oil prices are increasing recently due to war and some other reasons. Also i live in a country with exchange rate of 17 againist US Dollars and its getting worse day by day. i drive an old car , usually 10-15km per day approximately. after increasing oil prices , my annual oil consumption cost is almost 1/3 of my car price.
My question is , can increasing cost of oil consumption cause decreasing price for automobiles? we can generalize that question as : can increasing cost-price of a part of a stuff, would decrease the price of that stuff? is there any concept for that situation in economics?
