R&D management through network mapping: using the Internet to identify strategic network actors in cooperative research networks

Most R&D management techniques to date have emphasized the immediate organizational context or the internal structure and process of the R&D project. Recently however attempts have been made at situating R&D management in a wider context of inter‐organizational R&D activities. This paper presents the technique of R&D network mapping as a means of providing strategic intelligence to the R&D manager. The paper backgrounds this technique with a discussion of the general issue and significance of R&D networks. A methodology for R&D network mapping is then exemplified by outlining how a network database of cooperating projects and institutes in the telecom research sector was built by utilizing the World Wide Web. Finally a number of suggestions are made as to how and when network mapping should be applied in strategic R&D management.     

Accrual usage to manage earnings toward financial analysts' forecasts

This study examines whether management uses discretionary accounting accruals to move earnings upward toward analysts' earnings forecasts when it appears that earnings before discretionary accruals will fall short of the forecast. An earnings shortfall relative to analysts' forecasts could lead management to fear lower compensation and an increase in the likelihood of job termination. The article finds that firms whose earnings before discretionary accruals are below analysts' forecasts use income-increasing discretionary accruals and do so to a greater extent than do firms whose earnings before discretionary accruals are above analysts' forecasts.     

New developments in east-west economic relations

The past four years have witnessed a marked increase in the economic activity between East and West. The volume of foreign trade rose strongly; but as Eastern exports showed only slight increases while their imports from the West went up by leaps and bounds, the deficits of the Comecon countries became ever greater — an imbalance which has given rise to a number of problems.

Judicial Reform

A review of the evidence on judicial reform across countriesshows that those seeking to improve economic performance shouldnot focus on judicial efficiency alone but on independence aswell. It also shows that the level of resources poured intothe judicial system and the accessibility of the system havelittle impact on judicial performance. Most of the problem ofjudicial stagnation stems from inadequate incentives and overlycomplicated procedures. Incentive-oriented reforms that seekto increase accountability, competition, and choice seem tobe the most effective in tackling the problem. But incentivesalone do not correct systematic judicial failure. Chronic judicialstagnation calls for simplifying procedures and increasing theirflexibility.      

Contingency Fees, Settlement Delay, and Low-Quality Litigation: Empirical Evidence from Two Datasets

Although flat fees are common for divorces, wills and trusts,and probate, lawyers in personal injury cases generally arepaid by contingency fee or at an hourly rate. Arguments havebeen made that contingency fees increase low-quality, "frivolous"litigation but counterarguments suggest that contingency feesactually limit such litigation and instead it is hourly feesthat increase low-quality litigation. Using a difference indifferences test and data on a cross section of states in 1992,we test whether legal quality is lower under contingency orhourly fees. We also examine medical malpractice claims in Floridausing a time series centered around a law change that limitedcontingency fees. We also examine the impact of fee arrangementson the expected time to settlement. We find that hourly feesencourage the filing of low-quality suits and increase the timeto settlement (i.e., contingency fees increase legal qualityand decrease the time to settlement).     

New guidelines from the National Cholesterol Education Program: what is the impact on risk assessment?

The National Cholesterol Education Program has developed a set of guidelines for optimal levels of serum lipids that are recommended to reduce the risk of coronary artery disease. This article compares those values to lipid levels found in insurance applicants.     

An Impact Evaluation of Education, Health, and Water Supply Investments by the Bolivian Social Investment Fund

This article reviews the results of an impact evaluation ofsmall-scale rural infrastructure projects in health, water,and education financed by the Bolivian Social Investment Fund.The impact evaluation used panel data on project beneficiariesand control or comparison groups and applied several evaluationmethodologies. An experimental design based on randomizationof the offer to participate in a social fund project was successfulin estimating impact when combined with bounds estimates toaddress noncompliance issues. Propensity score matching wasapplied to baseline data to reduce observable preprogram differencesbetween treatment and comparison groups. Results for educationprojects suggest that although they improved school infrastructure,they had little impact on education outcomes. In contrast, interventionsin health clinics, perhaps because they went beyond simply improvinginfrastructure, raised utilization rates and were associatedwith substantial declines in under-age-five mortality. Investmentsin small community water systems had no major impact on waterquality until combined with community-level training, thoughthey did increase the access to and the quantity of water. Thisincrease in quantity appears to have been sufficient to generatedeclines in under-age-five mortality similar in size to thoseassociated with the health interventions.     

Gender, Time Use, and Change: The Impact of the Cut Flower Industry in Ecuador

This article uses survey data from Ecuador to examine the effectsof women's employment on the allocation of paid and unpaid laborwithin the household. I compare a region with high demand forfemale labor with a similar region in which demand for femalelabor is low. The comparison suggests that market labor opportunitiesfor women have no effect on women's total time in labor butincrease men's time in unpaid labor. The increase in men's timein unpaid work reflects women's increased bargaining power inthe home.     

Normal mixture diffusion with uncertain volatility: Modelling short- and long-term smile effects

This paper introduces a parameterization of the normal mixture diffusion (NMD) local volatility model that captures only a short-term smile effect, and then extends the model so that it also captures a long-term smile effect. We focus on the ‘binomial’ NMD parameterization, so-called because it is based on simple and intuitive assumptions that imply the mixing law for the normal mixture log price density is binomial. With more than two possible states for volatility, the general parameterization is related to the multinomial mixing law. In this parsimonious class of complete market models, option pricing and hedging is straightforward since model prices and deltas are simple weighted averages of Black–Scholes prices and deltas. But they only capture a short-term smile effect, where leptokurtosis in the log price density decreases with term, in accordance with the ‘stylised facts’ of econometric analysis on ex-post returns of different frequencies and the central limit theorem. However, the last part of the paper shows that longer term smile effects that arise from uncertainty in the local volatility surface can be modeled by a natural extension of the binomial NMD parameterization. Results are illustrated by calibrating the model to several Euro–US dollar currency option smile surfaces.
