Purpose The purpose of this paper is to examine the effects of working capital management on firm valuation, profitability and risk. Design/methodology/approach The paper uses a panel data set of 497 firms covering the period 2007 to 2016. The authors test the effects of working capital management on firm valuation, profitability and risk using the panel data methodology that includes firm and year fixed effects regressions. Findings The authors find a significantly negative relationship between net working capital (NWC) and firm valuation, profitability and risk. The results suggest that, in managing working capital, firm managers must make a trade-off between their objectives for profitability and risk control. Working-capital management is of particular importance in firms with less access to capital; it is also important when firms are expanding their investments during periods of economic recovery. Originality/value This paper contributes to the literature in several ways. First, to my knowledge, it provides the most comprehensive investigation, to date, on the relationship between working capital management and firm valuation, profitability and risk in an emerging market. Second, this study documents the existence of an optimal level of NWC in an emerging market. Third, firm performance, as measured in both market and accounting value, can be improved with efficient working capital management. Finally, the study includes the impact of the business cycle in an analysis of the effects of working capital management on firm performance.

Purpose This paper aims to examine the impact of government ownership on the cost of debt and firm valuation in listed Vietnamese companies for the period 2007 to 2016. Design/methodology/approach The authors use both the generalised methods of the moment (GMM) and the ordinary least squares (OLS) regressions to analyse a panel data spanning over the period 2007 to 2016 in the markets of Vietnam. Further, the instrumental variable is used in the paper. Findings The authors find that firms with relative higher government stockholdings or state-owned companies where the government owns 50 per cent or more of shares outstanding enjoy a lower cost of debt compared to the other firms. Consequently, these firms have higher firm valuation and profitability. The results are robust for both the GMM and the OLS regressions. Further, firms that no longer retain government ownership have a higher cost of debt than the other firms. The results of the paper imply the importance of political connections in businesses in the market of Vietnam. Originality/value This paper connects the relationship between government ownership and the cost of debt with the relationship between government ownership and firm valuation. The paper tests the relationship between the cost of debt and government ownership using both OLS and GMM specifications and the results are robust for both approaches. The manuscript uses an instrumental variable to show that government ownership has a positive impact on higher firm performance through reducing cost of debt. Further, this paper addresses the possible issue of endogeneity.

Purpose This study aims to examine the effects of audit quality on earnings management and cost of equity capital (COE) considering the impact of two owner types: government ownership and foreign ownership. Design/methodology/approach The study uses a panel data set of 236 Vietnamese firms covering the period 2007 to 2017. Because the two main dependent variables of the COE capital and the absolute value of discretionary accruals receive fractional values between zero and one, the paper uses the generalised linear model (GLM) with a logit link and the binomial family in regression analyses. The paper uses numerous audit quality measures, including hiring Big 4 auditors or the industry-leading Big 4 auditor, changing from non-Big 4 auditors to Big 4 auditors or the industry-leading Big 4 auditor, and the length of Big 4 auditor tenure. Big 4 companies include KPMG, Deloitte, EY and PwC, whereas the non-big 4 are the other audit companies. Findings The study finds a negative relationship between audit quality and both the COE capital and income-increasing discretionary accruals. The effects of audit quality on discretionary accruals and the COE capital depend on the ownership levels of two important shareholders: the government and foreign investors. Foreign ownership is negatively associated with discretionary accruals; however, the effect is more pronounced in the sub-sample of state-owned enterprises (SOEs), the firms where the government owns 50% or more equity, than in the sub-sample of Non-SOEs. Originality/value To the best of the knowledge, no prior similar study exists that used the GLM with a logit link and the binomial family regression. Global investors may be interested in understanding how unique institutional settings and capital markets of each country impact the financial reporting quality and cost of capital. Further, policymakers of developing markets may have incentives to improve the quality of financial reporting and reduce the cost of capital which should result in attracting more foreign investments.

Purpose The purpose of this paper is to examine the joint effects of state ownership and tax rate cuts on accounting conservatism, considering the different levels of foreign ownership in the context of Vietnam. Design/methodology/approach The paper uses ordinary least squares regressions and a data set of 405 firms covering the period 2007 to 2019. The manuscript uses three measures of accounting conservatism: Basu’s 1997 timeliness of earnings, Basu’s 1997 earnings persistence and the book-to-market ratio. Findings State-owned enterprises (SOEs) adopt less accounting conservatism than non-SOEs; however, the result is only robust in firms with foreign ownership being lower than the foreign ownership median. Firms increase accounting conservatism in the year immediately prior to the year that the tax rate cuts become effective. An SOE possesses an unusual conflict both as a taxpayer and in having its controlling interest held by the government, which is both a tax creator and a tax collector. Interestingly, the increase in accounting conservatism prior to the year of the tax rate cuts is more pronounced for non-SOEs than SOEs. Practical implications This research is beneficial to investors and policymakers where the government is both the taxpayer and tax collector and in emerging markets where foreign investment is local firms’ important financing. Originality/value To the best knowledge, this study is the first in examining the joint effects of state control and tax rate cuts on accounting conservatism.
