Time-Stability Of The Coefficients: An Input-Output Analysis On Romania Case

A country’s economy involves complex input-output (IO) structures of goods and services. The IO models, important instrument for economic and forecasting analysis, provide a reliable back-ground for scientists of structural economic changes acting under the influence of various factors. In this paper, the IO method was used to test the time-stability of technical coefficients using the IO sta-tistical tables for 2000 and 2006 years. The main conclusion is that the IO method can be used as a quantitative and qualitative instrument for analysis on short and medium term (not more than five years).
