Differential duality
Mantovi, A. - Facoltà di Economia, Università degli Studi di Parma - 2013
A framework for duality theory is set forth, based on the model-independent role of homotheties. An expansion vector field is introduced as global generator of pure expansion effects, in terms of which to deepen the differential aspects of preference symmetries, fundamental identities and...

Theoretical consistency property applied to the micro-economic modelling with flexible functional forms
Moravanský, Dalibor - In: Bulletin of the Czech Econometric Society 9 (2002)
The paper brings a survey of flexible functional forms and summarizes the theoretical properties of several economic functional types (indirect utility, cost, expenditure function and the appropriate input demand systems). The notions of flexibility of the functional fonn (relating to the...

Differentiable Technology, the Curvature of the Profit Function, and the Response of Supply to Own-Price Changes
Somerville, R. A. - In: Journal of Economic Education 38 (2007) 2, pp. 222-228
The author establishes a property of supply for a competitive firm: Assuming differentiability of the production frontier, linearly independent price vectors have disjoint image sets under the supply mapping. This property supports the main results. First, the author drew a simple proof of...

Measuring Economic Growth from Outer Space: A Comment
Berliant, Marcus; Weiss, Adam - Volkswirtschaftliche Fakultät, … - 2013
We examine econometric and elementary economic theory issues arising from the model specification in Henderson, Storeygard and Weil (2012), that uses night light data to proxy for missing or unreliable GDP growth data. An alternative approach based on the expenditure function is outlined. It can...

Cost of Living Indexes and Exact Index Numbers
Diewert, Erwin - Vancouver School of Economics - 2009
The paper reviews and extends the theory of exact and superlative index numbers. Exact index numbers are empirical index number formula that are equal to an underlying theoretical index, provided that the consumer has preferences that can be represented by certain functional forms. These exact...

Exact and Superlative Price and Quantity Indicators
Diewert, Erwin; Mizobuchi, Hideyuki - Vancouver School of Economics - 2009
The traditional economic approach to index number theory is based on a ratio concept. The Konüs true cost of living index is a ratio of cost functions evaluated at the same utility level but with the prices of the current period in the cost function that appears in the numerator and the prices...
