POS Rational Choice Theory CH7 Flashcards
What is rational choice theory a combination of?
Individualism and explaining
Individualism in rational choice theory
- causal accounts of social phenomena provide an explanation of how they originate from the actions and motivations of individual agents
- does not allow for trait-based differences across individuals, thus differences are not based on traits; all observed behavioral differences are explained situationally through incentives. This means they do not stem from the actors
Explanatory model in rational choice theory
- to explain behavior and social level outcomes (e.g. institutions) from rational choices of individual agents
- aimed at discovering rules or laws that generalize towards other comparable situations
Assumptions to explain social phenomena in accordance with the rational choice theory
- methodological individualism:
- Individuals are perfectly rational (all options considered, transitivity (order of options), all knowledge)
- Agents are fully self-interested
Dual ambitions: both positive (explaining) and normative (justificatory)
What is methodological individualism?
Ontological individualism:
- only individual natural person really exists
- social phenomena do not really exists (they are aggregate outcomes of the actions and behaviors of individuals
Methodological individualism:
- social phenomena (rules, structures, institutions) really exist, but we can explain them only from the actions and behaviors of individual human beings.
–> contrast with the functional and systems explanation that explains social phenomena from from other social phenomena (Durkheim)
Two ways of an individual to be rational
Parametric rationality
Strategic rationality
Parametric rationality
- assumption is that the choices of others are known in advance (given parameters for a decision)
Strategic rationality
- additionally to parametric rationality takes into consideration the rational choices of other agents, who in turn take into consideration and try to anticipate your actions
–> the situation is one of interdependent choices
Popper and the rational choice theory
- it is a bad theory because it does not contain any empirical content.
- if you only look at it from your own point of view, you cannot exclude anything
Positive theory and world fit
- says something about what the world is like
- if there is a difference between the actual world and the theory then the theory needs to be adjusted.
Normative theory and world fit
- says something about what the world should be like
- if there is a difference btw. theory and world the world needs to be adjusted.
- we should follow a theory and act accordingly
metering problem
hard for any principle to monitor the agent’s actions to gather the necessary information
adverse selection
Adverse selection is when sellers have information that buyers do not have, or vice versa, about some aspect of product quality.
Moral hazard
- when agents take on mare risk than they should, because the costs are carried by the principal and not by the agent
Holdup
the agent and principle could work a lot more efficiently together if they would cooperate.
