Computable general equilibrium models are known as a powerful instrument in economic analyses and widely have been used in order to evaluate trade liberalization effects. The purpose of this study was to provide the impacts of trade openness on pharmaceutical industry using CGE model.
Using a computable general equilibrium model in this study, the effects of decrease in tariffs as a symbol of trade liberalization on key variables of Iranian pharmaceutical products were studied. Simulation was performed via two scenarios in this study. The first scenario was the effect of decrease in tariffs of pharmaceutical products as 10, 30, 50, and 100 on key drug variables, and the second was the effect of decrease in other sectors except pharmaceutical products on vital and economic variables of pharmaceutical products. The required data were obtained and the model parameters were calibrated according to the social accounting matrix of Iran in 2006.
The results associated with simulation demonstrated that the first scenario has increased import, export, drug supply to markets and household consumption, while import, export, supply of product to market, and household consumption of pharmaceutical products would averagely decrease in the second scenario. Ultimately, society welfare would improve in all scenarios.
We presents and synthesizes the CGE model which could be used to analyze trade liberalization policy issue in developing countries (like Iran), and thus provides information that policymakers can use to improve the pharmacy economics.
可计算一般均衡模型是经济分析中的一种强大工具,已被广泛用于评估贸易自由化的影响。本研究的目的是使用可计算一般均衡模型来提供贸易开放对制药行业的影响。
在本研究中,使用可计算一般均衡模型,研究了作为贸易自由化标志的关税降低对伊朗药品关键变量的影响。本研究通过两种情景进行模拟。第一种情景是药品关税降低10%、30%、50%和100%对关键药品变量的影响,第二种情景是除药品外其他部门关税降低对药品重要和经济变量的影响。所需数据已获取,并根据2006年伊朗社会核算矩阵对模型参数进行了校准。
模拟结果表明,第一种情景增加了进口、出口、药品市场供应和家庭消费,而在第二种情景中,药品的进口、出口、市场供应和家庭消费将平均下降。最终,所有情景下社会福利都会得到改善。
我们提出并综合了可用于分析发展中国家(如伊朗)贸易自由化政策问题的可计算一般均衡模型,从而为政策制定者提供可用于改善制药经济学的信息。
