When Does Determinacy Imply Expectational Stability?
We study the connections between determinacy of rational expectations equilibrium, and expectational stability or learnability of that equilibrium, in a relatively general New Keynesian model. Adoption of policies that induce both determinacy and learnability of equilibrium has been considered fundamental to successful policy in the literature. We ask what types of economic assumptions drive di...
متن کاملWhen does Functional Encryption Imply Obfuscation?
Realizing indistinguishablility obfuscation (IO) based on well-understood computational assumptions is an important open problem. Recently, realizing functional encryption (FE) has emerged as promising directing towards that goal. This is because: (1) compact single-key FE (where the functional secret-key is of length double the ciphertext length) is known to imply IO [Anath and Jain, CRYPTO 20...
متن کاملAllocating Household Time: When Does Efficiency Imply Specialization?
When does efficiency in the household imply specialization? For example, if we recognize two sectors, “market” and “household,” when does efficiency imply that one spouse specializes in the market and the other in the household? If efficiency did imply specialization, then egalitarian marriages would be inefficient and an equity-efficiency tradeoff inescapable. This paper clarifies the roles th...
متن کاملWhen does the Haver property imply selective screenability?
We point out that in metric spaces Haver’s property is not equivalent to the property introduced by Addis and Gresham. We prove that they are equal when the space has the Hurewicz property. We prove several results about the preservation of Haver’s property in products. We show that if a separable metric space has the Haver property, and the nth power has the Hurewicz property, then the nth pow...
متن کاملWhen Projective Does Not Imply Flat , and Other Homological
If M is both an abelian category and a symmetric monoidal closed category, then it is natural to ask whether projective objects in M are at, and whether the tensor product of two projective objects is projective. In the most familiar such categories, the answer to these questions is obviously yes. However, the category M G of Mackey functors for a compact Lie group G is a category of this type ...
