信息经济学视角下农户对信息需求的困境

本文运用信息经济学基本理论对农户信息需求不足的问题进行了分析,认为农户信息搜寻成本过高、农业信息市场不完善、农户自身素质偏低是农户信息需求面临困境的主要原因。并在此基础上提出加强农户的组织化水平,建立、健全农业信息经纪人制度,开发针对基层农户的农业信息市场模式,加强对农户的基础教育和职业教育等措施以提高农户的信息需求水平。

“后危机时代”下对华反倾销的实证分析

随着全球金融危机的不断恶化,中国再度成为各国反倾销措施的"众矢之的"。这不仅严重影响我国的出口贸易,也阻碍着我国企业海外发展战略的实施。因此,本文从调查数量、发起国家、涉案产品、调查方式等多方面,综合分析近期对华反倾销的特点,进而揭示我国企业应对反倾销的几点启示。     

新一代信息技术能否成为动力变革的重要支撑?——基于新兴产业分类与企业数据挖掘的实证分析

新一代信息技术作为新一轮科技革命的核心,可以通过“产业机制”和“赋能机制”推动和支撑经济发展动力变革。本文收集14514家样本企业,通过文本分析挖掘比照《战略性新兴产业分类(2018)》重新划分样本企业行业归属。在此基础上,筛选高成长企业,将其行业分布与新一代信息技术及其他战略性新兴细分行业对比,并构造表征新一代信息技术的代理变量,就其与省域经济增长及全要素生产率的关系进行计量检验。结果表明:虽然战略性新兴产业企业在样本企业中占比仅为30%左右,但筛选出的高成长企业60%以上都归属于战略性新兴产业;高成长企业中又有60%~70%属于新一代信息技术产业及数字创意产业。面板分析结果显示,新一代信息技术对省域经济增长有着明显的促进作用,但并不能提升全要素生产率;新一代信息技术已成为促进我国经济发展动力变革的重要支撑,但主要是通过产业机制来实现。未来我国应着力进行生产组织、设施完善、人员培训等方面的适应性改造,发掘新一代信息技术赋能机制方面的潜力。

Engagement partner specialization and corporate disclosure transparency

This paper explores the association of audit partners' industry specialization with corporate disclosure transparency and the latter's informativeness. The distinctive institutional designs of partner signature requirement and Information Disclosure and Transparency Ranking System (IDTRS) adopted in Taiwan allow us to empirically address the issue. We posit and find that the rankings from the IDTRS are higher for firms audited by industry specialist engagement partners than for firms audited by non-specialist engagement partners. Additionally, the results show that the probability of informed trade (PIN) proxy for information asymmetry is negatively associated with the rankings for clients of industry specialist engagement partners, but not for clients of industry non-specialist engagement partners. The results are robust with respect to alternative estimation method and alternative measures of industry specialization. Overall, the evidence suggests that industry specialist engagement partners enhance the credibility of corporate disclosure transparency, through which information asymmetry is further declined. The evidence provides policy implications to the partner signature requirement adopted in Taiwan and China.     

The use of open source internet to analysis and predict stock market trading volume

The objective of this paper is to evaluate the impact of information demand and supply on stock market trading volume. Few studies have demonstrated the role of Google search data in analyzing trading volume activity. In this study, we employ a proxy for information demand which is derived from weekly internet search volume. The latest is from Google Trends database, for 25 of the largest stocks traded on CAC40 index, between April 2007 and March 2014. We use news headlines as a proxy for information supply. We use Garch model to analyze and predict trading volume.The empirical results present new evidences. First, information supply has an impact on trading volume but information demand's impact is much more important. Secondly, by applying MCA to results found, it could be concluded that the impact of public information on transaction volume is conditioned by two elements: the firm and market news disclosure and the second element relates to the characteristics of the market participants, more precisely their news interpretations and their risk aversion. Thirdly, we used Chow structural break test to verify the stability of our model. We found that for securities with structural changes, information demand is the responsible variable of the change in our model. Finally, we found that information variables have a predictive power on transaction volume.This paper contributes to existing literature by incorporating open source internet-based data into the analysis and prediction of transaction volume. Using internet information about the stock market, which has appeared recently as an interesting research for financial empiricists, computer scientists and practitioners, will have a very important utility because quantifying demand and supply of information becomes possible.     

Compulsory versus voluntary voting: An experimental study

We report on an experiment comparing compulsory and voluntary voting institutions in a voting game with common preferences. Rational choice theory predicts sharp differences in voter behavior between these two institutions. If voting is compulsory, then voters may find it rational to vote insincerely, i.e., against their private information. If voting is voluntary so that abstention is allowed, then sincere voting in accordance with a voter's private information is always rational while participation may become strategic. We find strong support for these theoretical predictions in our experimental data. Moreover, voters adapt their decisions to the voting institution in place in such a way as to make the group decision accuracy differences between the two voting institutions negligible. The latter finding may serve to rationalize the co-existence of compulsory and voluntary voting institutions in nature.     

New technology and old institutions: An empirical analysis of the skill-biased demand for older workers in Europe

Using panel data from nine European countries over the period 1970 to 2007, we examine the impact of information and communication technology (ICT) on the demand for older workers (aged 50 and over). We find evidence of a decrease in demand for older workers in the 1970s and 1980s. It can be argued that the impact of ICT on demand for older workers is skill-biased. However, the skill-biased demand for older workers is mainly reflected in the skill-biased changes in employment shares rather than relative wages. There is some evidence of a gradual deskilling of older workers. We find that labour market institutions such as the national minimum wage, social pacts on wage issues and union density mostly benefit skilled older workers, while coordination of wage setting, extension of collective agreements, social pacts on pensions and centralisation of wage bargaining can alleviate the adverse effects of skill-biased technological change.
