This study deals with the structural interrelationships among agricultural sub-sectors, and between the agricultural and non-agricultural sectors of the West Virginia economy. The study is intended to offer information on which to base sound economic development decisions. An input-output economic model is used in order to focus on the interaction between agricultural production and other sectors of the state economy. The major findings are: (1) a $1 million change in commodities sales at the farm level translates into an average change of $2.9 million in the state's total output of goods and services; (2) a $1 million change in gross farm income yields an average change of $2.2 million in statewide income; (3) every 100 jobs created in the agricultural production sector stimulates 295 total jobs in the state economy; (4) the crop production sub-sectors have larger output and employment multipliers, on average, than those for livestock production, although the livestock production sub-sectors have larger average income multipliers; (5) the agricultural production sub-sectors showing high impact on the state economy include dairy products, food and feed grains, and fruit and nut trees; and (6) input-output coefficients from this study reflect high degrees of interdependence among agricultural production sub-sectors and between the agricultural sector and other sectors of the economy. The paper includes three tables showing cash receipts from farm sales, sectors and their components, and input-output multipliers for different sectors. Includes 11 references. (TES)
