The Great Collapse in Value Added Trade

This paper studies the great collapse in value added trade using a structural decomposition analysis. We show that changes in vertical specialization accounted for more than 40% of the great trade collapse. Second, we find that the drop in the overall level of demand accounted for roughly a quarter of the decline in value added exports while just under one third was due to compositional changes in final demand. Finally, we demonstrate that the dichotomy between services and manufacturing sectors observed in gross exports during the great trade collapse is not apparent in value added trade data.     

Optimum government credibility in an open-economy fiscal expansion

A real open-economy model is constructed in which the government's commitment to a future fiscal expansion is not credible. Government credibility (measured by the growth rate of the probability that the expansion will occur) becomes a parameter of the system and appears directly in the eigenvalues. Simulations are performed demonstrating the effect of credibility on GNP, the exchange rate, and other variables. Lastly, the optimum credibility is determined which minimizes a loss function associated with deviations from full employment.     

Inflation in the USA,UK and Australia:Some Comparisons*

USA, UK and Australian wage inflation experiences during the post-World-War-II period are examined principally within the framework of the long-run Phillips curve model. Attention is drawn to the sensitivity of wage rate changes to retail price level changes and to the possibility of a temporal change in this relationship. The analyses of these countries are compared so as to highlight similarities and differences.     

Nontraded Goods and Real Exchange Rates in a Multi‐Good Ricardian Model

The two‐country Ricardian trade model with discrete goods and uniform transport costs for tradable goods is applied to the decomposition of the real exchange rate into traded and nontraded components. The real exchange rate is driven almost entirely by changes in the productivity differentials in nontraded goods and also explains the Balassa–Samuelson effect of a lower cost of living in poor countries, but extraordinary transport costs for some nontraded goods are necessary to easily explain the Balassa–Samuelson effect.     

ICP 2005 Construction Prices: Are They Underestimated in Developing Countries?

Construction prices are lower in developing countries in ICP 2005, which has raised these countries' capital/output ratio in Penn World Tables 7 and 8 and affected growth analyses. We estimate the Colombia/U.S. price ratio for office and apartment buildings in 2005 as a test of the validity of the ICP 2005 methodology for estimating these prices. Our estimate of the Colombia/U.S. price ratio is almost twice the ICP 2005 estimate. We confirm the validity of our results by estimating the cost of constructing office and apartment buildings using 2005 prices for construction materials, equipment, and labor in both countries.     

Guiding it through

Some relatively little known Members of Congress and an even less visible group of aides are playing important behind-the-scenes roles in the health care reform debate.
