We define an asset exchange model by adding the kickback rate to the trade, and discuss the Gini index with different kickback rates. It is found that for every kickback rate, the related Gini index tends to be steady; thus, the kickback rate — Gini index curve may be obtained. Furthermore, it is shown that the Gini index decreases when the kickback rate increases, so that the fair degree of social wealth distribution gets better. The Gini index reaches a minimum when the kickback rate is 0.58, and then it increases, as the accretion of the kickback rate destroys the fair degree of social wealth distribution. However, in all situations, the Gini index with kickback rate is less than the one without kickback. This means that the introduction of kickback rate is favorable to the raising of the fair degree of wealth distribution. We also define a moral index similar to the Gini index to weigh the differences of social moral level, and find that the differences of social moral level increase with time for the model with kickback rate.

AbstractIn this paper, I review several dust evolution studies based on the DustPedia nearby galaxy sample. I first present the dust spectral energy distribution model, implementing a hierarchical Bayesian method, that we have developed. I then discuss the dust evolution trends we have derived among (integrated) and within (resolved) galaxies. In particular, we show that the trend of dust-to-gas ratio with metallicity is clearly non-linear, indicating the need for grain growth in the interstellar medium. Our trend is closer to the one derived with damped Lyα systems than what was suggested by previous studies. We finally demonstrate the universal processing of small amorphous carbon grains by stellar photons.

AbstractThis contribution analyses the viability of the new Spanish financial landscape which has been drawn by the European authorities and the national administration in order to overcome the progressive deterioration of social wealth in Spain since the beginning of the economic crisis in 2008.The adoption and the implementation of a new legal framework during the last two years, establishing tougher requirements on capital adequacy, leverage ratios and counter-cyclical and other buffers, as well as the shaping of the Banking Union, are not enough to transform the Spanish banking system into the key tool for the creation of wealth.There is a paradox of both legal and institutional outcomes. While, on the one hand, some positive changes in the functioning and the structure of the banking industry have been prompted by the regulatory reform, there are, on the other hand, some uncertainties linked to the recapitalisation costs of a relevant group of credit institutions and the persistence of serious structural problems of the Spanish economy.Moving faster to full banking union will reduce financial market stress in Spain.

The wealth substitution rate, which describes the substitution relationship between agents’ investment in wealth, is introduced into the collision kernel of the Boltzmann equation to study wealth distribution. Using the continuous trading limit, the Fokker–Planck equation is derived and the steady-state solution is obtained. The results show that the inequality of wealth distribution decreases as the wealth substitution rate increases under certain assumptions. The wealth distribution has a bimodal shape if the wealth substitution rate does not equal one.

The early twentieth-century oil boom radically transformed the Osage reservation in Oklahoma, and in the early 1920s the Osages became the world's richest community because of their collective sharing of profits from mineral resources. In 1934, John Joseph Mathews, an Osage American tribal historian, publishedSundown, his only work of fiction, a peculiarBildungsromanabout the life of Chal Windzer in the aftermath of oil discovery on the Osage reservation. I argue that Mathews's use of the novel of formation is a particularly important literary and intellectual intervention. First, at a time when the significance of material resources to the American economy and American national imaginary was growing, Mathews uses the generic convention of progress to narrate oil's social “formation,” alongside the tale of Chal's dissolution, his failure, that is, of the very development which the novel's genre implies. Second, Mathews's literary representation of the oil boom as the Great Frenzy – a period of widespread violence and cultural chaos – complicates traditional accounts of capitalist economic development, which define late-stage capitalism and its financial deregulation and IT boom as an era of radical cultural “fluidity” (Bauman, Sennett). By drawing attention to the material and social fluidity of oil culture and the force with which it affected the Osages,Sundownpoints to a specific Osage American colonial, and thus always already transnational, history of (petro)modernity. The character of modernity, Mathews shows us, is inextricably tied to the conditions under which human and natural resources are extracted and allowed to become “social.” The destabilization of reservation culture derives equally from oil discovery itself, and the technological transformations within the energy industry, from the colonialist conditions that impose capitalism upon the Osages, and from the very collectivist modes of wealth distribution that the Osages adopted in order to resist colonial exploitation. Thus Mathews's novel reveals an alternative genealogy of the destabilization of cultural forms to the one that begins with post-Bretton Woods global financial deregulation, the collapse of state institutions in the global North, and the late twentieth-century emergence of new communication technologies. For the Osages in the 1920s and for the characters inSundown, crude oil and colonial exploitation, as well as, paradoxically, anticapitalist legal provisions of the Allotment Act's collectivizing of it, make reservation culture “liquid” and “uncertain” precisely at the time of America's entering into the presumably “solid” econo-political phase of development.
