An Empirical Analysis of the Effects of Online Trading on Stock Price and Trading Volume Reactions to Earnings Announcements*

This study provides evidence regarding the effects of online trading on stock price and trading volume reactions to quarterly earnings announcements. We test for differences in stock price and volume reactions to quarterly earnings announcements between a period with a significant amount of online trading (1996‐99) and a period without online trading (1992‐95). We conjecture that online trading has increased the proportion of naive investors in the market. We predict that this will result in (1) a decrease in the average precision of investor information prior to earnings announcements leading to higher earnings response coefficients (ERCs), (2) an increase in differential interpretation of earnings leading to higher trading volume reactions that are unrelated to price change, and (3) a decrease in differential prior precision leading to a decrease in the association between trading volume and absolute price change. We find evidence consistent with all three predictions. Our findings are relevant for assessing the validity of concerns about online trading expressed by regulators and the validity of theoretical models of trade with asymmetrically informed investors.

Is there a trade-off between the employment and wages of unskilled African South Africans?

The possible trade-off between employment and wages has characterised most of South Africa’s labour market debates, particularly with regards to decent wages versus unemployment. In this article we explore the relationship between labour market earnings and the level of employment among African birth cohorts using labour force data from 1997 to 2011. We find that the association between an increase in the proportion of unskilled employed in a birth cohort and earnings is mediated by the sector of employment. While some sectors exhibit the expected negative association, there is a robust positive relationship between the first two quartiles of the earnings distribution within birth cohorts and the proportion of the birth cohort who are employed in unskilled occupations in the manufacturing and trade sectors. Because a range of market forces determine this relationship, further research is needed to unpack the reasons for such varied outcomes in order to better inform the debates on labour market interventions like the proposed National Minimum Wage and to appreciate the potential impact of such policy interventions on wages and employment.     

Are Investors Misled by “Pro Forma” Earnings?*

This paper uses stock market data to investigate the popular claim that investors are misled by the “pro forma” earnings numbers conspicuously featured in the press releases of some U.S. firms. We first document the frequency and magnitude of pro forma earnings in press releases issued during June through August 2000, and describe the 433 firms that engaged in this financial disclosure strategy. Our test period predates public expressions of concern by trade associations and regulators that pro forma earnings may mislead investors and the subsequent issuance of guidelines and rules on the disclosure of pro forma earnings numbers. We use two complementary approaches to determine whether the share prices that investors assign to pro forma firms are systematically higher than the prices assigned to other firms. Our market‐multiples tests for differences in price levels find some evidence suggesting that pro forma firms may be priced higher than firms that do not use the disclosure strategy. This apparent overpricing is not, however, related to the pro forma earnings numbers themselves. Our narrow‐window stock returns tests reveal no evidence of a stock return premium for pro forma firms at the quarterly earnings announcement date. Collectively, the results cast doubt on the notion that investors are, on average, misled by pro forma earnings disclosures despite the widespread concern expressed in the financial press and by regulators.     

Export subsidies and minimum access guarantees in agricultural trade: a developing country perspective

The paper presents a framework for and results from a quantitative analysis of two proposals to GATT, made as part of an effort at containing or rolling back the spread of non-tariff barriers in agriculture. The first proposes export subsidies, which would be financed by the producers themselves, requiring no government outlay. The second calls for a minimum access for importers. This analysis examines the magnitude of the effects on trade flows, world prices, the impact on the production, consumption, and trade of the OECD countries and on foreign exchange earnings of less developed countries (LDCs), of minimum access as applied to sugar trade — one of the most protected products in OECD countries and one with great potential for LDC exporters. Results are then compared with an analysis of more comprehensive trade liberalization in the sugar market, i.e., complete removal of trade barriers in all OECD countries.     

International specialization and structural change in the Swedish Manufacturing Industry, 1969–1992

International Specialization and Structural Change in the Swedish Manufacturing Industry, 1969–1992. — The increasing trade orientation of Swedish manufacturing 1969–1992 was mainly caused by increasing intraindustry specialization with most industries. Intraindustry specialization was found to be related positively to the skill intensity of the industry and negatively to average plant size and the incidence of trade barriers. The paper evaluates the links between specialization and inter-as well as intraindustry structure. It was found that changing patterns of relative international competitiveness among industries accounted for more than half of the total interindustry structural change in employment in 1969–1992. The mean plant size tends to increase with intraindustry specialization.     

The reaction of Canadian securities to revisions of earnings forecasts*

Abstract. This first study of Canadian securities' earnings forecasts published by Institutional Brokers Estimate System (IBES) focuses on changes in the mean earnings per share forecasts of 159 to 188 companies from 1985 to 1987. Cumulative average residuals are used to detect the announcement effects of large earnings forecast revisions. The main results of this study are the following. First, an investor with access to changes of earnings per share forecasts at the beginning of the month of publication could realize abnormal excess returns. Second, trading strategies based on earnings forecasts revisions can also yield abnormal returns, but the magnitude of the revision, the sector of the company, and the month in which the revision is realized must be considered. Third, when financial analysts' forecasts are published, the informational content of large revisions in forecasts has already been discounted by the market. This result is similar to findings of U.S.– and U.K.–based studies. Finally, large forecasts revisions coincide with a period of abnormal returns. However, the information content of the announcement of forecasts changes cannot be established. The gains are larger if the trade is undertaken before the diffusion of the forecast revision to the IBES subscribers. These results do not vary with the model chosen to predict company returns. This does not necessarily indicate the existence of a market inefficiency because information acquisition and analysis costs, as well as transaction costs, may diminish considerably these abnormal trading gains.     

Equilibrium Earnings Management,Incentive Contracts,and Accounting Standards*

In this paper, we model earnings management as a consequence of the interaction among self‐interested economic agents ‐ namely, the managers, the shareholders, and the regulators. In our model, a manager controls a stochastic production technology and makes periodic accounting reports about his or her performance; an owner chooses a compensation contract to induce desirable managerial inputs and reporting choices by the manager; and a regulatory body selects and enforces accounting standards to achieve certain social objectives. We show that various economic trade‐offs give rise to endogenous earnings management. Specifically, the owner may reduce agency costs by designing a compensation contract that tolerates some earnings management because such a contract allocates the compensation risk more efficiently. The earnings‐management activity produces accounting reports that deviate from those prescribed by accounting standards. Given such reports, the valuation of the firm may be nonlinear and s‐shaped, thereby recognizing the manager's reporting incentives. We also explore policy implications, noting that (1) the regulator may find enforcing a zero‐tolerance policy ‐ no earnings management allowed ‐ economically undesirable; and (2) when selecting the optimal accounting standard, valuation concerns may conflict with stewardship concerns. We conclude that earnings management is better understood in a strategic context that involves various economic trade‐offs.     

Who is Better Off from Trade Liberalization? An Experience from Urban China*

Empirical studies have found that the skill wage gap (difference between wages earned by skilled and unskilled workers) narrowed in the case of the ‘Four Asian Dragons’ as they underwent trade liberalization during the 1960s and 1970s, whereas the gap widened in most of the Latin American countries after they liberalized their economies in the 1980s. China's integration into the world economy since 1978 has been used to explain this phenomenon, but few formal studies have been carried out in China regarding the effects of trade liberalization on the skill wage gap because of the limited availability of data. The present study uses unique household surveys conducted in ten provinces of China in 1988 and 1995 to study this issue. Results show that trade liberalization that occurred in China between 1988 and 1995 was responsible for an average increase of 28.73 yuan (approximately 20 percent of the total increase) in average monthly wages. However, trade liberalization significantly widened the urban skill wage gap in China by introducing an increase in income only for those who had 13 years or more of education (at least junior high school graduates). Interestingly, import liberalization also only benefited those who had more than 9 years of schooling; whereas export liberalization brought wage increases for people with 7–12 years of education. Finally, those with specific production skills from technical schools, rather than those with several years of general education, were mostly favored in the labor market in China between 1988 and 1995.     

Does Tax Planning Affect Analysts' Forecast Accuracy?

We investigate whether firms' tax planning affects the accuracy of analysts' forecasts. Tax planning can exacerbate the complexity of firms' operations through strategic choices to exploit tax laws. Because of its effect on firms' operations, tax planning can influence analysts' efforts to understand and forecast earnings. Specifically, if the additional complexity arising from tax planning makes firm attributes less representative of expected earnings, analysts may issue less accurate forecasts. Using auditor‐provided tax services (APTS) as a measure of tax planning, we find that, as firms spend more on tax planning, the accuracy of analysts' forecasts of both earnings per share and tax expense declines. We also document that firms with higher levels of APTS have greater year‐to‐year volatility in, and lower persistence of, effective tax rates and earnings. Our results suggest that increased firm complexity, due to greater tax planning, makes earnings and tax expense more difficult to forecast and that analysts do not properly adjust for these effects. Thus, when deciding to engage in tax planning, firms appear to make trade‐offs between potential tax savings and negative effects on earnings properties and analysts' forecasts.     

Investor Overreaction to Earnings Surprises and Post‐Earnings‐Announcement Reversals

Prior literature suggests that the market underreacts to the positive correlation in a typical firm's seasonal earnings changes, which leads to a post‐earnings‐announcement drift (PEAD) in prices. We examine the market reaction for a distinct set of firms whose seasonal earnings changes are uncorrelated and show that the market incorrectly assumes that the earnings changes of these firms are positively correlated. We also document that positive (negative) seasonal earnings changes in the current quarter are associated with negative (positive) abnormal returns in the next quarter. Thus, we observe a reversal of abnormal returns, consistent with a systematic overreaction to earnings, rather than the previously documented PEAD. Additional analysis indicates that financial analysts similarly overestimate the autocorrelation of these firms, although to a lesser extent. We also find that the magnitude of overestimation and the subsequent price reversal are inversely related to the richness of the information environment. Our results challenge the notion that investors recognize but consistently underestimate earnings correlation and provide a new perspective on the inability of prices to fully reflect the implications of current earnings for future earnings. That is, we show that investors predictably overestimate correlation when it is lacking, but underestimate it when it is present.     

The Timeliness of the Bond Market Reaction to Bad Earnings News

We find that bond price quotes impound bad earnings news on a more timely basis than good earnings news and that the bond market impounds bad news on a more timely basis than the stock market. We also find that the timeliness of the bond market reaction to bad news is concentrated primarily among speculative‐grade bonds, consistent with earnings news having a larger effect on bond price quotes when default risk is high. In addition, we find that a portion of the bad news impounded by the bond market reverses following the earnings announcement. Overall, our findings are consistent with bondholders’ asymmetric payoff function having important implications for the valuation role of accounting information in the bond market. Specifically, our findings indicate that bond quotes impound bad earnings news much earlier in the pre‐earnings announcement period than stock prices. In addition, bondholders appear to overreact to the bad earnings news initially and correct this overreaction subsequent to the earnings announcement.     

The Effect of Short Selling on Market Reactions to Earnings Announcements*

This paper examines the effect of the inherent demand implied by short interest by studying how stock price reactions to earnings announcements depend on the level of short interest. We find that, for extreme good and bad news events, the inherent demand increases stock prices around the earnings announcement date, with the effect being stronger for good news relative to bad news. Specifically, the initial market reaction to an extreme positive earnings surprise is larger for firms with high levels of short interest. On the other hand, for an extreme negative earnings surprise event, the initial market reaction is less negative for heavily shorted firms. Furthermore, we find that the post‐earnings‐announcement drift is smaller (larger) in magnitude for extreme positive (negative) earnings surprises for the heavily shorted firms.     

Gender earnings differentials in Taiwan: A stochastic frontier approach

We examine Taiwan's male–female earnings gaps over the past three decades in order to assess the progress in assimilating women into the labor market. Two alternative methods of evaluating earnings gaps are employed in this paper: the traditional Oaxaca–Blinder decomposition method and the less well-known method of evaluating labor market efficiency. Men and women's earnings are converging during this period (1978–2003) while at the same time there is little change in the level of gender discrimination measured by the standard Oaxaca–Blinder method. Using the labor market efficiency (stochastic frontier) model we find increases in labor market efficiency over time for both males and females; however, females enjoy a much faster rate of increase in efficiency. We conclude that the relative increase in female efficiency represents a decline in discrimination against females.     

Does Ethnicity Matter for Access to Childhoodand Adolescent Health Capital in China? Evidence from the Wage-Height Relationship in the 2006 China Health and Nutrition Survey

This paper considers whether ethnicity conditions the return and access to health capital in China. Given that the wage-height relationship reflects the labor market earnings returns to childhood and adolescent health capital, differences in the labor market returns to height by ethnicity reflect ethnic differences in access to health capital during childhood and adolescence. We theoretically motivate the role of height in earnings by providing a Bioeconomic rationale for stature and height determining individual wages, and estimate height-augmented Mincerian earnings functions with data from the 2006 China Health and Nutrition Survey. Our results show that when the effects of unobserved genetic influences on adult height are accounted for, the labor market return on height is higher for Chinese ethnics. This suggests that in China there are ethnic disparities in access to the inputs that produce childhood and adolescent health capital.     

Always egalitarian? Australian earnings inequality 1870–1910

We document the origins of Australia's egalitarianism by quantifying both the level and trends of earnings inequality during 1870–1910 by constructing social tables for earnings, thus overcoming the constraints imposed by the lack of income, tax and wealth data. We find that earnings inequality was much lower in Australia than in the United States and the United Kingdom in 1870 and that there was no rise in Australian earnings inequality over the half century 1870–1910, but rather a fall. We argue that such findings are driven by a faster skill supply growth relative to demand.     

Earnings Announcements and Market Depth*

Abstract. This paper investigates how strategic trading around the time of earnings announcements affects market liquidity (e.g., bid-ask spreads). We model an investor with private information in advance of an earnings announcement (e.g., inside information). The investor trades before and after the earnings announcement in a market populated by liquidity-motivated traders who have some discretion over the timing of their trades. The main result of the analysis is that an earnings announcement that reduces an insider's private information may lead to a less liquid market in the postannouncement period.     

Ill-intentioned or well-intentioned: earnings management and trade credit

The use of trade credit as important short-term financing for firms is increasing. This study explores the differential impact of firm earnings management on trade credit financing under different motives, using A-share listed firms in China from 2009 to 2020. The results show that accrued and real earnings management reduce a firm's trade credit. On the other hand, the classification shifting earnings management increases a firm's trade credit. Accrued and real earnings management are opportunistically motivated, while classification shifting earnings management is non-opportunistically motivated. Moreover, external audits weaken the negative effect of accrued and real earnings management on trade credit and enhance the positive effect of classification shifting earnings management on trade credit, indicating the ‘bilateral matching effect’ between external audits and firms. Finally, financing constraints weaken the impact of earnings management on trade credit.     

March Market Madness: The Impact of Value‐Irrelevant Events on the Market Pricing of Earnings News

Each year, the NCAA basketball tournament (March Madness) is a daytime distraction for millions of people, providing a largely exogenous shock to investor attention. We investigate whether March Madness influences the market response to earnings by diverting investor attention away from earnings news. We find that the price reaction to earnings news released during March Madness is muted. This result generally holds across several samples and additional analyses. We also find that the result is more muted for low institutional ownership firms, consistent with the effect being driven by less‐sophisticated investors. Furthermore, we find that it takes the market 30 to 60 days to correct for the distraction effect. Overall, we provide a unique test of the theory of limited attention by documenting that extraneous events can have a significant impact on the pricing of earnings.     

Recent changes in developing country exports

Conclusions Using statistics on developing country exports of the component products of key processing chains, this study found that the value of these shipments increased considerably over the period 1964–1974. Further, this increase was accompanied by some deconcentration as LDC exports are now composed of higher percentages of semi-finished and manufactured goods. However, the trade data also reveal an erosion of developing country market shares which produces a sizable annual loss in foreign exchange earnings. While further research aimed at identifying factors leading to the declining market shares should receive high priority, the magnitude of the associated trade loss indicates the potential dangers of neglecting traditional exports.
