The relation between equity incentives and misreporting: The role of risk-taking incentives

Prior research argues that a manager whose wealth is more sensitive to changes in the firm?s stock price has a greater incentive to misreport. However, if the manager is risk-averse and misreporting increases both equity values and equity risk, the sensitivity of the manager?s wealth to changes in stock price (portfolio delta) will have two countervailing incentive effects: a positive “reward effect” and a negative “risk effect.” In contrast, the sensitivity of the manager?s wealth to changes in risk (portfolio vega) will have an unambiguously positive incentive effect. We show that jointly considering the incentive effects of both portfolio delta and portfolio vega substantially alters inferences reported in prior literature. Using both regression and matching designs, and measuring misreporting using discretionary accruals, restatements, and enforcement actions, we find strong evidence of a positive relation between vega and misreporting and that the incentives provided by vega subsume those of delta. Collectively, our results suggest that equity portfolios provide managers with incentives to misreport when they make managers less averse to equity risk.     

The timing of pay

There exists large and persistent variation in not only how, but when employees are paid, a fact unexplained by existing theory. This paper develops a simple model of optimal pay timing for firms. When workers have self-control problems, they under-save and experience volatile consumption between paychecks. Thus, pay whose delivery matches the timing of workers' consumption needs will reduce wage costs. The model also explains why pay timing should be regulated (as it is in practice): although the worker benefits from a timing profile that smoothes her consumption, her lack of self-control induces her to attempt to undo the arrangement, either by renegotiating with her employer or by taking out payday loans. Regulation of pay timing and consumer borrowing is required to counter these efforts, helping the worker help herself.     

Estimating network economies in retail chains: a revealed preference approach

We measure the effects of chain economies, business stealing, and heterogeneous firms’ comparative advantages in the discount retail industry. Traditional entry models are ill suited for this high‐dimensional problem of strategic interaction. Building upon recently developed profit inequality techniques, our model admits any number of potential rivals and stores per location, an endogenous distribution network, and unobserved (to the econometrician) location attributes that may cause firms to cluster their stores. In an application, we find that Wal‐Mart benefits most from local chain economies, whereas Target shows a greater ability to respond to rival competition. Kmart exhibits neither of these strengths. We explore these results with counterfactual simulations highlighting these offsetting effects and find that local chain economies play an important role in securing Wal‐Mart's industry leader status.     

The sources of innovations – looking beyond technological opportunities*

The concept ‘technological opportunity’ has been coined to capture the vitality of the underlying sciences and technologies as the sources of technical progress that firms draw upon during innovation. Nonetheless, less attention has been paid to the fact that the commercialisation of technical progress through innovations also depends on the ability to assimilate a range of other sources of innovations, related less to the sciences and technologies and more to characteristics of the market and broader environment in which firms innovate. This paper focuses on the sectoral diversity in such sources, and on the ways in which they are assimilated and turned into commercialised innovations. The paper contributes to the extant literature by drawing on a unique survey data on Finnish innovations. The results both confirm and also challenge, and further elaborate on certain ‘stylised facts’ on the relationships between technological opportunities and the sources of innovation across sectors.     

The Organizational Impact of Business Model Innovation: Assessing the Person-Organization Fit

Studies on business model innovation (BMI) have largely focused on firm performance, neglecting outcomes of BMI beyond financial performance indicators. Research lacks empirical findings from the internal organizational dynamics following the inherent transformation process induced by BMI. Rooting our analysis in configuration theory, the purpose of this paper is to shed light on the organizational impact of BMI. We employ the person-organization fit concept and assess (unintentional) changes in the fit relationship subsequent to BMI. Our findings suggest that incremental BMI enhances fit whereas radical BMI decreases it. We further discuss the theoretical and practical implications of our study.     

The effects of age,experience and managers upon baseball performance

As workers age, they acquire valuable experience even while their physical abilities eventually decline. Bosses/managers have the potential to alter the complex relationships between experience and declining physical abilities for better, or for worse. We examine the performances of 39,698 Major League baseball players in the 20th century and find that: (1) hitting performance peaks at age 30, base stealing at 27, and pitching at 34; (2) except for pitching, even experienced managers usually have little influence on player performance, or that influence is negative. In general, managers and coaches play limited roles in occupations where natural ability trumps other factors.     

Bayesian estimation approaches to first-price auctions

This paper considers Bayesian estimation strategies for first-price auctions within the independent private value paradigm. We develop an ‘optimization’ error approach that allows for estimation of values assuming that observed bids differ from optimal bids. We further augment this approach by allowing systematic over or underbidding by bidders using ideas from the stochastic frontier literature. We perform a simulation study to showcase the appeal of the method and apply the techniques to timber auction data collected in British Columbia. Our results suggest that significant underbidding is present in the timber auctions.     

The employer's case for health management

Employers' past solutions to rising health benefit costs--adopting managed care strategies, cost shifting to employees and reducing benefits-are no longer effectively controlling costs and are depressing the value of health benefits for employee recruitment and retention. An alternative strategy is to implement health management approaches that improve the health status of employees. These programs reduce medical costs and have a documented positive impact on workers' compensation, disability costs, absenteeism and productivity. Further, this approach is complementary to health care consumerism as a strategy for health improvement and benefit cost reduction and results in improved employee health, outlook and satisfaction.     

Universal telecommunication service: A world perspective

Worldwide telecommunications demand is estimated in models for business and residential mainline telephone, and for mobile telephone service using separate models for developed and developing countries for the period 1996–2001. We test for cross-price elasticities between mainline and mobile service and find that the results are generally suggestive of current complementary relationships. We find residential monthly price elasticity to be no different than zero for a sample of developing countries, but the connection elasticity is statistically significant. Mobile monthly service elasticity is much larger than those for mainline service, suggesting that universal service in developing countries might be promoted more effectively with subsidies for mobile service. Income elasticities for the residential model are modest while the mobile service model income elasticity for developing countries is much higher. Expanding markets, income growth and enhanced education may be the ultimate universal service promoters.
