Quarterly Forecasting Model with Clark's Investment Accelerator

Title	Quarterly Forecasting Model with Clark's Investment Accelerator
Authors	V. P. Mishchenko¹ ¹Lomonosov Moscow State University
Annotation	To model macroeconomic equilibrium, we will consider a model of a small open economy based on the semi-structural quarterly forecast model (QPM), adding Clarke's investment accelerator to the model. This allows us to evaluate the investment process in Russia from the point of view of its dynamics with respect to key macroeconomic variables such as the market for goods and services, money market, foreign exchange market and external market for goods.
Keywords	quarterly forecast model, investments, investment process, demand shock, supply shock.
