This paper examines whether China’s switch back and forth from fixed to floating exchange rates in 2005 and 2008 changed the contribution to stock price discovery by foreign and domestic investors. During that time, mainland investors could only trade the RMB-denominated A-shares in the domestic Shanghai and Shenzhen markets, while the dual-listed HKD-denominated H-shares were available only to overseas investors. Using intraday data on overlapping trading hours, we find that the switch from a fixed rate to managed floating in July 2005 increased the H-shares’ contribution to price discovery; while the exchange rate regime reversal in July 2008 allowed the domestic stocks to regain their dominance in information shares. These results imply that, in a market subject to restrictions on capital flows, a flexible exchange rate regime increases the propensity of investors to trade foreign-issued stocks to speculate on the RMB exchange rate, which raises overseas investors’ contribution to price discovery.

In order to examine the new RMB exchange rate regime rigorously, we employ the STARTZ model to investigate the behavior of RMB NEER from June 1, 2006 to May 30, 2008, We find that a managed float with a target central parity and without an explicit band best describes the daily movement of the exchange rate between RMB and a basket of currencies. We also find some peculiar attributes of the RMB NEER such as small conditional variance and stronger effects of government interventions in foreign exchange market.

A model of the domestic financial intermediation of foreign capital inflows based on agency costs is developed for studying financial crises in emerging markets. In equilibrium, the banking system becomes progressively more fragile under imperfect prudential regulation and public sector loan guarantees until a crisis occurs with a sudden reversal of capital flows. The crisis evolves endogenously as the banking system becomes increasingly vulnerable through the renegotiation of loans after idiosyncratic firm-specific revenue shocks. The model generates dynamic relationships between foreign capital inflows, domestic investment, corporate debt and equity values in an endogenous growth model The model's assumptions and implications for the behavior of the economy before and after crisis are compared to the experience of five East Asian economies. The case studies compare three that suffered a crisis or near-crisis, Thailand and Malaysia, to two that did not, Taiwan Province of China and Singapore, and lend support to the model.

This paper sheds new light on the external and domestic dimension of China's exchange rate policy. It presents an open economy model to analyze both dimensions of macroeconomic adjustment in China under both flexible and fixed exchange rate regimes. The model-based results indicate that persistent current account surpluses in China cannot be rationalized, under general circumstances, by the occurrence of permanent technology or labor supply shocks. As a result, the understanding of the macroeconomic adjustment process in China requires to mimic the effects of potential inefficiencies, which induce the subdued response of domestic absorption to permanent income shocks causing thereby the observed positive unconditional correlation of trade balance and output. The paper argues that these inefficiencies can be potentially seen as a by-product of the fixed exchange rate regime, and can be approximated by a stochastic tax on domestic consumption or time varying transaction cost technology related to money holdings. Our results indicate that a fixed exchange regime with financial market distortions, as defined above, might induce negative effects on GDP growth in the medium-term compared to a more flexible exchange rate regime.

In recent times, the prices of internationally-traded commodities have reached record highs and are expected to continue growing in the foreseeable future. This phenomenon is partially driven by strong demand from a small number of emerging economies, such as China and India. This paper places the recent commodity price boom in historical context, drawing on an investigation of the long-term time-series properties, and presents unique features for 33 individual commodity prices. Using a new methodology for examining cross-sectional variation of commodity returns and its components, we find strong evidence that the prices of world primary commodities are extremely volatile. In addition, prices are roughly 30 percent more volatile under floating than under fixed exchange rate regimes. Finally, using the capital asset pricing model as a loose framework, we find that global macroeconomic risk components have become relatively more important in explaining commodity price volatility.

The supposed undervaluation of the renminbi has been the subject of intensive academic research over the past few years. Using equilibrium exchange rate models (Purchasing Power Parity, BEER and FEER), many authors have concluded that the renminbi is undervalued by 15 to 30% against the dollar. This article shows that the common view is not that obvious. The models used in the estimation (BEER or FEER) assume that the economy is at full-employment, a strong hypothesis for developing economies such as China, whose unemployed amount to 150 million people. On the contrary, we show that China is facing massive unemployment and if investment depends on expected potential demand (from domestic consumption and foreign demand), then an undervalued exchange rate (by traditional standards) is suited for its policy objectives. Therefore the exchange rate can be analyzed as a policy tool used by the Chinese authorities to pursue their objectives. The exchange rate can be undervalued by traditional standards and in equilibrium compared to the government's policy objectives. This article shows that equilibrium exchange rate theories are not suited for developing countries and therefore the concept of equilibrium exchange rate is highly questionable. The final section analyzes the adoption of a managed float regime by the Popular Bank of China and discusses the delicate issue of the best exchange rate regime for China.

One argument for floating the Chinese renminbi (RMB) is to insulate China's monetary policy from the US effect. However, we note that both theoretical considerations and empirical results do not offer a definite answer on the link between exchange rate arrangement and policy dependence. We examine the empirical relevance of the argument by analyzing the interactions between the Chinese and US interest rates. Our empirical results, which appear robust to various assumptions of data persistence, suggest that the US effect on the Chinese interest rate is quite weak. Apparently, even with its de facto peg to the US dollar, China has alternative measures to retain its policy independence and de-link its interest rates from the US rate. In other words, the argument for a flexible RMB to insulate China's monetary policy from the US effect is not substantiated by the observed interest rate interactions.

This paper proposes a path-dependent approach for estimating maximum appreciations of the renminbi expected by the market based on first-passage-time distributions. Using market data of the renminbi spot exchange rates, non-deliverable forward rates and currency option prices from 21 July 2005 (the reform of the exchange rate regime) to 28 February 2008 for model parameters, the maximum appreciations of the renminbi estimated under the proposed approach show that the market expected another large movement of the exchange rate during the 14 months after the reform. Subsequently, the few occasions of appreciations beyond the expected maximums coincided with the trade-related issues and speculations of greater momentum of appreciation allowed by the authorities. The PBoC's measures were however largely incorporated into the derivatives' prices. The proposed approach can be used to gauge the range of appreciations of the renminbi anticipated in the market and to identify any exchange rate movements beyond market expectations.

On 21 July 2005 China adopted an undisclosed basket exchange rate regime. We formally assess and envisage the gradual evolution of the renminbi over time. We utilize nonlinear dependencies in the renminbi exchange rate and describe the smooth transition of the renminbi/U.S. dollar (RMB/USD) exchange rate using the family of time-varying autoregressive (TV-AR) models. The results indicate that the forward-looking nonlinear model adequately depicts the gradual reform process underlying the new RMB exchange rate regime.
