ppnewint3 {clptheory}

Circulating capital model 3 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 has uniform wage rates across industries and takes account of unproductive labor for labor value calculations.

Usage

ppnewint3(A, Ap, l, lp, w, 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

uniform nominal wage rate (scalar).

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)
