Around the mid-1980s, Indonesia's protectionist regime supported an industrial structure in which industries were mainly oriented towards producing for the domestic market. Since then, trade policies have shifted to a more outward-looking strategy, stimulating the growth and diversification of non-oil manufactured exports. This paper attempts to quantify the nominal and effective rates of protection resulting from trade policies at the end of the 1980s. After an introduction in which the 1989 trade policies are discussed, estimates of nominal and effective rates of protection are presented. It is shown that though the level of protection has declined since 1987, it still varies widely across economic sectors. Furthermore, despite the more open trade strategy, the paper's findings show that the trade regime remains biased against exports. Finally, by examining some trade policy issues, the paper presents further ways of rationalising the structure of protection in Indonesia's industrial sector.  相似文献

This paper considers the proposals put forward by the EC at the GATT Uruguay Round in December 1990. The EC's objective of rebalancing the Common Agricultural Policy in the context of a partial liberalisation of agricultural support on the world cereals market is assessed, as is the choice of base year from which liberalisation would have been initiated. The US's proposal for more significant reduction in agricultural support is also considered. The results show that the EC would not necessarily have benefited from rebalancing, since the effects would have depended on the choice of base period. For example, with 1986 (1988) as the base year, net welfare changes would have been 20 (50) percent higher (lower) with rebalancing, relative to the case without. Not surprisingly, the more substantial liberalisation proposed by the US would have resulted in greater net welfare gains even if rebalancing was conceded by the US.  相似文献

Among the economies with a Currency Board System (CBS), Hong Kong (HK) is probably the one with the largest and most developed financial sector, as well as the highest capital mobility. Hence, studying HK’s CBS is not only crucial to HK, but also important for the understanding of the modern CBS. This paper outlines the major monetary reforms in HK since the late 1980s. The impacts of these reforms and the 1997–1998 Asian Financial Crisis are then examined empirically. We focus on the differentials between the US and HK interbank interest rates. We assume the conditional-mean equation follows an autoregressive process and the conditional-variance equation follows a generalized autoregressive conditional heteroscedasticity process. This model captures the time-varying level and volatility of the differential. In light of the empirical results we provide an assessment of the reforms in HK.  相似文献

Cross entropy is used to estimate the Almost Ideal Demand System for consumption in Greece. The entropy estimates are found to improve upon the SUR estimates. It is recommended that practitioners consider employing entropy based procedures in systems where the data set is small, where there are a large number of parameters, or where the data are deficient.  相似文献

Optimal investment rules are developed for a producer agency investing in domestic-market generic advertising, export market promotion, and cost-of-production-reducing research. These rules are derived assuming either maximization of producers' surplus or social surplus. The form of the optimality rules differs according to which objective is pursued. Fixed producer agency budgets are also allowed by incorporating a constraint limiting total expenditure on the three activities. Addition of such a constraint substantially alters the structure of the optimal investment rules. Differences in these rules highlight the importance of accounting for the financing mechanism when modeling optimal checkoff fund investment decisions. Optimality rules are simulated using data for the Canadian beef sector. Results suggest historic underinvestment in domestic-market generic advertising but overinvestment in export market promotion. Sensitivity of simulation results underscores the difficulty in assessing optimality of historic producer investment in cost-of-production-reducing research.  相似文献

Summary In The Netherlands public debt management is in the hands of the budgetary policy-maker, whose recourse to the capital market can exceed or fall short of the total borrowing requirement in order to absorb or create liquidity. The conduct of that policy since the early 1960's is analyzed in this paper, emphasizing the importance of medium-term control over the public finances as a prerequisite for the ability of debt management to make a flexible contribution to monetary policy. During the 1960's this condition was satisfied and debt management followed a stable countercyclical pattern which, however, was abandoned after the early 1970's as the public finances swung into substantial disequilibrium.The author thanks J. Boughton, L. Bovenberg, D. Hendry, P. Masson, J. Muellbauer, and the referees for comments on earlier versions. However, the views expressed are his alone and do not necessarily represent those of the International Monetary Fund.  相似文献

Policies to promote real-time metering (RTM) require more than showing benefits from more timely responses to variations in cost. They require positive externalities to imply that too few meters would be installed through private transactions. RTM presents no systematic externalities when utilities must serve peak period users, and may present negative externalities under some conditions. Positive externalities are likely when electricity is rationed through blackouts. RTM may or may not increase welfare when peak period wholesale markets are not competitive; a prohibition on RTM might be appropriate in such situations even if metering itself were costless.  相似文献
