The other thing to consider is to switch from a per diem basis to a refund basis. That is Ministers should first make their expenses and then get refunded afterwards. A third suggestion would be to give the per diem in rupees so that we align the interest of our globe-trotters with that of the common woman. These might have, had they been in place for at least a decade, restrained one ex-central banker from blurting out dim-witted prescriptions about depreciating our rupee with an annoying frequency.
