Economic Model Building and Computers in Forestry Research
Although most past research in forestry economics was characteristically descriptive in nature, recent research is more diagnostic. Formal model building is used more extensively when diagnostic studies are undertaken. Models are classified as: (1) either verbal or mathematical; (2) within mathematical models - either deterministic or econometric; (3) microeconomic or macroeconomic; (4) static, comparative static, or dynamic; and (5) within dynamic models, either continuous or discrete dynamic. Steps in the model building process are indicated, with emphasis on the interrelations between the steps, feedbacks, and the division between the real and symbolic worlds. Criteria for testing adequacy of models partly depend on the model type. The role that data processing equipment can play in each stage of the model building process is pointed out. A computer can be a fundamental tool in the research process, best understood as an integral part of the model building process.
