### Summary
- Uses a computable general equilibrium model of the economy of Trinidad and Tobago to assess effects of:
  - trade liberalization; and
  - terms-of-trade shocks.
- Focuses on impacts on the real exchange rate and the overall fiscal position of the government.
- Evaluates implications of alternative tax policies designed to offset the increase in the budget deficit of the central government resulting from both types of external sector shocks.

### Model and methodology
- Computable general equilibrium (CGE) model calibrated to the economy of Trinidad and Tobago.
- Scenarios analyzed include trade liberalization and terms-of-trade deterioration/shocks.
- Model outputs used to trace effects on:
  - real exchange rate;
  - import volumes and importable goods;
  - exportable goods and world price PWM; and
  - government budget balance.

### Key findings
- External sector shocks (trade liberalization and terms-of-trade shocks) materially affect the real exchange rate.
- Both types of shocks lead to an increase in the budget deficit of the central government.
- Cross-price effects and consumer demand responses are important channels mediating real exchange rate and trade volume adjustments.
- Tariffs, value-added tax, and other tax instruments interact with trade reform to influence fiscal outcomes.

### Policy implications and recommendations
- Alternative tax policies can be designed to offset the increase in the central government budget deficit caused by external shocks.
- Tax policy design should consider:
  - the structure of tariffs and their reform under trade liberalization;
  - potential roles for value-added tax adjustments; and
  - distributional and sectoral impacts via traded and nontraded goods channels.
- Policymakers need to account for real exchange rate movements when choosing fiscal responses to external shocks.
