Contributing beyond the call of duty: examining the role of culture in fostering citizenship behavior and success in project-based work

Shifting goals, priorities and evolving customer demands require an exceptional effort, beyond the call of duty, on the part of employees to increase the likelihood for successful implementation of technologically driven projects. Our model posits that citizenship behavior, which captures individuals' behavior that goes above and beyond prescribed roles, effects project success and is influenced by the culture that exists in the project. We provide support for the model utilizing 222 participants in 71 product development, IT implementation and engineering projects, originating in firms from various industries in the United States using structural equation modeling. Owing to the constraints typically facing project managers, in terms of personnel availability and control over rewards, our findings suggest that project culture can be used by managers as an alternative lever to trigger employees' citizenship behavior, which in turn drives success. We provide valuable implications for individuals assigned to lead projects, who are concerned with aligning project culture with citizenship behavior, as part of their planning activities.     

Decentralized allocation of resources among many producers

We reconsider the question of allocating resources in large teams using decentralized procedures. Our assumption on the distribution of procedures is that it approximates a given undelying distribution in producers space; thus we relax prior approaches which utilize replicas or iid samplings. We examine when solving the allocation problem for the underlying distribution yields an appropriate solution to the specific sample. We then show how market- like mechanisms may be used to get a decentralized decision process which is asymptotically optimal.     

For the last time: stock options are an expense

Should stock options be recorded as an expense on a company's income statement and balance sheet, or should they remain where they are, relegated to footnotes? The extraordinary boom in share prices during the Internet bubble made critics of option expensing look like spoilsports. But since the crash, the debate has returned with a vengeance. And no wonder: The authors believe the case for expensing options is overwhelming. In this article, Nobel Iaureate Robert Merton, one of the inventors of the Black-Scholes option-pricing model; his coauthor on the classic textbook Finance, Zvi Bodie; and Robert Kaplan, creator of the Balanced Scorecard, examine and dismiss the principal claims put forward by those who continue to oppose options expensing. They demonstrate that stock-option grants do indeed have real cash-flow implications that need to be reported. They show that effective ways certainly exist to quantify those implications. They detail the distortions that relegating stock-option accounting to footnotes creates. And they show why reporting option costs should in no way hamper young companies in their efforts to provide incentives. Options are indeed a powerful incentive, the authors agree, and failing to record a transaction that creates such powerful effects is economically indefensible. Worse, it encourages companies to favor options over alternative incentive systems. It is not the proper role of accounting standards, the authors argue, to distort executive and employee compensation by subsidizing one particular form of compensation and no other. Companies should choose compensation methods according to their economic benefits--not the way they are reported.     

Labor supply flexibility and portfolio choice in a life cycle model

This paper examines the effect of the labor-leisure choice on portfolio and consumption decisions over an individual's life cycle. The model incorporates the fact that individuals may have considerable flexibility in varying their work effort (including their choice of when to retire). Given this flexibility, the individual simultaneously determines optimal levels of current consumption, labor effort, and an optimal financial investment strategy at each point in his life cycle. We show that labor and investment choices are intimately related. The ability to vary labor supply ex post induces the individual to assume greater risks in his investment portfolio ex ante.     

The sharpest tool in the shed: IPO financial statement management of STEM vs. non-STEM firms

The valuation of STEM (science, technology, engineering, and math) firms has recently gained attention in the literature. Research has shown that, for valuation of STEM firms, accounting items such as sales growth and R&D expenditures matter more than bottom-line earnings. We examine whether, around the time of the IPO, STEM managers apply discretion over the accounting items most weighted by investors for their valuation. We find that investors tend to weigh sales growth and R&D more heavily than earnings in valuing STEM firms and that managers respond by managing those items rather than bottom-line earnings as in prior research. We find that future stock returns of STEM firms are negatively associated with sales management and not with abnormal accruals as for non-STEM firms. Our results illuminate the differential behavior of STEM managers and highlight the importance of a departure from the traditional IPO earnings management paradigm, which assumes that firms mainly manage their earnings.     

The inconsistency of common scale estimators when output prices are unobserved and endogenous

This paper explores the inconsistency of common scale estimators when output is proxied by deflated sales, based on a common output deflator across firms. The problem arises when firms operate in an imperfectly competitive environment and prices differ between them. In particular, we show that this problem reveals itself as a downward bias in the scale estimates obtained from production function regressions, under a variety of assumptions about the pattern of technology, demand and factor price shocks. The result also holds for scale estimates obtained from cost functions. The analysis is carried one step further by adding a model of product demand. Within this augmented model we examine the probability limit of the scale estimate obtained from an ordinary production function regression. This analysis reveals that the OLS estimate will be biased towards a value below one, and how this bias is affected by the magnitude of the parameters and the amount of variation in the various shocks. We have included an empirical section which illustrates the issues. The empirical analysis presents a tentative approach to solve the problem discussed in the theoretical part of this paper.     

Empirical Patterns of Firm Growth and R&D Investment: a Quality Ladder Model Interpretation

We present a partial equilibrium model of endogenous firm growth with R&D investment and stochastic innovation as the engines of growth, drawing on the quality ladder models in the macro growth literature, and the literature on patent races and the discrete choice models of product differentiation. The model fits a number of empirical patterns well, including: (i) a skewed size distribution of firms with persistent differences in firm sizes, (ii) firm growth independent of firm size, as stated in the so-called Gibrat's law, and (iii) R&D investment proportional to sales.
