  • 详情 Earnings Management as an Unintended Consequence of IPO Pricing Regulation: Causal Evidence from China
    Although it is common for companies to manage their accounting profits upward before going public in capital markets worldwide, existing literature documents that pre-listing earnings management is most prevalent in China. This has exacerbated the information asymmetry between IPO companies and external investors, and has become a bottleneck restricting China from improving investor protection. This paper posits that pre-listing earnings management is an unintended consequence of China's compromised IPO pricing mechanism, as the China Securities Regulatory Commission imposed a 23x P/E cap on IPOs in June 2014, following a failed market-oriented reform between 2009 and 2012. Since the pricing cap forced the companies to issue new shares at below-fair-market prices, they were motivated to inflate earnings per share to recover the losses. Using mainland Chinese companies listed on the Hong Kong stock market as the control group, we provide causal evidence for our proposition in a cohort DID model. We further find that such opportunistic accounting practice is concentrated among privately controlled IPO companies with high potential valuation. The pricing cap has also led to adverse capital market consequences as it significantly increases the probability of financial performance reversals and stock price crashes after companies go public, and also largely reduces investors' long-term returns. These findings suggest that the Chinese government's paternalistic investor protection has not achieved the desired results, and IPO pricing should be deregulated.
  • 详情 Family Planning Confronts Delayed Retirement in China: The Retirement Intention of Only-Child Parents
    By establishing a labor-retirement model within China’s unique intergenerational support culture and one-child policy, this study provides evidence of the one-child policy’s early effect on individuals’ retirement decisions. This finding highlights a contradiction between the retirement intentions of the 1960s and 1970s generations, who are most affected by the one-child policy, and the delayed retirement policy of Chinese government. Utilizing data from the CHARLS 2011-2018 and employing OLS, IV, and fuzzy cohort DID estimation methods, we observe that only-child parents tend to retire at an earlier age compared to non-only-child parents. This early effect of the one-child policy on retirement decisions can be attributed to intergenerational support for children’s marriage and career, as well as the educational attainments of children, as confirmed by both theoretical and empirical analysis.
  • 详情 The Green Benefits of Stock Market Liberalization: Evidence from China
    Taking the Stock Connect scheme as an exogenous shock based on data of China’s Ashare non-financial listed companies from 2009 to 2021, we identify the causal effect of stock market liberalization on green innovation. The baseline result based on a staggered difference-indifferences (DID) model suggests that stock market liberalization promotes corporate green innovation and this effect is similar to the green benefits of China’s mandatory environmental regulations. The results are robust to various checks, including the parallel trend tests, placebo tests, and the heterogenous time-varying treatment test based on Bacon decomposition and the DIDM approach. The enhanced continuity of corporate financing, improved corporate green governance and increased firm external technological collaboration are three plausible channels that allow stock market liberalization to promote corporate green innovation. Moreover, the effect is more significant for clean firms, non-SOEs, and firms in a good institutional environment. Further analysis suggests that the green innovation-enhancing effects of stock market liberalization are more likely to be high-quality innovation. Our paper provides new insights into understanding the green benefits of stock market liberalization and achieving sustainable economic development in developing countries.
  • 详情 Can social credit system construction improve enterprise innovation? Evidence from China
    The progression of the social credit system is crucial for fostering enterprise innovation and elevating the quality of economic development. Based on the quasi-natural experiment of establishing demonstration cities for the social credit system, this study delves into whether the construction of a social credit system can indeed foster enterprise innovation. Our findings indicate that the establishment of demonstration cities for social credit system promotes enterprise innovation and improves the quality of innovation. Furthermore, mechanism test shows that it alleviates financing constraints faced by enterprises, leading to an increase in the scale and maturity of corporate loans, ultimately fostering corporate innovation. Further analysis of heterogeneity highlights that this positive impact is particularly evident in non-state-owned enterprises and those facing severe financing constraints. These findings present insights that the pivotal role of informal institutions, such as the social credit system, in facilitating the upgrading of industrial structures and augmenting the quality of economic development.
  • 详情 Agglomeration and Innovation: Evidence from Skyscraper Development in China
    The effects of skyscraper development on surrounding firms’ innovation in China is assessed in this paper, and empirical results show that skyscraper development significantly promotes the innovation of firms within 1 km of skyscrapers. However, such effect only exists around very tall skyscrapers in large cities. This means that skyscraper development in small cities often is unfit for the economic fundamentals of these cities, which may weaken the positive externalities generated by skyscrapers. The mechanism analysis in this paper shows that increased surrounding population density brought by skyscraper development and knowledge sharing between firms surrounding the skyscrapers and other firms in the same city are the main paths through which skyscrapers affect innovation.
  • 详情 The Performance of Hedge Fund Industry during the Covid-19 Crisis – Theoretical Characteristics and Empirical Aspects
    The study reveals that the COVID-19 crisis has had a strong but one-off negative impact on the hedge fund industry. It also shows that during the new coronavirus pandemic, the main components of the hedge fund industry achieved only partially their main investment goal, i.e. they as a whole provided a hedge of the investment risk but did not produce higher than the market return in the conditions of a growing capital market. In this situation, due to the relatively stable М&A market, the Event-Driven Risk Arbitrage strategy was undoubtedly most successful, followed by the Emerging Markets, the Global Macro and the Long/Short Equity strategies. The worst performance was reported for the Fixed Income Arbitrage strategy due to the currently overvalued bond markets and to the expectations for higher inflation rates in the countries with developed capital markets.
  • 详情 The Role of Governmental Venture Capital in Value Creation for Investee Firms: Evidence from Chinese Government Guidance Funds
    We study the role of Chinese government guidance funds (GGFs) in value creation for investee firms. Using a sample of 2,855 firms that went public during the period of 2010-2021, we show that GGF-backed IPO firms had higher initial returns than non-VC-backed IPO firms and nonGGF VC-backed IPO firms. After decomposing the initial return into IPO underpricing and market overvaluation, we find that GGF-backed firms enjoyed higher overvaluation and lower underpricing than other firms. Consistent with investor sentiment and information asymmetry hypothesis, our results indicate that public investors value the benefits of political resources more than the costs of government interference associated with GGF sponsoring. However, GGF-backed firms did not outperform other-VC-backed firms when post-IPO long-term stock, operating and innovation performance is assessed. The divergence in the effects of GGFs observed in the financial and product markets reveals the complexity in evaluating the role of GGFs in value creation.
  • 详情 Value of Qualification to Buy a House: Evidence from the Housing Purchase Restriction Policy in China
    China’s housing purchase restriction (HPR) policy imposes administrative restrictions on households’ home purchase eligibility to curb speculative demand. We quantify households’ willingness to pay (WTP) to re-acquire such eligibility. The empirical results based on the staggered DID specification suggest that when local governments implement the HPR policy, the transaction prices of judicial housing auctions legally exempted from HPR increase by 18.91%. This HPR-exempted qualification premium can be converted to an estimate of 22.48% of the transaction price as buyers’ WTP for home purchase eligibility. The heterogeneity analysis also suggests that the WTP significantly increases when speculative incentives are stronger in the housing market. If policymakers in mainland China consider replacing the HPR policy with an additional buyer transaction tax like that in Singapore and Hong Kong, China, the WTP estimates can serve as the benchmark in setting the tax rate.
  • 详情 碳风险、区域低碳转型与银团贷款定价
    《巴黎气候协定》以及碳达峰、碳中和目标要求中国向低碳经济发展模式转型。本文以《巴黎气候协定》签署为事件冲击,采用连续型 DID 模型探究了区域低碳转型风险对银团贷款定价的影响。研究发现,自协定签署后,中国高碳排放地区的银团贷款存在显著为正的碳风险溢价;由于地区碳风险导致贷款违约风险上升,从而提高了企业贷款成本。此外,研究还发现:碳风险溢价的高低受地区自然环境和制度环境特征的影响;在法制化程度高的地区,银行因承担污染连带责任而提高对碳风险的重视程度,相应地提高了碳风险溢价;在产品市场发育程度高的地区,价格机制和竞争机制能够激励低碳产品生产和低碳技术研发,从而降低碳风险溢价;在发生气候灾害的地区,银行执行国家救济职能,会降低碳风险溢价;在森林覆盖率高的地区,碳中和更易实现,林业碳汇收益和碳汇抵押资产能够增加现金流并降低信用风险,从而降低碳风险溢价。本文研究对于推动中国区域低碳转型和降低企业融资成本具有重要的政策启示意义。
  • 详情 Credit Card and Retail Deposit Competition: Evidence from the Debit Card Cut Campaign
    I show that issuing credit cards helps the bank compete for retail deposits in China. When credit card growth increases by 1%, retail deposit growth is expected to rise by 0.2% with regard to peers next year. This effect is stronger for small joint-stock banks compared with big state-owned banks. This is realized by introducing new credit card holders to visit the branch and open a savings account. DID test shows that after a shock that tightened new account opening, banks with higher credit card growth experienced a harsher decline in retail deposit growth. This paper highlights the customer introducing benefit of credit card promotion, which can provide an alternative explanation for the intensified competition in the credit card market in China. It also unveils the strategy that small banks can use to compete for the deposits of big state-owned banks, who intrinsically has more branches and retail customers.
