Impact Assessment Flashcards
What factors are involved in a disease impact assessment? How can these be split?
1) Direct - Visible losses e.g. dead animals, thin animals, Invisible losses e.g. fertility problems.
2) Indirect - Additional costs e.g. medicines, vaccines, Revenue foregone e.g. Sub-optimal use of technology.
What does economic logic tell you?
Where Avoidable Losses are greater than Costs of a Change in Disease Status
the investmentis worthwhile
What are avoidable losses?
Losses that can be avoided with intervention.
What does a partial budget analysis compare?
The additional benefits against the additional costs.
What is information on disease impact used for?
To prioritise diseases.
What is a negative externality?
The livestock livestock owner with FMDhas a negative negative impact on those connected to their herd or flock as the disease is likely to spread
What is a positive externality?
Where a livestock owner protects their animals from FMD they will generate a positive externality as they will be protecting the animals of livestock owner who are connected to the protected population.
What is opportunity cost?
The sacrifice of one alternative for another.
How do you calculate productivity?
Productivity = Total value of outputs per unit of time/Total value of inputs per unit of time
What are marginal costs and benefits?
These costs are those that are additional to an activity and are associated with a change. These benefits are generated by a change and are also additional.
What four factors is partial budget analysis interested in?
Costs - 1) New costs 2) Revenue foregone
Benefits - 3) Costs saved 3) New revenue
What is revenue foregone?
Revenue foregone isthe income that is sacrificed by making a change and relates to the “opportunity cost” of the change.
What is revenue foregone?
Revenue foregone is the income that is sacrificed by making a change and relates to the “opportunity cost” of the change.
