This study investigates the determinants of goodwill impairment decisions by firms applying IFRS based on a comprehensive sample of stock-listed firms from 21 countries. Multivariate logistical regression findings indicate that goodwill impairment incidence is negatively associated with economic performance, but also related to proxies for managerial and firm-level incentives.
This study provides evidence that nonbank institutional investors that participate in loan syndicates value inside information obtained through lending agreements with bellwether borrowers. The private information nonbank institutional investors obtain from lending relationships with bellwether firms can help identify trading opportunities in other public market securities. Thus, we predict and find that institutional investors compensate bellwether firms by charging a lower loan spread.
Cardiovascular disease has become a leading cause of death for patients with paraplegia. Acute myocardial infarction in patients with paraplegia has not been described in the literature. This study investigates clinical features, management strategies, and outcomes of these patients.
We empirically study the spatiotemporal location problem motivated by an online retailer that uses the Buy-Online-Pick-Up-In-Store fulfillment method. Customers pick up their orders from trucks parked at specific locations on specific days, and the retailer’s problem is to determine where and when these pickups occur. Customer demand is influenced by the convenience of pickup locations and days.
To enhance our understanding of emerging markets, we study a data set from the Casablanca stock exchange containing all the transaction records over a long span. The exchange was included in 1996 in the International Finance Corporation (IFC) data base roughly 3 years after important market reforms.
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.
This study provides evidence on whether investors value tax gross-up provisions for executives, and how the elimination of these provisions changes executive compensation. We examine the market response to tax gross-up eliminations and find investors react favorably to the removal of these provisions, suggesting that on average, investors perceived these agreements as a bad compensation practice that destroyed firm value.
This study examines the effects of mandatory IFRS adoption on accounting-based prediction models for CDS spreads for a sample of 357 firms in 16 IFRS-adopting countries. We do this by estimating accounting-based prediction models for CDS spreads separately for financial and non-financial firms before and after mandatory IFRS adoption. We find that mean and median absolute percentage prediction errors are larger for both financial and non-financial firms after mandatory IFRS adoption. We also estimate accounting-based prediction models for CDS spreads separately for financial and non-financial US firms before and after mandatory IFRS adoption to obtain prediction errors serve that as a benchmark.
We study the effect of senior manager oversight on inventors’ productivity. We use changes in travel times between inventors and their employer’s headquarters caused by flight time changes as sources of plausibly exogenous variation in manager oversight of inventors.
We study commitments to reduce emissions by firms subject to the European Union Emission Trading System (EU ETS), the world's largest cap-and-trade program. Commitments are associated with a drop in the number of carbon allowances surrendered, consistent with firms taking actions to reduce their emissions. However, firms subsequently increase their sales of allowances on the secondary market, transferring the right to pollute to others and potentially leaving aggregate emissions unchanged.
We study the problem of dynamically assigning jobs to workers with two key aspects: (i) workers gain or lose familiarity with jobs over time based on whether they are assigned or unassigned to the jobs, and (ii) the availability of workers and jobs is stochastic. This problem is motivated by applications in operating room management, where a fundamental challenge is maintaining familiarity across the workforce over time by accounting for heterogeneous worker learning rates and stochastic availability.
The case study "Electronic Financial-Advisor for Tech Savvy" (EFforTS, or Efforts) examines a Robo-Advisor start-up based in Raleigh, North Carolina, founded by tech-industry entrepreneurs. Efforts developed an algorithm-based online investment platform tailored for technology professionals, gaining attention through successful social media marketing.
Using a comprehensive and proprietary dataset on international private equity activity, we study the determinants of buyout investments across 61 countries and 19 industries over the period of 1990-2017. We find evidence that macroeconomic conditions, development of stock and credit markets, and the regulatory environment in a country are important drivers of international buyout capital flows.
This study uses passage of the Dodd-Frank Act as a setting to examine whether changes in legal liability exposure faced by credit rating agencies affect the number of financial statement information signals required before rating changes. For upgrades, we predict and find that the greater legal exposure after the Act incentivized rating agencies to require more information signals, i.e., a greater number of prior quarters in which upgrades were implied by financial statement information.
We coin the term credit market fluidity to describe the intensity of credit reallocation, whose properties and implications we study within the commercial loan market in France over the period 1998 through 2018. We base our analysis on credit register data and thus provide a more complete account of gross credit flows across and within bank loan portfolios.
Common wisdom suggests that when it comes to launching a startup, you need co-founders. But a new study finds that solo founders can in fact be successful — if they have the support of co-creators. Co-creators are individuals or organizations that play a critical role in helping a founder build their business, but without receiving the control or equity of a formal co-founder.
This study contributes to the growing strategic corporate social responsibility (CSR) literature by examining the intersection of acquisition studies and international expansion research and highlighting the unexplored impact of media coverage of CSR and corporate social irresponsibility (CSI) in shaping completion and duration outcomes of cross-border acquisitions.
To what extent do consumers boycott in response to corporate tax activities? Anecdotes suggest potential consumer backlash is a meaningful deterrent to corporate tax planning, and the tax literature has developed expectations that these boycotts happen. But empirical evidence on their existence and impact is limited. We undertake a comprehensive study to examine how consumers’ purchase behavior relates to corporate tax activities, triangulating across several designs, samples, and measures.
This paper studies how corporate tax cuts in developed countries affect economies in the developing world. We focus on one of the most prominent fiscal policies – the corporate income tax regime – and study a major U.K. tax cut as an exogenous shock to foreign investment in Africa.
We study the interaction of flexible capital utilization and depreciation for expected returns and investment of firms. Empirically, an investment strategy that buys (sells) equities with low (high) utilization rates earns 5% p.a.
