May 7 (Reuters) - Insurer Assurant posted more-than-doubled first-quarter profit on Tuesday, helped by higher premiums and investment income.

Growing hopes of a soft landing for the economy and a resilient labor market have encouraged individuals and companies to revive their spending on insurance policies.

Assurant's net earned premiums came in at $2.38 billion in the quarter, up nearly 4.9% from last year.

Shares of the company rose 1.4% in extended trading. The stock has risen 6% so far this year, as of its last close.

Meanwhile, higher interest rates and stronger equity markets have boosted the investment income at insurers, who invest a chunk of their cash in safe-haven assets.

Assurant's net investment income rose to $126.7 million in the quarter from $105.2 million a year earlier.

Atlanta, Georgia-based Assurant provides specialty insurance products and related services globally. Its offerings include renters insurance, vehicle protection services, extended service contracts and lender-placed insurance products, among others.

Assurant's net income rose to $236.4 million, or $4.47 per share, in the three months ended March 31, from $113.6 million, or $2.12 per share, a year earlier. (Reporting by Arasu Kannagi Basil in Bengaluru; Editing by Alan Barona)
