| This study investigates the effects of class size, high school accounting, aptitude and attitude on learning , measured by the difference between post-test and pre-test scores, in an undergraduate financial accounting class, after controlling for students' major and semester level. Statistical analysis showed that scores of students in small classes improved by 48%, while scores of students in the large classes improved by 6% percent, implying a decline in learning by 88% by shifting to larger classes. High school accounting was found to improve pre- and post-test scores but the improvement on their post-test scores was significantly lower, implying a diminishing effect of high school accounting on performance as the complexity of the course material... |

| The number of small commodity livestock slaughter plants in the Upper Northern Plains region continues to decline. Significant factors contributing to this decline include: 1) pressure to consolidate, thereby capturing economies of scale; 2) relatively stringent federal inspection specifications, along with; 3) HACCP (Hazardous Analysis Critical Control Points) requirements. At the same time, consumer demand (markets) for specialty, selected, and exotic meats appears to be growing. For example, the recent market successes in Europe evidenced by the North American Bison Cooperative based in New Rockford, North Dakota. Several alternative livestock producer groups have emerged which include lamb, ratite, elk, deer, goat, poultry, rabbit, specialty beef,... |

| The effect of sampling error in estimation of farmers' mean yields for crop insurance purposes is explored using farm-level corn yield data in Iowa from 1990 to 2000 and Monte Carlo simulations. We find that sampling error combined with nonlinearities in the insurance indemnity function will result in empirically estimated crop insurance rates that exceed actuarially fair values by between 2 and 16 percent, depending on the coverage level and the number of observations used to estimate mean yields. Accounting for the adverse selection caused by sampling error results in crop insurance rates that will exceed fair values by between 42 and 127 percent. We propose a new estimator for mean yields based on a common decomposition of farm yields into systemic and... |

| In general, reported rates of return to agricultural R&D are high, but questions have been raised about upward biases in the evidence. Among the reasons for this bias, insufficient attention to attribution aspects-matching of research benefits and costs-is a pervasive problem, the magnitude of which is illustrated here with new evidence for Brazil. Over the period 1981 to 2003, varietal improvements in upland rice, edible beans, and soybeans yielded benefits attributable to research of $14.8 billion in present value (1999 prices) terms; 6.1 percent of the corresponding value of crop output. If all of those benefits were attributed to Embrapa, a public research corporation accounting for more than half Brazil's agricultural R&D spending, the... |

| In literature, impact estimates of agricultural biotechnology vary strongly according to the region, the crop, the year, the scale, and the methodology of the study. Therefore, this paper provides a methodological background for analysing, interpreting, and comparing these estimates. All possible uncertainties entailed in the estimation procedure are reviewed as well as a methodology to incorporate them into a stochastic simulation model. This procedure can be used to assess the welfare effects of agricultural biotechnology in the European Union. |

| This paper aims to articulate aspects of the Private Sector Development Strategies of two key Development Banks in order to reflect on commonalities and differences. The paper reviews these strategies and focuses on what is included and what is omitted, as well as commenting on the characteristics of these strategies as corporate direction setting. The degree to which strategies seem to have incorporated organisational learning, power relationships and cultural contexts is then assessed. |

| The paper analyzes the changes in agricultural trade patterns in Slovakia that occured during the gradual trade liberalization due to European Union enlargement in 2004. The results indicate that approximately 30% of the increase in agricultural imports from the EU15 and CEECs between 2000 and 2005 was due to the discriminatory trade liberalization between Slovakia and the EU15 and CEECs, i.e. due to the formation of a customs union. Part of the increase in agricultural trade with the EU15 and CEECs was at the expense of trade with more efficient producers from the rest of the world, i.e. there is an indication that some trade diversion could have occurred. The second wave of agricultural trade liberalization (from 2002 onward) brought about greater... |

| The Asian Development Bank has sponsored research on market-based instruments for managing pollution in Metro Manila, Philippines, where air quality is seriously degraded. This report offers three policy options for reducing particulate emissions and their precursors. For stationary sources, we recommend an emissions fee that creates efficient financial incentives to reduce emissions while raising revenues for monitoring and enforcement activities. For mobile sources, we propose a pilot diesel retrofit program using a low-cost technology that is effective at existing 2,000 ppm sulfur content. Second, we recommend a charge on the sulfur content of diesel fuel to encourage meeting and surpassing the 500 ppm standard to allow for more advanced particulate... |

| The Kyoto Protocol sets legally binding emission targets for industrialized countries without accounting for reductions carried out prior to 2008, the beginning of the first commitment period. There exists only one exception, the project-based Clean Development Mechanism. Two other possible ways to allow crediting for early reductions are discussed in this paper, a domestic scheme and early Joint Implementation. The implications of these concepts are analyzed on a macro as well as on a micro level taking the domestic and international commitments into account. They can lead to a strong redistribution and are prone to free riding. We conclude that early crediting makes built on clear baselines, sets incentives for innovation and provides for institutional... |
