Note. This table presents: G2 -probability ratio; df - degrees of freedom; Sig - observed significancelevel; coefficients estimating the linear connection (association) of theranges of each factor with the actual changes of finished stock volumes, andstandard errors (SE).

The current changes in demand did have theexpected signs. They produced reverse changes of finished stock, i.e. thegrowth of sales volumes in Russian industry is accompanied by decreasingwarehouse stock volumes. Thus, demand in part is satisfied at the expense ofaccumulated stock, while some of the unsold products remains as stock. Thismechanism of utilizing stock has become especially obvious lately when thecoefficients reached their maximum negative values and turned out to be moreand more often statistically significant. Before the 1998 default nosignificant values of these coefficients were obtained. The current changes ofcosts have positive but statistically insignificant influence on the changes offinished stock. Consequently, Russian industrial enterprises prefer to usetheir stock more as a buffer to level off sudden demand changes than as abuffer for smoothing cost changes. Again we wish to emphasize that theseconclusions refer to the current changes of demand, costs and finished stockonly.
