The conditional spatial correlations between racial prejudice and racial disparities in the market for home loans
Many studies have shown the existence of disparities in loan denial rates between blacks and whites that cannot be accounted for by observable applicant characteristics. Examining the link between racial gaps in home loan denial rates and prejudicial attitudes toward blacks measured by questions in the General Social Survey
this article shows not only that blacks are more likely to be denied conventional home mortgages but that denial rates among blacks for these loans are also geographically correlated with racial prejudice
particularly among first-lien home purchase loans and loans from depository lenders. However
among Federal Housing Administration-insured loans guaranteed by the government in the event of borrower default
this study finds no evidence of a statistical relationship between racial prejudice and loan denials among black applicants. Results are consistent with taste-based discrimination by discriminatory lenders; however
one cannot rule out that statistical discrimination is at least partially driving the results.\n\n许多研究表明,黑人与白人的贷款拒绝率之间存在差异,这一差异无法用可观察的申请人特征来解释。本文研究住房贷款拒绝率的种族差距与一般社会调查中对黑人偏见态度之间的联系,不仅显示黑人更有可能被拒绝授予传统住房抵押贷款,而且对黑人的这些贷款拒绝率也与种族偏见在地理上相关,尤其是在首次留置权购房贷款和存款贷款人的贷款中。然而,在政府为借款人违约提供担保的联邦住房管理局保险贷款中,本研究未发现种族偏见与黑人申请人贷款受拒之间存在统计学关系。结果与歧视性贷款者基于口味的歧视一致;然而,人们不能排除统计学上的歧视至少部分推动了相关结果。
The conditional spatial correlations between racial prejudice and racial disparities in the market for home loans
Objective:\nThe Healthier Options for Public Schoolchildren (HOPS) intervention aimed simultaneously to change school policies regarding the nutritional content of school-provided meals
nutrition and healthy lifestyle curricula
and other school-based wellness activities. Researchers examined how HOPS affected students’ academic achievement
attendance and behaviour.\n\nDesign:\nLongitudinal study of 23
335 elementary-school students aged 4–16 years enlisted in kindergarten to grade 8 in the 2005–2006 school year and followed through until the 2008–2009 school year.\n\nSetting:\nHOPS was implemented in 11 Buffalo (New York) public elementary schools at the start of 2007–2008 school year and concluded in January 2009; 34 other district elementary schools were chosen for comparison.\n\nMethod:\nAdministrative records were obtained containing student demographics
mathematics and English test scores
and attendance and disciplinary records. A difference-in-differences approach was used to measure the HOPS intervention’s effect on mathematics and English test scores and the proportion of days present or not suspended. Significance was tested at 1% and 5% levels.\n\nResults:\nAnalysis comparing students in intervention and comparison schools revealed an increase in standardised mathematics test scores among all students (p < .05)
with particularly strong impacts on girls (p < .01)
African American and Hispanic students (p < .01) and economically advantaged students (p < .01). HOPS had an adverse impact on attendance and disciplinary referrals (p < .01)
although the effects were small.\n\nConclusion:\nWhen considering the implementation of a school-based wellness programme
administrators should consider its academic benefits. Research into the effectiveness of programmes such as HOPS at improving cognitive and non-cognitive outcomes of school-aged children is particularly relevant given recent US Department of Agriculture rollback of whole grain
sodium and milk requirements.

By using a data set of professional basketball players' free agent contracts from the National Basketball Association (NBA) between the 2001-2002 and 2007-2008 seasons
which has rich data on worker productivity
the author is able to identify the effect that changes in income tax rates have on the labor migration decisions of NBA free agents. After controlling for other observable characteristics of teams
cities
and states
the author finds that an increase in the marginal income tax rate faced by NBA basketball players that play for a given team leads to a decrease in the average skill of the NBA free agents that migrate to that team.
Tax Avoidance: How Income Tax Rates Affect the Labor Migration Decisions of NBA Free Agents
I seek to determine whether race is a factor in how black representatives vote in the United States House of Representatives; if so
this suggests electing more black representatives may improve the economic and political position of blacks if policy positions taken by black representatives on bills that fail to pass would provide tangible positive impacts to members of the black community if passed. Confounding the impact of legislator race
districts represented by blacks on average are quite different than those represented by whites. While past research on this topic uses linear regression techniques with undesirable properties
I improve on past research using matching techniques with more desirable properties. Utilizing a combination of Mahalanobis and propensity score matching
within-caliper matching
and exact matching using data from the 100th–113th Congress
I show black representatives are more likely to vote in agreement with the majority of the Congressional Black Caucus on all votes and on Leadership Conference on Civil and Human Rights
Americans for Democratic Action
and Congressional Quarterly key votes
indicating a substantive racial impact on roll-call voting.
Substantive Black Political Representation: Evidence from Matching Estimates in the United States House of Representatives
It is well known that the hiring rate of black head coaches in major college football is not representative of the number of student-athletes that are black. However
less obvious is the fact that black head coaches may be treated unfairly when decision-makers decide whether to retain or fire their institution’s current head coach. In this paper
I use a rich dataset of National Collegiate Athletic Associate football coaches from 1990 to 2012
containing measures of coaching performance and school expectations
as well as information on each coach’s race and whether he was fired or retained in each season. Using this data
I estimate a discrete-time hazard model of the probability that a head coach is fired
allowing the hazard rate of black head coaches and white head coaches to differ
and find that black head coaches are 5.28 percentage points more likely to be fired than their white counterparts. Additionally
I find that black head coaches are more likely to be fired in the initial 3 years of tenure
and again in their seventh and eighth years
but that the difference in the probability of release between black and white head coaches in the fourth through sixth years of tenure is small and statistically insignificant.
You’re Fired!: The Impact of Race on the Firing of Black Head Coaches in Major College Football
In the past few years there have been numerous high-profile shootings by police
with wide-spread speculation that a number of these incidents may have been either racially motivated or the result of an abuse of power by law enforcement. While past researchers have used community-level data to test theories of “racial or economic threat
” that police target violence at minorities or the poor to prevent redistributive criminal activity and maintain the existing order
or “reactive hypotheses” of policing
focused on the use of force to prevent violence against officers and other citizens
the majority of these studies are dated
rely on incomplete government data on justifiable police killings
and fail to consider predictors of police killings such as non-murder violent offense rates
property crime rates
or violence against police. However
recently many internet archives have collected more complete data on police killings
and I utilize one such source to estimate a negative binomial regression model at the metropolitan area level to test differing theories of the use of deadly force by police. In addition to finding that police-related fatalities are strongly correlated with murder rates
findings show substantial evidence that police-related fatalities are also strongly correlated with rates of aggravated assault
motor vehicle theft
and assault on officers
factors other studies have not considered. However
contrary to previous studies mostly considering justifiable killings I find little to no evidence in favor of the “racial or economic threat hypotheses” when examining the total number of police-related fatalities within a metropolitan area.

This study explores regional bias in Heisman voting from 1990–2016 using a negative binomial regression model with player-year fixed effects. Analysis confirms finalists receive higher vote tallies in home regions
on average. Additionally
results show regional vote tallies are decreasing in the fraction of other finalists in-region. Furthermore
evidence reveals finalists receive higher vote tallies for each game played against in-region teams and lower vote tallies for each game played by other finalists against in-region teams. Analysis is augmented by showing the recent increase in national television coverage of college football has been accompanied by a decline in regional bias.
The nature of regional bias in heisman voting
This paper explores the relationship between discrimination towards blacks and the black-white self-employment rate gap
and provides the first direct empirical evidence that discrimination negatively impacts black self-employment. As a proxy for discrimination
I construct a measure of prejudicial attitudes using responses from the 1993-2010 General Social Survey. After compiling an index of prejudicial attitudes
I estimate the relationship between self-employment and this index of prejudicial attitudes using the 2005-2009 American Community Survey. I find that an amount of prejudice equal to the difference in the least and most prejudiced census divisions increases the black-white self-employment rate gap by 24.2%-34.5%.
Does racial prejudice affect black entrepreneurship?: evidence exploiting spatial differences in prejudicial attitudes
Existing literature pertaining to discrimination in Brazil often uses education and income as measures of class
but seldom includes occupational prestige. However
occupation
an aspect of daily life and a socioeconomic indicator
may explain a large amount of variation in acknowledgement of skin color discrimination among blacks and browns in Brazil. In this study
we examine whether those in different occupations acknowledge skin color discrimination differently. Based on existing literature
the expectation was that individuals in high status occupations would be more likely to acknowledge skin color discrimination. However
to the contrary
our analysis of the 2010 Latin American Political Opinion Project survey
which utilizes an ordered logistic regression model with controls for education
expected labor market experience
gender
household income
skin color
location
and province
reveals blacks and browns in less prestigious occupations are more likely to report experiencing color discrimination
particularly among men. This study offers new insights about perceptions of color discrimination in Brazil by challenging the traditional idea that high status blacks and browns are more aware of color discrimination than those of lower status
and is important to research on race and ethnicity generally
bridging studies in sociology
Latin American studies
and African diaspora studies.

Objective: In this article
I test for evidence of own-race bias in voting for the Heisman Trophy.\n\nMethods: To study own-race bias in Heisman Trophy voting
I use individual vote data from Heisman voters from 2002-2012 and an ordered probit model with controls for player and team performance that flexibly allows votes be affected by a player’s race and racial match between player and voter.\n\nResults: Estimates show nonblack voters are more likely to vote for nonblack players in absolute terms and compared to black voters assuming homogenous voter preferences. Allowing preferences to vary by race
results show nonblack voters continue to be more likely to vote for nonblack players in absolute terms and are strongly suggestive of a larger relative bias in favor of nonblack players by nonblack voters as compared to black voters.\n\nConclusion: There is a racial component to Heisman Trophy voting and bias is large enough to affect official aggregate results. Racial bias may have affected the award’s winner in multiple Heisman races between 2002 and 2012.
