We investigate the stock market reactions to the announcements of Black CEO and top management team (TMT) appointments in light of two conflicting studies that advance competing and opposite theories.
This paper presents the development, validation, and implementation of a data-driven optimization model designed to dynamically plan the assignment of anesthesiologists across multiple hospital locations within a large multi-specialty healthcare system. We formulate the problem as a multi-stage robust mixed-integer program incorporating on-call flexibility to address demand uncertainty. The optimized dynamic staffing plan has been successfully implemented in the University of Pittsburgh Medical Center healthcare system, leading to estimated annual cost savings of 12\% compared to current practice, or about \$800,000 annually.
Failing to consider neurodiversity when trying to create truly diverse and inclusive workplaces has crucial implications for productivity and general life satisfaction. Organizations should consider these three points of action to improve their work environments and cultures.
With the explosion of Internet users, growing from 360 million (5.9 % of the world’s population) in 2000 to 3.4 billion (46.4 %) in 2016, the digital space is reshaping how organizations go global with their brands. Any chapter written about digital branding strategies runs the risk of obsolescence before it hits the printer. Specific digital platforms and tools for global brand building change rapidly over time.
This paper analyzes factors that shape the technological capabilities of individual U.S. states and European countries, which are arguably comparable policy units. The analysis demonstrates convergence in technological capabilities from 2000 to 2007.
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.
Networks of serial entrepreneurs, investors, and their affiliated companies play a critical role in driving entrepreneurial behavior, investor focus, and innovation hot spots within specific industry sectors and are critical for shaping the character of robust regional economies.
Governments often subsidize startups with the goal of spurring entrepreneurship using tax incentives. Exploiting the staggered implementation of angel investor tax credits in 31 U.S. states from 1988 to 2018, we find that these programs increase the number of angel investments and average investment size.
Despite having the deepest and most diverse capital markets in the world, the United States still struggles to provide sufficient capital to many small businesses outside of major commercial centers as well as to women-owned and minority-owned businesses regardless of size or location. This paper reviews the academic literature and provides an analysis of some recent data to gain understanding of the causes of these gaps as well as the solutions for filling the gaps. Results indicate that the Small Business Administration’s SBIC program is an effective mechanism for providing capital to underserved geographies as well as to businesses owned by women and underrepresented minorities.
This paper provides evidence on the determinants and economic outcomes of updates of accounting systems (AS) over a 24-year time-span in a large sample of U.S. hospitals.
We investigate the number of and reasons for errors and questionable judgments that sell-side equity analysts make in constructing and executing discounted cash flow (DCF) equity valuation models. For a sample of 120 DCF models detailed in reports issued by U.S. brokers in 2012 and 2013, we estimate that analysts make a median of three theory-related and/or execution errors and four questionable economic judgments per DCF.
In this paper, we develop a sociodemographic profile of the most vulnerable African American older adult households. To do so, we draw data from the 2011–15 American Community Survey, which contains linked housing and person records for a 5 percent sample of U.S. population. This dataset literally allows us to peer inside of African American older adult households and in the process identify the major barriers or obstacles to aging in place.
Our analysis of how banks’ responses to asset price changes can result in procyclical leverage reveals that, for banks with a binding regulatory leverage constraint, absent differences in regulatory risk weights across assets, procyclical leverage does not occur. For banks without a binding constraint, fair value and bank regulation both can contribute to procyclical leverage. Empirical findings based on a large sample of U.S. commercial banks reveal that bank regulation explains procyclical leverage for banks relatively close to the regulatory leverage constraint and contributes to procyclical leverage for those that are not. We also show that fair value accounting does not contribute to procyclical leverage.
Little is known about how TMT members affect a founder-led firm’s performance later in a firm’s life. Using novel methods and a sample of over 2,000 firms, we find that although team structure has a significant impact on the performance of non-founder-led firms (consistent with past literature), it has little to no effect on the operating performance of founder-led firms, suggesting that founder CEOs may exert too much control.
We examine the effect of higher wages on firm performance during the 2008 financial crisis. To identify variation in wages, we rely on heterogeneity in the timing of long-term wage agreements for a sample of UK firms. We instrument for firms signing long-term agreements overlapping with the crisis by the presence of a contract signed in 2006 or earlier and expiring before September 2008.
I investigate the exit outcomes of start-ups backed by government VCs (GVCs) and private VCs (PVCs), using a sample of 8,106 start-ups in China funded by VCs between 1991 and 2013 and exit information updated in 2018. I find that start-ups backed by GVCs are less likely to exit through domestic Initial Public Offerings (IPOs), oversea IPOs, and M&As. GVC backed start-ups are also less likely to list on the intermediate public market before companies go to IPOs.
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 apply advances in analysis of mix frequency and sparse data to estimate “unsmoothed” private equity (PE) Net Asset Values (NAVs) at the weekly frequency for individual funds. Using simulations and a large sample of buyout and venture funds, we show that our method yields superior estimates of fund asset values than a simple approach based on comparable public asset and as-reported NAVs.
We find that equity loan fees are the best predictor of cross-sectional returns. When compared to 102 other anomalies, the loan fee anomaly has the highest monthly long-short return (1.17%), has the highest monthly Sharpe Ratio (0.40), and unlike other anomalies, exhibits strong persistence throughout the sample.
