The Walras-Bowley Lecture: Fragmentation of Matching Markets and How Economics Can Help Integrate Them
Yuichiro Kamada, Fuhito Kojima, Akira Matsushita
Fragmentation of matching markets is a ubiquitous problem across countries and across applications. In order to study the implications of fragmentation and possibilities for integr…
Bertrand Menu Competition
Fuhito Kojima, Bobak Pakzad-Hurson
We study a variation of the price competition model a la Bertrand, in which firms must offer menus of contracts that obey monotonicity constraints, e.g., wages that rise with worke…
Equal Pay for Similar Work
Diego GentilePassaro, Fuhito Kojima, Bobak Pakzad-Hurson
Equal pay laws increasingly require that workers doing "similar" work are paid equal wages within firm. We study such "equal pay for similar work" (EPSW) policies theoretically and…
Market Design with Distributional Objectives
Isa E. Hafalir, Fuhito Kojima, M. Bumin Yenmez +1
We provide optimal solutions to an institution that has distributional objectives when choosing from a set of applications based on merit (or priority). For example, in college adm…
Efficient Market Design with Distributional Objectives
Isa E. Hafalir, Fuhito Kojima, M. Bumin Yenmez
Given an initial matching and a policy objective on the distribution of agent types to institutions, we study the existence of a mechanism that weakly improves the distributional o…
Selfish Mining Attacks Exacerbated by Elastic Hash Supply
Yoko Shibuya, Go Yamamoto, Fuhito Kojima +3
Several attacks have been proposed against Proof-of-Work blockchains, which may increase the attacker's share of mining rewards (e.g., selfish mining, block withholding). A further…
"Near" Weighted Utilitarian Characterizations of Pareto Optima
Yeon-Koo Che, Jinwoo Kim, Fuhito Kojima +1
We characterize Pareto optimality via "near" weighted utilitarian welfare maximization. One characterization sequentially maximizes utilitarian welfare functions using a finite seq…
Equilibrium of Blockchain Miners with Dynamic Asset Allocation
Go Yamamoto, Aron Laszka, Fuhito Kojima
We model and analyze blockchain miners who seek to maximize the compound return of their mining businesses. The analysis of the optimal strategies finds a new equilibrium point amo…
Monotone Comparative Statics without Lattices
Yeon-Koo Che, Jinwoo Kim, Fuhito Kojima
The theory of Monotone Comparative Statics (MCS) has traditionally required a lattice structure, excluding certain multidimensional environments such as mixed-strategy games where…
Interdistrict School Choice: A Theory of Student Assignment
Isa E. Hafalir, Fuhito Kojima, M. Bumin Yenmez
Interdistrict school choice programs-where a student can be assigned to a school outside of her district-are widespread in the US, yet the market-design literature has not consider…
