"We inherited a chaotic situation, and in 8 months, we've done a lot," Garcia said after meeting with Wall Street credit agencies in late September in hopes of improving the status of the island's bonds. "We've done everything we had to do."
However, Gustavo Velez, a prominent local economist, said it wasn't clear yet whether the rising costs would do more harm than good.
Next year, the economy is expected to contract by up to 2 percent as Puerto Rico remains burdened by $69 billion in public debt and an unemployment rate of 13.9 percent, higher than any U.S. state.
"It's like a Catch-22," Velez said. "The big question is whether the economy is capable of absorbing the impact of these taxes. .... It's a question we cannot yet answer."
Some critics say the island's public spending is the problem. So far, the new taxes and subsidy cuts haven't seriously pumped up inflation, which was 0.4 percent in June, the newest figure available. Puerto Rico's annualized rate of inflation was 2.6 percent last year.
The new business tax was enacted "to maintain a level of government spending that Puerto Rico's economy cannot sustain," said Priscilla Vazquez, spokeswoman for the Manufacturers Association of Puerto Rico, which is requesting a moratorium on the tax.
Tens of thousands of Puerto Ricans have already left the island for better opportunities elsewhere, including Olivo's two sons who sought new jobs in the U.S. Olivo said he is too old to start a new life with them, noting he's still paying a $750 monthly mortgage and tuition costs with the help from his wife, a social worker.
Meanwhile, Olivo's monthly water bill has more than doubled from $70 to $150, and gas prices have spiked following a new tax that increased a barrel of crude oil from $3 to $9.25. He's adjusted by spending more time at home or walking instead of driving. If forced to use the car, Olivo buys only a couple of gallons (liters) at a time. Three years have passed since he last bought any personal items for himself.
"Those increases have been a disaster," he said. "I can't afford to live in Catano now on Social Security alone. ... I used to make more than $80,000 a year. To go from $80,000 to $0, imagine that."
Such reactions prompted Treasury Secretary Melba Acosta to delay a portion of the oil tax increase in mid-August to give officials time to study its impact on prices, while the state water and sewage company has made concessions to help lower water bills for certain commercial and private consumers. As it stands, residential clients who use up to 35 cubic meters of water a month are paying almost double now. Some commercial clients have seen their bill go up by several thousands of dollars.
"This has definitely had an impact on everyone," said Eugenio Alonso, president and CEO of Consumer Credit Counseling, noting that electricity costs are already on average double those on the mainland. "Business owners are saying, 'I can't do this anymore given the costs.' They declare bankruptcy or simply close."
The new business tax is expected to generate nearly $500 million a year and applies to gross sales of companies generating $1 million or more a year. Another new tax applies to commercial bank transactions.
Wendy Cordova, a 37-year-old widow with five children who relies on Social Security and her income as a hair stylist, said she's struggling to make car payments and pay the medical bills of her 13-year-old daughter, a diabetic. She already sent another daughter to live with her brother in the U.S. to finish high school.
"Everything keeps going up, and people are still making the same salary," she said. "We're going from bad to worse."
Nonprofit organizations across the island, meanwhile, have noted an increase in people seeking help. The concern now is that electric bills will rise next, given that the state power company depends largely on petroleum.
It's another reason Olivo, the chemical engineer, wants a job. He said he had a stroke in May that he blames on financial stress.
As he met with one last recruiter at the job fair, he learned they might need someone to help oversee the reorganization of a nearby factory.
"Do you have immediate availability?" the recruiter asked.
"Yes," Olivo answered. "Right now."
