Recent raw material prices fluctuation has been unexpectedly high and that made Korean economic activities to be depressed. Because most raw material supply in Korea depends upon oversea imports, unexpected raw material price fluctuation affects Korean industrial economies through macroeconomic variables. So Korean government enforces some political measures such as demand management and the supply-security assurance as long-range policies, and reservation and general early warning system as short-range policies. In short-range policies, it is necessary to be expected short term fluctuation. Up to recently, there have been many researches and most of those researches use parametric methods or time series analyses. Because those methods and analyses often generate inadequate relations among variables, it is possible that some consistent variables are left out or the results are misunderstood. This study, therefore, is aim to mitigate those methodological problems and find the relatively appropriate model for economic explanation. So that, in this paper, by using non-parametric signal approach method mitigating some shortages of previous researches and forecasting properly short-range prices fluctuation of non-ferrous materials are presented empirically.

이번호에는 해외농산물 선물(先物)시장의 향후 가격 전망에 대하여 알아보겠다. 작년 한 해 농산물 가격은 연초 대비 지지부진한 상태가 계속되었으나 2010년 한 해에도 전세계 경기 회복세가 이어지면서 상승할 것으로 전망되고 있다. 다른 원자재품목대비 농산물 가격은 저평가되어 있기 때문이다. 하지만 2010년 수급상황이 호전되고 있어 농산물 가격 상승을 제한하는 요인으로 작용할 것으로 예상되는 바 가격 상승은 견조한 상승세를 이어갈 것으로 보인다.
