Three Essays In The Economics Of Disagreements: Incentives, Measurement And Persistence, Mustafa W. Alam

All Dissertations

This dissertation presents three chapters that contribute to the study of economic forces shaping disagreements in society.

In Chapter 1, I demonstrate that political polarization can intensify due to innovations in the information market even if a population's ideological distribution is fixed. Viewership-maximizing news firms cater to a diverse audience who assess source accuracy using noisy private signals that vary in precision and ideological bias. If better-informed consumers disproportionately migrate to newer platforms for news (e.g., the Internet), traditional media firms increase news slant to appeal more to less-informed partisans on both sides of the ideological spectrum. This leads to …

Public Preferences For Flood Warning Improvements: An Inferred Valuation Approach Addressing Social Desirability Bias, Katsuya Tanaka, Kazuhide Akaishi, Takashi Yokota

Center for Public Service Publications and Reports

Despite the crucial role of flood warning systems in mitigating disaster impacts, their economic value—particularly the value of specific attributes—remains poorly understood. This study evaluates public preferences and willingness to pay (WTP) for three flood warning attributes: advance notice, warning reliability, and geographical precision, using a choice experiment conducted in Tokyo's Koto 5 Wards. To address social desirability bias, the study employs both standard and inferred valuation methods, with the latter asking respondents to predict their neighbors' choices. The findings reveal that warning reliability is the most highly valued attribute, with an inferred WTP of ¥2,345 per household annually for …

Constitutional Futurisms, Jeremiah Chin

Articles

How do we reckon with the past? The Supreme Court’s recent embrace of originalism as a mode of constitutional analysis relies almost exclusively on a view of history and tradition that would bind us to an understanding of principles and ideals that legitimized the exclusion of minority voices. Cases such as New York State Pistol and Rifle Ass'n v. Bruen use flavors of originalism as a framework to define rights and governmental powers through their historical antecedents, but this broad standard of interpretation is notably absent in the Court’s recent discussions of histories and traditions of racism in the United …

Impact Of Non-Uniform Surface Temperature On The Apparent Radiative Properties Of Cavity Receivers, Ehsan Mofidipour, Matthew R. Jones, Brian D. Iverson

Faculty Publications

Radiative surface properties play a critical role in the design, analysis and optimization of solar–thermal systems. Cavity receivers increase the efficiency of solar–thermal energy systems through the cavity effect. The cavity effect refers to increased absorption of radiation due to multiple reflections within a cavity. Apparent radiative surface properties of a cavity characterize the effective interactions of radiation passing through an imaginary surface covering the cavity aperture. In this study, we investigate the extent to which the apparent emissivity of a cavity with a non-uniform surface temperature profile may be estimated using an isothermal enclosure model. A cylindrical cavity was …
