Navigating in the Midst of More Uncertainty and Risk

With the steady increase in the variety and scale of uncertainties and risks, the challenges for today's executives have become ever more complex and daunting. One powerful tool for navigating among different risks and uncertainties is scenario planning. From its early days of use within Shell, scenario planning has evolved in ways that make it better suited to the tasks of identifying, analyzing, and managing various financial risks across different industries. During the last ten years, Morgan Stanley has also been using scenario planning to gain a better understanding of key risks and uncertainties facing the financial services industry, ranging from the consequences of possible changes in the dollar to the emergence of hedge funds and the remarkable growth of China and India. In discussing the benefits of scenario planning, the authors note its potential to help management in a number of ways:

• ? By challenging conventional thinking and current assumptions about its industry and world;
• ? By identifying key signals or potential direction changes ahead of time, which is especially important when lead times to invest, hedge, or change assets are limiting factors;
• ? By identifying and assessing the value of strategic or “real” options—options to invest in new opportunities or limit downside risks that may suddenly open up or disappear, and that man‐ agement must be prepared to “exercise” quickly and decisively;
• ? By reinforcing the recognition that value added comes not just from better strategic thinking and planning, but from the role of risk management in helping companies take advantage of new opportunities;
• ? By encouraging more cross‐divisional and firm‐wide conversations about strategic choices and options, thereby creating a shared understanding of and greater consensus about chosen strategies; and
• ? By forcing them to go beyond the limits of typical three‐to‐five year forecasting limitations to think hard about longer‐term strategic choices.

     

Performance Measurement of the Agricultural Marketing Cooperatives: The Gap between Theory and Practice

The performance of agricultural cooperatives depends on their business objectives, which are defined in different ways in the literature. We review the theoretical literature on the performance of agricultural marketing cooperatives. Studies can be divided into two classes, those that assume a single objective and those that assume multiple objectives. This classification integrates three views of the cooperatives: ( a ) vertical integration of firms, ( b ) independent enterprise, and ( c ) coalition of firms. Empirical studies on the financial performance of cooperatives are classified into two categories, studies based on the economic theory of the firm and studies that emphasize accounting techniques. Empirical studies have failed to address the cooperatives' objectives as represented by the theoretical literature on cooperative performance.     

Equilibrium Search with Continuous Productivity Dispersion: Theory and Nonparametric Estimation

In this article we develop an equilibrium search model with a continuous distribution of firm productivity types within a given labor market. We characterize equilibrium, derive expressions for the endogenous equilibrium wage distributions, and characterize the set of wage distributions that can be generated by the model. We develop a structural nonparametric estimation method for the productivity distribution. We estimate the model using French longitudinal survey data on labor supply, and we compare the results with those from a French panel data set of firms. The results are informative on the degree to which firms exploit search frictions.     

The Role of Long-Term Finance: Theory and Evidence

Improving the supply of long-term credit to industrial firmsis considered a priority for growth in developing countries.A World Bank multicountry study looks at whether a long-termcredit shortage exists and, if so, whether it has had an impacton investment, productivity, and growth. The study finds thateven after controlling for the characteristics of individualfirms,businesses in developing countries use significantly less long-termdebt than their counterparts in industrial countries. Researchersare able to explain the difference in debt composition betweenindustrial and developing countries by firm characteristics;by macroeconomic factors; and, most importantly, by financialdevelopment, government subsidies, and legal and institutionalfactors. The analysis concludes that long-term finance tends to be associatedwith higher productivity. An active stock market and an abilityto enter into long-term contracts also allow firms to grow atfaster rates than they could attain by relying on internal sourcesof funads and short-term credit alone. Importantly, althoughgovernment-subsidized credit markets have increased the long-termindebtedness of firms, there is no evidence that these subsidiesare associated with the ability of firms to grow faster. Indeed,in some cases subsidies are associated with lower productivity.      

External Costs of Aquaculture Production in West Virginia

Temperate hill-lands of the U.S.A. such as those in West Virginia are areas from which increasing output of farm-raised fish may be possible. However, the downstream economic impacts of current and projected future effluent as a result of aquaculture production have not been extensively studied. Using an externality framework and a combination of primary and secondary data, this study determines pollution prevention costs (PPC), and downstream pollution damage costs resulting from fish farm wastewater effluent measured as willingness to pay (WTP) for restoring water quality. PPC is estimated at $0.11 per kg of trout produced (which would add 6% to private production cost), and WTP is estimated at $0.49 per kg of trout produced (representing 25% of private production cost) at current production and price levels. This study shows that installation of filtration units is a low-cost (less than 6% of total cost) and an effective technology for controlling pollution at the source. Internalizing external costs (adding this 6% to private production costs) is one strategy that could contribute to sustainable growth of the aquaculture industry.     

The anatomy of unemployment dynamics

This paper examines the relation between individual unemployment durations and incidence (inflow size) on the one hand and the time-varying macroeconomic conditions in the economy on the other. We develop a model for the analysis of aggregate unemployment incidence and duration data and estimate this model on quarterly French data over the period 1982-1994 stratified by sex. We find upward trends in both incidence and durations. The former is relatively important for females, the latter for males. Male incidence and durations are countercyclical, with only a minor role for cohort effects on durations. In contrast, female cohorts entering at the top of the cycle have relatively short unemployment spells and the female incidence is, if anything, procyclical. There is strong seasonal variation, in particular in the incidence. Finally, we find relatively small non-monotonic individual duration dependence in the first six quarters of unemployment. Unobserved heterogeneity explains the observed negative duration dependence at these durations. We provide some evidence that negative individual duration dependence, and not heterogeneity, is important at higher durations.
