Long-term relationships between international share prices

Integration of Pakistan's stock market with the stock markets of top ten developed economies

This study examines the integration of Pakistan's Stock Market with the stock markets of the top ten largest economies in the world-USA, China, Japan, Germany, the UK, India, France, Italy, Brazil, and Canada-from January 2015 to October 2020. To examine long- and short run integration, this study employed Johansen and Juselius co-integration and pair-wise Granger causality tests. In the long run, the results indicated that Pakistan's Stock Market is not integrated with these markets. This implies that the market is more attractive in portfolio diversification for international investors, and vice versa. In the short run, the results revealed that, except for China, Pakistan's stock market integrates with the remaining nine markets. However, Pakistan's stock market exhibits a bidirectional relationship with the USA, Japan, Germany, the UK, and France in the lead-lag relationship. However, its relationship with India, Italy, Brazil, and Canada is unidirectional, with Pakistan's stock market leading, while these markets are following. For Pakistani investors, China is the optimal market, and vice versa. Importantly, our findings help policymakers to comprehend Pakistan's dynamic relationship with its trading partners. To the best of our knowledge, no prior study has employed advanced techniques to address the time-varying correlation among the selected markets. By determining Pakistan's stock market integration with its trading partners, this study aimed to fill this empirical literature gap.

Assessing the impact of transition from nonrenewable to renewable energy consumption on economic growth-environmental nexus from developing Asian economies

Greenhouse gasses have adverse effects on global warming and air pollution and need to be optimized by minimizing the contributing factors. This work analyzes the effects of economic growth and energy resources (renewable and nonrenewable) on the emissions of greenhouse gasses (GHG). A 2000-2016 panel data from 25 developing Asian countries is analyzed through a robust Random Effect (RE) approach and Hausman Taylor Regression (HTR). Findings show a positive correlation between economic growth and energy consumption, while a 1% increase in renewable energy consumption results in a 0.193% decrease in carbon emissions. Economic growth and renewable energy are positively correlated in both the short and long term, which implies a valid feedback hypothesis. The findings indicate the significant contribution of nonrenewable energy resources to greenhouse gas emissions and the positive impact of renewable resources on greenhouse gas emissions' control. Furthermore, this study highlights the potential of developing Asian economies to preserve the environment through more robust regional environmental policies and renewable energy resources. In light of this study's findings, policymakers in Asian developing economies should develop policies on Renewable Energy infrastructure (RE) to improve GDP and reduce greenhouse gas emissions.

Dynamic linkages among ASEAN‐5 emerging stock markets

Purpose

The purpose of this paper is to empirically explore market integration among five selected Association of Southeast Asian Nations (ASEAN) emerging markets (Malaysia, Thailand, Indonesia, the Philippines and Singapore) during the pre‐ and post‐1997 financial crisis periods.

Design/methodology/approach

Employs two‐step estimation, cointegration and generalized method of moments (GMM).

Findings

The study finds that the stock markets in the ASEAN region are cointegrated both during the pre‐ and post‐1997 financial crisis. However, the markets are moving towards a greater integration, particularly during the post‐1997 financial crisis. Finally, as measured by the error correction terms, except the emerging market of Indonesia, all other ASEAN markets appear to be the important bearers of short‐run adjustment to a shock in the long‐run equilibrium relationships in the region both during the pre‐ and post‐crisis periods.

Research limitations/implications

The study only focuses on stock markets of the five founding members of ASEAN, i.e. Malaysia, Indonesia, Thailand, Singapore and the Philippines.

Practical implications

The paper reveals that unlike during the pre‐crisis period, the long‐run diversification benefits that can be earned by investors across the ASEAN markets in the post‐crisis period tend to diminish.

Originality/value

The study is among the first to use two‐step estimation, cointegration and GMM to re‐examine market integration either in the emerging or developed markets.
