preferences - Strong monotonicity and weak monotonicity
When you say "if you say that strong monotonic preferences imply weak then all results for weak monotonic preferences should apply to strong ". That's not true, because weak monotonicity requires a stronger condition than strong monotonicity, that is for all elements of a bundle to be greater than the elements of another bundle.
Understanding the Difference: Strong Monotonicity vs. Strict ...
2024年10月9日 · The key difference between strong monotonicity and regular monotonicity is that, in strong monotonicity, the preference for bundle a over bundle b requires that a and b are distinct. Additionally, the preference for a + c over b + c holds for any positive quantity c, not just any arbitrary bundle c.
microeconomics - Strong Monotonicity vs Strict Monotonicity
Strongly Monotone: A function where f (x) is strictly preferred to f (y) whenever x >> y, or every good in bundle x is purchased at a higher quantity than the corresponding good in bundle y. I understand, on paper, what the difference between these two definitions is.

第五、强单调性Strong Monotonicity. 由上述五个公理，尤其是第四与第五个公理，可以得出妥协解的一般形式。任意的效用值u和v，以及任意的比例k(0<k<1)，都存在某个排序使得它的效用值正好等于ku+(1-k)v。
Monotonicity means that if c 1 contains more of some or all commodities, but no less of any, than c 2 (c 1 c 2) then c 1 % c 2. Strict monotonicity means that if c 1 contains more of each commodity than c 2 (c 1 > c 2) then c 1 ˜c 2 Now let us consider the consequences that arise from monotonicity of preference. De nition 1.8. A function U is ...
Monotonicity: The relation satisfies monotonicity if for all x,y ∈ X, if x k ≥ y k for all k, then x y, and if x k > y k for all k, then x y. In some cases, we will further assume that the consumer is strictly happier with any additional quantity of any commodity. Strong Monotonicity: The relation satisfies strong monotonicity if for all ...
By strong monotonicity: B(x) is non-empty; W(x) is non-empty since 0 ∈W(x); Francesco Squintani EC9D3 Advanced Microeconomics, Part I August, 202420/41
Social Choice Function: Strong Monotonicity A social choice function C isstrongly monotonic, if for any preference pro le [˜] withC[˜] = a, then for any other preference pro le [˜0] with the property that 8i 2N;8a02A;a ˜0 ia 0if a ˜a0; it must be that C[˜0] = a. Strong monotonicity means that if I The current winner is a
Strictly Convex and Strictly Monotonic Preferences
The difference is that strong monotonicity requires only one more of any good to be strictly preferred. Strict convexity (of preferences) means that when $x \neq y$ and $x \succeq y$, then $t x + (1-t) y \succ y$ for all $t \in (0,1)$. Example with no (positive) monotonicity. Consider preferences like those depicted below.
Check Monotonicity and Strong Monotonicity: Explained
2023年12月10日 · While monotonicity provides a general understanding of the relationship between two variables, strong monotonicity takes it a step further. When a relationship is strongly monotonic, it means that as one variable increases, the other variable strictly increases.
