Economics has suffered massively from a desire to look like a hard science. Instead its incredibly complicated and can't be reduced to laws. Path dependence, complexity, disequilibrium are all part of what is taught in (most) graduate schools these days, but this is a very elite group. The majority of the profession are undergraduate degree holders that do not appreciate that they only have illustrative models rather than complete solutions when they try and apply their skills in government.

The neoclassical model is just the benchmark model. It is the simplest one. It helps you understand some things. What people from the natural sciences might not understand is that our models are not perfect descriptions of reality. We know that. They are very imperfect descriptions of a certain realm we are studying. If you are thinking about financial crisis, you add some more structure. If you want to think about monopolies, you add a different hypothesis on your market structure. The problem with economics is that we have a plethora of models, but we don't always know exactly which one to use in each circunstance. We still need to better provide validity to the assumptions we make, test the theories using our newly acquired and decent statistical techniques (RDD, diff-in-diff and IV), replicate more studies and throw away the models that don't work well. We are still a scince in the making, on the transition between a philosophical, assumption-based field, to a scientific, empirical-driven field. We have some very good results in some areas: we know for certain some things about trade, about demand and relative prices, about aggregate demand and recessions, how to do an auction and how to evaluate public policies. But we still don't know for sure a hell lot.

No economist think he can predict the exact path of any economic variable. I'm completely open to any help from outside the profession.

The economy should be looked at as a complex adaptive system. Every attempt to observe the whole system, its behaviour or outcomes will ultimately chance the whole systems or groundings on which I based my attempts to change it in the first place. People are part of the economy and that is also why it is so completely different from Physics (although I don't know much about physics). And that is also, in my opinion, why the contemporary upcoming of the connections between psychology, behavioral sciences, neurosciences and social sciences with economics are very important. Interpretation is key.

But in the same vein an economist can accurately predict how the sales of a product will change with the price. Newton had to invent calculus in order to work with more complex systems than physics understood until then. Economics needs a similar advance. Everything in the economy follows a pattern. The same way the weather systems follow a pattern. The issue is we haven't got the skills to accurately predict the patterns because they get so complex.

What political economists such as Henry George understood but too many modern economists have ignored is that the laws governing the production and distribution of wealth are laws of tendency. Outcomes are subject to powerful externalities, the most powerful of which is how government raises its revenue. George expanded on Smith and Ricardo and Turgot to apply the law of rent to all of nature. Rent is societally-created by aggregate demand. Rent is public revenue. (continued)

What the doctor has described is the "efficient market' Theory which indicates that the market is never wrong and will discover the value through the balance of investor sentiment. He aludes to many equilibria, which is the market in different cycles of the economy. At times the market has ascribed to "the greater fool" theory which indicated perpetual growth. Stocks could be purchased anytime and someone else would eventually pay more. Now the economy seeks the discounted future value.

@Sewblon 6 жыл бұрын

2:09 Not necessarily. What you just described is competitive equilibrium. In Nash Equilibrium, not everyone is happy. But no one wants to change it. Its like that one line from South Park: "Everyone is sick of it. But everyone is waiting for everyone else to stop." The important thing here is that markets don't necessarily maximize happiness. They only equalize quantity supplied and quantity demanded. The economy is a very path-dependent system. But it almost doesn't matter. What path you go down is in and of itself a function of what you learn. You can't predict what you will learn, that would imply that you have all ready learned it. Also, you hinted at this problem. But you didn't bring it into the open. Even knowing that there are vast numbers of equilibria, we don't actually get to choose which one we live in, at least not directly. When politicians craft and implement public policy, they are not choosing between equilibria, they are choosing between different social arragements. So knowing which equilibria are possible only helps if you know which social arrangement corresponds to which equilibria.

To further your point techfighterminal. With the limited ability for new oil companies and refineries to exist because of choking regulation there is very limited competition in the petrol market today.

This is because of the monopoly large oil companies have over the market and can fix prices to keep sales and in turn margins high.

The thing is neoclassical model is a very simple method to teach people how to think like economists and solve optimization problems. Economics is at the end of the day about optimization. Given a set of simultaneous equations in the form y=AxB or even nonlinear equations how do you find a set of or a single solution that finds a solution to all the values of y. Thats real economics, but to be able to add forward looking behavior, behavioral traits, game theory etc, requires one to first understand the basic model. Just like you learn algebra in math before learning calculus, you learn the basic econ models ISLM for example and Profit/Utility maximization to build that basic understanding of how systems of equations relate to each other to then extend into more complex systems of equations. Kind of like in physics you start with newton you dont go into relativity immediately. Modern Economic theory is based around not one equilbrium but a changing equilbrium point that is affected by impulses or shocks. It examines the movement of the curves from one equilbria to another over time(dynamic) or it examines the effects of an external shock on the movement of an equilbrium from one point to another(static). Thats really what economists do is solve a series of simultaneous equations which in turn are built based on a set of axioms/proofs which find support from empirical real world data analysis and probability/statistical theory. Of course when politics comes into the picture the equation changes but real economists try not to get involved in the politics and focus more on understanding the theory or empirics.

@elietheprof5678 4 жыл бұрын

If the simple model was a reasonable approximation of reality, then it would be worthwhile. But what actually happens is: even small deviations lead to huge differences in outcomes. For example in a perfect free market, it would be fine if the top 0.1% owned 70% of the wealth. But as soon as there's even a tiny bit of corporate lobbying, the market stops serving the needs of the people.

Equilibrium is built by arbitrage. Look up Austrian economics. In a single day or weekend a market obviously cannot reach equilibrium, but financial intermediation and arbitrage maintains an intertemporal equilibrium of the long-term. People are confused by neoclassical equilibrium because it eliminates profits from prices, but Austrians understand that originally interest (normal profit / interest) is a necessary component of equilibrium prices. Intertemporal equilibrium, after all, can only be maintained by intertemporal exchanges like loan banking, arbitrage and capital investments.

While the equilibrium theory is good at convincing politicians that we don't need regulations, it is not good at convincing politicians that business cycles are normal and desirable. We want to stay away from equilibrium as much as possible, and produce large swings in the business cycles as much as possible. Otherwise, we get the much dreaded "stagflation." I suggest we pursue the following program: 1) Reduce taxes and regulations in order to produce inflation and high asset prices. 2) The rich should then sell their inflated assets to unwary buyers and complain that we must do something about inflation. 3) The Federal Reserve should then raise interest rates to crash the economy. 4) The rich should then complain that we should cut taxes even more, lower interest rates, and increase government spending, to get out of the depression by re-inflating the economy. 5) The rich should then buy up the depressed assets using money borrowed at low interest rates. (Only the rich are qualified to borrow at this time in the cycle.) 6) Repeat the above, endlessly.

The failure of societies to treat rent as public revenue has resulted in societies dominated by landed interests, hoarding of natural resources (including prime building sites in cities and towns) and intense speculation. This diverts scarce financial resources from productive investment in capital goods in favor of a financial transactions economy. Deregulation exacerbated but did not create the fundamental problem.

Modern free market economics is an ideology with equations. It begins with the ASSUMPTION that efficiency/profit is the #1 priority and goal, then it constructs mathematical models that show how to achieve that efficiency/profit, then it claims "ergo: deregulation, etc. -- we have arrived at the scientific economic system!". The whole thing is a circular logic loop. You have to agree with its value-based assumptions before you even begin. This serves elite interests, of course.

I agree with Lee, however streamlining is at the heart of this problem. The goal of capitalism is for people to be able to act and trade freely. And the true goal of businesses is not profit, but it's creating value [and avoiding capital destruction]. The way to create value and stay capitalist is to let people create this value so that they can obtain freedom to act. Another issue is that value is completely subjective, if people are of the opinion that something is worth less it is actualized.

The fascination with these self adjusting Economic forces drove me to study economics and even get two masters in it. But the more I studied the subject it has become apparent that economists must understand that to get a model that is completely accurate about how the real world works you will have to account for all the variables in the universe ! This is simply impossible no matter how much computational power you have. To get over this problem, economists use a neat trick called econometrics which is basically using statistics to approximate economic models. Economists have gone to great lengths to make their work sound fancy by adding complicated math from STEM fields but this is just like putting up some make up to hide the ugly truth beneath.

Well, those treating scientific disciplines like opposed religious confessions do not base their position on rationality in the first place, so I do not believe I can convince them. And I usually ignore the needless drama, unjustified smugness and ignorant hate that characterizes conflicts between religious fanatics. I just replied to the remark because it was a top comment, and I wanted to show that not *everyone* agrees with it.

I remove it within the sentence. So, it changes from 'He took my wife and me out to dinner' to 'he took me out to dinner'. Still proper. But, if you take out 'my wife and' from 'He took my wife and I out to dinner', It becomes 'He took I out to dinner'. Not proper. Hopefully I've been more clear here :)

The real issue is that every economic model is inevitably flawed. There are just too many ever changing variables

Justin King so what? For finance we can model, for lets say future value of an investmnet, adjusted for inflation for 5 years. Will the model be correct? Almost definetly not, we do not know the inflation for the next 5 years, or what happnes to our investment in those 5 years. But that does not mean that the model has no purpose, and its the samer thing with economics.

Justin King the same could be said about physics and lets remember a lot of stuff we take as truth in physics is just theory.

Kevin fuller That you wrote "just" theory really shows me that you don't understand the usage of the word theory in science. You have nothing to add here if you don't even know the basics of what you're criticising. Furthermore scientists don't take theories as truth. We see theories as more or less accurate descriptions of our world that could at any time be improved by new theories. That doesn't make the previous theories less accurate or less usefull though. Example: We know now that Newtonian physics can not describe the whole world yet we still use it. It's still immensly usefull and still yields highly accuarte results if you know when to use it.

I study fractals and am an economist. I have modelled the fractal and found the economy grows and develops (and much more) as a fractal. My model also corresponds with cosmology observations and conjectures. I am about to publish on quantum foundation problems; I have found they are all problems of the fractal. Understand the fractal, understand the universe.

You couldn't be more wrong. Physics, from its very beginning, has been able to accurately predict future events such as: this amount of force will move this amount of weight. Since Newton all the laws of motion are fully understood but that doesn't mean that before his synthesis physics was unable to predict future events accurately.
