BƯỚC 5. THEORY, LITERATURE REVIEW VÀ HYPOTHESES
Bài mẫu: Tourism Uncertainty and Corporate Dividend Policy
Mục tiêu: xây research story quanh hai competing predictions:
$$
TUIuparrow
rightarrow Dividendsdownarrow
$$
versus:
$$
TUIuparrow
rightarrow Dividendsuparrow
$$
và giải thích khi nào mỗi channel có thể dominate.
PHẦN A. LITERATURE STREAMS
Stream 1 — Tourism Uncertainty
Core:
- Ongan et al. (2026).
TUI captures tourism-specific uncertainty, not generic macro uncertainty.
Stream 2 — Uncertainty and Dividend Policy
Core:
- Attig et al. (2021);
- Adra et al. (2023);
- Choi & Park (2024);
- Li et al. (2024);
- Nguyen et al. (2026).
Key fact:
literature gives mixed signs.
Stream 3 — Hospitality / Travel Dividend Policy
Core:
- Canina et al. (2001);
- Kim & Jang;
- Kilincarslan & Demiralay (2021);
- asset-light/dividend hospitality literature.
Key features:
- dividend smoothing;
- profitability;
- leverage;
- size;
- growth opportunities;
- business model.
Stream 4 — Dividend Smoothing and Signaling
Core:
- Lintner (1956);
- Brav et al. (2005).
Stream 5 — Life-Cycle / Agency Dividend Theory
Core:
- Fama & French (2001);
- DeAngelo et al. (2006);
- agency/payout literature.
PHẦN B. PRECAUTIONARY LIQUIDITY THEORY
Tourism uncertainty can cause:
- bookings/demand uncertainty;
- volatile revenue;
- operating cash-flow risk;
- higher external financing need.
Then:
$$
TUIuparrow
rightarrow CashRetentionuparrow
rightarrow DividendPayoutdownarrow
$$
This is especially plausible for:
- airlines;
- hotels;
- high leverage;
- low cash;
- constrained firms.
PHẦN C. SIGNALING THEORY
Under high uncertainty, firms may maintain/increase dividends to:
- signal confidence;
- separate from weak firms;
- reassure investors.
Then:
$$
TUIuparrow
rightarrow Dividendsuparrow
$$
or at least:
$$
DividendCutsdownarrow
$$
for strong firms.
PHẦN D. AGENCY THEORY
Higher uncertainty can increase managerial discretion.
Shareholders may prefer payout to limit free cash flow.
Possible:
$$
TUIuparrow
rightarrow Dividendsuparrow
$$
especially where:
- cash is high;
- growth opportunities low;
- governance weak.
PHẦN E. DIVIDEND SMOOTHING
Lintner-style behavior implies:
- firms do not immediately cut dividends;
- temporary uncertainty may hit repurchases first;
- severe/persistent uncertainty may eventually cause cuts.
Thus timing matters.
PHẦN F. TOURISM-SPECIFICITY
Why should tourism uncertainty matter more for tourism firms?
Tourism businesses often face:
- demand volatility;
- high fixed costs;
- perishable capacity;
- operating leverage;
- event/geopolitical sensitivity;
- seasonal cash flows.
Therefore:
$$
TUItimes TourismExposure
$$
should be economically important.
PHẦN G. RESEARCH GAP
Do not write:
“No one has studied uncertainty and dividends.”
Better gap:
- uncertainty-dividend literature focuses on EPU/GPR, not tourism-specific uncertainty;
- tourism/hospitality dividend literature studies firm characteristics rather than TUI shocks;
- cash dividend and flexible payout channels may respond differently;
- tourism exposure can create a stronger identification design;
- country-specific monthly TUI enables fiscal-year alignment.
PHẦN H. CONTRIBUTIONS
Potential:
- introduce TUI into corporate payout research;
- distinguish tourism-specific uncertainty from EPU/GPR;
- show cash-dividend vs cut/omission/repurchase responses;
- tourism-exposure interaction with Country×Year FE;
- cash-flow/liquidity/signaling channels;
- cross-country tourism dependence.
Use only actual analyses.
PHẦN I. HYPOTHESES
Because literature is mixed, there are two valid approaches.
Option A — Directional precautionary H1
If paper’s theoretical emphasis is liquidity preservation:
H1: Higher tourism uncertainty is associated with lower subsequent corporate dividend payouts.
Option B — Competing hypotheses
H1a: Higher tourism uncertainty reduces corporate dividend payouts through precautionary liquidity preservation.
H1b: Higher tourism uncertainty increases or stabilizes dividend payouts through signaling and agency channels.
Then let data resolve.
For student research, H1a/H1b can be intellectually stronger if literature is clearly mixed.
H2 — Tourism exposure
H2: The relation between tourism uncertainty and dividend policy is stronger among firms with greater tourism exposure.
Direction follows the dominant H1 channel.
H3 — Financial constraints
Under precautionary theory:
H3: The negative relation between tourism uncertainty and dividend payouts is stronger among financially constrained firms.
H4 — Liquidity
H4: Firms with lower cash buffers reduce dividends more strongly when tourism uncertainty rises.
H5 — Dividend cuts / smoothing
H5: Tourism uncertainty increases the likelihood of dividend cuts or omissions more strongly than it changes the dividend-paying status of financially strong firms.
Alternative if signaling result dominates:
modify H3/H4 interpretation after theory review, not after coefficient mining.
PHẦN J. HYPOTHESIS EVIDENCE MATRIX
| H | Theory | Papers | Competing logic | Test |
|---|---|---|---|---|
| H1a | precautionary | Choi/Park; uncertainty liquidity | signaling/agency | main |
| H1b | signaling/agency | Attig; Nguyen; Li | cash retention | main |
| H2 | tourism exposure | TUI + hospitality | broad macro effect | TUI×tourism |
| H3 | financing friction | payout/uncertainty | reassurance | TUI×constraints |
| H4 | liquidity | precautionary | cash-rich agency | TUI×cash |
| H5 | smoothing | Lintner; Brav | severe shocks | cut/omission |
PHẦN K. SAMPLE THEORY PARAGRAPH
Tourism uncertainty creates an ambiguous dividend-policy prediction. On the one hand, tourism-related shocks can reduce demand visibility and raise cash-flow volatility, increasing the value of internal liquidity and encouraging firms to cut or postpone cash distributions. On the other hand, dividends are highly persistent and can serve as signals of financial strength. Managers may therefore maintain or increase dividends during uncertain periods to reassure investors or reduce agency concerns. The broader uncertainty-payout literature reports evidence consistent with both channels, making tourism-specific uncertainty a useful setting in which to examine which mechanism dominates and for which firms.
