Customers look around luxury bags at a shopping mall in Beijing, China, September 23, 2015. Rising vacancy rates and plummeting rents are increasingly common in Chinese malls and department stores, despite official data showing a sharp rebound in retail sales that helped the world's second-largest economy beat expectations in the third quarter. The answer to that apparent contradiction lies in the rising competition from online shopping and government purchases possibly boosting retail statistics. Add poorly managed properties into the equation and the empty malls aren't much of a surprise. Picture taken September 23, 2015. REUTERS/Kim Kyung-Hoon

Bazileo Hernandez (R) fills out a job application at a motel while searching for jobs in Williston, North Dakota January 23, 2015. A week after arriving in Williston from California, Williamson and his friends were still looking for steady work. Like so many before them, Terra Green, Jeff Williamson and Bazileo Hernandez came to North Dakota's oil country seeking a better life. They just came too late. Itinerant, unskilled workers could as recently as last spring show up in the No. 2 U.S. oil producing state and vie for salaries north of $100,000 per year with guaranteed housing. The steep drop in oil prices has changed that. After trying unsuccessfully for over a month to find work, the friends decided to leave Williston.

A man buys goods from a counter at a consumer corporation affiliated to the Ministry of Internal Trade in Damascus February 22, 2015. The Syrian government does not expect to import wheat this year because domestic grain supplies will be boosted by heavy rainfall and wider control over farmland, a minister said. Hassan Safiyeh, the minister of internal trade and consumer protection, also told Reuters that a credit line extended by Iran to its Syrian ally had been unaffected by the collapse in world oil prices and fuel imports continued. Safiyeh's ministry oversees the provision of heavily subsidised foodstuffs and fuel to Syrians in areas of government control, making it a vital arm of the state in a country about to enter its fifth year of conflict. The state has lost control of oilfields and wide areas of agricultural land seized by insurgents during the conflict that has devastated the economy.
