Zombie Firms and Debt Accumulation: A Theoretical Framework and Chinese Experience

In recent years, as China has grappled with rising debt and broad economic restructure, the prevalence of zombie firms has become a critical problem. This paper provides a theoretical framework illustrating the rationale behind the occurrence of zombie firms from the perspective of banks. We develop differential equations to model a bank's expectation and the ex ante estimate that underlies its decision to refinance an insolvent borrower. An optimistic expectation is essential in zombie lending and is intrinsic to the countercyclical pattern of zombie firms. Our model also predicts that debt can build up to an unsustainable level if recovery of profitability is sluggish or the initial debt burden is too high. Examining the Chinese experience of zombie firms over 2007–2017, this paper highlights two findings. First, the share of zombie firms among Shanghai and Shenzhen A‐share listed companies demonstrates a countercyclical pattern. Second, the positive correlation between zombie share and debt accumulation across manufacturing sectors sheds light on the link between zombie firms and the rising corporate debt in China. To deal with the “zombie” problem, the government should carefully weigh its policies to avoid further distortions because the occurrence of zombie firms may be inevitable and impossible to eliminate.     

Unfinished business: Zombie firms among SME in Japan’s lost decades

The “soft budget problem,” by which banks loosen their lending stances toward long-term client firms despite worsening business conditions, has been widely discussed in the field of financial studies. In Japan, this problem has attracted attention particularly in connection to so-called “zombie firms,” financially weak firms sustained by discounted interest rates and evergreen lending which have become a major research and political interest in recent years. In this article, we focus on zombie firms among small and medium-sized enterprises (SME), a corporate category that has hitherto received less consideration in the discussion about Japan’s zombie firms. We find that: (1) many zombie firms exist among SME and that the zombie firm ratio increases as firm size decreases; and (2) some zombie firms eventually emerge from zombie status among SME. In other words, zombie firms are likely problematic from the view of the efficiency of the industries to which they belong. But when one considers that many zombie firms achieve revival, it would seem inappropriate to uniformly promote their elimination. Since ending zombie status seems to directly imply market exit for many SME, it is important to conduct preliminary screening to prevent the creation of zombie firms in the first place.     

A 50-year history of “zombie firms” in Japan: How banks and shareholders have been involved in corporate bailouts?

We review long-term changes in “zombie firms” in Japan over this half-century using listed firm data with a framework in which the concept of “zombie firms” includes possible efficient bailouts. The first wave of zombie firms occurred during the period of main banks (hereinafter MBs). MBs were able to actively choose which firms would receive bailouts at the time. However, commonly held beliefs about MBs’ monitoring power and the special role of corporate groups and long-term credit banks for bailouts are not supported. In the largest wave of the lost decade, we find the zombie firm problem in the manufacturing sector was just as serious as the non-manufacturing in terms of firm count. Moreover, the pathological phenomena such as unwilling concentration of loans to MBs were also rather typical in the manufacturing. Soft budget constraints have continued in the manufacturing even after the resolution of banks’ non-performing loans since the bubble burst came to an end, leading to the manufacturing-centered third wave of zombie firms following the Global Financial Crisis.     

Fiscal stress and the formation of zombie firms: Evidence from China

We investigate the causality between government fiscal stress and the formation of zombie firms. We use the province-managing-county reform recently initiated in China to exogenously identify the change in financial pressures of local governments. Matching industrial firm data and county economic data from 1999 to 2013, we carry out difference-in-differences estimation and find that the possibility of zombie firms' formation significantly decreases after the reform. Specifically, the suppression effect is more pronounced in counties with low level of initial economic development, more debt stocks, poor financial situations, and high employment pressures. Further, the mechanism analysis shows that the reform improves firms' performance, such as productivity and profitability, through the decline of tax burden, which inhibits the formation of zombie firms. Our study contributes to a profound understanding of the causes of zombie firms in a large transition economy.     

Zombie firms and over-capacity in Chinese manufacturing

The problems of over-capacity and zombie firms in China's manufacturing attract all aspects of attention, but academic analysis is still absent. Using firm-level data of Chinese manufacturing, this study first documents the problems of over-capacity and zombie firms during 2011–2013. We find that the over-capacity problem is much more severe in the northeastern and western regions of China, in heavy chemical industries, and in state-owned sector. The distribution of zombie firms is in a similar manner across region, industry and ownership. We also empirically test the relationship between zombie firms and over-capacity, finding that zombie firms cause and worsen over-capacity by crowding out healthy firms.     

Can Trade Facilitation Prevent the Formation of Zombie Firms? Evidence from the China Railway Express

Using data on firms listed on Chinese A‐share markets from 2009 to 2017, this paper applies the difference‐in‐difference model to test the effect of trade facilitation on preventing the formation of zombie firms. We find that the China Railway Express (CRE) significantly prevented the formation of such firms. Mechanism tests show: (i) the CRE has accelerated the speed of sales, which increased the overseas sales revenue of firms; (ii) the economies of scale and the capital accumulation effect caused by the CRE can help increase firms’ solvency and development ability. Heterogeneity analysis indicates that the effect of the CRE on preventing the formation of zombie firms is mainly reflected in non‐state‐owned firms, firms in highly competitive industries, and firms in the eastern region of China. We suggest that China should continue to promote trade facilitation by expanding the CRE and strengthening the market's dominant role in preventing the formation of zombie firms. Disadvantaged firms should seize the development opportunities brought by the CRE.     

China's Overinvestment and International Trade Conflicts

For a long time, China's impressive growth performance has been driven by investment and high productivity gains. Based on a discussion of possible overcapacities and overinvestment in China, this paper investigates the sustainability of China's investment and export‐driven growth model. Since the turn of the millennium, buoyant capital inflows and low interest rates have been at the root of overinvestment and misallocation of capital, which necessitated export subsidies to clear markets. The overinvestment boom is argued to have ended around 2014. Since then, the overcapacities have weakened China's bargaining position in the US–Chinese trade conflict and have tempted Chinese authorities to postpone the restructuring of the Chinese economy by providing low‐interest credit. The gradual reemergence of quasi‐soft budget constraints is seen to undermine China's long‐term growth potential.     

Employment burden, government ownership and soft budget constraints: Evidence from a Chinese enterprise survey

This paper investigates two competing theories of soft budget constraint (SBC), namely the ownership hypothesis and the policy burden hypothesis. While the ownership hypothesis attributes the SBC problem to government ownership, the policy burden hypothesis predicts that privatization would not eliminate the SBC problem, as long as the major policy burden – maintaining employment – is not removed from enterprises. Using a panel dataset from a survey of Chinese enterprises, I conduct empirical tests on these two competing hypotheses. I explicitly address endogeneity and data-censoring problems by using instruments and estimating a two-step tobit model. The test results support the policy burden hypothesis but not the ownership hypothesis. My finding emphasizes the importance of creating a sound social security system in the process of China's enterprise reform.     

Policy certainty and heterogeneous firm innovation: Evidence from China

This paper investigates how policy certainty affects firm innovation activities. The identification hinges on the overlap of the elite dualism system in China. Naturally, a city Party leader served as the prior mayor in the same city is more likely to carry out the policy decisions made by the previous local administration, since he/she is one of the crucial leaders to make these decisions. In this circumstance, the policy certainty level would be higher for local listed firms. We find that the patent filings of listed firms, who enjoy a more stable local policy environment, significantly and substantially increase into the future. Such positive effects are robust to different model specifications and subsample analyses. Moreover, this paper documents the role of heterogeneity in the effects of policy certainty on firm innovation. The increased patent filings caused by a higher level of local policy certainty are mostly driven by state-owned enterprises (SOEs) and firms having lower financial constraints. We further show that a higher level of local policy certainty would increase the stability of government subsidies received by firms, so the listed firms can more aggressively engage in innovation activities.     

For goodwill or resources? The rationale behind firms' corporate philanthropy in an environment with high economic policy uncertainty

This paper investigates the impact of economic policy uncertainty (EPU) on the corporate philanthropy (CP) behaviors of firms using a dataset from Chinese A-share listed firms. We find that, on average, firms decrease their CP significantly when economic policy uncertainty increases, but the response is heterogeneous for firms with different ownership types. Compared with their counterparts, private firms are willing to contribute more donations in an environment with high economic policy uncertainty. Further analysis shows that private firms take on more other types of corporate social responsibility at the same time, and private firms' additional CP in a high EPU environment is rewarded with more subsidies, indicating that altruistic and political motives may play important roles in driving the CP behaviors of private firms. There is no evidence that private firms selling products directly to consumers are more likely to engage in additional CP. Our findings indicate that the main motivation behind Chinese private firms' additional CP under high economic policy uncertainty is seeking more government resources, instead of keeping consumers loyal by maintaining good reputations during hard periods.     

R&D subsidies and business R&D: Evidence from high-tech manufacturing firms in Jiangsu

We investigate how R&D subsidies affect business R&D investments using cross-section data of high-tech manufacturing firms in Jiangsu province of China. Our estimations based on propensity score matching suggest that public subsidies positively influence business R&D investments. Further classifying firms into different groups by size, financial constraints, and ownership, we find that the stimulation effect is more significant and stronger for smaller firms, more financially constrained firms, and private-owned firms. The heterogeneity of policy effects with respect to export status, Relative Comparative Advantage index, region, and industry are also discussed.     

Export subsidies and trade policy: The experience of Kenya

This paper finds that manufacturing firms in Kenya have responded poorly to the availability of export subsidies. It is argued that this has resulted from the delays and uncertainty surrounding disbursement procedures, and from the limited extent to which the subsidy lessened the anti-export bias of a policy structure which has emphasized import substitution. It is further argued that a budgetary constraint makes it impossible to offset the anti-export bias with export subsidies at existing levels of domestic market protection, and that what is required is the lowering and standardization of domestic market protection levels, which can be most appropriately achieved through a combination of devaluation and trade tax/subsidy changes.     

A panel study of zombie SMEs in Japan: Identification,borrowing and investment behavior

Utilizing a panel dataset of firms for the period 1999–2008, we estimated the prevalence of zombies among Japanese Small- and Medium-sized enterprises (SMEs) and their borrowing and investment behaviors. We observe that 4–13% of SMEs were zombie firms during the period 1999–2008. The estimation of the borrowing function reveals that SME zombie firms did not change their loans in response to a change in land values due to evergreening. We also observe that the profitability of investment, measured by marginal q, did not have positive effects on investments of zombie firms. This indicates that investment increase resulting from evergreen loans was not necessarily productive or profitable.     

Determinants and effects of the use of COVID-19 business support programs in Japan

Using a survey of and financial data for Japanese small- and medium-enterprises (SMEs), this paper examines the determinants of firms’ use of the business support programs provided by the Japanese government during the COVID-19 pandemic and their effect. With respect to the determinants, we obtain the following three findings: First, firms were more likely to have obtained subsidized loans, grants, or subsidies the more their sales had fallen during the pandemic, suggesting that funds flowed to firms that were adversely affected by the pandemic. Second, the likelihood that firms obtained funds was higher if their credit scores were lower or if they were classified as “zombies” and/or “low-return borrowers” before the pandemic, suggesting that the government programs also helped firms that had been under-performing before the pandemic. Third, firms were more likely to receive funds if they had a stronger relationship with their main bank before, suggesting that bank relationships play an important role in firms’ access to government programs. Regarding the causal effects, we obtain the following three findings: First, except for the subsidies for employment adjustment, the support programs increased the cash holdings of user firms. Second, subsidized loans from private financial institutions lowered exit rates, while none of the programs had a significantly positive effect on employment relative to non-users (or in absolute terms). Third, the credit scores and profit-to-sales ratio of firms that used the support programs decreased and the likelihood of such firms being a zombie and/or a low-return borrower increased. Overall, our findings provide a cautionary tale in that the business support programs produced mixed results in that they may have prevented business failures but have also helped to prop up firms that are not viable in the long run.

Human capital theory and UK vocational training policy

Since the Industrial Training Act of 1964, the UK governmenthas adopted a variety of policies intended to redress a problemof under-investment in vocational training. In the 1960s and1970s it attempted to regulate the training provided by firms,through a levy scheme. More recently, subsidised training schemeshave been the centrepiece of policy. This paper examines theexplanations for market failure in vocational training, andexplores the rationale for such policies. Under-investment canarise from credit constraints and uncertainty facing trainees,and from imperfect competition in the labour market which createsexternal benefits for firms. Both subsidies and regulation canbe effective in dealing with these problems, although it isargued that the training levy scheme, as implemented in theUK and other countries, should be viewed mainly as a mechanismfor releasing credit constraints.     

‘Doing-good’ and ‘doing-well’ in Chinese publicly listed firms

Recently, the presumed benefits of corporate social responsibility have become an important issue, especially for China where institutional settings are quite different from other parts of the world. Using an internationally accepted benchmark (OECD's Principles of Corporate Governance, OECD, 2004), this study constructs a corporate social responsibility (CSR) index to measure the quality of the corporate social responsibility practices of the 100 major Chinese listed firms during 2004–2007. This enables us to evaluate the progress of the corporate social responsibility practices of Chinese firms. The results show that Chinese companies have been making progress in their corporate social responsibility practices. The findings also show that market rewards Chinese firms for improving their corporate governance practices which implies ‘doing-good’ leads to ‘doing-well’ in the equity market in China. We also find that overseas-listed and more profitable Chinese firms have better improvement in CSR practice. This study has policy implications in pushing for further CSR initiatives in other emerging markets.

Cross-border mergers with flexible policy regime: The role of efficiency and market size

This study provides a theoretical and empirical framework for understanding the determinants of cross-border mergers. Past literature has focused on the effect of trade liberalization as the key factor triggering international mergers. We introduce the idea of flexible policy regime in which optimal policies are sensitive to whether a cross-border acquisition has taken place or not. In a free-trade model given asymmetries in marginal cost, we find that optimal subsidies decline when firms acquire inefficient foreign firms while optimal subsidies increase when firms acquire efficient firms. We also find that as the efficiency of the acquirer increases, the profitability of the acquisition and hence the likelihood that it takes place also increases. We find that the role of market size in triggering cross-border acquisitions may be limited even with free trade.     

Regional policy in a multiregional setting: when the poorest are hurt by subsidies

Regional policies that seek to reduce economic inequalities between regions are common. These policies normally involve subsidies or transfers to the poorest regions. Over any given short-term horizon such subsidies serve to reduce inter-regional inequalities, but as they also affect migration patterns the long-term effects are less clear. This paper demonstrates using a three-region general equilibrium model that subsidising the poorest region may be to the detriment of the periphery as a whole and even to the very region that receives the subsidy, if the subsidy draws firms away from a nearby region that would function better as a production centre. If the subsidy does not attract a sufficient number of firms to the subsidised region, then the long-term effect on the residents of that region would be negative. Though further research is needed to isolate the conditions under which such an effect would arise, this result has potentially important implications for the design of regional policy.
