  • We find that dynamically consistent (exponential) impatience cannot explain the magnitude of the decline. The model needs either an implausibly large degree of annual impatience, or a very large intertemporal elasticity of substitution. Intuitively, the problem arises because the exponential discount rate is constant over time:1 even a mild degree of short-run discounting, say a daily discount rate of 1 percent, implies a daily discount factor of 0.99 and thus an annual discount factor of 0.99365 = 0.03.

  • The quantum theory is the first theoretical approach that helps one to successfully understand the atomic and sub-atomic worlds which are too far from the cognition based on the common intuition or the experience of the daily-life. This is a very coherent theory in which a good system of hypotheses and appropriate mathematical methods allow one to describe exactly the dynamics of the quantum systems whose measurements are systematically affected by objective uncertainties.
