Consumption Models with Habit Formation

Habit formation

Habits, both good ones and bad ones, are pervasive in animal behavior. Important frameworks have been developed to understand habits through psychological and neurobiological studies. This work has given us a rich understanding of brain networks that promote habits, and has also helped us to understand what constitutes a habitual behavior as opposed to a behavior that is more flexible and prosp...

Utility Maximization with Addictive Consumption Habit Formation in Incomplete Semimartingale Markets

This paper studies the problem of continuous time expected utility maximization of consumption together with addictive habit formation in general incomplete semimartingale financial markets. Introducing an auxiliary state processes and a modified dual space, we embed our original problem into an auxiliary time-separable utility maximization problem with the shadow random endowment. We establish...

Solving Consumption Models with Habit Formation

The intuition for this equation is as follows. If λ, the parameter which controls how fast habits catch up with consumption, is equal to zero equation (6) reduces to the normal first order condition for the standard consumption optimization problem, which tells us that increasing consumption by today and reducing it by R in the next period must not change expected discounted utility. If λ is no...
