Supplementary Estimates
In Table S1 we present estimates of the unknown parameters for each of the 35
sectors in Table 1. These parameters are the coefficients of the explanatory variables in
the state equations (4’) and (5’) and coefficients of lagged values of the latent variables
in the transition equation (12). We have used the parameters of the transition equation
to extrapolate the endogenous rates and biases of technical change given in the
Appendix.
We have constructed constrained two-step maximum likelihood estimates of the
parameters of the observation equation (14). These estimates are presented in Table S1
and correspond to the parameters in the matrix 'A in the definition of the Kalman filter.
The parameters ikβ are the share elasticities and represent the responses of the shares of
the four inputs – capital, labor, energy, and materials – to changes in the input prices in
Equation (5) for a given state of technology. Note that the matrix 'H in the definition of
the Kalman filter involves no unknown parameters and consists of known constants and
functions of the data.

The r’s and q’s are unknown parameters; the matrices R and Q are symmetric and positive semi-definite, as required for a covariance matrix.
In Table S2 we also present estimates of the mean and covariance matrix of the
initial state of technology 1ξ , with 0pf normalized to constant 0. These are defined as
