This dataset supports the empirical analysis of the first adoption of national carbon pricing (carbon taxes and emissions trading systems) in 51 countries over 1996 to 2024 (29 annual periods). The model is a spatial transition probit in which post adoption years are removed from the set of countries at risk. Participation in supranational systems such as the European Union Emissions Trading System is not counted as adoption unless the country also introduced a national instrument. All files are MATLAB (.mat) files, and the country order is identical across files. Files IT_carbon.mat: the estimation data. N = 51 countries; T = 29 years; years = 1996 to 2024. data: a cell array with one 51 by 35 matrix (X) per year, holding the explanatory variables and the adoption indicator for each country. The first column is a constant. No values are missing. adoptiondate: a 51 by 1 vector with each country’s adoption period counted from 1996 (0 = adopted before the sample period; Inf = no national carbon pricing instrument by the end of 2024). W (also stored as A, B and C): a 51 by 51 row standardised weight matrix used in estimation. countries and xvars: country names and variable names. W_trade_export_1996.mat: the baseline trade weight matrix. W_raw_trade_export_1996 contains the raw bilateral export flows for 1996, and W_trade_export_1996 contains the same flows after row standardisation (each row sums to one, zero diagonal, not symmetric). Rows show a country’s export shares across destination countries. W_trade_import_1996.mat: the same construction using bilateral import flows for 1996 (robustness check). W_trade_total_1996.mat: the same construction using total bilateral trade (exports plus imports) for 1996 (robustness check). W_trade_export_2000.mat: the same construction as the baseline using bilateral export flows for 2000 (robustness check on the base year). W and W_export_2000 are identical. Notes Bilateral trade flows are taken from the BACI database (CEPII), which is based on UN Comtrade data. Two countries have no recorded trade flows in 1996, so their rows in the 1996 matrices contain only zeros. The row standardised matrices are the ones used in the models reported in the paper; the raw matrix is provided for replication of the standardisation.
