62 Channels, B2B, and Go-to-Market Seminar

Interorganizational marketing is the study of how firms reach markets through other firms. Where the consumer-behavior seminar studies the individual buyer and the strategy seminar studies the firm as a whole, this seminar studies the system between firms: the distribution channels that move goods from producer to buyer, the long-lived buyer–seller relationships that govern industrial exchange, the contracts and norms that hold those relationships together, and the sales force that is the firm’s human interface with its market. Together these constitute the firm’s go-to-market architecture—the set of choices about whom to sell through, how to compensate and organize the people who sell, and how to divide the surplus a channel jointly creates.

The intellectual core of the seminar is a single, recurring tension: coordination and governance under opportunism and asset specificity. Two or more self-interested firms can jointly create more value than either can alone, yet each is tempted to appropriate the other’s share, and investments specialized to one relationship—a dedicated plant, a trained sales force, a co-developed product—create quasi-rents that an opportunistic partner can hold up. The field’s canonical results all turn on this problem: independent channel members price too high and sell too little (double marginalization); transaction-specific assets push exchange out of the spot market and into hierarchy or relational governance; sales-force compensation must reconcile the firm’s goals with an agent’s hidden effort. A student who finishes this seminar can read a go-to-market arrangement as an economist reads a contract—identifying the surplus, the holdup hazard, and the governance device that mitigates it—and can estimate the relevant effects with the field’s structural and reduced-form tools.

The seminar matters because most marketing value is delivered, not by firms acting alone, but through these interorganizational systems, and because the governance problems they pose recur wherever exchange is repeated, specialized, and incompletely contractible. The same logic that explains why a manufacturer integrates its sales force explains why a platform writes the contracts it does with its complementors, and why a retailer and a brand fight over a trade promotion.

This chapter develops a tradition the other seminars only sample. The marketing-strategy seminar’s channels-and-governance module (Section 60.14) introduces transaction-cost analysis and relationship marketing as one week among fourteen; the analytical-modeling seminar’s channels weeks (Section 58.6) treat the manufacturer–retailer game as one application of game theory. Here those threads become the spine. The seminar gives the channels/B2B/sales-force tradition the full semester the strategy and analytical seminars cannot, pairing the economic theory of vertical relationships with the empirical literature on relationships, power, franchising, sales organization, organizational buying, and the omnichannel and retailer–manufacturer frontiers.

62.1 Semester arc

The arc moves from economics to organization to dynamics. It opens with the channel as an economic system—why decentralized channels underperform integrated ones, and how coordination is restored—then turns to the institutional question of governance: when exchange should be organized through markets, hierarchies, or relational contracts. Transaction cost economics and its marketing application supply the analytical backbone for Weeks 2 and 3; the relationship-marketing tradition (trust, commitment, and their measured effects) occupies Weeks 4 and 5, adding the behavioral and relational layer that pure economics omits.

The middle of the semester studies the forces and forms of channel relationships—power, conflict, and dependence (Week 6), and the contractual hybrids of franchising and vertical restraints (Week 7)—before turning to the firm’s most expensive go-to-market instrument, the sales force. Three weeks develop sales-force management from agency-theoretic compensation theory (Week 8) through the modern structural and field-experimental evidence on compensation dynamics (Week 9) to the organization, sizing, and effectiveness of the sales function (Week 10). The seminar then steps to the demand side of B2B exchange with organizational-buying theory (Week 11).

The closing arc tracks the field’s live frontiers: multichannel and omnichannel customer management (Week 12); the retailer–manufacturer interface, trade promotions, and retail media (Week 13); and a synthesis week anchored on the make-or-buy meta-analytic evidence that closes the loop back to governance (Week 14). Throughout, the pedagogy is method-forward—each module names the identification problem (governance is chosen, not assigned; compensation responds to selection; pass-through confounds cost and strategic response) that stands between a channel fact and a causal claim.

The reading map uses two tags: [F] = Foundational (canon every channels/B2B scholar should know cold) and [R] = Frontier/Recent (an active research front, refreshed as the literature moves). Each week pairs at least one foundational anchor with one frontier paper. DOIs are reproduced as verified against Crossref; works without a DOI-verified record (older books and proceedings) are named without a link and flagged.

62.2 Week 1 — Channels as economic systems and the coordination problem

Topic. Why a channel of independent firms underperforms an integrated one, and how the members coordinate to recover the lost surplus.

Subtopics. Double marginalization; channel profit maximization; coordinating contracts (two-part tariffs, quantity discounts); the strategic value of decentralization under competition.

Methods. Game-theoretic channel models; demand-and-cost optimization; equilibrium analysis of vertical structure.

Key readings.

Debate. Is asymmetric dependence inherently corrosive, or can a powerful party use restraint to build relational capital? Does high total interdependence offset the costs of asymmetry?

62.8 Week 7 — Franchising and vertical restraints

Topic. Contractual hybrids between market and hierarchy—franchising as a governance form and the economics of vertical restraints.

Debate. Do the canonical transaction-cost predictions hold up meta-analytically, or only under specific operationalizations? What do platform and digital B2B contexts add that the make-or-buy frame misses?

62.16 Foundational vs. frontier at a glance

Foundational core (every channels/B2B student must know): Webster & Wind (1972); Sheth (1973); Williamson (1979); Jeuland & Shugan (1983); McGuire & Staelin (1983); Anderson & Schmittlein (1984); Gaski (1984); Basu, Lal, Srinivasan & Staelin (1985); Brickley & Dark (1987); Dwyer, Schurr & Oh (1987); Heide & John (1988); Coughlan & Sen (1989); Anderson & Narus (1990); Anderson & Weitz (1992); Lafontaine (1992); Morgan & Hunt (1994); Heide (1994); Kumar, Scheer & Steenkamp (1995); Rindfleisch & Heide (1997); Ailawadi, Neslin & Gedenk (2001); Homburg, Workman & Jensen (2002); Zoltners & Sinha (2005); Ansari, Mela & Neslin (2008).

Frontier / actively updated (refresh each edition): Besanko, Dubé & Gupta (2005); Palmatier, Dant, Grewal & Evans (2006); Geyskens, Steenkamp & Kumar (2006); Palmatier, Dant & Grewal (2007); Workman, Homburg & Jensen (2003); Misra & Nair (2011); Chung, Steenburgh & Sudhir (2014); Verhoef, Kannan & Inman (2015). The split is pedagogical, not chronological: a 1979 paper is foundational because the field still reasons in its terms, while a 2006 meta-analysis is “frontier” because its generalizations are still being executed and contested.

62.17 How this chapter expands

The weekly map is a backbone, not a ceiling. The chapter is designed to grow along four axes.

A structural-estimation companion per sales-force week. Weeks 8–9 already pair agency theory with structural field evidence; a future edition should add a short methods note—dynamic discrete choice, the estimation of agents’ beliefs and discount factors, and field-experiment design—so the chapter teaches how the modern compensation literature identifies its effects, not only what it found.
A platforms and two-sided-markets module. The make-or-buy frame (Week 14) extends naturally to platform governance, where the “channel” is a marketplace and the holdup hazard runs between the platform and its complementors; this connects to the platforms seminar and deserves its own week as the literature matures.
B2B digital, sales technology, and AI-enabled selling. Frontline-technology adoption, CRM and sales-force automation, and generative-AI selling assistants are reshaping Weeks 9–11; each should enter as foundational anchor plus frontier paper plus an identification debate about selection into adoption.
An internationalized governance base. The TCE/relational canon is largely US-centric; comparative work on guanxi, keiretsu, and distributor relationships in emerging markets would broaden how programs weight formal vs. relational governance.

62.17.1 Channel coordination and double marginalization

The seminar’s opening economic result is best seen in a compact channel model. A single manufacturer sells through a single retailer to final consumers whose demand is linear, \[ q = a - b\,p, \qquad a,b>0, \tag{62.1}\] where $p$ is the retail price and $q$ the quantity sold. Production costs the manufacturer a constant $c$ per unit; the retailer adds no marginal cost beyond the wholesale price $w$ it pays. The integrated benchmark is the price a single vertically integrated firm would set to maximize total channel profit $\pi = (p-c)\,q$. Substituting demand and taking the first-order condition, \[ \max_{p}\ (p-c)(a-b\,p) \quad\Longrightarrow\quad p^{\*} = \frac{a + b\,c}{2b}, \tag{62.2}\] with channel-optimal quantity $q^{\*} = (a - b c)/2$ and total profit $\pi^{\*} = (a-bc)^2/(4b)$. This is the surplus the channel can earn when a single decision maker internalizes the full margin.

Now decentralize. The two firms price independently, each maximizing its own profit. The retailer takes the wholesale price $w$ as given and chooses $p$ to maximize $(p-w)(a-b p)$, yielding the retail reaction \[ p(w) = \frac{a + b\,w}{2b}, \tag{62.3}\] so the retailer marks up over its own cost $w$ exactly as the integrated firm marks up over $c$. The manufacturer, anticipating this, chooses $w$ to maximize $(w-c)\,q\big(p(w)\big) = (w-c)\cdot\frac{a-b w}{2}$, which gives the wholesale price \[ w^{\dagger} = \frac{a + b\,c}{2b}. \tag{62.4}\] Propagating $w^{\dagger}$ through the retailer’s reaction Equation 62.3 yields the decentralized retail price \[ p^{\dagger} = \frac{3a + b\,c}{4b} \;>\; p^{\*}, \qquad q^{\dagger} = \frac{a - b c}{4} \;<\; q^{\*}. \tag{62.5}\] The retail price is too high and the quantity too low: each firm marks up over its own marginal cost, so the margin is taken twice. This is double marginalization. The combined channel profit under decentralization is \[ \pi^{\dagger}_{M} + \pi^{\dagger}_{R} = \frac{(a-bc)^2}{8b} + \frac{(a-bc)^2}{16b} = \frac{3(a-bc)^2}{16b} \;<\; \pi^{\*} = \frac{(a-bc)^2}{4b}, \tag{62.6}\] a strict loss of $(a-bc)^2/16b$—one quarter of the integrated profit—relative to coordination doi:10.1287/mksc.2.3.239.

The loss is not a deadweight inevitability of separate ownership; it is a contracting failure that the right instrument repairs. A two-part tariff sets the wholesale price at marginal cost, $w = c$, so the retailer faces the integrated firm’s problem and sets $p = p^{\*}$, and the manufacturer extracts its share through a fixed franchise fee $F$: \[ w = c, \qquad F \le \pi^{\*} = \frac{(a-bc)^2}{4b}. \tag{62.7}\] With $w=c$ the retailer’s marginal incentive is aligned with the channel’s, the double markup vanishes, and the lump-sum fee $F$ divides the restored surplus without distorting the price. A quantity discount achieves the same end through a nonlinear wholesale schedule $w(q)$ whose marginal price equals $c$ at the coordinated volume, rewarding the retailer for expanding output to $q^{\*}$ rather than restricting it. Both devices coordinate the channel by making the downstream firm’s marginal cost equal the true marginal cost of production, which is precisely the condition the integrated firm satisfies. The general lesson generalizes well beyond linear demand: whenever successive margins stack, a coordinating contract that restores marginal-cost pricing downstream and reallocates surplus through a fixed transfer recovers the joint optimum—though, as Week 1’s debate notes, a manufacturer facing a competing channel may rationally decline to coordinate, using decentralization as a strategic commitment to soften price competition doi:10.1287/mksc.2.2.161.

62.18 Key Takeaways

Interorganizational marketing studies the firm’s go-to-market system—channels, buyer–seller relationships, governance, and the sales force—and its central tension is coordination and governance under opportunism and asset specificity; this seminar develops the tradition the strategy (Section 60.14) and analytical (Section 58.6) seminars only sample.
A decentralized channel underperforms an integrated one through double marginalization (Equation 62.5); coordinating contracts—two-part tariffs
1. and quantity discounts—restore the joint optimum by making the retailer’s marginal cost equal the true marginal cost, while McGuire & Staelin show decentralization can also be a strategic commitment under competition.
Transaction cost economics (Williamson; Anderson & Schmittlein; Rindfleisch & Heide) explains vertical boundaries from asset specificity, uncertainty, and frequency, and the relational tradition (Heide; Dwyer, Schurr & Oh; Morgan & Hunt; Palmatier et al.) adds the trust-and-commitment layer that pure cost minimization omits—the two are tested head-to-head by Week 5’s comparative work.
Sales-force management runs from agency-theoretic compensation (Basu et al.; Coughlan & Sen) to modern dynamic structural and field-experimental evidence (Misra & Nair; Chung, Steenburgh & Sudhir) and to the organization, sizing, and effectiveness of the selling function (Zoltners & Sinha; key-account management).
Across every module the identification problem is that governance, compensation, and channel structure are chosen, not assigned, so credible designs model selection, exploit shocks, or run experiments; the make-or-buy meta-analysis (Geyskens, Steenkamp & Kumar) closes the semester by asking which transaction-cost predictions actually replicate.

# Channels, B2B, and Go-to-Market Seminar {#sec-channels-b2b-seminar} *Interorganizational marketing* is the study of how firms reach markets through other firms. Where the consumer-behavior seminar studies the individual buyer and the strategy seminar studies the firm as a whole, this seminar studies the *system between firms*: the distribution channels that move goods from producer to buyer, the long-lived buyer–seller relationships that govern industrial exchange, the contracts and norms that hold those relationships together, and the sales force that is the firm's human interface with its market. Together these constitute the firm's *go-to-market* architecture—the set of choices about whom to sell through, how to compensate and organize the people who sell, and how to divide the surplus a channel jointly creates. The intellectual core of the seminar is a single, recurring tension: **coordination and governance under opportunism and asset specificity**. Two or more self-interested firms can jointly create more value than either can alone, yet each is tempted to appropriate the other's share, and investments specialized to one relationship—a dedicated plant, a trained sales force, a co-developed product—create quasi-rents that an opportunistic partner can hold up. The field's canonical results all turn on this problem: independent channel members price too high and sell too little (double marginalization); transaction-specific assets push exchange out of the spot market and into hierarchy or relational governance; sales-force compensation must reconcile the firm's goals with an agent's hidden effort. A student who finishes this seminar can read a go-to-market arrangement as an economist reads a contract—identifying the surplus, the holdup hazard, and the governance device that mitigates it—and can estimate the relevant effects with the field's structural and reduced-form tools. The seminar matters because most marketing value is delivered, not by firms acting alone, but through these interorganizational systems, and because the governance problems they pose recur wherever exchange is repeated, specialized, and incompletely contractible. The same logic that explains why a manufacturer integrates its sales force explains why a platform writes the contracts it does with its complementors, and why a retailer and a brand fight over a trade promotion. This chapter develops a tradition the other seminars only sample. The marketing-strategy seminar's channels-and-governance module (@sec-strategy-week-channels) introduces transaction-cost analysis and relationship marketing as one week among fourteen; the analytical-modeling seminar's channels weeks (@sec-analytical-week05) treat the manufacturer–retailer game as one application of game theory. Here those threads become the spine. The seminar gives the channels/B2B/sales-force tradition the full semester the strategy and analytical seminars cannot, pairing the economic theory of vertical relationships with the empirical literature on relationships, power, franchising, sales organization, organizational buying, and the omnichannel and retailer–manufacturer frontiers. ## Semester arc The arc moves from **economics to organization to dynamics**. It opens with the channel as an economic system—why decentralized channels underperform integrated ones, and how coordination is restored—then turns to the institutional question of *governance*: when exchange should be organized through markets, hierarchies, or relational contracts. Transaction cost economics and its marketing application supply the analytical backbone for Weeks 2 and 3; the relationship-marketing tradition (trust, commitment, and their measured effects) occupies Weeks 4 and 5, adding the behavioral and relational layer that pure economics omits. The middle of the semester studies the *forces and forms* of channel relationships—power, conflict, and dependence (Week 6), and the contractual hybrids of franchising and vertical restraints (Week 7)—before turning to the firm's most expensive go-to-market instrument, the **sales force**. Three weeks develop sales-force management from agency-theoretic compensation theory (Week 8) through the modern structural and field-experimental evidence on compensation dynamics (Week 9) to the organization, sizing, and effectiveness of the sales function (Week 10). The seminar then steps to the *demand side* of B2B exchange with organizational-buying theory (Week 11). The closing arc tracks the field's live frontiers: multichannel and omnichannel customer management (Week 12); the retailer–manufacturer interface, trade promotions, and retail media (Week 13); and a synthesis week anchored on the make-or-buy meta-analytic evidence that closes the loop back to governance (Week 14). Throughout, the pedagogy is method-forward—each module names the identification problem (governance is *chosen*, not assigned; compensation responds to selection; pass-through confounds cost and strategic response) that stands between a channel fact and a causal claim. The reading map uses two tags: **[F] = Foundational** (canon every channels/B2B scholar should know cold) and **[R] = Frontier/Recent** (an active research front, refreshed as the literature moves). Each week pairs at least one foundational anchor with one frontier paper.

The split is pedagogical, not chronological: a 1979 paper is foundational because the field still reasons in its terms, while a 2006 meta-analysis is "frontier" because its generalizations are still being executed and contested. ## How this chapter expands {#sec-chan-expands} The weekly map is a backbone, not a ceiling. The chapter is designed to grow along four axes. 1. **A structural-estimation companion per sales-force week.** Weeks 8–9 already pair agency theory with structural field evidence; a future edition should add a short methods note—dynamic discrete choice, the estimation of agents' beliefs and discount factors, and field-experiment design—so the chapter teaches *how* the modern compensation literature identifies its effects, not only what it found. 2. **A platforms and two-sided-markets module.** The make-or-buy frame (Week 14) extends naturally to platform governance, where the "channel" is a marketplace and the holdup hazard runs between the platform and its complementors; this connects to the platforms seminar and deserves its own week as the literature matures. 3. **B2B digital, sales technology, and AI-enabled selling.** Frontline-technology adoption, CRM and sales-force automation, and generative-AI selling assistants are reshaping Weeks 9–11; each should enter as foundational anchor plus frontier paper plus an identification debate about selection into adoption. 4. **An internationalized governance base.** The TCE/relational canon is largely US-centric; comparative work on guanxi, keiretsu, and distributor relationships in emerging markets would broaden how programs weight formal vs. relational governance. ### Channel coordination and double marginalization {#sec-chan-worked} The seminar's opening economic result is best seen in a compact channel model. A single **manufacturer** sells through a single **retailer** to final consumers whose demand is linear, $$ q = a - b\,p, \qquad a,b>0, $$ {#eq-chan-demand} where $p$ is the retail price and $q$ the quantity sold. Production costs the manufacturer a constant $c$ per unit; the retailer adds no marginal cost beyond the wholesale price $w$ it pays. The **integrated benchmark** is the price a single vertically integrated firm would set to maximize total channel profit $\pi = (p-c)\,q$. Substituting demand and taking the first-order condition, $$ \max_{p}\ (p-c)(a-b\,p) \quad\Longrightarrow\quad p^{\*} = \frac{a + b\,c}{2b}, $$ {#eq-chan-integrated} with channel-optimal quantity $q^{\*} = (a - b c)/2$ and total profit $\pi^{\*} = (a-bc)^2/(4b)$. This is the surplus the channel *can* earn when a single decision maker internalizes the full margin. Now **decentralize**. The two firms price independently, each maximizing its own profit. The retailer takes the wholesale price $w$ as given and chooses $p$ to maximize $(p-w)(a-b p)$, yielding the retail reaction $$ p(w) = \frac{a + b\,w}{2b}, $$ {#eq-chan-retail-foc} so the retailer marks up over its own cost $w$ exactly as the integrated firm marks up over $c$. The manufacturer, anticipating this, chooses $w$ to maximize $(w-c)\,q\big(p(w)\big) = (w-c)\cdot\frac{a-b w}{2}$, which gives the wholesale price $$ w^{\dagger} = \frac{a + b\,c}{2b}. $$ {#eq-chan-wholesale} Propagating $w^{\dagger}$ through the retailer's reaction @eq-chan-retail-foc yields the decentralized retail price $$ p^{\dagger} = \frac{3a + b\,c}{4b} \;>\; p^{\*}, \qquad q^{\dagger} = \frac{a - b c}{4} \;<\; q^{\*}. $$ {#eq-chan-dm} The retail price is *too high* and the quantity *too low*: each firm marks up over its own marginal cost, so the margin is taken twice. This is **double marginalization**. The combined channel profit under decentralization is $$ \pi^{\dagger}_{M} + \pi^{\dagger}_{R} = \frac{(a-bc)^2}{8b} + \frac{(a-bc)^2}{16b} = \frac{3(a-bc)^2}{16b} \;<\; \pi^{\*} = \frac{(a-bc)^2}{4b}, $$ {#eq-chan-profit-loss} a strict loss of $(a-bc)^2/16b$—one quarter of the integrated profit—relative to coordination [doi:10.1287/mksc.2.3.239](https://doi.org/10.1287/mksc.2.3.239). The loss is *not* a deadweight inevitability of separate ownership; it is a **contracting failure** that the right instrument repairs. A **two-part tariff** sets the wholesale price at marginal cost, $w = c$, so the retailer faces the integrated firm's problem and sets $p = p^{\*}$, and the manufacturer extracts its share through a fixed franchise fee $F$: $$ w = c, \qquad F \le \pi^{\*} = \frac{(a-bc)^2}{4b}. $$ {#eq-chan-twopart} With $w=c$ the retailer's marginal incentive is aligned with the channel's, the double markup vanishes, and the lump-sum fee $F$ divides the restored surplus without distorting the price. A **quantity discount** achieves the same end through a nonlinear wholesale schedule $w(q)$ whose marginal price equals $c$ at the coordinated volume, rewarding the retailer for expanding output to $q^{\*}$ rather than restricting it. Both devices coordinate the channel by making the *downstream* firm's marginal cost equal the *true* marginal cost of production, which is precisely the condition the integrated firm satisfies. The general lesson generalizes well beyond linear demand: whenever successive margins stack, a coordinating contract that restores marginal-cost pricing downstream and reallocates surplus through a fixed transfer recovers the joint optimum—though, as Week 1's debate notes, a manufacturer facing a *competing* channel may rationally decline to coordinate, using decentralization as a strategic commitment to soften price competition [doi:10.1287/mksc.2.2.161](https://doi.org/10.1287/mksc.2.2.161). ## Key Takeaways - Interorganizational marketing studies the firm's **go-to-market system**—channels, buyer–seller relationships, governance, and the sales force—and its central tension is coordination and governance under opportunism and asset specificity; this seminar develops the tradition the strategy (@sec-strategy-week-channels) and analytical (@sec-analytical-week05) seminars only sample. - A decentralized channel underperforms an integrated one through **double marginalization** (@eq-chan-dm); coordinating contracts—two-part tariffs (@eq-chan-twopart) and quantity discounts—restore the joint optimum by making the retailer's marginal cost equal the true marginal cost, while McGuire & Staelin show decentralization can also be a strategic commitment under competition. - **Transaction cost economics** (Williamson; Anderson & Schmittlein; Rindfleisch & Heide) explains vertical boundaries from asset specificity, uncertainty, and frequency, and the relational tradition (Heide; Dwyer, Schurr & Oh; Morgan & Hunt; Palmatier et al.) adds the trust-and-commitment layer that pure cost minimization omits—the two are tested head-to-head by Week 5's comparative work. - **Sales-force management** runs from agency-theoretic compensation (Basu et al.; Coughlan & Sen) to modern dynamic structural and field-experimental evidence (Misra & Nair; Chung, Steenburgh & Sudhir) and to the organization, sizing, and effectiveness of the selling function (Zoltners & Sinha; key-account management). - Across every module the identification problem is that governance, compensation, and channel structure are **chosen, not assigned**, so credible designs model selection, exploit shocks, or run experiments; the make-or-buy meta-analysis (Geyskens, Steenkamp & Kumar) closes the semester by asking which transaction-cost predictions actually replicate.
