The "micEcon" project
Tools for microeconomic analysis and microeconomic modelling in R
News
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.
Which R packages are developed
within the micEcon project?

micEcon: Microeconomic Analysis and Modelling.
This is the base package.
It provides tools for microeconomic analysis and microeconomic modelling, e.g.

analysis with Translog functions,
e.g. 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), and
creating a matrix that can be used to impose monotonicity
using a twostep procedure.

analysis with quadratic functions,
e.g. econometric estimation and
calculation of derivatives with respect to regressors.

micEconAids: Demand Analysis with the "Almost Ideal Demand System" (AIDS).
The AIDS is the most popular demand system in empirical demand analysis.
This package provides functions for:

econometric estimation using the popular but inaccurate "Linear Approximation" (LAAIDS) 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

micEconCES: Analysis with the "Constant Elasticity of Scale"
(CES) function.
Tools for economic analysis and economic modelling with a Constant Elasticity of Scale (CES) function.

micEconNP: Microeconomic Analysis with NonParametric Methods.
Tools for microeconomic analysis and microeconomic modelling with nonparametric methods.

micEconSNQP: "Symmetric Normalized Quadratic"
(SNQ) profit function.
Tools for production analysis with the Symmetric Normalized Quadratic (SNQ)
profit function.
The SNQ profit function is often used in microeconomic production models
because it allows for the imposition of global convexity.
This package provides functions for:

econometric estimation

imposition of global convexity using a recent twostep 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

miscTools: Miscellanneous Tools and Utilities.
This package provides miscellanneous small tools and utilities, e.g. for

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
Who has written the packages in the micEcon project?
