Game-Theoretic Perspectives on Financial Crises

Abstract: Global financial crises have revealed the systemic risk posed by economic contagion. We provide perspectives on the formulation of a game between countries, central banks, banks, firms, households, and financial intergovernmental organizations to model the dynamics between players. We model strategic choices, strategy sets, and utility functions to provide new tools to handle financial crises. The model is illustrated with examples using sensitivity analysis. One country, and two countries, are considered, and we simulate the impacts of random shocks under a variety of assumptions. #neuroeconomy #beavioral_economy

The mortality of companies

The firm is a fundamental economic unit of contemporary human societies. Studies on the general quantitative and statistical character of firms have produced mixed results regarding their lifespans and mortality. We examine a comprehensive database of more than 25 000 publicly traded North American companies, from 1950 to 2009, to derive the statistics of firm lifespans. Based on detailed survival analysis, we show that the mortality of publicly traded companies manifests an approximately constant hazard rate over long periods of observation. This regularity indicates that mortality rates are independent of a company's age. We show that the typical half-life of a publicly traded company is about a decade, regardless of business sector. Our results shed new light on the dynamics of births and deaths of publicly traded companies and identify some of the necessary ingredients of a general theory of firms.Madeleine I. G.

2 Jones Lakeshia's curator insight, January 14, 4:45 PM

the short film starts off as if you've clicked the wrong link and you have no idea how this accidentally got here however the video becomes interesting. The sweet alpacas demonstrate income inequality, All the alpacas set out to start their first jobs. The first alpaca, happy, was automatically granted a six figure job in a laid back area due to her fathers status. The second alpaca went to engineering school and was granted a low income job. The last alpaca wasn't even granted a job due to her not going to a fancy school. The video connects to AP gov. because the three alpacas were much like the trend of the economy and market over the years. One's views could be altered because how the economy works is revealed in a negative yet truthful way. The information could indeed be categorized as reliable due to its depth of explanation and several examples.

Introduction to the Modeling and Analysis of Complex Systems

Introduction to the Modeling and Analysis of Complex Systems introduces students to mathematical/computational modeling and analysis developed in the emerging interdisciplinary field of Complex Systems Science. Complex systems are systems made of a large number of microscopic components interacting with each other in nontrivial ways. Many real-world systems can be understood as complex systems, where critically important information resides in the relationships between the parts and not necessarily within the parts themselves. This textbook offers an accessible yet technically-oriented introduction to the modeling and analysis of complex systems. The topics covered include: fundamentals of modeling, basics of dynamical systems, discrete-time models, continuous-time models, bifurcations, chaos, cellular automata, continuous field models, static networks, dynamic networks, and agent-based models. Most of these topics are discussed in two chapters, one focusing on computational modeling and the other on mathematical analysis. This unique approach provides a comprehensive view of related concepts and techniques, and allows readers and instructors to flexibly choose relevant materials based on their objectives and needs. Python sample codes are provided for each modeling example.http://textbooks.opensuny.org/introduction-to-the-modeling-and-analysis-of-complex-systems/

The retail market as a complex system

Aim of this paper is to introduce the complex system perspective into retail market analysis. Currently, to understand the retail market means to search for local patterns at the micro level, involving the segmentation, separation and profiling of diverse groups of consumers. In other contexts, however, markets are modelled as complex systems. Such strategy is able to uncover emerging regularities and patterns that make markets more predictable, e.g. enabling to predict how much a country’s GDP will grow. Rather than isolate actors in homogeneous groups, this strategy requires to consider the system as a whole, as the emerging pattern can be detected only as a result of the interaction between its self-organizing parts. This assumption holds also in the retail market: each customer can be seen as an independent unit maximizing its own utility function. As a consequence, the global behaviour of the retail market naturally emerges, enabling a novel description of its properties, complementary to the local pattern approach. Such task demands for a data-driven empirical framework. In this paper, we analyse a unique transaction database, recording the micro-purchases of a million customers observed for several years in the stores of a national supermarket chain. We show the emergence of the fundamental pattern of this complex system, connecting the products’ volumes of sales with the customers’ volumes of purchases. This pattern has a number of applications. We provide three of them. By enabling us to evaluate the sophistication of needs that a customer has and a product satisfies, this pattern has been applied to the task of uncovering the hierarchy of needs of the customers, providing a hint about what is the next product a customer could be interested in buying and predicting in which shop she is likely to go to buy it.

With this knowledge and insight into the world that's dawning.  One world must be destroyed in order for the new world to come forth; one segment of society must give way to the new in order to facilitate and ease this transition.

 

The top of society is where and what determines the ease or the possibility of this transition.  That is the point that needs to be altered in order to bring about this new dawn.  

 

Unfortunately, it is the point in society that is least willing, although most capable of change.  They'll cling to illusions and delusions of relative power over people and unsustainable material wealth than allow for everyone, including themselves, to realize something that could truly be wonderful for our lives, our well-being, and our health as living organisms.  This is before we talk about the bottom-up resistance that will be experienced as well, especially if the transition is done badly by the people who are at the top of the given social unit.  A shame that something so relatively simple can be so completely complicated and complex to carry out.

 

Silly world.

An Idealized Design for the Legislative Branch of Government | Systems Thinking World Journal

An Idealized Design for the Legislative Branch of Government | Systems Thinking World Journal | Computational Economics | Scoop.it
This paper presents an idealized design for a legislative system. The concept of idealized design is explained. The paper critiques two critical (and often taken for granted) features of the legislative branches of most contemporary democratic governments: legislators are chosen by election, and the same bodies perform all legislative and meta-legislative functions, for all laws. Seven problems with these two features are described. A new model of lawmaking is proposed, based on three concepts from ancient Athenian democracy — random selection, dividing legislative functions among multiple bodies, and the use of temporary bodies (like contemporary juries) for final decision making. The benefits of the model are laid out, and likely objections are addressed.

Coding on campus and beyond - McGill Daily

Though it may be true that we are moving toward a society where computer science knowledge will be as integrated as math and English in the primary school system, coding literacy is even more important for university undergraduates as they prepare for the competitive, technologically advanced, and evolving job market. It’s difficult for students to make sense of the hype around computer science, programming, and ‘hacking.’ Long-standing barriers between technical and non-technical folks create misunderstandings that conceal the true breadth of technology and its essential applications across all academic fields. University students should be encouraged to harness the potential of programming to expand opportunities in their fields. Even beyond practical usage, coding provides an alternate way of thinking. Employing logic through the mind of a computer forces rationality, brevity, and accuracy. Strong leaders harness interdisciplinary critical thinking by considering problems from within different mindsets (creative, mathematical, emotional, etectera) to form an optimized solution.
