There is a significant chance the world economy is headed for a recession in 2019, according to Nobel Prize-winning economist Paul Krugman. Market participants are increasingly worried about the prospect of a serious economic downturn in the coming months, with a long-running U.S.-China trade war souring business and consumer sentiment. Most economists, as well as some the world's business elite, agree that economic growth is slowing but policymakers have expressed some hope for a soft landing rather than an outright recession. Speaking at the World Government Summit in Dubai on Sunday, Krugman expressed skepticism about this scenario.

When asked whether investors should expect to see a recession in the coming months, Krugman replied: "I think that there is a quite good chance that we will have a recession late this year (or) next year." Krugman is a professor emeritus of Princeton University's Woodrow Wilson School. He won the Nobel Prize in 2008 for his work on economic geography and identifying international trade patterns.

Krugman said it was unlikely that just "one big thing" would prompt an economic downturn. Instead, a range of economic headwinds would increase the likelihood of a slowdown. He highlighted President Donald Trump's tax cut stimulus as one area of concern, saying the program was "not very effective." Krugman also warned it was "starting to look like the bubble may be deflating" when it comes to tech growth. Citing a broad lack of preparedness among economic policymakers, Krugman said: "The main concern has always been that we don't have an effective response if stuff slows down." "The place that looks really close to recession right now is the euro area," he added.
