Contagion effects in the world network of economic activities
πŸ‘€ V. Kandiah; H. Escaith; D. L. Shepelyansky

Using the new data from the OECD-WTO world network of economic activities we construct the Google matrix $G$ of this directed network and perform its detailed analysis. The network contains 58 countries and 37 activity sectors for years 1995, 2000, 2005, 2008, 2009. The construction of $G$, based on Markov chain transi…

Artificial Intelligence and Economic Theories
πŸ‘€ Tshilidzi Marwala; Evan Hurwitz

The advent of artificial intelligence has changed many disciplines such as engineering, social science and economics. Artificial intelligence is a computational technique which is inspired by natural intelligence such as the swarming of birds, the working of the brain and the pathfinding of the ants. These techniques h…

A General Equilibrium Theorem for the Economy of Giving
πŸ‘€ W. P. Weijland

In [1] we presented a model for transactions when goods are given away in the expectation of a later settlement. In settings where people keep track of their social accounts we were able to redefine concepts like account balance, yield curve and the law of diminishing returns. In this paper we establish a general equil…

Risk aversion in economic transactions
πŸ‘€ C. Anteneodo; C. Tsallis; A. S. Martinez

Most people are risk-averse (risk-seeking) when they expect to gain (lose). Based on a generalization of ``expected utility theory'' which takes this into account, we introduce an automaton mimicking the dynamics of economic operations. Each operator is characterized by a parameter q which gauges people's attitude unde…

Theories of Everything and Hawking's Wave Function of the Universe
πŸ‘€ James B. Hartle

If a cat, a cannonball, and an economics textbook are all dropped from the same height, they fall to the ground with exactly the same acceleration under the influence of gravity. This equality of gravitational accelerations of different things is one of the most accurately tested laws of physics. That law, however, tel…

Conditional heteroskedasticity in crypto-asset returns
πŸ‘€ Charles Shaw

This paper examines the time series properties of cryptocurrency assets, such as Bitcoin, using established econometric inference techniques, namely models of the GARCH family. The contribution of this study is twofold. I explore the time series properties of cryptocurrencies, a new type of financial asset on which the…

Integral representation of martingales motivated by the problem of endogenous completeness in financial economics
πŸ‘€ Dmitry Kramkov; Silviu Predoiu

Let $\mathbb{Q}$ and $\mathbb{P}$ be equivalent probability measures and let $ψ$ be a $J$-dimensional vector of random variables such that $\frac{d\mathbb{Q}}{d\mathbb{P}}$ and $ψ$ are defined in terms of a weak solution $X$ to a $d$-dimensional stochastic differential equation. Motivated by the problem of \emph{endo…

A review of the global climate change impacts, adaptation, and sustainable mitigation measures
πŸ‘€ Kashif Abbass; M. Qasim; Huaming Song; Muntasir Murshed; Haider Mahmood; Ijaz Younis

Climate change is a long-lasting change in the weather arrays across tropics to polls. It is a global threat that has embarked on to put stress on various sectors. This study is aimed to conceptually engineer how climate variability is deteriorating the sustainability of diverse sectors worldwide. Specifically, the agr…
