Productivity Spillovers from FDI in Malaysian Manufacturing: Evidence from Micro‐panel Data*

Using an establishment‐level panel dataset for the Malaysian manufacturing industries for 2000–2004, we argue that differences in the proxies and degrees of foreign shareholdings in measuring foreign presence lead to opposite signs and/or significance of spillover effects. The results show significant evidence of positive productivity spillovers to local establishments in the same industry, based on a broad measure of foreign presence. However, there is no evidence of positive spillover when employment share is used as a proxy for foreign presence. Furthermore, significant negative spillover effects are related to higher employment shares of wholly foreign‐owned establishments. Although there is no significant difference in labor productivity between wholly foreign‐owned and locally‐owned establishments, both majority and minority foreign‐owned establishments have significantly lower levels of labor productivity than locally‐owned establishments in Malaysia.     

基于IPv6任播地址解析协议及应用之研究

任播技术是一种新的网络应用。任播通信是支持导向服务地址的,但是目前IPv6中它的很多定义是模糊的,并且在控制路由方面没有达成一致的协议标准,因此节点间任播通信仍然无法实现。该文首先说明了基于IPv6的任播通信,及目前在该领域中存在许多可能的应用,并指出一些问题和与之对应的解决办法,随后介绍了一种使用特殊任播地址来建立TCP连接的任播地址解析协议,使得任播地址在适应已经存在的应用和高层协议时,不需要修改或者扩展的情况下更加有效。     

氟硅酸泵的国产化实践

硅氟酸极具腐蚀性 ,考虑到经济性 ,2 0 #合金、哈氏合金、蒙乃尔等贵金属很少被选为泵材。由于橡胶、塑料等高分子材料具有很好的抗蚀性和一定的机械性能 ,且价格便宜 ,因此一般选用其作为泵体材料。我们通过分析、比较 ,成功选择国产氟硅酸泵替代国外进口泵 ,实现国产化。     

In or out? explaining state shares of the tobacco Master Settlement Agreement

In 1998, 46 states were involved in a Master Settlement Agreement (MSA) with the tobacco industry. The other four states settled on their own. Our goal is to answer a counter factual question: how would these four states have fared had they been included in the MSA? We use data from Viscusi (2002 Viscusi WK (2002) Smoke‐Filled Rooms Chicago University of Chicago Press  [Google Scholar]) to explain settlement shares for states participating in the 1998 tobacco MSA, and to predict settlement shares for the four nonparticipating states. We find that two nonparticipating states (Minnesota and Mississippi) may have fared substantially worse had they been included in the MSA.     

Cooperative fiscal policy at the zero lower bound

This paper investigates the use of fiscal policy in response to a large negative aggregate demand shock which may push the global economy into a liquidity trap. Fiscal policy may be an effective tool to respond to a liquidity trap, but its international spillover effects may operate quite differently from its domestic effects. We derive the optimal cooperative fiscal response to a global liquidity trap in a two country world economy. Surprisingly, we find that the optimal fiscal spending response for a partner country to a negative aggregate demand shock in a source country may be negative. If fiscal policy can be chosen under policy commitment, the optimal response involves current fiscal expansion combined with future fiscal contraction, after the liquidity trap has ended.     

Job Search and the Measurement of Unemployment in South Africa

We interrogate the distinction between searching and non‐searching unemployment in South Africa using data from the first national panel survey that tracks the individual. In particular, we test whether the non‐searching unemployed display a weaker commitment to the labour market than the searching unemployed, and we investigate what counts as search activity. We find that over the panel, the search status of the unemployed does not predict their subsequent employment status, a result that is robust also for subsamples that vary by age cohort, gender and location. Moreover, social networks are the most important job‐finding strategy of the employed. These findings challenge the exclusion of the non‐searching unemployed from the measure of “genuine” work seekers.     

Two Pitfalls of Linearization Methods

This paper illustrates two types of pitfalls when linearization methods are improperly applied. First, if we linearize the constraints before deriving the optimality conditions, the derived conditions are not correct up to first order. Second, even when we obtain the behavior of the economy that is correct to the first order, applying this behavior to welfare implications may lead to incorrect results. We also review different ways to avoid those pitfalls.     

基于4C理论的汽车营销6C模型研究

随着我国汽车行业的迅猛发展,汽车产品和品牌日益丰富,客户需求也日益提高,我国汽车产业的格局发生了巨大的变化。目前,我国汽车营销正处于大洗牌的时期,在这一时期中,为了寻求发展,很多汽车企业都引入了市场营销中广为流传的4C理论。但是随着这一理论的广泛引用,很多内容已经不适用于当今汽车营销的发展。因此,需要对这一理论进行完善。在这一背景下,笔者提出了汽车营销的6C模型。     

Fiscal Policy in a Currency Union at the Zero Lower Bound

This paper constructs a two‐country core–periphery New Keynesian model of a currency union to address the interaction between the objectives of regionally directed fiscal policy constrained by a single currency and the aggregate use of fiscal policy in face of the zero lower bound (ZLB) on policy interest rates. We identify an optimal path of aggregate and relative fiscal policy responses to a negative region‐specific demand shock. Our results show that (i) in a monetary union, the optimal policy response to an asymmetric reduction in demand concentrated in the periphery always entails a relative shift of fiscal expenditure toward the worse‐affected regions, (ii) though no aggregate fiscal response is required outside the ZLB, and (iii) optimal union‐wide fiscal policy is expansionary at the ZLB. Therefore, optimal policy always entails an expansion in the periphery at the ZLB, but the optimal fiscal response in the core regions can be either expansionary or contractionary depending on the parameters of the model. However, (iv) fiscal expansion in the core is warranted if the periphery cannot implement an expansion due to constraints on public spending.     

Funded pensions and intergenerational and international risk sharing in general equilibrium

We explore intergenerational and international risk sharing in a general equilibrium multiple-country model with two-tier pensions systems. The exact design of the pension system is key for the way in which risks are shared over generations. The laissez-faire market solution fails to provide an optimal allocation because the young cannot share in the financial risks. However, the existence of wage-indexed bonds combined with a pension system with a fully funded second tier that pays defined wage-indexed benefits can reproduce the first best. If wage-indexed bonds are not available, mimicking the first best is not possible, except under special circumstances. We also explore whether national pension funds want to deviate from the first best by increasing domestic equity holdings. With wage-indexed bonds this incentive is absent, while there is indeed such an incentive when wage-indexed bonds do not exist.
