The IMF Working Papers series is designed to make IMF staff research available to a wide audience. Almost 300 Working Papers are released each year, covering a wide range of theoretical and analytical topics, including balance of payments, monetary and fiscal issues, global liquidity, and national and international economic developments.
This paper describes a small macroeconomic model based on a representative industrial-country block of MULTIMOD, the IMF’s multi-country simulation model. REPMOD is designed to provide a more flexible and accessible tool for analysis by individual country desks than the full version of MULTIMOD. It also allows the construction of model-consistent baseline paths, in addition to conventional shock-minus-control experiments. After discussing the model’s general structure and properties, some distinctive aspects are illustrated via simulations that explore the implications of Japan’s liquidity trap.
