1 Teaching notes on GMM 1
Generalized Method of Moment (GMM) estimation is one of two developments in econometrics in the 80ies that revolutionized empirical work in macroeconomics. (The other being the understanding of unit roots and cointegration.) The path breaking articles on GMM were those of Hansen (1982) and Hansen and Singleton (1982). For introductions to GMM, Davidson and MacKinnon (1993) have comprehensive ch...
متن کامل1 Notes on moving mirrors
The Davies-Fulling (DF) model describes the scattering of a massless field by a non-inertial mirror in two dimensions. In this paper, we generalize this model in two different ways. First, we consider partially reflecting mirrors. We show that the Bogoliubov coefficients relating inertial modes can be expressed in terms of the frequency dependent reflection factor which is specified in the rest...

متن کاملIntroductory Notes on Rational Expectations 1 Overview
The theory of rational expectations (RE) is a collection of assumptions regarding the manner in which economic agents exploit available information to form their expectations. In its stronger forms, RE operates as a coordination device that permits the construction of a “representative agent” having “representative expectations.” Section 2 of these introductory notes on RE provides several alte...
متن کاملNotes on Differential Geometry , 1 Lars Andersson
1.1. Linear Algebra. Let F = R or F = C and let V be a vector space over F. A finite dimensional vector space over R (C) is isomorphic to Rn (Cn) for some n, where Rn = {x = (x1, . . . , xn)} for xi ∈ R and Cn = {z = (z1, . . . , zn)} for zi ∈ Cn. On Rn, the standard Euclidean inner product is given by 〈x, y〉 = ∑ xiyi and the Euclidean norm is given by ||x|| = 〈x, x〉 2 . On Cn the standard Herm...
