Volatility spillovers in the US-China financial markets: Evidence from BEKK-GARCH model

2024-12-13T22:13:26-06:00

This study investigates the spillover effects of volatility between the financial markets of the US and China using the BEKK-GARCH model on daily data from 4 January 2016 to 31 December 2021. The results, validated by the Wald test, reveal significant findings: First, the internationalization of the RMB has enhanced China's influence on the USD, resulting in volatility spillovers between the US dollar index and China's foreign exchange market. Second, while volatility spillovers exist between Chinese and US stock markets, the ARCH effect has weakened following the trade war. Finally, there are spillover effects between the Chinese and US bond markets, though these are less pronounced compared to the foreign exchange markets. These findings highlight the evolving nature of volatility spillovers between the US and Chinese financial markets, especially in the context of a trade war. The practical implications suggest that investors and policymakers should closely monitor these spillover effects to manage risks better and make informed decisions in an increasingly interconnected global market.

The impact of stock liquidity on stock price crash risk: Empirical research on listed firms in Vietnam

2025-01-21T01:51:50-06:00

Vietnam's stock market is now highly developed and significant to the economy of the country. Many previous researches have studied the factors that affect stock prices on the stock market. Therefore, in this article, the authors examine the impact of stock liquidity on stock price crash risk with a sample space of companies on the Ho Chi Minh City Stock Exchange (HOSE) from 2016 to 2022. By using the linear regression research model, the authors found that stock liquidity has a negative impact on stock price crash risk. In this model, stock price crash risk will be the dependent variable, whereas stock liquidity will be the explanatory variable, which will ultimately determine the accuracy and suitability of the model through observed data. This topic provides considerable value to the depth of knowledge on stock liquidity and stock price crash risk in emerging markets and is helpful for emerging markets to monitor stock liquidity there. Additionally, this study offers potential strategies to manage stock price crash risk, which is valuable information for investors, authorities, regulators, and policymakers.

Innovation and economic growth in middle-income countries: The moderating role of remittances

2025-02-20T04:11:09-06:00

The prime objective of this paper is to examine the direct and moderating role of remittances in the innovation-growth nexus in MICs. Middle-income countries (MICs) can drive global economic growth by utilizing 75% of the population through technological development and boosting GDP by over one-third of the total. However, using human resources effectively and maintaining technical advancement standards in response to rapid economic changes remain a significant challenge. The study utilizes the "2^nd generation unit root test and the panel corrected standard errors (PCSE) and the feasible generalized least squares (FGLS)" approaches. The FGLS and "Dumitrescu-Hurlin (D-H)" causality tests are applied to confirm the robustness of the PCSE approach. The study highlights the distinct and interconnected effects of remittances and innovation on economic growth in MICs, emphasizing their mutually reinforcing role in sustained growth. The interactive span demonstrates that remittances functioned as a substitute in the innovation-growth association. Finally, the study reveals a bidirectional causal affiliation between remittances and economic growth and a unidirectional causal connection between economic growth and innovation. MICs should enhance remittance transfer systems, invest in innovation, enhance skills, utilize public-private partnerships for efficient allocation, and balance entrepreneurship with macroeconomic stability.
