The paradox of grading systems

We distinguish between (i) voting systems in which voters can rank candidates and (ii) those in which they can grade candidates, using two or more grades. In approval voting, voters can assign two grades only—approve (1) or not approve (0)—to candidates. While two grades rule out a discrepancy between the average-grade winners, who receive the highest average grade, and the superior-grade winners, who receive more superior grades in pairwise comparisons (akin to Condorcet winners), more than two grades allow it. We call this discrepancy between the two kinds of winners the paradox of grading systems, which we illustrate with several examples and whose probability we estimate for sincere and strategic voters through a Monte Carlo simulation. We discuss the tradeoff between (i) allowing more than two grades, but risking the paradox, and (ii) precluding the paradox, but restricting voters to two grades.     

Missions Impossible: Prospects and Planning in American Higher Education

Most colleges and universities in the United States face serious questions about missions, money, and morale in the 21st century. Some recent excellent books are useful for showing divergent perspectives on these problems. To one extreme, an historian tends to see that lack of planning has been an unexpected, enduring positive force. To another extreme, a high profile state university president draws on innovations in structure to deal with changes in demographics and academic fields. This review essay provides a balanced exploration of the disparate approaches, leading to the conclusion that American higher education is in need of a substantive "New Deal" in purposes and policies.     

Neighborhood,Family, and Peer Factors Associated with Early Adolescent Smoking and Alcohol Use

There is broad agreement that neighborhood contexts are important for adolescent development, but there is less consensus about their association with adolescent smoking and alcohol use. Few studies have examined associations between neighborhood socioeconomic contexts and smoking and alcohol use while also accounting for differences in family and peer risk factors for substance use. Data drawn from the Seattle Social Development Project (N?=?808), a gender-balanced (female?=?49%), multiethnic, theory-driven longitudinal study originating in Seattle, WA, were used to estimate trajectories of smoking and alcohol use from 5th to 9th grade. Time-varying measures of neighborhood socioeconomic, family, and peer factors were associated with smoking and alcohol use at each wave after accounting for average growth in smoking and alcohol use over time and demographic differences. Results indicated that living in more socioeconomically disadvantaged neighborhoods, lower family income, lower family general functioning, more permissive family smoking environments, and affiliation with deviant peers were independently associated with increased smoking. Lower family functioning, more permissive family alcohol use environments, and deviant peers were independently associated with increased alcohol use. The effect of neighborhood disadvantage on smoking was mediated by family income and deviant peers while the effect of neighborhood disadvantage on alcohol use was mediated by deviant peers alone. Family functioning and family substance use did not mediate associations between neighborhood disadvantage and smoking or alcohol use. The results highlight the importance of neighborhood, family, and peer factors in early adolescent smoking and alcohol use. Future studies should examine the unique association of neighborhood disadvantage with adolescent smoking net of family socioeconomics, functioning, and substance use, as well as peer affiliations. Better understanding of the role of contextual factors in early adolescent smoking and alcohol use can help bolster efforts to prevent both short and long harms from substance use.     

Parental Control of the Time Preadolescents Spend on Social Media: Links with Preadolescents’ Social Media Appearance Comparisons and Mental Health

Time spent on social media and making online comparisons with others may influence users’ mental health. This study examined links between parental control over the time their child spends on social media, preadolescents’ time spent browsing social media, preadolescents’ appearance comparisons on social media, and preadolescents’ appearance satisfaction, depressive symptoms, and life satisfaction. Preadolescent social media users (N?=?284, 49.1% female; aged 10–12) and one of their parents completed online surveys. Preadolescents, whose parents reported greater control over their child’s time on social media, reported better mental health. This relationship was mediated by preadolescents spending less time browsing and making fewer appearance comparisons on social media. Parental control over time spent on social media may be associated with benefits for mental health among preadolescents.     

Constitutional political economy,democratic theory and institutional design

Democracy and constitutionalism are both central to the Western political tradition. And yet, constitutional restrictions are often perceived to be in tension with democratic commitments. I argue that the constitutional political economy approach developed by Nobel Laureate James Buchanan resolves the tension between constitutionalism and the values of democratic governance by shifting the analysis from a system-attributes perspective that focuses on the particular institutional properties of a political order to a system-legitimacy perspective that focuses on the manner in which political institutions gain democratic legitimacy. In so doing, the approach reveals that constitutionalism can be understood as a natural expression of democratic values.     

Introduction to welfare economics

We show that a transfer received by a minority of the population may be sustained by majority voting, however small the minority targeted may be, when the attribution of the transfer is seen as stochastic by voters. We build a simple model wherein voters differ in income and vote over a proportional tax whose proceeds are distributed lump-sum, and each voter has a probability of receiving the transfer that depends on his income. In progressive steps, we present intuitively appealing sufficient conditions on this probability function for the social program to be supported by majority voting. We also develop intuitive conditions for the emergence of the “paradox of redistribution”, whereby more focused targeting reduces the size of the transfer program chosen by the majority. We finally apply our framework to the French social housing program and obtain that our model is consistent with a majority of French voters supporting a positive size for that program.
