  1. A Dynamic Multi-Sectoral General Equilibrium Tax Model of the UK Economy Keshab R Bhattarai Economics Group Business School University of Hull HU6 7RX UK

  2. Contents • Motivation • Research Questions • Model Structure • Calibration • Data set • Tax experiments • Conclusion • Future Scope

  3. Research Questions • What are the dynamic efficiency effects of tax reform ? • How do unanticipated tax changes affect sectoral output, employment and capital formation in the economy? • How do anticipated tax changes affect sectoral output, employment and capital formation? • Does the international openness of capital markets alter the dynamic effects of tax changes? • How to compute a dynamic general equilibrium model for a decentralised economy?

  4. Raw Data (National Accounts, IO, tax, trade, household survey) Adjustments to yield benchmark (micro consistent) data set Replication check Model Structure Functional forms Calibration check Parameters and Elasticities Policy change (tax) specified Compute New Equilibrium Compare to benchmark Equilibrium data Steps for Implementation of a General Equilibrium Model

  5. Institutions Infinitely lived households Profit maximising producers Government Traders Time Horizon 65 years Markets 16 commodities (domestically produced and imports) Labour Sector Specific Capital Use the model Analysis of growth paths (output, employment, investment and capital stock) Dynamic efficiency analysis Capital accumulation Saving-investment- retirement decision Intertemporal redistribution Structure of the Model
