Corporate philanthropy in a politically uncertain environment: does it bring tangible benefits to a firm? Evidence from China

We examine the impact of political uncertainty on a firm’s corporate philanthropy (CP) contribution and the associated direct tangible benefits of CP to a firm. Specifically, we examine two testable hypotheses. (1) When facing political uncertainty, a firm makes more CP, and (2) after a firm makes CP contributions during a period of uncertainty, it will obtain future tangible benefits. Using a sample of Chinese listed firms, we document that a firm, on average, increases its CP significantly during a period of political uncertainty (e.g. when there is a new local communist party secretary or mayor). In addition, we report that, on average, a firm’s donation in year t is positively correlated with its amount of government subsidies, corporate income tax reduction, and short- and long-term bank loan amounts in year t?+?1. The findings are robust compared to those of placebo tests and fixed effect models, as well as when using an alternative measure of political uncertainty. We observe that the results are more pronounced among non-state-owned enterprises (non-SOEs) than those among SOEs, corroborating the notion that during a period of political uncertainty, non-SOEs are more willing to build political connections with new city leaders through CP than are SOEs.     

Analyst Optimism and Incentives under Market Uncertainty

We examine how analysts’ changing incentives driven by changes in market uncertainty affect their forecast optimism. Analysts issue more optimistically biased earnings forecasts and buy recommendations under high market uncertainty (VIX). The lower reputational costs and larger benefits of optimistic output explain the increased optimistic output: Analysts are less likely to be penalized for inaccuracy and can stimulate more trading activity from optimistically biased output when market uncertainty is high. We find that the likelihood of analysts’ turnover decreases, while the trading volume associated with optimistic output increases, with VIX. No evidence suggests that analysts’ self‐selection affects our findings on optimism and market uncertainty.     

Science vs. fear: the Ebola quarantine debate as a case study that reveals how the public perceives risk

This study focuses on newspaper coverage of the Hickox quarantine incident, using it as a case study to examine how the media characterized the spread of disease in an ongoing crisis situation characterized by uncertainty. The study builds on Slovic et al.’s research, who argue that risk perception is comprised of both emotional and analytical aspects. We employed a qualitative approach, first examining articles on Hickox’s story in The New York Times and New York Daily News between October 25 and 31, 2014; and second, readers’ comments in response to these articles. The findings from the newspaper articles show that in their treatment of the quarantine debate, the media did not address the issue of uncertainty, and thus continued the health authorities’ neglect of this issue. Although the media gave expression to various sides of the debate, it emphasized those who objected to the quarantine policy, thus raising the claim that the conflict was between ‘science’ and the public’s ‘irrational fears,’ and that the governors decided on quarantine in response to the public’s panic and fears. From our analysis of readers’ comments, it appears that these claims are unjustified. First, we found that the public did not speak in a single unified voice, but rather, was divided into supporters and opponents of quarantine. Both sides used scientific arguments and resorted to similar terminology, and tended to cite and present studies backing their arguments. As for irrational fears, although quarantine supporters expressed emotions, they indicated mainly concerns, not panic or hysteria.     

Understanding Investor Sentiment: The Case of Soccer

We examine the extent to which the stock market's inefficient responses to resolutions of uncertainty depend on investors’ biased ex ante beliefs regarding the probability distribution of future event outcomes or their ex post irrational reactions to these outcomes. We use a sample of publicly traded European soccer clubs and analyze their returns around important matches. Using a novel proxy for investors’ expectations based on contracts traded on betting exchanges (prediction markets), we find that within our sample, investor sentiment is attributable, in part, to a systematic bias in investors’ ex ante expectations. Investors are overly optimistic about their teams’ prospects ex ante and, on average, end up disappointed ex post, leading to negative postgame abnormal returns. Our evidence may have important implications for firms’ investment decisions and corporate control transactions.     

Types of investor uncertainty and the cost of equity capital

We jointly test the effects of two types of investor uncertainty, one related to future firm performance and unrelated to accruals (cash flow uncertainty) and one directly related to accrual estimation errors (accounting quality uncertainty). Distinct from prior studies, our uncertainty estimates are based on a matched‐firm design that minimizes the mechanical relationship between the two uncertainty variables. We find a strong negative relationship between cash flow uncertainty and multiple estimates of the cost of equity capital. With respect to accounting quality uncertainty, we find a strong positive association with both expected stock returns and implied costs of equity, but only in settings that control for cash flow uncertainty. Collectively, our results suggest the need to consider different types of investor uncertainty when examining how investor uncertainty affects the cost of equity capital.     

Facial Structure and Achievement Drive: Evidence from Financial Analysts

We use a large pictorial sample of Chinese financial analysts to test the association between facial width‐to‐height ratio (fWHR) and performance in men. Financial analysts offer an ideal setting for our investigation because we can objectively track individual analysts’ behaviors and performance. We find that high‐fWHR analysts are more likely to conduct corporate site visits and they exhibit better performance. The positive fWHR–performance association survives a battery of robustness checks and the association is more pronounced for analysts with lower status, for firms with higher uncertainty, and for analysts facing more intense competition. Our results suggest that the dominant trait predicted by fWHR is achievement drive.     

Information Uncertainty and Momentum Phenomenon Amidst Market Swings: Evidence From the Chinese Class A Share Market

This paper empirically investigates how firm-level information uncertainty impacts momentum profits in the Chinese Class A share market. We employ seven different factors to gauge the degree of firm-level information uncertainty—firm size, firm age, analysts’ coverage, return volatility, dispersion in analysts’ earnings forecast, trading volume, and the quality/strength of corporate governance (free float ratio). We find evidence showing that information uncertainty has an amplifying effect over the momentum profits, and the amplifying effect is more pronounced over the time periods following DOWN market state over the sample period from January 1996 to December 2013. The robustness of the empirical evidence is warranted by a risk-adjustment test based on the FF3F model and Wang and Xu’s (Financ Anal J 60(6):65–77, 2004) FF3F model, a sub-period analysis, and a different definition of market states. The empirical findings can provide an important reference point for international and domestic investors when adjusting investment strategies and portfolio positions in relatively volatile financial markets such as the Chinese stock market.     

Inconsistent Signals,Earnings Announcements,and Market Uncertainty

We test the proposition in Johnstone (2016) that new information may lead to higher, rather than lower, uncertainty about firms’ future payoffs. Based on the Bayesian rule, we hypothesize earnings news that is inconsistent with investors’ prior belief will lead to higher market uncertainty. Using earnings signals in the past few quarters to proxy for investors’ prior belief, we find supporting evidence that, relative to consistent earnings news, inconsistent news results in an increase in market uncertainty measured by implied volatility. Inconsistent earnings news has a larger effect on market uncertainty when prior beliefs are stronger and when the news is negative. Overall, our evidence highlights the importance of prior belief and inconsistent signals in understanding the effect of earnings news on market uncertainty.     

Pigou in the 21st Century: a tribute on the occasion of the 100th anniversary of the publication of The Economics of Welfare

The year 2020 marks the centennial of the publication of Arthur Cecil Pigou’s magnum opus The Economics of Welfare. Pigou’s pricing principles have had an enduring influence on the academic debate, with a widespread consensus having emerged among economists that Pigouvian taxes or subsidies are theoretically desirable, but politically infeasible. In this article, we revisit Pigou’s contribution and argue that this consensus is somewhat spurious, particularly in two ways: (1) Economists are too quick to ignore the theoretical problems and subtleties that Pigouvian pricing still faces; (2) The wholesale skepticism concerning the political viability of Pigouvian pricing is at odds with its recent practical achievements. These two points are made by, first, outlining the theoretical and political challenges that include uncertainty about the social cost of carbon, the unclear relationship between the cost–benefit and cost-effectiveness approaches, distributional concerns, fragmented ministerial responsibilities, an unstable tax base, commitment problems, lack of acceptance and trust between government and citizens as well as incomplete international cooperation. Secondly, we discuss the recent political success of Pigouvian pricing, as evidenced by the German government’s 2019 climate policy reform and the EU’s Green Deal. We conclude by presenting a research agenda for addressing the remaining barriers that need to be overcome to make Pigouvian pricing a common political practice.

     

Consumption and Hedging in Oil‐Importing Developing Countries

We study the consumption and hedging strategy of an oil‐importing developing country that faces multiple crude oil shocks. In our model, developing countries have two particular characteristics: their economies are mainly driven by natural resources and their technologies are less efficient in energy usage. The natural resource exports can be correlated with the crude oil shocks. The country can hedge against the crude oil uncertainty by taking long/short positions in existing crude oil futures contracts. We find that both inefficiencies in energy usage and shocks to the crude oil price lower the productivity of capital. This generates a negative income effect and a positive substitution effect, because today’s consumption is relatively cheaper than tomorrow’s consumption. Optimal consumption of the country depends on the magnitudes of these effects and on its risk‐aversion degree. Shocks to other crude oil factors, such as the convenience yield, are also studied. We find that the persistence of the shocks magnifies the income and substitution effects on consumption, thus also affecting the hedging strategy of the country. The demand for futures contracts is decomposed in a myopic demand, a pure hedging term and productive hedging demands. These hedging demands arise to hedge against changes in the productivity of capital due to changes in crude oil spot prices. We calibrate the model for Chile and study to what extent the country’s copper exports can be used to hedge the crude oil risk.     

Peer effects in corporate advertisement expenditure: Evidence from China

This study investigates whether industry peers affect focal firms’ advertising expenditure decisions and further explores the mechanisms and economic consequences of such effects. We find that peer firms have a significantly positive influence on the focal firm’s advertising expenditure. The results hold after a series of robustness tests. Additionally, the peer effects in advertising expenditure are more salient in industries with intense competition; and when economic policy uncertainty and demand uncertainty is higher. Interestingly, our results show that followers mimic the advertising expenditure of industry leaders, while leaders also react to followers’ advertising expenditure. We also find that the peer effects in advertising expenditure improve firms’ sales and market value. Our study contributes to a better understanding of peer effects on corporate decisions.     

Specialization and matching in professional services firms

Economic theory indicates that firms can match workers to jobs and promote productivity‐enhancing specialization better than markets, yet few data exist. We empirically test whether firms enhance matching and specialization in the context of obstetrics. We then examine whether consumers benefit from this. We find that high‐risk patients in group practices match with specialists more than patients of solo physicians, and this improves patients’ health outcomes. Matching based on a patient’s clinical need for a cesarean section delivery and a physician’s cesarean section skill also occurs, but less extensively. These results support the hypothesis that firms facilitate matching and specialization.     

Welfare effects of information and rationality in portfolio decisions under parameter uncertainty

We analyse and quantify, in a financial market with parameter uncertainty and for a Constant Relative Risk Aversion investor, the utility effects of two different boundedly rational (i.e. sub-optimal) investment strategies (namely, myopic and unconditional strategies) and compare them with each other and with the utility effect of full information. We show that effects are mainly caused by full information and predictability, being the effect of learning marginal. We also investigate the saver's decision regarding whether to manage her/his portfolio personally (DIY investor) or hire, against the payment of a management fee, a professional investor and find that delegation is mainly motivated by the belief that professional advisors are, depending on investment horizon and risk aversion, either better informed (‘insiders’) or more capable of gathering and processing information, rather than possessing the ability to learn from financial data. In particular, for very short investment horizons, delegation is primarily, if not exclusively, motivated by the beliefs that professional investors are better informed.     

Options trades,short sales and real earnings management

We study the link between measures of stock options’ volatility and firms’ real earnings management (RM). We hypothesise that RM causes uncertainty in the value of a firm’s common stock and, as a result, increases the volatility spread and skew of the firm’s options. Spread and skew proxy for investors’ uncertainty in the value of the options underlying a stock. Consistent with our hypothesis, we find an association between a firm’s use of RM, and the volatility spread and skew in the firm’s options, more precisely in its put options. We also study the link between short selling and the extent of RM but do not find a consistent relationship between the two.     

NUSAP: a method to evaluate the quality of assumptions in quantitative microbial risk assessment

The Numeral Unit Spread Assessment Pedigree (NUSAP) system was implemented to evaluate assumptions in a quantitative microbial risk assessment (QMRA) model for Salmonella spp. in minced pork meat. This QMRA model allows the testing of mitigation strategies for the reduction of human salmonellosis and aims to serve as a basis for science‐based policy making. The NUSAP method was used to assess the subjective component of assumptions in the QMRA model by a set of four pedigree criteria: ‘the influence of situational limitations’, ‘plausibility’, ‘choice space’ and ‘the agreement among peers’. After identifying 13 key assumptions relevant for the QMRA model, a workshop was organized to assess the importance of these assumptions on the output of the QMRA. The quality of the assumptions was visualized using diagnostic and kite diagrams. The diagnostic diagram pinpointed assumptions with a high degree of subjectivity and a high ‘expected influence on the model results’ score. Examples of those assumptions that should be dealt with care are the assumptions regarding the concentration of Salmonella on the pig carcass at the beginning of the slaughter process and the assumptions related to the Salmonella prevalence in the slaughter process. The kite diagrams allowed a clear overview of the pedigree scores for each assumption as well as a representation of expert (dis)agreement. The evaluation of the assumptions using the NUSAP system enhanced the debate on the uncertainty and its communication in the results of a QMRA model. It highlighted the model’s strong and weak points and was helpful for redesigning critical modules. Since the evaluation of assumptions allows a more critical approach of the QMRA process, it is useful for policy makers as it aims to increase the transparency and acceptance of management decisions based on a QMRA model.     

An exploration on policy uncertainty as a driver of R&D activity

We explore the relationship between uncertainty in economic policy and R&D activity for the sample of 576 firms from seven countries in the world. We base our analysis on an index of newspaper-based economic policy uncertainty (EPU) following the approach of Baker et al.’s (2016). We observe a significantly negative link between EPU and R&D intensity. Interestingly, the negative effect of policy uncertainty has less effect on the R&D activities of firms with growth opportunities. Finally, firms in politically sensitive industries respond stronger to EPU as far as R&D intensity is taken into account.     

The influence of business strategy on annual report readability

Concerns about the complexity of firm disclosures have prompted regulators to initiate projects to improve the readability of annual reports. We investigate business strategy as a determinant of annual report readability. As business strategy fundamentally determines a firm’s product and market domain, technology, and organizational structure, it influences a firm’s operating complexity, environmental uncertainty and information asymmetry. Consequently, business strategy frames the level, wording, and complexity of disclosures. We capture a firm’s business strategy based on the Miles and Snow (1978) strategic typology and measure 10-K readability with Li’s (2008) Fog index. We find that firms pursuing an innovation-oriented prospector strategy have less readable 10-Ks relative to firms pursuing an efficiency-oriented defender strategy. We also find that prospectors display more negative and uncertainty tones while defenders exhibit more litigious tone in their 10-Ks. Our study provides useful insights to policy makers as it suggests that efforts to improve annual report readability may be limited for some firms given that business strategy is a fundamental determinant of readability and pronouncements accommodating different strategic orientations are not feasible.     

The Effects of Uncertainty and Disclosure on Auditors' Fair Value Materiality Decisions

Financial accounting standards increasingly require fair value measurements. I experimentally examine how uncertainty affects auditors’ adjustment decisions when evaluating fair values. I manipulate two types of uncertainty, input subjectivity and outcome imprecision, and one reporting choice, supplemental disclosure. I find that auditors are most likely to require adjustments when fair values contain both more input subjectivity and more outcome imprecision, but that this likelihood diminishes when clients supplement recognized fair values with additional disclosure. Thus, consistent with moral licensing, I find that auditors tolerate greater potential misstatement in the financial statements when clients provide disclosure, suggesting that the SEC's preference for supplemental disclosure may have the unintended consequence of affecting fair values recognized in the body of the financial statements. I also provide evidence that auditors determine adjustment size by comparing recorded fair value to the nearest bound, rather than the midpoint, of the auditors’ own range estimate, consistent with strict application of auditing standards.     

Pension Wealth Uncertainty

Using a representative sample of Italian investors, we measure the uncertainty of social security benefits by eliciting for each individual the subjective distribution of the replacement rate as a summary indicator of pension uncertainty. We find that pension uncertainty varies across individuals in a way that is consistent with what one would expect a priori, given different information sets and pension schemes. In particular, individuals who are a long way from retirement, and thus face more career uncertainty, report more subjective pension uncertainty. Since expectations reveal information about people's understanding of pension reforms, our findings suggest that they should also be an important determinant of how people respond to reforms.     

Disagreement and the Cost of Capital

We assess how forms of disagreement among investors affect a firm's cost of capital. Firms experience a lower cost of capital if investors perceive that other investors are ignoring relevant disclosures (perceived errors of omission), but a higher cost of capital if investors perceive that others are responding to irrelevant disclosures (perceived errors of commission). The impact of these two sources of disagreement on the cost of capital is determined by the distribution of opinion and the nature of disclosure. For example, even though aggregated disclosures reveal less to investors, aggregated disclosures may decrease the cost of capital by eliminating disagreement associated with perceived errors of commission. These and additional results arise because the cost of capital is driven not only by investors’ uncertainty about the firm's future earnings performance, but also by investors’ uncertainty about the evolution of beliefs, which partly determines the path of prices.
