A cable operator chooses to bundle or provide programs à la carte by striking a balance between maximizing total surplus and minimizing transfer payments to program providers. We show, using general demand and cost functions, that a cable operator’s decision to bundle maximizes total producer surplus if the cable operator’s bargaining power is sufficiently high, and that a cable operator in a w...

When is the level of entry of buyers or sellers effi cient in markets with search and matching frictions? This paper generalizes the well-known Hosios condition for constrained effi ciency to a wide range of dynamic search and matching environments where the expected match output depends on the market tightness. The generalized Hosios condition is simple and intuitive: entry is constrained effi...

Indonesian rice production has exhibited a positive increasing trend over the years. On other hand, retail prices tend to fluctuate, even though country imported rice. One reason for this is that not all of produced sold market or marketed surplus. The objective study analyse surplus and its determinants. farmers’ survey conducted by Statistics Indonesia in 2014 was utilised. Heckman two-step p...

This paper studies a robust version of the classic surplus extraction problem, in which designer knows only that beliefs each type belong to some set, and designs mechanisms are suitable for all possible set. We derive necessary sufficient conditions full this setting, show these natural set-valued analogues convex independence condition identified by Crémer McLean ( 1985 , 1988 ). is neither g...
