Ringvorlesung im Frühjahrssemester 2021

Im Rahmen der von der Fach­schaft VWL organisierten Ringvorlesung des Frühjahrssemesters 2021 widmen sich internationale Referenten dem Themenfeld „Economics, Love, and Sexuality“ aus unterschiedlichen, dabei stets volkswirtschaft­lich geprägten Perspektiven. Die Veranstaltungen finden zu unterschiedlichen Zeiten online statt (Vorträge, die aufgrund der Zeitverschiebung am Vormittag stattfinden, werden aufgezeichnet und im Ilias-Kurs der Fach­schaft für eine begrenzte Zeit verfügbar gemacht). Das gilt für die erste und die letzte Ringvorlesung dieses Semesters. Nähere Informationen finden Sie weiter unten. Studierende aller Fakultäten sowie externe Gäste sind zu allen Veranstaltungen herzlich eingeladen.

Prof. Gigi Foster, Ph.D.(University of New South Wales, Australien):
“Are we Addicted to Love? A Parsimonious Economic Model of Love“
(Journal of Economic Behavior & Organization, September 2019)

Abstract:

Love is chronically under-emphasised in economics as a core source of human motivation. As it underpins our allocation of scarce resources including effort, time, and money, love is a viable target of serious economic analysis, but economists have generally provided only shallow and reductionist models of it. In this talk, one of the world's leading experts on modelling love from an economic standpoint will walk through the rationale, approach, models, and implications of her research on love with multiple co-authors. Research drawn on in the talk will include Are we Addicted to Love? (JEBO 2019), Is It Rational to Be In Love? (Edward Elgar 2017), and An Economic Theory of Greed, Love, Groups, and Networks (Cambridge University Press 2013).

Prof. Matthew Quaife, Ph.D.(London School of Hygiene and Tropical Medicine):
“Sex, risk, and preferences: Using stated preference data to model behaviour in HIV prevention“

Abstract:

Pre‐exposure prophylaxis (PrEP) to prevent HIV enables female sex workers (FSWs) to protect themselves from HIV without relying on clients using condoms. Yet, because PrEP reduces HIV risk, financial incentives to not use condoms may lead to risk compensation: reductions in condom use and/or increases in commercial sex, and may reduce the price of unprotected sex.

We integrated market forces into a dynamic HIV transmission model to assess how risk compensation could change the impact of PrEP among FSWs and clients. We parameterise how sexual behavior may change with PrEP use among FSWs using stated preference data combined with economic theory. Our projections suggest the impact of PrEP is sensitive to risk compensatory behaviors driven by changes in the economics of sex work. Condom substitution could reduce the impact of PrEP on HIV incidence by 55%, while increases in the frequency of commercial sex to co­unter decreases in the price charged for unprotected sex among PrEP users could entirely mitigate the impact of PrEP. Accounting for competition between PrEP users and nonusers exacerbates this further.

Intervention studies need to determine how HIV prevention products may change the economics of sex work and provision of unprotected sex to enable a better understanding of their impact.

Matthew Quaife is Assistant Professor in Health Economics at London School of Hygiene and Tropical Medicine, where he previously obtained his Ph.D. in Health Economics. He specializes in the prevention of infectious diseases, working at the interface of mathematical modelling and health economics. He faces the challenge of representing complex human behaviors in models and understanding how to encourage equitable and efficient health. His work mainly focuses on HIV and TB – two preventable and treatable diseases which remain two of the world’s biggest killers.

Prof. Erik Plug, Ph.D.(University of Amsterdam):
“Sexual Orientation, Competitiveness, and Income“
(Journal of Economic Behavior & Organization, July 2018)

Abstract:

Do gays earn less than other men because they are less competitive? Do lesbians earn more than other women because they are more competitive? To answer these questions, we conduct an experiment on a Dutch online survey panel to measure the competitive preferences of gay, lesbian and straight panel members. We find that gay men compete less than straight men, while lesbians compete as much as straight women. Linking our experimental measure of competitiveness to earnings and education data, we find that competitiveness predicts earnings and education levels and that differences in competitive preferences can partially explain the gay earnings penalty but not the lesbian premium.

“Technology and the Changing Family: A Unified Model of Marriage, Divorce, Educational Attainment and Married Female Labor-Force Participation“
(American Economic Journal: Macroeconomics, 2016)

Abstract:

Marriage has declined since 1960, with the drop being more significant for noncollege-educated individuals versus college-educated ones. Divorce has increased, more so for the noncollege-educated. Additionally, positive assortative mating has risen. Income inequality among households has also widened. A unified model of marriage, divorce, educational attainment, and married female labor-force participation is developed and estimated to fit the postwar US data. Two underlying driving forces are considered: technological progress in the household sector and shifts in the wage structure. The analysis emphasizes the joint role that educational attainment, married female labor-force participation, and marital structure play in determining income inequality.

Referent:

Cezar Santos is a Research Economist at the Bank of Portugal and Associate Professor of Economics at the Getulio Vargas Foundation in São Paulo, Brazil from where he also holds a M.Sc. He obtained his M.A. and his Ph.D. in Economics both at the University of Pennsylvania. Most of his published work focusses on quantitative Investigations into families and relations­hips, but his research also shows great interest in economic development and ongoing challenges for society.

Prof. Soohyung Lee, Ph.D.(Seoul National University, Südkorea):
“Propose with a Rose? Signaling in Internet Dating Markets“
(Experimental Economics, 2015)

Abstract:

A growing number of papers theoretically study the effects of introducing a preference signaling mechanism. However, the empirical literature has had difficulty proving a basic tenet, namely that an agent has more success when the agent uses a signal. This paper provides evidence based on a field experiment in an online dating market. Participants are randomly endowed with two or eight “virtual roses” that a participant can use for free to signal special interest when asking for a date. Our results show that, by sending a rose, a person can substantially increase the chance of the offer being accepted, and this positive effect is neither because the rose attracts attention from recipients nor because the rose is associated with unobserved quality. Furthermore, we find evidence that roses increase the total number of dates, instead of crowding out offers without roses attached. Despite the positive effect of sending roses, a substantial fraction of participants do not fully utilize their endowment of roses and even those who exhaust their endowment on average do not properly use their roses to maximize their dating success.
