Filmmaker Karan Johar says there are many verticals that need to be observed while paying male and female stars, but he has always paid them equally.

"There is a larger understanding of the economics of movies that sometimes is lesser known by people, who don't understand the business and how it functions. Many times, people make sweeping statements about these things. I'm the first person who'll always want to pay what is completely right, just, justified and valid. I've always done that. But I feel there is a larger understanding of budget versus the verticals that you sell on digital and satellite that are driven by different data," Karan said, when the subject of gender pay gap in Bollywood came up during an interactive media session that Johar hosted along with Kareena Kapoor Khan and Alia Bhatt at MAMI Movie Mela in Mumbai on Sunday evening.
