Lecture 9: Vertical Integration and Vertical Restraints

Introduction

Value chain

Vertical relations

supply- demand relations: firms with final customers

upstream firms

downstream firms

intermediary market: between upstream firms and downstream firms

final market: between downstream firms and final customers

Vertical integration

transaction costs theory (in the market)

hold- up problem (example: page 9)

reasons (3)

vertical restraints (p.12): usually upstream companies imposed on downstream companies

efficiency reasons

anti- competitive reasons

Vertical externality

Bilateral monopolies

Double marginalization problem: arise when both upstream and downstream firms have market power => too high final price

example: page 16

vertical integration example: page 21

comparison: vertical separation leads to higher mark- up => worse off

alternative solution: vertical restraints

two- part tariff (p.24)

Horizontal externality

free- riding problem

a model with retailer service (p.31)

effort in providing service

vertical separation

vertical integration

outcome => higher demand curve => higher quantity (even if higher price)

Alternatives to vertical integration (to make p > w)

exclusive territories (ET) (p.39): each of retailers serves half of final customers

resale price maintenance (RPM)

p.40 (no f)

retailer's choice

effects of ET (p.41 - 42)

w < c => will use two- part tariff

below- cost pricing (w < c)

today, it is legal to set a manufacturer suggested retail price (MSRP)

competition between manufacturers (inter- brand competition) (p.49)

Public policy
