A note on the equivalence of specification tests in the two-factor multivariate variance components model

This note offers a generalization of Hausman and Taylor's equivalence of specification tests in the single-equation variance (error) components model to the two-factor multivariate variance components case. The relationship between the specification tests and the hypothesis test in the model proposed by Mundlak is also discussed.     

Has bank consolidation in Korea lessened competition?

This paper examines market concentration and competition in the Korean commercial banking market for the period of 1992–2004. While market concentration decreased due to financial regulation before the Asian financial crisis, the Korean banking industry has become increasingly concentrated in the process of restructuring and consolidation since the crisis. Contrary to a growing concern over market power in Korean banking, this study finds that increased concentration has not lessened competition. The H statistic of the Panzar–Rosse model indicates that the Korean commercial banking market was monopolistically competitive during the pre-crisis period and the post-crisis period with temporary deviation to the level of perfect competition during the crisis period.     

民营企业R&D支出与企业价值关系实证研究——基于中小板和创业板市场数据

本文利用中小板和创业板上市的中国民营企业数据,通过实证分析研究了R&D支出与企业价值的关系。首先通过内含假设不同年份R&D投入有一定相关性,来检验平均研发投入对企业价值的估值效应,得出了对这一特殊的样本,两者显著正相关,同时得出民营企业R&D投入强度远高于市场平均值。然后通过内含假设不同年份R&D支出本身无太大关联性,来分析研发投入对价值影响的滞后性,得出结论民营企业研发支出对企业价值影响滞后至少2年。本文克服了以往此方面研究数据和内含假设模糊地局限性,旨在为评价中国这一部分发展潜力巨大的民营企业的价值提供更客观的依据。

Can commodity futures risk factors predict economic growth?

This paper examines whether commodity futures risk factors can predict future economic growth. We test risk factors capturing various spot or term premia and find that only three factors capturing term premia on the basis-momentum, basis, and change in slope are robust predictors for future economic growth, especially for long horizons. Our findings highlight the importance of the term premia, rather than the spot premia on which the literature has mainly focused. Moreover, we find that possible explanations for predictability of commodity factors—the intertemporal asset pricing model and information diffusion explanation—are all inconsistent with our empirical results.

意义、困境与向路:我国地方人大立法协商研究

立法协商是地方人大实现科学立法、民主立法和依法立法的有效途径和重要举措。随着我国立法实践的发展,虽地方立法协商工作取得了卓著成效,但也存在着诸多待解难题,如立法协商主体角色定位不清、实现过程有待明确、意见收集渠道缺失等。鉴于此,地方人大立法应充分体现地方人大主导地位、实现立法协商制度化规范化、紧紧依靠人民群众开展立法协商,进而以协商民主的方式为地方立法工作凝聚共识、汇集民智。
