We investigate in this paper the degree of short-run and long-run comovement in U.S. sectoral output data by estimating sectoral trends and cycles. A theoretical model based on Long and Plosser (1983) is used to derive a ...

We construct S2-sets contained in the integer interval Iq-1:= (1,q-1) with q = pn, p a prime number and n E Z+, by using the p-adic expansion of integers. Such sets come from considering p-cycles of length n. We give ...

Although there has been substantial research using long-run co-movement (cointegration) restrictions in the empirical macroeconomics literature, little or no work has been done investigating the existence of short-run ...

We develop a theory of extensions for involutive and nondegenerate solutions of the set-theoretic Yang-Baxter equation and use it to produce new families of solutions. As an application we construct an infinite family of ...

This paper deals with left non-degenerate set-theoretic solutions to the Yang–Baxter equation (= LND solutions), a vast class of algebraic structures encompassing groups, racks, and cycle sets. To each such solution there ...

The dating of business cycle turning points is still an important basis for economic policy decisions. The present study sets out to trace the Austrian business cycle for the Austrian economy for the period between 1976 ...

Let M = (V, E, A) be a mixed graph with vertex set V, edge set E and arc set A. A cycle cover of M is a family C = {C(1), ... , C(k)} of cycles of M such that each edge/arc of M belongs to at least one cycle in C. The ...

We test for political budget cycles in a panel of eighteen Latin American democracies from 1973 to 2008. Recent studies have argued that the pattern of deficit cycles in a large cross-section of countries is driven by the ...

Cycling is a healthy mode of transportation that also reduces car use and its associated environmental impact. The present study seeks to examine attitudes toward bicycles (versus cars) from a dual-process perspective. ...

Braces and linear cycle sets are algebraic structures playing a major role in the classification of involutive set-theoretic solutions to the Yang-Baxter equation. This paper introduces two versions of their (co)homology ...
