As concerns grow over the United States involvement in Iran, concerns are increasing about how this may negatively impact local economies in the U.S. UNLV Associate Professor of Economics, Dr. Nicholas Irwin, suggests that the global oil market, along with global shipping, could also be impacted by the ongoing conflict in Iran and some shipping routes may have to be changed, leading to increased costs. The increase in global oil prices could start with increased fuel prices, but this is only the beginning of the process, according to a U.s. Public Affairs Consultant, Tal Eslick, warns that the involvement could lead to a trickle-down effect on American budgets. Meanwhile, Las Vegas, which relies heavily on tourism, may already be seeing a decrease in tourism.
