油价不确定性与企业投资

本文利用2000-2015年中国宏观经济数据和1998-2007年中国工业企业调查数据,从宏观和微观两种视角考察了投资对油价不确定性冲击的反应。宏观研究发现,油价不确定性冲击不仅能够解释约12%的固定资产投资波动,而且还对固定资产投资具有短期抑制效应。在微观层面,本文采用基于异质性折旧率计算得到的企业投资,发现油价不确定性冲击在短期内对民营企业和外资企业投资也有抑制效应,但是对国有和集体企业的影响不显著,这一结论随着企业折旧率异质性的程度提高将变得更加明显。进一步分析发现,与非国有企业相比,国有和集体企业的投资行为具有明显的政策导向性,特别是在“十五计划”实施以后,国有和集体企业的投资密度比非国有企业高出约2.1%。这种政策导向性的存在,使得国有和集体企业的投资对油价不确定性冲击的反应并不显著。     

From structural to transition effects: Institutional dynamism as a deterrent to long-term investments by MNEs

The effect of institutional change on foreign direct investment is often conceptualized through the lens of an improving or deteriorating level of institutional quality that alters transaction costs. However, in the context of comprehensive government intervention in the past decades, this perspective ignores the potential uncertainties and costs associated with the process of institutional change. We propose that institutional change causes structural changes in transaction costs as well as accompanying transition effects due to uncertainty and learning costs. The extent of such transition effects is linked to the process characteristics of institutional change, e.g., institutional dynamism. In this paper, we examine the effects of institutional dynamism on foreign direct investment in long-term capital commitments and hypothesize a negative relationship between institutional dynamism and FDI, and a moderating effect of institutional dynamism on the relationship between institutional quality and FDI. Using investment data by US MNEs aggregated on the host country level, we find support for our hypotheses with some qualifications. We derive implications for the middle-income trap discussion as well as the ongoing fast-paced transition towards a sustainable global economy that is bound to shift attention from differences in the level of institutional quality towards differences in transition processes.

Debt rescheduling and the choice between bonds and loans for LDCs' foreign debt

This paper examines less developed country (LDC) borrowers' choice of financing methods. I devleop and test the hypothesis that ex-ante consideration of rescheduling affects LDC borrowers' choice between bonds and commercial loans. Banks can monitor and distinguish between permanent and temporary shocks, while bondholders cannot. Therefore, debt rescheduling based on the nature of economic shocks is feasible with loan financing. Our empirical findings indicate the debt rescheduling is considered exante in LDC lending. In addition, default risk and contract size affect the choice of financing instruments.

What explains the value premium? The case of adjustment costs,operating leverage and financial leverage

This paper empirically examines and compares the different theoretical predictions on how adjustment costs, operating and financial leverage influence the value premium. Consistent with Ozdagli (2012), financial leverage plays a dominant role, supported by adjustment costs (which represent the degree of investment irreversibility). Specifically, the observed value premium is driven by the financial leverage differences between value and growth firms, partially neutralized by investment irreversibility. The relation between the value premium and investment irreversibility is contrary to the intuition in Zhang (2005) and Cooper (2006). Operating leverage does not significantly influence the value premium.     

Greening transportation fleets: Insights from a two-stage game theoretic model

The greening of organizational transportation fleets, especially trucks and automobiles, has gained increasing attention by companies in a variety of industrial sectors. The reasons for this concern and attention are due to regulatory and competitive pressures, but also increasing costs of fossil-fuels. Surprisingly the amount of research and modeling for fleet management overall has been rather limited, with the focus on managing green vehicle investments virtually non-existent. In this study we develop a two-stage game theoretic model that helps evaluate, from both policy and organizational perspectives, the implications of greening of transportation fleets. Various parameters are evaluated including factors such as innovations in green vehicle technology, levels of service differences, cost of fuel, adjusting tax policy, regulatory compliance requirements, and adaptation costs. This evaluation provides practical insights into actions that could be considered by regulators and organizations to encourage environmental investments.     

收益波动与随机冲击的非对称性影响：中国与美国股票市场的对比

通过讨论股票收益与随机;中击之间的关系,对中国股票市场和美国股票市场进行了对比研究。研究中使用了中国上海和深圳股票市场1990年12月31日至2005年12月30日的两市A股算术平均周指,以及美国股票市场1973年1月2日至2004年月12月30日的标准普尔500周指。在进行经验研究的过程中,分别使用了线性GARCH模型和GJR—GARCH模型计量股票收益的条件波动——即模型中的条件方差。研究发现,中国股票市场自1990年——1995年波动剧烈,之后波动趋于平缓,而美国股票市场在研究期间内收益波动一直处于一定范围内。同时还发现,美国股票市场的随机冲击对股票收益产生非对称性影响,即负冲击使股票收益产生的波动大于正冲击。而在中国股票市场却找不到相似的证据。鉴于对中国股票市场收益波动的研究结果,在剔除1996年以前的数据之后又进行了扩展研究,但是似然比率检验结果表明,正冲击对股票收益的影响还要略强于负冲击。     

跨越反倾销税的外国直接投资研究述评

征收反倾销税的目的是保护国内产业免受倾销的损害,但外国厂商通过直接投资方式跨越反倾销税壁垒,降低甚至消除了反倾销税对国内产业的保护效果,对东道国贸易与投资政策提出挑战。本文对国外关于反倾销税的外国直接投资效应、跨越反倾销税的外国直接投资对东道国国内企业的影响以及东道国政府的政策选择等方面的研究作简要述评。
