| The purpose of this study is to evaluate the economic and environmental impacts of planting energy crop on set-aside acreages in Taiwan. To do so, a Taiwan Agricultural Sector Model (TASM) was built and the data parameters of energy crop were incorporated into this model in order to simulate the economic and environmental impacts. Simulation results show that GHGE mitigation depends on the planting acreage of energy crops in which the optimal planting acreage of energy is determined by the profit of other agricultural products as well as government subsidy on energy crop. Therefore, the mitigation of GHGE depends on the government subsidy on energy crop per hectare. Such subsidy is also suitable for the green box by the regulation of WTO. |

| A general imperfect competition spatial equilibrium model is developed to estimate the trading country behaviors in the international rice market using a conjectural variation approach. Such a model allows the possibility of an imperfect competitive market to exit on both the export and import sides without any assumption of market structure. The empirical results show that the major exporting countries, Thailand, Vietnam, and the U.S. acted as high degree of imperfect competitors(or oligopolies) while Pakistan acted as a lower degree of imperfect competitor. The importing countries such as Japan, the Philippines, Europe, Brazil, and the former USSR behaved as high degree of imperfect competitors (or oligopsonies). The empirical results also show that... |

| The Kyoto Protocol represents the first international agreement to reduce greenhouse gas emissions. Proposed mitigation efforts may involve the agricultural sector through such options as planting trees, crop and livestock management changes, and biofuels production. The combined use of these strategies could substantially reduce net emissions of carbon dioxide, methane, and nitrous oxide. However, countries where the Protocol imposes emissions caps have expressed concern about their competitiveness with countries that are not part of the Kyoto Protocol. In a free-trade arena, food production and exports in unregulated countries could increase and reduce market share for the producers in complying countries. We examine the effects of differential Protocol... |

| Climate is the primary determinant of agricultural productivity. In many parts of the world, including the United States, one can trace much of the year-to-year variations in climate to the El Nino-Southern Oscillation phenomenon. In 1997-98 the world experienced a severe El event and this is being flowed by a strong 1998-99 La Nina. The work underlying this develops estimates of the economic consequences of these events on U.S. agriculture. Both phases result in economic damages -- a $1.5 to $1.7 billion loss for the El Nino and a $2.2 to $6.5 billion for La Nina. The major conclusion is that ENSO events do impose costs on agriculture and consumers. |

| The agricultural value of El Nino-Southern Oscillation (ENSO) phase knowledge is measured in a value-of-information framework using economic models. We examine the value of considering the full distribution of ENSO phase strength effects as opposed to average ENSO phase strength effects, as well as the implications of considering ENSO impacts on the rest of the world (ROW). A stochastic U.S. agricultural sector model linked with a global trade model is used to assess the value of ENSO phase information. When the full distribution of ENSO phase strength is considered, the value of phase information increases twofold with respect to the average ENSO effects. |

| This paper extends the existing theory on the equivalence of import tariff and quota. If the equivalence is defined on the domestic price level (weak equivalence), then either the zero conjectural variation for domestic country or a perfectly competitive market will be sufficient to support this equivalence. If the equivalence is defined both on the same domestic price level as well as tariff rate (strong equivalence), then the conditions are that either domestic country acts as a Cournot competitor and foreign country is a price taker, or both domestic and foreign country are price takers. An empirical spatial-equilibrium trade model is constructed to simulate the impacts of import tariff and quota. Using Taiwan¡¦s rice import as an example, the... |

| Trade liberalization and globalization has modernized the food retail sector in Taiwan, affecting consumers, producers and trade patterns. These changes have placed significant pressures on farmers and processors including more stringent quality control and product varieties. The government has launched a rice production-marketing contract program in 2005 to assist rice farmers and the agro-business sector to work together as partners. The minimum scale for each contract is 50 hectares of adjacent rice paddies with 50 participants including rice farmers, seedling providers, millers and marketing agents. In order to evaluate the outcome of this program, a survey is conducted in the summer of 2005 after the first (spring) crop is harvested. Information... |
