This study was conducted to investigate whether paddy cultivation in Malaysia do indeed contribute to increased CO2e. Johansen (1991) co-integration method was used to investigate the relationship between these variables, and the result clearly shows that they are highly co-integrated or literally means that they (both variables) share long term time trending patterns. The long run relationship is further investigated based on granger causality and vector error correction model (VECM), and the result again clearly shows that paddy production indeed granger causes the increased CO2e. Dynamic Ordinary Least Square (DOLS) method was also employed to check the robustness and consistency of the findings and the results are consistent and robust with the VECM estimations. The findings of the study clearly show the dire needs for the government to invest more on the R&D in the paddy production sector in order not to deteriorate further the environment albeit CO2e while securing the food security.

Economists recognized that exchange rate have a significant impact on trade. In this study we employed the Autoregressive Distributed Lag (ARDL) bounds testing procedure to analyze the impact of exchange rate on tomato’s export and import for Malaysia. The period of study covers 1997-2007 using quarterly data. Real Effective Exchange Rate (REER) was used rather than conventional exchange rate since this study covers the trade between Malaysia and the rest of the world. Our results indicate that both the export and import of tomatoes exhibit significant long-run relationships with REER. Causal effects in both cases are bidirectional. However, while the sign is economically correct for the relationship between REER and export, the same cannot be said for the relationship between import and REER.

This study was undertaken to explore the relationship between export and import, in the category of Forestry domain for Malaysia, which includes sub domain (1) industrial roundwood; (2) wood pulp; (3) wood fuel; (4) paper and paper board; (5) sawn wood; (6) recovered paper and (7) wood base panel. Johansen (1991) cointegration method was employed and the period of the study covers annual data from 1961 to 2007. The results clearly show that the export and import of forestry domain is highly cointegrated. This shows trade is indeed sustainable in the domain of forestry and a sign of good trade policies adapted and implemented by the relevant authorities Bi-directional granger causality could also be detected based on VECM (vector-error correction model) method. Imports seem to positively and significantly affect exports, both in the long run and short run, vice versa.
