Capital stock model 2 using the New Interpretation.

Description

This function computes the uniform rate of profit, prices of production and labor values for a capital stock model using the New Interpretation. The model allows differential wage rates across industries but does not take account of unproductive labor for labor value calculations.

Usage

ppnewint6(A, l, w, v, Q, D, K, t, l_simple)

Arguments

A

input-output matrix (n x n).

l

vector of complex labor input (1 x n).

w

vector of nominal wage rates (1 x n).

v

value of labor power (scalar)

Q

gross output vector (n x 1).

D

depreciation matrix (n x n).

K

capital stock coefficient matrix (n x n).

t

turnover times matrix (n x n diagonal).

l_simple

vector of simple labor input (1 x n).

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

Nnonneg

Is N Nonnegative? (1=Y,0=N)

Nirred

Is N Irreducible? (1=Y,0=N)
