Trade liberalization in services: Investor responses to NAFTA’s cross-border trucking provisions

ABSTRACT

We investigate the response of US trucking firms to the removal of barriers to cross-border trucking under NAFTA. This was done via a program implemented in 2007, cancelled in 2009, and reinstated in 2011. We use a model of endogenous exporting to show that this can arise from incorrect expectations of import competition. We find that, unsurprisingly, the program’s start resulted in lower stock returns, particularly for border firms. However, later policy changes indicate that investors, and particularly those investing in US multinationals, viewed the pilot as beneficial.     

论中国地方保护主义的特点和效应

地方保护主义在产品市场和资金市场上有不同的形式和特点,具有产业针对性和地区针对性。不同地区的保护程度、保护手段和保护方式也不一样。从短期和局部来看,地方保护主义是有一定益处的,但从长期和全局来看,它会导致效率的降低、分配的不公平乃至整个国家经济的衰败和没落。

Environmental Requirements,Knowledge Sharing and Green Innovation: Empirical Evidence from the Electronics Industry in China

Building on the Porter hypothesis, which posits that regulatory stringency triggers innovation and thereby allows firms to achieve the dual purpose of environment protection and enhanced business performance, the present research develops an integrative model that explores the determinants of green innovation with a focus being placed on knowledge sharing. Data were collected from 203 green innovation project leaders from electronics manufacturers operating in China. The results indicate that knowledge sharing mediates the relationship between green requirements and new green product success as well as that between green requirements and green product and process innovations. Interestingly, the empirical analysis rejects the hypothesized positive influence of green requirements on green product and process innovations as well as that on new green product success, while confirming that there exists a direct and positive association between green requirements and knowledge sharing. The direct positive impact of knowledge sharing is the strongest on green process innovation. This study provides a theoretical basis for investigating the possible determinants in the causal links between green requirements and green innovation success and establishes that knowledge sharing and green process innovation may be the points where leverage can be applied to best secure innovation success. Implications of the findings on environmental policy and law design are also discussed to see how the regulatory role of the government can be better positioned to facilitate compliance and innovation.

中国职业体育工作者环保素质现状调查与分析

采用文献资料法、问卷调查法等方法对中国大陆31个省市的1082名职业体育工作者的环保素质进行了调查与分析。结果表明:中国职业体育工作者的环保意识较强、环保态度积极;但对环保知识的了解有限,参加环保活动的主动性不足;缺少维护环境,参与环保的行为;此外,对环境状况缺乏应有的关注也是现阶段存在的问题之一。总体来看,职业体育工作者整体的环保素质仍需加强,高、低学历者间在环保知识、环保意识等方面具有显著差异。在调研分析的基础上,还针对性的提出了补充环保知识,增强环保意识,坚定环保态度,改善环保行为,从而提高我国职业体育工作者环保素质的若干具体建议。     

我国债权人利益法律保护的评价体系研究

关于对债权人利益的法律保护评价,大多数文献都沿袭了LLSV的范式。该文发现这种范式并不完全适合像我国这样制度不断变迁的国家,因此对LLSV的评价体系进行了拓展,即,将除破产制度以外的合同制度、独立法人制度、信息制度、担保制度、信用制度纳入进来。在此基础上,对我国改革开放三十年来的债权人利益保护评价体系做了动态的考量,同时也对当前的这一制度状况进行了客观的评价。     

ENVIRONMENTAL DYNAMICS AND THE LINKS BETWEEN GROWTH,VOLATILITY AND MORTALITY

I construct a model of a growing economy with pollution. The analysis of the model shows that the interactions between capital accumulation, endogenous lifetime and environmental quality determine both the long‐run growth rate and the pattern of convergence (i.e., monotonic or cyclical) towards the balanced growth path. I argue that such interactions can provide a possible explanatory factor behind the, empirically observed, negative correlation between growth and volatility. Furthermore, the model may capture the observed pattern whereby economic growth and mortality rates appear to be negatively related in the long run, but positively related in the short run.
