The Band Pass Filter*

We develop optimal finite‐sample approximations for the band pass filter. These approximations include one‐sided filters that can be used in real time. Optimal approximations depend upon the details of the time series representation that generates the data. Fortunately, for U.S. macroeconomic data, getting the details exactly right is not crucial. A simple approach, based on the generally false assumption that the data are generated by a random walk, is nearly optimal. We use the tools discussed here to document a new fact: There has been a significant shift in the money–inflation relationship before and after 1960.

Ranking Journals Using Social Science Research Network Downloads

I use a new approach to rank journals, namely the number and percent frequency of articles a journal publishes that are heavily downloaded from the Social Science Research Network (SSRN). I rank 18 accounting and finance journals, and I identify five journals not considered by the two most recent major published ranking studies of publications by accounting faculty, namely (in rank order): Journal of Financial Economics, Review of Accounting Studies, Review of Quantitative Finance and Accounting, Journal of Corporate Finance, and Journal of International Financial Management and Accounting. I show that financial accounting faculties are more likely to post their working papers to SSRN, and papers posted by financial faculties generate more downloads. I mitigate this bias in favor of the financial area by providing separate rankings based on authors in the financial versus non-financial areas.     

Assessing the international spillover effects of capital income taxation

Changes in capital taxes by one economy spill onto other economies with internationally mobile capital. We evaluate these impacts using a two-region, intertemporal general equilibrium model. The foreign economy's unilateral reduction in corporate income taxation has positive but small effects on U.S. welfare. In contrast, unilateral reductions in personal income taxation impose large negative spillovers. The differences result from CIT being source-based and PIT residence-based. The CIT cut reduces tax burdens to U.S. residents who invest abroad, while the PIT cut reduces foreigners' tax burdens only. Through general equilibrium adjustments neglected in simpler models, the PIT cut lowers U.S. residents' welfare.     

Econometrics and equilibrium models

In Rational Econometric Man, Edward Nell and Karim Errouaki present a welcome and timely case for the view that econometrics and econometric model-building may not be the magic tools to solve all empirical questions despite what many seem to have thought they were in the 1960s. Here I examine some possible problems with econometric models that have to do with their usually taking the form of equilibrium models. Some of these problems were recognized by Trygve Haavelmo decades ago. And as Aris Spanos has recently discussed, the problems are often the result of what we say in our textbooks. Some problems have to do with what we mean by econometric parameters and others with how we use probabilities.     

When it pays to have a friend on the inside: contingent effects of buyer advocacy on B2B suppliers

As organizational buying systems grow more complex and sophisticated, suppliers increasingly rely on buyer advocacy: an individual buyer’s efforts to influence his/her colleagues such that the supplier’s standing is improved. Drawing from cognitive response theory, the authors hypothesize an inverted U-shaped relationship between a buyer’s advocacy for a supplier and the customer’s purchases from that supplier. They theorize that this effect is moderated by the advocate’s industry experience and customer–supplier relationship characteristics. An analysis of multisource data from a B2B service provider (Study 1) supports the predicted inverted U-shaped relationship, while a unique dataset from a large industrial supplier (Study 2) provides broad support for the hypothesized moderators. Finally, a randomized experiment (Study 3) replicates key findings and corroborates the theorized cognitive response mechanisms. Findings contribute to the limited literature on buyer advocacy within the organizational buying domain and offer practical implications for suppliers and buyers.

     

To push performance,check the leader’s power motive

The power motive, defined as the desire to impact the behavior and emotions of another person, has long been controversial. On one side, the exercise of power has been put forth as a fundamental human need greater in strength than the need to survive. On the other, it has been vilified for its potentially devastating consequences. We argue the latter view is distorted, and, by relying too heavily on it, we have come to misunderstand the essential nature of power and its use by leaders charged with driving performance. It is not the power motive that leads to corruption and tyranny, but rather how the power motive is channeled into behavior by other personality factors. Consequently, those charged with leader selection should place greater emphasis on how individuals with strong power motives differ in how they channel power. Doing so will support the selection of executives best equipped to deliver organizational performance.
