1.	趙彤, 石田基広, 服部恒太 : 中国P2Pネット金融における差別, パーソナルファイナンス研究, Vol.7, 13-24, 2020年. (要約) <p>中国のP2P ネット金融は，ここ10 年の間，大きく成長してきた．本稿では大手P2P ネット金融プラットフォームである「人人貸」(RRD)の取引レコードを用いて，借手の非金融的属性(年齢，性別，婚姻状況など)がローン証券の成約，デフォルト及び収益に与える影響を3つの統計モデルに基づき分析した．結果として，標準的な経済学の理論に反し，統計モデルではローン証券の成約，デフォルト率と収益率に借手の非金融的属性が有意に効いていることが確認できた．これは貸手がローン証券に投資する際，借手の非金融的属性を積極的に利用していることを意味し，借手の非金融的属性が金融的属性と同じ，貸手にとっては非常に重要な借手情報である．さらに，性別，学歴，婚姻状況と勤務所在地に対する差別は合理的な統計的差別(Statistical Discrimination)に対して，年齢に対する差別は非合理的選好による差別(Taste-based Discrimination)と判別することができた．</p> (キーワード) P2Pネット金融 / 地域金融差別 (出版サイトへのリンク) ● Publication site (DOI): 10.20752/japf.7.0_13 (文献検索サイトへのリンク) ● CiNii @ 国立情報学研究所 (CRID): 1390289564745064320 ● Search Scopus @ Elsevier (DOI): 10.20752/japf.7.0_13 (DOI: 10.20752/japf.7.0_13, CiNii: 1390289564745064320)

(要約) Native speakers of Japanese often have difficulty identifying English /r/ and /l/, and it has been thought that second-language (L2) learning difficulties like this are caused by how L2 phonemes are assimilated into ones native phonological system. This study took an individual difference approach to examining this relationship by testing the category assimilation of Japanese speakers with a wide range of English /r/-/l/ identification abilities. All Japanese subjects were assessed in terms of (1) their accuracy in identifying English /r/ and /l/, (2) their assimilation of /r/ and /l/ into their Japanese flap category, (3) their production of /r/ and /l/, and (4) their best-exemplar locations for /r/, /l/, and Japanese flap in a five-dimensional set of synthetic stimuli (F1, F2, F3, closure duration, and transition duration). The results demonstrated that Japanese speakers assimilate /l/ into their flap category more strongly than they assimilate /r/. However, there was little evidence that category assimilation was predictive of English /r/-/l/ perception and production. Japanese speakers had three distinct best exemplars for /r/, /l/, and flap, and only their representation of F3 in /r/ and /l/ was predictive of identification ability.
