Excess Returns to R&D-Intensive Firms

Recent studies indicate that both current R&D investment levels and current or recent changes in R&D investment are positively associated with subsequent excess (risk-adjusted) stock returns. The tentative explanation offered for these results is that shares of R&D-intensive firms are mispriced because investors fail to see through earnings distortions caused by conservative accounting for R&D costs. However, an alternative explanation is that conventional controls for risk do not completely capture the riskiness of R&D-intensive firms, causing measured excess returns for these firms to be biased upward. This study provides evidence useful for distinguishing between the mispricing and risk explanations for R&D-related excess returns. Overall, our empirical results suggest that the positive association between R&D investment levels and excess returns is more likely to result from failure to control adequately for risk than from mispricing. On the other hand, our results do not rule out the possibility of a second source of excess returns that are due to mispricing and that are associated with changes in the level of R&D investment.     

Reducing the economic and human cost of layoffs

The deep recession of 1980–1982 caused many companies to face the prospect of large-scale work force reductions. Such cutbacks are costly for both the company and for the individuals affected. This article focuses on the outplacement efforts of the Ravenswood (West Virginia) Works of the Kaiser Aluminium & Chemical Corporation, using them as a model for organizing and managing similar programs.     

The impact of option listing on the price volatility and trading volume of underlying OTC stocks

This paper examines the impact of an initial option listing on the price volatility and trading volume of underlying OTC stocks. The sample is divided by market value to determine whether larger firms are impacted differently by option listing than smaller firms. We find relative trading volume increases significantly, with the small and medium market value firms showing the largest gain. However, the tests show no evidence of changes in price volatility following option listing. No significant changes were found in either the firms' betas or variance following option initiation. The results provide further evidence that option listing does not destabilize the market for the underlying stock.     

Profit-maximizing communities and the theory of local public expenditures: Comment

It is argued that Sonstelie and Portney's proof that property-value maximization by each local community leads to Pareto efficient supplies of public goods is incorrect. In their analysis, property-value maximization is equivalent to profit maximization by communities. They contend that less than maximum levels of profits would lead to lower utility levels for consumers. However, in their proof, Sonstelie and Portney do not correctly characterize the implications of utility maximization. When those implications are correctly stated, their proof no longer holds.     

Unemployment Invariance

Abstract. This paper provides a critique of the ‘unemployment invariance hypothesis’, according to which the behavior of the labor market, by itself, ensures that the long‐run unemployment rate is independent of the size of the capital stock, productivity and the labor force. In the context of an endogenous growth model, we show that the labor market alone need not contain all the equilibrating mechanisms to ensure unemployment invariance; in particular, other markets may perform part of the equilibrating process as well. By implication, policies that raise the growth path of capital or increase the effective working‐age population may influence the long‐run unemployment rate.

Schools as Self-Seeking Syndicates

Per capita school funding is a high-risk strategy. It would entrench the power of the schools as producers. Dr Dennis O'Keeffe of the Polytechnic of North London argues that schools must be responsive to the market.
