The Theory of the Business

The term “platform” is on everyone’s lips. Startups that hope for high financing rates are using it to promote their business idea – a successful platform promises power, influence and high profits. But what characterizes platforms and their business model?

What do economic theories such as the Nash equilibrium and the on internet matchmaking services in favour of face-to-face dating events.

What do speed dating, applying to a state secondary school and undergoing a potentially life saving transplant from an organ donor have in common? It might take an economist to notice that all three can be seen as markets — but ones where no money changes hands. Alvin Roth and Lloyd Shapley have won the Nobel prize for their work on how these difficult choices can be made without using prices as a mechanism.

Shapley first dared in to tackle the question asked by women’s magazines through the years — how to find a suitable match. The specific question he sought to answer was: how could individuals in a group be paired up when they all had different views on who would be their best match? Along with economist David Gale, Shapley developed a method to match 10 women and 10 men, so that no two people would prefer each other over their current partners.

Traditional heterosexual dating apps have a fatal flaw: women get flooded with low-quality messages — at best vapid, at worst boorish — to the point where checking the inbox becomes an unappealing chore. Partly as a result, men see most of their messages ignored. Nobody is happy, but nobody can do anything about it. Well, none of the users, individually, can. But a new generation of dating apps impose limitations on daters that might liberate them.

Downloadable! Parental involvement in matchmaking may distort the choice of spouse because parents are willing to substitute love for market and household.

Allocation procedures have recently become a new and exciting field of economic research, with a wide range of applications. Since the seminal work by Gale and Shapley and Shapley and Shubik , matching theory has developed and matured to a point where matching theorists could guide designs of medical match and other entry-level labor markets, school choice, course allocation and organ donation, among others.

This course will introduce you to the frontier of research, including theoretical developments, applications, and empirical analysis. Important: within the context of the covid international health crisis, the PSE Summer School has been cancelled. The course will provide a thorough presentation of the basics of the economics of matching both on theory and empirical grounds. The course will also present the frontier of knowledge in the field as well as the questions to be explored and will certainly be an important stepping stone for students who are planning to work on related topics.

The prior knowledge of matching theory is definitely useful when it turns to appropriately designing these algorithms. Further, administrations involved in policy evaluations may benefit from learning the most recent tools to assess the performance of assignment schemes.

Zero-Sum Game

We consider a matching market, in which the aim is to maintain a popular matching between a set of applicants and a set of posts, where each applicant has a preference list that ranks some subset of acceptable posts. The setting is dynamic: applicants and posts can enter and leave the market, and applicants can also change their preferences arbitrarily. After any change, the current matching may no longer be popular, in which case, we are required to update it.

Life-saving kidney exchange programmes are just one of the practical applications of the market-matching theories for which American.

This simple premise is at the core of economic thought. But with surprising frequency, prices are not enough and can even be irrelevant. Decades later, in , this body of work was recognized with the Nobel prize. Economics is often deemed impractical—too abstract from the real world to have pragmatic importance. This careful analysis led to a invitation from doctors who had found that the growing number of married couples seeking hospital posts undermined the existing algorithm.

No longer were matches stable. Roth helped redesign the algorithm, used with success ever since. Others have extended it into financial intermediation, Internet advertising auctions and even dating services. Region: Perhaps we could begin with some general background on matching markets. They have to hire you. You also have to be chosen. Roth: Well, it might be easiest to first talk about commodity markets because they are markets where we think price does do all the work. It takes a lot of design to make something into a commodity market.

Take wheat, for example.

Out of all the areas of public life that can benefit from the applications of behavioural economics BE principles, healthcare is probably the one where it can make the biggest societal contribution. There are two main reasons why the healthcare industry should welcome more! The first reason is that many of the traditional ways in which marketing and economics principles have been applied to health are starting to show their limits e.

In this post, I highlight ways in which some of the key principles of BE have been — or could be — applied in a healthcare context. They showed how simple interventions, such as registering individuals by default on the organ donation register people have to opt out if they do not wish to be a donor , could significantly increase organ donations. Focusing on smaller, short-term goals — e.

When Coffee Meets Bagel launched, one selling point was its enforcement of such a policy: users received just one match per day. (Coffee Meets.

These fights are looking more and more like political campaigns. The Economics and Statistics Administration of the U. One central area of argument relates to whether the sharing economy is simply bringing more wage-earning opportunities to more people, or whether its net effect is the displacement of traditionally secure jobs and the creation of a land of part-time, low-paid work. While the conclusions about the overall effects of this sector are anything but clear, even as more data pour in, it is worth digging into the available literature and knowing the centers of research debate and lines of argument.

Those conclusions have been critiqued by, for example, the liberal-leaning Center for Economic and Policy Research. There is the distinct danger, on both sides, of overstating the case and the size of effects. A paper by Annette Bernhardt of University of California, Berkeley, signals a cautionary note about any claims of radical recent change being wrought across the U. Yet at least with aggregate national data, it has been hard to find evidence of a strong, unambiguous shift toward nonstandard or contingent forms of work — especially in contrast to the dramatic increase in wage inequality.

This is not to say that there have been no changes in the workplace.

Love, money, and old age support : does parental matchmaking matter ?

Not in a very long time—not, perhaps, since the late s or early s—have there been as many new major management techniques as there are today: downsizing, out-sourcing, total quality management, economic value analysis, benchmarking, reengineering. Each is a powerful tool. But, with the exceptions of outsourcing and reengineering, these tools are designed primarily to […].

But, with the exceptions of outsourcing and reengineering, these tools are designed primarily to do differently what is already being done. The story is a familiar one: a company that was a superstar only yesterday finds itself stagnating and frustrated, in trouble and, often, in a seemingly unmanageable crisis.

There has been a large number of theoretical analyses and the theory matured to a point where matching theorists could make policy suggestions in key areas.

Scholars in economics have long attempted to quantify the most philosophically intangible concepts such as fairness and equity. In the United States, fairness of affirmative action in higher education has become one of the most controversial social issues. Using mathematical theories, economists have already worked on assessing fairness in affirmative action policies for more than a decade.

The goal of this academic inquiry is to study mechanisms related to matching students to schools while maintaining a balance of diversity. But in this field of inquiry, how is fairness measured? Is the current system fair? If so, why are there so many social concerns arising from the existing system? Will stating their true preference ensure a better outcome? With these two concepts in mind—fairness and strategy-proofness—what are the current systems used?

Are they fair? Are they strategy-proof? Currently, the most prevalent mechanisms used are the quota and reserve system. Quota puts an upper numerical bound on the number of students admitted.
