The Senate gave final approval Wednesday to legislation granting President Obama enhanced power to negotiate major trade agreements. The vote kept on track an ambitious agenda to complete a free trade agreement, known as the Trans-Pacific Partnership, that would open markets in 12 countries from Canada and Chile to Australia and Japan. About one-third of all goods exported from Massachusetts, more than $9 billion worth, go to Trans-Pacific Partnership countries, according to trade statistics. The state’s leading industries and exporters — technology and life sciences companies — would benefit from more open markets, analysts and industry officials said.

The influx of new overseas flights into Boston is producing bottlenecks at Logan Airport’s international terminal, with travelers increasingly facing waits to clear US Customs that can stretch to several hours. The growing delays prompted the Massachusetts congressional delegation on Thursday to send a letter to the Department of Homeland Security complaining about “unacceptable” wait times and questioning why Logan has not received additional agents, as have other airports around the country. “These wait times are not just an inconvenience to travelers but also negatively affect economic activity in the region,” the letter said. Customs and Border Protection declined to comment.

JetBlue Airways on Tuesday announced that its new first-class cabin will be available on flights between Logan International Airport and the West Coast starting in March. Logan’s biggest airline will begin offering its premium “Mint” seating on up to three round-trip flights each day between Boston and San Francisco, and add up to three more daily trips to Los Angeles next fall. For years, the low-cost carrier offered a single coach-only cabin. Logan will become the fourth US airport to offer the premium class. The Mint cabin offers 16 seats that recline into fully flat beds, including four private suites.

Bristol-Myers Squibb Co. said it will open a drug discovery center in Kendall Square in early 2018 with 300 workers to focus on genetic diseases. The new site at 100 Binney St. will include about 100 researchers from a Waltham lab slated to close. The center’s other 200 employees may include many accepting transfers from a Wallingford, Conn., site also to be shut down as part of a broader Bristol-Myers restructuring. Bristol-Myers joins a parade of biopharmaceutical companies that have recently established or expanded operations in Cambridge. Drug makers Pfizer Inc., Sanofi SA, and Novartis AG have all consolidated research operations at their Cambridge sites.

One of Boston’s biggest African-American-owned development firms wants to build a $200 million tower that would be the tallest building in Roxbury. Executives at Long Bay Management Co., owned by developer Ken Guscott and his brothers, have met with city officials to discuss constructing a 25-story building that would include 16 stories of middle-class housing across from Dudley Square. More than 100 rental apartments and a smaller number of condos are planned. The building also would offer retail and office space, and would occupy almost an entire block bounded by Shawmut Avenue, Roxbury Street, Washington Street, and Marvin Street.

Massachusetts home sales fell in May, compared with the same month last year, as a tight supply of properties on the market continued to frustrate buyers, according to analysts and industry officials. Sales of single-family homes dropped nearly 3 percent in May, the Warren Group, a Boston real estate tracking firm, reported Tuesday. The median single-family home price, $340,000 in May, was unchanged from 2014. Separately, the Joint Center for Housing Studies at Harvard University reported that the percentage of US households owning their homes slid last year to 64.5 percent, the lowest level in two decades. In Greater Boston, according to the latest data, the homeownership rate was 60.9 percent, down from 64.2 percent prior to the recession.

US consumer spending surged in May with the biggest monthly increase in nearly six years — a sign of stronger economic growth ahead. The Commerce Department said Thursday that consumer spending rose 0.9 percent last month, up from a revised 0.1 percent increase in April. May spending registered the biggest gain since August 2009, an indication that the positive effects of stronger hiring and cheaper gasoline are starting to ripple through the economy. In the first three months of the year, the US economy contracted, but not as much as previously estimated, the Commerce Department said. The economy shrank at an annual rate of 0.2 percent from January through March, better than last month’s estimate of a 0.7 percent decrease.

One of the state’s largest ambulance operators sued the City of Quincy for what it called a biased and illegal decision to end its contract and choose a new vendor for emergency medical services. Quincy-based Fallon Ambulance Service, which has provided services to the city for 18 years, filed a suit in Norfolk Superior Court in Dedham to block the city from switching to Brewster Ambulance Service of Hyde Park on July 1. The contract for responding to 911 emergency calls in Quincy, a city of more than 90,000 people, is worth about $5 million, or 9 percent of Fallon’s annual revenue. City officials and Brewster, which also was named in the suit, deny the claims.

Massachusetts is known as a liberal haven — home of the Kennedys and birthplace of same-sex marriage. But at least three right-leaning outlets — two talk-radio stations and an online newspaper — are setting up shop in this bluest of blue states, knowing not everyone will listen or read but betting that the overlooked, red-tinged minority will form a loyal following. The sudden sprouting of conservative news and commentary in Massachusetts fits a national trend toward media fragmentation, with Republican-friendly content among the most common splinters, industry specialists say.
