This book is the third in the Harvard Economist Reasoning Series. Spearman accepted the commission from a foundation established by an American entrepreneur and came to the University of Cambridge in England to help negotiate the purchase of the former residence of economist Marshall. Marshall was Keynes's teacher and the father of modern economic theory. His former residence, Berry Riot, is well-known in the economic circle. His masterpiece "Principles of Economics" was written here. Unexpectedly, before the house purchase plan was settled, the American entrepreneur who was traveling with him was attacked mysteriously and almost died. Later, the dean of the Bishop's College was murdered in a horrifying way, making the house purchase trip even more dangerous. The enlightened Spearman risked his life and fought face to face with the cruel and cold-blooded killer! In the book, the concepts of the great economists Marshall, Bentham, Adam Smith, and Keynes will appear... Let's see how Spearman uses "information asymmetry" to solve murder cases.

This book is the fourth in the Harvard Economist Reasoning Series. Henry Spearman, who had just become a new Nobel Prize winner in economics, was invited to serve as a visiting professor at the University of Monte Vista. At the beginning, a bizarre art theft occurred on campus. Later, he originally planned to teach the "Art and Economics" course, but was forced to face the case of Tristan Wheeler, the resident artist who was rumored to have committed suicide. In Spearman's guest lecture class, students and Spearman excitedly thought about Adam Smith's metaphor, how the supply, demand and pricing of art are different from those of general commodities, and what factors affect supply, demand and price. While Spearman was pleased that the students were continuing to think about the fascinating field of economics in an economic way of thinking, he did not expect that this class would also gradually make the situation of the campus murder gradually clear, and the powerful enemy and murderer lurking behind it would emerge. Once again, Spearman sets out to find the truth.

Extracurricular readings designated by the economics departments of hundreds of universities in the United States, highly recommended by three Nobel Prize winners in economics; the Harvard Economist Reasoning Series consists of four volumes. Spearman uses economic tools to develop four stories: find out the secrets behind "irrational behavior"; find hidden secrets according to the logic of "maximizing consumer utility" The truth about art; a wonderful debate at the University of Cambridge, Chicago School VS Keynesian School; another attack in the field of "art and economics", identifying the real culprit based on the supply and demand relationship and price trends of art works; a seamless combination of reasoning and economics, learning economics knowledge while reading interesting mystery novels...

This book is the second in the Harvard Economist Reasoning Series. Dennis Gossen - a promising young academic - is suspected of committing suicide. From the perspective of rational economic analysis, whether he can stay at Harvard or not, there are great prospects waiting for him. But he actually believed that the opportunity cost of suicide was much lower than the emotional cost of not getting tenure. The cost-benefit calculation of suicide is really unbelievable to Dennis Gossen, who studied economics. However, it's not over yet. Two members of the tenure review committee were murdered one after another. Who was behind the three deaths? Henry Spearman used his consistent economic thinking to find doubts. Henry Spearman knew very well that the murderer was among the committee members, but what distinguished professor would be greatly increased in effectiveness by murdering other colleagues?

This book is the first in the Harvard Economist Reasoning Series. On the wooded island of St. John in the Caribbean, the Laurel Bay Cane Garden Hotel is an ideal holiday destination. But for Henry Spearman, a Harvard economics professor who came for vacation, the place also gave him an unexpected proposition: murder. The police investigation on the island was almost completely on the rocks, and Spearman, a short, bald man who liked to use human behavior to train his curiosity, conducted his own investigation, but he used completely different laws-the principles of economics. At the heart of this story is a mystery: someone's behavior is invisible to everyone, but people don't know what is being hidden. When Spearman sees someone behaving irrationally and not achieving their goals at the lowest cost on the surface, he knows there must be something fishy. As long as he fully observes these "irrational" behaviors, he can deduce the problem of the other party.
