This paper estimates interfuel substitution elasticities in selected developing and industrialized economies at the national and sector levels. In doing so, it employs state-of-the-art techniques in microeconometrics, particularly the locally flexible normalized quadratic functional forms, and...

We investigate biofuel substitution in the U.S. transportation sector, for the period from 1990 to 2017, using the normalized quadratic model. We relax the homoskedasticity assumption and instead assume that the covariance matrix of the errors of the flexible demand system is time-varying. We...

We investigate the demand for energy and the degree of substitutability among fossil fuels in the United States using the Normalized Quadratic (NQ) expenditure function and (to our knowledge) the longest span prices and quantities that have ever been studied before, from 1919 to 2012. In doing...

We investigate interfuel substitution in the United States using the minflex Laurent demand system and a century of data (from 1919 to 2012). We relax the assumption of constant parameters in the demand system, and also relax the homoskedasticity assumption, instead assuming that the covariance...
