Active and Cooperative Learning Using Web-Based Simulations

The author discusses the advantages of using computers and the World Wide Web in classroom simulation exercises. Using networked computers permits a richer simulation design, allows more complicated decisions by the students, and facilitates reporting results for later discussion. The Web is an ideal technology for such simulations because computers already have Web-capable browsers, with which students are familiar, and information on creating Web sites is readily available. The author discusses these points in the context of a sample simulation that teaches basic economic principles of trade, investment, and public goods in the context of American economic history.     

Wages and International Tax Competition

We introduce wage bargaining and private information into a model of profit shifting and tax competition between a large and a small country. Shifting profits to the small country not only reduces a firm's tax bill but also creates private information on profitability, altering the wage bargaining in favor of the firm. This additional shifting incentive makes the tax base of the large country more elastic and leads to higher outflows, lower wages, higher firm profits and lower equilibrium tax rates. Tax rates are no longer the only determinant of the direction and extent of profit shifting.     

Savings and investment in Australia

It has become popular to advocate tax reduction on the basis of promoting savings, investment and ultimately economic growth. The linkage between the variables is argued by various neoclassical growth models and is further suggested by recent studies which highlight the close association between domestic saving and investment rates. The close association may allow for polices which alter domestic saving levels in order to alter domestic investment levels. This interpretation, however, presumes an endogenous investment response. Equally likely, theoretically, is that the close association is maintained by movements in national savings. The present paper explicitly examines the endogeneity of the Australian saving and investment rates. The results highlight the exogeneity of investment. The results further suggest an endogenous response on the part of Australia's saving rate. The results may limit the potential benefits of these tax changes.     

Customer‐specific synergies and market convergence

We use an analytical model to study the effects of customer‐specific synergies, i.e., synergies that arise when firms sell multiple products to the same customers. At the firm level, we show that the profitability of a customer‐specific synergy depends upon cross‐market correlation of customer preferences, differs when the synergy is cost‐based versus differentiation‐based, and can even be negative when the synergy is kept proprietary to a single firm. We also show that returns to imitating such a synergy may decline as it strengthens. At the industry level, we find that exploiting customer‐specific synergies causes endogenous market convergence at a point that depends upon whether the synergy is cost‐based or differentiation‐based and whether it is imitated.

Assessing Tax Risk: Practitioner Perspectives

This study uses insights from tax practitioners and tax authorities to define and develop an estimate of ex ante tax risk that is independent of common tax outcomes studied in prior literature. Validation tests confirm that our tax risk measure (i) represents the predictable and unpredictable uncertainty inherent in the three sources of tax risk (i.e., economic risk, tax law uncertainty, and inaccurate information processing) and (ii) is a construct different from tax avoidance, tax uncertainty, and general business risk. Using our tax risk measure, we address two research questions of interest to academics and practitioners. First, we examine the association between tax risk and long-run tax avoidance and find a negative association between tax risk and future long-run cash effective tax rates (ETRs). Second, we consider the extent to which unrecognized tax benefits (UTBs) reflect tax risk, tax avoidance, or financial reporting incentives and demonstrate that our tax risk measure explains a substantial portion of UTBs, incremental and relative to measures of information risk, conditional conservatism, unconditional conservatism, and tax avoidance. Our study offers a measure of tax risk that, consistent with the Scholes-Wolfson paradigm, reflects the tax risk inherent in all business activities, not just tax avoidance activities; has unique industry effects; and contributes to our understanding of the factors that affect tax planning decisions and result in variation in firms' ETRs. Our findings will help managers and tax practitioners focus on industry-specific tax risk components, assess risk during tax planning initiatives, exercise caution when engaging in additional risk if ETRs are low, and adapt tax risk strategies to fit specific company needs. We enhance future tax research by improving the definition and measurement of tax risk.     

Sexual Orientation and Labor Force Participation: Findings from Chile and Uruguay

This is the first study that examines the association between sexual orientation and labor force participation in Chile and Uruguay. Using information on heads of households and their partners from recent census data, it applies a simple econometric methodology to measure the relationship of sexual orientation and labor participation, juxtaposing individuals who are part of straight and same-sex couples, while determining any difference in this association according to gender. The study finds that partnered gay men are up to 5.0 percentage points less likely to participate in the workforce compared to married straight men. In addition, lesbians are up to 32.7 percentage points more likely to participate in the labor force compared to married straight women. Trends between the two countries are similar, but the likelihood of participating in the labor force differs significantly. Conservatism in the cultural context and legal frameworks of each country arises as a possible explanation.     

Fully quantitative predictive maintenance/inspection planning optimization for chemical process plant components

Predictive maintenance/inspection planning and fitness-for-service analyses are being applied more frequently to address the effect of component aging affecting plant reliabibility. Component aging is one of the critical issues in an increasingly competitive environment, especially in plant components built and installed during the 50s and 60s. Maintenance optimization is also a critical issue for components, such as those that operate in the creep regime, and therefore age quickly. Maximizing the value received for each predictive maintenance/inspection dollar is the key. This article introduces the use of decision analysis to unite engineering analysis and economic evaluation for decision making. To illustrate this idea, examples of this approach applied to chemical facility components will be presented. In addition, the concept of priority-ranking multiple component maintenance/inspectio projects having maintenance budget and safety constraints in a way that maximizes Net Present Value, will be presented.     

More Than Rocket Science: A Case for Differentiated Leadership Development

Drawing on the research of Edwin Friedman (2007) in his book, A Failure of Nerve: Leadership in the Age of the Quick Fix, we explain the importance of developing differentiated leadership in groups and organizations of all sizes and types. According to Friedman, the leadership process is plagued by the fallacies of self, expertise, and empathy. These fallacies lead to an over reliance on data, low tolerance of ambiguity, anxiety, and a superficial comfort in togetherness, all of which upset the emotional balance in the leadership process. Using examples from rocket science, biology, and social psychology, we suggest that in order to combat these common dysfunctions, leadership development programs should be aimed at developing leaders who represent a nonanxious, self‐regulating presence. The goal of the current paper is to expand leadership development concepts and ideas to include practices that make groups and organizations more psychologically safe and enriching for all stakeholders.
