A Cross‐national Comparison of R&D Expenditure Decisions: Tax Incentives and Financial Constraints*

We provide evidence on the impact of tax incentives and financial constraints on corporate R&D expenditure decisions. We contribute to extant research by comparing R&D expenditures in the United States and Canada, thereby exploiting the differences in the two countries' R&D tax credit mechanisms and generally accepted accounting principles. The two tax incentive mechanism designs are consistent with differing views of the degree of financial constraints faced by firms in these economies. Our sample also allows us to explore the effects of capitalizing R&D on Canadian firms. Employing a matched design, we document relations between tax credit incentives and R&D spending consistent with both Canadian and U.S. public companies responding as though they are not financially constrained. We estimate that the Canadian credit system induces, on average, $1.30 of additional R&D spending per dollar of taxes forgone while the U.S. system induces, on average, $2.96 of additional spending. We also find that firms that capitalize R&D costs in Canada spend, on average, 18 percent more on R&D. Collectively, this evidence is important to the ongoing debates in both countries concerning the appropriate design of incentives for R&D and is consistent with the assumptions found in the U.S. tax credit system, but not those found in the Canadian system.     

Gender Differences in the Returns to and the Acquisition of On-the-Job Training

This article finds that gender differences in on-the-job training significantly affect the male/female wage gap. First, we find that previously trained workers exhibit larger cumulative wage gains during their current training. Thus, a substantial portion of the gender wage gap results from the fact that women have little prior training relative to men. Second, a significant amount of the observed male/female wage differential is explained by less female acquisition of current training. Gender differences in workplace promotion and training practices help explain why women accumulate less training than men. Both of these sources of gender differences have lessened from 1976 to 1985, which has led to a narrowing of the male/female wage gap.     

The Interaction between Internal Control Assessment and Substantive Testing in Audits for Fraud*

We examine the interaction between internal control assessments and substantive testing in a model of fraud detection. The purpose of our study is to examine a two‐stage model of the auditor‐manager interaction in which the auditor assesses the “likelihood” or possibility of fraud in the first stage and conducts substantive tests in the second stage. We examine the allocation of audit resources across these two distinct facets of the audit. We find that, regardless of the auditor's allocation, the probability of undetected fraud remains the same, but the allocation of some audit resources to internal control assessment may provide cost savings for the auditor.     

The New Game in Town: Competitive Effects of IPOs

We analyze the effect of initial public offerings (IPOs) on industry competitors and provide evidence that companies experience negative stock price reactions to completed IPOs in their industry and positive stock price reactions to their withdrawal. Following a successful IPO in their industry, they show significant deterioration in their operating performance. These results are consistent with the existence of IPO‐related competitive advantages through the loosening of financial constraints, financial intermediary certification, and the presence of knowledge capital. These aspects of competitiveness are significant in explaining the cross‐section of underperformance as well as survival probabilities for competing firms.     

Applications of Optimal Stopping in Resource Economics*

Some applications of optimal stopping rules in the analysis of resource economic problems are surveyed. The conceptual foundation for the approach stems from the dual roles of uncertainty and irreversibility in these problems. A stochastic adaptation of Wicksell's ‘tree-cutting’ paradigm is exposited and shown to provide a rigorous methodology that is as intuitive as more familiar contingent-asset approaches. Four resource economic applications are considered: environmental problems, urban development, bioeconomic harvesting and resource project timing and valuation.     

Short‐Selling Risk

Short sellers face unique risks, such as the risk that stock loans become expensive and the risk that stock loans are recalled. We show that short‐selling risk affects prices among the cross‐section of stocks. Stocks with more short‐selling risk have lower returns, less price efficiency, and less short selling.     

Vote Trading and Information Aggregation

The standard analysis of corporate governance assumes that shareholders vote in ratios that firms choose, such as one share‐one vote. However, if the cost of unbundling and trading votes is sufficiently low, then shareholders choose the ratios. We document an active market for votes within the U.S. equity loan market, where the average vote sells for zero. We hypothesize that asymmetric information motivates the vote trade and find support in the cross section. More trading occurs for higher‐spread and worse‐performing firms, especially when voting is close. Vote trading corresponds to support for shareholder proposals and opposition to management proposals.
