A unified framework of trade in value added : physical, monetary, exchange rates, and GHG emissions

Koopman et al. (2014) developed a method to consistently decompose gross exports in value-added terms that accommodate infinite repercussions of international and inter-sector transactions. This provides a better understanding of trade in value added in global value chains than does the conventional gross exports method, which is affected by double-counting problems. However, the new framework is based on monetary input--output (IO) tables and cannot distinguish prices from quantities; thus, it is unable to consider financial adjustments through the exchange market. In this paper, we propose a framework based on a physical IO system, characterized by its linear programming equivalent that can clarify the various complexities relevant to the existing indicators and is proved to be consistent with Koopman's results when the physical decompositions are evaluated in monetary terms. While international monetary tables are typically described in current U.S. dollars, the physical framework can elucidate the impact of price adjustments through the exchange market. An iterative procedure to calculate the exchange rates is proposed, and we also show that the physical framework is also convenient for considering indicators associated with greenhouse gas (GHG) emissions.

Measuring Fiscal Decentralization in the Philippines

This paper focuses on the fiscal decentralization in the Philippines after the 1991 Local Government Code. It first examines the intergovernmental fiscal relationship between central and local governments by using fiscal decentralization indicators, and then investigates its impact on local finance. After fiscal decentralization, the local expenditure responsibility is expanded while the local fiscal capacity is not strengthened in the Philippines. Local governments consequently comes to depend heavily on fiscal transfers from the central government, internal revenue allotments (IRAs), which has a substantial influence on local finance. The heavy dependence on IRAs makes local finance unpredictable and unstable. The distribution of IRAs also affects the horizontal balance between provincial governments.
