Calculate y, f, g, q, h, and r vectors and the W matrix

Description

Note that a necessary condition for calculating the f, g, and r vectors is that the R_bar, U_bar, and V_bar matrices should have only one entry per column and row, respectively, meaning that all products entering a given industry need to be unit homogeneous before we can calculate the f vector and all products of a given industry are measured in the same units before we can calculate the g vector. If the unit homogeneity assumptions above are violated, we will return NA for violating industries in the f and g vectors. The checks for unit homogeneity are performed only when an S_units matrix is present.

Usage

calc_yqfgW(
  .sutdata = NULL,
  method_q_calculation = c("sum_U_Y_rows", "sum_R_V_cols"),
  R = "R",
  U = "U",
  V = "V",
  Y = "Y",
  S_units = "S_units",
  y = "y",
  q = "q",
  f = "f",
  g = "g",
  h = "h",
  r = "r",
  W = "W"
)

Arguments

.sutdata	a data frame of supply-use table matrices with matrices arranged in columns.
method_q_calculation	Specifies the method with which the q vector should be calculated. See details.
R	The resources (R) matrix or name of the column in .sutmats that contains same. Default is "R".
U	The use (U) matrix or name of the column in .sutmats that contains same. Default is "U".
V	The make (V) matrix or name of the column in .sutmats that contains same. Default is "V".
Y	The final demand (Y) matrix or name of the column in '.sutmats“ that contains same. Default is "Y".
S_units	The S_units matrix or name of the column in .sutmats that contains same. Default is "S_units".
y	The name for the y vector on output. Default is "y". y is calculated by rowsums(Y).
q	The name for the q vector on output. Default is "q". q is calculated by rowsums(U) + y.
f	The name for the f vector on output. Default is "f". f is calculated by colsums(U).
g	The name for the g vector on output. Default is "g". g is calculated by rowsums(V).
h	The name for the h vector on output. Default is "h". h is calculated by colsums(transpose(R)).
r	The name for the r vector on output. Default is "r". r is calculated by rowsums(R).
W	The name for the W matrix on output. Default is "W". W is calculated by transpose(V) - U.

Details

method_q_calculation specifies the method with which the q vector should be calculated. Default is "sum_U_Y_rows", corresponding to a demand-sided view of q. Alternatively, an analyst can choose to use the "sum_R_V_cols" method, corresponding to a supply-sided view of q. In the case of a balanced ECC, the method does not matter. Both methods give a column vector as a result.

Value

A list or data frame containing y, q, f, g, h, and r vectors and the W matrix.
