Technological diversity,related diversification,and firm performance

Previous findings that related diversification creates value have been called into question over concerns about methodology and measures. Reviewing existing theory to consider how a firm's knowledge base interacts with its product market activity, I address several of these concerns by creating a measure of technological diversity based on citation‐weighted patents. The measure indicates a firm's opportunity for corporate diversification based on economies of scope in valuable knowledge assets, is defined for both single‐ and multibusiness firms, and is not correlated with more fundamental aspects of diversification, such as the number of businesses in the corporate portfolio. Evidence from a large sample of firms shows the positive relationship between diversification based on technological diversity and market‐based measures of performance, controlling for R&D intensity and capital intensity as further indicators of the type of assets underlying diversification. Results hold when controlling for the endogeneity of diversification and performance in a cross‐sectional sample or when controlling for unobserved factors using panel data.

Employee Stock Options, Corporate Taxes, and Debt Policy

We find that employee stock option deductions lead to large aggregate tax savings for Nasdaq 100 and S&P 100 firms and also affect corporate marginal tax rates. For Nasdaq firms, including the effect of options reduces the estimated median marginal tax rate from 31% to 5%. For S&P firms, in contrast, option deductions do not affect marginal tax rates to a large degree. Our evidence suggests that option deductions are important nondebt tax shields and that option deductions substitute for interest deductions in corporate capital structure decisions, explaining in part why some firms use so little debt.     

Making tax and social security decisions: lean and deskilling in the UK Civil Service

Lean working has had a significant impact on the work skills of civil servants. This study examines the impact of lean specifically focusing on ‘decision‐makers’, those civil servants engaged in deciding tax and social security claims. Using qualitative data from trade union members and stewards in two major government departments, this study found significant evidence of deskilling often in the face of dealing with potentially complex legal and factual issues. Using Mashaw's framework of administrative justice, the article argues that management's use of lean was evidence of an accelerated shift to a managerial model of administering tax and benefits where the administrative processes of decision‐making become paramount at the expense of the quality of the decisions made.     

Crossing the Boundaries of Obligation: Are Corporate Salaries a Form of Bribery?

Trans-National Corporations (TNCs) pay relatively high salaries to local people in host countries. TNCs assume that such employees will accept an employeeÇôemployer relationship similar to that which exists in North America, but the obligations and personal interests that such a relationship create often directly conflict with systems of obligation already established in the host country. When TNCs do business across the boundaries of systems of obligation, corporate salaries can be seen as a form of unethical bribery. In this paper, the core case of business bribery is described consistent with the usual philosophical analysis of bribery, and the grounds for thinking bribery is unethical are made clear. The amount of a bribe is irrelevant to the ethical analysis. Bribery is distinguished from tips and grease on structural grounds. The concept of a system of obligation is defined, and examples given that show the variability of systems of obligation in host countries. Arguments are given to show that salaries paid by TNCs create obligations and personal interests which sometimes conflict with existing systems of obligation, and that such payments have the same structure as more traditional forms of bribery. The ethical issues of corporations crossing the boundaries of systems of obligations are discussed.     

CROSS-PRODUCT SPILLOVERS IN THE SEMICONDUCTOR INDUSTRY: IMPLICATIONS FOR STRATEGIC TRADE POLICY

Although the manufacture of semiconductor products has been alleged to create substantial benefits to the economy resulting from the spillover of knowledge, this claim, with the exception of Irwin and Klenow (1994a), has not been subjected substantially to empirical analysis. Our article extends the analysis of Irwin and Klenow and develops and tests a model of knowledge spillovers across several semiconductor memory products. The results indicate that cross-product spillovers from Dynamic Random Access Memories (DRAMs) the integrated circuit product often designated as a "technology driver" to other memory products were limited. We discuss the implications of these results for strategic trade policy.     

Casino Revenues and Retail Property Values: The Detroit Case

We analyze the effects of commercial casinos on retail property values in the Detroit urban area. Accounting for property characteristics and proximity to the casinos, casinos are found to have a significantly positive influence on retail property values. The effect is stronger within a 5-mile radius of the casinos, suggesting that casinos have a complementary, rather than substitution, effect on other businesses. This provides some of the first micro-level empirical evidence to support the “drawing power” of casinos and the impact of consumer spending on surrounding businesses. The model developed and tested in this study can be applied to other casino jurisdictions to gain further evidence on the impact of commercial casinos.
