What is the major determinant of cross-border banking flows?

This study examines the major determinant of cross-border credit flows through global banks across 70 countries. Employing a Bayesian dynamic latent factor model, we decompose volatilities of banking flows into the contribution of a global common factor, regional common factor, and country-specific factor. The results indicate that the global and regional common factor explains about 40–50 percent of volatility in overall cross-border banking flows. In particular, the contribution of the global common factor increased in the 2000s. Simultaneously, main determinants are largely heterogeneous across countries: this implies that the desirable policy response to credit inflows may differ for each host country.

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。     

开发农村人力资源是解决“三农”问题的根本

WIC Participation and Relative Quality of Household Food Purchases: Evidence from FoodAPS

We examine the effect of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) on the quality of household food purchases using the National Household Food Acquisition and Purchase Survey (FoodAPS) and propensity score matching. A healthy purchasing index (HPI) is used to measure nutritional quality of household food purchases. WIC foods explain the improvement in quality of food purchases, not self‐selection of more nutrition‐conscious households into the program. The improvement in purchase quality was driven entirely by WIC participating households who redeemed WIC foods during the interview week. There was no significant difference between WIC participants who did not redeem WIC foods and eligible nonparticipants. In this sample, there is no evidence that lack of access to clinics has adverse effects on participation nor is there evidence that HPI depends on supermarket access. A supervised machine learning process supports our main conclusion on the importance of WIC foods.     

GPT3模型计算中国大陆对流层天顶延迟精度分析

为了评估GPT3模型计算中国大陆对流层延迟改正的精度和可靠性,利用2017-2018年欧洲中期天气预报中心的ERA-Interim大气廓线资料和中国地震局提供的陆态网对对流层延迟产品进行了对比验证分析。结果表明,在中国大陆,GPT3-ZTD模型值的年均偏差(Bias)小于0.6 cm,均方根误差(RMSE)优于3.53 cm。ZTD模型值的精度总体呈现出从中国西北(RMSE3 cm)到东南地区(RMSE5 cm)逐渐降低的趋势;在中国东南地区,GPT3模型低估了对流层天顶延迟,其量级处于-2.0～0.5 cm。ZTD模型值的精度与测站高程呈非线性相关,随着高程增加而精度不断提升。此外,GPT3-ZTD的精度具有明显季节性变化,RMSE基本维持在1～6 cm,ZTD模型值精度的季节性变化与大气中水气含量和变化剧烈程度相关。GPT3模型对中国大陆的对流层天顶延迟计算有较好的精度和可靠性,可为中国大陆对流层延迟改正建模提供一定参考。     

THE IMPACT OF GREATER AUTONOMY ON EFFICIENCY OF WORK AND QUALITY OF SERVICES IN PUBLIC SERVICE PROVIDERS: A CASE OF VOCATIONAL EDUCATION INSTITUTIONS

ABSTRACT: The paper analyses impact of greater autonomy on efficiency of work and quality of services in public service institutions. Autonomy is one of the key principles of New Public Management that, according to the theory, increases performance in public service providers. However this assumption has been scarcely researched in practice. To narrow this gap, the experimental reform that implemented greater managerial and financial autonomy in 13 Lithuanian state vocational schools was chosen for research. In order to analyse the impact of autonomy after the reform, maximally similar institutions (those that underwent the reform and that did not) are compared using quantitative (incl. counterfactual analysis) and qualitative methods. The results indicate that institutions that have been reformed tend to have better efficiency and quality of services, even though this relationship is not causal. Moreover, the research challenges the notion that such results came from greater autonomy. Finally, the logic of the NPM of as to why more autonomous institutions perform better is also challenged.     

我国自愿环境协议的第三方主体选择及其职能安排刍议

自愿环境协议在环境管制的实务中得以流畅运用,政府与企业以外的第三方主体对企业环境绩效所进行的评估功不可没。在我国,可由政府对从事环境服务业的法人实体开展资质认证,依此判断这些组织机构是否具备为协助政府与企业实施自愿环境协议所必要的环境审计能力,并根据所获得的结论建立第三方协议参与者官方认证资源库。通过认证的第三方在自愿环境协议中负责对企业进行环境审计、环境目标执行计划书评审和履约绩效监督,企业购买此类环境服务的费用享受公共财政的支持。
