Two-part trade policy in the reciprocal market model
No full textThis paper is devoted to the study of two-part trade policy for two countries, two markets, producers under imperfect competition, where the standard arguments of free trade are not applicable. The basic model is a two-step game with complete but imperfect information. The optimal policy of the government is analyzed in terms of the goals of maximizing the national welfare. This policy dominates over a simple quota and a simple tariff, which are its special cases. At the same time, the optimal two-part trade policy of governments that maximize national wealth is a subsidy
Sporadic radio emission of the Sun in the decametre range
No full textInternational audienceResults of the last observations of solar sporadic radio emission at the UTR-2 radio telescope (Kharkov, Ukraine) at the frequencies 10 - 30 MHz are presented. The use of new backend facilities, the DSP and 60-channel spectrometer, allows us to obtain data with time resolution up to 2 ms and frequency resolution of 12 kHz in the continuous frequency band 12 MHz. Usual Type III bursts, Type IIIb bursts, U- and J-bursts in the decameter range are discussed. Special attention is paid to detection and analysis of Type II bursts and their properties, newly discovered fine time structures of Type III bursts, Type III-like bursts, s-bursts, new observational features of drift pair bursts, and ‘absorption’ bursts
