- Signaling, Prior-bias and Welfare
Implications
Eunjee Joo, Yong-Ju Lee
Although most economics and social science textbooks describe
Bayes¡¯ rule as the basic principle of probabilistic inference
combining prior information with additional information from new
observations, it is widely observed in the laboratory experiments
that people¡¯s information processing systemically deviates from
Bayes¡¯ rule. Here we illustrate how receiver¡¯s prior-biasedness
affects players¡¯ strategic incentives and welfare implications in the
¡°costless¡± and ¡°costly¡± models of signaling. From these examples
we draw an interesting welfare implication that the receiver¡¯s
prior-bias may work as a welfare-enhancing device even in the
costly signaling environments. That is, contrary to the widespread
beliefs that non-Bayesian inference is a sign of human irrationality
and a social cost, we show that a behavioral bias can be beneficial.

- Impact of Photovoltaic Generation Expansion
on Korea's Electricity Power System and the
Solutions: Focusing on Power System
Stability and Supply-and-demand Stability
Wan-soo Kim, Ha-Hyun Jo
To achieve the GHG reduction target, various eco-friendly
policies are implemented by countries. The expansion of renewable
energy is one of the most important policies in many countries
including Korea. In order to cope with the unstable supply and
demand and the system unstable due to the photovoltaic
generation, it is necessary to consider securing flexible resources,
discovering artificial inertia, and securing auxiliary services. Also,
the introduction of a multi-layered trading system, the reduction
of transaction time-units, the separating the reserve market from
the energy market, and the granting the solar self-responsibility
obligation should be concerned as a solution.
