comment What are Reinert's reproaches to the Ricardo theory?
It will take me some time for finding the last two papers in the library, but this already sounds as if you were trying to answer another question, not the one I was asking. You say "with no logical problems", but my current question is: "In which sense these corrections solve the problems? One can imagine that introducing new parameters, supply and demand, solves the logical paradoxes (i.e. removes the uncertainity in the decisions), and changes the quantitative picture, but does not solve the problems qualitatively." Could you comment this?

comment Unbounded operator
If $C^2$ means the space of two times continuously differentiable functions, then this operator is bounded, since it acts from $C^2[a,b]$ to $C[a,b]$, and the last space is continuously embedded into $L^2[a,b]$. Or what do you mean?

Will, who introduced these parameters in the theory, supply and demand? Ricardo himself?

@PeterLeFanuLumsdaine, if there is no problem here, and everything is written in textbooks, you can answer the last questions in my Edit.

Who is the author? Ethier?

Does this mean that the theory that I am looking for (without those paradoxes) exists?

comment Uniform definition of $S(\mathbb{R})$ and $S(\mathbb{Q}_p)$
For any LCA-group $G$ the multiplication by a real character on $\widehat{G}$ corresponds to the differentiation over a one-parametric subgroup in $G$, that's why I am speaking about polynomials. I don't know whether the multiplication by $|x|^k$ gives the same class of functions, I don't have intuition in $p$-adic fields.

comment Uniform definition of $S(\mathbb{R})$ and $S(\mathbb{Q}_p)$
Yes, this seems to be true, if we change a bit the definition of a polynomial: $p$ must be locally representable as a finite linear combination of finite products of real characters.

comment Uniform definition of $S(\mathbb{R})$ and $S(\mathbb{Q}_p)$
Your question is very vague... I can formulate a hypothesis: perhaps ${\mathcal S}(G)$ is the subspace in $L_2(G)$ consisting of functions $f:G\to{\mathbb C}$ such that $f$ and its Fourier transform $\hat{f}$ rest in $L_2$ after being multiplied by any polynomial $p$ (where a polynomial on $G$ is a linear combination of finite poducts of real characters, i.e. continuous homomorphisms $r:G\to{\mathbb R}$). I don't know, whether this is more intuitively reasonable (and whether this is true).
