AN ANALYSIS OF TOTAL FACTOR PRODUCTIVITY GROWTH IN CHINA'S AGRICULTURAL SECTOR AgEcon
Hsu, Shih-Hsun; Yu, Ming-Miin; Chang, Ching-Cheng.
A panel data of 27 provinces in China is used to analyze the productivity growth in China's agricultural sector over the period 1984-1999. We first compute the output-orientated Malmquist productivity indexes and its decompositions using non-parametric DEA (Data Envelopment Analysis) approach. Tobit regressions are then used to identify the major determinants of TFP growth and its components.

An Economy-wide Analysis of Impacts on Taiwan of Reducing Tariff Escalation on Agriculture-Related Products in WTO Doha Round Negotiations AgEcon
Lee, Huey-Lin; Chang, Ching-Cheng; Weng, Yung-Ho; Hsu, Sheng-Ming; Hsu, Shih-Hsun.
Tariff escalation becomes one of the major issues in the new Doha Round negotiation because it is viewed as a stumbling block to the industrialization development for the developing countries. When tariffs on products escalate with the stage of processing, the effective rate of protection, or the tariff expressed as fractions of value-added after deducting intermediate inputs from product value, also increases. Thus, tariff escalation potentially signals high rates of protection for value-added or processed products, and can inhibit international trade in these goods. The major purpose of this study is to examine the degrees of tariff escalations in Taiwan's agriculture -related commodities and the economic consequences to reduce them. A simplified...

Productivity Change in Taiwan's Farmers' Credit Unions: A Nonparametric Risk-Adjusted Malmquist Approach AgEcon
Chen, Po-Chi; Yu, Ming-Miin; Chang, Ching-Cheng; Hsu, Shih-Hsun.
This article proposes an extended three-stage DEA methodology similar to Fried et al. (2002) to improve the measurement of productivity growth then the assumption of free disposability of undesirable outpu t does not apply. A directional distance function is used to construct adjusted Malmquist-Luenberger productivity indexes which simultaneously account for the impacts of undesirable outputs, environmental variables, and statistical noise. Panel data for 264 farmers' credit unions (FCUs) in Taiwan covering the 1998-2000 period are employed to illustrate the advantages of this method. On average, the productivity of Taiwan's FCUs is found to have deteriorated over the 1998-2000 period. Although an improvement in efficiency has been observed, the major...

AN ANALYSIS ON POTENTIAL ECONOMIC IMPACTS OF GREENHOUSE GAS MITIGATION THROUGH PLANTING ENERGY CROPS IN TAIWAN AgEcon
Chen, Chi-Chung; Hsu, Shih-Hsun.
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.

An Economy-wide Analysis of Impacts of WTO Tiered Formula for Tariff Reduction on Taiwan AgEcon
Hsu, Shih-Hsun; Chang, C.; Li, S.; Chen, Y..
In this study we use Taiwan as a case study to provide an economy-wide analysis of impacts on Taiwan of WTO tariff reduction schemes with different combinations of thresholds and reduction rates. The model we utilized in this study is Taiwan General Equilibrium Model with a WTO module (TAIGEM-WTO, hereafter) that is a multi-sectoral computable general equilibrium (CGE) model of the Taiwan's economy derived from Australian ORANI model (Dixon, Parmenter, Sutton and Vincent, 1982). Simulation results show that results are more sensitive to the scheme of tariff-reduction (i.e., Category 1, 2, and 3) than the tiered levels (i.e., A, B, C, and D) and as a strategy we should pay more attention to the arguments related to the amounts of tariff-reduction. Moreover,...

SPATIAL EQUILIBRIUM MODELING WITH IMPERFECTLY COMPETITIVE MARKETS: AN APPLICATION TO RICE TRADE AgEcon
Chen, Chi-Chung; McCarl, Bruce A.; Chang, Ching-Cheng; Hsu, Shih-Hsun.
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...

Food Security - Global Trends and Region Perspective with Reference to East Asia AgEcon
Chang, Ching-Cheng; Hsu, Shih-Hsun.
The sharp increase in global food prices during 2007‐2008 has triggered the awareness of food insecurity problems and their impacts on the low income, food‐deficit countries many of which are located in the East Asian countries. The food‐security situation was good in relative terms given that the percentage of carbohydrates consumed is slightly lower than the world average while proteins and fats consumption are higher than that of other regions. The food security in East Asia is largely driven by domestic production performance, and despite the doubling of import volume during the last decade, Asia remains the least dependent of all regions on food imports. Nevertheless, the rising energy costs and grain prices induced by the increasing demand of grains...

An Economy-wide Analysis of Increasing Bio-Ethanol Production in Taiwan AgEcon
Lee, Duu-Hwa; Lin, Hsin-Chun; Chang, Ching-Cheng; Hsu, Shih-Hsun.
This article figures out the economic impacts on macroeconomy, industrial output, new energies and environment when the advantageous bioethanol and its feedstock production increase and replace the usage of gasoline in the future. A CGE model, called ¡§Taiwan General Equilibrium Model-Energy, (TAIGEM-E), was a linear/dynamic, linearized percentage change simulation tool used especially in the economic evaluation of environment policies. Results indicated that macroeconomic and environmental variables will all benefit with scenarios. Government should instantly encourage the production of bioethanol (and biodiesel) and it¡¦s producing resource because it truly can reduce the pressure of CO2 emission mitigation, and also can active agricultural fallow lands....

An Ex post Evaluation of Economic Impacts of Foot-and-Mouth Disease on Taiwan Using a Dynamic Computable General Equilibrium Model AgEcon
Hsu, Shih-Hsun; Lee, Duu-Hwa; Chang, Ching-Cheng; Lin, Hsing-Chun; Yang, Tzu-Chiang.
The outbreak of foot-and-mouth disease (FMD) in 1997 has resulted in significant losses to Taiwan's hog industry which was the most important industry in Taiwan's agricultural sector at that time. Hog farmers have suffered great losses due to the cost of slaughtering infected hogs and reduced revenues in the hog market. Furthermore, all pork exports are prohibited according to the Office International des Epizooties (OIE) regulation. There have been a number of ex ante studies that have quantified the potential impacts of FMD on Taiwan's economy (e.g., Tsai 1999, Lin and Hsu 1999). That is, the potential impact assessment was done when the event of FMD just broke out. This article provides an ex post economy-wide assessment of the FMD impacts on...

AN ECONOMY-WIDE ANALYSIS OF GM FOOD LABELING POLICIES IN TAIWAN AgEcon
Chang, Ching-Cheng; Hsu, Shih-Hsun; Wu, Chia-Hsuan.
The development of agricultural biotechnology offers the opportunity to increase crop production, lowers farming costs, improves food quality and could reduce costs to consumers. For the food importing economies, the import quantities as well as prices will be affected through world market as the production technology of GM crops is adopted by the exporting countries. Many sectors will be affected by the use of these crops through vertical (or backward) and horizontal (or forward) linkages. The purpose of this paper is to develop an economy-wide quantitative assessment of the economic impacts of the introduction of GM products with and without labeling. The modeling framework used in this analysis is TAIGEM (Taiwan General Equilibrium Model), a...

Efficiency Measurements in Multi-activity Data Envelopment Analysis with Shared Inputs: An Application to Farmers’ Organizations in Taiwan AgEcon
Chen, Po-Chi; Hsu, Shih-Hsun; Chang, Ching-Cheng; Ming-Miin, Yu.
A multi-activity DEA model with variable returns to scale is proposed to provide information on the efficiency performance of organizations with inputs shared among several closely-related activities. The model is applied to study the case of 279 farmers’ cooperatives in Taiwan. The results provide overall and individual performance measures for each activity as well as suggestions for future improvement. Inter-firm networking should be strengthened and thus policies that promote the consolidation of TFCs will not be sufficient to meet the public goal of institutional reform.
