Are credit unions too small?
Since 1985, the share of U.S. depository institution assets held by credit unions has nearly doubled, and the average (inflation-adjusted) size of credit unions has increased over 600 percent. We use a non-parametric local-linear estimator to estimate a cost relationship for credit unions and derive estimates of ray-scale and expansion-path scale economies. We employ a dimension-reduction technique to reduce estimation error, and bootstrap methods for inference. We find substantial evidence of increasing returns to scale across the range of sizes observed among credit unions, suggesting that ...

Credit unions and the common bond
A distinguishing feature of credit unions is the legal requirement that members share a common bond. This organizing principle recently became the focus of national attention when the Supreme Court and the U.S. Congress took opposite sides in a controversy regarding the number of common bonds (fields of membership) that could coexist within a single credit union. In this article, Emmons and Schmid develop and simulate a model of credit-union formation and consolidation to examine the effects of common-bond restrictions on the performance of credit unions. The performance measures are ...

Conflict of interest between borrowers and lenders in credit co- operatives: the case of German co-operative banks
Over the last few decades, the co-operative banking sector in Germany has steadily increased its market share at the expense of other types of banks. This outcome is surprising from the standpoint of traditional economic thinking about co-operatives, which suggests that they are most appropriate for "backward" economies. We develop a model of co-operative banks that highlights the dual role ofmembers as borrowers and lenders. We show that a shift in the median (hence pivotal) member of the co-operative from predominantly a borrower orientation toward a lender orientation causes the ...

Membership structure, competition, and occupational credit union deposit rates
How do occupational credit unions set deposit rates? This article shows that the answer to this question will depend on (i) who actually makes business decisions in credit unions (who is in control), and (ii) whether local deposit market competition is important. It is not obvious who controls occupational credit unions. If the sponsor (the employer) is in control, then loans and deposits are priced to maximize the surplus received by all of the credit union?s current and potential members (those eligible to join). If members are in control, then a group of members with a majority can ...

Pricing and dividend policies in open credit cooperatives
This paper develops an integrated model of pricing and dividend policies in open credit cooperatives (those that do business with members and non-members on a non-discriminatory basis). We show that both the distribution of member preferences and the amount of non-member business the cooperative does influence its optimal pricing and dividend policies. For a fixed distribution of member preferences, the larger the fraction of business done by members, the smaller the optimal dividend and the larger the optimal pricing subsidy (hence, increasing demand). On the other hand, for a fixed fraction ...

Economies of scale and continuing consolidation of credit unions
This Economic Letter shows that, in contrast to banks, larger credit unions, on average, have decidedly lower average costs and higher net incomes, as we might expect in the presence of important economies of scale. It further notes that these economies of scale put pressure on the credit union industry to continue consolidating into fewer, larger credit unions. It also describes how some recent legislation may have further added to the pressures on both the banking and credit union industries to consolidate.

Banks vs. credit unions; dynamic competition in local markets
One interesting aspect of the financial services industry is that for-profit institutions such as commercial banks compete directly with not-for-profit financial intermediaries such as credit unions. In this article, we analyze competition among banks and between banks and credit unions using a dynamic model of spatial competition. The model allows for the co-existence of (for-profit) banks and (not-for-profit) credit unions. Using annual county-level data on banking market concentration and credit-union participation rates for the period 1989-96, we find empirical evidence of two-way ...

BANKING TRENDS: Credit Unions’ Expanding Footprint
Is there any evidence new rules could cause small banks to lose market share to credit unions? One of the main banking stories of the past 25 years has been the dramatic growth of large banks. Less well known is that credit unions have been expanding their market share during this time, too, especially after membership criteria were relaxed in 1998. While credit unions have been increasing their market share, small banks? market share has declined. And now, legal changes that took effect in January 2017 expanded credit unions? capacity to make loans to commercial customers, raising further ...
