Hot Money and Business Cycle Volatility： Evidence from China

This paper investigates the link between hot money and business cycle volatility in China from January 1997 to December 2009. Using the structural vector error correction model we find a considerable degree of long-run cointegration and bidirectional causality effects between hot money and business cycle volatility. The speculative shocks are found to temporarily promote China＇s economic growth, but also to exacerbate business cycle volatility. The liquidity shock stemming from hot money is shown to be the primary factor responsible for the significantly enhanced fluctuation in business cycles during the most recent global financial crisis period This could be detrimental to the smooth operation of financial markets. Therefore, informing future policies, it is critical for policy-makers to take precautions against the speculative factors.     

Transmission of China's Shocks to the BRIS Countries

This paper investigates the effects of China on the BRIS countries, namely Brazil, Russia, India and South Africa. We identify Chinese supply and demand shocks and assess their transmission to BRIS in a structural dynamic factor model framework estimated over the period 1995Q2‐2009Q4. The findings show that Chinese supply shocks are more important than its demand shocks. Supply shocks produce positive and significant output responses in all BRIS countries. And while these supply shocks have a permanent impact on the BRIS countries, the effects of demand shocks are short‐lived. Both supply and demand shocks are transmitted through trade rather than financial linkages. However, the responses of the BRIS countries are heterogeneous and therefore require country‐specific policy responses.     

Poverty Effects of the Philippines’ Tariff Reduction Program: Insights from a Computable General Equilibrium Analysis*

A computable general equilibrium micro‐simulation model is used to assess the economic and poverty impacts of tariff reduction in the Philippines. Tariff reduction induces consumers to substitute cheaper imported agricultural products for domestic goods, thereby resulting in a contraction in agricultural output. In contrast, tariff reduction reduces the domestic cost of production, benefiting the outward‐oriented and import‐dependent industrial sector. The national poverty headcount decreases marginally as lower consumer prices outweigh the nominal income reduction experienced by the majority of households. However, both the poverty gap and severity of poverty worsens, implying that the poorest of the poor become even poorer.     

Measuring Green Productivity Growth for China's Manufacturing Sectors: 1991–2000*

Over the past two decades, China has sustained rapid economic growth of 8–10 percent, part of which is attributed to the positive total factor productivity (TFP) growth. However, this extraordinary economic performance has been accompanied by severe environmental pollution and associated health damage. The conventional TFP method is biased in interpreting the progress of technology change because it does not consider non‐marketable residues, such as environmental pollution, and, hence, efficiency improvements in terms of pollution abatement technology and environmentally friendly management are ignored. This bias might direct our attention to less efficient use of environmental friendly abatement technologies or send wrong signals to policy‐makers. To address this issue, the present paper applies a modified welfare‐based green TFP approach, treating environmental damage as non‐desirable (negative) residual output. Therefore, environmental efficiency is taken into account to accurately interpret technological progress from a social welfare point of view. Based on a national time‐series input–output table, historical capital and labor input data for China and sectoral level air pollution emission data from 1991 to 2000, the empirical results suggest that with increasingly stringent environmental regulations, many pollution intensive sectors, such as electricity, primary metal and chemical industries, improved their environmental efficiency in the late 1990s. However, because of the weak environmental regulations in construction and transportation, and in sectors primarily composed of small private or township and village industrial enterprises, firms within these industries contributed to increasing environmental degradation.     

A Diagnostic on the West African Monetary Union

Deploying the classical optimum currency areas (OCA) theory and recent developments in the monetary literature, this paper evaluates the appropriateness of West African Monetary Union (WAEMU) as a monetary zone. Nine macroeconomic dimensions are investigated under which the first four items are quantified against a reference economy, namely the United States, the eurozone or China, while the rest are measured in absolute terms for time periods before and after the 2008‐2009 global financial crisis. Results could signify relative dominance of the three world's largest economies to the West African region. In addition to inherent asymmetries across the union, findings suggest the emerging Chinese yuan as an alternative to the euro as the monetary anchor.
