Monetary policy of a small open economy in the world production chain

In the world production chain there is a small economy that outsources production to its upstream, sells intermediate goods to its downstream and consumes imported final goods. It is shown that in responding to shocks from demand for intermediate goods, from the wage rate in the upstream and from the currency exchange rate between the upstream and downstream countries, the monetary policy of the small country is insignificant in the sense that any attempt of changing its monetary stance to raise national welfare will be offset by the movements of exchange rates.     

Predicting issuer credit ratings using a semiparametric method

This paper proposes a prediction method based on an ordered semiparametric probit model for credit risk forecast. The proposed prediction model is constructed by replacing the linear regression function in the usual ordered probit model with a semiparametric function, thus it allows for more flexible choice of regression function. The unknown parameters in the proposed prediction model are estimated by maximizing a local (weighted) log-likelihood function, and the resulting estimators are analyzed through their asymptotic biases and variances. A real data example for predicting issuer credit ratings is used to illustrate the proposed prediction method. The empirical result confirms that the new model compares favorably with the usual ordered probit model.     

Does intellectual monopoly stimulate or stifle innovation?

This study develops an R&D-based growth model with vertical and horizontal innovation to shed some light on the current debate on whether patent protection stimulates or stifles innovation. We analyze the effects of patent protection in the form of blocking patents. We show that patent protection changes the direction of innovation by having asymmetric effects on vertical innovation (i.e., quality improvement) and horizontal innovation (i.e., variety expansion). Calibrating the model and simulating transition dynamics, we find that strengthening the effect of blocking patents stifles vertical innovation and decreases economic growth but increases social welfare due to an increase in horizontal innovation. In light of this finding, we argue that in order to properly analyze the growth and welfare implications of patents, it is important to consider their often neglected compositional effects on vertical and horizontal innovation.

Economic development and carbon dioxide emissions in China: Provincial panel data analysis

This paper investigates the driving forces, emission trends and reduction potential of China's carbon dioxide (CO₂) emissions based on a provincial panel data set covering the years 1995 to 2009. A series of static and dynamic panel data models are estimated, and then an optimal forecasting model selected by out-of-sample criteria is used to forecast the emission trend and reduction potential up to 2020. The estimation results show that economic development, technology progress and industry structure are the most important factors affecting China's CO₂ emissions, while the impacts of energy consumption structure, trade openness and urbanization level are negligible. The inverted U-shaped relationship between per capita CO₂ emissions and economic development level is not strongly supported by the estimation results. The impact of capital adjustment speed is significant. Scenario simulations further show that per capita and aggregate CO₂ emissions of China will increase continuously up to 2020 under any of the three scenarios developed in this study, but the reduction potential is large.     

Futures prices and inflation information

This study examines the timing and speed with which inflation futures prices absorb inflation information. Results of the study show that inflation futures prices already reflect the expected inflation. Moreover, 71% of unexpected inflation has been reflected in futures prices about 25 business days prior to the Consumer Price Index (CPI) announcement, which usually coincides with the end of the CPI measurement period. Reaction to the remaining 29% occurs on and shortly after the CPI announcement date, especially on day 0 and day 2. The inflation risk premium that investors are willing to pay to avoid uncertain inflation is estimated to be 1.41% per annum.     

The Chinese interbank repo market: An analysis of term premiums

Because of the lack of short‐term government bonds, the interbank repo market in China has been providing the best information about market‐driven short‐term interest rates since its inception. This article examines the behavior of the repo rates of various terms and their term premiums. The work in this article supplements the study by F. Longstaff (2000), which reports supportive evidence for the pure expectations hypothesis over the short range of the term structure with the use of repo data from the United States. It is found that the pure expectations hypothesis is statistically rejected, although the term premiums are economically small. It is shown that the short‐term repo rate, repo rate volatility, repo market liquidity, and repo rate spreads are all important in determining the term premiums. © 2006 Wiley Periodicals, Inc.
