The Causal Effect of Access to Finance on Productivity of Small and Medium Enterprises in Vietnam

Abstract

In many developing countries, obtaining financial services at affordable rates and fair terms has been a significant challenge for small and medium enterprises (SMEs). However, this issue has not been paid much attention in Vietnam, even though SMEs account for about 95% of total enterprises and the financial market of the country has not been well developed. This study investigates the causal effects of access to finance on productivity of SMEs operating in the manufacturing sector in Vietnam. Productivity was measured as the total factor productivity (TFP) obtained by production function estimation using the Levinsohn and Petrin approach. Regarding financial accessibility, two factors covered the extent to which firms might have a bank loan or overdraft facility were employed. To study the causal inferences of access to finance on firm productivity, the research adopted the difference-in-differences (DID) approach, as well as the propensity score matching (PSM) coupled with DID technique. The empirical results indicated that improving the financial accessibility could directly enhance firm productivity. Particularly, it was shown that firms having access to a bank loan could significantly improve TFP by approximately 8.6% in the DID model and about 9% in the PSM-DID model. Meanwhile, the firm average TFP increased by approximately 12.3% and 15.7% in simple DID and PSM-DID models, respectively, when firms had an overdraft facility. These findings suggest that the government should put more effort into assisting SMEs in generating bankable projects, and create a sound and healthy financial environment to stimulate firms’ access to finance, which will ensure their sustainability and growth.

The Relationship between Environmental Regulation and Green Total Factor Productivity in China: An Empirical Study Based on the Panel Data of 177 Cities

“…They also supports the pollution paradise hypothesis in China's rapid industrialization process. However, the research conclusions of fixed asset investment are not consistent with the views of Antonietti and Marzucchi [36], but are consistent with those of Daina et al [37] and Giang et al [38]. More specifically, fixed asset investment does not necessarily promote the development of a green economy and green total factor productivity.…”

Financial Inclusion and Firms Growth in Manufacturing Sector: A Threshold Regression Analysis in Selected Asean Countries

“…However, credit access among firms needs to be controlled, as the impact of this excess credit may not significantly affect firm growth to some extent. The previous study by Huong Giang et al (2019) and Fowowe (2017) argued that financial access has a positive effect (monotonic relationship) on firm growth. There is a possibility of financing unprofitable investment activities if access to finance is not controlled, whereby high economic freedom could affect firm growth.…”

How Heterogeneous Are the Determinants of Total Factor Productivity in Manufacturing Sectors? Panel-Data Evidence from Vietnam

“…The paper contributes to the literature in several ways. First, our work extends the current literature (Castellani and Giovannetti 2010;Kreuser and Newman 2018;Kim 2018;Ngo and Tran 2020;Ngo and Nguyen 2019;Giang et al 2019) by accounting for heterogeneity in examining the determinants of TFP at the firm level in a dynamically emerging economy. Second, we examine the TFP determinants in detail by exploring the issues at the levels of 21 manufacturing sectors, and not at level of the aggregated industry.…”
