The selection of financing is a top priority for businesses, particularly in short- and long-term investment decisions. Mixing debt and equity leads to decisions on the financial structure for businesses. This research analyzes the moderate position of company size and the interest rate in the capital structure over six years (2013–2018) for 29 listed Pakistani enterprises operating in the sugar market. This research employed static panel analysis and dynamic panel analysis on linear and nonlinear regression methods. The capital structure included debt to capital ratio, non-current liabilities, plus current liabilities to capital as a dependent variable. Independent variables were profitability, firm size, tangibility, Non-Debt Tax Shield, liquidity, and macroeconomic variables were exchange rates and interest rates. The investigation reported that profitability, firm size, and Non-Debt Tax Shield were significant and negative, while tangibility and interest rates significantly and positively affected debt to capital ratio. This means the sugar sector has greater financial leverage to manage the funding obligations for the better performance of firms. Therefore, the outcomes revealed that the moderators have an important influence on capital structure.

This study aims to observe the long run and short run effects of gross domestic product, foreign direct investment inflows and trade on CO₂ emissions and causality relationships between these factors, using annual data for the period of 1974-2010. The empirical results demonstrate that the inverted U-shaped relationship of environmental Kuznets curve is valid for Turkey. In addition, there are positive long run effects of foreign direct investment and trade openness on CO₂ emissions. The authors also find a bidirectional causality relationship between CO₂ emission and FDI.

China’s involvement in Africa has become one of the contentious topics in the development literature. The background of the study is that Sino-African relations can be grouped into two phases thus: past relations and contemporary relations. The two phases are dissimilar, as past relations are categorized by solidarity against imperialism, while contemporary relations are characterized by economic relations. The study uses a historical approach to analyze China’s resurgence into Africa and Zimbabwe, a case study is used to examine the contemporary Sino-African relations. Secondary data were utilized to come to sound conclusion of the study. The study mainly found out that China’s resurgence into Africa presents both negative and positive impacts for Africa and that the negatives need to be regulated in order for African countries to benefit from the relations.
