We ask economists for their expertise all the time on The Indicator, so why not their tips on love? On our final installment of Love Week, we ask economist Tim Harford to answer listeners' relationship quandaries, from paying for a first date to alternatives to saying, 'I love you.' Thanks to Grant-Lee Phillps for composing our Love Week theme song and Kaitlin Brito for artwork.
