The paper aims to investigate the dynamic relationship between working capital management and firm profitability for a sample of firms from eight European Union (EU) countries for the period 2006–2015.

The panel regression model is used in the study. Firm profitability is measured using the return on assets (ROA) ratio, whilst cash conversation cycle, financial leverage, size, tangibility and cash flow ratio are used as independent variables. The novelty of this study is the use of cash flow ratio to develop the analysis firms by dividing them as healthy and nonhealthy.

The paper reveals that working capital management affects firm profitability, and a positive relationship exists between them. The paper shows differences of working capital management and firm profitability across countries. The striking result of this study is that an inverted U-shape relationship exists between working capital management and firm profitability. Whereas the findings suggest that firms should be as close as possible to the optimal length of cash cycle to increase profitability, and managers should give a priority to working capital optimization.

The authors consider results of this study relevant to both researchers and business policymakers in the field of working capital management policies.

The purpose of this paper is to assess the survival probability among patients with liver trauma injury using the anatomical and psychological scores of conditions, characteristics and treatment modes.

A logistic model is used to estimate 173 patients’ survival probability. Data are taken from patient records. Only emergency room patients admitted to University Hospital of Trauma (former Military Hospital) in Tirana are included. Data are recorded anonymously, preserving the patients’ privacy.

When correctly predicted, the logistic models show that survival probability varies from 70.5 percent up to 95.4 percent. The degree of trauma injury, trauma with liver and other organs, total days the patient was hospitalized, and treatment method (conservative vs intervention) are statistically important in explaining survival probability.

The study gives patients, their relatives and physicians ample and sound information they can use to predict survival chances, the best treatment and resource management.

This study, which has not been done previously, explores survival probability, success probability for conservative and non-conservative treatment, and success probability for single vs multiple injuries from liver trauma.

The purpose of this paper is to measure the effect of superstar gig workers, defined as independent contractors who are the most successful in their field, on shareholder value. Gig workers comprise as much as 33% of the workforce and are projected to exceed 50% by 2028. Thus, understanding their impact on shareholder value is important.

This paper uses OLS regression analysis. To establish causality regarding wealth effects, the sudden deaths of superstar gig workers are used. To facilitate the uncontaminated measurement of wealth effects, sudden deaths that coincide with a significant event on a [−3, 3] window about the death event are not used.

The sudden death of a superstar gig worker causes shareholder wealth to increase significantly by 0.35% or almost $1.5m. Rational and behavioral explanations are offered for this result.

Generalizability is limited because data on superstar gig workers in traditional corporations are unavailable. For this reason, this paper uses the only available data, namely, data on superstar wrestlers, who are contracted to perform in matches (i.e. “gigs”) in a lucrative promotion (e.g. World Wrestling Entertainment (WWE)). Future research could examine the effect of corporate gig workers on shareholder value if the data become available at some point.

This paper is the first to document the effects of any type of gig worker, whether superstar or regular, on shareholder value.
