Could you expand on this? There is a lot of reasoning as to why the Equilibrium theory is so prevalent in economics.

What's to expand on? There is absolutely no empirical evidence to support the notion that prices tend toward equilibrium in any time frame. There is, however, evidence to show that prices are reflexive; they are in a constant state of change or fluxuation and tend towards trends.

Of course you will.

>This is a normative statement not a positive one.
You have that backwards. The empirical evidence (the observable reality) is that prices constantly change and tend towards trends, not reach an equilibrium. The only which could be viewed as having a tendency toward equilibrium is securities as they relate to traditional arbitrage opportunities, but that's the exception rather than the rule.

>Is a Bachelors in Economics a meme degree?

That depends where you get your degree.

Economics degrees can be delivered at a really academic standard which involves some decent level of mathematics. However, its also quite easy to dumb down an economics degree.

Personally, I would say that if you are going to a top school, then economics could be a good degree. If you go to a mid tier school, then you would be better off studying maths or physics. The maths is the hard part of economics, the actual concepts arent that difficult. A maths/physics degree will equip you far better than an economics degree from a mid tier uni.

Source - I have an economics degree from a mid tier university.

I think that modern textbook reflect that. Nobody actually believes prices are static I hope.

Economics is mostly a meme.

At some point economics wanted to become a hard science field, so they went from a sort of "philosophical" approach to a more mathematical approach. The result is graphs and models and junk that has no chance of taking all factors into consideration and therefore not really relevant to the real world.

>no upstart costs

Sure a perfect competition works, as long as you have perfect conditions
>>
>>1540984
Yeah, some of the hypotheses are really retarded.
>>
>>1540969
I dont know what calc 2 is, we dont have that system in the UK.

Tbh the level of maths I studied at undergrad was really disappointing, so I cant say exactly what is needed for decent standard econ. At the time it seemed nice to just have to cover the simple topics, and they hardly advanced it over the three years, but in reality youre losing out on necessary skills for the job market.

However, I did do finance masters at a top uni. For finance, you need to be strong on PDEs and Ito Calculus which cover a lot of the pricing and stochastic models. Probability theory and statistics is also essential. A lot of the concepts in finance are taken from and applied in a similar way to what you would see in a physics degree. A lot of professors in that area have a physics background. Its easier to get a really good understanding of the area and then apply it to finance or economics than it is to study those topics from the beginning.
>>
>>1540982
Not from what I've seen. Granted, I haven't looked through 'every' textbook. It's less that they believe prices are static (even though it's implied by the supposed end result) but that the movement of prices are movements toward equilibrium. However, they don't make mention of why this supposed equilibrium never seems to be reached.

>>1540984
>so they went from a sort of "philosophical" approach to a more mathematical approach.
Exactly. I'd like to see a return to conceptual and logical debates of economics. The only thing modeling does is give economists a false sense of confidence in their theories. The fact of the matter is, even if your theory is trash, I can guarantee you could still contrive a model which supports your theory.

Expanding on what

>>1540948
this guy said.

I go to a mid tier uni and my friend is doing economics and I'm doing engineering + finance. The math I did first year for engineering is similar if not the same as a friend that studied economics first year. We are now second year in and my mid tier economics friend hasnt touched calculus.

It's really just not the same, mid tier unis recognise they don't have top students so they have to dumb it down a bit so they can get more money. I think that goes for most courses.

Courses in general are like that, I've found that for stuff like engineering it gets a fair bit more theoretical the "better" the uni. I get lots of practical questions for math, whereas my top tier uni math friends get a small amount of out there math questions

I tried reading Soros' book The Alchemy of Finance and I thought this is guy is writing on a whole higher level. I'm usually pretty smart and have a high reading level but this was beyond me. What am I missing? What prerequisites do I really need to grok this?
>>
>>1540828
Definitely a meme. It oversimplifies what is always a very complex situation, it rarely reflects real life, despite the best efforts of economemes it does not properly factor in psychology (both individual and aggregate), consumer behavior, government and private intervention and hundreds of other factors.

SD curves will be used in almost every economics class to explain some past event, which is terrific i'm sure, but it cannot predict future events and can't even estimate them, so realistically it exists solely for economists to pretend that their field of psuedo science is valid, when much of the microeconomic side of things has almost no value in real life.

models of this sort should generally be avoided.

take economics 101 and have experience with the stock market

some of it goes over my head, he doesn't use the same vocabulary i'm familiar with from my 101 class
>>
>>1541481
So just reading some Economics 101 textbooks and then I should be able to take on Alchemy of Finance?
>>
>>1541510
i mean, Alchemy of Finance is not THAT abstract
all you need to know is that there are more factors that go into the supply and demand curve than meets the eye; it can be observed in stock expectations. Essentially, there's more chaos to the world, and more misdirect than a simple curve can suggest. Really, things tend to follow the equilibrium IN GENERAL, but things aren't that black and white.

Economists are no better than historians, they are never able to predict anything, but they sure do know how to "explain" (aka they just make it sound complicated AF so you just give up and agree with them) why something happened once it happens.

this might sound like a meme, but I went to a top 10 business school, and its actually true, especially in term of math, economics, statistics and modelling. Most of our courses were based on "managerial skill". Its fantastic for making connections and opening doors, but I had to spend another year studying to get into an industry that I actually wanted to go into (data science/analytics)
>>
>>1540866
econ is good because it can teach you statistical modelling and data analysis, which is actually useful. It also teaches you meme economic theories and things dreamt up by intellectuals that dont have basis in reality, but look good in models

What's the deal with managerial skills? Most of them seen like "how not to be an autist while working".

When I got into bussines school I thought I would get insights on other stuff. I've 2 years to finish so changing careers is not viable, plus finance and accounting courses (which seems more useful) are present during the last periods. I might specialize in finance or economics, that stuff seems more interesting than organizational behaviour and bussines management.

Absolutely. Same goes with masters. Has nothing to do with real life and 99,9% of things you'll learn you will never use or would even know how to implement. just made up bullshit.

and btw "bachelors in economics" means 95% of your classes are something else than economics. some basic math or whatever marketing bullshit

I took a significant number of economics classes too. My last two years were full of econ classes.

Calc 2 covers integral calculus, infinite series, and vectors

In my school the math mostly consisted of Algebra and basic differential calculus. The most "advanced" thing we used were partial derivatives.

Obviously your level of maths required depends what you want to go in to. Its possible to get banking/finance/accounting jobs with that level of maths.

However, given my experience, I think you should study at least partial differential equations so you can deal with Black Scholes. Take a course on it, or self teach if possible.

Can't you argue that this is in large part because of variable supply, demand, and costs? The price of oil influences transport costs. There's always research on reducing costs of production. Companies raise prices because they have data to prove that people will pay it, etc etc etc.

Equilibrium requires almost all external factors to be static, which they aren't.

Just a familiarity with markets and the theories academia pushes in Econ classes. Most of the book is him discrediting and debunking equilibrium theory (the theory that prices gravitate towards some equilibrium).

>>1541521
>there are more factors that go into the supply and demand curve than meets the eye
Well, the central theme to reflexivity is that supply and demand curves (as an example) are near useless because it doesn't model reality. Reflexivity suggests that the market can influence the individual and in turn, the individual inherently influences the market in a feedback-loop fashion; hence the trends we see everywhere.

> things tend to follow the equilibrium IN GENERAL
Equilibrium theory would say that as the price of a product increases, the demands falls. However, in reality, this would only occur in the event of an extreme price increase. We witness companies every quarter pull off what would be impossible under equilibrium theory; companies often raise the price of their product yet simultaneously see a rise in the total units sold.

A tendency toward equilibrium is something only witnessed when it relates to a traditional arbitrage opportunity. Such opportunities only occur when essentially equivalent (or its exact functional opposite) things have meaningfully different prices--something which is just illogical.
>>
>>1544155
>Can't you argue that this is in large part because of variable supply, demand, and costs?
Reflexivity theory suggests that markets are always biased--particularly toward the prevailing assumption. We can say peoples' bias about how they think supply or demand is going to affect the future influences prices at most.

>The price of oil influences transport costs
But this isn't related to supply and demand, it's an extension of the effect of changing market prices

>Companies raise prices because they have data to prove that people will pay it
For starters, you can never "prove" that something which has yet to happen, will happen (you cannot prove that people in the future will pay something, you can only assume it). We could say that the prevailing bias within the company is that if prices are raised, people will continue to pay for the product.

Note: this price increase doesn't need to be justified by a decrease in supply or an increase in demand. Equilibrium theory make an assumption that all market participants have a perfect understanding of the situation that they're in, which is ridiculous.

>Equilibrium requires almost all external factors to be static, which they aren't
I'm not sure what your point is. Are you trying to debunk equilibrium theory?
