It 15 difficult to obtain c1osed-fonn solutions for input demand equations that are conducive to econometric estimation and policy analysis when the production function IS unknown Developments In the theory of duality facilitate obtaining such equations This article provides three examples of...

The authors examine the small sample properties and forecasting performance of estimators In models using the Box-Cox transformation via a Monte Carlo experiment They develop a simple,estimator for the expected value of the untransformed dependent variable They show that the sign and magnitude...

A particular numerical analytical technique for solving systems of simultaneous equations which offers several advantages to the user over other numerical techniques is discussed. The Gauss-Seidel algorithm is simply an iterative technique which requires no derivatives, matrix inversion,...

Detailed data files required to fill many economic models are not available Direct construction of a needed file often proves to be prohibitively expensive The author of this article poses one alternative to synthesize a file by merging two or more existing ones that. between them, contain the...

In regional income comparisons, relative and absolute measures sometimes produce apparently contradictory results. These can be reconciled if a proper time perspective is utilized. An income gap between regions, relative or absolute, indicates the situation at a particular time, while growth...

The Rotterdam model, a complete consumer demand system, was fitted to personal consumption expenditure data for 1949-77 to study the interaction of consumer expenditures A full matrix of direct and cross price elasticities and income elasticities was estimated The 12 categories of expenditures...
