Dollars and Sex: How Economics Influences Sex and Love

Rate this book
There's a marketplace for sex and love, and you're in it. In Dollars and Sex , economist Marina Adshade converts economic theory into a sexy science by applying the principles of supply and demand and other market forces to matters of love and libido. As she does in her hugely popular blog of the same name, Adshade unlocks the mysteries behind our actions, thoughts, and preferences using engaging research, economic analysis, and humor. The end result is a fascinating look at just how central the interplay of libido, gender, love, power, and economic forces is to the most important choices we make in our lives. Ultimately she shows that every option, every decision, and every outcome in matters of sex and love is better understood through economics.

I love behavioral science/economics books. Adshade's approach is to temporarily suspend moral reasoning in order to better explore how incentives and transaction costs (not necessarily money) can interpret/predict aggregate human behavior.

For example, she explores how an increasing majority of women in college has created a male buyers' market for casual sex. Because females have more competition, their costs for sex increase, while the male costs drop. Perhaps counter-intuitively, she advises parents who worry about putting their daughters in a promiscuous environment to send them to male dominated colleges. While males introduce promiscuity, the daughter will have greater bargaining power when dating.

Adshade goes on to explore the behavior economics surrounding marriage, polygamy, online dating, STDs, etc. Good stuff.

I was interested and curious about this book until in the first chapter when it equates the thought and econonical risk analysis of a woman who was obviously date raped and left pregnant and had to get an abortion. They weigh/perceive her future choices and more cautious behaviour with drinking/partying and contextualize it as that she knows that it is a "mistake she cant afford to make again" not, oh, due to a fear of being assaulted again.

Here's your fact for the day: there is an inverted U-shaped relationship between penis length and economic growth. Countries that have the slowest economic growth appear both on the smallest and largest end of the penis size spectrum, while the countries that have the most average, middle-of-the-road penis length have fast-growing economies.

A good statistician will tell you that this is correlation and not causation, but this "Boner Curve" an interesting fact nonetheless. It is also one of the first things you learn when you open Marina Adshade's Dollars and Sex: How Economics Influences Sex and Love.

Dollars and Sex: How Economics Influences Sex and Love is an apt title for a book that looks at the economics of love and sex, and Adshade's collection of stories and examples that illustrate basic economic principles is a compelling way to teach the study of market behaviors. The book takes the seemingly-boring study of economics out of the classroom and into the bedroom, and then, most importantly, right back into the lecture hall. This is not strictly an academic treatise, nor is it a titillating tale of coitus; Dollars and Sex: How Economics Influences Sex and Love is a primer on the basic economic principles we all should know, but have always been too bored to learn.

***

Over the past year, at least two dozen people have told me that I should be an economist. At first, I took this as an insult—economics doesn't have the most exciting and thrilling of reputations—but I grew to love the sentiment. As an anthropologist, the decisions we make when we interact with others fascinates me; looking at the market drivers (and other such considerations) behind those decisions has become more and more appealing over the past few years.

My newfound fascination with economics has led me to perhaps be too liberal with my talk of opportunity cost, efficiency, supply and demand, externality, and sunk cost. When I lose myself in this kind of conversation (mostly with myself, and whomever is listening before they inevitably tune out), *L* often gives me a look that reminds me that not everyone is as enthusiastic about the economy as I may be. She indulges me in my pipe dreams of quitting my job to pursue a PhD in economics, dreams that are quickly dashed when I realize that, a) I can't afford to lose my income to go back to school right now, and b) my mathematics and statistics skills are dramatically under par for any kind of academic pursuit in anything but the liberal arts.

Books like Adshade's Dollars and Sex: How Economics Influences Sex and Love are then a perfect read for someone like me: they give me the semblance of academic rigor with the relatability of popular culture. While people may tune out if I talk about economics, everyone is always eager to talk about love and sex. A marriage (pun fully intended) of both topics satiates my appetite to go back to school, at least for now; while talking about elasticity might not be everyone's cup of tea, everyone's always eager to learn about the Boner Curve.

Dollars and Sex.

With a provocative title and cover, this book is not going to go unnoticed. The content within is gripping too, albeit for a different reason-- a scholastic one. Dollars and Sex looks at the institutions of sex, love, marriage, and dating through the lens of economics. Supported by research and data, Marina Adshade proposes simple economic theories to explain how we make choices in love.

The book is not for the romantic at heart--it reduces every choice to a calculation, albeit at a subconscious level. Our decisions to marry someone, have sex at a particular age, be faithful to a spouse, etc. all boil down to a cost analysis (How much do I have to lose because of the decision?).

But well, her theories mostly make sense.

The book is easy to read. The only con might be an excess of statistics. But well, this is an economist who is writing on every day economics. So what do we expect?

The Love Market: What You need to know about how we date, mate, marry
By Dr. Marina Adshade

Mix one part sex, love, marriage, another thousand parts statistics, and sprinkle it with some intuitive theory-crafting.

The relationship between micro and macro-economics, relative to human habits is quite interesting. Various factors such as perceived market conditions, supply and demand on a social level have strong effects on our reproductive existences.

For example, during the economic collapse, divorce rates decreased, to preserve a stable financial situation for many families.

The supply and demand factors for sex in college were interesting, when a male-to-female population difference occurs.

Then we have the statistics involved with online dating. By being provided a larger market for dating potential, relationships of higher quality have the potential to develop.

Varying data comes from marriage, which correlates heavily with education and income levels and longevity between partners. Low income individuals have a higher probability of divorcing (which correlates with lower levels of education), while vice versa for opposite side.

But then you have certain trade-off made by partners, including a wealthy male, who trades his assets, with a wealthy female whom trades her youth and beauty. This becomes more prominent in sex-tourism centric countries, or even the online marriage markets.

STD's have an interesting way of spreading, when you have 3 different types of receivers, coupled with someone who initiates sex. This includes a receiver who uses protection adamantly, a receiver who is neutral, and a receiver who prefers to avoid protection. Ultimately, 2/3 have a chance of propagating an STD if their partner is a carrier, and this will spread indefinitely.

Then we have happiness statistics, which states monogamous individuals have more sex, and are generally happier in life, than polygamous individuals. Not being on the dating market supports this statistics. Albeit, interestingly enough, women experience an orgasm 86% of the time with a new partner, compared to 50% of the time, with an existing partner.

Ultimately, an informative book on sociology, economic theory, and a bit of anthropology (history of societies). Good read for those interested in such topics.

I admit, I was keen on this book the moment I saw the title (and the brilliant cover of the Canadian edition). I was even more impressed when, what seemed like a light-hearted take on the intersection between sex and cash, turned into a serious examination of relationships and money. Marina Adshade is an economist by training and has produced convincing sketches of how the costs and benefits of modern dating, hookups, marriage, and even infidelity drive our actions. Adshade is clear that she doesn't think individuals calculate earnings lost or gained before jumping into bed with each other. She does argue, however, that the aggregate actions of people show, on average, why some decisions are more common than others. Among her topics are how an outnumbered male university population drives down the cost of sex; why widespread condom use produces an increased number of pregnancies; and why polygamy may, at times, help women. Adshade writes in clear and amusing prose (there are both double entendres and ribald speech), and she mixes vignettes from real people's sex and love lives into her hard-headed insights into data. This is a rare great book that is also fun. The only drawback is that it publishes after Valentine's Day.

The author kept inserting personal asides into my lovely math and stats book. I didn't think this one was as good as some of the other books I've read on this topic. But I am always a big fan of any book that looks at

A) what people actually do vs. what they say they do. And the author is right, online dating sites are a treasure trove of easy to access statistical information about that.

B) following the money. People don't do it consciously, but as groups we trend towards the best benefit with the least expenditure, and looking at those population trends is great fun, for us mathy marxist types.

Jared Diamond is probably the best writer on B, but I remember liking Marvin Harris, Cows, Pigs, Wars and Witches as well.

Iseng beli buku ini di Kindle Deals. Karena bukunya sudah 10 tahun lebih usianya, jadi saya langsung ulas dalam Bahasa Indonesia saja ya 😁

Buku ini ditulis oleh seorang doktor di bidang ekonomi yang mencoba untuk memahami perilaku manusia terkait dengan cinta dan seks melalui perspektif ekonomi. Misalnya, secara statistik, apa pengaruh tingkat pendidikan dan sosio ekonomi pada angka pernikahan dan perceraian. Menurut penulis, segala fenomena ini mestinya ada alasan ekonominya.

Buat saya, buku ini menarik sebagai latihan berpikir kritis saat berhadapan dengan statistik, misalnya ada studi yang menyebutkan bahwa laki-laki bertubuh relatif pendek, memiliki pasangan dengan rata-rata usia lebih muda daripada mereka yang bertubuh tinggi. Hal ini bisa dijelaskan dengan memahami bahwa laki-laki bertubuh lebih pendek biasanya menikah lebih lambat, setelah mereka lebih mapan secara kedewasaan dan situasi ekonomi sehingga fisik menjadi pertimbangan ke sekian untuk dipilih oleh calon pasangan mereka. Sementara itu, laki-laki bertubuh tinggi secara umum dianggap lebih menarik secara fisik sehingga menikah lebih cepat = angka rata-rata umurnya lebih kecil.

Buat saya pribadi bukunya Amerika Utara banget jadi banyak yang kurang relevan secara values dan kebiasaan, jadi sepertinya perlu studi lanjutan kalau mau dibawa ke konteks Indonesia 😂 Namun tetap ada beberapa insight yang berlaku universal kok.

I thought this book was excellent. It made the relationship between the supply and demand of the genders more understandable, all the while drawing links between biology, education, earnings and so on.

However, I read the edition called "The Love Market", under Harper Collins, and the book was riddled with typos and unedited errors. Not only was this incredibly distracting, but really disappointing as well. It's difficult reading something so socially relevant when words are misspelt, punctuation is missing, fractions of a sentence are repeated as though someone ctrl+c'ed it in... maybe I'm being nitpick-y, but that was really frustrating and does not reflect well on Adshade, either.

The author is someone I’m acquainted with, so I couldn't wait to read this book. I've previously read loads of popular economics books like Freakonomics, Naked Economics, Spousonomics and Dear Undercover Economist. Dr. Adshade is an economics professor who enticed undergraduate students with a course called The Economics of Sex and Love, and a resulting blog, Dollars and Sex. My summary is, if you think that dating, sex and marriage are no longer influenced by wealth, class and status, you are wrong!

I flew through this book in a few days because it was both fascinating and entertaining. It explores sexual behaviour through the eyes of economics and comes to some surprising (and amusing) conclusions.

I particularly liked the part where author Marina Adshade re-writes the traditional wedding vow with humour and brutal honesty.

Read it. You will never look at your relationship choices the same way again.

A book that could not hold my attention. The language was not clear and the writing was not focused. The author claimed that the use of the word Sex, helps her students to pay attention. True, that might be the reason many must have picked this book. But to keep the attention of your pupils and to satisfy their curiosity, it is important to deliver effectively all through the lecture or the book, in this case.

In the true tradition of popular economics, this book takes the analytical approach to human relationships. Some counterintuitive but evident insights are, send your daughters to schools with fewer women so that their value on the market is more, that women prefer same ethnicity except Asian women(just google this in Asia and you realize). Don't take it too seriously, but worth a read for laughs

Fascinating read. Economic perspective and insight on phenomenon in the sex and marriage market, topics ranging from teen promiscuity, single parent/mother, online dating, money/education/race in marriage, polygyny vs (serial in reality) monogamy, marriage quality, to STD and infidelity.

An interest look at how economics and sex blend together. I hope the female author has found that man she is looking for now! I skimmed much of the book but did like a number of the views presented as why we do things sexually as viewed thru an economic lens... it's a cute, quick read.

An economist perspective on sex and relationships. Adshade analyses the economic reasoning behind sexual behaviour. She applies concepts such as opportunity cost of capital to the choice of a husband/wife. Original and funny.

Enjoyable read on the connection between economics/commerce and our choices as cultures and individuals when it comes to relationships in general and sex in particular. It's funny in many places and extremely logical, but beware your sense of romance might be a bit battered afterward

Who knew that money and economy effects our sex lives. Makes sense when you think about it. But I didn’t find much useful stuff in the book, although I read only summaries and not the book itself.

The topics and anecdotes offered were interesting, and I appreciated the author's dedication to making them accessible. Unfortunately, its Cosmo-like tone (i.e. gimmicky and essentializing) meant that it was not nearly as informative, well-organized, or well-written as it had the potential to be.

Started out really interesting but then I slowly lost interest. The thoughts seemed to be all over the place. I think the concept of the book is something that should be considered when studying sexual behavior but I just couldn't finish it.

本来这个题材可以写的更有趣,结果发现这本书非常严肃像是个学术报告= =;不过内容还是相当好的相当好,要是跟Dr Tatiana's Sex Advice to All Creation一起看那真是相得益彰~(原来人和动物的行为根源差不多。。。)至于看完这本书对自己的生活有没有什么指导意义,只能说"然而并没有"。。。(人作为个体太渺小,很难避免行为被社会和基因所推动啊。。。)

This fun book applies basic economic analysis to explain, for example, why the increasing proportion of female students in colleges has led to more sexual promiscuity on campus and how the increasing importance of a college education leads to less teenage sex for all but the poor. Its basic idea that dating and marriage occur in a marketplace where everyone is both a buyer and a seller is a useful lens through which to view many aspects of the culture. The simple economic arguments have great power to explain; although, some aspects of sexuality remain irrational. The book might have been strengthened by a more systematic exploration of this irrationality through the lens of behavioral economics.

Loved this book. I read dateonimics in June and I was afraid this would be just like that book. This book actually discusses economic principles and isn’t afraid to touch on many different variables that affect the way people date and form relationships.
