An empirical evaluation of China’s monetary policies

This paper investigates the responsiveness of the Chinese government’s monetary policies in terms of the money supply and interest rates to economic conditions and the effectiveness of these policies in achieving the goals of stimulating economic growth and controlling inflation. We analyze the responsiveness and effectiveness by estimating the Taylor rule, the McCallum rule, and a vector autoregressive model using quarterly data in the period of 1992-2009. The results show that, overall, the monetary policy variables respond to economic growth and the inflation rate, but the magnitudes of the responses are much weaker than those observed in market economies. Money supply responded actively to both the inflation rate and the real output and had certain effects on the future inflation rates and real output. The official interest rates, on the other hand, responded passively to the inflation rate and did not respond to the real output. They do not have any effect on future inflation rates and real output either.     

Nonparametric panel estimation of online auction price processes

In this study, we examine the price process of eBay online auctions. We pool sparse and unevenly spaced bidding histories of individual auctions, resulting in an unbalanced panel of bids. Since the price processes of online auctions are monotonically increasing within individual auctions and exhibit a substantial degree of heterogeneity, we propose a monotone series estimator for panel data with auction-specific slopes for a common relative price growth curve. We generalize Ramsay’s (1998, J R Stat Soc B 60(2):365–375) monotone series estimator to fit our panel model of the price process. We apply the proposed model and estimator to eBay auctions of a popular hand-held device (a Palm PDA). The results are shown to capture closely the overall pattern of observed price dynamics. In particular, the early bidding, mid-auction bidding drought, and end-auction bid sniping are well approximated by the estimated price curve.
