each firm may reset its price only with probability (1-w) each period,independently of the time elapsed since the last adjustment.
each period a measure (1-w) of producers reset their prices, while a fraction w keep their prices unchanged.
pt = wpt-1 + (1- w)xt
w: probability you won't change your price this week
