The relation of saving, investment, and consumption is given in this short article. We can also find out the relationship of interest rate and saving, consumption, and investment. The relation of average propensity of consumption and investment to marginal propensity of consumption and investment is also provided. This article explains why higher interest rate leads to less consumption, larger saving, and less investment.

Economic Decision-Making in the Ultimatum Game by Smokers.

Authors: Taiki Takahashi
Comments: 8 Pages.

OBJECTIVE: No study to date compared degrees of inequity aversion in economic decision-making in the ultimatum game between non-addictive and addictive reinforcers. The comparison is potentially important in neuroeconomics and reinforcement learning theory of addiction. METHODS: We compared the degrees of inequity aversion in the ultimatum game between money and cigarettes in habitual smokers. RESULTS Smokers avoided inequity in the ultimatum game more dramatically for money than for cigarettes; i.e., there was a "domain effect" in decision-making in the ultimatum game. CONCLUSIONS: Reward-processing neural activities in the brain for non-addictive and addictive reinforcers may be distinct and the insula activation due to cue-induced craving may conflict with unfair offer-induced insula activation. Future studies in neuroeconomics of addiction should employ game-theoretic decision tasks for elucidating reinforcement learning processes in dopaminergic neural circuits.
