The author utilizes the Panel Analysis of Nonstationarity in Idiosyncratic and Common Components (PANIC) method for the empirical exercise. The analysis reveals strong evidence of stochastic convergence patterns in the series of log per capita emissions for black carbon, carbon monoxide, ammonia, non-methane volatile organic compounds, and nitrogen oxides,...
