Optimal order placement in limit order markets

To execute a trade, participants in electronic equity markets may choose to submit limit orders or market orders across various exchanges where a stock is traded. This decision is influenced by characteristics of the order flows and queue sizes in each limit order book, as well as the structure of transaction fees and rebates across exchanges. We propose a quantitative framework for studying this order placement problem by formulating it as a convex optimization problem. This formulation allows the study of how the optimal order placement decision depends on the interplay between the state of order books, the fee structure, order flow properties and the aversion to execution risk. In the case of a single exchange, we derive an explicit solution for the optimal split between limit and market orders. For the general case of order placement across multiple exchanges, we propose a stochastic algorithm that computes the optimal routing policy and study the sensitivity of the solution to various parameters. Our algorithm does not require an explicit statistical model of order flow but exploits data on recent order fills across exchanges in the numerical implementation of the algorithm to acquire this information through a supervised learning procedure.     

EVENT STUDY METHODS AND EVIDENCE ON THEIR PERFORMANCE

Abstract. The paper outlines widely used methods of estimating abnormal returns and testing their significance, highlights respects in which they differ conceptually, and reviews research comparing results they produce in various empirical contexts. Direct evidence on the performance of different methods is available from simulation experiments in which known levels of abnormal return are added. The market model is most commonly used to generate expected returns and no better alternative has yet been found despite the weak relationship between beta and actual returns. Choice of procedure for significance testing depends on the characteristics of the data. The evidence indicates that in many cases the best procedure is to standardise market model abnormal returns by their time series standard errors of regression and use the t -test. Alternatively a rank test appears to be at least as powerful. If errors are cross-correlated or increase in variance during the test period, other methods discussed should be used.     

Corporate disclosure, cost of capital and reputation: Evidence from finance directors

The majority view of the executives interviewed is that disclosure reduces the cost of equity up to the point at which a good-practice level of communication has been reached, after which there is little further effect. Greater disclosure to rating agencies and lenders reduces the cost of debt. Attitudes towards more mandatory disclosure are mostly negative. The main perceived cost of disclosure is creating the information. The main benefits are promotion of a reputation for openness and of shareholder confidence, not a lower cost of capital. We suggest that a reputation for openness is valued because it enhances the company's overall reputation, which brings commercial benefits.     

The Cost of Diversity: Endogenous Property Rights and Growth

Well-specified property rightsenhance economic performance but vary considerably across countries.The failure of numerous nation-states to adopt growth-enhancinginstitutions is paradoxical. This paper examines the role ofethnic and linguistic diversity in retarding the developmentof growth-enhancing property rights and in-turn economic growth.The data show that property rights are attenuated in more diversepolities and economic growth is correspondingly lower.     

Evaluating Permanent Disability Ratings Using Empirical Data on Earnings Losses

Workers' compensation systems are typically designed to assign higher permanent disability benefits to workers with more severe disabilities. However, little or no scientific work exists to guide the design of ratings systems to properly account for the amount of earnings power lost due to disability. In this article, we examine the effectiveness of disability ratings using matched administrative data on ratings and earnings for a large, representative sample of permanent disability claimants in California. We find that while workers with higher ratings do experience larger earnings losses on average, there are large and persistent differences in average earnings losses for similarly rated impairments in different parts of the body. We then explore how adjusting permanent disability ratings to reflect cross-impairment differences in earnings losses can affect the equity of permanent disability benefits. Adjusting disability ratings to account for typical earnings losses reduces cross-impairment differences substantially. The adjusted ratings result in a more equitable distribution of disability benefits across workers with different impairments.     

Audit committee characteristics and investment in internal auditing

Regulators and others recently highlighted the increasingly important role of internal auditing in supporting and interacting with the audit committee to ensure the integrity and quality of financial reporting. Likewise, one of the roles of the audit committee is to oversee the quality of monitoring mechanisms implemented by the firm, which includes the internal audit function. However, our understanding of the relationship between the audit committee and internal auditing is limited. We fill this void by providing the first empirical evidence of the association between audit committee characteristics and the investment in internal auditing. Our analyses, from a sample of 181 SEC registrants, suggest that the investment in internal auditing (internal audit budget) is negatively related to the presence of auditing experts on the committee and the average tenure of audit committee members, but positively related to the number of audit committee meetings (a proxy for audit committee diligence). These observations suggest potential complementary and substitution effects between the audit committee and internal auditing, and thus raise important implications for future research.     

Optimal annuitization with imperfect information about insolvency risk

Even the highest‐rated life‐annuity providers have a nonzero probability of becoming insolvent during an annuitant's retirement, and many potential annuitants are unaware of the state guaranty associations (SGAs) which provide insurance against the associated financial consequences. We study the theoretical implications of insolvency risk—real and perceived—for annuitization. Then, using a disciplined calibration of annuitant misperceptions in a standard life cycle model, we show that even the modest perceived risk of default associated with highly‐rated providers can—absent awareness of the SGAs—reduce annuitization and significantly reduce welfare. We further consider the implications of information frictions which prevent retirees from discerning true insolvency risk and we find that these frictions have plausibly large additional quantitative implications for annuitization and welfare. Simulations of our model further suggest that the general lack of awareness of the SGA backstop by potential annuitants can erode a sizable fraction of the potential welfare benefits thereof.     

Challenges in Measuring Poverty and Understanding its Dynamics: A South Asian Perspective

South Asia’s success at reducing poverty does not imply that the topic has become passé. Poverty rates are by now low, but this is because poverty lines are low as well. And the assessment of living standards and their dynamics are blurred by measurement and interpretation challenges. This paper relies mostly on South Asian examples to highlight four tensions: poorer versus richer households, rural versus urban locations, monetary versus non‐monetary dimensions of wellbeing, and household characteristics versus context. The discussion is conducted against the backdrop of the two analytical approaches with South Asian roots that have shaped the debate for decades. This review leads to three main recommendations: household survey data has to be exploited in a more thorough manner, data that is increasingly available from other sources needs to be incorporated more systematically in the analysis, and the multiple dimensions of wellbeing should be better integrated in a common framework.     

The evolving relation between dividends and flexible payouts: A different evolution

We study payout by UK listed companies during 1993–2018. Regular dividends remain the dominant channel, but flexible payouts (special dividends and repurchases) have grown, and they make total payout more responsive to earnings. Flexible payouts are used to augment regular dividends: few companies pay out by flexible means only, and tests indicate that they augment rather than replace regular dividends. Comparison with US evidence shows that UK companies make greater use of dividends (including specials) in relation to repurchases, and have a greater willingness to change regular dividend per share.     

Perceived Product Sizes in Visually Complex Environments

Although prior scholarship has demonstrated important effects of visual complexity on product perceptions, the relationship between the visual complexity of a product’s environment and that product’s perceived size remains unexplored. Because size is such an important product characteristic in many consumer contexts, the lack of exploration of this relationship leaves a significant gap in the literature on size perceptions, especially in relation to the retailing domain. The present investigation seeks to document the relationship between environmental visual complexity and the perceived size of a product. Namely, five studies show that high visual complexity decreases consumer size perceptions of a focal product through a serial mediation process in which high complexity pulls consumer attention away from the focal product. This shifted attention decreases processing fluency and leads consumers to perceptually minimize size to avoid information overload in the processing of a display. Even after ruling out potential influences of referent information (study 5) and alternative explanations of affective processing and perceived depth (study 4), these effects hold. The findings have implications for both theory and practice, shedding light on the relationship between size perceptions of a focal object and its environment.
