Structural changes in U.S. agriculture: Implications for African American farmers

Structural changes in U.S. agriculture, influenced by technological and institutional forces, have altered the economic and social characteristics of rural America, especially that segment of rural America populated by farmers and their families. Changes in the structure of agriculture have greater implications for small scale farmers, many of whom are African American, in that strategic options for their farm-firms are constrained to: increasing their farm size, exiting farming, and obtaining off-farm employment to survive. This article presents a rationale for public support of limited resource farmers, identifies structural trends in U.S. agriculture and their impacts on African American farmers, discusses economic problems unique to these farmers, and recommends needs for specific public policies and development programs.     

Decision Usefulness of Cash and Accrual Information: Public Sector Managers’ Perceptions

This study examines the usefulness of accrual accounting information for internal decision‐making contexts in the Western Australian public sector. Based on questionnaire responses of public sector managers, it was found that accrual accounting is perceived to be more useful than cash accounting in 16 of the 19 decision situations. These results suggest that the perceived usefulness of the accrual accounting system has improved with the passage of time. It may well be that perceptions of the usefulness of information derived from an accounting system will change over time as users gain familiarity and experience with a system.     

Risk Management,Corporate Governance,and the Search for Long-Term Investors

This discussion explores a number of ways that more effective risk management, corporate governance, and communication with investors can help companies increase their effciency and long-run value. According to one of the panelists, recent surveys of corporate directors suggest that companies should devote more time and attention to three issues—strategy, risk management, and succession planning—and that strategy and risk are the “flipsides of the same coin.” As the panelist argues, “You can't talk about strategy without talking about what risks you're going to take—and what risks you decide to take has to depend on the core competencies that drive the corporate strategy.” In addition to making risk management a critical part of corporate strategy, another notable recommendation is to communicate a company's strategy and business plan as clearly as possible to investors, with the aim of attracting more sophisticated, long-term shareholders. Contrary to popular belief, such a group may well include some hedge funds and other activist shareholders. According to a newly released report on shareholder activism (produced and cited by another panelist), corporate boards should work harder to identify and engage the “largest 10 shareholders in the organization,” with the ultimate goal of cultivating a shareholder base that buys into the company's strategy.     

Optimal asset allocation for a large number of investment opportunities

This paper introduces a stock‐picking algorithm that can be used to perform an optimal asset allocation for a large number of investment opportunities. The allocation scheme is based upon the idea of causal risk. Instead of referring to the volatility of the assets time series, the stock‐picking algorithm determines the risk exposure of the portfolio by concerning the non‐forecastability of the assets. The underlying expected return forecasts are based on time‐delay recurrent error correction neural networks, which utilize the last model error as an auxiliary input to evaluate their own misspecification. We demonstrate the profitability of our stock‐picking approach by constructing portfolios from 68 different assets of the German stock market. It turns out that our approach is superior to a preset benchmark portfolio. Copyright © 2005 John Wiley & Sons, Ltd.     

Money demand in the euro area: new insights from disaggregated data

Conventional money demand specifications in the euro area have become unstable since 2001. We specify a money demand equation in deviations of individual euro area Member States variables from the euro area average and show that the income elasticity as well as the interest rate semi-elasticity remain stable. The corresponding deep parameters of the utility function have not changed fundamentally. Aggregate money demand instability does therefore not result from altered standard factors determining the preference for holding money. Instead, other factors determine the aggregate monetary overhang. Since monetary developments cannot easily be explained by changing preferences, they should be closely monitored as they may actually be a sign of other factors.
