Several recent papers (e.g., Newey et al., 2005; Newey and Smith, 2004; Anatolyev, 2005) derive general expressions for the second-order bias of the GMM estimator and its first-order equivalents such as the EL estimator. Except for some simulation evidence, it is unknown how these compare to the...

Between June 1998 and March 2006, the price index of apartment housing in Seoul, Republic of Korea, more than doubled, while fundamentals such as gross domestic product, wage, and population increased by less than 35%. This study examines the role of a rational speculative bubble in this price...

The paper investigates the efficiency of procurement for medical devices. Differentiation of products in this market, due to doctors' preferences for specific technologies, might reduce the number of suppliers and the potential positive impact of auctions relative to negotiations. Using a large...

This paper studies the sensitivity of cash flows generated by Taiwanese firms to changes in a trade-weighted index, as well as against the currencies of Taiwan's major trading partners. A traditional methodology, the capital market approach, typically found low or negligible levels of exposure...

Consumer value may be defined as a tool to measure the prolonged satisfaction and the on-going propensity to buy products and services. Though there are many issues floating in current debates about consumer value, it may be argued that the importance of consumer value in terms of the level of...

This work analyses the evolution of real public expenditures of local and regional administrations (LRA), in Portugsl, in the period after the Second World War. It also aims to estimate the elasticities associated to determinants, which explain the found growth. As most relevant results, it is...

The classical binary classification problem is investigated when it is known in advance that the posterior probability function (or regression function) belongs to some class of functions. We introduce and analyze a method which effectively exploits this knowledge. The method is based on...

We present a simple randomized procedure for the prediction of a binary sequence. The algorithm uses ideas from recent developments of the theory of the prediction of individual sequences. We show that if the sequence is a realization of a stationary and ergodic random process then the average...

In this study, we employ an innovative new methodology inspired from the approach of Hwang and Salmon (2004) and based on the cross sectional dispersion of trading volume to examine the herding behavior on Toronto stock exchange. Our findings show that the herd phenomenon consists of three...

We present some new asymptotic results for functionals of higher order differences of Brownian semi-stationary processes. In an earlier work [4] we have derived a similar asymptotic theory for first order differences. However, the central limit theorems were valid only for certain values of the...
