Summary. This paper compares the implications of short and long horizon planning in dynamic optimization problems with the structure of a standard one-sector growth model if agents have incomplete knowledge about the production function. Agents know the output and rate of return at the current capital stock and use an estimation of the production function based on this knowledge to determine current consumption. For standard utility functions without wealth-effects both long and short planning horizons yield convergence to the steady state - however at a faster rate than optimal -, or fluctuations around the steady state, and in both cases, long horizon planning yields a policy which locally at the steady state is closer to the optimal one than short horizon planning. On the other hand, for preferences with wealth effects where the intertemporal optimal path exhibits fluctuations, long horizon planning destabilizes the path and short horizon planning can generate paths which are qualitatively closer to the optimal one and yield higher discounted utility.Received: 5 April 2001, Revised: 15 September 2003, JEL Classification Numbers:

A bstract . Statisticians, students, teachers and even non statisticians can learn from a study of misuses of statistics. The practitioners can improve their use of statistical methods in research , the student can learn the correct method of analysis and the effects of incorrect analysis, the teacher can improve teaching and the non statistician can learn to evaluate statistical inputs to decision making All users of statistics, professional and nonprofessional, can benefit from the same examples. In this paper, the authors categorize misuses, by both the nature and effect of the misuse, and give examples for each category. 相似文献

Le Chatelier's Rule is in wide use for predicting the flammability of mixtures with multiple fuels present. The rule does not conveniently handle multiple inerts or elevated temperatures and pressures. This paper describes an alternate method, developed at Air Products, called FLAMCHEKTM, which conveniently handles these variables. This method for predicting flammability is based upon the commonality of the adiabatic flame temperature of a wide variety of fuels at their upper and lower flammable limits. The method, if PC based, can be extended to automatically control the addition of inerts, fuels, or oxidizers in order to avoid flammable conditions. The concept may be extended to more involved applications, such as within an oil well with fuel gas mixtures containing oxygen. In this case, the location from which a gas sample is obtained for analysis (wellhead) may have a different fuel analysis and flammability condition than the location where an explosion is likely to initiate (bottom of well). Hence a correction of the fuels analysis is required. 相似文献

This paper critically documents the rise of autonomy in subsidiary management literature, and develops an agenda for future research in this key area. Integrating and updating the seminal works of Paterson and Brock (2002) and Young and Tavares (2004), the paper begins with a critical review of subsidiary autonomy within the streams of subsidiary management literature. This leads to an assessment of the key contemporary issues requiring further investigation. These issues center around two key types of autonomy: assigned and assumed. We argue these types represent a more accurate, in-depth conceptualization of subsidiary autonomy, and also have significant implications for key related topics, including subsidiary development. This is depicted in an integrative model that draws upon agency theory, the network model of the MNE, the decision process perspective and the bundling model in presenting a revised view of subsidiary autonomy, and offers a basis for further research within the field. 相似文献

Abstract: We consider the impact of the May 1999 move to screen trading of the LIFFE FTSE 100 index futures contract. This resulted in a narrowing of the effective spread. Spread determinants are broadly similar in the two regimes. The narrowing of the spread appears due to increased competition among traders and a decline in tick-level volatility rather than to the way these or other variables affect the spread. Market depth appears largely unaffected. Under screen trading, realized spreads widen as more limit orders are taken up rather than in relation to order size per se . 相似文献

The authors identify three elements which will influence California's future. First, demographic shifts in the state's population have altered California's ethnic and cultural foundations. Second, the state educational system does not seem prepared to train larger numbers for information work, especially members of its growing ethnic population. Third, almost half the state's workforce is now employed in information-oriented work, whether in the industrial, service, or agricultural sectors. The authors demonstrate that the interaction of these elements has profound implications for California's development. 相似文献
