Bubbles and Overshooting Crash
This paper reviews a model of bubbles under the assumption of heterogeneous rational traders. In the presence of dispersion of opinions, or sequential awareness, financial bubbles are justified by the interactions between rational arbitrageurs and behavioural traders. Timing is a very important component in the trader's strategy. This model is then extended to explain both bubbles and overshoot...
متن کاملOvershooting dynamics in a model adaptive radiation.
The history of life is punctuated by repeated periods of unusually rapid evolutionary diversification called adaptive radiation. The dynamics of diversity during a radiation reflect an overshooting pattern with an initial phase of exponential-like increase followed by a slower decline. Much attention has been paid to the factors that drive the increase phase, but far less is known about the cau...
متن کاملPolicy oscillation is overshooting
A majority of approximate dynamic programming approaches to the reinforcement learning problem can be categorized into greedy value function methods and value-based policy gradient methods. The former approach, although fast, is well known to be susceptible to the policy oscillation phenomenon. We take a fresh view to this phenomenon by casting, within the context of non-optimistic policy itera...
متن کاملOvershooting convection in tropical cyclones
[1] Using infrared satellite imagery, best-track data, and reanalysis data, tropical cyclones are shown to contain a disproportionate amount of the deepest convection in the tropics. Although tropical cyclones account for only 7% of the deep convection in the tropics, they account for about 15% of the deep convection with cloud-top temperatures below the monthly averaged tropopause temperature ...
متن کاملHydrodynamical model atmospheres and 3D spectral synthesis
1 Radiation-hydrodynamics modeling – overview In this paper we discuss three issues in the context of three-dimensional (3D) hydrodynamical model atmospheres for late-type stars, related to spectral line shifts, radiative transfer in metal-poor 3D models, and the solar oxygen abundance. To establish the context we start by giving a brief overview about the model construction, taking the radiati...
