“…Third, researchers have integrated non-linearity into IO models by replacing the Leontief production function with other production functions, such as generalized Leontief (Frenger, 1978;Bonnici, 1983;Morrison, 1988;Kratena, 2005), Cobb-Douglas (Zhao et al, 2006), CES (Okushima and Tamura, 2009) or nested functions (Tokutsu, 1994;Zhang, 2008;Cardenete and Sancho, 2012). The use of these production functions, combined with capacity constraints in factor markets, results in price-induced input substitution.…”
