Emerging markets, evolving institutions, and the new opportunities for growth in China's rural economy

In this essay, our goal is to assess the state of China's rural economy and examine whether rural China is capable of participating in the sequence of economic events that will lead to modernization. We examine how agricultural productivity has changed, the nature of the shift of labor moving from rural to urban areas, how commodity markets have evolved, and how the rural industrial sector is adjusting the recent reforms. According to our own work and that of others, we show how the rural economy is beginning to be fundamentally transformed and is contributing to China's modernization.

The Political Economy of Exchange Rate Regimes: Evidence from Hong Kong and Taiwan

This paper investigates whether the macroeconomic performance of a small- open economy depends on the choice of exchange rate regimes. Hong Kong and Taiwan - two economies with many similar macroeconomic characteristics, but different in their choices of exchange rate regimes - provide a good setting to study the relation between the choice of exchange rate regime and macro-economic performance. We examine the basic facts of growth and inflation and the coefficients' stability of their vector autoregression (VAR), as well as cyclical characters of other aggregate variables in Hong Kong and Taiwan. Our empiric finding indicates that macroeconomic performance is not systematically related to exchange rate regimes.
