Assortative Matching and Search
- ECONOMETRICA
, 2000
"... In Becker's (1973) neoclassical marriage market model, matching is positively assortative if types are complements: i.e. match output f(x, y) is supermodular in x and y. We reprise this famous result assuming time-intensive partner search and transferable output. We prove existence of a sea ..."

f , but also of log f x and log f xy . Symmetric submodularity conditions imply negatively assortative matching. Examples show these conditions are necessary.
Cross-Subsidization and Matching Design
, 2013
"... We develop a theory of price discrimination in many-to-many matching markets in which agents’ preferences are vertically and horizontally differentiated. The optimal plans induce negative assortative matching at the margin: agents with a low value for interacting with other agents are included in th ..."

Matching Information ∗
, 2012
"... We analyze the allocation of heterogeneous experts to teams of fixed size. Experts differ in the precision of their information about an unknown state and make a joint decision, aggregating their potentially correlated information. In this setting, we study the assortative matching properties (Becke ..."

(Becker (1973)) of teams. The main insight is that it is optimal to diversify the composition of each team. This diversification is a generalization of negative assortative matching (NAM) to large teams, as it arises when the team payoff is submodular in their members’s characteristics. When experts
Self Help Group Linkage Programme: A case-study
, 2006
"... The case-study examines the group lending mechanism of a particular Microfinance Institution working in Haryana, India. The Microfinance Institution restricted the number of group members that could borrow simultaneously from it and allowed the internal lending amongst the group members. We found ev ..."

evidence of negative assortative matching in groups i. e. relatively wealthy individuals grouping with poorer individuals, with the wealthier members obtaining a higher proportion of the loans in the group.
Preference-based matching in marriage markets
, 2003
"... This paper studies a marriage market with heterogeneous preferences. Individuals have incentive to assort based on utility function properties. I derive a measure of how individuals value prospective partners ’ preferences; the quality-of-match between two individuals depends on a weighted average o ..."

of their evaluations of each other. Two types of preference-based assortative matching unambiguously shift the household Pareto frontier outward: positive assortative matching based on first-order characteristics of utility functions (individual optima) and negative assortative matching based on second
A Two-Sided Matching Model of Monitored Finance. Kaniska DAM CORE DISCUSSION PAPER 2007/05 A Two-Sided Matching Model of Monitored Finance∗ Kanis.ka Dam
"... We analyse a model of two-sided matching and incentive contracts where expert investors (venture capitalists) with different monitoring capacities are matched with firms with different levels of initial wealth. Firms do not have sufficient start-up cap-ital to cover their project costs and hence, se ..."

The Sorting Effect of Price Competition
, 2007
"... –Preliminary draft – We investigate under which conditions price competition leads to sorting of buyers and sellers. In a decentralized Walrasian market where sellers post prices and buyers choose whom to buy from positive assortative matching obtains only if there is a high enough degree of complem ..."

of complementarity between buyer and seller types. The relevant condition is root-supermodularity; i.e., the square root of the match value function is supermodular. This condition is weaker than log-supermodularity, a condition required for positive assortative matching in markets with random search. Negative
An Empirical Examination of Matching Theories: The One Child Policy, Partner Choice and Matching Intensity in Urban China
"... This paper introduces an index that facilitates the testing of differing matching theories based on the degree of overlap between a theoretically generated matching joint density and its empirical counterpart. The index is asymptotically Normal, consequently permitting inference. To demonstrate its ..."

Group-lending with sequential financing, contingent renewal and social capital
- Journal of Development Economics
"... This paper focuses on the dynamic aspects of group-lending, in particular sequential financing and contingent renewal. We examine the efficacy of these two schemes in harnessing social capital. We find that, for the appropriate parameter configurations, there is homoge-nous group-formation so that t ..."

that the lender can ascertain the identity of a group without lending to all its members, thus screening out bad bor-rowers partially. Moreover, under certain parameter configurations, negative assortative matching occurs as a robust phenomenon. Key words: Group-lending; sequential financing; contingent renewal
Beyond Microcredit: Giving the Poor a Way to Save Their Way out of Poverty
, 2011
"... The implicit assumption in microfinance literature has been that offering the poor credit is the most efficient way to alleviate poverty. This paper examines the optimal design of group-lending microfinance institutions that offer both saving and borrowing opportunities. Offering saving opportunitie ..."

opportunities requires restricting credit within the group that leads to negative assortative matching within the group along wealth lines, i.e., there is significant wealth heterogeneity within the endogenously formed groups. Further, the paper shows that under some reasonable assumptions, the microfinance
