چکیده
در طول چند دهه اخیر، دیدگاه‌های متفاوتی در خصوص اثر افزایش حداقل دستمزد بر تورم وجود داشته است. هدف این مطالعه بسط مطالعات تجربی اخیر در خصوص تاثیر حداقل دستمزد بر تورم با ملاحظه این نکته است که ممکن است اثرگذاری حداقل دستمزد بر تورم به شرایط رونق و رکود اقتصادی وابسته باشد. در چارچوب نظریه تورم فشار هزینه، افزایش حداقل دستمزد با اثرات مستقیم و غیر مستقیم از طریق یک سازوکار چند مرحله‌ای باعث افزایش هزینه تولید و تورم می‌شود. شدت اثرگذاری این سازوکار می‌تواند به موقعیتی که اقتصاد کشور در مراحل دوران تجاری قرار دارد، وابسته باشد. برای آزمون این فرضیه از مدل چرخشی مارکوف برای بررسی اثرحداقل دستمزد بر تورم تحت تاثیرشرایط رونق و رکود اقتصادی در ایران طی دوره 1352 تا 1392 استفاده شده است. مقایسه تخمین مدل تک رژیمی با مدل دو رژیمی نتایج مشابهی را برای دوره مورد بررسی نشان می‌دهند. مهمترین نتیجه تحقیق بیانگر آن است که صرف‌نظر از شرایط اقتصادی، افزایش حداقل دستمزد اثر معناداری بر تورم نداشته است. براساس نتایج به دست آمده، در هر دو مدل افزایش تورم تاثیر معناداری بر حداقل دستمزد داشته است . به طور خلاصه نتایج این مطالعه با نشان دادن اینکه اثربخشی حداقل دستمزدها بر تورم به شرایط سیکل تجاری وابسته نیست یافته تجربی جدیدی برای رابطه حداقل دستمزد و تورم در اقتصاد ایران فراهم می‌کند. مهمترین توصیه سیاستی حاصل از این مطالعه این است که همراه با افزایش تورم در کشور، افزایش متناسب حداقل دستمزد ضروری است تا کاهش حداقل دستمزد حقیقی نیروی کار جبران گردد، بدون این که نگرانی برای آثار تورمی آن وجود داشته باشد.

چکیده English

Over past decades there have been conflicting views on whether raising the minimum wage increases inflation. This study updates and expands earlier research into this subject and fills a void in the empirical literature by studying that the impacts of the minimum wage on inflation could be altered in the different economic situations. In framework of cost push inflation theoretical background, the direct and indirect effects of minimum wage changes on wage and inflation can be seen as taking place in several stages. The overall wage inflation outcome can, of course, also depend on the position of the economy in a particular stage of the business cycle. To examine this hypothesis, we used a Markov regime-switching model to study the impact of minimum wage increases on inflation over expansion or recession situations in Iran during the 1973- 2013 period. The comparison between a single-regime and regime shifting models provides the similar results for the sample period. The most important finding of this study is that there is no significant impact of minimum wage increases on inflation regardless of economic situations. However, the results show that the inflation shock positively impacts minimum wage in both models. In sum, our results provide a significant contribution to the empirical literature by verifying that the effectiveness of minimum wage on inflation is not dependent on the business cycle economic situation. The main policy implication for Iran's economy deriving from this study is that the minimum wages should be increased to compensate wage workers for real-wage decrease caused by inflation, without any concern about its inflationary effects.
