micEcon
Tools for microeconomic analysis and microeconomic modelling in R
News
- December 2008:
The functions for writing input files for and reading output files
of
FRONTIER 4.1
("front41WriteInput" and "front41ReadOutput")
have been moved to the
frontier package.
- September 22, 2008:
The micEcon package is developed on R-Forge now.
Its summary page is available here.
What is micEcon?
-
micEcon is an extension package for the "language and environment for statistical computing and graphics" called R.
-
micEcon provides functions for microeconomic analysis and microeconomic modelling.
What can micEcon do?
-
Demand Analysis with the "Almost Ideal Demand System" (AIDS): The AIDS is the most popular demand system in empirical demand analysis. micEcon provides functions for:
-
econometric estimation using the popular but inaccurate "Linear Approximation" (LA-AIDS) and the accurate "Iterated Linear Least Squares Estimator" (ILLE)
-
searching for the intercept of the translog price index (alpha_0) that gives the best fit to the model
-
optional imposition homogeneity and symmetry
-
checking for monotonicity and concavity
-
predicted quantities and expenditure shares
-
Marshallian (uncompensated) price elasticities, Hicksian (compensated) price elasticities, income elasticities, and their standard errors
-
Production Analysis with the "Symmetric Normalized Quadratic" (SNQ) profit function: The SNQ profit function is often used in microeconomic production models because it allows the imposition of global convexity. micEcon provides functions for:
-
econometric estimation
-
imposition of global convexity using a recent two-step estimation procedure
-
price elasticities of inputs and outputs and their standard errors
-
fixed factor elasticities
-
shadow prices of fixed factors
-
Hessian matrix and its derivatives with respect to coefficients
-
predicted profits and netput quantities including the standard errors and the confidence limits of prediction
-
Analysis with Translog Functions:
-
econometric estimation
-
calculation of derivatives with respect to regressors
-
calculation of (bordered) Hessian matrices with respect to regressors
-
checking monotonicity (positive or negative)
-
checking curvature (quasiconcavity, concavity,
quasiconvexity, convexity)
-
creating a matrix that can be used to impose monotonicity
using a two-step procedure
-
Analysis with Quadratic Functions:
-
econometric estimation
-
calculation of derivatives with respect to regressors
-
Tools for Matrices:
-
inserting additional rows and columns into matrices
-
creating symmetric and triangular matrices
-
conversion between a symmetric matrix and a vector of its linear independent values
-
tests for positive and negative semidefiniteness
