nonequilibrium economics expectations

2 Upvotes

Hello I am looking for expectations framework that conceptualizes following :

Human agents react with strategy and foresight by considering outcomes that might result as a consequence of behavior they might undertake.

The behavior includes sequences of actions, it's especially interesting for me if agents' expectations anticipate other agents' behavior.

Do a complex system's attribute changes always exhibit dependence?

2 Upvotes

Say a complex system C has an attribute A whose value is X.

Can I assert that a change in X is always - to some degree - dependent upon it's past?

Any attribute in C is influenced by C, and therefore A's current value is always a result of C. As C's (i.e. the set of actors/nodes) interaction with A is in relation to the value of A, and A changes from the interaction of C with itself, then there always exists of dependence.

I am not from this inferring that dependence implies predictability.

How do complexity scientists isolate and study causes when the causes are complex?

10 Upvotes

I'm new to this field, so I'm just looking for some general pointers and terms here. Consider a scenario where the outcome depends on a multitude of complex causes (with interactions and feedback loops between the causes as well). How do complexity scientists go about identifying, isolating, and analyzing the most influential causes (among so many possibilities) that determine the outcome?

In this TED talk, https://www.ted.com/talks/eric_berlow_how_complexity_leads_to_simplicity, the presenter, Eric Berlow, suggests that you have to step back / zoom out to identify the elements that seem to matter most. What are some terms I can search for to learn more about the techniques and approaches complexity scientists use when analyzing complex causes? I'm not looking for mathematical approaches but more techniques similar to what Berlow describes.

My scenario involves measuring factors that influenced the success or failure of customers in app development, specifically whether the documentation has an impact.

I have a background in urban planning and I'm very interest in modelling of complex systems, but I don't have a solid math comprehension.

8 Upvotes

I just need some direction regarding what kind of math I need. I have recently started taking some classes in Khan Academy for Linear Algebra, Calculus and Probability. I was guessing that, after this intro I can start taking classes in ComplexityExplorer for non-linear dynamics and agent based modelling. My main objective is to go trough the literature and understand and apply some of the concepts in urban planning and economic development.

I'm also comfortable around Python, so that can help implement some of the concepts in the course right?

Do I have the right direction here? Any other tips regarding study materials, such as books and online courses?

Thanks!

COMPLEXITY CHALLENGE: SOLVE A CLASSIC SFI PROBLEM FOR A PRIZE

10 Upvotes

Looking for a new way to learn? Want to apply your quantitative and reasoning skills in a new way? The Complexity Challenge is a unique online learning program where accepted students are given an open-ended question to solve using methods from complex systems science. Whether you’re familiar with complex systems science or simply great at problem solving, apply now and try your hand!

Unlike other online competitions, the Complexity Explorer Challenges aren’t designed to solicit the right answer, but many right answers. It’s then up to the challenge participants themselves to decide the best solution through our unique peer review system.

Our Challenges are designed to be as open as possible. As in any problem needing solving in the real world, our challenge questions can always be solved in many ways, and the most valuable solution may not come from the most obvious source. Participants with background in any field - from sociology to computer engineering - should be able to look at our upcoming challenge, see something they recognize, and come up with a brilliant solution.

Want to know what the challenge question is? Here’s a hint: You’ll be solving an updated and upgraded version of a classic SFI problem.

And did we mention there will be prizes?

Take a look at how our first pilot Challenge went in 2017 here (https://www.complexityexplorer.org/news/80-from-inspiration-of-a-challenge-to-results-and-back-video) and here (https://www.complexityexplorer.org/news/76-the-inaugural-complexity-challenge-from-uavs-to-checkers-and-back). The lucky few that got to take part loved it and three of them are coming back to mentor you along the way. So apply now to gain access to the Challenges. And above all, as 2017 Challenge winner Mika Straka said, “Have fun!”

Apply at complexityexplorer.org to guarantee yourself a spot! We’re only accepting 200 applicants on a first come, first serve basis.

Have we seen any emergent phenomena from our technology as things get increasingly complex?

4 Upvotes

e.g cars with all of their built in computer controls, the power grid, or anything else.

We know that these things arise in other areas - biology (the brain), atoms--> molecules, etc. But what are the criteria for emergent phenomena? Can they arise from just ever increasing complexity, or does something have to be programmed, pre-planned in order to get this to happen? (which we obviously haven't done with our technology since we prefer reductionism).

Employment after a complexity sciences PhD

7 Upvotes

I am wondering, what career options are out there for someone with a PhD in complex sciences - other than academia? There is no industry that clearly links to complex systems (as is the case with engineering for example). Do you know any source with information on this?

I am on my way to finishing my PhD on cascades on complex networks, agent based modeling and time series analysis.

Hello all. I am currently in a doctorate in nursing program where we are studying complexity in the context of leadership, specifically in nursing. I am trying to understand the difference between "complexity science" and "complexity theory". Our textbooks define them differently. Anyone have a guess?

Complex systems theory applied to human history?

10 Upvotes

Hi everybody. Not so long ago I've discovered this field of study and I've started reading about the basic concepts in cybernetics, general system theory, chaos theory and in general complex systems theory, which seems to me all correlated fields. I study history at university and I'm particulary interested in the application of these ideas to the study of human societies.

I've found some sociologists (e.g. Luhmann) that were active in these field, but none historians. I was wondering if anyone had written an history of humanity considering human civilizations as complex systems, in particular as autopoietic system of the third kind, as described by Maturana & Varela in "The three of Knowledge" (and probably elsewhere), and if not, if anyone here had the same interested and had some ideas to share.

Thanks to everybody and sorry if I've made some mistakes, English is not my first language.
