Exploiting old customers and attracting new ones: The case of bank deposit pricing

Recent theoretical contributions suggest that deposit interest rates should be higher in geographic areas characterized by greater in-migration and lower for depositors at banks with greater shares of existing (or so-called “locked-in”) depositors. These hypotheses are tested using a rich data set obtained for the Spanish banking industry. Results confirm that, all else equal, banks offer higher deposit rates in territories characterized by greater in-migration, and also that they tend to offer lower rates, the larger the number of their locked-in depositors. These findings confirm the existence of the trade-off between exploiting old customers and attracting new ones.

The Relaxation of Entry Barriers in the Banking Industry: An Empirical Investigation

Until recently, state laws restricted entry into local banking markets in many states by limiting both branching and multibank holding company (MBHC) operations. To the extent that these laws impeded entry into local banking markets, the removal or relaxation of the restrictions should have reduced barriers to entry, leading to more competitive price levels in the affected markets. This paper tests for such effects by examining the changes in deposit interest rates offered by banks operating in markets affected by liberalization of state banking law relative to the changes in deposit interest rates offered during the same time period by banks operating in markets not affected by such liberalization. We find evidence that liberalization of state laws restricting intrastate MBHC operations, interstate branches, and interstate MBHC operations caused deposit interest rates to become more competitive. We, however, find no evidence of such effects associated with the removal of restrictions on intrastate branching.     

An analysis of the cost of providing ancillary services to skilled nursing facility patients in New York State

Currently, nursing homes can arrange for the provision of ancillary services either by providing the services directly, purchasing the services through contracts and fees, or by outside billings, in which the services are supplied by other providers who then bill Medicaid directly. Frequently, some combination of these three modes of provision is used for each ancillary service. The purpose of this study is to explore ancillary costs in a sample of nursing homes and to determine, to the extent possible, the most cost-efficient means of providing selected ancillary services (physical therapy, radiology and medical staff services). Prior to examining the impact of the mode of provision on cost levels, other facility and patient characteristics that might justifiably affect costs are identified and adjusted for. The results demonstrate that outside billing or purchasing services can be much less expensive than providing the services directly. It is suggested that all ancillary services (outside billings as well as services provided directly through contracts and fees) be included when facility-to-facility cost comparisons are made. This approach should serve as an incentive for nursing homes to seek the most cost-efficient means of providing ancillary services.     

The Effect of Information Systems on Honesty in Managerial Reporting: A Behavioral Perspective*

This study examines the behavioral impact of an information system, and how that impact varies with the information system's precision, in an internal reporting environment. We propose that a manager's reporting decisions are affected by his or her trade‐off of the benefits of appearing honest against the benefits of misrepresentation. The information system affects the manager's trade‐off by improving the owner's ability to make an inference regarding the manager's level of honesty. Thus, to the extent that the manager perceives benefits to appearing honest, the presence of an information system can increase managerial honesty. As the information system becomes more precise, however, the manager must forgo greater benefits of misrepresentation in order to achieve the same appearance of honesty. For managers under a precise system, this will shift the trade‐off decision toward the benefits of misrepresentation and away from the benefits of appearing honest. Notably, in our experiment, the only benefit of appearing honest is an intrinsically motivated desire for social approval. We find that, although the existence of an information system increases managerial honesty, honesty is lower under a precise than under a coarse information system. We also compare profit earned by the owners in our experiment, which relies on a behavioral role of an information system, with the maximum profit theoretically possible given a contractual use of the information system. This comparison suggests that, unless the available information system is sufficiently precise, the owner will obtain greater profits by not contracting on its output, even if that output is fully contractible.     

Discussion of “Communicated Values as Informal Controls: Promoting Quality While Undermining Productivity?”

Kachelmeier, Thornock, and Williamson ( 2016 ) investigate experimentally whether an employer's value statement can affect the way employees cognitively represent how they should approach a multi‐attribute task, and therefore performance. Counter‐intuitively, but consistent with their theory, they find that the value statement negatively affects performance for piece‐rate incentivized participants. In my discussion, I elaborate on my comments from the 2013 CAR Conference. Specifically, I discuss contexts where a firm's value statement may have positive effects on performance, and the importance of conducting research investigating how the decisions made by management accountants affect learning.     

Do Substantial Horizontal Mergers Generate Significant Price Effects? Evidence From The Banking Industry

This study examines the price effects of recent US bank mergers that substantially increased local market concentration. Using the deposit interest rates that banks offer their customers as our price measure, we find that, over the 1991–94 time period, deposit rates offered by participants in substantial horizontal mergers and their local market rivals declined by a greater percentage than did deposit rates offered by banks not operating in markets in which such mergers took place. We interpret our results as evidence that these mergers led to increased market power.     

ATM surcharge bans and bank market structure: The case of Iowa and its neighbors

It is frequently claimed that high ATM surcharges actually attract customers to the banks that impose them, particularly if they operate large ATM networks. By exploiting as “natural experiments” two events associated with the lifting of surcharge bans in Iowa and in the states that neighbor Iowa, this paper seeks to test for the implications of this phenomenon as it applies to the market shares of banking institutions and to several aspects of market structure. Consistent with predictions, results of “difference-in-difference” analyses suggest that the retail account shares of larger market participants increased relative to those of smaller competitors, market concentration increased, and the number of market competitors decreased after the lifting of surcharge bans – all relative to what would have occurred had there been no change in authority to surcharge.
