Dynamic Analysis of the Exchange Rate Regime: Policy Implications for Emerging Countries in East Asia 下载免费PDF全文
This paper discusses exchange rate policies in East Asia. In particular, we explore whether actual policies that have been implemented by East Asian countries after the Asian Financial Crisis follow or deviate from theoretically “desirable” policies over the medium and long terms. On theoretical analysis, we show the relative superiority of a basket‐peg regime with the basket weight rule when compared with a floating regime implementing the interest rate rule or money supply rule. For countries that currently adopt a fixed exchange rate regime, they would be better off shifting toward either a basket‐peg or a floating regime over the medium term. A shift to a basket peg is more preferred when compared with a shift to a floating regime when the exchange rate fluctuations are large. 相似文献

The Hoggard–Whalley–Wilmott equation is introduced to model portfolios of European type options incorporating transaction
costs. The model gives rise to a nonlinear parabolic partial differential equation (PDE), whose nonlinearity reflects the
presence of transaction costs. We show analytically the existence of solutions which are not necessarily convex nor concave.
Numerical treatments are also given, which are devised to effectively handle an infinite domain and unbounded solutions.

We present empirical evidence using daily data for stock prices for 17 real estate companies traded in the Sao Paulo, Brazil stock exchange, from August 26, 2006 to March 31, 2010. We use the U.S. house price bubble, financial crisis and risk measures to instrument for momentums and reversals in the domestic real estate sector. We find evidence of conditional premium persistence and conditional volatility persistence in the market. We find that the conditional risk-return relationship in the sector is consistent with the prospect theory of risk attitudes in this period. Certain companies seem to be operating on a perceived potential industry return above the target, while most others are below the target, and the whole sector is below target on average. 相似文献

Japan has suffered from sluggish economic growth and recession since the early 1990s. In this paper, we analyze the causes of the prolonged slowdown of the Japanese economy (the lost decade). Economics Nobel laureate Paul Krugman has argued that Japan's lost decade is an example of a liquidity trap. However, our empirical analysis shows that stagnation of the Japanese economy comes from its vertical IS curve rather than a horizontal LM curve, so the Japanese economy has been facing structural problems rather than a temporary downturn. The vertical IS curve is caused by an insensitivity of investment to a lower interest rate partly because of the decline of sales due to the aging population and firms not wanting to invest. The structural problems come from the aging demographic, which is often neglected by scholars and policy‐makers, and also from the allocation of transfers from the central government to local governments, and the unwillingness of Japanese banks to lend money to startup businesses and small and medium enterprises (SMEs), mainly because of Basel capital requirements. Many countries, like China, are expected to face similar issues, particularly given the aging population. The present paper will address why the Japanese economy has been trapped in a prolonged slowdown and provide some remedies for revitalizing the economy. 相似文献

We are concerned with a model for asset prices introduced by Koichiro Takaoka, which extends the well known Black-Scholes model. For the pricing of contingent claims, partial differential equation (PDE) is derived in a special case under the typical delta hedging strategy. We present an exact pricing formula by way of solving the equation.

In this study, we investigate ordering patterns of different types of market participants in Tokyo Stock Exchange (TSE) by examining order records of the listed stocks. Firstly, we categorize the virtual servers in the trading system of TSE, each of which is linked to a single trading participant, by the ratio of cancellation and execution in the order placement as well as the number of executions at the opening of the afternoon session. Then, we analyze ordering patterns of the servers in the categories in short intervals for the top 10 highest trading volume stocks. By classifying the intervals into four cases by returns, we observe how different types of market participants submit or execute orders in the market situations. Moreover, we investigate the shares of the executed volumes for the different types of servers in the swings and roundabouts of the Nikkei 225 index, which were observed in September in 2015. The main findings of this study are as follows: Server type A, which supposedly includes non-market making proprietary traders with high-speed algorithmic strategies, executes and places orders along with the direction of the market. The shares of the execution and order volumes along with the market direction increase when the stock price moves sharply. Server type B, which presumably includes servers employing a market making strategy with high cancellation and low execution ratio, shifts its market making price ranges in the rapid price movements. We observe that passive servers in Server type B have a large share and buy at low levels in the price falls. Also, Server type B, as well as Server type A, makes profit in the price falling days and particularly, the aggressive servers in the server type make most of the profit. Server type C, which is assumed to include servers receiving orders from small investors, constantly has a large share of execution and order volume. 相似文献

We deal with the solvability and a weak formulation of nonlinear partial differential equations of Black-Scholes type for the pricing of options in the presence of transaction costs. Examples include the Hoggard–Whalley–Wilmott equation, which is introduced to model portfolios of European type options with transaction costs based on the idea of Leland. The cost structure gives rise to nonlinear terms. We show the existence and the uniqueness of solutions both in the classical and the weak sense, where the notion of weak solutions is introduced. 相似文献
