The "loss of "wellbeing" in the context of an asthma sufferer's health is an another way of stating that such a person is not in a healthy state, wellbeing being another way of referring to a person's good health in this context. Since the economic loss suffered by the asthma sufferer is stated to be $200, we must assume that this is an enumeration of the economic loss that he/she has suffered from loss of income (perhaps the person has been unable to do his/her job), with incidental expenses of an asthmatic condition amounting to, in this example, a financial loss of $100.
Is the OP sure that these amounts are not $200 million and $100 million respectively, in which case we are dealing with the US economic consequences of asthma at State or Federal level?
