宏观经济不确定性、融资约束与企业现金持有行为——来自中国上市公司的经验证据

本文建立一个简化的存货缓冲模型来形式化管理者的现金持有决策,并基于中国非金融类上市公司2001-2009年间的面板数据,考察不同融资约束条件下宏观经济不确定性对企业现金持有行为的影响。研究发现,宏观经济不确定性对企业的现金持有水平具有显著的正向影响;相比于低融资约束的公司,高融资约束公司的现金持有水平对宏观经济不确定性变化具有更高的敏感性。研究结果有助于增进对中国制度情境下企业流动性需求行为的理解。     

Spillovers from agglomerations and inward FDI: a multilevel analysis on sub-Saharan African firms

This paper adopts multilevel analysis to study the agglomeration-performance nexus for domestic firms in sub-Saharan Africa. We show that contextual factors can explain up to 30 % of the variance in firms’ productivity, more than half of which depends on the geographic location. Our results show also that African firms’ productivity is positively correlated to the size of the agglomeration when they locate in larger cities specialized in different sectors, while the relation turns negative when they face direct competition from firms in the same industry. These effects are similar in the services and the manufacturing industries, even if in the latter positive spillovers are found to be conditional to the presence of backward and forward linkages with nearby firms. Finally, we are able to show that these effects are also confirmed when domestic firms locate close to foreign multinationals, especially those coming from the South.     

An empirical analysis of contracting by Chinese firms

Why do firms use formal contracts or relational contracts with their business partners? The paper uses survey data based on a large number of Chinese firms to uncover some important factors for why and when formal contracts or relational contracts are used. This study identifies geographical location as an important factor in affecting Chinese firms' contracting decisions. We find that a firm is more likely to use formal contracts with its clients and suppliers if they are located in a city different from the firm's main business location. We also find that larger (smaller) firms tend to adopt formal (relational) contracts. However, while the number of clients has a negative impact on a firm's adoption of formal contracts with its clients, the number of suppliers has a positive impact on its adoption of formal contracts with the suppliers.     

Impacts of increased Chinese imports on Japan’s labor market

Using the Japanese firm/establishment-level census data, we investigate the impact of the Chinese import penetration on employment in Japan. We found negative impacts of the Chinese import penetration on total employment, especially in industries producing competing products to Chinese imports, and a positive impact of the import penetration in the industries from which firms purchase their inputs (upstream import penetration). The negative impacts are mainly driven by firms’ exit from the market while positive impacts are enjoyed by surviving firms. We did not find any significant impacts of the penetration in the industries to which firms sell their products (downstream penetration).     

外资所有权与工资升水——来自中国制造业的证据

很多研究发现外商投资企业比内资企业对同等情况下的工人所付工资要高,本文利用中国省际制造业分大类数据对此进行了实证研究,研究的结果表明,在控制了各种对工资影响因素(产业、地区、企业、工人素质)后,外资所有权工资升水显著存在,大约为10%。同时还对平均薪酬进行了研究,外资所有权薪酬升水大约为7%。此外,本文还得出了其他一些有意义的结论。     

On-the-job training and productivity: Firm-level evidence from a large developing country

We investigate the effects of on-the-job training on firm productivity and wages using a large panel data set constituted of all large and medium size manufacturing firms in China over 2003–2007. We estimate firm productivity carefully with a recent semiparametric method and combine the propensity score matching and the difference-in-differences techniques to estimate the treatment effect of training. We find consistent evidence that i) training helps boost firm productivity and wages; ii) the higher the training expenditure per capita, the higher the increase in productivity and wages; iii) firms benefit more from training than workers. These findings are not sensitive to industrial capital intensity or firm ownership structure.     

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.     

Macroeconomic uncertainty,high-level innovation,and urban green development performance in China

This study incorporates macroeconomic uncertainty and high-level innovation into the framework of urban green development performance analysis. The positive impact of macroeconomic uncertainty on high-level innovation is related to the economic level and geographical location of cities. In developed cities and coastal cities, positive incentives for high-level innovation depicted by invention patents and green technology patents are generated, but the impacts are not significant in less developed cities. The negative impact of macroeconomic uncertainty on green development performance of developed and coastal cities is not significant, but it has a more obvious inhibition effect in less developed cities; raising the proportion of high-level innovation helps to weaken this negative impact.     

ISO认证与企业创新：地理位置与组织形式的调节效应

尽管已有研究在不同情境下广泛地检验了ISO认证所引致的绩效结果,但还未充分地关注中国企业ISO认证的相关议题。利用世界银行对中国企业的调查数据,实证检验ISO认证对企业创新的影响,以及地理位置和组织形式的调节效应。结果表明,ISO认证对产品创新与过程创新均产生显著的正向影响;相较于中西部地区的企业,东部地区企业的ISO认证对产品和过程创新的正向影响更加显著;相较于合伙制与公司制的企业,独资企业的ISO认证对产品和过程创新的正向影响更加显著。     

Small firm internationalization,innovation, and growth

This paper studies the effect of internationalization on innovation and firm performance (employment growth and sales growth) taking the interdependencies among the variables into account. Given the potential endogeneity, this study uses theory-driven instrumental variables and structural equation modelling to estimate the direct and indirect effects of internationalization. Firm-level data is obtained from a survey of 150 Dutch small firms that took part in an export promotion program. The main results show that internationalization has a positive impact on innovation. Internationalization increases firm performance directly and indirectly through innovation, while the direct impact of innovation on firm performance is insignificant. We contribute to the literature of export promotion programs as our results suggest that they not only increase small firm internationalization but also affect innovation and firm growth.     

Export Activity,Firm Size and Wage Structure: Evidence from Taiwanese Manufacturing Firms*

This study adopts a semiparametric smooth coefficient model to evaluate the export–wage premiums, firm size–wage premiums, and the wage gap between skilled and unskilled labor. Particular focus is placed upon widespread evidence indicating that pay levels in ‘large’ and ‘export‐oriented’ firms are higher than in their ‘small’ and ‘domestic‐oriented’ counterparts. Applying the firm‐level data for Taiwanese manufacturing firms, we find a positive export–wage premium for skilled workers and a negative export–wage premium for unskilled workers. The hypothesis of a constant export premium across firm size is rejected. While most of the export–wage premiums for skilled labor can be attributed to the small and medium firms, the large exporting firms have a significant adverse effect on wages for unskilled labor. Moreover, our results suggest that the firm size–wage premiums for skilled workers are larger than those for unskilled workers. The wage gap between the two skill groups is also sensitive to size categories.     

Market potential,firm exports and profit: Which market do the Chinese firms profit from?

This paper examines the effects of market potential on Chinese firms' exports and profit by using data from the Chinese industrial enterprise database and The China City Statistical Yearbooks during 1998–2007. We find that international market potential has positive effects on firm exports, but negative effects on firm profit, while domestic market potential has opposite impacts. This finding suggests that Chinese firms' profit mainly stems from the domestic market. Moreover, the adverse impact of international market potential on firm profit diminishes with the increase of firm productivity, and some firms with higher productivity may benefit from the expansion of foreign markets.     

Land costs,government intervention,and migration of firms: The case of China

By using unique firm relocation data in China, we first document the relocation behavior of Chinese firms and show that less government intervention (relative to market forces) can improve economic efficiency by facilitating industrial relocation which saves on costs. Ever since China joined the World Trade Organization (WTO) in 2001, investments have poured into the coastal region, which in turn, have almost tripled land costs in the major coastal cities. We exploit this land cost shock in the early 2000s to identify its effect on the relocation behavior of firms. Specifically, we instrument land price growth with the access of a city to foreign markets (approximated by distance to Shanghai), and then estimate the differential impact of land costs on firms regarding land reliance. Our major findings are as follows: (1) the migration rate of Chinese firms in China is on average 3.2%, (2) Rising land costs drive firms to migrate, and firms that use more land-intensive technology are more compelled to migrate, and (3) in regions where the local government intervention is stronger (the market is less developed), the relocation decision of Chinese firms is distorted in the sense that firms are less likely to relocate despite surging land prices due to government intervention.     

The Spillover effect of export processing zones

China has established many Export Processing Zones (EPZs) to support exports in a few industries with the support of local government. These industries can be defined as the pillar industries of an EPZ. We use a difference-in-difference approach to study the spillover effect of an EPZ on the adjacent firms outside the zone, using a sample of 42 Chinese cities with their first EPZs being founded during 2000–2005. We find that EPZs improve the performance of surrounding firms near the zone, with the impact being larger for firms in the pillar industries that the EPZs particularly favor. We also find that the magnitude of spillovers depends on the distance between a firm and the nearest EPZ: pillar-industry firms can receive higher premium by locating close to an EPZ, and this impact is the opposite for non-pillar industry firms. We examine the potential heterogeneous effects and find that the spillover effects are bigger for larger EPZs and EPZs designed to promote high-tech industries. We also find that domestic firms benefit more from the EPZ policy compared to their foreign counterparts.     

IT,enterprise reform,and productivity in Chinese manufacturing firms

This paper is a first attempt at examining the impact that Information Technology (IT) and enterprise reform have on the productivity of Chinese manufacturing firms by using large-scale firm level datasets from 1995 to 2002. It is found that enterprise reforms captured by the entry and exit of firms have had a positive impact on aggregated productivity growth. In addition, IT plays a relatively important role in the productivity performance of post-reform enterprises, as opposed to enterprises which are not affected by major restructuring in the course of Chinese state-owned enterprise reforms.     

Do Economic Effects Justify the Use of Fiscal Incentives?

The siting of a large, new firm is often presumed to give rise to significant economic and tax benefits to the community of location. This presumption serves as the basis for the granting of lucrative economic development incentives to footloose businesses. This article examines whether large, mobile firms generate significant net benefits for the region of location. Panel data and nonrandom estimation techniques are applied to a primary database of large firms that made location decisions in the 1980s to explore the impact of location on regional economic performance, The empirical analysis explores different treatment regions (both effects within the county and the metropolitan statistical area [MSA] of location) and different control regions. The results show that large firms fail to produce significant net benefits for their host communities, calling into question the high-stakes bidding war over jobs and investment.     

外资企业选址与企业生产率

本文利用Grossman-Helpman-Szeidl（2006）模型研究了外资企业在发展中国家内部的选址决策,模型表明：效率高的企业偏向选址于固定成本高可变成本低的地方,效率低的企业偏向选址于固定成本低可变成本高的地方。同时各个地区的效率空间会被运输成本所压缩。由于中国东部、中西部与东南亚国家之间劳动力工资以及固定投资成本的结构差异,高效率的企业会选址于印尼、菲律宾、越南三国,效率处于中间的企业会选址于中国中西部以及中国东部,效率最低的企业会选址于马来西亚、泰国两国。随后本文用2004-2013年Bvd亚太企业母公司层面面板数据验证了企业因效率不同而导致的选址差异。最后本文分析了双边自由贸易区对企业选址的效率空间的影响,研究表明双边自由贸易区对中国中西部的影响大于对中国东部的影响。     

The Effect of E-Business on Corporate Performance: Firm Level Evidence for Belgium

E-business offers buyers and sellers a new form of communication and provides an opportunity to create new marketplaces. In general it is suggested that the development of e-business results in higher firm productivity and efficiency as a result of lower search and transaction costs. However, there are a number of recent studies, which demonstrate that firms engaging in e-commerce need not perform better compared to more traditional enterprises. To date, there is little empirical evidence on the impact of information technology on corporate performance. This paper is the first that uses a large representative data set of Belgian firms to study empirically the impact of e-business on productivity and cost efficiency of firms. Our main conclusions can be summarised as follows: (1) The penetration of the Internet in Belgian firms is high; however, the use of e-business is still limited. (2) It is especially the large firms that engage in e-business and mostly in e-procurement. (3) E-business has no effect on total factor productivity in small firms; however, we find positive effects on performance of e-business in large firms.     

Do Exporting Firms Pay Higher Wages? Evidence from Kenya's Manufacturing Sector

Abstract: When trade liberalization was first embarked on in Kenya some 20 years ago, a key argument against it was that it would reduce domestic wages, as exporting firms sought to remain competitive versus, for example, the low‐cost Asian countries. A counter argument was that manufactured exports require more elaborate design, supervision, packaging and handling, and thus a more educated labor force than production for the domestic market. To attract such skills, exporting firms would need to pay higher wages than non‐exporting ones. This paper uses data from Kenyan manufacturing to study the impact of trade liberalization on earnings, distinguishing between exporting and non‐exporting firms. In particular, it investigates whether exporting firms paid a wage‐premium to their employees. The study uses manufacturing firm survey data from a World Bank regional project. The study has three important findings: (1) There was a large and significant effect of exporting on wages in the first decade of trade liberalization. During the first half of the 1990s, workers in exporting firms earned up to 30 percent more than those engaged in non‐exporting firms. The results are robust even after controlling for individual and firm‐level characteristics such as employee demographics, productivity, firm location and occupation. (2) After a decade of trade liberalization, exporting ceased to be a significant determinant of wages in Kenyan manufacturing, after controlling for productivity and firm location. (3) During the 2000s, casual or irregular employment became a more common feature of exporting firms. The results suggest that while higher wages were important in attracting skilled labor to exporting firms at the beginning of trade liberalization in the 1990s, domestic competition has since reduced the wage premium. Cost cutting pressures are instead reflected in the substitution of casual and low wage labor for permanent and better educated labor and in increased automation.     

Economic geography and inequality in China: Did improved market access widen spatial wage differences?

New economic geography (NEG) models predict that costly transport and the spatial distribution of demand affect the profits firms can earn in different locations, leading to higher wages for workers employed in cities with better geographic access to markets. In light of the ongoing economic integration and market reforms that occurred in China after 1995, we use three waves of Chinese Household Income Project (CHIP) data to measure the extent to which the influence of market access on wages changed and affected wage dispersion across Chinese cities over the next 12 years. Employing the gravity-based method of Redding and Venables (2004) to calculate the market access available to firms located in each city, we test whether the elasticity of the wage with respect to local market access increased over time. We find that in all three years market access of the worker's location has a positive and significant influence on the wage. Consistent with extensive labor market reforms of the late 1990s, the estimated wage elasticity doubles between 1995 and 2002 and is stable thereafter. Our estimates indicate that wages of all workers become more responsive to market forces in a manner consistent with NEG predictions, both skilled and unskilled and those working for state as well as private enterprises. We also provide evidence that these results are not driven by omission of other forms of agglomeration or by selection bias. Estimated spatial differences in nominal wages are large: a worker moving from an inland location to the coast in 2007 would have doubled his or her nominal wage. Counterfactual analysis indicates that spatial differences in market access contribute to wage inequality, but less so over time.
