The author presents the results of the discovery in Marx's works of the disparate elements of the theory of the original transformation of value into prices and the establishment of the general rate of profit. These results show:(a) Marx's tables in Chapter 9 of Volume III of Capital do not represent the usual interrelated branches of the economy, but particular spheres of production, exempt from the double-counting of profits and wages, and producing only final commodities. The total value of these commodities is equal to the net social product.(b) Marx carried out the original transformation of values into prices under the condition that wages remain unchanged. As a result, the first (chief) macroeconomic equality is fulfilled—the sum of the production prices for all net social products must be equal to the sum of its values. Also is fulfilled the second macroeconomic equality—the sum of profits of all sectors forming separate spheres of production must be equal to the sum of surplus values.(c) Marx assumed that the original transformation takes place in two stages: in the first stage, average rates of profit are formed in separate spheres of production, comprising two sectors of production: A and B. Sector A produced of constant capital for the sphere's own need. Sector B releases the final product for an exchange with other particular spheres. In the second stage, is established the general rate of profit in sectors B. A property of the original conversion is some change in the level of real wages, especially noticeable when using numerical models with a few spheres of commodity production. Therefore, Marx introduces the hypothesis of mutual compensation of positive and negative deviations of prices from the values of commodities. The hypothesis is fully confirmed under the conditions of the law of large numbers.(d) Marx also explains that non-equilibrium original prices of production, in which demand and supply of final goods do not coincide, can be transformed into equilibrium prices of production. For this to happen, corresponding changes in monetary wages, prices of constant capital, and the general rate of profit are necessary. However, the attainment of equilibrium prices was regarded by Marx as a secondary issue. At equilibrium prices, only the first (chief) macroeconomic equality is fulfilled.The author in developing alternative methods of transforming value into original and equilibrium prices of production uses all of the above elements of the theory of transformation of values into production prices. First, he restores the double counting of profits and wages in Marx's table. Second, he applies an iterative procedure of sequentially establishing the average and general rate of profit in the sectors and spheres of commodity production.The paper proposes new iterative calculation algorithms in the Excel program for the original and equilibrium transformation of values into production prices. The author tested the algorithms using the Wolfram Mathematica software. He also developed a method for converting the equilibrium production prices of goods back to their initial absolute values. This method refutes the well-known “eraser algorithm” by P. Samuelson. Ultimately, the author argues that Marx does not have the errors of transformation that his critics have attributed to him for so long.

This chapter focuses on situations of pure exchange, where consumers wish to exchange bundles of goods they hold at the outset for other bundles they will subsequently consume. It uses this setting to introduce the theory of price-mediated market transactions and, more particularly, the theory of general equilibrium, in which all markets in all goods are considered simultaneously. Following in the footsteps of generations of classical microeconomists, the chapter makes the assertion that in many situations of pure exchange, the consumer will wind up at the consumption allocation part of some Walrasian equilibrium for the economy, and insofar as there are markets in these goods, prices will correspond to equilibrium prices. One thing that the concept of a Walrasian equilibrium does not provide is any sense of how market operates. There is no model here of who sets prices, or what gets exchanged for what, when, and where.

Chapter 5 focuses on producers’ net worth. It joins a large strand rooted in the financial literature, which points out that under asymmetric information, producers need own equity to obtain credit. Incorporating this assumption yields scenarios with endogenous borrowing limits and shows that small variations in credit requirements have large macroeconomic consequences. A second theme concerns an unresolved problem of general equilibrium models. These determine equilibrium prices from decisions of producers and consumers who are ostensibly aware only of market prices and their own characteristics, i.e., technologies and preferences. However, consumers must also know current profits because these enter their budget constraints. As profits are determined in equilibrium, a logical circle emerges. Stock manias can be interpreted as situations where consumers overestimate profits; conversely, stock market crashes may reflect underestimations of profits. The text shows that misguided profit expectations as such do not have the expected impacts on economic activity.

This article is an overview of the contribution made by economic Sovietology to mainstream economics. The long debate about the universal applicability of mainstream economics is reconsidered in the light of the Soviet experience. Information is provided on the contribution of the study of the Soviet economy to fields as diverse as the measurement of economic growth, institutional economics, economic administration, the economics of property rights, the economics of the informal sector, the economics of famines, the Austrian critique of general equilibrium theory, and incentives.
