Background: In the most studies, differentiation of two issues: purchase quantity and willingness to purchase has not been considered. The purpose of this study was to eliminate the error caused by non-separation of these two issues.
Methods: Data were extracted from the raw data of the rural household expenditure and income survey plan of 2019. For removing sampling bias due to the low share of buyers of medicinal plants for treating in the society, the two-stage Heckman model was used countrywide.
Results: Based on the estimation results, for every ten million rials increase in drug cost and income, the willingness to pay for medicinal plants increases by 200 and 800 rials, respectively (P <0.01). Also, the presence of medicinal plants in the region and access to physicians increases the consumption of medicinal plants by 2.7 and 1.4%, respectively (P <0.01). But time and age of head of household had no significant effect at this level. The marginal effect indicated the location conditions of families (in terms of access to medicinal plants and treatment) are more effective than social and economic variables on behavior of people's willingness to buy medicinal plants. After estimating purchase function and calculate the elasticities, it turned out, medicinal plants are a normal commodity.
Conclusion: The results showed that the variables affecting the choice of medicinal plants are different from the factors affecting of consumption of these products in terms of type and amount of effect. |
