Are There Increasing Returns to Scale in Marriage Markets?

The goal of an individual searching for a marriage partner is typically to form a long-term relationship. Marital search is a complicated and costly activity, where opportunities typically arrive over time at uncertain intervals, each party has to evaluate each other’s characteristics, and expectations play an important role. Given these features of marital search, a seminal paper by Mortensen ...

Characterization of efficient points of the production possibility set under variable returns to scale in DEA

  We suggest a method for finding the non-dominated points of the production possibility set (PPS) with variable returns to scale (VRS) technology in data envelopment analysis (DEA). We present a multiobjective linear programming (MOLP) problem whose feasible region is the same as the PPS under variable returns to scale for generating non-dominated points. We demonstrate that Pareto solutions o...

Implementation in production economies with increasing returns

In this paper we investigate incentive aspects of a general price-setting equilibrium principle in production economies with increasing returns or more general types of non-convexities. We do so by introducing the notion of generalized mechanism. We allow preferences and individual endowments to be unknown to the planner. We present a simple generalized mechanism whose social equilibrium alloca...

Are there Economies of Scale in Stock Exchange Activities?

This is the first paper that examines economies of scale in stock exchanges. The data employed in the study include cost and output statistics for 37 stock exchanges in four continents around the world for the year 1997. I estimate two traditional cost functions and find that ray (overall) scale economies exist only in the very large stock exchanges but that there are significant scale economie...
