Moving SAMs forward in Time The DSI ‘Dynamic SAM’ (DySAM) describes an instrument based on an existing ‘static’ Social Accounting Matrix (SAM). The DSI Dynamic SAM is designed to support and strengthen national development strategies by analysing the effects of investment planning on the economy. Applications currently being implemented in Southeast Asia and Africa explore the relationship between intensive employment strategies and job creation; and ultimately, poverty reduction. In the context above, and once the disaggregated static SAM has been thoroughly adjusted for balance and consistency across all accounts, the static SAM is transformed into a DySAM by linking the SAM to a dynamic macro-meso control framework. This is handled in the ‘DySAM Data Module’. The DySAM Data Module is specially designed to generate the forward-looking macro-meso controls for the static SAM. The control flows are incorporated into the static SAM as the analyst moves it forward in time. The data sets needed for the DySAM Data Module to generate the forward-looking macro and meso control totals are obtained from official national statistics such as ‘national accounts’, ‘government fiscal accounts’, ‘balance of payments’ and various ‘surveys’. The key attributes of the DySAM are: Establishes the dynamic flows across each account over the desired time period Achieves internal consistency in each year of the projection period Separates DySAM accounts into ‘endogenous’ and ‘exogenous’ categories Generates decomposed Dynamic SAM Multipliers to capture both direct and induced effects and a SAM-based dynamic model for policy simulation for future periods
