The Effects of Non-Tariff Measures on Prices, Trade, and Welfare: CGE Implementation of Policy-Based Price Comparisons (2004, methodology): “Kennedy (1981) notes that the Halvorson/Palmquist transformation is biased upward, and develops a correction.12 More recently van Garderen and Shah (2002) argue that the Kennedy correction should be used with an approximate unbiased variance estimator to construct tstatistics.13 Thus, the NTM price…”
Does energy efficiency matter to home-buyers? An investigation of EPC ratings and transaction prices in England (2015, methodology): “1 The ‘raw’ coefficients of the EPC dummy variables require adjustment to determine the percentage premiums (or discounts) as suggested by Halvorsen and Palmquist (1980) and Giles (2011): our simplified adjustment formula follows the van Garderen and Shah (2002) method where the proportional impact ”

The Limits of Model-based Regulation (2014, unknown): “The last two lines of Panel A include adjusted coefficients and estimates for the standard errors, following the reasoning of Halvorsen and Palmquist (1980), Kennedy (1981), and van Garderen and Shah (2002) (see footnote 36).”

Going NUTS: The Effect of EU Structural Funds on Regional Performance (2010, unknown): “Hence, Objective 1 treatment caused absolute GDP to change by about 14Note that the semi-logarithmic equations we estimate would actually require a slight transformation of the estimated coefficients following Van Garderen and Shah (2002).”
Energy Performance Ratings and House Prices in Wales: An Empirical Study (2015, unknown): “Adjusting the coefficients of the semilogarithmic estimation for potential bias as proposed by Kennedy (1981) and van Garderen & Shah (2002) yields minimally different effects in the order of magnitude of 0.01%.”
