Effect of Limited Number of Interviews on Matching Markets
نویسنده
چکیده
We study outcome of two-sided matching between prospective medical residents who can only apply to a limited number of positions and hospitals who can interview only a limited number of applicants and show non-intuitive effects in the matching outcomes. We study matching size as our notion of efficiency, and show when the number of interviews is limited, a market with limited number of applications achieves a higher efficiency compared to a market with no limit. Also we find that a system of treating all applicants equally (setting the same limit for their number of applications), is more efficient rather than allowing a small set to apply to one more/less position. This comparison results in a scallop-shape figure 2 that shows expected size of matching with respect to expected number of applications. Finally we show that limiting number of interviews does not always hurt efficiency of matching markets and can improve social welfare in certain cases.

Natural Interviewing Equilibria for Stable Matching
Stable matching problems are ubiquitous, though much of the work on stable matching assumes that both sides of the market are able to fully specify their preference orderings. However, as the size of matching markets grow, this assumption becomes unrealistic, and so there has been interest in understanding how agents may use interviews to refine their preferences over subsets of alternatives. I...

Dividend policy has long been an issue of interest in the financial literature. To date, a number of studies published on agency costs and dividend policy but most of them are on developed markets, It is well known that the emerging markets are quite different from developed markets in all respects. So, the existing published evidence is of limited relevance in identifying the influence of agen...
متن کاملUsing Pseudo-Inverse to Eliminate the Limitation of the Number of Colors in Colorimetric Match
An algorithm is suggested for implementation of unlimited primaries in two-constants Kubelka-Munk color matching attempt. Allen's method for tristimulus color matching which was limited to four colorants in two constant theory, dealt with inversable matrices. By application of the pseudo-inverse, it is not necessary to limit the number of primary colors to four as Allen suggested. The suggested...

متن کاملON THE MATCHING NUMBER OF AN UNCERTAIN GRAPH
Uncertain graphs are employed to describe graph models with indeterministicinformation that produced by human beings. This paper aims to study themaximum matching problem in uncertain graphs.The number of edges of a maximum matching in a graph is called matching numberof the graph. Due to the existence of uncertain edges, the matching number of an uncertain graph is essentially an uncertain var...
