Give Credit Where Credit is Due: Tracing Value Added in Global Production Chains

This paper provides both a conceptual framework for decomposing a countrys gross exports into value-added components by source and a new bilateral database on value-added trade. Our parsimonious framework integrates all previous measures of vertical specialization and value-added trade in the literature. To illustrate the potential of the decomposition, we present a number of applications including re-computing revealed comparative advantages and constructing an index to describe whether a country-sector is likely in the upstream or downstream of global production chains.

The MONASH Style of Computable General Equilibrium Modeling: A Framework for Practical Policy Analysis

MONASH models are descended from Johansens 1960 model of Norway. The first MONASH model was ORANI, used in Australias tariff debate of the 1970s. Johansens influence combined with institutional arrangements in their development gave MONASH models distinctive characteristics, facilitating a broad range of policy-relevant applications. MONASH models currently operate in numerous countries to provide insights on a variety of questions including:the effects on:macro, industry, regional, labor market, distributional and environmental variablesof changes in:taxes, public consumption, environmental policies, technologies, commodity prices, interest rates, wage-setting arrangements, infrastructure and major-project expenditures, and known levels and exploitability of mineral deposits (the Dutch disease).
