An engineering economy concept inventory

Abstract

There has been considerable recent emphasis on valid assessment of learning in engineering education. When new teaching pedagogies are introduced, it can be very challenging to demonstrate increases in learning of course concepts. While there are a number of accepted concept inventories available for some engineering topics (statics and dynamics, heat and energy, signals and systems, and statistics), reliable and valid tools for assessing learning are not readily available for many curriculum areas, including engineering economy. This paper discusses the reliability and validity of the Engineering Economy Concept Inventory (EECI) that can be used to assess learning in any introductory engineering economy course. Development of the EECI began in 2009 for use in assessing the effectiveness of model-eliciting activities in the classroom and has since been revised and reformulated a number of times. In the fall of 2018, the EECI was administered at multiple institutions for further evaluation of its validity and results from these groups of students are presented. The paper concludes with remarks regarding the reliability and validity of the instrument and recommendations for its use as a tool to assess knowledge in engineering economy.     

Halifax Henna: The Art of Manageable Growth*

This case explores the dilemma many young women face when they begin a family: juggling a full‐time job as a young Chartered Professional Accountant (CPA) with a government job, continuing to grow a small business as a henna artist, and caring for a new baby. Even before the arrival of the first child, the combination of continuing to do both jobs was not sustainable. The case provides information to enable students to assess the financial health of a small business and provides a recommendation to the owner. In addition, information regarding paying childcare costs while continuing with a government job provides a realistic comparison for students. Often students jump to the money, which is currently in her accounting job, and forget that passion, dreams, and objectives for work–life balance, although earning less at the moment due to the part‐time nature, may be the best way forward.     

Speculative bubbles in the S&P 500: Was the tech bubble confined to the tech sector?

This study tests for the presence of periodically, partially collapsing speculative bubbles in the sector indices of the S&P 500 using a regime-switching approach. We also employ an augmented model that includes trading volume as a technical indicator to improve the ability of the model to time bubble collapses and to better capture the temporal variations in returns. We find that well over half of the S&P 500 index by market capitalization and seven of its ten sector component indices exhibited at least some bubble-like behavior over our sample period. Thus the speculative bubble that grew in the 1990s and subsequently collapsed was surprisingly pervasive in the US equity market and it affected numerous sectors including financials and general industrials, rather than being confined to information technology, telecommunications and the media. In addition, we develop a joint model for cross-sectional contagion of bubbles across the sectors and we examine whether there is evidence for bubble spillovers.     

Management Quality and Equity Issue Characteristics: A Comparison of SEOs and IPOs

We use hand-collected data on the management quality of firms making seasoned equity offerings (SEOs) or initial public offerings (IPOs) to analyze the relationship between management quality and equity issue characteristics, and to compare the effect of management quality on SEOs versus IPOs. We hypothesize that higher quality managers are more credible to equity market investors, thereby reducing the information asymmetry they face in the market and outsiders’ information production costs. Therefore, the equity issues of higher management quality firms will have more reputable underwriters, smaller underwriting spreads, and other expenses, and smaller SEO discounts. Further, since better managers will be able to select better projects, higher management quality firms will have larger offer sizes. Finally, since SEO firms are likely to suffer from less information asymmetry compared to IPO firms, these effects will be smaller for SEOs than for IPOs. Our findings support the above hypotheses. Our direct tests of the relationship between management quality and information asymmetry, and our comparison of information asymmetry in SEOs versus IPOs provide further support for these hypotheses.     

Fortune Favours the Bold? Exploring Tournament Behavior among Australian Superannuation Funds

In this paper we investigate the tournament induced risk-shifting behavior of Australian “multi-sector growth funds”. We apply a regression-based methodology and examine tournaments based on the calendar year and the financial year. In our core analysis we find evidence in favor of Taylor’s (J Econ Behav Organ 1455:1–11, 2003) risk shifting tournament hypothesis for financial year-end tournaments. Apart from the standard tournament hypothesis we also report a range of findings regarding stability; fund age; and fund size. Support for the Taylor hypothesis generally continues across these variations as well.

Transforming New Ideas into Practice: An Activity Based Perspective on the Institutionalization of Practices

We develop an activity‐focused process model of how new ideas can be transformed into front line practice by reviving attention to the importance of habitualization as a key component of institutionalization. In contrast to established models that explain how ideas diffuse or spread from one organization to another, we employ a micro‐level perspective to study the subsequent intra‐organizational processes through which these ideas are transformed into new workplace practices. We followed efforts to transform the organizationally accepted idea of ‘interdisciplinary teamwork’ into new everyday practices in four cases over a six year time period. We contribute to the literature by focusing on de‐habitualizing and re‐habitualizing behaviours that connect micro‐level actions with organizational level theorizing. Our model illuminates three phases that we propose are essential to creating and sustaining this connection: micro‐level theorizing, encouraging trying the new practices, and facilitating collective meaning‐making.     

The effect on stockholder wealth of product recalls and government action: The case of Toyota's accelerator pedal recall

We analyze the effect of Toyota's faulty accelerator pedal on stockholder wealth. Using the event study methodology, we show that a major recall in January of 2010 is associated with a 19% fall in the company's cumulative abnormal returns. Continued concerns that Toyota was unable to identify and adequately fix the problem prompted the National Highway Traffic Safety Administration to conduct its own investigation in March, 2010. The results of this government investigation exonerated the company and Toyota's cumulative abnormal returns rose by almost 9%. The Toyota case provides an opportunity to study a product recall with both company error and a government action that addressed concerns about the safety of the product.     

The Financial Effects of Uniform and Mixed Corporate Social Performance

Firms typically present a mixed picture of corporate social performance (CSP), with positive and negative indicators exhibited by the same firm. Thus, stakeholders' judgments of corporate social responsibility (CSR) typically evaluate positives in the context of negatives, and vice versa. Building on social judgment theory, we present two alternative accounts of how stakeholders respond to such complexity, which provide differing implications for the financial effects of CSP: reciprocal dampening and rewarding uniformity. Echoing notable findings on strategic consistency, our US panel study finds that firms that exhibit uniformly positive or uniformly negative indicators in particular dimensions of CSP outperform firms that exhibit a mixed picture of positives and negatives, which supports the notion that stakeholders' judgments of CSR reward uniformity.
