In economics, elasticity measures how responsive an economic variable is to a change in another variable. An elasticity value greater than 1 implies that household income is elastic (i.e., more responsive). If the elasticity lies between 0 and 1, it means that household income is inelastic (i.e., not responsive). The full results of the elasticity analysis are presented in annex V and summarized below, in table 10. Given the same income levels (output) as agriculture, however, household incomes will be more responsive to investments in forestry and hunting than agriculture. Consider the case of forestry: forward linkages would exist if the growth of forestry led to growth in the pulp and paper manufacturing sector, which uses the output from forestry as its input.
