Tax penalties on fluctuating incomes: estimates from longitudinal data

Progressive personal income taxes can cause individuals with fluctuating incomes to pay more taxes over time than individuals with constant incomes of the same average value. The implicit tax penalty violates principles of equity and may harm efficiency by discouraging risk-taking activities, such as entrepreneurship. This paper uses longitudinal data to estimate the tax penalties in six panels of Canadian data from 1993 to 2010. The effects of various income averaging policies for mitigating tax penalties are then examined.     

On the optimal lifetime redistribution and social objectives: a multidimensional approach

We characterize optimal redistribution policy when there are differences not only in individuals’ productivities but also in their tastes towards the timing of consumption, i.e. some are patient and others impatient in consumption over the life cycle and this preference together with productivity is non-observable to government. We consider different social objectives and incorporate a novel approach taken in the spirit of Roemer (Equality of opportunity, Harvard University Press, Harvard, 1998) and Van de Gaer (Equality of opportunity and investments in human capital, Katholieke Universiteit Leuven, 1993). This approach applies a compromise between the principle of compensation and the principle of responsibility. We derive analytical expressions which describe the optimal distortion (upward or downward) in saving. As the multidimensional problems become very complicated, to gain a better understanding, we also numerically examine the properties of an optimal lifetime redistribution policy. We find support for a nonlinear tax/pension program in which impatient types are taxed at the margin, and patient low ability types are subsidized in their retirement consumption. Numerical simulations show quite big differences in terms of the levels of marginal tax rates between different social objectives, indicating that the optimal income taxation results are sensitive to the choice of the social planner’s goals.     

Oil shocks,policy uncertainty and earnings surprises

The study utilizes a structural VAR model to understand the connections among oil shocks, policy uncertainty and aggregate earnings in US. We find that the positive innovations in US oil supply increase the aggregate earnings. A rise in the US policy uncertainty decreases the aggregate earnings. After 2007 with the shale oil development in US, the earnings responses to the US oil supply shocks has increased. Over time shocks to US oil supply reduce the policy uncertainty. The development of US oil production is associated with the increase in income and the enhancement on political and economy security in US. Policy uncertainty plays an important role in the transmission of oil shocks to the earnings. The structural oil price shocks explain around 35% of the overall variations in the policy uncertainty in the long run and cause long swings in the policy uncertainty. The direct effects of oil shocks on the aggregate earnings are amplified by the endogenous responses of policy uncertainty.     

The efficiency of IPO issuing mechanisms and market conditions: evidence in China

This study conducts a comparison analysis on the efficiency of bookbuilding and secondary market proportional offering (hereafter, SMP offering) in the China stock market. SMP offering as described in this paper is not a follow-on offering, but an initial offering applicable to investors in the secondary market. Specifically, as a unique type of fixed price offering, SMP offering only allows the existing investors who are holding shares (of any listed firms) in the secondary market to subscribe to IPO shares. The amount of IPO shares available to be subscribed by the existing investors is proportional to market value of shares held by them in the secondary market. We find some interesting evidence showing that, compared with bookbuilding, SMP offering is more efficient for pricing IPOs, particularly, in a volatile market. SMP offering leads to lower underpricing and lower cross-sectional variation of short-run returns of IPOs. Also, SMP offering is better able to counteract adverse market conditions in the form of low market return and/or high market volatility. Our results are robust to various alternative tests, e.g., the Heckman (Econometrica 47:153–161, 1979) two-stage procedure and an out-of-sample test, after controlling for the problem of endogeneity and for the influence of the exchange of listing, respectively.     

Odd lot trading and earnings announcements

This study investigates odd lot trading, both trades and orders, around quarterly earnings announcements to determine whether odd lot traders are informed regarding the information contained in earnings announcements. We find pre-announcement odd lot order imbalances are not positively correlated with post-announcement returns and odd lot traders do not earn excess returns. Portfolios long stocks highly bought by odd lot traders in the pre-announcement period and short stocks highly sold by odd lot traders do not outperform the market. We conclude that odd lot traders are not in possession of earnings announcement information prior to its release to the public.     

Does corporate diversification reduce value in high technology firms?

We find that firm value is reduced via industrial diversification and this reduction in value depends upon a firm’s technology intensity. We consider that asymmetric information problems are more severe in technology intensive industries and find that high tech industry firms present distinctly larger value reduction when compared to low tech industry firms. The negative valuation effect is greater for firms that have a relatively larger amount of intangible assets and greater R&D capital. We determine that our findings are robust to different estimation methods and alternative excess value measures.     

Classical meets modern in the IDEA protocol for structured expert judgement

Expert judgement is pervasive in all forms of risk analysis, yet the development of tools to deal with such judgements in a repeatable and transparent fashion is relatively recent. This work outlines new findings related to an approach to expert elicitation termed the IDEA protocol. IDEA combines psychologically robust interactions among experts with mathematical aggregation of individual estimates. In particular, this research explores whether communication among experts adversely effects the reliability of group estimates. Using data from estimates of the outcomes of geopolitical events, we find that loss of independence is relatively modest and it is compensated by improvements in group accuracy.     

Decomposing the market,industry, and firm components of profitability: implications for forecasts of profitability

Academics and practitioners frequently highlight that overall market and industry performance is an important aspect of a firm’s profitability. However, few studies allow for the decomposition of a firm’s profitability into market, industry, and idiosyncratic components, and those that do often assume that the market and industry components are cross-sectional constants. In this study, we allow for variation in firm-specific sensitivities to market, industry, and idiosyncratic economic shocks, and then assess whether and when this decomposition results in improved forecasts of profitability. For the overall sample, we find significant improvements in terms of the magnitude of forecast errors and the frequency with which forecasts based on the decomposed values are superior versus forecasts using only total profitability. Across the sample as a whole, decomposing profitability in the forecasting process results in more accurate forecasts greater than two-thirds of the time (increasing to almost 80% within certain subsamples). Our results provide strong support for the role that firm-specific measures of market and industry profitability play in predicting a firm’s future performance, as well as highlighting settings where the decomposition provides the greatest benefit in terms of predicting future changes in profitability.     

Debt contracts in the presence of performance manipulation

Empirical evidence suggests that firms often manipulate reported numbers to avoid debt covenant violations. We study how a firm’s ability to manipulate reports affects the terms of its debt contracts and the resulting investment and manipulation decisions that the firm implements. Our model generates novel empirical predictions regarding the use and the level of debt covenant, the interest rate, the efficiency of investment decisions, and the likelihood of covenant violations. For example, the model predicts that the optimal debt contract for firms with relatively strong (weak) corporate governance (i.e., cost of manipulation) induces overinvestment (underinvestment). Moreover, for firms with strong (weak) corporate governance, an increase in corporate governance quality leads to tighter (looser) covenant, more (less) frequent covenant violations and lower (higher) interest rate. Our model highlights that the interest rate, which is a common proxy for the cost of debt, neither accounts for the distortion of investment efficiency nor the expected manipulation costs arising under debt financing. We propose a measure of cost of debt capital that accounts for these effects.     

Audit personnel salaries and audit quality

This study examines the relation between audit personnel salaries and office-level audit quality. We measure audit personnel salaries at the associate, senior, and manager ranks for Big 4 audit offices from 2004 to 2013, using unique individual-auditor-level data obtained from the U.S. Department of Labor. We find that offices that pay lower salaries have a higher percentage of clients that experience restatements. In related analyses, we also find lower levels of audit quality when audit employees are paid less, relative to other lines of service in accounting firms. Finally, we document positive and significant associations between salary and fees, suggesting that audit offices pass some of the cost of higher labor onto their clients. Overall, our findings provide important initial evidence on the role of audit salary and its relation to audit quality and audit fees.
