The debate on trade and growth increasingly focuses on the composition of exports. Exports of more "sophisticated" products appear to be positively correlated with growth, and upgrading the quality of exports is high on the policy agenda of many countries. This study presents evidence suggesting that attracting inflows of FDI offers potential for upgrading a country's export basket. The empirical analysis relates unit values of exports measured at the 4-digit SITC level to data on sectors treated by investment promotion agencies as priority in their efforts to attract FDI. The sample covers 116 countries over the period 1984-2000. The findings are consistent with a positive effect of FDI on unit values of exports in developing countries. However, such a relationship is less evident in developed countries. These results suggest that FDI can help bridge gaps in production and marketing techniques between developing and high income economies.

We estimate fiscal reaction functions for non-hydrocarbon tax and public spending shares of national income and for debt management strategies adopted by Norway and compare these with rules that would prevail under the permanent income hypothesis and bird-in-hand rule. We conclude that the fiscal reaction functions adopted by Norway have to some extent been forward-looking when it comes to the rising pension bill, but backward-looking when it comes to hydrocarbon revenues. Still, our results suggest that the imminent costs of a rapidly graying population are not sufficiently taken into account in the current fiscal rules, since Norway is on a trajectory of turning a current net asset-GDP-ratio close to one into a net debt-GDP-ratio of two in 2060. Something needs to give in the holy trinity: either the rules of the Stabilization fund have to be tightened, or civil servant salaries, benefits and pensions will no longer have to be fully indexed to market wages, or the retirement age has to be increased.

AbstractThe analysis of the effect of tariffs for labour productivity faces the challenge of tariff policy endogeneity. Tariff policy is designed to promote economic development and the industrial sector tariff structure may reflect characteristics of the industries protected. We seek to identify the effect of tariffs by taking advantage of multilateral tariff liberalization using reductions in industrial sector tariffs in other world regions as instruments for sectoral tariff reductions in South Africa. The data cover 28 manufacturing sectors over the period 1988–2003. We find that tariff reductions have stimulated labour productivity when instrumented by multilateral tariffs. The ordinary least‐squares estimates show downward bias and this confirms the endogeneity of tariffs. Investigation of channels of effects shows some support for the importance of competitive pressure and technology spillover from trade liberalization.

The analysis of the effect of tariffs for labor productivity faces the challenge of tariff policy endogeneity. Tariff policy is designed to promote economic development and the industrial sector tariff structure may reflect characteristics of the industries protected.

The data cover 28 manufacturing sectors over the period 1988-2003. We find that tariff reductions have stimulated labor productivity when instrumented by multilateral tariffs. The OLS estimates show downward bias and supports the understanding that the government has given priority to tariff reductions in sectors with slow productivity growth.

The barrier model of productivity growth suggests that individual country productivity is related to the world technology frontier disturbed by national barriers. We offer a country study of the barrier model exploiting the dramatic changes in the linkages to the world economy in South Africa. The productivity growth in the manufacturing sector panel for 1970-2003 covers a period of political and economic turbulence and international sanctions. The econometric analysis uses tariffs as measure of barrier and fixed effects estimation to concentrate inference to time series properties. The model shows how productivity growth can be understood as a combination of world frontier growth and the tariff barrier to international spillovers. The estimates establish a long run relationship where domestic productivity follows the world frontier and with change of the barrier affecting transitional growth.

Abstract
We estimate the effect of giant oil and gas discoveries on bilateral real exchange rates. A giant discovery with the value of 10% of a country's GDP appreciates the real exchange rate by 1.5% within ten years following the discovery. The appreciation starts before production begins and the non-traded component of the real exchange rate drives the appreciation. Labour reallocates from the traded goods sector to the non-traded goods sector, leading to changes in labour productivity. These findings provide direct evidence on the channels central to the theories of the Dutch disease and the Balassa–Samuelson effect.

Official forecasts for oil revenues and the burden of pensioners are used to estimate forward-looking fiscal policy rules for Norway and compared with permanent-income and bird-in-hand rules. The results suggest that fiscal reactions have been partial forward-looking with respect to the rising pension bill, but backward-looking with respect to oil and gas revenues. Solvency of the government finances might be an issue with the fiscal rules estimated from historical data. Simulation suggests that declining oil and gas revenue and the costs of a rapidly graying population will substantially deteriorate the net government asset position by 2060 unless fiscal policy becomes more prudent or current pension and fiscal reforms are successful.
