Measuring the Value Added by Money in Trade

The paper tests the proposition that money generates value in trade. It examines the data for 5,746 Russian companies for 1997 and finds that money accounts for 24.6 percent of their value-added. The functional form of the return on money in trade is determined to be positive and marginally declining. The paper imputes that Russian GDP lost 8.1 percent in 1997 because of diminished use of money in trade. It hypothesizes that the severity of the Great Depression in the USA of 1930s could have been significantly reduced if the proposed barter networks were implemented at the time.http://deepblue.lib.umich.edu/bitstream/2027.42/40021/2/wp635.pd

Effective Tax Rates in Transition

The paper addresses the question of effective tax rates for Russian economic sectors in transition. It presents a detailed account of fiscal environment for 1995 and compares statutory obligations with reported tax liabilities. The paper finds that taxation did not contribute to recession, as some observors believed at the time. It extends research by questioning the role that inflation played distorting revenue structure. When the costs of intermediate inputs are adjusted for inflation, many sectors have negative residual revenue, which is indicative of recession. Yet, modeling tax changes to correct the situation does not produce positive results, for the tax share in the cost structure of many sectors is small and cannot compensate for inflationhttp://deepblue.lib.umich.edu/bitstream/2027.42/39762/3/wp378.pd

Normal frames for linear connections in vector bundles and the equivalence principle in classical gauge theories

Frames normal for linear connections in vector bundles are defined and studied. In particular, such frames exist at every fixed point and/or along injective path. Inertial frames for gauge fields are introduced and on this ground the principle of equivalence for (system of) gauge fields is formulated.Comment: 20 standard LaTeX pages.
