网络流行语“中国大妈”和“中国式X”解析--基于认知及社会文化维度

伴随着新媒体的发展，“中国大妈”和与其结构类似的“中国式X”的网络流行语正在受到越来越多的关注。代表一种独特的文化现象的“中国式X”，本身就是一个语言模因，它的各种次生语言形式在模因的作用下得以在社会大众之间广泛繁殖和衍生。我们既可以从认知语言学的概念重叠和概念整合角度对“中国大妈”的形成及其所隐含的调侃语义进行解读，也可以从社会文化学领域的模因论视角对“中国式X”的传播进行探讨。     

Scale effects of R&D as reflected in earnings and returns

Using returns to scale as a conceptual foundation, we explore how R&D-related earnings performance and earnings variability depend upon firm size. We find that the positive association between the level of future earnings and R&D intensity increases with firm size, and that the positive association between the volatility of future earnings and R&D intensity decreases with firm size, consistent with R&D productivity increasing with scale. We also show that R&D scale is associated with lower market returns, consistent with the idea that R&D investment risk declines with scale.     

The effect of banking market structure on the lending channel: Evidence from emerging markets

This paper analyses the extent to which the level of bank competition influences monetary policy transmission. Using a large panel dataset of 978 banks from 55 countries, and employing the Lerner index model as a measure of market structure, our results show that an increase in banking sector competition weakens the effectiveness of monetary policy on bank lending. The findings are robust to a broad array of sensitivity checks including control of alternative measurements of the Lerner index, different samples and different methodological specifications. By extension, these results have important policy implications for regulators in assessing the effectiveness of monetary policy transmission mechanisms.     

Housing Allowance and the Rent of Low‐income Households

This paper analyses the effect of a housing allowance programme on the rent paid by assisted low‐income households. The data consist of 12,000 rental households in the free‐market and municipal sectors. The effect is estimated using the programme reform of 2002 as an instrument. The reform increased the allowance of the assisted households depending on housing characteristics, but it had little effect on the eligibility. Results suggest that in the private sector, one additional euro of allowance increases the rent of claimants by 60–70 cents. The effect is zero in the municipal sector, as rents are tied to the housing costs.     

Socioeconomic Determinants of Child Health: Empirical Evidence from Indonesia

This paper characterizes the socioeconomic determinants of child health using height‐for‐age z‐score (HAZ), a long‐run measure of chronic nutritional deficiency. We construct a panel data that follows children between ages 3 and 59 months in 1993 through the 1997 and 2000 waves of the Indonesian Family Life Survey. We use this data to identify the various child‐level, household‐level and community‐level factors that affect children's health. Our findings indicate that household income has a large and statistically significant role in explaining improvements in HAZ. We also find a strong positive association between parental height and HAZ. At the community level, we find that provision of electricity and the availability of paved roads are positively associated with improvements in HAZ. Finally, in comparison to community‐level factors, household‐level characteristics play a large role in explaining the variation in HAZ. These findings suggest that policies that address the demand‐side constraints have greater potential to improve children's health outcomes in the future.

Using survey data to resolve the exchange risk exposure puzzle: Evidence from U.S. multinational firms

This paper examines the effect of unexpected exchange rate movements on U.S. shareholder wealth. Empirical results based on a sample of 634 U.S. multinational firms (1) confirm previously reported evidence that the disaggregation of the worldwide trade-weighted U.S. dollar exchange rate index into seven region-specific trade-weighted indices increases the precision and significance of exposure estimates; (2) show that models assuming that changes in spot exchange rates are unanticipated are frequently misspecified and, thus, unable to correctly detect the impact of currency movements on firm value; (3) reveal that forward and survey expectations enable us to distinguish between the effect of ‘realized’ and ‘unexpected’ currency movements; and (4) reveal that investors making pricing and hedging decisions prefer to use the information contained in short-term forward and survey expectation rates to the information included in long-term forecasts.     

双循环格局下“引进来”与“走出去”能否纠正资本错配?——来自省级层面的经验证据

提高资本配置效率是加快构建双循环新发展格局的重要抓手。在测算分析中国各省份资本错配程度的基础上,通过构建面板数据模型实证检验了"引进来"与"走出去"的资本错配纠正效果。研究结果表明:中国大部分省份的资本错配程度呈下降趋势,但省域之间资本错配程度的非均衡性特征突出,中西部地区的资本错配程度明显高于东部地区;"引进来"与"走出去"有助于提高资本配置效率,起到纠正资本错配的效果;"引进来"与"走出去"战略能够有效地纠正中西部地区的资本错配,提高其资本配置效率,但其在东部省份的作用效果并不明显。在考虑反向因果和异常值的影响后,研究结论依旧稳健。     

企业国际化经营的市场进入方式选择

随着世界经济一体化进程的加快和我国成功地加入世贸组织,企业越来越普遍地从事国际化经营活动。正确选择市场进入方式是企业国际化经营成败的关键。本文着重分析了影响进入方式选择的主要因素,并基于这一领域的交易成本理论、组织行为理论、折衷理论等尝试构建了一个企业国际化经营的进入方式综合决策模型,以期对我国企业实施“走出去”战略提供有益的借鉴。
