Webb6 feb. 2015 · With country fixed effects, the estimated convergence rate is misleadingly high. With data starting in 1870, country fixed effects are reasonable and the estimated convergence rate is 2.6%. Combining the two estimates suggests conditional convergence close to the ‘iron-law’ rate of 2%. WebbProof of Lemma 2.3. Throughout this proof let ϑ1,...,ϑd ∈ R satisfy that ϑ = (ϑ1,...,ϑd). Note that the fact that for all θ = (θ1,...,θd) ∈ Rd it holds that f(θ) = Xd
