However, imbalances between pay and workload of different tasks could result in higher priority tasks with low pay-to-workload ratio receiving poorer service. We investigate this hypothesis, showing turnaround time is decreasing in pay-to-workload for lower priority tasks, whereas it is increasing in workload for high-priority tasks.

To develop insight on factors contributing to this institutionalization process, this paper relies on the literature in institutional entrepreneurship and investigates sharing economy platforms in China, highlighting institutional voids that are encountered, and suggesting ways on how they can be overcome. These insights are derived through a multiple case study approach involving 61 semi-structured interviews with managers from eight sharing economy platforms (DiDi, Uber China, Huochebang, Yunmanman, OfO, Mobike, Evcard, and Zhida) across four sharing economy industries in China (ride-sharing, logistics-sharing, bike-sharing, and car-sharing). The findings highlight the importance of exchange and collaboration with stakeholders (allies) in the network, as well as the effective response to emerging issues through the adaptation of the business models. In addition, mergers and acquisitions, and the role of government are identified as critical components in aiding platforms in their progression toward institutionalization. Further cognitive, regulative, and normative factors are found to represent valuable institutional pillars that serve as a fertile foundation throughout the institutionalization process.

Highlighting the information asymmetry in supplier evaluation and using signaling theory, we argue that for a focal buyer, a supplier's downstream ego-network instability, that is, other buyers' turnover in a supplier's network from one period to the next, acts as a <i>signal</i> of supplier unreliability, thereby reducing the price that the buyer pays to the supplier in a service exchange. Furthermore, we suggest that focal buyer–supplier relationship strength and structural equivalence weaken the negative effect of instability because the buyer has a more direct and positive experience with the supplier. Using a dataset of 3263 unique dyads formed by 260 buyers (shipoperators) and 493 suppliers (shipowners) during the 2000–2018 period in the container shipping charter market, we find support for our hypotheses, except for the contingent effect of structural equivalence. Our study contributes to signaling literature and network research by developing a supplier's downstream ego-network instability as a salient heuristic for a focal buyer's pricing decisions.

Lee,&nbsp;Chris Voss","doi":"10.1002/joom.1250","DOIUrl":"10.1002/joom.1250","url":null,"abstract":"&lt;p&gt;Since the first case was identified, COVID-19 has spread to more than 200 countries. As of October 25, 2022, it had resulted in over 6 million deaths and 600 million confirmed cases. The rapid widespread of COVID-19 led to large-scale disruptions with major supply and demand shocks in supply chains, causing significant negative impacts on the global economy. The World Bank reported that the world GDP growth rate for 2020 was −3.27%, indicating the worst recession since 1961.&lt;/p&gt;&lt;p&gt;First, the initial epidemic-control efforts blocked the flows of raw materials across the world, and limited labor movements by imposing temporary travel restrictions. As a result, many firms struggled with supply disruptions and labor shortages, setting off a chain reaction of disruption in global supply chains. Fortune (2020) reported that as of February 21, 2020, 94% of the &lt;i&gt;Fortune 1000&lt;/i&gt; companies had experienced supply-chain disruptions due to COVID-19.&lt;sup&gt;1&lt;/sup&gt; According to the &lt;i&gt;Institute for Supply Management&lt;/i&gt;, almost 75% of companies reported supply-chain disruptions in some capacity due to coronavirus-related transportation restrictions.&lt;sup&gt;2&lt;/sup&gt; A survey conducted by the &lt;i&gt;National Association of Manufacturers&lt;/i&gt; reported that 78.3% of manufacturers believed that COVID-19 had a significant negative influence on their financial performance, and 35.5% of them had experienced some type of supply chain disruptions.&lt;sup&gt;3&lt;/sup&gt;&lt;/p&gt;&lt;p&gt;Second, the demand for essential personal-protective equipment increased dramatically because the virus was easily transmitted from person to person through air-borne droplets; accompanied by a drop in the need for other manufactured products (Nicola et al., &lt;span&gt;2020&lt;/span&gt;). For example, COVID-19 had caused a surge in the demand of face masks that were necessary to prevent infection among frontline workers (who were directly exposed to the virus when treating infected patients or conducting nucleic acid tests) and individuals in public places. China was the main producer of masks at the start of the crisis, accounting for approximately half of world production. In January 2020, China could produce 20 million masks per day, which was insufficient to equip even just healthcare workers in China. As a result of extensive efforts by the government and companies, Chinese production increased six-fold and reached 116 million masks per day by the end of February, 2020. But even this was insufficient to meet its own demand, and China imported a large quantity of masks. Similarly, Germany also experienced very limited availability of face masks in the spring of 2020. To increase the supply of face masks, the German government contracted with hundreds of companies and introduced a series of incentives to encourage local, non-medical manufacturers to temporarily transform to produce masks.&lt;/p&gt;&lt;p&gt;More generally, demand patterns for supplies of all types became less predictable from the beginning of pandemic.

We propose a reference-dependent behavioral model that explains the near-miss bias. The findings of a laboratory experiment show that production quantities are evaluated based on realized profits and are below the optimal model prediction. Contracts associated with lower perceived severity, that is, the ratio of flat penalty to wholesale price, result in lower production quantities than those with higher perceived severity, even though the standard model does not predict any effect.

We study three drivers of CABG readmission risk—hospital and surgeon case volume, variation in surgeon volume, and surgeon familiarity with hospitals. Drawing on unique patient data sets of CABG surgeries spanning 3 years, we study the relationships between hospital and surgeon case volume, readmission risk, and postoperative length of stay (PLOS). We find evidence of an inverted U-shaped relationship between case volume and readmission risk and a U-shaped relationship with PLOS. Our results also indicate that surgeon volume variation moderates the relationship between surgeon volume and readmission risk, where readmission risk increases with greater variation in surgeon volume.
