相比高生产率企业,低生产率企业能够从进口中间品质量中获益更多,全面提高进口中间品质量可以自动地缩小企业间生产率水平的差距。     

Pass-on trade: why do firms simultaneously engage in two-way trade in the same varieties?

This paper documents that a large fraction of trade flows at the firm level consists of simultaneous imports and exports in identical products, narrowly defined at the 8-digit product classification, which we call pass-on trade (POT). We use data on imports and exports at the firm and product level for Slovenian manufacturing firms in the period 1994–2008, to show that, on average, 70 % of all exporting firms engage in POT. This corresponds to more than 50 % of all exported products. Thus, imported products that are exported again by the same firm is a statistical regularity of trade of Slovenian manufacturing firms. We document that the use of POT is increasing in firm size, product diversification, multinational status as well as firm productivity and profitability. We offer and explore empirically a number of explanations for POT. Among possible explanations, we find evidence on the importance of firms’ multinational networks and demand complementarities between firms’ own and POT products. The latter confirms the theoretical explanations for carry-along trade (CAT) as developed by the recent work of Bernard et al. (2012).     

Do Female Managers Affect Productivity? Evidence from Zimbabwean Manufacturing Firms

Using a large dataset of Zimbabwean manufacturing firms extracted from the two waves of World Bank Enterprise Surveys of 2011 and 2016, the study investigates the impact of female management on firm's productivity in Zimbabwe's manufacturing firms. The study estimates a modified production function, to incorporate gender dimension, using a random effects estimation model. The results show that the effect of having a female manager on firm productivity varies by geographical location in the case of Zimbabwe. Specifically, the productivity of firms which have a female top manager, and are located in Harare, experience a negative productivity differential as they significantly reduce their productivity gap by 9.9 percent. On the other hand, the study found that having a female top manager in manufacturing firms located in Bulawayo significantly increases productivity by 7.9 percent compared to firms located in the Midlands area. We also find that the effect of a female manager on firm productivity differs by sectors, stressing the need for domestic economic policy to consider these dynamics. Given the importance of location in determining the contribution of a production manager on firm performance, the government may need to implement policies that consider location‐specific factors to enhance productivity of the manufacturing sector of Zimbabwe.     

Effects of Knowledge Spillovers on Knowledge Production and Productivity Growth in Korean Manufacturing Firms

Using Korean firm‐level data, this paper studies the effects of knowledge spillovers on knowledge production and productivity growth. Data from 213 Korean firms for the years 1985 to 2007 are used, and the number of patent applications is used as a proxy variable for knowledge. The results show that all the growth rates of output, patents, and productivity are higher in high‐technology firms. Regression results show that the spillover effect on knowledge production and productivity growth is very significant, and that the spillover effect is larger in small firms than in large firms. Moreover, spillover effects on productivity growth are larger after 1995, when Korean intellectual property rights were strengthened. Our findings suggest that the effects of knowledge spillover on productivity are positively correlated with strong intellectual property rights.     

Entry and the accumulation of capital: A two state variable extension to the Ramsey model

In this paper we consider the entry and exit of firms in a dynamic general equilibrium model with capital. At the firm level, there is a fixed cost combined with increasing marginal cost, which gives a standard U‐shaped cost curve with optimal firm size. Entry is determined by a free entry condition such that the cost of entry is equal to the present value of incumbent firms. The cost of entry (exit) depends on the flow of entry (exit). Equilibrium is saddle‐point stable and the stable manifold is two‐dimensional. Transitional dynamics can, under certain circumstances, be non‐monotonic.     

The impact of differential power pricing policy on firm productivity in China: Evidence from iron and steel firms

The differential power pricing (DPP) policy is implemented as an important measure to curb the unrestrained development of high-energy-consuming industries, optimize industrial structure, and promote the upgrading of industrial technology. However, it is unclear how the DPP policy affects the productivity of regulated firms. Using the difference-in-differences approach, this study is the first to investigate empirically the DPP policy’s impact on the productivity of China’s iron and steel firms—a top carbon emitter. The results show that the DPP policy has a significant negative effect on the productivity of iron and steel firms, leading to a 1.20% per annum decrease in the total factor productivity growth of these firms, primarily because the policy significantly hinders firms’ scale efficiency. Considering the heterogeneity of firms, the impeding impact on large-scale and state-owned firms is less than that on the firms of full sample. To curb the irrational expansion of energy-intensive industries and eliminate backward production capacity, the government should implement the DPP policy more precisely according to the heterogeneity of firms, and other auxiliary measures, such as cost compensation for innovation, are also recommended.     

Product differentiation,export participation and productivity growth: Evidence from Chinese manufacturing firms

In this paper, we investigate how the degree of export participation and product differentiation affect firms' productivity growth through learning-by-exporting. We extend the model of Melitz and Ottaviano (2008) to endogenize the effort firms allocate to learning. This effort choice depends on both the degree to which firms enter export markets and the extent to which products are differentiated across producers. Using a firm-level dataset from China's manufacturing industries, we implement propensity score matching methods to test the model's predictions. Our results indicate that the degree of export participation is positively correlated with TFP improvements. Simultaneously, we empirically verify that firms exporting less differentiated products experience faster TFP growth than those exporting more differentiated products.     

Pollution control and foreign firms’ exit behavior in China

China faces a common dilemma of how to maintain rapid economic growth while also reducing the pollution that has accompanied growth. Will stricter pollution controls drive away the foreign firms that have helped spur growth in China? This paper studies the effects of the Two-Control-Zone (TCZ) pollution control policy on foreign firms’ exit behavior in China. Based on firm-level data from 1998 to 2009, we find that foreign firms’ responses are not significantly different from domestic firms on average once environmental regulations impose an added cost of business. However, foreign firms’ responses to stricter pollution controls tend to differ based on various firm characteristics. Our estimation indicates that larger size, higher productivity and exporting all make foreign firms less likely to exit than similar domestic firms in regions with stricter pollution control.     

Environmental regulation,firm heterogeneity,and intra-industry reallocation

We describe a model with firm heterogeneity and endogenous pollution abatement to show how emission intensity and exit/entry selections vary across firms. Using Chinese firm-level emission and production data, we find evidence that low productivity firms have higher emission intensity. The emission intensity of firms with productivity below 10 percentile is 5.26 times larger than firms with productivity above 90 percentile. Combining the Annual Survey of Chinese Industrial Enterprises (CIE) data, and applying a triple-difference research design, we find that firms with high emission intensity or low productivity have a higher probability of exit when exposed to strict environmental policy. We also find the exit of unproductive firms contributes to aggregate productivity and strict environmental policy can help to reduce misallocation.     

Multi-product firms,product mix changes and upgrading: Evidence from China's state-owned forest areas

Product selection matters for a firm's productivity and long-run growth. Recent theoretical and empirical studies indicate that an important margin of adjustment to policy reforms is the reallocation of output within firms through changes in product mix decisions. This paper examines the frequency, pervasiveness and determinants of product-switching and upgrading activities in firms located in China's state-owned forest areas during a period of gradual institutional and managerial reforms (2004–2008). We find that changes to the product mix are pervasive and characterized by adding or churning products rather than only shedding products. Moreover, changes in firms’ product mix have made a significant contribution to the aggregate output growth during our sample period. We also find that firms with different characteristics, human capital and market conditions differ in their propensity to diversify and upgrade product mix.     

Does gender structure affect firm productivity? Evidence from China

This study examines the impact of gender workforce composition on firm productivity. Using a large sample of Chinese manufacturing firms and conditional on human capital-related controls, we find that firms with a greater share of female workers demonstrate lower productivity. However, our results suggest that increasing the fraction of highly educated female workers significantly improves firm performance. This effect is evident for all private firms regardless of their trade orientation and foreign firms undertaking purely domestic sales. However, the effect does not exist in the case of state-owned and export-oriented foreign enterprises. Compared with medium-sized and large firms, small firms benefit more from gender diversity at high education level. Finally, the share of highly talented female workers indicates better firm performance in more feminized industries.     

Imported Capital Goods and Manufacturing Productivity: Evidence from Botswana's Manufacturing Sector

This article examines the effects of imported capital goods on manufacturing productivity growth in Botswana. Despite consistent efforts aimed at diversification, Botswana's economy has remained heavily dependent on diamond exports, and the country's productivity remains a point of concern. The ability to apply foreign technologies to increase productivity and spur diversification is limited by the foreign exchange gap. This study uses an imported input growth model to analyse how the importation of capital goods contributes to enabling productivity growth and export diversification. With a panel of 340 manufacturing firms, the study also analyses the effects of imported capital goods on firm productivity growth and skills development. The results show that imported machines and equipment have increase manufacturing productivity after 1‐2 years following the investment. Additionally, foreign‐owned firms were found to enjoy more productivity growth than their domestic counterparts.

The determinants of export performance: A firm-level study of Italian manufacturing

The Determinants of Export Performance: A Firm-Level Study of Italian Manufacturing. — This paper analyzes some determinants of a firm’s probability of exporting and export intensity and presents the findings of an empirical study carried out on a large sample of Italian firms. On the basis of Probit and Tobit estimates, it emerges that these determinants change according to the size of firms. In particular, only for small firms is the relationship between size and export performance positive. The export activity of small and medium-sized firms decreases with the share of sales due to subcontracting. Larger firms, instead, benefit more from being affiliated with business groups and performing innovative activities of a different nature.     

Firms’ exporting and importing activities: is there a two-way relationship?

The literature on firm heterogeneity and trade has highlighted that most trading firms tend to engage in both importing and exporting activities. This paper provides some evidence that helps understanding to what extent this is the result of a two-way relationship. Using firm-level data for a group of 27 Eastern European and Central Asian countries from the World Bank Business Environment and Enterprise Performance Survey (BEEPS) over the period 2002–2008, we estimate a bivariate probit model of exporting and importing. After controlling for size (and other firm-level characteristics) we find that firms’ exporting activity does not increase the probability of importing, while the latter has a positive effect on foreign sales. This effect is mainly channeled through an increase in firm productivity and product innovation.     

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.     

Cross-country evidence on the allocation of COVID-19 government subsidies and consequences for productivity

We study the consequences of the Covid-19 pandemic and related policy support on productivity. We employ an extensive micro-distributed exercise to access otherwise unavailable individual data on firm performance and government subsidies. Our cross-country evidence for five EU countries shows that the pandemic led to a significant short-term decline in aggregate productivity and the direct support to firms had only a limited positive effect on productivity developments. A thorough comparative analysis of the distribution of employment and overall direct subsidies, considering separately also relative firm-level size of support and the probability of being supported, reveals ambiguous cross-country results related to the firm-level productivity and points to the decisive role of other firm characteristics.
