No.I define economics as being the empirical study of data related to consumption and production as goods and services. Making an economic model is just one of many ways to interpret and understand that data.
But earlier you said, "I meant that there are economic facts (e.g. GDP, employment rate, taxation level, etc.) that simply exist. That is what economics is about." But now you reject that economics is devoid of theory, laws, and models, so economics is about more than just economic facts and that 'they simply exist'; otherwise, you're contradicting yourself. And earlier you said, "in economics there is only reality." But clearly, this is not true. The way the economist views reality is through a certain lens which is shaped by the theory, laws, and models which he brings to the workshop. Without them, he's just staring at data and not understanding how it relates to anything--or at the very least, he would have a layman's understanding of it. At that point, he's not an economist--but he could be an accountant, a (non-econometric) statistician, a mathematician, a math student, or whatever.
Making an economic model is just one of many ways to interpret and understand that data.If you use statistics to study economic data, then you hopefully use economic models (if you do, you probably aren't aware of it). You should read the following:

Metsfanmax wrote:It doesn't. They need models in order to construct reality. You can't 'do economics' without having some economic analytical tools to work with. Otherwise, you'll just stare at the word "GDP" and not know what it resembles nor how it relates to anything.
Economic analytical tools are not dependent on having models of reality. If you think that, you have never heard of statistics.
Again, you miss the point because you forget what you previously said:
"your quote implies that economists cannot get work done if they are not contributing to one of those constructions."
"You directly said that economics is entirely composed of constructions to understand reality. That precludes any of the work that real economists actually do simply to even understand what's going on"
Nor were you answering the previous questions, so I give up with you on this one. You keep forgetting what the topic is (as has been shown previously), so I may as well talk to wall about this one.
There is a difference between statistics and econometrics, but you seem to blend the two. That's okay, but we can't advance this conversation if you don't understand this distinction.
How did you say it? 'I'm not your professor, etc.'?
Here's a reading list:
Peter Kennedy. A Guide to Econometrics, 6th ed.
Stephen Schmidt. Econometrics. 2005This one is awesome:

(because your ambiguity seems to lend yourself to contradiction)
I meant operationally whatever it is that economists actually do.
Not being an economist myself, I don't know all the steps involved in doing economic analysis, so I'm just being quite general and saying that economists can make progress on understanding the nature of the economy without coming up with a model to explain how X, Y and Z factors are "driving" that economy.
Thanks. Now this all makes sense.

How does "math" alone lead one to pick which variables will be used to explain a relationship?
How does "Math" alone allow one to know what trends to make without models--or even without translating an economic model into an econometric model?
How does math determine how the economist can make predictions without subscribing to any particular economic model?
I'm not your math professor. If you don't understand how to use math and statistics to interpret economic data, go take a class, don't ask me.
It's okay to admit that you can't answer these questions. The truth is that math cannot itself address these questions, so you're wrong on this too. One needs economic theory, laws, and models to fit alongside the observations. Otherwise, you would not know which predictions to make, you wouldn't be able to start with a model that frames the question about the relationship among variables, etc.
It is obvious that math alone cannot answer these questions. I'm beginning to think that if you actually do statistics related to economics, then you're simply unaware of the models, laws, and theories of economics as you work.
Metsfanmax wrote:Did you know that economics came before econometrics? What do you think econometricians used in order to analyze data? (Economic models, which are translated into econometric models).
Yes, econometricians can inform economists who use economic models, but it isn't one-way.
Econometrics: I don't think that word means what you think it means.
It is okay to admit that what you said, "You have it backwards. Economic models are not 'translated' into econometric models; econometric models are used to inform economic models," was wrong. It can't be one-way since economics precedes econometrics. How do you think econometrics started? With only math? If so, then it's only statistics. In fact, this economic model and econometric model process is endogenous, but if you admit that it is, then you'll be contradicting yourself.
Anyway, instead of carrying on about the other issues, I can't reason with you if you presume to know that which you do not. Other people don't do this because they're open to acknowledging the boundaries of their knowledge. Instead they ask questions and seek to understand. With you, this is not the case.
Good luck out there.
