东亚区域经济周期及其同步性研究

本文运用动态因子模型和B-B算法,以1993q1-2008q3时间段内GDP季度数据为基础,考察了东亚十国(地区)共同经济周期及其具体特征.再根据动态因子模型得到的参数,比较了东亚各国(地区)和共同经济周期的相关性.我们发现,除中国和共同周期的关系不大,东亚其他国家(地区)和共同周期的关系比较紧密.     

The Valuation of Insurance under Uncertainty: Does Information about Probability Matter?

In a laboratory experiment we test the hypothesis that consumers' valuation of insurance is sensitive to the amount of information available on the probability of a potential loss. In order to test this hypothesis we simulate a market in which we elicit individuals' willingness to pay to insure against a loss characterised either by known or else vague probabilities. We use two distinct treatments by providing subjects with different information over the vague probabilities of loss. In general we find that uncertainty about probabilities has a weak impact on consumers' valuation of insurance. However, additional information about probabilities tends to marginally increase the price individuals are willing to pay to insure themselves. Implications for the insurance market are derived.     

A trivariate model of participation,fertility and wages: the Italian case

Italy has unusually low fertility by OECD standards, accompaniedby unusually low female participation in paid work. This paperaddresses the issue of the empirical relationship between fertility,female participation in the labour market and wages with theseItalian 'peculiarities' as a backcloth. A trivariate model ofparticipation, fertility and wages has been constructed andestimated using three pooled cross-sections of Italian microdata, allowing for the identification of cohort effects. Thismodel follows a 'purist' approach: the participation and fertilitydecisions, as well as the wage equation, are modelled as completelyjoint. The cohort effects turn out to be significant: the pointestimates do not appear to confirm actual trends, which arenegative for fertility and positive for participation. The femalewage is the most important variable influencing the propensityto have children and the propensity to participate in the labourmarket, casting doubt on suggestions that observed trends arethe products of shifts in women's 'tastes'.

WTO与就业

中国入世后必然会对我国就业状况产生影响:就业市场结构性失衡;对各产业吸纳劳动力的影响不同;短期内将带来失业压力;长远看增加就业总量。对此,我们应采取相对措施:控制劳动力供给;扩大劳动力需求;加快劳动力流动和转移。     

Treatment effects of selection behavior in managed care plans: evidence from Medicaid

This paper tests whether capitated payments to Medicaid managed care plans induce to plans strategic undercutting of treatment for specific diagnostic groups. I focus on treatment (measured by length of stay and cost) in acute care hospitals in Massachusetts. I use a differences-in-differences-in-differences approach, where the third differences compare treatment patterns between managed care plans that receive capitated payments with those that do not. I find that the first reduce treatment significantly more to mental health patients than to patients in other disease groups, whereas the latter reduce hospital resource use more uniformly across disease groups. These results highlight the importance of using payment mechanisms in public programs that reflect the variability in costs of beneficiaries.Received: September 2002, Accepted: May 2003, JEL Classification: I11I thank Randall Ellis, Kevin Lang and Thomas McGuire and anonymous referees for valuable comments and suggestions.

Factors affecting global integration of Chinese multinationals in Australia: A qualitative analysis

This study utilizes cross-level and in-depth interviews to extend empirical and conceptual studies that have identified the factors underlying the choices made by OECD based multinational enterprises (MNEs) when determining their approach to global integration. The study examines the applicability of these factors in the context of Chinese MNEs with operations in Australia. In so doing, it pioneers the use of qualitative methods to determine which factors affect emerging market MNEs’ global integration and how these elements function and interrelate. Furthermore, the study contributes to theory-building by classifying the factors affecting global integration into organizational, industrial, and environmental groupings. The implications of this study are drawn from the data analysis and directions for future studies are advanced.
