Health Economics

  • (written as Time)
    Time plays at least four distinct roles in economics. First, it enters most economic functional relationships either because one is considering rates of consumption (e.g. of drugs per week) or rates of inputs (e.g. so many X-ray machine hours per year) or rates of enjoyment of particular states (e.g. such and such a state of health for one year) or because one is considering entities at a particular point in time, such as stocks of health. Second, time enters explicitly as a factor in intertemporal choice theory, concerning the optimal pattern of consumption, investment, or the use of a resource over time. Third, time is used to classify 'runs' in production theory, as in short run and long run. Fourth, time is itself a kind of resource having opportunity costs and it can be either efficiently or inefficiently utilized; thus, patient's time is an inherent part of many processes of healing, as it is frequently an inherent part of gaining access to health care (waiting).


  • noun hours worked by a person


  • noun the period that is needed for something to take place, e.g. one hour, two days, fifty minutes

Origin & History of “time”

Time originally denoted ‘delimited section of existence, period’. Its ultimate source is the Indo-European base *- ‘cut up, divide’. this passed into prehistoric Germanic as *- (source also of English tide), and addition of the suffix *-mon- produced *tīmon – whence English time and Swedish timme ‘hour’. The application of the word to the more generalized, abstract notion of ‘continuous duration’ dates from the 14th century.
