IMF-FINEX-一个新的宏观经济预测和政策分析的Workhorse模型（英）-2023.11-123页_2mb

FINEX is a semi-structural macroeconomic model designed for forecasting and policy analysis, particularly in countries with imperfect capital mobility and hybrid monetary systems. Its key innovations include:

1. External and Internal Balance Focus: The model explicitly incorporates external balance through current and financial accounts, including foreign exchange reserves and capital flows, and internal balance via demand and supply dynamics in internal markets.

2. Fiscal Policy Integration: It includes detailed fiscal policy instruments (government spending, taxes, transfers) and their interactions with monetary policy, emphasizing both short-term stabilization and long-term debt sustainability.

3. Trend- Based Structure: Variables decompose into trend and gap components (short-term fluctuations), allowing for analysis of both cyclical and long-term dynamics.

4. Flexible Exchange Rate Regimes: Accommodates a range of regimes, from full floats with inflation targeting (IT) to pegged systems, with endogenous foreign exchange interventions.

5. Capital Flow Management: Models administrative barriers (CFMs) and taxes on capital flows to influence capital responsiveness to interest rate differentials.

The model balances simplicity with practicality for forecasting, offering insights into policy interactions (e.g., fiscal-monetary coordination), external balance response to shocks, and vulnerabilities from debt and reserve dynamics. Though inspired by DSGE literature, it maintains a semi-structural framework for accessibility. Further extensions could incorporate financial sector details or address complex multi-country interactions.
