The Store Is Dead—Long Live the Store.
In this article, we pursue two interconnected themes: the expansion of online-first retailers into offline stores that serve the purpose of “supercharging” customer value, and the transformation of the stores of offline-first retailers from fulfillment-dominant centers into experience-dominant centers, which simultaneously reduce store size and inventory while improving the customer experience. In doing so, we explain how offline-first retailers can benefit from mimicking the showroom concepts started by online-first retailers and why online-first retailers can benefit from opening more traditional stores.

Offline Showrooms in Omni-channel Retail: Demand and Operational Benefits
Winner of the 2014 POMS Applied Research Challenge. Workshop on Information Systems Economics Overall Best Paper Award 2014
Omnichannel environments where customers shop online and offline at the same retailer are ubiquitous, and are deployed by online-first and traditional retailers alike. We focus on the relatively understudied domain of online-first retailers and the engagement of a key omnichannel tactic; specifically, introduction of showrooms (physical locations where customers can view and try products) in combination with online fulfillment that uses centralized inventory management. We ask whether, and if so, how, showrooms benefit the two most basic retail objectives: demand generation and operational efficiency. Using quasi-experimental data on showroom openings by WarbyParker.com, the leading and iconic online-first eyewear retailer, we find that showrooms: (1) increase demand overall and in the online channel as well; (2) generate operational spilloversto the other channels by attracting customers who, on average, have a higher cost-to-serve; (3) improve overall operational efficiency by increasing conversion in a sampling channel and by decreasing returns; and (4) amplify these demand and operational benefits in dealing with customers who have the most acute need for the firm’s products. Moreover, the effects we document strengthen with time as showrooms contribute not only to brand awareness but also to what we term channel awareness as well. We conclude by elaborating the underlying customer dynamics driving our findings and by offering implications for how online-first retailers might deploy omnichannel tactics.

The Value of Fit Information in Online Retail: Evidence from a Randomized Field Experiment
Santiago Gallino and Antonio Moreno
Online channels generate frictions when selling products with nondigital attributes, such as apparel. Customers may be reluctant to purchase products they have not been able to try on, and those customers who do purchase may return products when they do not fit as expected. Virtual fitting-room technologies provide information about how a product fits a particular customer and promise to mitigate some of the frictions the information gap generates in the retailers’ supply chains. By implementing a series of randomized field experiments, we study the value of virtual fit information in online retail. In our experiments, customers are randomly assigned to a treatment condition where virtual fit information is available or to a control condition where virtual fit information is not available. Our results show that offering virtual fit information increases conversion rates and order value and reduces fulfillment costs arising from returns and home try-on behavior, that is, customers ordering multiple sizes of the same product. We explore mechanisms through which providing virtual fit information helps customers and retailers. We argue that the virtual fitting tool creates spillovers even to products that are not available for virtual try-on, increases loyalty, helps customers better parse their choice sets, and reduces uncertainty by providing size recommendation.

Channel Integration, Sales Dispersion, and Inventory Management
Santiago Gallino, Antonio Moreno and Ioannis Stamatopoulos
We study the effects of the introduction of cross-channel functionalities on the overall sales dispersion of retailers and the implications of these effects for inventory management. To do that, we analyze data from a leading U.S. retailer who introduced a “ship-to-store” (STS) functionality that allows customers to ship products to their local store free of charge when those products are not available in their local store. Based on the fact that stores prioritize carrying products for which local demand is high, we test the hypothesis that introducing the STS functionality increased the retailer’s overall sales dispersion. We find that, on average, the contribution of the 90% lowest-selling products to total sales increased by 0.75 percentage points, increasing sales dispersion. Calibrating conventional inventory-ordering models, we show that to respond optimally to the observed increase in dispersion, the retailer would need to increase its cycle and safety inventories by approximately 2.7%. Our paper points out the effect of an increasingly important retail phenomenon (channel integration) on a key factor for inventory management (sales dispersion).

The Operational Value of Social Media Information
Ruomeng Cui, Santiago Gallino, Antonio Moreno and Dennis J. Zhang
While the value of using social media information has been established in multiple business contexts, the field of operations and supply chain management have not yet explored the possibilities it offers in improving firms' operational decisions. This study attempts to do that by empirically studying whether using publicly available social media information can improve the accuracy of daily sales forecasts. We collaborated with an online apparel retailer to assemble a dataset that combines (1) detailed internal operational information, including data on sales, advertising, and promotions, as well as (2) publicly available social media information obtained from Facebook. We implement a variety of machine learning methods to forecast daily sales. We find that using social media information results in statistically significant improvements in the out-of-sample accuracy of the forecasts, with relative improvements ranging from 12.85% to 23.23% over different forecast horizons. We also demonstrate that nonlinear boosting models with feature selection, such as random forests, perform significantly better than traditional linear models. The best-performing method (random forest) yields an out-of-sample mean absolute percentage error (MAPE) of 7.21% when not using social media information and 5.73% when using social media information is used. In both cases, this significantly improves the accuracy of the company's internal forecasts (a MAPE of 11.97%). Combining these empirical results, we provide recommendations for forecasting sales in general as well as with social media information.

The Effects of Product Line Breadth: Evidence from the Automotive Industry
Antonio Moreno and Christian Terwiesch
Using a detailed data set from the U.S. automotive industry, we enrich the existing literature on product line breadth with new results that highlight previously unexplored operational aspects of its benefits and costs. We find that expanding product line breadth has a significant effect on increasing mismatch costs arising from the increased demand uncertainty associated with product proliferation. These mismatch costs are manifested through additional discounts and inventories. The effect of product line breadth on mismatch costs is comparable in magnitude to the effect on production costs, suggesting that the operational benefits of inventory pooling achievable by rationalizing product lines can be very substantial. Furthermore, we quantify the benefit of using a platform strategy to mitigate the effects of a broad product line on production costs. Finally, we propose an additional, attribute-based measure of product line breadth and find that product line breadth can work as a hedge against changes in demand conditions. For example, automakers that offer a broader range of fuel economy levels increase their market share and reduce their average discounts as gas prices become more volatile.

Pricing and Production Flexibility: An Empirical Analysis of the U.S. Automotive Industry
Antonio Moreno and Christian Terwiesch
We use a detailed data set from the U.S. auto industry spanning from 2002 to 2009 and a variety of econometric methods to characterize the relationship between the availability of production mix flexibility and firms’ use of responsive pricing. We find that production mix flexibility is associated with reductions in observed manufacturer discounts, resulting from the increased ability to match supply and demand. Under the observed market conditions, mix flexibility accounts for substantial average savings by reducing price discounting by approximately 10% of the average industry discount. We test three supplementary hypotheses and find that the reduction in discounts for vehicles manufactured at flexible plants is (1) higher for higher demand uncertainty, (2) higher for vehicles coproduced with vehicles that belong to a different segment, and (3) lower in situations with higher local competition.

How to Win in an Omnichannel World
David R. Bell, Santiago Gallino and Antonio Moreno
The omnichannel environment presents new challenges and opportunities for both information and product fulfillment. While all retailers need to effectively and efficiently manage fulfillment and information provision, there are important nuances to how this happens, depending on where and how the retailer got started and what kinds of improvement create the most leverage. This article delivers a customer-focused framework showing how to win in the omni-channel environment through critical innovations in information delivery and product fulfillment. The framework emerged from our research with both traditional and nontraditional retailers. To thrive in the new environment, retailers of all stripes and origins need to deploy information and fulfillment strategies that reduce friction in every phase of the buying process. This means simultaneously providing, in a cost-effective and narrative-enhancing way.

Doing Business with Strangers: Reputation in Online Service Marketplaces
Antonio Moreno and Christian Terwiesch
Online service marketplaces allow service buyers to post their project requests and service providers to bid for them. To reduce the transactional risks, marketplaces typically track and publish previous seller performance. By analyzing a detailed transactional data set with more than 1,800,000 bids corresponding to 270,000 projects posted between 2001 and 2010 in a leading online intermediary for software development services, we empirically study the effects of the reputation system on market outcomes. We consider both a structured measure summarized in a numerical reputation score and an unstructured measure based on the verbal praise left by previous buyers, which we encode using text mining techniques. We find that buyers trade off reputation (both structured and unstructured) and price and are willing to accept higher bids posted by more reputable bidders. Sellers also respond to changes in their own reputation through three different channels. They increase their bids with their reputation score (price effect) but primarily use a superior reputation to increase their probability of being selected (volume effect) as opposed to increasing their bid prices. Negative shocks in seller reputation are associated to an increase in the probability of seller exit (exit effect), but this effect is moderated by the investment that the seller has made in the site. We conclude that participants in this market are very responsive to the numerical reputation score and also to the unstructured reputational information, which behaves in a similar way to the structured numerical reputation score but provides complementary information.

Why Retailers Should Care about Net Neutrality: The Impact of Website Performance on Online Retail
Santiago Gallino, Nil Karacaoglu and Antonio Moreno
The share of e-commerce sales is rapidly increasing and so are the associated losses generated by website outages and slow websites. We leverage novel retail and website performance data to investigate the impact of website performance on online sales. This question is especially relevant in the current regulatory environment, given the ongoing policy debates around net-neutrality. Using two different research designs -- panel
data with fixed effects and generalized synthetic control with elastic net-- we estimate sizable adverse effects of website speed slowdowns on online sales, especially in the mobile channel. Our results show that decreases in website performance make customers less likely to place an order and undermine retailers' quest to turn website traffic into sales. The findings have important implications for the net neutrality debate and retailers'
website design decisions, specifically the selection of third-party content providers and the customized design
of mobile and desktop channels.

Opportunistic Returns and Dynamic Pricing: Empirical Evidence from Online Retailing in Emerging Markets
Chaithanya Bandi, Antonio Moreno, Donald Ngwe and Zhiji Xu
We investigate how dynamic pricing can lead to more product returns in the online retail industry. Using detailed sales data of more than two million transactions from the Indian online retail market, where price promotions are very common, we document two types of strategic customer behavior that have not been considered in previous research. First, customers who monitor product prices after purchase may initiate opportunistic returns because of price drops. Second, customers who anticipate a future return may strategically choose a payment method that facilitates product returns. Our logistic regression models indicate that (1) realized post-purchase price drops lead to a higher probability of return, and (2) anticipated price drops after purchase lead to a higher probability of using cash on delivery, a payment method with a lower return cost for consumers. Our findings are robust to alternative model specifications and sample selection procedures. We demonstrate that an optimal pricing policy should take into consideration the potential costs of two types of strategic customer behavior: opportunistic returns and strategic choice of payment method.

The Effects of Menu Costs on Supply Chain Efficiency: Evidence from Adoption of the Electronic Shelf Label Technology
Ioannis Stamatopoulos, Achal Bassamboo and Antonio Moreno
We use the adoption of electronic shelf labels (ESLs) by a major international grocery retailer in 2015 in the United Kingdom to identify the effects of reducing physical menu costs (operational costs of price adjustment) on supply chain efficiency. The ESL technology essentially eliminates the physical costs associated with price adjustment (e.g., costs of printing and distributing price tags). We find that the elimination of physical menu costs benefits all supply chain stakeholders (retailer, consumers, suppliers). In our setting, daily revenues increased, the average price per unit sold decreased, and daily sales volumes increased as a result of ESLs. We also find that ESL adoption increased price-adjustment volume, decreased the average size of a price adjustment, and decreased the batching of price changes across different products. Finally, we find that ESL adoption had a statistically significant effect on the volume of downward price changes, but not on the volume of upward price changes, which explains the direction of the change in operational outcomes.

The Wisdom of Crowds in Operations: Forecasting Using Prediction Markets
Achal Bassamboo, Ruomeng Cui and Antonio Moreno
Prediction is an important activity in various business processes, but it becomes difficult when historical information is not available, such as forecasting demand of a new product. One approach that can be applied in such situations is to crowdsource opinions from employees and the public. Our paper studies the application of crowd forecasting in operations management. In particular, we study how efficient crowds are in estimating parameters important for operational decisions that companies make, including sales forecasts, price commodity forecasts, and predictions of popular product features. We focus on a widely adopted class of crowd-based forecasting tools, referred to as prediction markets. These are virtual markets created to aggregate crowds' opinions and operate in a way similar to stock markets. We partnered with Cultivate Labs, a leading company that provides a prediction market engine, to test the forecast accuracy of prediction markets using the firm's data from its public markets and several corporate prediction markets, including a chemical company, a retail company and an automotive company. Using information extracted from employees and public crowds, we show that prediction markets produce well-calibrated forecasting results. In addition, we run a field experiment to study the conditions under which groups work well. Specifically, we explore how group size plays a role in the accuracy of the forecast and find that large groups (e.g., 18 participants) perform substantially better than smaller groups (e.g., 8 participants), highlighting the importance of group size and quantifying the right sizes needed to produce a good forecast using such mechanisms.

Inventory Auditing and Replenishment Using Point-of-sales Data
Achal Bassamboo, Antonio Moreno and Ioannis Stamatopoulos
We study how inventory managers can fully utilize point-of-sales (POS) data for the design of inventory auditing and replenishment strategies that account for the existence of phantom inventories. Events such as spoilage, expiration, employee theft, and customer shoplifting reduce available inventories in retail stores without these reductions being reflected in inventory records. As a result, inventory records often include phantom inventories, i.e., units of good present on inventory records but not actually available for sale. These phantom inventories cause replenishment delays and stockouts which ultimately hurt service levels. The optimal policy in the presence of phantom inventories is complex. We analyze the structure of the problem using tools from discrete mathematics and dynamic programming to derive a simple policy which performs close to the optimal policy and rarely acts sub-optimally. We propose a simple policy based on a threshold on the estimated fraction of demand to be met on a given day conditional on the POS data up to that day, a statistic that we refer to as the daily expected service level. Our policy is easy to compute and interpret, and can thus offer an attractive solution for inventory managers.

Operations in the On-Demand Economy: Staffing Services with Self-Scheduling Capacity
Itai Gurvich, Martin Lariviere and Antonio Moreno
Motivated by recent innovations in service delivery such as ride-sharing services and work-from-home call centers, we study capacity management when workers self-schedule. Our service provider chooses capacity to maximize its profit (revenue from served customers minus capacity costs) over a horizon. Because demand varies over the horizon, the provider benefits from flexibility to adjust its capacity from period to period. However, the firm controls its capacity only indirectly through compensation. The agents have the flexibility to choose when they will or will not work and they optimize their schedules based on the compensation offered and their individual availability. To guarantee adequate capacity, the firm must offer sufficiently high compensation. The goal of this paper is to examine how a firm that allows its agents to self schedule solves this problem.
An augmented newsvendor formula captures the tradeoffs for the firm and the agents. If the firm could keep the flexibility but summon as many agents as it wants (i.e,. have direct control) for the same wages it would not only generate higher profit, as is expected, but would also provide better service levels to its customers. If the agents require a "minimum wage" to remain in the agent pool they will have to relinquish some of their flexibility. To pay a minimum wage the firm must restrict the number of agents that can work in some time intervals.
The costs to the firm are countered by the self-scheduling firm's flexibility to match supply to varying demand. If the pool of agents is sufficiently large relative to peak demand, the firm earns more than it would if it had control of agents' schedules but had to maintain a fixed staffing level over the horizon.

Pros vs Joes: Agent Pricing Behavior in the Sharing Economy
Jun Li, Antonio Moreno and Dennis J. Zhang
One of the major differences between markets that follow a “sharing economy” paradigm and traditional two-sided markets is that the supply side in the sharing economy often includes individual nonprofessional decision makers, in addition to firms and professional agents. Using a data set of prices and availability of listings on Airbnb, we find that there exist substantial differences in the operational and financial performance of professional and nonprofessional hosts. In particular, properties managed by professional hosts earn 16.9% more in daily revenue, have 15.5% higher occupancy rates, and are 13.6% less likely to exit the market compared with properties owned by nonprofessional hosts, while controlling for property and market characteristics. We demonstrate that these performance differences between professionals and nonprofessionals can be partly explained by pricing inefficiencies. Specifically, we provide empirical evidence that nonprofessional hosts are less likely to offer different rates across stay dates based on the underlying demand patterns, such as those created by major holidays and conventions. We develop a parsimonious model to analyze the implications of having two such different host groups for a profit-maximizing platform operator and for a social planner. While a profit-maximizing platform operator should charge lower prices to nonprofessional hosts, a social planner would charge the same prices to professionals and nonprofessionals.

Research Summary
Overview
by
Antonio Moreno
One major theme of Professor Moreno’s research has been retail channel integration and so-called “omnichannel retail.” In omnichannel retail, retailers provide their customers with a shopping experience that may involve different channels in a way that aims to be seamless. For example, many large retailers today allow customers to reserve products online and pick them up at the store where they are stocked, return products purchased online at physical stores, or buy products online and have them shipped to a store to pick up when convenient. In order to offer these functionalities, retailers need to integrate their channels. This is recognized currently by practitioners as one of the most important changes in retail, one that dramatically affects retailers’ operations – especially existing inventory models. Professor Moreno’s multidisciplinary work in this area – combining approaches from marketing, operations, and information systems – has helped bring such practically relevant issues to the attention of the operations management community.
In another stream of research, Professor Moreno has sought to understand the operational implications of novel features of (increasingly important) business models based on platforms, such as the fact that services often are provided by independent contractors who make decisions in response to available information and incentives, or the fact that many of these service providers are nonprofessionals. He has also empirically studied fundamental questions in operations strategy, such as how pricing and production flexibility interact. Finally, he has done work in the area of retail and supply chain analytics, developing models that can help firms make better decisions such as improving forecasts or inventory replenishment decisions.
