On the Dynamics of Informatization of the Russian Market of Precious Metals

In June 2012,the UN conference on sustainable development "Rio+20" summarized the work of the world community in this direction for last 20 years and outlined the tasks for the future.The UN website contains enough information to estimate the importance of global problems and "green economy," taking into account a very complicated state of the global and Russian markets which are balancing on the verge of crisis.Unfortunately,the website does not contain the materials of the 6th civilization forum "Long-Term Strategy for Sustainable Development on the Basis of Partnership of Civilizations:Concepts,Strategy,Programs and Projects" within the bounds of "Rio+20" which has considered the problems of a dialogue and partnership in conditions of extensive globalization.These problems are covered in the Partnership of Civilizations Journal which is issued in the Russian,English and Arabian languages,including its Internet version.The International Informatization Academy (it has the general consultative status at the Economic and Social Council of the UN) and its 20-year activity in the sphere of informatization of the world and Russia on the way to the partnership of civilizations,are presented there[1].

Dynamics of the Austrian Food Market: Application of Lotka-Volterra Differential Equations

The organic food market has become an important part of food industry. We analyze sales data from Austria for 2014 to 2020 of 124 products from 25 product groups in six categories, each in conventional and organic form. We fitted their market shares by means of a modified Lotka-Volterra model with constant coefficients. When only organic and conventional products were compared, a significant increase in market shares was observed for 15 of 25 organic product groups, indicating a continuing growth of the organic food market. The typical Lotka-Volterra dynamics was a predator-prey dynamics with an organic product (group) predating on conventional products that were in symbiosis.

Labor Market Dynamics and Structural Change： Evidence from China

Structural change theories usually assume agents are homogeneous. However, because of demand-side or supply-side heterogeneities, the probability of switching among sectors differs across people. This paper reveals these differences through restoring a long-period, individual-level panel dataset from China＇s Urban Household Survey for 1986-2009. We find that both for people who started working for the first time and those who switched jobs, the sector choice depends on personal characteristics. In particular, women and people with higher educational attainment or a previous white- collar job are more likely to join the tertiary sector and less likely to join the primary sector. These effects are substantial even if the macroeconomic variables used in conventional structural change theories are controlled. They are also robust in various periods and at more detailed industry levels. Our research suggests that it is important to pay greater attention to the labor composition when mal^ng policy related to economic structural change.

Sequential First-Price Auction with Randomly Arriving Buyers

In this paper we reanalyze Said’s(2011) work by retaining all his assumptions except that we use the first-price auction to sell differentiated goods to buyers in dynamic markets instead of the second-price auction. We conclude that except for the expression of the equilibrium bidding strategy, all the results for the first-price auction are exactly the same as the corresponding ones for the second-price auction established by Said(2011). This implies that the well-known "revenue equivalence theorem"holds true for Said’s(2011) dynamic model setting.
