Week 2 Flashcards
Logical positivism
Its a philosophy of science. Logic: provide the formal framework (language) in which the scientific claims are best to be put. All human knowledge of the world is amenable to logical formalization. In the formal logic we just name something a claim a ‘proposition’and assign a value to it (true or false, 1 or 0).
Positivism: all scientific evidence and thus knowledge is directly or indirectly derived from sensual date. Science is characterized by the ability to formulate theories.
Analytics
1 + 1 = 2. the truth 2 is already included in the premises 1 + 1. Given the assumptions of the Ricardian model, international trade is mutually beneficial.
Synthetic
Confirmed by empirical research (deductive)
As the emprical research demonstrates, people value an object higher when they do not posses it.
empirically verifiable
you can verify whether it is true or false by drawing gon sense perception
Deduction
Goes from the general to the specific
Induction
Goes from the specific to the general.
operationalization
Going from the theoretical statements to the observational statements. The operationalization is making theoretical statements observational statements. How do you make your theory testable in the empirical word.
Problem with induction.
Even if all the swans we have observed so far are white, there might appear another swan, which is black!
Inductive differences
Two or more instances of an event (effect) are compared to see what they all do not have in common. If they have all but one thing in common, that one thing is identified as the cause.
Method of ceteris paribus
keeping everything else the same. This is used for models and to use your mind as a laboratory. Deduction from the abstraction of home economics.
Universal Laws
Whenever X, Y. But universal laws hold only under quite specific conditions.
Economics laws could be thought of as tendency laws: regularities that are true in the abstract,
but contaminated by various disturbances in the real world.
Tendency claims
Claims about a regularity that would hold if disturbing factors were absent. This means that laws are unviersallyt rue if not interpreted literally (not as actual phenomena) but as descriptions of tendencies.
What is a tendency
Tendencies are causes like MV=PT, changes in M cause changes in P. Causal factors fully operating only in the absence of disturbing factors like given the high rate of innovations, the rise in M could
even decrease P! Causal factors still operating even in the presence of disturbing factors (but perhaps
not fully visible). Even if P decreases, it decreases less than without the increase in M
composition of causes
simply add up all the forces (causal factors) that influence our behavior and pull it in different directions. The sum of different tendencies.
Which science is closer to economics?
Engineering and medicine. (evidence based approach, experimental approach, the way you test drugs we test economic theories.
