Mutual exchange

The timescale is just one sub-classification of chemical exchange. It can be further divided into coupled versus uncoupled systems, mutual or non-mutual exchange, inter- or intra-molecular processes and solids versus liquids. However, all of these can be treated in a consistent and clear fashion. 

Transamidation and Transesteramidation. Transamidation is the mutual exchange of chain fragments in a polyamide, shown as follows where R, R" and R, R" represent polymer chain fragments of any length. 

From the NMR spectra of MeiSnCli solutions recorded at different values of pH, considering the known species distribution of hydroxo complexes in fast mutual exchange, it is possible to calculate the individual NMR parameters 6, )... 

The I.G. was a great factor in German commercial pohcy. A statesman once coined the words, "Without the I.G. and without coal, I can have no foreign pohcy." We were always concerned with a mutual exchange of experiences and aims.. . . Since the first World War I beheved that in international science and understanding lay the solution to the economic illnesses of Europe and Asia. 

There are two main ways in which reproduction is made possible. First, the two departments have complementary requirements. Department 2 exchanges 2,000 units of its output of consumption goods for 2,000 emits of means of production produced by Department 1. These 2,000 emits of con-seimption goods fulfil the variable capital (1,000) and capitalist consumption (1,000) requirements of Department 1. And the 2,000 units of means of production supplied by Department 1 allow capitalists in Department 2 to replace used-up constant capital. Reproduction is facilitated by mutual exchange between the two departments. 

The key difference is that Department 1 produces 6,000 units of capital goods, but only 5,500 are required to replace constant capital in the two departments.3 Department 2 now requires 1,500 units of capital goods in order to replace the amount it uses up. But Department 1 continues to produce a surplus of 2,000 units of capital goods (equivalent to 1,000 variable capital plus 1,000 surplus value) over and above the 4,000 it needs to replace constant capital. Therefore, the mutual exchange that took place between the two departments under simple reproduction, where surplus consumption goods were swapped for surplus capital goods, is only partially fulfilled. Marx (1978 587) explains that in each period of production the surplus of capital goods produced by Department 1 remains to be realized .4... 

The circulation of money in Nell s model has some resemblance to Marx s analysis of mutual exchange between departments of production, as discussed in Capital, volume 2 (Marx 1978 474-8). Marx provides a similar example in which capitalists in the capital goods sector (Department 1) advance a sum of 1,000 to workers. He writes ... 

The most basic proportions embedded in the reproduction schema are established under simple reproduction. This was touched on in our introduction to the schema in Chapter 2, and in establishing the mutual exchange which takes place between departments of production in the circulation of money (Chapter 4). These proportions can be formally derived, in Table 6.1, by displaying the elements of Marx s numerical example (Table 2.1) alongside the Marxian algebraic symbols.3... 

First, a mutual exchange theory of money is formulated. Money first comes into circulation by the payment of wages (Luxemburg 1951 94). Capitalists in Department 1 advance 1,000 units of money to their workers as variable capital. Capitalists in Department 2 sell consumption goods to Department 1 for this value of 1,000 units. The money, first advanced in Department 1, circulates into the hands of capitalists in Department 2. With the money received from this transaction, Department 2 s capitalists are able to purchase means of production from Department 1 and the money returns into the hands of the Department 1 capitalists. The same type of mutual exchange happens for the 500 emits advanced as variable capital in Department 2. 

Luxemburg therefore identifies the Kalecki principle in Marx s reproduction schema if the capitalists themselves have set in motion all the money which circulates in society, they must also advance the money needed for the realization of their own surplus value (ibid. 98). Under simple reproduction, this money is earned from the extraction of surplus value in previous periods, but in the current period of production capitalists clearly earn what they spend (the Kalecki principle). So long as there is sufficient money cast into circulation for capitalist consumption, together with the mechanism of mutual exchange, all goods are sold in the market place. Under simple reproduction, as summarized by Howard and King (1989 107), There is no deficiency in the demand for either department s output, and no reason why production should not continue at this level in later periods. ... 

Although it is traditional in Marxian frameworks for capitalists to initiate the circulation of money with an advance of constant and variable capital, our previous discussion, in Chapter 4, showed that there are a number of ways in which the circulation of money can be modelled. In the single swap approach all of income is advanced in the Franco-Italian circuit approach only the wage bill is advanced in Nell s mutual exchange approach only wages in the capital goods sector are advanced. Our contribution has been to suggest, under the Kalecki principle (first introduced in Chapter 3), that capitalists advance an amount of money sufficient to realize their profits. This model is predicated on the definition of investment as accumulation of constant and variable capital. 

See Chapter 4 for a detailed discussion on the roles played by mutual exchange and the Kalecki principle in Capital, volume 2.

The US FDA and the European Union have held regular bilateral meetings for the last decade to discuss common areas of interest. This has involved mutual exchange of guidelines for consultation.
