摘要： Single mothers by choice (SMCs) have been defined as single women who proactively became SMCs through adoption, surrogacy, donor insemination, or conception from a known donor or sexual partner (Morse, 2007). The SMC demographics typically are women in their 30s or older, highly educated, financially stable, and White (LeBlanc, 2001). Existing literature on SMCs lacks diversity across different ethnic groups. Therefore, to address this gap in the literature, this study was designed to explore Women of Color’s decision-making process becoming an SMC and how they would describe their experiences as SMCs. The research questions are: How will Women of Color describe their decision-making process in becoming a single mother by choice (SMC)? How will Women of Color describe their experiences as a single mother by choice? A general qualitative approach utilizing semi-structured interviews was employed to capture the narratives of Women of Color who identified as SMCs. The data analysis for this study followed the six phases developed by Braun and Clarke (2006), an inductive procedure with a semantic process dedicated to thematic coherence. Seven women participated in this study and were recruited through *** and ***. Two participants became single mothers by choice through direct insemination and five became single mothers by choice situationally. Five themes and nine sub-themes were created from the interviews’ analysis, as they were related to the two primary research questions. When considering Research Question 1, one theme, Decision-Making Process and six sub-themes (social situation to choice, assessing resources/capacities for SMC, letting go: deciding to mother, supportive extended family, exposed to successful single mothering, wanting to mother: not necessarily partner) were identified. As it related to Research Question 2, four themes and three sub-themes were created: Culture Informs Parenting (culture of connectedness, promotin

摘要： 《宏观经济学》作为经济管理类专业的专业基础课,以往采用的传统"授受"教学模式,伴生出学生思维活动不积极等问题。"对分课堂"作为一种新型的课堂教学模式,有益于激发学生的学习主动性和提高学习效率。将"对分课堂"植入《宏观经济学》教学中,可通过合理选择使用次数及类型,有效安排对分课堂课后作业,推动课程教学效果的提升。

摘要： In this dissertation, I study how firm dynamics affect business cycles and monetary policy. In Chapter 1, I study the effects of pro-cyclical entry on aggregate employment in a general equilibrium framework. The key features of the model are that firms’ markups increase with market share and adjustment costs prevent employment from reallocating across firms. In response to a decline in entry, incumbent firms’ market shares increase and they increase markups and reduce employment. To quantify this mechanism in the model, I study the relationship between variable inputs and revenues in panel data on large firms. Viewed through the lens of my model, my estimates imply that for large firms the within-firm elasticity of the markup to relative sales is 35%. I then study shocks to entry in a model that is calibrated to be consistent with this elasticity, finding that a fall in entry can lead to a significant contraction in employment. A shock to entry that replicates the decline in the number of businesses during the Great Recession generates a prolonged 3 percent fall in employment in the model. Finally, I show that the increasing correlation between market shares and markups over the last 30 years implies that the effect of entry on the business cycle is becoming stronger with time. In Chapter 2, I study monetary non-neutrality in a frictional product market. The model incorporates the idea that goods are in general not monopolistically supplied; rather, consumers can purchase the same good from many outlets. I find that incorporating this feature into a menu cost model increases the degree of monetary non-neutrality. The reason is that competition between stores makes their prices complementary, so that firms face strong penalties for setting prices far away from their competitors. It makes pass-through of cost shocks heterogeneous and decreases the strength of the selection effect. I also use the model to study cyclical changes in monetary non-neutrality. I find that t

摘要： 一直以来,宏观经济学都是高等院校经济管理专业学生的一门必修课程。然而,在很多高校,尤其是民办高校,该课程似乎成为很多学生的噩梦:不仅学习效率低,而且学习效果差。同时,宏观经济学教学环节也存在种种问题。基于上述困境,对宏观经济学进行教学改革刻不容缓,这要求教师重新思考授课方式,改革课程考核方式,将学生拉回课堂,提高他们的学习积极性,变被动学习为主动学习。这将有利于培养学生的经济学思维,也为其学好其他课程打下基础。

摘要： 中国证券市场交易额从1994年的183亿迅速增长至2020年的20万亿,中国证券市场在近二十年取得了较为瞩目的发展,但其发展过程中也存在着许多中国证券市场特有的异象,最具代表性的是中国证券市场的上市企业IPO首日破发较少,即IPO首日抑价率较高的现象。目前中国学术界对IPO破发的研究已经较为普遍,论文主要研究货币供应量对IPO破发的影响,目前这个研究相对较少,论文的研究将有利于政府、广大投资者进一步理解货币供应量对IPO破发的影响机制。本文基于行为经济学、宏观经济学理论研究货币供应量对IPO破发的影响,以及货币供应量对IPO破发的影响机制。针对该课题研究,论文采用了文献研究法及实证研究方法相结合进行相关分析。首先,在文献研究部分,通过回顾前人关于货币政策、投资者情绪及IPO破发等相关文献,了解有关问题的研究成果,帮助变量指标选用的准确性。其次,在实证部分,被解释变量中的货币供应量选取货币供应量(M2)作为代理指标,机构投资者情绪则选取网下累计超额认购倍数均值作为代理指标。论文将解释变量中的IPO破发率分为短期破发率以及长期破发率,并进一步建立货币供应量、机构投资者情绪与IPO破发率的相关假设及因果关系模型,通过回归分析进行验证假设。研究结论显示:1)货币供应量(M2)与IPO短期破发率具有显著的负相关关系,货币供应量(M2)越大,IPO短期破发率越低。2)货币供应量(M2)与IPO长期破发率具有显著的负相关关系,货币供应量(M2)越大,IPO长期破发率越低。3)货币供应量(M2)越大,会正向激励机构投资者情绪,进而抑制短期的破发率。4)机构投资者情绪并非是货币供应量(M2)影响长期破发率的一条潜在传导渠道。

摘要： This dissertation provides new analytical frameworks of network and behavioral theories in order to answer real-world economic questions where more simplified traditional models have struggled to explain. In Chapter 1, I provide a theory of international portfolio investments where international investors have heterogeneous consumption preferences and goods are produced in a global production network. While traditional two-country models can only explain the asset allocation between domestic and foreign assets, my theory explains also the composition of external investments, i.e. how investors should optimally allocate their investments between multiple foreign destinations. I solve in closed form for the optimal equity and bond portfolio investments in a workhorse multi-country real business cycle model and show in Chapter 2 that the network-theory implied portfolio has empirical explanatory power for the actual portfolio holding patterns observed in the data. In Chapter 3, I provide a behavioral-based explanation of two recent macroeconomic puzzles: (i) the anchoring of inflation and (ii) the flattening of the Phillips Curve. In particular, I introduce endogenous behavioral inattention into the standard New Keynesian model and derive a new Phillips Curve, called the Behavioral-Attention Phillips Curve (BAPC). The BAPC has both an output-gap slope and inflation-expectation slope that decline with inflation uncertainty in the economy. Using data from the Michigan Surveys of Consumers, I estimate the BAPC and show that it provides a better in-sample and out-of-sample fit of the US inflation dynamics since 1978 than traditional versions.

摘要： Essay 1: Exchange Rate Dynamics and Global Monetary Policy Spillovers: Time-Varying Dynamic Causal Effects. We propose a novel econometric approach to estimate time-varying dynamic causal effects of structural shocks using external instruments in a factor-augmented-VAR model. Using the Bayesian MCMC estimation method we estimate a model consisting of output, inflation rates, interest rates, and exchange rates for the United States, Canada, Germany, Japan, and the United Kingdom. We find uniformly strong evidence over time that the exchange rate overshoots in response to an exogenous monetary policy shock. Furthermore, we find that the monetary policy shock played a significant role in the exchange rate dynamics, and its contributions were particularly large during the 2008-2009 financial crisis. Essay2: Commodity Return Comovement, Exchange Rate, and Uncertainty Shock. This paper investigates how the uncertainty shock affects the commodity return empirically, using a time-varying parameter dynamic factor model with stochastic volatility (TVP-DFM-SV). We extract a common factor and eight sector-specific factors from 43 different commodity returns (Ma, Vivian, and Wohar, 2019). The common factor is interpreted as the combination of the shocks which only affects the commodity markets idiosyncratic through the general equilibrium (Alquist, Bhattarai and Coibion, 2019), and is orthogonal to the sector-specific factors and commodity-idiosyncratic factors. Then we show the time-varying impulse responses of the common factor and several relevant marco fundamentals to uncertainty shock identified by the external instrument variable (IV). We find that uncertainty shock decreases the commodity return through the common factor, and this effect is time-varying, specifically, during the recession it is stronger. Besides, the uncertainty shock could be a reason behind the negative relationship between commodity return and the strength of the US dollar. Essay3: A New Approach to Co
