Initially it is interesting to know that there exists a model which can do it but once several alternative models become available then a different criteria is needed to choose between them. Many pieces of research claim to have successfully “explained” some event or phenomenon or to allow the economists to “understand” some situation. An an analogy, consider being given a new piece of electronic equipment and a book of instructions. After reading the instructions a person may claim to understand them but the proof will occur if that person can actually use the equipment correctly, or as promised when it was originally obtained.

The main policy variable for controlling this activity at this time is the building of new roads. What should occur next is a cost/benefit analysis of a policy that encourages or discourages deforestation. A number of development economists attempt such calculations although they are inherently uncertain, as it is difficult to know the potential value of plant or insect species that have not yet been studied and which could have medical or biochemical benefits to mankind in the future, for example.

As is usual with such regressions, some results are considered “sensible” and not surprising – such as demand decreasing with distance from the federal capital – some results might be considered surprising – demand increasing as neighboring areas clear more land – and some results are disappointing – the “policy variables” not coming into the model significantly. It follows that the model cannot be used directly in its present form to consider the effects of policy changes. 3, which is taken from Andersen (1997), is part of a system and it is found that one of the inputs to ⌬CLRt, the growth in urban outputt has SUDAM credittϪ1 as a significant input, and so it is seen that 23 Empirical Modeling in Economics policy does have a two-stage and positive effect, resulting in an increase in demand for newly cleared land.
