中国短期融资券信用利差的实证研究

本文基于2007年4月至2009年8月的日数据,对中国五个主体信用级别短期融资券信用利差的决定因素进行了实证研究。实证结果表明各级别短期融资券信用利差与无风险利率指标负相关,与波动率指标正相关,从而验证了结构化模型在中国短期融资券市场的有效性。我们还发现国内短期融资券的信用利差与基于交易量的流动性指标总体上是正相关的。另外,实证模型解释力随信用级别的降低而单调上升,与欧美市场的实证结果是一致的。     

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.     

Exchange rate exposure and its determinants in China

This paper investigates the foreign exchange rate exposure and its determinants using the data of all firms listed on the Chinese stock market from 2005 to 2018. We find significantly linear and nonlinear exposures to bilateral as well as multilateral foreign exchange rates. Our temporal study also shows that considerably more Chinese firms were exposed to exchange rate fluctuations after the major exchange rate reform in 2015. We find a negligible role played by international operations of firms in explaining exposures. The level of exchange rate exposure is primarily explained by variables that are proxies for a firm's hedging costs. Larger firms, or firms with less leverage ratio, tend to have smaller exposures. Exposure is found to increase with a firm's growth opportunity. Last but not least, we find that leverage ratios and growth opportunities impact more significantly on exposures for firms with separation of control and cash flow rights.     

Does contracting institution affect the patterns of industrial specialization in China?

This study evaluates the importance of contracting institutions as a source of comparative advantage across Chinese provinces. We find that industries differ in their reliance on relationship-specific investments. Provinces with better contracting institutions specialize in industries with more intensive relationship-specific investments. We implement two proxies to measure contracting institutions, including efficiency of the legal system and service of contract enforcement. The empirical results of this study indicate that contracting institutions play a role in shaping the patterns of industrial specialization. Specifically, the service of contract enforcement has the first-order effect on the patterns of industrial specialization in China; by contrast, legal jurisdiction plays a modest role.     

What effect does the size of the state-owned sector have on regional growth in China?

This paper examines the effects state-owned enterprises (SOEs) have on China's economic growth. We present a simple and intuitive model of the political process, which predicts a larger state-owned sector will lead to lower growth rates. We then estimate regressions with various measures of and proxies for real output growth using a variety of other factors, including measures of the size of the state-owned sector, as regressors.We find a robust negative relation between the size of state-owned enterprises and the provincial growth rate. The estimates indicate that a decrease in the SOE share of industrial production by 10 percentage points increases real GDP growth the following year by between 0.7% and 1.2%. The average impact of a reduction in the SOE share in employment by 10 percentage points is between 1.6% and 2.3%.     

The Impact of Financial and Tax Reporting Incentives on Option Grants to Canadian CEOs*

This study explores the effects of financial and tax reporting incentives on options granted to chief executive officers in Canada. Extant studies with a similar objective (Yermack 1995; Matsunaga 1995) explore predominantly nonqualified U.S. option grants that are deductible to the extent that the options are in the money at the time of exercise. In contrast, Canadian firms do not get a tax deduction for their stock option grants at any time. In both countries, no expense is recorded for financial reporting purposes. As a result, the financial reporting and tax reporting trade‐off is more pronounced in the Canadian setting of this study compared with the U.S. setting. We measure option granting behavior as the ratio of the Black‐Scholes value of stock option grants to the sum of cash compensation and the value of stock option grants. Using a sample of 806 firm‐year observations during the period 1993‐95, we find that observed option grants are significantly correlated with proxies for short‐run financial reporting incentives. We also find evidence that option granting behavior is correlated with proxies for tax incentives.     

Does Accounting Conservatism Discipline Qualitative Disclosure? Evidence From Tone Management in the MD&A*

We investigate whether accounting conservatism, which has been found to be effective in constraining management opportunism in other settings, constrains upward tone management (UTM) in the Management's Discussion and Analysis (MD&A) portion of the 10-K filing. We hypothesize that conservatism makes it harder for managers to opportunistically downplay bad news and magnify good news when discussing current performance. Consistent with this hypothesis, we find that UTM is negatively associated with several accounting conservatism proxies. Additionally, we hypothesize and find that this association is stronger for firms where managers have higher incentives to manipulate tone. In supplemental analyses, we find evidence to suggest that our results are not due to an endogenous relationship between conservatism and UTM. We also find that conservatism neither encourages downward tone management (DTM) nor constrains managers from conveying real information about future good news. Together, our results suggest that accounting conservatism improves disclosure narratives.     

FinTech adoption and the effects of economic uncertainty on household consumption

This paper examines how the adoption of FinTech affects household consumption in the presence of economic uncertainty. We use regional-level FinTech adoption and economic uncertainty measurement, along with representative household-level consumption data, to investigate this issue. Our empirical analysis shows that while high levels of economic uncertainty lead to a shift in household consumption from services to non-durable goods, widespread adoption of FinTech overcomes this negative effect and prevents the reduction in service spending. We use the distance of a household from Hangzhou and the economic uncertainty in the United States as proxies for exogenous variation in FinTech adoption and economic uncertainty in China, respectively, and find similar results. Focusing on the transmission channel, we find that FinTech helps alleviate credit constraints, contributes to entrepreneurship and employment opportunities, and thus mitigates the negative impact of economic uncertainty on household consumption.     

Is R&D cash flow sensitive? Evidence from Chinese industrial firms

We hypothesize that research and development (R&D) is sensitive to cash flow fluctuations due to asymmetric information and agency problems in the credit market. We adopt a variant of the Q model for R&D investment using the value of the firm, physical capital and employment to capture firm fundamentals as proxies for investment opportunities. We add cash flow to this specification, and estimate the augmented model separately for R&D participation and spending decisions using data on Chinese industrial firms for the period 2001–2006. We find that R&D participation and spending are sensitive to cash flow fluctuations, conditional on firm fundamentals. We also find that the cash flow sensitivity of R&D varies across firms depending on ownership.     

Greed and grievance in civil war

We investigate the causes of civil war, using a new data setof wars during 1960–99. Rebellion may be explained byatypically severe grievances, such as high inequality, a lackof political rights, or ethnic and religious divisions in society.Alternatively, it might be explained by atypical opportunitiesfor building a rebel organization. While it is difficult tofind proxies for grievances and opportunities, we find thatpolitical and social variables that are most obviously relatedto grievances have little explanatory power. By contrast, economicvariables, which could proxy some grievances but are perhapsmore obviously related to the viability of rebellion, provideconsiderably more explanatory power.     

Social capital and Rotating Labor Associations in rural China

This paper studies social capital and households' participation in Rotating Labor Associations (ROLAs) in rural China. I employ both self-reported trust and the presence of village temple prior to 1949 as proxies for social capital. I find that households in communities with higher levels of social capital are more likely to participate in ROLAs, using household data collected from the Gansu province in China.     

Who Herds? Who Doesn't? Estimates of Analysts’ Herding Propensity in Forecasting Earnings

We develop parametric estimates of the imitation‐driven herding propensity of analysts and their earnings forecasts. By invoking rational expectations, we solve an explicit analyst optimization problem and estimate herding propensity using two measures: First, we estimate analysts’ posterior beliefs using actual earnings plus a realization drawn from a mean‐zero normal distribution. Second, we estimate herding propensity without seeding a random error, and allow for nonorthogonal information signals. In doing so, we avoid using the analyst's prior forecast as the proxy for his posterior beliefs, which is a traditional criticism in the literature. We find that more than 60 percent of analysts herd toward the prevailing consensus, and herding propensity is associated with various economic factors. We also validate our herding propensity measure by confirming its predictive power in explaining the cross‐sectional variation in analysts’ out‐of‐sample herding behavior and forecast accuracy. Finally, we find that forecasts adjusted for analysts’ herding propensity are less biased than the raw forecasts. This adjustment formula can help researchers and investors obtain better proxies for analysts’ unbiased earnings forecasts.     

An Integrated Corporate Governance Framework and Financial Performance in South African‐Listed Corporations

This paper investigates the relationship between an integrated corporate governance (CG) index and financial performance using a sample of 169 South African (SA)‐listed corporations between 2002 and 2007. We find a statistically significant and positive association between a broad set of good CG practices and financial performance. In a series of sensitivity analyses, we find that our results are robust to endogeneity, different financial performance proxies, alternative CG weighting scheme and firm‐level fixed effects. We further distinctively examine the link between complying with SA context‐specific stakeholder CG provisions and financial performance. In line with political cost and resource dependence theories, our results reveal a statistically significant and positive nexus between compliance with stakeholder CG provisions and financial performance.     

The relationship between liquidity and returns on the Chinese stock market

The goal of this paper is to examine the impact of liquidity on returns on the Shanghai stock exchange (SHSE) and the Shenzhen stock exchange (SZSE). We proxy liquidity with the trading volume (TV), the turnover rate (TR), and the trading probability (TP). Using daily data for the period January 1997 and December 2003, we find mixed results on the relationship between liquidity and returns. There is greater evidence of liquidity having a negative effect on returns on the SHSE than on the SZSE. However, this evidence is not robust across the three proxies for liquidity that we use.     

Qualitative Disclosure and Changes in Sell‐Side Financial Analysts' Information Environment

We examine a routine and timely disclosure, earnings press releases, to determine the extent to which several novel qualitative elements of such disclosures are associated with changes in sell‐side financial analysts' information environment. Using a comprehensive set of GARCH‐based (generalized autoregressive conditional heteroscedasticity) proxies, we examine how disclosure readability's components, across‐document textual similarity, and within‐document lexical diversity alter analysts' information environment. We find that readability in the form of shorter sentences, textual similarity, and lexical diversity are strongly related to decreases in analysts' uncertainty. Further, shorter sentences and lexical diversity improve both public and private information precision, whereas similarity affects solely analysts' private information precision. While the GARCH‐based proxies allow us to alleviate concerns regarding potentially spurious inferences (Sheng and Thevenot 2012), we note as a caveat that such an estimation restricts our inferences to large, stable, and heavily followed firms. These findings should be of interest to analysts who may wish to explore the latent information contained within the qualitative elements of disclosure, regulators who direct the form and content of disclosure, and academics who study the use (and possible misuse) of various forms of information and its presentation.     

Information Conveyed in Announcements of Analyst Coverage*

This paper examines the security market response to the announcement of sell-side analysts' decisions to initiate coverage of a firm. We examine the market reaction to the initiation announcement and the accompanying investment recommendation, by disaggregating our sample based on existing analyst coverage at the announcement date. We find, on average, a significantly larger, positive stock price reaction to buy recommendations conveyed in announcements of coverage initiation for firms with a small existing analyst following compared to such announcements for firms receiving no prior analyst coverage. Tests show that the relation between the extent of preexisting analyst coverage and market response is nonlinear and concave down in shape. Specifically we find that lightly followed firms, on average, experience larger price reactions to announcements of coverage initiations than either previously uncovered firms or more heavily followed firms. We test for and find that this result holds over a range of definitions of light coverage and is not attributable to the presence of an underwriting relationship existing between the analyst's employer and the firm receiving coverage. We do find that initiations by analysts named to Institutional Investor magazine's “All-American Research Team” produce a significantly larger market reaction than do initiations by non-All-American security analysts. In addition, similar to the market response associated with other types of information events, we observe that proxies for the richness of the initiated firms' preannouncement information environment are associated with event-day average abnormal returns.     

Contract Engagement in the Small-Scale Tuna-Fishing Economies of East Java

We examine the informal contractual relationships formed by artisanal fishers (AFs) and intermediaries in the small-scale tuna-fishing economies of East Java, Indonesia, using data from a survey of 436 boat captains. Our exploration of the factors motivating AFs to engage in such contracts uses instrumental-variable probit regressions to control for endogeneity in our transaction-cost economics model. This model incorporates the importance of household characteristics, transaction characteristics, transaction costs, risk behaviour, and trust in the choice of contract between AFs and their intermediaries. These intermediaries play an important role in facilitating transactions and contractual relationships between AFs and processors in the marketing value chain. We find that social capital is a statistically significant instrumental variable in our model. We also find that risk behaviour and trust are not statistically significant in influencing the choice of governance structure.     

Earnings Announcements and Information Asymmetry: An Intra‐Day Analysis*

This paper examines the effect of earnings announcements on information asymmetry as perceived by specialists. We use changes in quoted bid‐ask spreads and depths (relative to the average value in the non‐announcement period) as proxies for changes in information asymmetry in the market. To our knowledge, we are the first to employ a model that captures the simultaneous nature of the specialists' choice of spreads and depths in reaction to earnings news. We provide evidence that spreads are wider and depths are smaller before the release of earnings announcements. We also find that changes to depths are greater for announcements of quarterly earnings than for announcements of annual earnings and changes to spreads persist longer into the post‐announcement period when announcements are made outside trading hours. These changes to spreads and depths persist when earnings announcements are made after trading hours.     

Stock Price Reactions to the Repricing of Employee Stock Options*

We study whether the repricing of employee stock options is in the best interests of common shareholders by examining the excess stock returns associated with timely, noncontamin‐ated repricing announcements made by Canadian firms. On the basis of three theories of why firms reprice, we develop competing predictions about the mean announcement‐date excess stock return and the cross‐sectional relations among excess stock returns, the estimated probability of repricing, and proxies for predictions from each theory. For a sample of 72 noncontaminated repricing announcements made by Canadian firms between November 1994 and July 2001, we find a reliably positive three‐day announcement‐date mean excess return of 4.9 percent. The results of our cross‐sectional analyses suggest that the market responds favorably to repricings because they assist in retaining key employees even though, at the margin, they enable managers to extract rents from shareholders. We do not find sufficient statistically significant evidence to reliably conclude that repricings are done to realign employee incentives.     

Has Greater Competition Restrained U.S. Inflation?

This paper shows how increased goods market competition affects the behavior of inflation in a multisector economy. By raising the price elasticity of demand, increased goods market competition theoretically lowers inflation and makes the aggregate price level less sensitive to aggregate demand shocks. We find that proxies for the aggregate degree of goods market competition are statistically and economically significant in short-run Phillips curve models of core inflation. Evidence indicates that heightened goods market competition has flattened the slope of the short-run, expectations-augmented Phillips curve and slightly lowered the nonaccelerating inflation rate of unemployment (NAIRU).
