Isosingular Sets and Deflation
This article introduces the concept of isosingular sets, which are irreducible algebraic subsets of the set of solutions to a system of polynomial equations that share a common singularity structure. The definition of these sets depends on deflation, a procedure that uses differentiation to regularize solutions. A weak form of deflation has proven useful in regularizing algebraic sets, making t...
متن کاملDeflation and Consumer Expenditures
One often hears that one reason deflation should be avoided is because it leads to the expectation of lower prices in the future on the part of consumers. This in turn causes consumers to defer their spending. The consequence of this is reduced demand for products and lower investment by firms now. The net result is weaker economic activity. This paper provides a new approach to verify this view.
متن کاملDeflation : Current and Historical Perspectives
NBER, as indicated where relevant. 2For a quick introduction to the history of deflation at the end of the nineteenth and at the beginning of the twentieth century, including a substantial amount of data, cf. Bordo et al. (2004). 3This paper by Bordo and Redish was published in March 2003 as NBER Working Paper 9520. It has already received a comprehensive discussion and very important comments ...
متن کاملOn deflation and multiplicity structure
This paper presents two new constructions related to singular solutions of polynomial systems. The first is a new deflation method for an isolated singular root. This construction uses a single linear differential form defined from the Jacobian matrix of the input, and defines the deflated system by applying this differential form to the original system. The advantages of this new deflation is ...
متن کاملDebt Deflation and Bank Recapitalization
During some recent financial crises, the majority of domestic banks or indeed the entire banking sector became insolvent. We have analyzed the welfare effects of policy responses to bank insolvency by examining a modified version of the Diamond-Rajan model, introducing a fiat currency. The sources of inefficiency in our model are the ”moral hazard in banking” and the “premature liquidation of b...
