Reactions of Long-run Private Consumption in Malaysia to Crises, Economic Leadership and Telecommunication Technology

We estimate the long-run reactions of private consumption in Malaysia to crises, economic leadership, information and communications technology (ICT), and other key determinants using time series econometrics. This study covers the quarterly sample from 1990:Q1 to 2020:Q4. We find that Malaysia's private consumption and its key determinants are cointegrated, demonstrating that a reliable long-run private consumption function can be estimated. We find that both economic and health crises, namely the Asian financial crisis in 1997/98, SARS and COVID-19 pandemic are likely to reduce private consumption in Malaysia. However, the long-run estimation results show that ICT and economic leadership are positively related to consumption. Therefore, policymakers should set the goal of encouraging the development of ICT infrastructure and good economic leadership in order to promote private consumption, which eventually sustains long-term economic growth and development.

Time-varying herding spillover for emerging countries: evidence from BRIC countries and Turkey

Purpose This study aims to investigate herding spillover in BRIC (Brazil, Russia, India and China) countries and Turkey under different regimes by using a time-varying approach. Design/methodology/approach The authors used the structural change model of Bai and Perron (1998). Findings The results indicate that there is an evidence of herding behaviour in the Chinese stock market in two different regimes. These regimes cover the recent global financial crisis and the period of Hong Kong protests. We also report the evidence of herding behaviour in the Turkish stock market in the regime covering the COVID-19 period. Findings of herding spillover show that there is a two-way herding among Russia and China during crises and high volatile regimes. Similarly, there exists a cross-country herding among Brazil and India during crisis regimes. Also, there is herding spillover from Turkey to Russia, China and Brazil during the global financial crisis, post-European debt crisis and COVID-19 periods respectively. Furthermore, it is also evident that there is a herding spillover from Russia and China to India during the period covering COVID-19. Originality/value To the best of the authors' knowledge, this is the first study that uses structural change approach to identify herding behaviour spillovers from the US stock market to BRIC countries and Turkey and to investigate the cross-country herding behaviour among BRIC countries and Turkey.
