A simple and implementable two-loop smoothing method for semi-infinite minimax problem is given with the discretization parameter and the smoothing parameter being updated adaptively. We prove the global convergence of the algorithm when the steepest descent method or a BFGS type quasi-Newton method is applied to the smooth subproblems. The strategy for updating the smoothing parameter can not only guarantee the convergence of the algorithm but also considerably reduce the ill-conditioning caused by increasing the value of the smoothing parameter. Numerical tests show that the algorithm is robust and effective.

A numerical method is proposed for solving a sort of constrained continuous minimax problem, in which both the objective function and the constraint functions are continuously differentiable about superior decision variables and are continuous about lower decision variables .Besides,the constraint functions include only superior or lower decision variables.The problem is transformed into unconstrained differentiable problem with the idea of the discrete maximum entropy function and the continuous maximum entropy function and the penalty function method.The basic algorithm is established.The convergence is proofed.Numerical examples are given and show the efficiency and the reliability of the algorithm.

After the financial crisis at the end of the 1990 s many countries rejected fixed exchange rate policy. However actually they failed to proceed to announced "independent float" exchange rate arrangement. This might be due to the "fear of floating" or an irreversible result of inflation targeting central bank policy. In the article advantages and drawbacks of fixed and floating exchange rate arrangements are systematized. Features of new returning to exchange rates stabilization and possible risks of such policy for Russia are considered. Special attention is paid to the issue of choice of a "target" currency composite which can minimize external inflation pass-through.

The Bank of Russia intends to introduce inflation targeting policy and exchange rate free floating regime in three years. Exogenous shocks absorption which stabilizes the real sector of economy is usually considered to be one of the advantages of free floating exchange rate policy. However, our research based on the analysis of 25 world largest economies exchange rates and industrial production during the crisis of 2008-2009 does not confirm this hypothesis. The article also analyzes additional risks associated with free floating exchange rate regime in Russia and presents some arguments in favor of managed floating exchange rate regime.

The level of trust in the local currency in Russia is very low largely because of relatively high inflation. As a result, Bank of Russia during crisis times can not afford monetary policy loosening and has to fight devaluation expectations. To change the situation in the post-crisis period Russia needs to live through a continuous period of low inflation. Modified inflation targeting can help achieve such a result. However, it should be amended with institutional changes, particularly development of hedging instruments.

The paper examines the impact of oil price shocks on inflation, as well as the impact of the choice of the monetary policy regime on the strength of this influence. We used dynamic models on panel data for the countries of the world for the period from 2000 to 2017. It is shown that mainly the impact of changes in oil prices on inflation is carried out through the channel of exchange rate. The paper demonstrates the influence of the transition to inflation targeting on the nature of the relationship between oil price shocks and inflation. This effect is asymmetrical: during periods of rising oil prices, inflation targeting reduces the effect of the transfer of oil prices, limiting negative effects of shock. During periods of decline in oil prices, this monetary policy regime, in contrast, contributes to a stronger transfer, helping to reduce inflation.

The paper presents an overview of studies of the effects of inflation targeting on long-term economic growth. We analyze the potential channels of influence, as well as modern empirical studies that test performance of these channels. We compare the effects of different variants of inflation targeting (strict and mixed). Based on the analysis recommendations on the choice of optimal (in terms of stimulating long-term growth) regime of monetary policy in developed and developing economies are formulated.
