Pasture productivity and the capacity to make hay rose more slowly (at least in the upland areas) and farmers partly replaced cows with goats (the ‘poor man’s cow’). The goats’ activities, combined with the growing fuel demands of the expanding population, seriously degraded mountain forests (Pfister, 1983). By the early 19th century, highland population growth had led to both environmental degradation and pauperization (Pfister and Messerli, 1990). Thus the introduction of potatoes in Switzerland suggests that the technological change might have had a negative effect on the forest.

Innovations that are intensive in the scarce factor will reduce deforestation. Adding more realistic features to the model may modify these results. For example, we have assumed that farmers cannot substitute between different inputs. However, in reality, farmers may find ways to relax their capital constraint by substituting labour for capital. If they do, the new technology will not necessarily reduce deforestation. The new capital-intensive technology may also help the farmers become eligible for credit or persuade them to request more credit, thus removing their capital constraint and allowing them to expand their area.
