Factors Influencing the Changes of Forest Cover (a Case Study on Sumatra Island)

In Indonesia, decreasing the forest cover or deforestation in 2000-2005 period had increased up to 1,09 million ha per year, and in Sumatera island alone the deforestationreached 0,27 million ha per year. The primary factors that caused the changes of forest cover in Sumatera are logging, both legal and illegal, and forest conversion for other landuses. This paper used panel data model for eight provinces in Sumatera from 2000 to 2006 to analyze direct causes of changes of forest cover. In the model of changes of forest cover caused by logging, resulted a positive correlation between deforestation and price of timber. These results implied that the rise of timber price made illegal loggers try to get maximum profit in a short time, and it could stimulate illegal logging. In the model of changes of forest cover caused by forest conversion for other land uses, the results showed a positive correlation between deforestation and GDP per capita. The result concludes that the increase of GDP per capita makes consumption for agricultural goods increase, and it can stimulate forest conversion for other land uses

Term Structure Examination of Indonesian Money Market: Some Efficiency Issue

This paper examines efficiency of Indonesian term structure as imposed by the country\u27s central bank. The rate, widely understood as the Bank Indonesia (BI) Rate varying from 30-day, 60-day, and 180-day, usually stated as the plain-vanilla cost of capital of interbank debt financing depending on their time length. In general, this rate will consequently impact various other sorts of interest rates in the country\u27s debt market as a whole. When dealing with market efficiency, statistical inference shows that short-term BI Rate\u27s is not the best predictor of its long-term one due to some uncertain asymmetric information. This finding may lead to further adjustment in risk management strategy for hedging with interest rate
