In this broad-ranging book, Eric Beinhocker defends a vision of the economy as a complex adaptive system. The theory that explains the operation of the economic system he calls Complexity Economics. The Origin of Wealth is a frontal attack on Neoclassical economic theory. Beinhocker recognizes the successes of this theory, but locates them in the past. The combined aridity of classical game theory, in which there have been no new insights for almost twenty years, and general equilibrium theory, which has produced nothing of ...

Abstract: The aim of this paper is to sketch a strategic map of some of the relevant issues at the intersection of economics, sociology and evolu-tionary theories of development. The unit of evolution is taken from psychological personal construct theory. Methodologically, a successful integration of these areas requires a transfer of complexity and non-linear methods and development of further measurement methods in the complexity area.
The model that ths paper sets out is based on a combination of the Schumpeterian creative destruction and the neo-Austrian notion of market process. It gives a formalization of the succession innovation-structural organization and its endogenous mechanism, crucial to explain economic growth and development. More in particular, the essay gives an explanation of innovation, endogenous uncertainty and describes the way equilibrating and disequilibrating processes are intertwined and operate. It also shows that a representation of this dynamic competition process cannot do without some appropriate development on entrepreneurship and its links with uncertainty. Finally, some simulations with the proposed model are provided.

The Emergence of Innovation Complexity at Different Geographical and Technological Scales2019 •
We define a novel quantitative strategy inspired by the ecological notion of nestedness to single out the scale at which innovation complexity emerges from the aggregation of specialized building blocks. Our analysis not only suggests that the innovation space can be interpreted as a natural system in which advantageous capabilities are selected by evolutionary pressure, but also that the emerging structure of capabilities is not independent of the scale of observation at which they are observed. Expanding on this insight allows us to understand whether the capabilities characterizing the innovation space at a given scale are compatible with a complex evolutionary dynamics or, rather, a set of essentially independent activities allowing to reduce the system at that scale to a set of disjoint non interacting sub-systems. This yields a measure of the innovation complexity of the system, i.e. of the degree of interdependence between the sets of capabilities underlying the system's ...
The city of Kolkata is under the appalling shadow of carbon dioxide rise since few decades. Rapid urbanization coupled with the plying of large number of vehicles and congested roads have enhanced the grim situation of the city atmosphere. The present study aims to portray the air quality of the city considering near surface atmospheric carbon dioxide as indicator during two different situations, namely COVID-19 complete lockdown phase in 2020 and COVID-19 partial lockdown phase in 2022. This study was carried out around 10 major healthcare units in the city to assess the spatio-temporal variation of carbon dioxide. Our results exhibit significant variations between sites as well as the two lockdown phases of COVID-19 (p < 0.01), which may be due to degree of closure of the anthropogenic activities in context to COVID-19 lockdown.

À travers l’étude des découvertes monétaires effectuées dans deux agglomérations portuaires du nord de l’Italie, Gênes et Aquilée, cet article a pour objectif de comprendre la circulation monétaire dans le contexte très spécifique des installations portuaires. Plaques tournantes des biens et des moyens d’échange, zones de concentration des métiers marchands et de banques, l’analyse de l’économie de ces installations portuaires permet de mieux comprendre l’organisation des échanges monétaires durant l’Antiquité. Les sites de Gênes et d’Aquilée possèdent la particularité d’être situés sur deux côtes opposées de l’Italie septentrionale : la côte ligure donnant sur la mer Tyrrhénienne et la côte adriatique. Une comparaison avec les installations portuaires de Narbonne, Lattes, Pouzzoles et Délos complète ces données économiques relatives aux sites portuaires ouverts sur la Méditerranée.
