# 전자상거래 소비자 참여 및 보상 시스템 최적화

## 매 한 줄
> **"매 reward 는 dopamine schedule 의 design"**. e-commerce engagement 는 LTV (lifetime value) 곡선의 변형 문제로, 매 variable-ratio reinforcement + loss-aversion + social proof 의 조합. 2026 현재 매 ML personalization (reinforcement learning bandits) 으로 매 user 마다 다른 reward 를 발사.

## 매 핵심

### 매 4대 lever
- **Frequency**: visit cadence — 매 daily login bonus, streak
- **Depth**: AOV (average order value) — 매 threshold reward, free shipping bar
- **Breadth**: category exploration — 매 cross-sell coupon
- **Retention**: churn prevention — 매 win-back, lapsed user offer

### 매 reward 분류
- **Hedonic**: tier badge, exclusive access — 매 status driver
- **Utilitarian**: point/coupon, cashback — 매 economic driver
- **Social**: referral, leaderboard — 매 viral driver
- **Surprise**: random box, lucky draw — 매 dopamine spike

### 매 응용
1. Subscription churn 감소 — predictive offer 발사.
2. Cart abandonment 회복 — personalized incentive.
3. New-user onboarding — 매 first-week reward sequence.

## 💻 패턴

### Multi-armed bandit reward selector
```typescript
class ContextualBandit {
  private weights: Map<string, number[]> = new Map()

  selectReward(userCtx: UserContext, candidates: Reward[]): Reward {
    const arms = candidates.map(r => ({
      reward: r,
      score: this.predict(userCtx, r),
    }))
    // Thompson sampling
    const sampled = arms.map(a => ({
      ...a,
      sample: a.score + this.gaussianNoise(0.1),
    }))
    return sampled.sort((a, b) => b.sample - a.sample)[0].reward
  }

  update(userCtx: UserContext, reward: Reward, outcome: number) {
    const key = this.featureKey(userCtx, reward)
    const w = this.weights.get(key) ?? [0, 0]
    w[0] += outcome
    w[1] += 1
    this.weights.set(key, w)
  }
}
```

### LTV-aware coupon sizing
```typescript
function couponAmount(user: UserProfile, basket: Cart): number {
  const ltvDecile = user.ltvPercentile
  const marginalLTV = user.predictedLTV - user.realizedLTV
  // 매 high-LTV / low-realized = 매 invest more
  const cap = Math.min(marginalLTV * 0.15, basket.total * 0.25)
  // 매 churn risk multiplier
  const risk = 1 + user.churnProb * 0.5
  return Math.round(cap * risk)
}
```

### Streak / habit loop
```typescript
class StreakEngine {
  async onLogin(userId: string, now: Date) {
    const last = await this.getLastLogin(userId)
    const days = daysBetween(last, now)
    let streak = days === 1 ? (await this.getStreak(userId)) + 1 : 1
    if (streak > 0 && streak % 7 === 0) {
      await this.grantReward(userId, { type: "weekly_streak", multiplier: streak / 7 })
    }
    await this.setStreak(userId, streak)
  }
}
```

### Cart abandonment recovery
```typescript
async function abandonRecovery(cart: Cart, user: User) {
  const elapsed = Date.now() - cart.lastUpdate
  if (elapsed < 1000 * 60 * 30) return // 매 too early
  const offer = await bandit.selectReward(user.context, [
    { type: "free_shipping" },
    { type: "5_percent_off" },
    { type: "loyalty_2x_points" },
  ])
  await sendEmail(user.email, renderRecovery(cart, offer))
  await sendPush(user.deviceTokens, renderPush(offer))
}
```

### Gamified tier progression
```typescript
type Tier = "bronze" | "silver" | "gold" | "platinum"
const TIER_THRESHOLDS: Record<Tier, number> = {
  bronze: 0, silver: 500, gold: 2000, platinum: 10000,
}

function tierProgress(spend: number): { tier: Tier; progress: number; nextAt: number } {
  const tiers: Tier[] = ["bronze", "silver", "gold", "platinum"]
  let cur: Tier = "bronze"
  for (const t of tiers) if (spend >= TIER_THRESHOLDS[t]) cur = t
  const next = tiers[tiers.indexOf(cur) + 1]
  if (!next) return { tier: cur, progress: 1, nextAt: spend }
  const nextAt = TIER_THRESHOLDS[next]
  return { tier: cur, progress: (spend - TIER_THRESHOLDS[cur]) / (nextAt - TIER_THRESHOLDS[cur]), nextAt }
}
```

### Referral viral loop
```typescript
async function referralReward(referrer: string, referee: string, firstOrder: Order) {
  if (firstOrder.total < 30) return // 매 anti-fraud floor
  await grantPoints(referrer, 500)
  await grantCoupon(referee, { value: 10, expiresInDays: 30 })
  await track("referral_completed", { referrer, referee, orderValue: firstOrder.total })
}
```

## 매 결정 기준
| 상황 | Reward type |
|---|---|
| New user (D0-D7) | Welcome bundle + first-purchase bonus |
| Active mid-LTV | Streak + tier progress |
| High-LTV at churn risk | Personalized win-back, hedonic perk |
| Low-LTV, high acquisition cost | Bundle / referral, no deep coupon |
| Cart abandonment | Free shipping (cheap) → coupon (expensive) escalate |

**기본값**: contextual bandit + LTV-capped budget + 매 hedonic + utilitarian mix.

## 🤖 LLM 활용
**언제**: copy generation (개인화 message), reward strategy ideation, A/B test hypothesis.
**언제 X**: 매 real-time bandit decision (latency budget < 50ms) — pre-trained model 로.

## ❌ 안티패턴
- **All-or-nothing coupon**: 매 같은 coupon 모두에게 — margin 폭탄.
- **Streak punishment**: 매 1일 miss 로 reset — 매 user frustration.
- **Dark pattern reward**: 매 hidden cost / forced opt-in — 매 churn 가속.
- **Tier inflation**: 매 너무 빠른 tier-up — 매 status 의미 상실.
- **Reward 의 marginal cost 무시**: 매 LTV 보다 큰 reward — unit economics 붕괴.

## 🧪 검증 / 중복
- Verified (Reichheld Loyalty Effect, Hooked by Nir Eyal, Shopify rewards docs).
- 신뢰도 A.
