"Gay Penalty"
Two US economists, Christopher Carpenter and Samuel Eppink, discovered that full-time employed gay men in the United States earn, on average, 10 percent more money than straight men with similar jobs.
The change has demonstrated a positive tendency compared to previous years when gay men had a lower salary than similarly employed straight men.

Here, however, the situation has not changed much, as lesbians, on average, have earned more money than straight women for a long time now.
Bisexual men and women were found to have lower salaries than both their homosexual and heterosexual colleagues.
Although the economists couldn't name the exact reasons behind the increase in salaries for gay men, they assumed that the trend might be related to a positive change in attitudes toward homosexuals, which was reflected in a corresponding change in their pays.
Another assumption is that gay men may have always had similar or even higher salaries compared to straight men, but most of them hadn't openly talk about their sexual orientation and thus were not available to scientists.
