Фондовый рынок: современное состояние, инструменты и тенденции развития. Девятая Межвузовская научная конференция, Москва, 12 апреля 2012
The general issues of determining the liquidation value are discussed, such as the choice of market liquidity risk model and the choice of a price benchmark for estimating transaction costs. The layout for the portfolio management process is proposed which is grounded on a previously developed approach to determining the liquidation value of a portfolio. It allows not only defining and linking the rational liquidation strategies for different time horizons but also considering some microstructural effects, such as volatility momentum, corresponding to the intervals between trading sessions.
One of the key questions in financial mathematics is the choice of an appropriate model for the financial market. There are a number of models available, such as Geometrical Brownian motion, different types of Levy processes and more general semimartingale models. As the model passes from the simple to the more general, it gains in its ability to model real data but loses computational tractability. The goal of this paper is to present a semimartingale model for which we can carry out computation of the optimal equivalent martingale measure, and which still retains the capacity to model processes with history-dependent increments. Since the inclusion of jump processes in the model leads to incomplete markets, we obtain the “best” equivalent martingale measure according to a number of popular criteria and show how these criteria are associated with particular choices of utility or distance functions.
In this paper we study convergence among Russian regions. We find that while there was no convergence in 1990s, the situation changed dramatically in 2000s. While interregional GDP per capita gaps still persist, the differentials in incomes and wages decreased substantially. We show that fiscal redistribution did not play a major role in convergence. We therefore try to understand the phenomenon of recent convergence using panel data on the interregional reallocation of capital and labor. We find that capital market in Russian regions is integrated in a sense that local investment does not depend on local savings. We also show that economic growth and financial development has substantially decreased the barriers to labor mobility. We find that in 1990s many poor Russian regions were in a poverty trap: potential workers wanted to leave those regions but could not afford to finance the move. In 2000s (especially in late 2000s), these barriers were no longer binding. Overall economic development allowed even poorest Russian regions to grow out of the poverty traps. This resulted in convergence in Russian labor market; the interregional gaps in incomes, wages and unemployment rates are now below those in Europe. The results imply that economic growth and development of financial and real estate markets eventually result in interregional convergence.
The paper examines the structure, governance, and balance sheets of state-controlled banks in Russia, which accounted for over 55 percent of the total assets in the country's banking system in early 2012. The author offers a credible estimate of the size of the country's state banking sector by including banks that are indirectly owned by public organizations. Contrary to some predictions based on the theoretical literature on economic transition, he explains the relatively high profitability and efficiency of Russian state-controlled banks by pointing to their competitive position in such functions as acquisition and disposal of assets on behalf of the government. Also suggested in the paper is a different way of looking at market concentration in Russia (by consolidating the market shares of core state-controlled banks), which produces a picture of a more concentrated market than officially reported. Lastly, one of the author's interesting conclusions is that China provides a better benchmark than the formerly centrally planned economies of Central and Eastern Europe by which to assess the viability of state ownership of banks in Russia and to evaluate the country's banking sector.
The paper examines the principles for the supervision of financial conglomerates proposed by BCBS in the consultative document published in December 2011. Moreover, the article proposes a number of suggestions worked out by the authors within the HSE research team.
