Intergenerational earnings mobility in Taiwan: 1990–2010

2020

Yu-Wei Luke Chu, Ming-Jen Lin

Empirical Economics, 59:11–45

In this paper, we study the intergenerational earnings mobility between fathers and sons in Taiwan. We apply the two-sample approach developed by Björklund and Jäntti (Am Econ Rev 87(5):1009–1018, 1997) and find that the intergenerational earnings elasticity in Taiwan was around 0.4–0.5 in both the early 1990s and the late 2000s. We also estimate the intergenerational rank association in earnings to have been around 0.3 in both periods. Intergenerational earnings mobility in Taiwan is similar to that in less mobile countries such as the USA, and it appears to remain stable during a period of rapid economic development.

Catching Cheating Students

2020

Ming‐Jen Lin Steven D. Levitt

Economica, 87(348), p885-900. (leading article)

We develop a simple algorithm for detecting exam cheating between students who copy off one another's exams. When this algorithm is applied to exams in a general science course at a top university, we find strong evidence of cheating by at least 10% of the students. Students studying together cannot explain our findings. Matching incorrect answers proves to be a stronger indicator of cheating than matching correct answers. When seating locations are randomly assigned, and monitoring is increased, cheating virtually disappears.

Content-Based Echo Chamber Detection on Social Media Platforms

2019

Fernando Henrique Calderon Alvarado, Li-Kai Cheng, Ming-Jen Lin, Yen Hao Huang and Yi-Shin Chen

in Proceedings of The 2019 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining, Vancouver, Canada, 27-30 August, 2019.

“Echo chamber” is a metaphorical description of a situation in which beliefs are amplified inside a closed network, and social media platforms provide an environment that is well-suited to this phenomenon. Depending on the scale of the echo chamber, a user’s judgment of different opinions may be restricted. The current study focuses on detecting echoing interaction between a post and its related comments to then quantify the predominating degree of echo chamber behavior on Facebook pages. To enable such detection, two content-based features are designed; the first aids stance representation of comments on a particular discussion topic, and the second focuses on the type and intensity of emotion elicited by a subject. This work also introduces data-driven semi-supervised approaches to extract such features from social media data.

Long-Term Impacts of Early Life Exposure to Malaria: Evidence from Taiwan in the 1950's

2018

Shih, Hsiu-Han and Ming-Jen Lin*

Health Economics, 27(10) pp1484-1512. (Cover Article)

This paper utilizes the eradication campaign in Taiwan in the 1950s to estimate the long‐term impacts of early‐life (in utero and postnatal) exposure to malaria. Matching adults in the 1992–2012 Taiwan Social Change Survey to the malaria intensity in their individual place and year of birth, difference‐in‐difference estimation shows strong evidence that the eradication increased men's own educational attainment as well as their family income in adulthood. We also use the 1980 census data to show there was a sharp education increase after the eradication. Furthermore, the eradication increased the educational attainment of married men's spouses. Finally, quantile regressions show that the effect concentrated on the lower percentile of the income distribution. Overall, our results suggest negative effects of early‐life exposure to malaria.

Does Anxiety Affect Adolescent Academic Performance? Inverted-U Hypothesis Revised

2017

Shih, Hsiu Han and Ming-Jen Lin*

Journal of Labor Research,38(1), pp45-81.

The inverted-U relationship between anxiety and performance in the context of endogeneity has yet to be investigated. Junior high school students from Taiwan were used as the sample for investigating the effect of anxiety levels on the comprehensive analysis aptitude of students. The ordinary least square (OLS) analysis indeed confirmed the inverted-U relationship. In addition, both fixed-effect analysis and two-stage least square (2SLS) analysis using variation in acne severity to instrument for anxiety also concluded that anxiety increased performance at lower anxiety levels. However, this relationship was positive and insignificant at higher anxiety levels. Overall, our results supported the left (increasing) part of the inverted-U relationship between anxiety and performance, but found no evidence for the right (decreasing) part of the inverted-U relationship.

入學管道與學習表現 (Multi-channel Admission and Academic Achievement)

2020

李維倫*、古慧雯、駱明慶、林明仁

經濟論文叢, 48(1), pp 31-76.

我們使用2007–14年間入學之台大學生的學籍資料、入學考試成績和在學成績,探討不同管道學生入學後的學業表現差異,並藉此評估多元入學政策在台大實施的成效。我們發現,以個人申請管道入學學生的學業成績雖然顯著優於透過指考入學的學生,但學測成績的差異即可解釋兩者入學後學業表現的大部分差異;控制學測成績後,申請生和指考生的學業成績並沒有顯著差異。而在轉系與退學的面向,申請、繁星生無論在轉系、成績因素退學和主動退學的比例,皆明顯低於指考生。在繁星計畫/繁星推薦方面,繁星生平均的學業表現優於申請生和指考生。這不只是來自明星高中繁星生的貢獻,非明星高中繁星生的學業表現平均而言也顯著高於指考生。然而如果只看來自2011–15年內無人以申請或指考進入台大的高中的繁星生,其學業成績則顯著低於指考生。此一差異也可以用學測成績的差異來解釋;控制學測成績後,這些繁星生和指考生的學業成績並沒有顯著差異。

經濟學門學術期刊評比更新: 2019 年(Ranking of Economics Journals: the 2019 Update)

2019

林明仁.林常青.張俊仁.曹添旺.楊浩彥

經濟論文叢刊,47(4), pp 503-542.

本文延續曹添旺等(2013)《經濟論文》的研究,秉持客觀的量化分析與主觀的質化觀點並重的期刊排序分析原則。在考量快速變遷的國際期刊市場之下,針對快速崛起的重要期刊,給予適當的排序。同時,我們也將重新思考國內期刊對學界的重要性,並考量本土議題對台灣經濟及政策的影響,進一步給予國內期刊在期刊評比上新的地位。

論家戶所得與資產對子女教育之影響—以1993-1995出生世代及其父母稅務資料為例 (Education Opportunity Inequality Across Income in Taiwan)

2019

沈暉智*、林明仁

經濟論文叢刊,47(3), pp 393-453.

本文探討親代所得與資產如何影響子代教育取得之機會。分析財稅資料中心2000–2015年之母體層級稅務資料,串連親代所得、資產及子代的就學資料後,發現家戶所得及資產與高等教育的就讀機會呈高度相關。台灣大學與公立學校的學生家戶年所得中位數分別超過150、100萬元,遠高於全體樣本中位數86萬元。進一步檢視各大專院校及學制的資產分佈,則凸顯不同學制間鉅額的財富差距及代際流動於教育管道的僵固。最後,各校每生平均教育經費支出與學生家戶所得組成間的正向關係,也凸顯了政府的教育經費補貼其實是反向重分配的事實。

身高對學生綜合分析能力的影響:以「台灣教育長期追蹤資料庫」為例 ( Effect of Height on Cognitive Ability in Adolescence: Evidence from Taiwan Education Panel Survey)

2013

林明仁、蔡欣純、丁心嵐*

經濟論文(台灣經濟學會年會特刊),  41(4)pp 507-558.

本文探討身高對學生綜合分析能力的影響。以綜合分析能力做為認知能力的代表,OLS結果顯示身高與認知能力呈正相關,並排除身高是反映自尊、人際支配、健康、社團經驗、非認知能力等影響認知能力的假設。為修正可能因內生性問題導致的估計誤差,我們使用傾向分數法與「初經年齡」做為工具變數加以修正。我們發現女生初經年齡較早者青春期身高較高,其認知能力也較高。本文結果說明青春期的認知能力受到發育快慢的影響,越早進入青春期發育的青少年,認知能力越好。身高則是反映發育的時間點,因此可作為認知能力高低的代理變數。

經濟學門學術期刊評比更新 (The Updated Ranking of Academic Journals in Economics)

2013

曹添旺*、王泓仁、林明仁、張俊仁、陳宜廷、黃粲堯

經濟論文,41(3), pp 327-361.

研究成果品質的判定,在高等教育與研究機構之學術表現評鑑,及內部人士聘用與升等上,都扮演著重要的角色。就經濟學門而言,期刊論文是最重要的研究成果出版形式,因此期刊品質的判定對經濟學門的發展十分重要。台灣過去幾年,已有不少針對國際期刊與本國期刊評比之論著,以及根據這些結果所計算出之學術單位表現。然而,相關研究發表至今,經濟學研究領域發生不少變動,也有許多新期刊快速興起;僅以SSCI資料庫收錄之經濟期刊而言,其收錄數也在近幾年從二百多種增加到三百多種。有鑑於此,本文爰採用文獻中新進提出的客觀量化排序方法、並參考傑出學者專家的意見,重新對當前的國際及國內經濟學期刊加以評比排序,俾供參考。
