MARKET STRUCTURE AND TRADING VOLUME

Historically, trading volume reported for NASDAQ stocks has been overstated vis‐à‐vis New York Stock Exchange (NYSE) stocks, both because of the dealer's participation in trades as a market maker and because of interdealer trading. Beginning in 1997, the Securities and Exchange Commission changed order‐handling rules and trade‐reporting rules, which may have reduced or eliminated the overstatement of NASDAQ trading. We examine trading volumes of firms changing from NASDAQ to the NYSE since 1997 and document that reported trading volume for NASDAQ stocks continues to be overstated. Moreover, the degree of overstatement is much larger for firms with high trading volume.     

The cross‐Euler equation approach to intertemporal substitution in import demand

This paper addresses the empirical dilemma in identifying and estimating the parameters governing the intertemporal elasticity of substitution (IES) for import demand. We propose a new concept, the cross‐Euler equation, for overcoming this empirical dilemma. IES parameters are estimated by exploiting the cointegrating restriction implied by the cross‐Euler equation. Further, by comparing the IES estimates from the cross‐Euler equation to those from the standard Euler equation, we test the hypothesis whether import demand is affected by nuisance factors. Using the US data, we found imported goods consumption to be robust against nuisance factors, but not for domestic goods. Copyright © 2005 John Wiley & Sons, Ltd.     

Factors affecting consumer acceptance of chilled ready meals on the island of Ireland

The chilled ready meal market on the island of Ireland is relatively young but is growing rapidly. This paper focused on a consumer questionnaire (n = 702), designed to examine consumer attitudes to and consumption of chilled ready meals, in both the north and south of Ireland. This formed part of a larger study, with the questionnaire findings contributing to an in‐depth sensory study on a selected range of chilled ready meals. For a significant number of Irish consumers, consumption of these products is higher than on the UK mainland. For others, the products are purchased as a convenient alternative or a weekly treat. Respondents in urban locations were significantly more likely to consume chilled ready meals, as were men and younger, single respondents. Irish consumers are becoming more accustomed to ethnic cuisine although traditional meals remain popular. There is a clear need for developers to continue to enhance the sensory quality of these products, particularly as the primary barrier to consumption was a preference for home cooked food. However, they must also strive to maintain consumer interest in the sector, fulfil the desire for convenience and satisfy a more discerning palate.     

Effectiveness of Mediation Strategies in Collective Bargaining

Effectiveness of mediation strategies is analyzed in two different types of collective labor conflicts: rights conflicts and conflicts of interests. The sample consists of 106 professional labor mediators who completed a questionnaire about the strategies they used and the outcomes they achieved in their most recent mediation intervention. Results from regression analysis indicate that while the use of substantive and contextual strategies is positively related to effectiveness in both types of conflict, the use of reflexive strategies is negatively related to effectiveness, particularly in rights conflicts.     

A random coefficient autoregressive Markov regime switching model for dynamic futures hedging

The random coefficient autoregressive Markov regime switching model (RCARRS) for estimating optimal hedge ratios, which generalizes the random coefficient autoregressive (RCAR) and Markov regime switching (MRS) models, is introduced. RCARRS, RCAR, MRS, BEKK‐GARCH, CC‐GARCH, and OLS are compared with the use of aluminum and lead futures data. RCARRS outperforms all models out‐of‐sample for lead and is second only to BEKK‐GARCH for aluminum in terms of variancereduction point estimates. White's data‐snooping reality check null hypothesis of no superiority is rejected for BEKK‐GARCH and RCARRS for aluminum, but not for lead. © 2006 Wiley Periodicals, Inc.

Improving lattice schemes through bias reduction

Lattice schemes for option pricing, such as tree or grid/partial differential equation (p.d.e.) methods, are usually designed as a discrete version of an underlying continuous model of stock prices. The parameters of such schemes are chosen so that the discrete version “best” matches the continuous one. Only in the limit does the lattice option price model converge to the continuous one. Otherwise, a discretization bias remains. A simple modification of lattice schemes which reduces the discretization bias is proposed. The modification can, in theory, be applied to any lattice scheme. The main idea is to adjust the lattice parameters in such a way that the option price bias, not the stock price bias, is minimized. European options are used, for which the option price bias can be evaluated precisely, as a template to modify and improve American option methods. A numerical study is provided. © 2006 Wiley Periodicals, Inc. Jrl Fut Mark 26:733–757, 2006     

均衡性转移支付、公共支出结构与经济高质量发展

本文首先从理论层面系统阐述均衡性转移支付、公共支出结构与经济增长质量三者之间的多重作用机制。其次立足“五大发展理念”构建综合指标体系对经济增长质量展开测度，本文发现我国地方经济增长质量虽然在整体上呈缓慢上升态势，但其绝对水平相对偏低，且具有较为明显的地区异质性。最后本文通过构建动态面板联立方程模型与采取三阶段最小二乘法进行实证考察，结果表明：地方政府公共支出结构与经济增长质量显著正相关，但均衡性转移支付与经济增长质量的正相关关系并不显著。标准化回归结果显示均衡性转移支付能够通过优化公共支出结构对地方经济增长质量产生间接提升效应。
