Ch.7 Value Measurement Flashcards
causal claim
any assertion that invokes causal relationships between variables, for ex- ample, that a drug has a certain effect on preventing a disease.
Causal inference
involves drawing a connection between two states of affairs and inferring that one caused the other.
causal claim extra info
One problem is that an event may have a number of causes that together bring it. Another issue is that an event might have causes that can bring it about separately on different occasions.
The problem is that causal connections can be very complicated, and figuring them out can be difficult.
Finally, an event might have countervailing causes—causes that prevent the effect from occurring. For instance, smoking can cause cancer, but it does not cause it necessarily because individuals might be doing other things (exercise?) that reduce the impact from tobacco. Therefore, not every smoker develops cancer.
Correlation is not a guarantee of a causal connection.
Correlation is not a guarantee of a causal connection.
to establish a causal connection
you need to establish if there is co-variation between the vents—if A event happens then the B event happens, and if A event does not happen, the B event does not happen.
One can determine co-variation through
experimentations where all variables are controlled (held constant), allowing variation only for the alleged cause and effect.
Temporal priority
event A (the alleged cause) always precedes event B (the alleged effect).
Covariance
The two events must vary together; as one varies (e.g. increases or decreases), the other also varies (increases or decreases).
Assessing Causal Arguments
Temporal Priority
Covariance
A reasonable mechanism should be conceivable that enables the causal relation between two events.

A key point in finance is the time value of money, which states that purchasing power of one unit of currency can vary over time. Finance aims to price assets based on their risk level and their expected rate of return.
