Multicultural experiences – such as living, traveling, or working abroad – can have many psychological benefits, including decreasing intergroup bias. However, unlike the intergroup contact literature, research on multicultural experiences has yet to examine whether the valence of these experiences may moderate such outcomes. So, could multicultural experiences actually increase intergroup bias? Five studies reveal that multicultural experiences increase (rather than decrease) intergroup bias when those experiences are negative (rather than positive).
Long depicted as a global melting pot, the United States is home to a collection of sharply divergent geographies, regions and cultures. An overlooked measure of our diversity, however, is economic. While national statistics tell a story of averages, they fail to account for the true drivers of economic expansion and contraction. It is only upon examining America’s microeconomies – our cities, towns, suburbs and rural communities – that we can begin to appreciate the myriad and complex determinants of broader U.S., and sometimes even global, economic trends.
Productivity is the single most important determinant of a society’s standard of living. But how can you gauge it, and why does it matter? In this second report from the American Growth Project, we examine the productivity levels of the 50 largest microeconomies in the United States along with how those productivity levels have shifted during the last 15 years.
To date, our work on the American Growth Project has focused on the United States’ most populous urban areas. Our previous analyses of growth and productivity in the 50 largest Extended Metropolitan Areas (EMAs) have served to illustrate the tremendous amount of economic diversity to be found within the United States, revealing stark variations in economic trends, major industries and migration patterns in the country’s largest cities. We turn now to the task of measuring and analyzing economic activity in the next largest set of EMAs: the top 100 midsize cities.
The paper uses structured machine learning regressions for nowcasting with panel data consisting of series sampled at different frequencies. Motivated by the problem of predicting corporate earnings for a large cross-section of firms with macroeconomic, financial, and news time series sampled at different frequencies, we focus on the sparse-group LASSO regularization which can take advantage of the mixed-frequency time series panel data structures.
It is common wisdom that practice makes perfect. And, in fact, we find evidence that when given a choice between practicing a task and reflecting on their previously accumulated practice, most people opt for the former. We argue in this paper that this preference is misinformed. Using evidence gathered in ten experimental studies (N = 4,340) conducted across different environments, geographies, and populations, we provide a rich understanding of the conditions under which the marginal benefit of reflecting on previously accumulated experience is superior to the marginal benefit of accumulating additional experience.
Although the level of power held by the marketing department can determine key organizational outcomes, including firm performance, we show that this power has been decreasing since 2007. To address this apparent disconnect, we propose that the board of directors is a critical but overlooked antecedent of marketing department power. In particular, we demonstrate that directors’ exposure through board service at other firms (i.e., board-interlocked firms) affects the marketing department’s power in the firms on whose boards they also serve (i.e., focal firms).
In business markets, marketing and sales functions often conflict over customer acquisition. Marketers are seen to complain that sales representatives disregard the leads they generate, while sales representatives question the revenue potential of these leads. How should firms resolve such conflicts? We investigate these questions using relatively novel sequential principal-agent models with risk averse agents where asymmetry of information exists regarding leads’ revenue potentials.
We examine the consequences of corporate tax enforcement for business activity. Employing two different empirical approaches—a regional design and a firm-level design—we document that corporate tax enforcement is negatively associated with business activity. This association is economically significant and is robust to tests that mitigate concerns regarding endogeneity and measurement.
Lack of co-movement between consumption growth differentials and real exchange rates is a traditional indicator of a disconnect of foreign exchange markets from economic fundamentals (Backus-Smith 1993 anomaly). We present novel evidence for the (dis)connect between the volatilities, as opposed to the levels, of these variables. The volatility correlations are below one, but they are larger than the level correlations. In the cross-section of countries, the volatility disconnect weakens for countries with low amount of expected growth risk and high amount of volatility risk. We provide an explanation of our empirical findings based on international risk-sharing of both expected growth and volatility news shocks.
About 27% of diabetics also suffer from depression, and the presence of co-morbid depression could increase the cost of care for diabetes by up to 100%. Several randomized clinical trials have demonstrated that physical and mental health are more likely to improve for diabetes patients suffering from depression when regular treatment for depression is provided in a primary care setting (called Collaborative Care). An important operational lever in managing Collaborative Care is the allocation of the care manager's time to enrolled patients based on their requirements, which in turn influences the revenue, costs, and patient health outcomes. We present a mathematical modeling approach that determines the optimal allocation of care manager's time and quantifies the costs and benefits of Collaborative Care.
This study finds that voluntary non-earnings disclosure substitutes for redacted proprietary contract information. When firms redact contract information, they provide more voluntary disclosures and have higher information uncertainty and asymmetry. Although firms provide both voluntary non-earnings and earnings disclosures when they redact contract information, only non-earnings disclosures included in Forms 8-K mitigate the higher information uncertainty and asymmetry associated with redaction. These findings suggest earnings disclosures may not be specific enough to substitute for redacted contract information and contrast with the presumption in related research that firms provide earnings disclosures to substitute for withheld proprietary information.
The rapid growth in the adoption of mobile payments has already begun to reshape bank payment practices. Utilizing a unique data set from a leading bank in Asia that records credit card transactions of its customers before and after the launch of Alipay mobile payment, the largest mobile payment platform in the world, this study aims to understand the impact of mobile payment adoption on bank customer credit card activities and the change of this impact after the mobile payment expansion.
The executive labor market (ELM) is a topic of interest that spans several academic fields. The outcomes of the ELM, including executive selection, succession, and compensation, are important considerations as they influence executive decision making and other organizational outcomes. Yet, a comprehensive framework of ELM dynamics currently does not exist. To address this shortcoming, we reviewed the existing literature using five fundamental questions: (1) What executive jobs are available? (2) Who is available to fill executive jobs, and what is valued on the ELM? (3) Who signals interest in the executive jobs? (4) Who gets offered/accepts the executive job, and what is the agreed-upon compensation? (5) How do status and social capital influence ELM outcomes? By answering these questions, our review provides a framework for integrating existing research on the ELM while suggesting avenues for future research.
The 2022 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel was awarded to Ben S. Bernanke, Douglas W. Diamond, and Philip H. Dybvig “for research on banks and financial crises”. This article surveys the contributions of the three laureates and discusses how their insights have changed the way that academics and policymakers understand banks and their roles in financial crises.
We review the accounting literature on innovation, focusing on the attributes of innovation that collectively make it unique from other resources: novelty, nonrivalry, and partial excludability. These unique attributes help innovation drive economic growth but create information-based challenges that accounting researchers are well-suited to address. We discuss the definition and measurement of innovation, then review the accounting literatures on the disclosure, management, financial reporting, taxation, and contracting and financing of innovation. For each of these literatures we identify challenges and opportunities for future research.
Health care costs in the United States make up a larger proportion of gross domestic product (GDP) than in any other developed country and continue to rise. We examine whether the use of consistent metrics in costing information systems across hospitals provides one avenue to reduce these costs. We refer to such consistency as “costing information consistency” or CIC and empirically measure it by identifying whether hospitals in a multihospital system share the same costing system vendor. Using M&A activity among vendors as an instrument for exogenous changes in hospital CIC, we find that CIC is associated with a 13.3% reduction in operating expenses, suggesting that increased cost comparability from CIC helps hospitals identify ways to reduce operating expenses by identifying clinical and administrative best practices.
Co-brands are strategically advantageous partnerships which can also involve risk. For example, Papa John’s gained access to the largest television audience in the US by sponsoring the National Football League (NFL), but later blamed stagnant sales on how the NFL’s handled players’ well-publicized protests of inequitable policing. What implications did Papa John’s prioritization of sales over fairness have for NFL consumption? To answer this question, the current research tests for changes in Sunday watch party rituals (SWPR), when U.S. consumers gather to socialize while watching live NFL games.
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.
General Partners (GPs) in private equity face a trade-off between focusing their skills and effort on fewer investments to earn higher returns, or investing more broadly to reduce risk through diversification. Using a novel, deal-level dataset of 5,925 global investments from 1999 to 2016, we show that these portfolio considerations are important for understanding fund-level private equity returns.
