This study examines the impact of foreign direct investments on ecological footprint along with other explanatory variables of 92 countries from the year 2001 to 2016. Here, we applied the panel quantile regression model to meet the purpose of our study as it considers unobserved country heterogeneity, unlike other statistical methods. The study reveals that foreign direct investment has a positive relationship with the ecological footprint in each quantile except one, which proves the constancy of the pollution haven hypothesis. Moreover, we also tried to detect the impact of economic growth, manufacturing value-added, the percentage of world exports, and institutional quality on the ecological footprint in this study. The findings of this study also reveal that economic growth and manufacturing value-added are negatively associated with the ecological footprint. With respect to the percentage of world exports and institutional quality, we found a positive relationship with the ecological footprint. From the result of our study, different policy implications have been proposed for host countries and foreign investors on improving the economy through foreign direct investment with minimal ecological footprint.

Engagement in international trade and investment affects the attainment of macroeconomic objective of a nation. The purpose of this research was to assess the effect of international trade and investment on economic growth of Bangladesh measured by GDP, GDP growth, per capita income, unemployment rate, and capital investment. Type of data was secondary, and nature of data was time series. Study period was from 2000-2018. Ordinary least square regression has been applied to explore the impact. The study showed that exchange rate significantly positively impacts, but foreign remittances significantly negatively impact GDP, per capita income, and capital investment. GDP growth is significantly influenced only by exchange rate, and international trade and investment have an insignificant impact on unemployment. The findings of the study are beneficial for national economic and industrial policymakers, government, ministry of commerce and industry, and Bangladesh Bank as formulating appropriate policy regarding exchange rate and foreign remittance could contribute to Bangladesh's economic growth.
