Both rematching proof and strong equilibrium outcomes are stable with respect to the true preferences in the marriage problem. We show that not all rematching proof or strong equilibrium outcomes are stable in the college admissions problem. But we show that both rematching proof and strong...

Consider a society with a finite number of players. Each player has personal preferences over coalitions in which he joints. A social outcome is a coalition structure that is defined by a partition of the set of players. We study the strategy proof core and von Neumann and Morgenstern (vN&M)...

Consider a society with a finite number of individuals. A coalition structure is a partition of the set of individuals. Each individual has personal preferences over the set of all coalition structures. We study the strategy proof core and von Neumann and Morgenstern (vN&M) solutions. A roommate...

Robert Barsky and Jeffrey Miron (1989) revealed the seasonal cycle of the U.S. economy from 1948 to 1985 was characterized by a "bubble-like" expansion in the second and fourth quarters, a "crash-like" contraction in the first quarter, and a mild contraction in the third quarter. We replicate,...

This paper studies the $\alpha-$double auction in Xu et al. (2014) and extends their results to the case where $\alpha$ is time-varying in a manner governed by a time non-homogeneous Markov chain specified in Ram et al. (2009) over a set of states defined by $R\equiv\{\alpha_1, \alpha_2, \cdots,...

A new FIR filter is designed to date U.S. recessions with the unemployment rate and the Conference Board employment trend index. Our approach is simple but one can see from the curve the dynamic process how the economy moves from one business cycle to the next. We also present a new use of the...

How is it possible to successfully time the stock market using publicly available information if the market prices evolve according to a random walk in a rational market? Our paper answers this question by providing nine strategies to time the S&P500 index, using two specific real variables as...
