Price Discrimination in College Tuition: An Empirical Case Study
No full textThis paper looks empirically at the financial aid award practices at a small, Midwestern, private university. By awarding more financial aid, colleges and universities effectively price discriminate; that is, they charge some students more than others. The results indicate that students with better high school records and test scores and with more financial need are given more aid. Nonwhite students also receive considerably higher aid. While these results can not be generalized, this analysis should be easy to replicate at other colleges
Communication Preference Assessment for Current Users of An Augmentative and Alternative Communication System
Get PDFWe replicated the findings of van der Meer et. al., (2012) to examine the acquisition of manual signs, picture exchange, and speech-generating devices. A nonconcurrent multiple-baseline design across participants combined with an alternating treatment design across Augmentative and Alternative Communication (AAC) modalities was implemented to assess the intervention. Communication preference was evaluated at three stages: pre-baseline, baseline, and throughout the intervention. During the intervention, all three participants met mastery criteria for each communication method and exhibited a preference for the speech-generating device. These results build upon previous studies by demonstrating the differential acquisition of three commonly used alternative communication modalities. Moreover, the findings suggest that children who are currently communicating with an AAC device may show a preference for a modality with which they have less history and lower skill proficiency. These results emphasize the importance of considering the child’s preference for manual sign, picture exchange, and speech-generating devices when implementing AAC interventions. Additionally, the present results further suggest the need for implementing continuous evaluation of a child’s communication preference to optimize their continued use of an AAC device
What Causes Democratic Backsliding in Latin America? A Comparative Case Study of Brazil, Chile, El Salvador, and Costa Rica
No full textThis study examines the causes of democratic backsliding in Latin America, comparing Brazil, Chile, El Salvador, and Costa Rica. Events like the January 8th, 2023 riot in Brazil and the use of intimidation tactics by President Bukele in El Salvador demonstrate the erosion that these two countries have faced. On the other hand, Chile and Costa Rica have maintained stable democracies. This study aims to understand what caused these countries’ different paths by examining the levels of political polarization, party deterioration, citizen dissatisfaction, and the presence of populist leaders. Overall, it was found that polarization and party deterioration increase the likelihood of democratic backsliding. Having a populist leader in power can also exacerbate the backsliding
What We Should (Not) Teach Students About Interest Rate Determination
No full textThere are two general approaches to interest rate determination--Liquidity Preference and Loanable Funds. The standard textbook treatment usually presents these two approaches as if they were two ways of doing the same thing. Textbook authors then switch back and forth between the two approaches depending on which seems better suited for the problem at hand. We argue in this paper that the choice between these two approaches does matter. You simply can’t have it both ways—either the interest rate is determined in the money market or in the loanable funds market, but not both
