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.     

International Diversification,SFAS 131 and Post‐Earnings‐Announcement Drift

Using 1990 through 2013 data of U.S. firms with foreign operations, we show that (i) the serial correlation of analyst forecast errors increases in the extent of international diversification, (ii) post‐earnings‐announcement drift (PEAD) based on analyst forecast errors increases in the extent of international diversification, and (iii) the impact of international diversification on the serial correlation of analyst forecast errors and its associated drift is significantly reduced after the implementation of SFAS 131 on segment disclosures. When we replicate our tests using seasonally differenced earnings, we fail to observe similar patterns. Overall, our results suggest that investors’ underreaction to announced earnings is a likely explanation for PEAD. Our findings also indicate that disclosures required under SFAS 131 are useful to analysts in forming efficient earnings expectations, thereby helping capital market participants in the pricing of internationally diversified firms’ earnings.     

Accounting Quality,Liquidity Risk,and Post‐Earnings‐Announcement Drift

Recent microstructure research finds that liquidity risk, in particular its information component, plays an important role in explaining the post‐earnings‐announcement drift (PEAD). We decompose liquidity risk into an accounting‐associated component and a nonaccounting‐associated component and examine their relative importance in explaining PEAD. Our research is motivated by recent findings that liquidity risk is a systematic risk and earnings quality is negatively associated with liquidity risk. We find that the accounting‐associated component is more strongly related to PEAD returns than is its nonaccounting‐associated counterpart. Further analyses reveal that the relation between accounting‐associated liquidity risk and PEAD returns is weaker for firms with greater analyst following. We also find that in a significant market downturn, the relation between accounting‐associated liquidity risk and PEAD returns becomes more pronounced. Our study is the first to document a liquidity risk‐based role of accounting quality in explaining the PEAD phenomenon. It parses out the PEAD risk premia associated with accounting versus nonaccounting sources and, by so doing, sheds light on the role of accounting quality in shaping the liquidity risk‐PEAD returns relation.     

Intra‐Industry Information Transfers and the Post‐Earnings Announcement Drift

This study examines the role of intra‐industry information transfers in the analyst forecast‐based post‐earnings announcement drift. I find that subsequent same‐industry‐peer earnings announcements influence a firm's post‐earnings announcement drift if these subsequent announcements confirm the firm's initial earnings surprise and the firm's industry exhibits ex ante positive (common effect) intra‐industry information transfers. The results suggest that underreaction to industry‐specific information contributes to analyst forecast‐based post‐earnings announcement drift.     

Aggregation,Dividend Irrelevancy,and Earnings‐Value Relations*

In this paper I show that the aggregation of operating and financial income imposes three conditions on earnings‐based value functions. These three conditions provide a shortcut way to identify dividend irrelevant value functions. For example, consider any value function V_t of book value b_t, earnings x_t, and dividends d_t. The aggregation conditions imply that V_t must be of the form V_t = (1 ? k)bt + k [f xt ? dt]. f is the permanent earnings capitalization factor and undetermined weight k may be any function of Δ_t ≡[φx_t ? d_t] ? b_t. The Ohlson 1995 model is the special case when k is constant. But generally k does not have to be constant to maintain dividend irrelevancy. Whenk varies with Δ_t, V_t is nonlinear in earnings. Hence, this result specifies how V_t may be nonlinear in earnings in settings with limited liability or production or abandonment options and still be dividend‐irrelevant. An even more remarkable feature of this result is that it holds whether accounting is clean surplus or not. One must conclude that accounting‐based valuation properly builds from accounting aggregation and Δ_t, and not from the clean surplus relation and abnormal earnings as many now believe.     

Post‐Injury Work Outcomes Revisited

We use data for Ontario workers with permanent impairments resulting from work‐related injuries to investigate the complex relationships among post‐injury work outcomes: wages, accommodations, returning to the same or different employer, and duration of work absence. We argue the different aspects of post‐injury work experience may be jointly determined, making post‐injury job characteristics endogenous in a duration model. To explore the endogeneity issues we instrument post‐injury job variables from first‐stage equations and compare results from this “informed” model to a “naive” model that treats the variables as exogenous. We find that returning to one's pre‐injury employer is associated with more favorable post‐injury work outcomes, including higher wages, greater likelihood of job accommodations, and shorter durations of work absence relative to workers who change employers. We also find substantial differences between the naive and informed models, with accommodations having the predicted negative effect on duration only after we control for endogeneity.     

Post‐IFRS Revaluation Adjustments and Executive Compensation

International Financial Reporting Standards (IFRS) allow firms to record adjustments (gains or losses) from the revaluation of investment properties in their income statements. After Hong Kong adopted IFRS in 2005, property companies were required to move their revaluation gains and losses (RGL) from equity to income. We find RGL to be a significant determinant of executive compensation in these firms after 2005, but not before. We further find evidence that the RGL‐compensation association is driven by firms with relative weak corporate governance structure, such as firms in which the controlling shareholders own a relatively small percentage of shares, firms in which the controlling shareholders have control rights that exceed ownership rights, and firms that are no longer run by their founders.     

Operational Restructuring Charges and Post‐Restructuring Performance*

Firms incur restructuring charges as a result of actions intended to improve their operating performance. However, there is little evidence on whether restructuring charges are associated with improved performance. We examine a sample of firms reporting restructuring in 1991‐93 and find that the restructuring firms' earnings increase over the levels immediately before restructuring. Compared with a control sample of firms that report no restructuring, the restructuring firms improve their earnings and operating income, but evidence for improvements in cash flow from operations is mixed. In regression analysis, we find that restructuring charges are significantly positively associated with post‐restructuring changes in earnings relative to the restructuring year, but this association is largely driven by firms with multiple restructurings and firms reporting losses in the restructuring year. We find no association between restructuring charges and post‐restructuring changes in earnings relative to the year before restructuring. Restructuring charges are significantly positively associated with post‐restructuring changes in operating income and cash flow from operations for firms with multiple restructurings. In summary, restructuring charges are associated with improved earnings, but our results suggest that restructuring in the early 1990s did not necessarily guarantee improved operating performance.     

Prices and real wages in seventeenth‐century Madrid

This article focuses on the evolution of real wages earned by building labourers and craftsmen in Madrid during the seventeenth century. After a substantial rise brought about by the arrival of the Court in 1561, real wages experienced a remarkable fall from 1621–30 onwards. Our thesis is that the fiscal and monetary policies pursued by the Crown to fund its ambitious imperial policy exerted a clear influence on this decline. The currency manipulations of the low‐value petty coin (maravedí) drove serious losses in the real wages of building labourers and craftsmen between 1621 and 1680. In the years around 1665 the real wages of both groups had fallen below the levels of 1561–1600, and the indirect taxes levied by the Crown and the town council contributed to keeping real wages stagnant at around the low levels of 1665–80 between 1681 and 1700. Although this issue merits further research, it seems unlikely that building labourers and craftsmen could have offset the decline in their real wages through an increase in the number of hours worked or a rise in the number of work days.     

Trade‐Induced Unemployment: The Case of Post‐Apartheid South Africa

This paper analyses the link between changes in trade flows and labour demand in post‐apartheid South Africa (1994–2006). Although this is not the first research with regard to this topic, it is one of the few that uses a consistent trade framework. Based on a three‐dimensional Heckscher–Ohlin trade model, a theoretical framework is constructed to analyse this link. Whereas it is impossible to test the theoretical link directly because of data limitations, an indirect econometric test supports the findings of the model. This implies that the combination of increased trade and labour market rigidities was unfavourable for labour opportunities.     

Development of Public Housing in Post‐reform China

This paper explores the dynamic nature of the transformation of public housing regimes in urban China since the abolishment of the urban welfare housing system in the late 1990s. We summarize the latest progress in the development of public housing in post‐reform China and investigate the driving forces behind these developments. A close examination of the public rental housing program in Shanghai helps to show that the recent revival of public housing in Chinese cities is mostly driven by the desire for economic growth. We conclude that the state provision of housing could be a short‐run state remedy to alleviate economic imbalance and social inequality. However, in the long run China needs to seek more effective solutions to solve the low‐income population's housing affordability problems.     

Price‐Setting Behaviour in Lesotho: Stylised Facts from Consumer Retail Prices

This paper documents some of the main features of price‐setting behaviour by retail outlets in Lesotho over the period March 2002 to December 2009. These features include the frequency, size, duration and synchronisation of price changes. In addition, the paper compares price‐setting behaviour in Lesotho and South Africa using a comparable set of products. The findings reveal considerable heterogeneity in price‐setting behaviour across products, outlets, locations and time. Variations in inflation are strongly correlated with the average size of price changes, but rising inflation raises the frequency of price increases and reduces the frequency of price decreases. Price decreases constitute an important determinant of inflation movements. Surprisingly, the frequency and size of price changes in Lesotho differ substantially from those in South Africa, despite the presence of common retail chains and their joint membership in a customs union and common monetary area. These findings open up opportunities for further research into the sources of heterogeneity across products and Lesotho and South Africa in the setting of prices.     

Cheating and Enforcement in Asymmetric Rank‐Order Tournaments

In rank‐order tournaments, undesirable but output‐enhancing activities, such as cheating, may occur. Cheating may be especially tempting when one player has an advantage over another. We show that when audit probabilities are low (high), the leading (trailing) player has more incentive to cheat. Furthermore, we show that “correlated” audits are more effective at decreasing the frequency of cheating than independent audits. Finally, we show that differential monitoring schemes, where contestants are audited based on either their initial position or final ranking, more efficiently achieve full deterrence than schemes that monitor contestants with equal probability.     

Weathering the Storm: Measuring Household Willingness‐to‐Pay for Risk‐Reduction in Post‐Katrina New Orleans

The city of New Orleans suffered extensive damage as a result of Hurricane Katrina. Rebuilding involves decisions on investment in protective measures. An exhaustive list of protective measures has been studied in planning documents, with public comment solicited in town hall meetings. In this study we employ a different approach to examine public sentiment toward the selection and investment in protective measures. Our study uses a stated preference choice experiment with a stratified sample to investigate individuals' willingness‐to‐pay for rebuilding New Orleans's man‐made storm defenses, restoring natural storm protection, and improving evacuation options through a modernized transportation system. We target residents of the New Orleans metropolitan area as well as other U.S. citizens. Our results indicate that individuals are willing to pay for increased storm protection for New Orleans, but values differ among residents of the New Orleans metropolitan area and other U.S. citizens.     

Relating Product Prices to Long‐Run Marginal Cost: Evidence from Solar Photovoltaic Modules

A basic tenet of microeconomics is that for a competitive industry in equilibrium the market price of a product will be equal to its marginal cost. This paper develops a model framework and a corresponding empirical inference procedure for estimating long‐run marginal cost in industries where production costs decline over time. In the context of the solar photovoltaic (PV) module industry, we rely primarily on firm‐level financial accounting data to estimate the long‐run marginal cost of PV modules for the years 2008–2013. During those years, the industry experienced both unprecedented price declines and significant expansions of manufacturing capacity. We compare the trajectory of average sales prices with the estimated long‐run marginal costs in order to quantify the extent to which actual price declines were attributable to reductions in production costs. The trajectory of estimated product costs is then extrapolated to forecast an equilibrium trend line for future PV module prices.     

Robust Estimates of Changes in Poverty and Inequality in Post‐Independence Namibia

We estimate changes in the distribution of household consumption expenditure in Namibia since independence in 1990 and the effects on poverty. To produce comparability between two household surveys, we use survey‐matching techniques, and we apply the framework of stochastic dominance to test the robustness of our results. The results reveal a significant decrease in the poverty headcount over the period and small but insignificant decreases in the country's extremely high levels of inequality. Decomposition analysis shows that poverty reduction in Namibia is largely driven by growth in mean incomes rather than redistribution. Even so, there have been important changes in inequality among different social groups especially as educational attainment has replaced ethnicity as the main determinant of between‐group inequality.     

Asymmetric Price Adjustment: Cross‐Industry Evidence

Several studies document asymmetric price adjustment in gasoline and agricultural markets. Do these results extend to other subsectors of the economy? This paper investigates the existence of asymmetric price adjustment in 269 6‐digit North American Industrial Classification System (NAICS) industries using quarterly financial data from 1966–2006. Results, which are consistent with the previous literature, show that positive price asymmetry is frequent in nondurable goods and natural resource manufacturing. However, price asymmetry is not readily evident in mining, durable goods manufacturing, and service sectors. The differing results may best be explained by theoretical explanations of price asymmetry based on inventory management.
