浅议我国最佳外汇储备规模 总被引:2,自引:0,他引:2
截止到2005年12月底,我国的外汇储备已达到8000亿美元,关于其数额是多是少的争论进行得如火如荼。本文对充足外汇储备给我国经济和社会带来的有利之处进行了理论上的分析后.又采取数学方法对我国2004年最佳的外汇储备数额进行了测算.得出了一个结论:我国的外汇储备并不多。然后,在此基础上对我国外汇储备的管理提出了几点建议。 相似文献

Current Account, Capital Formation and Terms of Trade Shocks: a Revisit of the Harberger-Laursen-Metzler Effect 总被引:1,自引:0,他引:1
This paper extends the Blanchard model of a closed-economy to a three-good (exportable, importable and non-tradable goods)
open-economy model with capital accumulation and uncertain lifetimes to study the impacts of terms of trade shocks on the
current account. The simulation results show that a model with uncertain lifetimes is more appropriate to describe a small
open economy like Taiwan at the steady-state equilibrium than a model with infinite lifetimes. We find that the Harberger-Laursen-Metzler
effect is discernible for temporary or permanent terms of trade shocks. Furthermore, the steady state is a saddle point and
the speed of convergence of capital and consumption is quite low. 相似文献

We analyze the gains from trade for a small cash-in-advance economy with endogenous labor supply and learning-by-doing in
the accumulation of human capital. Contrary to previous findings, we show that free trade is not optimal independently of
the relative amount of cash required for the purchase of each good. Furthermore, a monetary rule à la Friedman can eliminate
distortions deriving from the cash-in-advance constraint only under segmented financial markets; in any case, it cannot restore
the economic optimum. Finally, we identify government intervention policies, such as wage and export subsidies, that can be
welfare improving. 相似文献

This paper introduces sector-specific externalities in the Heckscher-Ohlin two-country dynamic general equilibrium model to show that indeterminacy of the equilibrium path in the world market can occur. Under certain conditions in terms of factor intensities, there are multiple equilibrium paths from the same initial distribution of capital in the world market, and the distribution of capital in the limit differs among equilibrium paths. One equilibrium path converges to a long-run equilibrium in which the international ranking of factor endowment ratios differs from the initial ranking; another equilibrium path maintains the initial ranking and converges to another long-run equilibrium. Since the path realized is indeterminate, so is the long-run trade pattern. Therefore, the Long-Run Heckscher-Ohlin prediction is vulnerable to the introduction of externality.

加工贸易是一种重要的贸易方式,我国正逐步成为世界加工生产的基地,我国将对加工贸易进口料件实施保税的具体做法辅以银行保证金台帐制度共同执行,实行加工贸易进口料件银行保证金台帐制度。加工贸易税款保付保函是一种海关事务担保,应属于银行的一种独立担保。但我国《民法通则》、《担保法》等立法中没有为独立担保的运作提供具体的规则,独立担保制度尤其是加工贸易税款保付保函方面的制度的完善建立势在必行。 相似文献

论提高我国本土会计师事务所竞争力的策略 总被引:1,自引:0,他引:1
国际四大所并购我国本土所的趋势已经开始显现,在这种情况下我国会计师事务所需要分析本行业的竞争现状。本文通过分析表明,我国会计师事务所既有优势、机会,也存在极大的劣势、危胁。笔者认为我国会计师事务所要采取完善公司治理、“产品”差异化、专业化、品牌化、人才、审计质量与风险控制等策略,以提高我国会计事务所的竞争力。 相似文献

The recent applied production theory literature focusing on the economic performance of firms has increasingly recognized the importance of scale effects on costs and therefore efficiency. These scale effects may include short run returns due to fixity of privately demanded inputs (i.e., capital, long run internal returns to scale, and external factors affecting costs. Since these different types of scale effects can be thought of as shifts in and movements along cost curves, the different cost effects of such factors can be identified in a framework which explicitly takes them into account in the definition ofscale.In this article we formalize such a framework, and then use it to measure short run, long run (internal) and external scale effects from fixity of private capital, nonconstant returns to scale and public infrastructure. We then use these measures to identify the impacts of these different scale factors on productivity growth. The focus on public infrastructure as an important external scale factor is motivated by the current theoretical and policy interest in this issue; we show how a structural production theory model provides a rich basis for the analysis of the cost effects of infrastructure investment. 相似文献
