R&D spillovers and the case for industrial policy in an open economy

In this paper we consider the case for subsidies towards firmswhich generate R&D spillovers in open economies. We showthat in the presence of strategic behaviour by firms many expectedresults are overturned. Local R&D spillovers to other domesticfirms may justify an R&D tax rather than a subsidy; R&Dcooperation by local firms over-internalises the externalityand also justifies an R&D tax; and international spilloverswhich benefit foreign firms may justify a subsidy, even thoughthe government cares only about the profits of home firms.     

WATER BANKING AND RESTORATION OF ENDANGERED SPECIES HABITAT: AN APPLICATION TO THE SNAKE RIVER

Most river basins have experienced development of water projects to promote flood control, recreation, and hydropower and agricultural production. Though the projects helped establish stable economies, there have been adverse impacts to the natural environment and wildlife that reside in these river basins. One of the key policy tools for habitat restoration is management of instream flows. Alternative water banking policies for restoring habitat are compared using a spatial optimization model to identify which policies work best to augment instream flows for habitat restoration. Results indicate that policy goals dictate what type of water bank is preferred.     

A new estimate of transaction costs

Transaction costs are important for a host of empirical analysesfrom market efficiency to international market research. Buttransaction costs estimates are not always available, or whereavailable, are cumbersome to use and expensive to purchase.We present a model that requires only the time series of dailysecurity returns to endogenously estimate the effective transactioncosts for any firm, exchange, or time period. The feature ofthe data that allows for the estimation of transaction costsis the incidence of zero returns. Incorporating zero returnsin the return-generating process, the model provides continuousestimates of average round-trip transaction costs from 1963to 1990 that are 1.2% and 10.3% for large and small decile firms,respectively. These estimates are highly correlated (85%), withthe most commonly used transaction cost estimators.     

The case of the hidden harassment

The past year has seen a growing public awareness of sexual harassment in the workplace. The question of what constitutes sexual harassment and how to recognize it has been debated in the news, the courts, and Congress. This HBR case study is less concerned with defining it than with examining what a manager should do about it. When Filmore Trust manager Jerry Tarkwell found out one of his employees was being sexually harassed on the job, he thought he knew exactly what to do. Following company policy, he immediately notified the bank's equal employment office. Then he called Jill McNair, the employee being harassed. Her response dumbfounded him. "You had no right to call EEO before talking to me," McNair said angrily. Do you have any idea what could happen to me and to my career if people find out about this?" Tarkwell didn't understand; McNair wasn't to blame. He believed the only person who should be worried was the harasser. Tarkwell tried to spell out the procedure for her. "All you have to do is write a letter and ..." McNair cut him off. "If this gets investigated by EEO, everyone in the building could be questioned. I'll probably get transferred, and then I won't have a chance at promotion. And who'd want to work with me? Every man in the company would be afraid I'd report him if he so much as opened a door for me."(ABSTRACT TRUNCATED AT 250 WORDS)     

The use of foreign currency derivatives and firm market value

This article examines the use of foreign currency derivatives(FCDs) in a sample of 720 large U.S. nonfinancial firms between1990 and 1995 and its potential impact on firm value. UsingTobin's Q as a proxy for firm value, we find a positive relationbetween firm value and the use of FCDs. The hedging premiumis statistically and economically significant for firms withexposure to exchange rates and is on average 4.87% of firm value.We also find some evidence consistent with the hypothesis thathedging causes an increase in firm value.
