薪資的性別歧視問題, 一直是勞動經濟學者所關心的議題, 一但存在薪資上的性別歧視, 將會影響到勞動市場的有效運作。 在完全競爭的勞動市場中, 受雇於類似工作, 而且生產力類似的工人, 應得到類似的工資。 但我們發現在現實生活中, 因為性別不同而造成勞動市場普遍存在著同工不同酬的情況, 我們稱為薪資的性別歧視。 在台灣, 已經有很多實證研究利用橫斷面的資料來證實台灣的勞動市場存在著性別歧視的現象。 但是似乎較少相關文獻使用追蹤資料 ( Panel data ) 來做類似的研究, 主要原因可能是國內目前尚缺乏完整的追蹤資料庫可供使用, 因為追蹤資料的形成極耗費時間及成本。 不過, 追蹤資料的使用價值極為豐富, 除了可以得到經濟個體的跨時選擇行為的資訊, 而且使用追蹤資料可以控制個人不隨時間變動且無法被觀察到的特性。 本論文使用中央研究院調查研究專題中心所製作的台灣擬追蹤調查資料庫 ( Taiwan Quasi Longitudinal Data Archive ) 中的人力運用擬 - 追蹤調查資料庫 ( 年資料 ), 由於人力運用擬-追蹤調查資料庫的產生, 使得用追蹤資料來分析的研究變的可行, 故本論文嘗試使用此擬追蹤資料庫, 來探討薪資的性別歧視問題。 本論文透過薪資差異分解方程式, 了解不同性別之間的薪資差異中, 可解釋的部分是受到本身教育程度、工作經驗、居住地區、職業別、行業別的差異所造成, 其餘不可解釋的部分則歸因於勞動市場的性別歧視。 本論文發現台灣自1979年到2000年, 男性平均薪資所得較女性為高, 兩性薪資差異有逐漸縮小的趨勢, 但性別歧視的問題卻越來越嚴重, 且造成台灣男女薪資差異縮小的原因, 可能為男女生產力差異的縮小, 而非性別歧視的減輕。

This thesis consists of three self-contained essays about immigrants’ experiences in Sweden. They all focus on the interaction between institutional settings and effects on immigrants’ economic conditions. Essay I examines the effects of changed eligibility rules for disability pension in the 1979 Swedish pension reform on immigrant retirement behavior. The reform made disability pension in the form of basic pension available to a wider group of immigrants. Before the pension reform, the eligibility for a basic pension for foreign citizens living in Sweden was dependent on bilateral and multilateral agreements on social security between Sweden and other countries. Thus, immigrants who were not covered by any of these agreements had no access to a basic pension before the reform. Through the reform, all foreign citizens residing in Sweden were made eligible for a basic pension after a short qualification period. The results indicate a substantial impact on the retirement rate with disability pension on the immigrant group that was made eligible for a basic pension by the reform. These findings confirm previous research showing that the size of the benefit levels in the pension system affects early retirement behavior. Essay II analyzes the impact of the Swedish taxi and bus deregulations on the differences in labor earnings between Swedish born and foreign born workers in these sectors. The changes in the gap in labor earnings that are due to the deregulation are estimated. The results show that there was no significant decrease in the differences in labor earnings between Swedish born and foreign born workers in the bus sector as a result of the 1989 deregulation. As regards the taxi sector, the results show that, before the deregulation, there were only small differences in labor earnings between Swedish born and foreign born workers. After the deregulation, the real labor earnings of foreign born workers decreased substantially more than those of Swedish born workers. However, there was a larger increase in the inflow of foreign born workers than of Swedish born workers into the taxi sector after the deregulation, which may have changed the composition of immigrant workers in this sector. Essay III investigates the impact of becoming a Swedish citizen on annual labor earnings. The study finds a positive impact of naturalization on labor earnings, in particular for immigrants originating from Africa and Asia, an effect than cannot only be attributed to selection into citizenship. A clear trend of increasing labor earnings during the years before becoming a Swedish citizen is found. This trend also continued during the years after citizenship acquisition. The study also suggests that the effects of naturalization on labor earnings are larger for men than for women, and larger for individuals with very low income.

<p>I denna uppsats undersöker vi huruvida invandrare diskrimineras på den svenska arbetsmarknaden. Vi undersöker även om förhållandet skiljer sig när vi endast tittar på gruppen kvinnor, och gör en jämförelse mellan svenskfödda kvinnor och invandrarkvinnor. Vi använder oss av två modeller för att estimera löneskillnader, dummyvariabel modellen och Blinder-Oaxaca modellen. Våra resultat ger tydliga indikationer på lönediskriminering gentemot invandrare, kvinnor och en ännu tydligare lönediskriminering gentemot invandrarkvinnor. Vi anser att invandrarkvinnor drabbas av en så kallad dubbel diskriminering, där den övriga populationen i genomsnitt ges 28,4% högre lön än invandrarkvinnor.</p> / <p>In this thesis we investigate whether immigrant are being discriminated on the Swedish labor market. We also examine if this differentiates itself when we put our focus on the women as a group and thereafter make comparison between Swedish born women and women born outside Sweden. We have employed two models in order to determine wage differences, the dummy variable model and the Blinder-Oaxaca model. Our results show a distinct indication of wage discrimination against immigrants, women and even a more comprehensive discrimination towards immigrant women. Immigrant women have in general 28,4% lower wage than the average population. According to our findings therefore, foreign women are subjects to double discrimination.</p>

The first three papers of this Ph.D. thesis experimentally study the preferences of individuals making cross-border charitable donations. In Is Foreign Aid Paternalistic? (with Anna Breman and Felix Masiye) subjects choose whether to make a monetary or a tied transfer (mosquito nets) to an anonymous household in Zambia. The mean donation of mosquito nets differs significantly from zero, and paternalistic donors constitute a higher share of the sample than do purely altruistic donors. The second paper, Corruption and the Case for Tied Aid (with Anna Breman), compares the willingness to give money to Zambia's national health budget (CBoH) with the willingness to donate mosquito nets to a health-care clinic in Lusaka. Donors clearly prefer tied aid to untied program aid. Exit questionnaires suggest the reason to be a fear of corruption and misallocation at the CBoH. In Altruism without Borders? (with Anna Breman), we study whether the willingness to give increase with the information given about the recipients. We find no significant effect of identification on donations. Women and Informality: Evidence from Senegal, the fourth paper (with Elena Bardasi), uses household survey data to study women’s work and gender wage gaps in the formal and informal sector in Dakar. Multinomial logit analysis reveals that women are 3-4 times less likely to work formally rather than informally. Wage regressions reveal that little schooling, for instance, explains a considerable part of the gender wage gap. In the informal sector, however, the wage gap between men and women remains at 28%.    The fifth paper, Does Innovation Pay? A Study of the Pharmaceutical Product Cycle, examines how a drug’s life cycle depends on its degree of therapeutic innovation. All New Chemical Entities introduced in Sweden between 1987 and 2000 are rated into one of three innovation classes: A (important gains); B (modest gains); and C (little gains). Over a 15-year life cycle, the average class A drug raises 15% higher revenues than B drugs and 114% higher revenues than C drugs. But yearly class A and C sales differences are rarely significant. When comparing innovative (A and B pooled) and imitative (C) drugs, 15-year life cycle revenues of innovative drugs exceed those of imitative drugs by 100%. This sales difference is significant in 19 out of 20 years after launch. / Diss. Stockholm : Handelshögskolan i Stockholm, 2008 Sammanfattning jämte 5 uppsatser

Mit dem Begriff Diskriminierung wird der benachteiligende, herabsetzende oder abwertende Umgang mit Personen, die (imaginierten) gesellschaftlichen Gruppen zugeordnet werden, beschrieben. Diesem gehen psychologische Dynamiken der Stereotypisierung sowie historisch komplexe soziale Prozesse und Strukturen der Differenzierung und Hierarchisierung voran. Aufgrund sozialer, politischer und wissenschaftlicher Auseinandersetzungen ist Diskriminierung mittlerweile nicht nur als (Menschen-)Rechtsverletzung anerkannt, sondern permanent Gegenstand von Kontroversen über die (Il-)Legitimität von (Un-)Gleichbehandlung.
