An alternative estimator for multiple characteristics in PPS sampling

The problem considered relates to large-scale sample surveys. A new estimator of population total for the characteristics that are poorly correlated with the selection probabilities has been developed for the PPSWR sampling scheme. The relative efficiency of the proposed estimator has been studied under a super-population model. A numerical investigation into the performance of the estimator has also been made.

PRICE‐LEVEL CHANGES AND THE REDISTRIBUTION OF NOMINAL WEALTH ACROSS THE EURO AREA

We show that unexpected price‐level movements generate sizable wealth redistribution in the Euro Area (EA), using sectoral accounts and newly available data from the Household Finance and Consumption Survey. The EA as a whole is a net loser of unexpected price‐level decreases, with Italy, Greece, Portugal, and Spain losing most in per capita terms, and Belgium and Malta being net winners. Governments are net losers of deflation, while the household (HH) sector is a net winner in the EA as a whole. HHs in Belgium, Ireland, Malta, and Germany experience the biggest per capita gains, while HHs in Finland and Spain turn out to be net losers. Considerable heterogeneity exists also within the HH sector: relatively young middle class HHs are net losers of deflation, while older and richer HHs are winners. As a result, wealth inequality in the EA increases with unexpected deflation, although in some countries (Austria, Germany, and Malta) inequality decreases due to the presence of relatively few young borrowing HHs. We document that HHs' inflation exposure varies systematically across countries, with HHs in high‐inflation EA countries holding systematically lower nominal exposures.     

THE DYNAMICS OF CLIMATE AGREEMENTS

This paper analyzes a framework in which countries over time pollute and invest in green technologies. Without a climate treaty, the countries pollute too much and invest too little, particularly if intellectual property rights are weak. Nevertheless, short‐term agreements on emission levels then reduce every country's payoff, since countries invest less when they anticipate future negotiations. If intellectual property rights are weak, the agreement should be tougher and more long‐term. Conversely, if the climate agreement happens to be short‐term or absent, intellectual property rights should be strengthened or technological licensing subsidized.

P2P网络借贷机构的系统重要性研究

互联网金融发展得如火如荼,其蕴藏的风险不容忽视。由于P2P网络借贷是互联网金融的一项重要业态,且其风险溢出效应较大,研究其风险监管有着非常重要的意义。通过借鉴巴塞尔委员会对系统重要性银行识别的指标体系,基于指标法的思想联系我国互联网金融发展现状以及P2P网络借贷机构的特征对指标体系进行了合理改进。对国内比较重要的P2P网络借贷机构进行了系统重要性排名,并且和以前的研究成果进行了比较。对于推动互联网金融分类适度的监管工作有着一定的意义。
