Do bank mergers have hidden or foregone value? Realized and unrealized operating synergies in one bank merger

Abstract Recent mergers in the banking industry have often generated disappointing shareholder returns. Delays in implementing potential operating savings and realizing benefits of scale economies may be one reason these mergers have disappointing returns. Using data envelopment analysis (DEA), we analyze a 200-branch network formed in a merger of four banks. The operating efficiency of each branch is benchmarked against “best-practice” branches in the combined merged bank as well as “best practice” branches within each pre-merger bank. This analysis identified opportunities to reduce branch operating costs by 22 percent for the entire merged bank. In contrast, the cost savings opportunity is under seven percent when analyzed within each pre-merger bank. These findings suggest benchmarking across the entire merged bank to identify the best practices bank-wide can generate added savings. However, in this bank merger, these merger benefits were not realized until four years after the merger. Interviews with key players in the merged bank indicate that the bank deferred realizing these benefits because of political pressures, personnel integration issues, system integration issues, and financial components of the merger such as restructuring reserves and the purchase price. These causes suggest areas where shareholders can and should demand more rapid improvement in performance of bank mergers and areas for future corporate merger research.

The effects of observing a peer's likelihood of reporting income on tax reporting decisions

This study examines the influence of peers in the tax compliance setting using a social learning theory approach to investigate the effect of observing a peers likelihood of reporting income. We also examine the role that gender plays in these decisions. We ask participants to estimate the likelihood of reporting income and to make a binary compliance decision in a setting where they are able to observe what they believe is anothers response to a hypothetical tax reporting scenario. Participants who viewed the decision of a noncompliant peer were less likely to report honestly than those who viewed the decision of a compliant peer. This finding provides further evidence of a potential effect for peer influence. Consistent with prior literature, we find that women are more likely to comply than men, but do not find an interactive effect with peer observation. A supplemental experiment indicated that participants who believed their responses would be seen by a peer were less likely to report honestly than participants who believed their responses would remain private. This result, although counter-intuitive, is consistent with Wenzels (2005a) description of a self–other discrepancy and conformance to a misperceived social norm.

Tax policy and planning implications of hidden taxes: effective marginal tax rate exercises

Abstract Hidden taxes in the form of floors and phaseouts are prevalent in the current US tax system and can have a considerable impact on the marginal tax rate faced by the taxpayer. It is important that future tax professionals be familiar with the theoretical and practical implications of hidden taxes. This paper provides a series of classroom exercises to illustrate the impact that hidden taxes can have on marginal tax rates. Information for incorporating this material into an introductory tax course is also provided. The exercises help inform students about the impact of specific tax provisions on marginal tax rates and business and investment decisions, while also giving instructors an opportunity to discuss the tax policy considerations that lead to implementation of these provisions.

The Effect of Federal-State Conformity on Taxpayer Decisions

Abstract We conduct an experiment asking participants to choose to purchase either a traditional or hybrid car to examine how federal-state conformity of tax incentives impacts the decisions of taxpayers. We also examine perceptions of taxpayers surrounding federal-state conformity. Consistent with theory related to the effects of information environment and using an experiment in which taxpayers are asked to evaluate tax incentives related to a purchase decision between a traditional and hybrid car, we find that conformity is a significant factor in increasing the propensity to take advantage of the tax incentive. Specifically, we find that participants with simple and conforming federal-state incentives are more likely to take advantage of the tax incentive than with complex and conforming federal-state incentives. In addition, the effects of conformity between federal and state incentives suggest that participant perceptions of the federal system were heavily influenced by the actions of the state.

Social Security Reform: Exploring the Generational and Racial Divide

Increased life expectancies and decreased birthrates have placed enormous financial pressure on the Social Security system. Because significant reforms are needed to ensure its financial solvency, our study examines the acceptability of proposals to reform the system. Given the potentially divergent views suggested by prior research, we selected participants from the following four groups (1) younger black taxpayers, (2) younger white taxpayers, (3) older black taxpayers, and (4) older white taxpayers. While there was agreement among the groups on several of the proposals, in general, the differences between the generations were more pronounced than the differences between the racial groups.

Yours, Mine, or Ours: Tax-Related Decision Responsibility of Married Couples

Abstract Purpose Examine tax-related decisions of married couples to determine whether decisions are made jointly or if one spouse dominates the decision. We also examine characteristics related to decision styles. Methodology/approach Questionnaires completed independently by both the husband and wife. Findings Nearly 40 percent of the couples make tax decisions jointly, while the remaining couples allow one spouse to dominate tax-related decisions. The results indicate that when one spouse dominates the decisions, it is most often the wife. We also find that couples are more likely to share tax-related decision responsibility jointly when the husband earns significantly more than the wife, when the couple has greater income as a family, and when they are a new couple. Research limitations/implications Prior research has generally not recognized tax decisions by married couples as a joint decision or attempted to determine whether tax decisions are dominated by the husband or wife. This issue has implications for interpreting research results in light of prior research that has found that tax-related decisions vary significantly by gender. The finding that many couples make joint decisions suggests that an interesting avenue for future research would be to determine the nature of that joint decision making and whether it is collaborative, bargaining, or something else. Originality/value Prior research on tax-related decisions has not recognized that for approximately 40 percent of tax returns filed, the unit of study is not a single individual but a married couple.
