 note = {Technical Report, Within a fully continuous dynamic framework, in which health is assumed to deteriorate uncertainly with age, the optimal level of health at which the individual decides to see a doctor as well as to which the individual improves his health by obtaining medical treatment will be characterised. It will be shown that as long as the cost to keep obtaining medical treatment during a certain period of time is strictly positive, there will always be a finite period during which the individual does not require medical treatment, and that under a certain condition an increase in medical expenditure induces the individual to see a doctor more frequently than before if the increase in medical expenditure is not caused by an increase in the cost which depends on the individual health level. It will also be shown that the effects of an increase in uncertainty and aging population on the optimal frequency to see a doctor depend on time preference, the trend and the volatility of the process of health deterioration., 滋賀大学経済学部Working Paper Series, No. 65, pp. 1-38},
