COMPARISON OF GROSS OUTPUT AND FINAL DEMAND OF INDUSTRY AGRICULTURE, HUNTING, FORESTRY IN THE BALTIC STATES AND FINLAND

The actual scientific problem of national economy arising from practical managerial needs is to discover the implicit inter-industry marginal relations between components of the net output and components of the gross output of industries taking in account revenues and expenditures of industries. The goal of this paper is to highlight the application possibilities of the input-output analysis for theoretical investigations and for managerial needs. Methodical innovation the marginal analysis under selected ceteris paribus constraints in various mixed forms is offered. In order to demonstrate the offered method in action, as the object of the research the industry “Agriculture, hunting, forestry” in Estonia, Latvia, Lithuania and Finland was selected. The mathematical tool of the offered method is the Gauss-Jordan elimination or pivot transformation of the linear systems derived from the input-output model, which allows to calculate large sets of marginal economic indicators. It should be noted that each number in these linear systems contains important economical information that could be useful for comparative statics and managerial decision making. Some of marginal indicators discovered trough the offered input-output analysis are well-known and already used traditionally, but for all that thanks to pivot transformation realized in the various mixed forms create new indicators that usually are not immediately apparent in simple linear systems but are revealed step by step.
