日元汇率与亚洲经济 日元贬值将使亚洲金融危机死灰复燃

日元贬值的根本原因在于世界三大贸易区之间的竞争日趋激烈。     

日元:末路狂奔

近来,日元急剧贬值令整个东亚不安. 从2000年11月以来,日元走势呈现罕见的单边下挫态势.2001年12月27日,东京外汇市场日元兑美元的汇率跌至132.04,为1998年10月初以来的最低点.仅约一年,日元就异乎寻常地贬值了15.8%,进入2001年12月以来,日元跌势更为汹涌,月内跌幅超过了6.5%!     

日元贬值中国船舶工业遇“双刃剑”

中国人民银行授权中国外汇交易中心公布,2013年6月24日银行间外汇市场人民币汇率中间价为：100H元兑人民币6．224元．日元对人民币的贬值仍在继续。总体上看．日元贬值对中国一般商品的进出口贸易产生的负面影响较小．而对包括船舶产品在内的机电产品出口产生的阶段性影响较大。     

Devaluation without common knowledge

In an economy with a fixed exchange rate regime that suffers a random adverse shock, we study the strategies of imperfectly and sequentially informed speculators that may trigger an endogenous devaluation before it occurs exogenously. The game played by the speculators has a unique symmetric Nash equilibrium which is a strongly rational expectation equilibrium in the set of all strategies with delay. Uncertainty about the extent to which the Central Bank is ready to defend the peg extends the ex ante mean delay between the exogenous shock and the devaluation. We determine endogenously the rate of devaluation.     

Determinants of Japanese Yen interest rate swap spreads: Evidence from a smooth transition vector autoregressive model

This study investigates the determinants of variations in the yield spreads between Japanese yen interest rate swaps and Japan government bonds for a period from 1997 to 2005. A smooth transition vector autoregressive (STVAR) model and generalized impulse response functions are used to analyze the impact of various economic shocks on swap spreads. The volatility based on a GARCH (generalized autoregressive conditional heteroskedasticity) model of the government bond rate is identified as the transition variable that controls the smooth transition from a high volatility regime to a low volatility regime. The break point of the regime shift occurs around the end of the Japanese banking crisis. The impact of economic shocks on swap spreads varies across the maturity of swap spreads as well as regimes. Overall, swap spreads are more responsive to the economic shocks in the high volatility regime. Moreover, a volatility shock has profound effects on shorter maturity spreads, whereas the term structure shock plays an important role in impacting longer maturity spreads. Results of this study also show noticeable differences between the nonlinear and linear impulse response functions. © 2008 Wiley Periodicals, Inc. Jrl Fut Mark 28:82–107, 2008     

Devaluation: Levels versus rates

In a context of infinitely-lived families à la Sidrauski, where consumers are lump-sum compensated for the inflation tax, and there is no capital mobility, it is shown that a devaluation improves while an increase in the rate of devaluation deteriorates the balance of payments.     

资产组减值的会计核算

《企业会计准则第8号——资产减值》充分借鉴国际会计准则做法,首次引入了"资产组"、"总部资产"与"资产组组合"等概念,要求对于不能独立产生现金流入的资产,应当按其所归属的资产组为基础进行减值测试,计算确认减值损失。     

Devaluation,Innovation, and Prices

We investigate the effects of exchange rate changes on innovation by a multinational corporation. The firm enjoys a monopoly in the home market but engages in Cournot competition with a domestic firm in the foreign market. Changes in currency values affect the multinational firm’s profits in domestic currency units, and thus influence the optimal level of process innovation as well as output and prices in the two markets. We find that a devaluation of the home currency will lead the home firm to increase its output in both the home and foreign markets, and increase its spending on R&D. We also find that currency devaluation in the home market leads to lower prices in both markets.     

Devaluation and its consequences in developing countries

To analyze the role of the trade and payments regime in economic development the National Bureau of Economic Research undertook a major research project on this issue. In this article a brief report on some of the findings pertaining to the effect of exchange rates, i. e. devaluation under exchange control is provided.     

Devaluation - Defeat or Golden Opportunity?

This paper considers whether the recent sterling devaluation represents a defeat for government policy or a golden opportunity for industrial recovery. It argues that devaluation offers a window of opportunity for higher growth and investment, but that this will disappear after two or three years with higher inflation. The risk is that this may distract firms from the necessity of competing on product and process innovation and marketing. The damage to the credibility of government policy has also been profound.
