Fallacy of the Multiplier Effect: Correcting the Income Analysis
2006
Social Science Research Network
This note shows that useless public works is equivalent to unemployment relief expenditure in the presence of unemployment and that the argument on the multiplier effect seriously misleads the present ...
However, it has a serious fallacy even if we accept the consumption function. ...
From (2) , (3) and (4) one has y d = c(y d ) + i, showing that neither z nor g has any effect on disposable income y d : d y d /dg = 0, dy d /dz = 0. (6) Since (2) , (3) and (5) imply y v − θg ...

Analysis of a Classical Matrix Preconditioning Algorithm

pre-print
A balancing operation scales the ith row and column so that their maximum entries are equal, and requires O(m/n) arithmetic operations on average, where m is the number of non-zero elements in A. ...
This is the first time bound of any kind on any variant of the Osborne-Parlett-Reinsch algorithm. ...
We have analyzed one variant of the Osborne-Parlett-Reinsch algorithm, namely the L ∞ version with some additional conditions on the order of balancing operations. ...

Space-Bounded Kolmogorov Extractors
[chapter]
2012
Lecture Notes in Computer Science
An extractor is a function that receives some randomness and either "improves" it or produces "new" randomness. There are statistical and algorithmical specifications of this notion. ...
Following Zimand we prove the existence of such objects with certain parameters. ...
To get the strong Kolmogorov extractor property we need to replace a balanced table by a rainbow balanced one with parameters (2 k ,Q = 2 m−d ) where again d = δ + c log n. ...

Lecture Notes in Computer Science
We prove the decidablity of one of our extensions and the undecidability of a slightly richer one. We introduce first-order encodings to automate reasoning over software transitions with summations. ...
AbstractSome of the most significant high-level properties of currencies are the sums of certain account balances. Properties of such sums can ensure the integrity of currencies and transactions. ...

Difference Balanced Functions and Their Generalized Difference Sets
[article]
2013
arXiv
pre-print
In the literature, all existing such functions are associated with the d-homogeneous property, and it was conjectured by Gong and Song that difference balanced functions must be d-homogeneous. ...
First we characterize difference balanced functions by generalized difference sets with respect to two exceptional subgroups. ...
Suppose that a function f : F * p n → F p is difference balanced. Then f must be d-homogeneous, i.e., f (ax) = a d f (x) for each a ∈ F * p with gcd(d, p − 1) = 1. Proof. ...

Tiling pictures of the plane with dominoes
1997
Discrete Mathematics
We consider the problem of tiling with dominoes pictures of the plane. in theoretical and algorithmic aspects. For generalities and other tiling problems, see for example Refs. ...
Such a function is called a height function on the picture. Note that for every vertex t of C we have h(t) < g(t). ...
every vertex s E Ci with a given value U, we have h(s) d c: and we have equality for some vertex of Ci (to do that, calculate any height function on Ci, and adjust it by means of a constant). ...

A graph G is symmetric with respect to a functional Fc(P) defined on the set of all the probability distributions on its vertex set if the distribution P* maximizing Fa(P) is uniform on V(G). ...
We show that the class of graphs which are symmetric for the functional appearing in the capacity formula of Cohen et al. (1968) and Gargano et al. (1993) coincides with the graphs admitting a 2-matching ...
