The welcomed introduction of Fred Moseley to a 27-page excerpt from Marx's Economic Manuscript of 1867–1868 draws attention to the influence of turnover times on the formation of prices of production. This chapter discusses the profit-adjustment decomposition outlined by Marx in these pages where he tries to distinguish the influences of turnover time and capital composition on the formation of the prices of production. It provides an alternative decomposition based on Marx's analysis in the second volume of Capital and argues that these pages do not support Moseley's claim that prices of production are intended only to describe a long-run equilibrium condition. It therefore suggests considering the profit adjustment in relation to the dynamic formation of the general rate of profit throughout the equalization process.

This chapter introduces Marx's theory of the determination of profit rates. It contrasts this theory with what happened in the late nineteenth century to British profit rates with a detailed statistical account. It identifies missing features in the standard presentation and contrasts these with the overaccumulation hypothesis that he presents elsewhere. A formal mathematical model using the overaccumulation hypothesis is then given and tested against modern empirical data.

Considering that the rate of profit constitutes a key indicator for the analysis of the evolution of capitalist economies, this chapter proposes to study the case of France from 1896 to 2019, that is, over 124 years in total. From a series of stock of productive capital reconstructed for the occasion, a rate of profit is calculated at the macroeconomic level within a conceptual framework faithful to Marx. Over this period of more than a century, three successive long waves are identified, as parts of a secular trend toward the fall in the French rate of profit. The latter, however, recovered several times during these three subperiods, but finally reoriented downwards, with fluctuations of an amplitude tending to decrease more and more and a deployment in a decreasing spiral of French capitalism. This long-term downward trend is mainly due to the rise in the organic composition of capital.

This chapter analyzes the process of surplus generation in Latin America based on the Penn World Tables, also with a comparison with the United States. The reference period is 1950–2019, revealing long-run evolution as well as certain differences between a State-driven industrialization strategy, the turn toward neoliberalism beginning in the 1980s, and a neo-developmentalist period in the twenty-first century. The research shows a steep decline in the rate of profit in Latin America until the early 1990s, with stabilization thereafter but without reversal of the downward trend. However, the turning point in terms of capital accumulation, surplus generation, and productivity indicators occurred in the early 1980s. In addition, divergence vis-à-vis the United States has been growing in the capacity to generate surplus, labor productivity, and GDP per capita.

In recent years, some peer-to-peer (P2P) service sharing platforms have improved their service quality by setting an entry quality threshold for service providers. Considering consumers' heterogeneous preferences for service quality and commission rate, it is worth studying how to select the commission rate contract for a P2P platform under a predetermined entry quality threshold for service providers.

In this study, the platform's profit-maximizing model is constructed under two proposed contracts: unilateral commission rate contract and bilateral commission rate contract. The optimal entry quality threshold and the optimal commission rate are obtained. This study also explores the impacts of cross-side network externality and service price on a platform's optimal decisions and social welfare.

Results show that it is always advantageous for the platform to adopt the bilateral commission rate contract, which is closely related to the strength of cross-side network externality, service price and quality sensitivity coefficient. Under certain conditions, adopting the unilateral commission rate contract can reduce platform profit and service provider surplus, and improve consumer surplus and social welfare.

This study analyzes the unilateral commission rate contract and the bilateral commission rate contract of the platform, and discusses which contract is beneficial to the platform, consumers and service providers. In addition, this study provides a basis for the operation decision of a P2P service sharing platform and the pricing decision of service providers.

The objective of the study is to explore the determinants of savings and their relative importance in Saudi Arabia.

The stationarity of the data has been tested using augmented Dickey–Fuller (ADF) tests. Autoregressive distributed lag (ARDL) technique has been applied to establish the long run and short run relationships. Stability of savings function has been tested by applying CUSUM and CUSUMSQ techniques.

Results of ARDL identify the important factors affecting savings behaviour in Saudi Arabia. According to the results, the growth rate of GDP, the interest rate, foreign direct investment (FDI) and budget surplus positively affect savings with the last two having the most influence on domestic savings. The coefficient of the dependency ratio is negative in conformity with the theory. Similarly, the coefficient of the inflation rate is also negative.

There is limited availability of data since only 41 years’ annual data are available.

In the light of the results, it is recommended that in order to increase savings, the government should adopt policies to attract FDI, increase the GDP growth rate and decrease the dependency ratio and inflation.

Government needs to discourage larger family sizes to encourage savings in the light of the result of negative impact of the dependency ratio on savings. In order to decrease the dependency ratio, more family members especially women should be encouraged to participate in the labour market.

There is a scarcity of research for Saudi Arabia on the critical issue of determinants of domestic savings. This is a pioneering study exploring important determinants of savings in Saudi data.

To explore how the blockchain affects the pricing and financing decisions in a low-carbon platform supply chain.

Considering the dual roles of the e-commerce platform as a seller and an initiator, a typical game-theoretical method is applied to analyze the behavior of supply chain decision-makers and the impact of key variables on equilibriums.

When loan interest rates are symmetric, whether blockchain is used or not, the e-commerce platform financing mode will always produce higher wholesale price and unit carbon emission reduction, while the retail price is the opposite. Higher unit additional income brought by the blockchain can bring higher economic and environmental performances, and the e-commerce platform financing mode is superior to bank financing mode. The application of blockchain may cause the manufacturer to change his/her financing choice. For bank financing, with the increase of loan interest rates, the advantages brought by blockchain will gradually disappear, but this situation will not occur under e-commerce platform financing.

Blockchain is known for its information transparency properties and its ability to enhance user trust. However, the impacts of applying blockchain in a low-carbon platform supply chain with different financing options are not clear. The authors examine the manufacturer's strategic choices for platform financing and bank financing, whether to adopt blockchain, and the impact of these decisions on carbon emissions reduction, consumer surplus and social welfare. The research conclusion can provide reference for the operation and financing decisions of platform supply chain under the carbon reduction target in the digital economy era.
