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 explore the potential benefits of an optimal vs observed working capital; the latter being measured by cash conversion cycle (CCC). Optimal CCC is defined and measured as the CCC that maximizes sales in the last four quarters. The initial exploratory results show that optimal CCC has been shorter than the observed. In addition, shorter CCC is accompanied by higher return on investment.

The authors use various statistical tools to analyze the differences between determinants of observed and optimal CCC. These statistical tools include Johansen cointegration test, linearity, normality tests, cointegration regression and Granger causality. The authors also use the benefits of discriminant analysis in order to reach a Z-score model that can be used for monitoring the move from an observed to optimal working capital.

The results show that: significant association exists between volatility of sales and CCC; sales volatility and lagged growth of sales carry relatively the highest weights when a firm moves from observed to optimal CCC; shorter CCC is associated significantly with higher profitability; the observed CCC adjusts to an optimal level; as inflation rises causing potential rise in cost of goods sold, firms prefer staying away from optimal levels of working capital; as economic growth slows down, firms stay at the current level of observed working capital; the results are subject to industry and size effects; and the DJIA and NASDAQ listed firms adjust observed CCC to optimal level slowly.

This paper offers three advances in the literature. The first advance is that the paper determines an optimal level of working capital empirically. To the best of the authors’ knowledge up to the date of submission, other related studies did not include an empirical solution to determine optimal working capital. The second advance is that the paper develops an empirical discriminant model that can be used for monitoring firms’ move from an observed to optimal working capital. The third advance is that optimal working capital shows the empirical integration between short-term and long-term investments that results in an improvement to firm’s liquidity and profitability.

The purpose of this paper is to examine the impact of working capital management (WCM) on profitability under different financial conditions (constraint/unconstraint) and WCM policy (aggressive/conservative). Furthermore, the study investigates the existence of optimal working capital levels under different financial conditions and WCM policy.

Two-step system generalized method of moments and fixed effect models are used to analyze the data collected from Prowess database from 2011 to 2020 for a sample of 1,104 Indian manufacturing companies.

The study finds an inverted U-shaped relationship between working capital and profitability in all financial conditions and working capital policy. This finding advocates the existence of an optimal level of working capital that equates the costs and benefits of holding working capital to maximize the companies’ profitability. However, holding working capital beyond the optimal level negatively affects profitability. Companies under financial constraints with aggressive working capital policies have the lowest optimal cash conversion cycle (CCC). Furthermore, the relationship of working capital with profitability and the optimal CCC varies owing to firm age and industry group.

To the best of the authors’ knowledge, this is the first paper that incorporates the impact of working capital on firm’s performance from both financial constraint (unconstraint) and aggressive (conservative) working capital policy perspectives in the Indian context. Furthermore, this study also contributes in terms of reflecting the effect of firm age and industry in determining the optimum CCC of the firms.

The purpose of this paper is to report the results of an investigation of the relationship between working capital level, measured by the cash conversion cycle (CCC) and profitability of small and medium enterprises (SMEs).

The paper employs panel data regression analysis on a sample of 160 Alternative Investment Market (AIM)-listed SMEs for the period from 2005 to 2010.

The empirical results show that there is a concave relationship between working capital level and firm profitability and that there is an optimal working capital level at which firms’ profitability is maximised. Furthermore, an examination as to whether or not deviations from the optimal working capital level reduce firm profitability indicate that deviations above or below the optimum decrease profitability.

The sample is limited to AIM-listed SMEs, and therefore the findings cannot be generalised to all firms.

Overall, the evidence suggests that firms should strive and attain the optimal working capital level in order to maximise their profitability.

The results are of importance to both SMEs and policy makers providing insight into the nature of CCC and its relationship to SMEs profitability.

The purpose of this research is to examine Micro-, small- and medium-sized enterprises (MSMEs). Which have limited access to financial resources from financial intermediaries. Thus, resource allocation is a primary concern for them.

This research studies the determinants of cash conversion cycle components and cash flow of MSMEs operating in Ecuador. This study examined a robust sample of 19,680 firms from 2000 to 2020, using the two-step generalized methods of moments to control for endogeneity and multicollinearity of independent variables issues.

The sample was divided into working capital intensive and fixed capital intensive firms. It was found that in every segment (micro-, small- and medium-sized), the majority of firms are working capital intensive and their average return is higher. This implies that small business owners assign the majority of their resources to current assets, which thus far have enabled them to achieve higher profitability.

Research investigated Ecuadorian MSMEs in a dollarized developing environment. Scrutinizing working capital intensive vs fixed capital intensive.

This paper evaluates the working capital management (WCM) efficiency of the Indian manufacturing industries through data envelopment analysis (DEA) and empirically investigates the influence of several exogenous variables on the WCM efficiency.

WCM efficiency was calculated using BCC input-oriented DEA model. Further, the panel data fixed effect model was used on a sample of 1391 Indian manufacturing firms spread across nine industries, covering the period from 2008 to 2019.

Firstly, the WCM efficiency of Indian manufacturing industries has been stable over the analysis period. Secondly, the capacity to generate internal resources, size, age, productivity, gross domestic product and interest rate significantly influence WCM efficiency.

First, the selected study period has observed various economic uncertainties including demonetization and recession, so the scenario might differ in normal conditions or country-wise. Second, the findings might not be generalizable to the developed economies, since the current study sample belongs to a developing economy, which further provides scope for comparative study.

An efficient model for managing the working capital comprising most vital determinants could enhance the firms' valuation and goodwill. Also, this study would be helpful for financial executives, manufacturers, policymakers, investors, researchers and other stakeholders.

This study estimates the industry-wise WCM efficiency of the Indian manufacturing sector and suggests measures to the concerned parties on areas to focus on and provide evidence on the estimated relationships of firm-level and macroeconomic determinants with WCM efficiency.

The purpose of this paper is to examine the relationship between working capital management (WCM) and firm performance in the context of the Chinese economy. Specifically, it investigates the effects of ownership structures as an internal factor and of institutional environments (IE) as an external factor shaping this relationship.

The study applies two-way fixed effect regression models to a sample of Chinese listed manufacturing firms for the period of 2010 to 2017. WCM is measured by cash conversion cycles (CCC); profitability is measured by core profit ratios; ownership structures are classified based on state-owned enterprises (SOEs) and non-SOEs; and IEs are measured from dimensions of factor markets (FM) and legal systems (LS).

First, the results show a negative relationship between CCC and firm performance. Second, the negative relationship between CCC and profitability is significant for non-SOEs but not for SOEs. Third, both the FM and LS strengthen the negative association between CCC and profitability. Fourth, the moderating effect of FMs and LSs is evident for non-SOEs only. The results hold when using alternative measures of WCM and profitability and while controlling for additional variables.

The current study shows that while WCM has a significant effect on the profitability of Chinese firms, such an effect greatly depends on the ownership structures and IE involved. The results thus offer important implications in helping the Chinese government create better IEs and in allowing manufacturing firms to improve upon their WCM practices.

The purpose of this paper is to examine the relationship between working capital management (WCM) and firm profitability for a sample of 437 non-financial Indian companies.

The study is based on secondary financial data obtained from Capitaline database, pertaining to a period of ten years. This study employs two-step generalized method of moments (GMM) techniques to arrive at results.

The results of the study confirm the inverted U-shape relationship between WCM and firm profitability. In addition, the authors also found that the firms should complete its CCC on an average by 63 days.

Unlike prior studies that found a linear relationship between WCM and firm profitability. This study provides newer evidence for an inverted U-shaped relation between investment in working capital and firm profitability in India. In addition, this study uses GMM to control the potential problems of endogeneity.

This paper aims to report the results of an investigation of the relative importance of working capital management, measured by the cash conversion cycle (CCC), and its components (inventory, accounts receivable and accounts payable) to the profitability of SMEs.

The paper employs panel data regression analysis and a questionnaire survey on a sample of 133 Alternative Investment Market (AIM) listed SMEs. The panel data analysis utilises financial data for the period 2005 to 2009. The questionnaire survey results are based on 19 SMEs that responded.

Panel data analysis results show that the management of accounts payable (AP) and accounts receivable (AR) is important for SMEs profitability. However, AP management is relatively more important than AR management. Inventory (INV) and CCC management is not important for SMEs profitability. Questionnaire results suggest that management of CCC and all its components is perceived as important for SMEs profitability. In terms of relative importance, AR management is most important, followed by AP, INV and CCC respectively.

The sample is limited to AIM listed SMEs, and therefore the findings cannot be generalised to all companies.

Overall the results imply that the SMEs need to concentrate their limited resources on managing AR and AP in order to be more profitable.

The study is the first to investigate the relative importance of WCM and its components to SMEs profitability and use both regression analysis and questionnaire survey.

This study aims to examine the impact of working capital management (WCM) on firm performance. The authors pursue innovation by exploring how the level of financial constraints shapes the impact of WCM on corporate performance.

In this study, the generalized method of moments (GMM) is used to analyze a sample of 753 firms listed on ten Middle East and North Africa (MENA) emerging markets.

The authors' empirical analysis demonstrates that financially constrained firms are coerced to adopt an aggressive WCM approach to reduce investment in working capital, minimize financing costs and improve financial performance despite the risks associated with this strategy. Contrarily, financially unconstrained firms, uphold a high level of investments in working capital to grow sales and improve financial performance. The authors' results strongly reject the “one size fits all” approach of WCM. The authors assert that the degree of financial constraints largely defines the firm's optimal WCM approach.

The authors' study reveals to financial managers the importance of adopting an appropriate WCM strategy that fits firm-specific characteristics and financial flexibility. The authors' results urge policy makers to ease access to financing to all firms to enhance both their financial flexibility and ability to respond efficiently to emerging investment opportunities as well as develop resilience to economic slumps.

To the best knowledge of the authors, this is the first study that explores WCM and financial constraints in MENA emerging markets.
