RT Report T1 Environmental fiscal polices might be ineffective to control pollution A1 Fernández Casillas, Mª Esther A1 Pérez Sánchez, Rafaela María A1 Ruiz Andújar, Jesús AB In a one sector growth model with pollution in the utility function, the competitive equilibrium can be indeterminate for plausible values of the intertemporal substitutionelasticity of consumption and under constant returns to scale. The tax rate on pollution does not enter the condition characterizing indeterminacy. This means that thegovernment is not able to control emissions in the economy by using environmental policies. Non-separability between private consumption and pollution in the utility function is crucial for this result. PB Facultad de Ciencias Económicas y Empresariales.
