ppnewint4: Circulating capital model 4 using the New Interpretation.

In clptheory: Compute Price of Production and Labor Values

Circulating capital model 4 using the New Interpretation.

Description

This function computes the uniform rate of profit, prices of production and labor values for a circulating capital model using the New Interpretation. The model allows differential wage rates across industries and takes account of unproductive labor for labor value calculations.

Usage

ppnewint4(A, Ap, l, lp, w, wp, v, Q, Qp, lp_simple)

Arguments

A	input-output matrix (n x n).
Ap	input-output matrix for the subset of productive industries (m x m).
l	vector of complex labor input (1 x n).
lp	vector of complex labor input for the subset of productive industries (1 x m).
w	vector of nominal wage rates (1 x n).
wp	vector of nominal wage rates for the subset of productive industries (1 x m).
v	value of labor power (scalar).
Q	gross output vector (n x 1).
Qp	gross output vector for the subset of productive industries (m x 1).
lp_simple	vector of simple labor input for the subset of productive industries (1 x m).

Value

A list with the following elements:

meig	Maximum eigen value of A
urop	Uniform rate of profit (as a fraction)
mrop	Maximum rate of profit (as a fraction)
ppabs	Price of production vector (absolute)
pprel	Price of production vector (relative)
lvalues	Labor values vector
mevn	Monetary expression of value using net output
mevg	Monetary expression of value using gross output
Anonneg	Is A Nonnegative? (1=Y,0=N)
Airred	Is A Irreducible? (1=Y,0=N)
