Ebook Fertility and Economic Crisis: Inflation, Wage Devaluation and Job Instability in Russia
Submitted by puput on Fri, 02/19/2010 - 03:55The fall of the Soviet Union initiated an era of unparalleled political and economic reform given the breadth, depth and speed of the changes. The shift towards democracy and capitalism entailed greater personal freedom of thought, expression and lifestyles. The dismantling of the command economy allowed competition to flourish, thus improving productivity of the individual as well as the firm. Overall, individual well?being should have been enhanced through increased freedom and economic resources. However, in Russia and many other countries that underwent market reform, the transition was accompanied by economic crisis, which decreased well?being through material hardship and insecurity. Populations that had never dealt with extreme social risk suddenly found themselves unemployed, unpaid or unable to cope with inflation, while lacking a sufficient safety net and watching the “winners” of the transition achieve unprecedented wealth.
Undoubtedly, these complicated transformations greatly influenced demographic decisions, including whether and when a child was desired. Indeed, while the majority of men and women had two children in Russia before 1990, fertility fell to below 1.2 children per woman by the end of the 1990s (Zhakarov and Ivanova 1996). Research on this dramatic decline has shown very little relevance of postponement to the majority of this fertility decline, nor does it appear due to increasing childlessness rates; the decline seems to be due to stopping behavior in which second and higher order births declined (Sobotka 2002).

Ebook A Least-Squares Mixed Finite Element Method For Biot’s Consolidation Problem In Porous Media
Submitted by wulan on Thu, 03/18/2010 - 08:48In recent years, a lot of effort has been dedicated to the theoretical and numerical treatment of models for fluid flow and deformation in porous media. Our model will be based on the classical phenomenological approach by Biot [2] using the concept of effective stresses. Modern formulations based on multiphase mixture theories were developed in the last 30 years, see the monograph by de Boer [12] for an overview. A lot of current research activity concerned with the numerical treatment of such coupled problems is devoted to the extension to two-phase flow and elasto-plastic deformation models.
The classical Biot consolidation problem assumes a fully saturated porous medium and a linearly elastic material law leading to a linear parabolic system. We restrict our attention to this linear problem since our aim is to analyze a least-squares mixed finite element method in the simplest possible situation. The novelty of our least-squares approach is the introduction of approximation spaces for the fluid flux and the stress tensor in addition to the primary variables fluid pressure and displacement field.

Ebook The Bank of Japan’s Approach to Liquidity Risk Management in Financial Institutions
Submitted by puput on Wed, 11/04/2009 - 03:37The turmoil in global financial markets since the summer of 2007 has again highlighted the importance of liquidity risk management in financial institutions. This paper clarifies the relationship between liquidity risk in financial institutions and a central bank’s policy and operations, and then describes the Bank of Japan’s approach to liquidity risk management. This paper aims at contributing to the further improvement in risk management in Japanese financial institutions and to international discussions on liquidity risk management.
What makes liquidity risk management in financial institutions difficult is the fact that where the risk lies and how significant it is cannot necessarily be assessed from the figures on the balance sheets. Factors that trigger the manifestation of liquidity risk lurk in all the areas of financial institution management, and the way of manifestation and the size of liquidity risk can vary according to the business model and its surrounding environment. Thus, in considering liquidity risk management, it is important to take into account a broad range of factors associated with liquidity.
