“…23 Posteriormente, se utilizaron modelos dinámicos de ajuste parcial por mínimos cuadrados ordinarios dinámicos (MCOD) para verificar los resultados del modelo estático. 24 El primer modelo de MCOD incluyó valores rezagados de la variable de consumo, mientras que el segundo incluyó, además, valores adelantados de consumo. La especificación fue la siguiente: C t =θ 0 +θ 1 P t +θ 2 Y t +θ 3 C t-1 +θ 4 C t+1 +∂Z t +u t (2) donde C t , P t y Y t son los logaritmos de consumo, precio e ingreso en el tiempo t, respectivamente; C t-1 y C t+1 son el rezago y el adelanto del consumo respecto a un periodo de tiempo t, u t es el término de error, θ 0 es el intercepto, θ 1 es la elasticidad precio de la demanda en el corto plazo y θ 3 es el coeficiente del rezago del consumo.…”

Objetivo. Estimar la elasticidad precio y la elasticidad ingreso de la demanda de cerveza en México. Material y métodos. Se utilizaron series mensuales de ventas y precios de cerveza de 2007 a 2019. Se estimó la elasticidad a largo plazo mediante un modelo de mínimos cuadrados ordinarios (MCO). La elasticidad en el corto plazo se estimó mediante un modelo de mínimos cuadrados ordinarios dinámicos (MCOD). Resultados. La elasticidad precio en el largo plazo fue de -1.40 (IC95%: -2.53 a -0.27) y -1.31 (IC95%: -2.46 a -0.15) en el corto plazo. La elasticidad ingreso de la demanda en el largo y en el corto plazo se estimó en 0.86 (IC95%: 0.44-1.29) y 0.93 (IC95%: 0.51-1.34), respectivamente. Conclusión. Los hallazgos de este estudio sugieren que las políticas fiscales pueden tener un impacto positivo en la salud de la población al reducir el consumo de cerveza.

“…Consumption of petroleum C 2020). This higher consumption of petroleum products generated higher air pollution in recent years, which has become a major environmental and economic obstacle (Taghvaee and Hajiani 2014). Gasoline consumption in Iran in 2013 was about 68.4 million L per day, while according to unofficial sources, the volume has reached 91.4 million L per day in 2020, and based on the model presented in this article in 2030 it will reach 101.22 million L per day.…”

This study addressed the urgent need for biofuels even in countries such as Iran, which has fairly good fossil fuel resources. The problems, necessities of the present, and future demand for biofuels are discussed. As the transportation sector is one of the largest sources of air pollution, this study has focused on this sector. This issue was examined from a global perspective, and then within the context of domestic bioethanol production using agricultural residues and proposing different scenarios. The first step in implementing this policy is the accurate forecast of the demand for second-generation bioethanol in the coming years. A nonlinear auto regressive neural network was applied to predict gasoline demand based on Mackey-Glass chaotic time series. Gasoline demand is forecasted by 2030, based on projected volumes of gasoline in different bioethanol mixture scenarios. Results revealed that using scenarios E10, E15, E25, the volume of bioethanol needed by 2030 will amount to 10.12, 15.16 and 25.31 million L per day which can be produced using agricultural products wastes.

Purpose The purpose of this paper is to examine the effects of maritime and air transportation on the environment and economy of Iran. The authors specify two dynamic models of the environmental pollution and the economic growth. Then, the authors estimate the environmental and economic elasticities of maritime and air transportation in short run and long run in Iran during 1978–2012. Design/methodology/approach The authors estimate the environmental and economic elasticities of maritime elasticities in short and long run, using simultaneous equations system. Findings The findings indicate that the short- and long-run environmental pollution elasticities of maritime transportation are higher than those of the air ones. In addition, the economic growth elasticities are greater in the air transportation compared to maritime one. As a result, the maritime transportation is more pollutant and less productive in Iran in comparison with the air transportation. Originality/value The policymakers are advised to improve the infrastructure of maritime transportation from both the environmental and economic point of views. Consequently, the air transportation is considered as a cleaner and more beneficial transportation mode in Iran, where geographical position limits the maritime transport as a widespread transportation mode.
