The aim of this thesis is to give an overview of the population (family) development from its start in the fifties of the twentieth century until today and to suggest its possible focus in the future. In the theoretical part, the development of family and pro-population precaution in the former Czechoslovakia is described, including international context. The next thing that the theoretical part deals with is the development of the states support of families after the Velvet Revolution in the context of economical a political changes. The analytical part of this thesis deals with the development of fertility using detailed demographic data of sectional and cohort analysis. The conclusion of this paper outlines possible direction of family politics which could ease the life of families, for example in the context of the reconciliation between family and work life.

[pt] Eu desenvolvo um modelo de gerações sobrepostas com crescimento salarial ao longo do ciclo de vida (LCWP, por sua sigla em inglês), taxa de mortalidade dependente da idade, restrições de liquidez e rigidez nominal. O modelo é calibrado para capturar a transição demográfica dos EUA, estimativas de LCWP e outras características importantes da economia dos EUA durante o período 3;72-4239. O modelo é usado para examinar a relação entre dados demográficos e taxas de juros reais assim como os principais mecanismos de transmissão em jogo. Eu encontro que o rápido aumento da população em idade ativa entre 3;72 e 3;:2 contribuiu significativamente para o aumento das taxas de juros reais. A reversão desse processo, juntamente com o aumento da expectativa de vida, desencadeou um rápido declínio nas taxas de juros desde então. A heterogeneidade na propensão marginal a consumir entre os trabalhadores desempenha um papel importante na conexão desses movimentos de fertilidade e taxa de juros real. Num exercício adicional, devido à evidência de grandes erros de previsão da expectativa de vida, eu estendo o modelo com um processo de aprendizado sobre longevidade e encontro que ele pode aumentar significativamente a relevância de fatores demográficos na explicação dos movimentos reais das taxas de juros. Por fim, encontro que a falha dos bancos centrais em levar em conta a relação entre dados demográficos e taxas de juros pode gerar, devido a mudanças não monitoradas na taxa de juros natural, variações na taxa de inflação. / [en] I develop an overlapping generations model with life cycle wage profile (LCWP), age-dependent mortality rate, liquidity constraints, and nominal rigidities. The model is calibrated to capture US demographic transition, LCWP estimations, and other salient features of the US economy during 3;72-4239. The model is then used to examine the relationship between demographics and real interest rates and the main transmission mechanisms in play. I find that the rapid increase in the working age population from 3;72-3;:2s has significantly contributed to the rise of real interest rates. The reversion of this process together with the increase in life expectancy triggered a rapid decline in the interest rates ever since. The heterogeneity in the marginal propensity to consume among workers plays a major role in connecting these fertility and real interest rate movements. In an additional exercise, due to the evidence on large life expectancy forecast errors, I introduce a learning process about longevity and find that it can significantly a ugment t he r elevance o f d emographic f actors in explaining real interest rate movements. Finally, I find t hat t he central banks failure to recognize the relationship between demographics and interest rates can generate, due to unaccounted changes in the natural interest rate, inflation rate variations.

Die Dissertation fragt nach den Ursachen der spezifisch niedrigen Geburtenrate in Ost- und Westdeutschland, die seit Mitte der siebziger Jahre deutlich unter dem Reproduktionsniveau liegt. Theoretisch wird die Frage behandelt, inwiefern die gewandelte gesellschaftliche Stellung der Frau – insbesondere ihre höhere Bildungs- und Erwerbspartizipation – mit der Verbreitung geringer Kinderzahlen in Verbindung steht. Für die Analysen werden Scientific Use Files der Mikrozensen 1973 bis 2008 verwendet; diese repräsentieren jährlich 0,7 Prozent der deutschen Bevölkerung. So kann gezeigt werden, dass innerhalb vergleichbarer soziostruktureller Gruppen kaum ein Rückgang der Kinderzahlen auftrat. Differenziert nach Berufsbildungsabschluss, Erwerbstätigkeit und Finanzierung des Lebensunterhaltes zeigt sich, dass einzig Frauen ohne Berufsbildung sowie Frauen, die das Hausfraumodell leben, durchschnittlich 2,0 Kinder haben – dies ist sowohl im Jahr 1982 wie auch 2008 in Westdeutschland der Fall. Innerhalb der Gruppe der erwerbstätigen Frauen liegen die Kinderzahlen je Frau deutlich niedriger. Die Gruppe der Hausfrauen, die ihren überwiegenden Lebensunterhalt durch ihren Ehemann finanziert, hat sich in Westdeutschland im Zeitvergleich seit dem Jahr 1982 von 50 auf 25 Prozent der Frauen halbiert. Dieser strukturelle Wandel hin zu einer unabhängigen weiblichen Lebensführung führte in Westdeutschland zu Kinderzahlen weit unter dem Reproduktionsniveau. Die empirische Analyse zeigt, dass strukturtheoretische Modelle mit klassischen Variablen wie Familienstand, Erwerbsumfang und Einkommen die Varianz der Kinderzahl heute besser erklären können als noch in den achtziger Jahren. Im Fazit scheint ein gesellschaftliches „cultural lag“ auf – die gesellschaftliche Unterstützung zur Vereinbarkeit von Beruf und Familie ist offensichtlich zu gering, so dass die Emanzipation der Frau in Deutschland den negativen Effekt niedriger Geburtenraten hervorbringt. / The study focuses on the causes of low birth rates in eastern and western Germany, which has been below the level of reproduction since 1975. Theoretically the changing position of women in society is considered and the possible connections between higher female education, the spread of female employment and low fertility rates are discussed. The analysis is based upon scientific use files of the German micro census from 1973 up to 2008; the data represent annually 0.7 percent of the German population. It is shown, that there is no decline in fertility within similar socio structural subgroups. Controlled by educational/vocational training, employment and female income (financial independence) it is shown that only women with no vocational training and women with no own income have 2.0 children per women – this result is significant for Western Germany in 1982 as well as in 2008. Within the group of employed women the mean number of children is much lower. But the group of housewives declined in half from 50 to 25 percent between 1982 and 2008. This structural change toward female independent lifestyle leads to a very low birth rate in Germany. The empirical analysis shows that classical models using structural variables like family status, employment and income are able to explain a considerable higher variance of birth rates today. Summing up there appears to be a “cultural lag”: women get emancipated, but the public support and the compatibility of work and family stays low, as well as the birth rates of employed women led to low overall birth rates.

在台灣經歷少子化而後,國小超額老師問題相形嚴重. 故本論文以個案研究方式探討中型學校士東國小的資深與資淺教師為例,就學校歷史文化,課程設計,領導風格,及學校效能方面來探討教師在教職生涯滿意度與家長對教師之期望. / Since the phenomenon of low fertility rate emergent in Taiwan, the teacher of the primary education suffered and gradually caused the sever problem of the surplus elementary school teacher. Hence, the Shih-Tung elementary, a medium size school, is the scale aligned with optimal scale for government to borrow the experience. The thesis applied a case study method of in-depth interview for related party of teachers and parents of Shih-Tung Elementary School. Initially from retrieving the education core both from definition and ancient wisdom testing the true meaning for the primary education. It is discussed from the culture of the school, the belief of an organization, which is the symbol of pine, big pencil and eraser under persistent learning, preceding that, from the culture to the curriculum design in terms of characteristic of the school, the charm of the school which made less decline of the student enrollment. Moreover, from the leadership style to verify how it formed the consensus and the acceptance form the teachers, which later on lead the effectiveness of the school. Further, it is focused on the organizational behavior analysis applying the Hierarchy of Needs Theory and Motivator-Hygiene Theory to analyze the satisfaction factors of the teachers in the school. The main parts for the central idea are focused on the teachers’ attitude in relation with the satisfaction factors in the case school, in words, the organizational behavior of the case school. Hence, the discussions are brought under school culture and curriculum design, leadership style and school effectiveness, teachers’ working satisfaction and inspiration, parents’ expectation. Consequently, the result and suggestions are made for the 2 parts: one for the school, and the other for the government under the transition of the era. The suggestions are made for the school as to keep the culture and inheritance of the senior to the junior teacher as legacy, and improving the environment for more efficient purpose of using and curriculum design under innovated way under long history. And utilize the human resource of unmarried woman, and build a communicative talk relationship with the parents since the mutual understanding of both parties are changing from authorities to cooperative and increasing junior teachers in the near future.

Neolithic dispersal in Europe has been alternatively explained through spread of farmers (migrationist position) or by adoption of farming by Mesolithic foragers (indigenist position). Mixed explanations have considered a combination of both processes. Neolithic dispersal in Central Europe was traditionally viewed as migrationist process. It was believed that farmers colonized the area and replaced indigenous foragers. During the last decade, authors have adhered to integrationist view as they have observed the continuity between Mesolithic and Neolithic technologies. Interestingly, the most recent genetic analyses again invoked the idea of colonization. Surprisingly, little attention has been paid to demographic modeling. The farming quickly spread in Central Europe between 5 600 and 5 400 calBC. Assuming colonization, Neolithic dispersal in Central Europe would have to be associated with high fertility rate of farmers. Our goal was to test whether the fertility rate of farmers was high enough to allow them to colonize Central Europe without admixture with local foragers. We produced four stochastic models of population dynamics of farmers during their colonization in Central Europe. The principle of Model 1-3 is based on methods of population projections. Model 4 stems from the wave of advance...

目前超低生育率現象，已對整體社會的走向、國家經濟的發展、生活思維的方式等都產生了相當大的影響。換言之，生育不僅是婦女本身的問題，它與國際社會的動態、經濟的全球化、企業的國際化、現代的子女教育、社會的性別教育、老年人的護理等都有著相當緊密的關係。因此，本研究的主要目的，在於探討臺灣各縣市房地產價格對生育率的影響，並瞭解臺灣生育率持續下降的癥結所在，找出可能影響生育率下降的主要因素加以分析。 本文利用臺灣23個縣市別的追蹤資料，涵蓋期間為2000年至2008年，採雙因子固定效果模型進行實證分析。估計結果發現，在控制其他變數不變之下，在生育率遞延二期時，臺灣各縣市平均地價對生育率為負影響，且在生育率遞延三期時更為顯著，兩者之間的資源排擠效果更為強大。而其他影響臺灣生育率的主要因素，如：各縣市農業人口比例、各縣市粗結婚率、與外國人結婚人數比例皆呈顯著正影響；臺灣各縣市平均地價、原住民人數比例及婦女勞動參與率皆呈顯著負影響。 依本研究結果顯示，房地產價格是影響臺灣生育率相當重要的因素，政府應需高度正視此問題並有所作為。建議未來政府在訂定國家發展政策時，除需研擬更多提升生育率的策略，如：降低父母生育子女的機會成本、改善學前幼托體系，以及加強減輕家庭育兒壓力的宣導工作等，並可增加控制「臺灣房地產價格」及避免房價炒作之策略，以促進國家永續發展及增強國際競爭力。 / The current low fertility rate has been a great impact on our entire social trend, the development of national economy, and the way we think. That is, fertility is not only women’s consideration, but also an issue connected closely to international society, economical globalization, internationalization of business, children education, sex education, and nursing care of the elders. As a result, the main purpose of this paper lies on the effect of average land price on fertility rate in Taiwan. This article uses the panel data of the 23 counties and cities of Taiwan from 2000 to 2008, and does the evidence-based analysis by two-factor fixed-effects model. We found that the average land price has conspicuously positive effect on the fertility rate in Taiwan. While other main factors affect the fertility rate in Taiwan such as the proportion of farm-workers, crude marriage rate, and the proportion of marriage with the foreigners have conspicuously positive effects on it; on the other hand, female labor force participation and the proportion of aborigine have conspicuously negative effects on it. According to our study, average land price is the most important factor which affects the fertility rate in Taiwan, and the government should face the problem and do something to it. When making policy, it is suggested the government may take into consideration of how to control the housing price in Taiwan and avoid housing price speculation.

臺灣婦女生育率下降快速，近年來屢創新低，堪稱全球生育率最低的國家，總生育率自民國89年1.68、降為民國98年1.03，民國99年甚至降至0.90以下，提升生育率成為政府施政的重要課題。因為資料限制，生育率大多以總生育率(Total Fertility Rate)表示，而非較能反映婦女一生生育總數的世代完成生育率(Completed Cohort Fertility Rate)。這兩者間存有不少差異，以生育率下降的臺灣為例，總生育率會因生育時機遞延而低估世代生育率，以總生育率詮釋生育率可能有瑕疵。有鑒於此，本文以比較「世代」及「年代」兩者的差異，以生育率及死亡率為研究對象，探討較適宜描述臺灣特性的模型。 由於世代生育率會有資料不足的問題，本文使用外推法(Extrapolation)補足年齡較高（如35歲以上）的婦女生育率，並以四種模型估計年代生育率與世代生育率，包括Gamma模型、Gompertz模型、主成份分析(Principle Component Analysis)與單一年齡組個別估計法，希望找出適合預測臺灣世代完成生育率的模型。除了台灣資料，也用日本、法國與美國的世代生育率資料，比較各國世代生育率模型的異同。另外，本文也以世代及年代兩種觀點，類似生育率的探討方式，比較常用死亡率模型的優劣。 不論是生育率或是死亡率資料，配適模型結果皆以世代資料可得到較好的估計結果，生育率以單一年齡組個別估計法為最佳的模型，死亡率則以Gamma模型、主成份分析、單一年齡組個別估計法為較佳的模型。 / Taiwan’s fertility rates have been declining radically in recent years, much faster than most countries in the world. For example, the total fertility rate (TFR) is 1.68 in 2000, 1.03 in 2009, and even reduces to 0.90 in 2010. Therefore, one of the top priorities for Taiwan government policies is to enhance the willingness of having children. Due to the data availability, the TFR is used more often, although the completed cohort fertility rate (CFR) is a more reasonable measurement. However, previous studies showed that the TFR is likely to be influenced by the deferring (i.e., tempo effect) of childbearing and produces misleading results. In order to measure the effect of deferring childbearing, this study focuses on exploring the difference of measures in the view of cohort and period (especially the CFR vs. TFR) and evaluates which fertility and mortality model is more appropriate for Taiwan. Because there are fewer complete cohort fertility data, we use extrapolation to make up the higher age-group fertility data (such as aged 35 and above). We consider four fertility models in this study, including Gamma model, Gompertz model, principal component analysis, and individual group estimation. We use the data from Taiwan, Japan, France and United State data to evaluate these fertility models. The results indicate that the parametric models (Gamma and Gompertz) have the worst performance, probably due to the rapid change of fertility behaviors. In addition, similar to evaluating the fertility models, we compare the performance of frequently used mortality models using the cohort and period mortality data. The result shows that using cohort data to estimate fertility and mortality is better than period data. Also individual group estimation is the best model to fit fertility; the better models to fit mortality are Gamma model, principle component analysis and individual group estimation.

<p>The purpose of this research is to study the effect of different demographic and socio economic factors on the contraceptive use among currently married women of age 15-49 in the two regions of Ethiopia, Amhara (17,214,056) and Oromiya (27,158,471). Data are obtained from the 2005 Ethiopian Demographic and Health Survey (EDHS).

本文的主要研究目的，在於將文化因素（即龍年與虎年效果）納入生育行為的考量，以重新審視台灣生育率與婦女教育程度之間的Granger因果關係。利用台灣1952年至1994年資料進行實證的Cheng and Nwachukwu（1997）及Cheng（1999），其結論指出台灣教育程度與生育率之Granger因果關係並不顯著。本文將以該文章之實證模型為基礎，並加入代表龍年效應與虎年效應的虛擬變數以建立本文模型。 首先根據Cheng（1999）的資料與變數，利用台灣1952年至2005年之年資料，建立一個包含粗出生率、教育程度大專以上的比例、女性勞動參與率、與實質經濟成長率等四個內生變數，以及代表龍虎年效應的兩個虛擬變數之VAR模型。並以Toda and Yamamoto（1995）提出的Granger因果關係檢定，檢定台灣教育程度與生育率之間的因果關係。隨後，為增進估計的有效性，本文利用台灣地區1978年至2005年的季資料，共112個樣本進行實證研究。變數定義方面，將粗出生率替換為一般生育率，教育程度大專以上的比例替換為育齡婦女大專以上的比例。並根據上述建立之VAR模型，進行Granger因果關係檢定。 經由本文的實證研究發現，將龍年效果與虎年效果納入考量後，台灣婦女教育程度的提昇會Granger影響生育率的下降。亦即台灣婦女教育程度日益提升，是解釋生育率下降的重要因素，此結果與Cheng（1999）所提出的結果並不一致。此外，龍年與虎年對台灣的生育率分別有顯著正向與負向的影響。 / This paper tries to revisit the null hypothesis of Granger no-causality between female education and fertility rate in Taiwan, by considering the culture factors captured by Dragon and Tiger Years which might influences the fertility behavior. In addition, this study compares the primary finding with the result proposed by Cheng and Nwachukwu (1997) and Cheng (1999) which are that female education does not affect fertility rate in Taiwan. According to Cheng (1999), official time series yearly data from 1952 to 2005 provided by Taiwan government are used first, and quarterly data from 1978 to 2005 are required to improve the efficiency. This study models a 4-Variables VAR and applies Granger no-causality test proposed by Toda and Yamamoto (1995). The primary finding of this study is that there is a negative causality from female education to fertility rate in Taiwan, which is inconsistent with conclusions in Cheng (1999). In addition, culture factors do play a very important role in fertility behavior in Taiwan.
