Discrete Clock Auctions: An Experimental Study
Full text linkWe analyze the implications of different pricing rules in discrete clock auctions. The two most common pricing rules are highest-rejected bid (HRB) and lowest-accepted bid (LAB). Under HRB, the winners pay the lowest price that clears the market; under LAB, the winners pay the highest price that clears the market. Both the HRB and LAB auctions maximize revenues and are fully efficient in our setting. Our experimental results indicate that the LAB auction achieves higher revenues. This also is the case in a version of the clock auction with provisional winners. This revenue result may explain the frequent use of LAB pricing. On the other hand, HRB is successful in eliciting true values of the bidders both theoretically and experimentally.Auctions, clock auctions, spectrum auctions, experimental economics, behavioral economics, market design
An Analysis of the Effects of Poverty on Cognitive Status Among Middle-Aged and Older Adults in China: Exploring the Moderating Effects
No full textThe present study examines whether living in poverty influences cognitive status and whether sociodemographic and lifestyle factors moderate this relationship among middle-aged and older Chinese. Five outcomes were examined including three measures of fluid intelligence capturing memory and quantitative reasoning ability and two measures of crystallized intelligence reflecting acquired math and vocabulary skills. The fluid intelligence measures were only collected in the 2012 and 2016 China Family Panel Study (CFPS) waves and analyzed in a sample 9,420 individuals aged 45 and older and 18,840 observations (two repeated measures). The fluid intelligence measures were only collected in the 2012 and 2016 CFPS waves and analyzed in a sample 9,379 individuals aged 45 and older and 18,758 observations (two repeated measures). The key predictor was poverty defined by two different ways including 1.5 per day. The key moderators included age, gender, social engagement, and physical activity. Both fixed effects modeling and random effects modeling were performed. The results showed different patterns using different analytical methods and poverty definitions, suggesting the poverty effects on cognitive status are sensitive to analytical approach. The findings from fixed effects modeling suggested no poverty effects but those from random effects models showed significant and negative effects of poverty on all five outcomes. In addition, the random effects models documented that the poverty effects on short-term and long-term memory were less detrimental for those active in social engagement. No moderating effects of age, gender, and physical activity were found. As side findings, remarkably consistent and beneficial effects on cognitive status of education, good sleep quality, and active social engagement were found.
PILLS, POLICY, PROVIDERS: ANALYZING THE IMPACTS OF STATE-LEVEL ACA MEDICAID EXPANSIONS ON COUNTY-LEVEL OPIOID PRESCRIBING RATES
No full textState Medicaid expansions under the Affordable Care Act have attracted controversy for their purported role in worsening the nation's opioid epidemic. There is a perception in some political spheres that the expansions have increased the risk for more people to become addicted by increasing access to prescription opioids or have created significant opportunities to abuse and profit from the Medicaid system by flooding illegal drug markets with legally obtained prescription opioids. On the other hand, advocates of Medicaid point to the fact that the program provides beneficiaries with access to essential health services, including medication-assisted treatments that aid in treating opioid addiction, as evidence that the Medicaid expansions are actually helping to stem the flow of opioid-related deaths. This study employs a quasi-experimental difference-in-difference technique to study the impact of six state-level Medicaid expansions on country-level opioid prescribing rates, exploiting variation variation in expansion status across state borders. This thesis contributes evidence the state-level ACA Medicaid expansions in January of 2014 did not significantly increase opioid prescribing rates on the county level. This reduces worries that Medicaid expansion would further contribute to the opioid epidemic by increasing access to addictive gateway prescription drugs. Policymakers desiring to reduce opioid addiction by helping at-risk patients receive medication-assisted treatment should consider expanding Medicaid in their states, as well as substantially increasing funding for the program
Explaining Change and Stability in the U.S. Federal Budget: the Effects of Political and Economic Factors on Appropriations
No full textThis study examines which political and economic factors influence the United States annual budget. As there is a gap in the scholarship surrounding the interaction of environmental variables and their effect on the allocation of funds across programs and agencies, this thesis adds a novel contribution to the literature. First, this paper utilizes a data set on the federal budget for fiscal years 1955 to 2002 and contains financial information on over 1,800 individual government programs. By leveraging this dataset, I produce a distribution of year-to-year changes in the budget during the sample period and determine patterns in the volatility of federal spending patterns over the past half century at different levels of aggregation. Second, by using an OLS model, this paper explores the relationship between the political and economic variables and changes in the budget over time. Particularly, the results support the conclusion that other than the constraining nature of the deficit on congressional spending decisions, changes to the budget have largely been a result of endogenous—rather than exogenous—forces at all levels of aggregation
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
State Ownership in China: An Equity Network Perspective
No full textThis chapter introduces a novel measure of state-owned enterprises (SOEs) in China using an equity network perspective. Leveraging a comprehensive firm registration dataset from SAIC, the authors construct dynamic ownership trees that trace direct and indirect government control from central, provincial, and city levels. By setting various ownership thresholds (100 percent, 50 percent, 30 percent, 10 percent, and >0 percent), the new measure reveals a substantially larger pool of SOEs than traditional self-reported indicators from the Annual Industrial Survey. The analysis uncovers systematic misreporting issues in existing definitions and demonstrates trends in state ownership, including a shift toward decentralization and increased indirect control over time. The findings offer fresh insights into the structure of China’s state capitalism and the evolving role of government in the economy, laying a robust foundation for future research on the economic impact of state ownership in China
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
