Prediction-driven Surge Planning With Applications in the Emergency Department

Optimizing emergency department (ED) nurse staffing decisions to balance the quality of service and staffing cost can be extremely challenging, especially when there is a high level of uncertainty in patient-demand. Increasing data availability and continuing advancements in predictive analytics provide an opportunity to mitigate demand-rate uncertainty by utilizing demand forecasts. In this work, we study a two-stage prediction framework that is synchronized with the base (made months in advance) and surge (made nearly real-time) staffing decisions in the ED. We quantify the benefit of the more expensive surge staffing. We also propose a near-optimal two-stage staffing policy that is straightforward to interpret and implement. Lastly, we develop a unified framework that combines parameter estimation, real-time demand forecasts, and staffing in the ED. High fidelity ED simulation experiments demonstrate that the proposed framework can reduce staffing costs by 8% – 17% while guaranteeing timely access to care.

Herding in Probabilistic Forecasts

Decision makers often ask experts to forecast a future state. Experts, however, can be biased. In the economics and psychology literature, one extensively studied behavioral bias is called herding. Under strong levels of herding, disclosure of public information may lower forecasting accuracy. This result, however, has been derived only for point forecasts. In this paper, we consider experts' probabilistic forecasts under herding, find a closed-form expression for the first two moments of a unique equilibrium forecast, and show that the experts report too similar locations and inflate the variance of their forecasts due to herding. Furthermore, we show that the negative externality of public information no longer holds. In addition to reacting to new information as expected, probabilistic forecasts contain more information about the experts' full beliefs and interpersonal structure. This facilitates model estimation. To this end, we consider a one-shot setting with one forecast per expert and show that our model is identifiable up to an infinite number of solutions based on point forecasts, but up to two solutions based on probabilistic forecasts. We then provide a Bayesian estimation procedure for these two solutions and apply it to economic forecasting data collected by the European Central Bank and the Federal Reserve Bank of Philadelphia. We find that, on average, the experts invest around 19% of their efforts into making similar forecasts. The level of herding shows an increasing trend from 1999 to 2007 but drops sharply during the financial crisis of 2007-2009, and then rises again until 2019.

Is your machine better than you? You may never know.

AI systems are increasingly demonstrating their capacity to make better predictions than human experts. Yet, recent empirical studies suggest that professionals sometimes doubt the quality of these systems, and as a result overrule machine-based prescriptions. This paper explores the extent to which a decision maker (DM) can properly assess whether a machine produces better recommendations. To that end, we analyze an elementary dynamic Bayesian framework, in which a machine performs repeated decision tasks under a DM’s supervision. The task consists in deciding whether to take an action or not. Crucially, the DM observes the accuracy of the machine’s prediction on the task only if she ultimately takes the action. As she observes the machine’s accuracy, the DM updates her belief about whether the machine’s predictions outperform her own. Depending on this belief, however, the DM sometimes overrides the machine, which affect her ability to assess it.

In this set-up, we characterize the evolution of the DM's belief and overruling decisions over time. We identify situations under which the DM’s belief oscillates forever, i.e., the DM always hesitates whether the machine is better. In this case, the DM never fully ignores the machine but regularly overrules it. We further find that the DM’s belief sometimes converges to a Bernoulli random variable, i.e., the DM ends up wrongly believing that the machine is better (or worse) with positive probability. We fully characterize the conditions under which these failures to learn occur. These results highlight some fundamental limitations in our ability to determine whether machines make better decision than experts. They further provide a novel explanation for why humans may collaborate with machines – even when one may actually outperform the other.

The Impact of Hallway Placement on Emergency Department Quality of Care

Emergency Department (ED) crowding is a constant and relentless operational challenge that hospitals face across the country. With the intention to make timely care accessible to more patients, the emergency department often takes advantage of an additional source of capacity within the ED — the hallways. In this study, we investigate and quantify the impact of patient placement in the hallway on ED patient flow and quality measures through a quasi-experimental research design. In addition, we conduct heterogeneous analysis across ED operational settings to understand whether hallway placement uniformly backfires across utilization levels.

Frustration-Based Promotions: Field Experiments in Ride-Sharing

The service industry has become increasingly competitive. One of the main drivers for increasing profits and market share is service quality. When consumers encounter a bad experience, or a frustration, they may be tempted to stop using the service. In collaboration with the ride-sharing platform Via, our goal is to understand the benefits of proactively compensating customers who have experienced a frustration. Motivated by historical data, we consider two types of frustrations: long waiting times and long travel times. We design and run three field experiments to investigate how different types of compensation affect the engagement of riders who experienced a frustration. We find that sending proactive compensation to frustrated riders (i) is profitable and boosts their engagement behavior, (ii) works well for long waiting times but not for long travel times, (iii) seems more effective than sending the same offer to nonfrustrated riders, and (iv) has an impact moderated by past usage frequency. We also observe that the best strategy is to send credit for future usage (as opposed to waiving the charge or sending an apologetic message).

Redesigning Sample Transportation in Malawi Through Improved Data Sharing and Daily Route Optimization

Healthcare systems in resource-limited settings rely on diagnostic networks in which medical samples (e.g. blood, sputum) and results need to be transported between geographically dispersed healthcare facilities and centralized laboratories. Due to lack of updated information, existing sample transportation (ST) systems typically operate fixed schedules which do not account for demand variability. We present an innovative approach for timely collection of information on transportation demand (samples and results) using low-cost technology based on feature phones and integrate it with a novel Multi-Stage version of the Dynamic Multi-Period Vehicle Routing Problem to generate daily routes in response to this updated information. We design the Optimized Sample Transportation (OST) system which comprises two components: a novel data sharing platform to monitor incoming sample volumes at healthcare facilities, and an optimization based solution approach to the problem of routing and scheduling courier trips in a multi-stage transportation system. We implement OST in collaboration with Riders For Health, who operate the national ST system in Malawi. Our solution approach performs well in a range of numerical experiments. Based on analysis of implementation data describing over 20,000 samples and results transported during July-October 2019, we show that the implementation of OST routes reduced average ST delays in three districts of Malawi by approximately 25%. In addition, the proportion of unnecessary trips by ST couriers decreased by 55%. Results from our implementation demonstrate the practical feasibility of our novel approach for improving centralized ST operations in Malawi and its broader applicability to other resource-limited settings, particularly in sub-Saharan Africa.

Estimating the Impact of Climate Change: An Empirical Analysis of Smart Thermostat Data

Using a rich micro-level dataset, we empirically analyze smart thermostat data to understand the relationship between households' thermostat settings and their ambient environment. Using a unique methodology combining Dynamic Linear Models, random effects, and Bayesian Statistics, we develop models for short and long-term behavior. Using weather simulations we estimate the impact of climate change, and identify key patterns in household actions that drive large differences in consumption.

Control of Nonlinear Opinion Dynamics in Social Networks

Our goal is to persuade large-scale social networks. Persuasion here means using agents to optimize a function of the opinions in the network. Many of the opinion dynamics models which capture realistic behaviors are nonlinear. This nonlinearity makes it difficult to learn a policy that optimizes the opinion function. In this study, we provide a mathematical model that describes nonlinear opinion dynamics and learn a policy to maximize the mean opinion using optimal control theory. Our control policy not only achieves the optimal objective in certain networks, but it is interpretable, scalable, and efficient for human-like agents in large-scale social networks.

Doing Well by Doing Good: Improving Store Performance with Responsible Scheduling Practices at the Gap, Inc.

We estimate the causal effects of responsible scheduling practices on store financial performance at the US retailer Gap, Inc. The randomized field experiment evaluated a multi-component intervention designed to improve dimensions of work schedules – consistency, predictability, adequacy, and employee control – shown to foster employee well-being. The experiment was conducted in 28 stores in the San Francisco and Chicago metropolitan areas for nine months between November 2015 and August 2016. Intent-to-treat (ITT) analyses indicate that implementing responsible scheduling practices increased store productivity by 5.1%, a result of increasing sales (by 3.3%) while also decreasing labor (by 1.8%). Drawing on qualitative interviews with managers and quantitative analyses of employee shift-level data, we offer evidence that the intervention improved financial performance through improved store execution. Our experiment provides evidence that responsible scheduling practices that take worker well-being into account can enhance store productivity by motivating additional employee effort and reducing barriers to employees adhering to the scheduled labor plan.

Improving Match Rates in Dating Markets Through Assortment Optimization

Motivated by our collaboration with an online dating company, we study how a platform should dynamically select the set of potential partners to show to each user in each period in order to maximize the expected number of matches in a time horizon, where a match is formed only after two users like each other, possibly in different periods. Our work combines several methodologies. We model the platform's problem as a dynamic optimization problem. We use econometric tools and exploit a change in the company's algorithm in order to estimate the users' preferences as well as other parameters of interest. We find that the number of matches obtained in the recent past has a negative effect on the like behavior of users. We propose a family of heuristics to solve the platform's problem that leverage these data findings, and use simulations to assess their benefits. Two field experiments show that our algorithm yields at least 27% more matches relative to our industry partner's algorithm. Overall, our results highlight the importance of correctly accounting for the preferences, behavior, and activity metrics of users on both ends of a transaction to improve the operational efficiency of matching platforms.

To What Extent Do Workers’ Preferences Matter?

Our research investigates how preference satisfaction, particularly intrinsic values such as psychological comfort, can improve a worker’s service efficiency and quality. Examining a comprehensive dataset linking surgeons’ performances to their preferences for operating rooms, we not only confirm the significant role of intrinsic values in driving workers’ service efficiency and quality but also quantify the preference satisfaction effect as large enough to serve as a new managerial lever for firms. However, we also find that compared to workers without preferences, workers with preferences perform better if satisfied, but worse if unsatisfied. This suggests that firms should consider the cultivation of workers’ preferences only if their systems can satisfy their workers. Furthermore, our second-order analysis suggests that in a restricted system, managers should prioritize satisfying workers with heavy workloads or complex tasks to achieve the greatest improvement. Finally, we update the surgery scheduling framework by incorporating surgeons’ preferences. Our counterfactual analysis demonstrates that preference satisfaction can achieve huge benefits in operation cost saving and patient welfare improvement at little expense. For the operations in our sample, we find satisfying surgeons’ preferences can reduce healthcare costs by over 4 million dollars, not to mention the potential for significant improvement in patients’ and surgeons’ welfare.
