A comparative analysis of the structure of the informa tion economy as a function of the stage of development is explored using input-output modelling and data from Australia and Papua New Guinea. The structure of the information-economy and macro-economy implications is analysed using various multipliers, linkage and leakage measures. The empirical results of the study provide insights on: (i) the sectoral gearing ratios within the information and macro-economies; (ii) the causal mechanisms between information growth and development; and (iii) the 'informa tion dependency' of developing economies on developed economies.
