Title: "Delta Coverage: The Analytics Journey to Implement a Novel Nurse Deployment Solution" Co-authored with Pengyi Shi.

Synopsis: The COVID-19 pandemic has created new opportunities to develop and deploy high-impact analytics to combat severe resource shortages and a rapidly evolving healthcare ecosystem. Nursing organizations suffered both during and in the aftermath of the pandemic from excess demand for and diminishing supply of nurses. The nurse shortage was caused in part by nurses leaving the profession as well as nurses leaving their permanent jobs to take lucrative travel nursing contracts. With limited ability to replace nurses, hospitals struggle to maintain adequate staffing amidst the massive spike in workforce variability.

In January 2021, we embarked on a journey in partnership with Indiana University (IU) Health System, the largest health system in Indiana with 16 hospitals, to jointly develop a suite of advanced data and decision analytics to support a new internal travel nursing program at IU Health. In January 2021, we launched an academia-industry venture to develop and deploy a data-driven solution to support this systemwide program, which was branded the Delta Coverage program. Delta Coverage expands the floating capacity to their entire network.   Effective implementation of this program requires an analytics tool integrating forecasting and optimization to improve quality of care while respecting the working conditions of the nursing staff. To provide 1-2 weeks advanced notice of travel, we developed a novel machine-learning-based occupancy forecasting model that accounts for different levels of patient acuity. Using distributional information from the forecast, we generate workload scenarios for the network along with a probability measure over the scenarios. These scenarios are fed into a two-stage stochastic program where the decision variables mimic the timing and type of decisions being made in practice.

The decision support tool was implemented in October 2020 as a Microsoft Power BI application that recommends how many nurses to put on-call 1-2 weeks in advance and how many on-call nurses to deploy to a remote hospital, with the option to cancel some of the planned travel if it is found not to be needed closer to the time of deployment. We logged the performance of the recommendations from October 2021 to March of 2022 as a proof of value, with the tool running each day in real time. Analysis indicates system-wide improvements in all metrics: with reductions of 5% understaffing3% misallocation of resource nurses, and 1% overstaffing. Further benefits include a narrowing of the staff to demand fluctuation, with a reduction in the third quartile of understaffing of 32% and in overall understaffing variance of 4%.  The estimated savings is $100K in overstaffing, $55K in misallocated resources, and $150K in overtime. The annualized savings of over $900K.

Title: "Uncertainty: How to Understand and Deal With It"

Synopsis: In supply chain management, uncertainty (existing in both demand and supply), and the associated cost caused have been paid more and more attention by industrial practitioners. Particularly, in Covid19 pandemic, the shortages of goods and the major fluctuations in demand have caused significant losses in the global supply chains. In this seminar, I will mainly introduce the following research topics on uncertainty I have recently conducted:

  1. Understand uncertainty. Uncertainty in demand or supply may be due to their uncertainty nature. For example, the consumers’ uncertain preference or other uncontrollable factors such as pandemic, and the uncertain yield rate of supply due to the unstable quality of the raw materials etc. The other source of uncertainty is information asymmetry among supply chain members, as firms need to make strategy based on its limited information about the other members in the supply chain.
    1. In the case of uncertainty nature, how does the uncertainty influence the operational decisions in a supply chain?
    2. How much loss in profit is caused by the information asymmetry?
       
  2. Deal with uncertainty.
    1. In the case of uncertain nature, firms can make efforts to reduce the uncertainty in either demand or supply. How efficient are the uncertainty reduction efforts?
    2. In the case of information asymmetry, is it more beneficial for the less-informed firm to trust the information revealed by the more-informed firm, or achieve the true information from the more-informed firm through information screening?

Title: "Corporate M&As and labor market concentration: Efficiency gains or power grabs?" Co-authored with David Cicero (Auburn University) and Mo Shen (Auburn University).

Synopsis: There have been growing concerns among economists and policymakers that labor markets in the United States are getting increasingly concentrated. Motivated by this finding, we investigate if the increase in labor market concentration due to a merger between two firms leads to value creation for the merging firms. We also evaluate whether deals are motivated either by firms’ efforts to increase their labor market power vis-à-vis the employees, or to realize labor efficiencies by merging entities with overlapping labor markets. Using establishment-level employment data, we create a novel measure of the change in labor market concentration due to a merger. We find that an increase in this measure predicts merger firm pair formation. Furthermore, the merger-related increase in labor market concentration is positively related to the combined wealth effect to the merging firms, negatively related to the wealth effect of rival firms, and positively related to the wealth effects of supplier and customer firms. We also document a decrease in total employment and an increase in IT spending in establishments of the merging firms that experience a greater increase in labor market concentration. Overall, our evidence suggests that increased labor market concentration in mergers enables efficiency enhancing post-merger restructuring rather than enhancement of employer market power.

Title: "Seeking a Friend and an Ally." Co-authored with Steven Hyde, Eric Bachura, and Megan Thornton-Lugo.

Synopsis: It is widely known in other micro fields such as organizational behavior and psychology that motivation is an important predictor of behavior. Yet the alliance and Upper Echelons literature have largely overlooked this important antecedent. A deeper understanding of a CEO’s motivations can illuminate why a firm may engage in higher levels of alliance activity while another firm may not. In this study, we explore how CEO needs—a manifestation of internal motivation—may impact alliance behavior. The results of our study demonstrate that the motivations of CEOs – namely their need for affiliation– have a non-linear relationship with alliance activity. More specifically, the results suggest an initial positive relationship between the need for affiliation and alliance activity. However, at high levels of affiliation, the CEO’s concern for harmony with their board becomes more important, resulting in lower alliance activity.

Title: "Management Forecast Precision and the Commonality of Analyst Information." Co-authored with Orie Barron, Lyndon Orton, and David Yu, all from Penn State University.

Synopsis: In this study, we examine the relationship between managers’ earnings forecast precision and changes in the characteristics of analysts’ information as reflected in their forecast errors. We argue that more precise / specific management forecasts provide analysts with information of lower cost than their own private efforts. Thus, as management forecast specificity increases, analysts are incentivized to substitute managements’ forecast for their own, increasing the commonality among analysts’ forecasts. Consistent with this, we find the change in consensus, a measure of commonality, is increasing in the specificity of managements’ forecast. This finding is of interest because it identifies a mechanism through which management may influence the degree to which analysts rely on similar information. In addition, we find evidence that analyst forecast accuracy is declining in the specificity of managements’ forecast. By increasing the specificity of the forecast, management can level the playing field among market participants but at a cost of decreased accuracy of the mean forecast.
