Hua-Chen New Theory of Economic Optimization [PDF]

open access: yesarXiv
Between 1957-1985, Chinese mathematician Loo-Keng Hua pioneered economic optimization theory through three key contributions: establishing economic stability's fundamental theorem, proving the uniqueness of equilibrium solutions in economic systems, and developing a consumption-integrated model 50 days before his death.

A Theory of Chaordic Economics: How Artificial Intelligence and Blockchain Transform Businesses, Economies and Societies [PDF]

open access: yes
Dee Hock, the founder of Visa, coined the term 'chaordic' to describe simultaneously chaotic and ordered systems. Based on his reasoning, we introduce the Theory of Chaordic Economics to explain how economic systems are transformed by two disruptive technologies: namely Artificial Intelligence and Blockchain.

Low‐Surface‐Energy Copper Promotes Atomic Diffusion and Ordering in PtFeCu Intermetallic Compounds for Oxygen Reduction Catalysis

open access: yesAdvanced Functional Materials, EarlyView.
A copper‐induced atom ordering strategy is developed for the reconstruction of raw commercial Pt catalyst into ordered PtFeCu intermetallic compounds for hydrogen fuel cells. Abstract Carbon‐supported platinum intermetallic compound nanoparticles are seen as the next‐generation cathodic catalysts for hydrogen fuel cells due to their high activity and ...

Technology and economic theory

open access: yesCambridge Journal of Economics, 2009
Technology and technological change play a central role in economics, whether in the theory of resource allocation or in the theory of growth and development. Yet the nature of technology is largely ignored in economic theory, it being considered sufficient to treat technology as a constraint on productive opportunities.

Economics of information and the theory of economic development [PDF]

open access: yesBrazilian Review of Econometrics, 1985
This paper shows how recent developments in the economics of information can provide insights into economic relations in less developed countries, and how they can provide explanations for institutions which, in neoclassical theory, appear anomalous and/or inefficient.

From Sicilian mafia to Chinese "scam villages" [PDF]

open access: yesarXiv, 2019
Inspired by Gambetta's theory on the origins of the mafia in Sicily, we report a geo-concentrating phenomenon of scams in China, and propose a novel economic explanation. Our analysis has some policy implications.

Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

open access: yesAdvanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.
