Have the Agricultural Public Investments Improved Rice Productivity through Farmland Usage Reallocation?: An Empirical Study on Japanese Paddy-field Rental Transactions

This paper aims to analyze the effects of paddy-field consolidation projects by using the stochastic model. Empirical results showed that the degree of effects, realized as a rise in rental rate and rental-area, vary in each region and that several factors influencing the project effects can be evaluated quantitatively.Land Economics/Use,

Can Asset Management Measures for Agricultural Public Facilities Improve Social Welfare?: Application of the Dynamic Computable General Equilibrium Model

Agricultural public facilities for irrigation and drainage play an important role in Japanese agriculture, especially in paddy production. However, the budget for renovation of old facilities was drastically cut in 2010. For prolonging life time and decreasing lifecycle costs of public facilities, the asset-management measures (AMMs), which reinforce old facilities in stead of reconstruction, have started. This study analyzes effects of the AMMs by the recursive dynamic computable general equilibrium (CGE) model. Simulation results demonstrated that, firstly, the AMMs increased not only agricultural production but also food production via reallocation of production factors and prices. Second, the increase in GDP improved consumption and private investment via an increase in labor income, and decreased the general price of goods and service. Third, consumer price went down and consequently Hicksian Equivalent Variation value, which shows social and economic effects, increased. In this sense, the AMMs bring about positive ripple effects to economies. The dynamic CGE model can also measure such long-term comprehensive effects and is useful for policy analysis.

Direct and Indirect Effects of Public Infrastructure on Regional Economic Growth in Japan: An Application of the Covariance Structure Model by Geographical Classification Area

The direct and indirect effects of public infrastructure (PI) were evaluated by a covariance structure model. Empirical results showed the positive indirect effect, crowding-in effect, as well as the direct effect as an input factor, differences of these effects by the geographical areas and periods.Public Economics,

Macroeconomic Effects of the Stock Management for Irrigation and Drainage Facilities in Japan: Application of Recursive- Dynamic CGE model

The stock management of irrigation and drainage facilities was macro-economically evaluated. The recursive-dynamic CGE model was developed and used for policy simulation. Results demonstrated that effects of activity spread to other industries and total benefit calculated by the consumers’ surplus change was more than the total costs.Computable General Equilibrium Model, Recursive dynamic model, Consumers’ surplus, Cost-benefit ratio, Agricultural and Food Policy, Community/Rural/Urban Development, Demand and Price Analysis, Production Economics, Public Economics, H30, Q12, Q14, Q18,

Trade-off between Economic Revitalization and Social Capital: Application of Structural Equation Model in Japan

An income inequality has been expanded in Japan and some policy is highly needed to revitalize rural areas. This study aims to show causative factors on regional satisfaction level by the estimation of the structural equation model (SEM) with data of each town in Yamagata and Yamaguchi prefectures. Results demonstrate that (i) both the economic situations and social capital (represented by trust, altruistic moral and human network) positively affected the satisfaction level, but there is a trade-off between these effects, (ii) public facilities can increase satisfaction level as long as these facilities are built with consideration of residents' needs and quality, and (iii) the economic factor and social capital have indirect effects, affecting to satisfaction via other factors, and there are some trade-off effects within the indirect paths. Hence, regional economic gaps can be alleviated by the social capital that is highly maintained in less favored areas. The same tendency as above is shown in both prefectures, so it can be said that these factors are possibly general in Japan.Direct and indirect effects, Evaluation for public facilities, Regional economic situations, Social capital, Trade-off effect, Community/Rural/Urban Development, O15, R11, R15, R53, R58,

Macro Economic Impacts of Installing Rice Husk Electricity Power Plants in Thailand

Macro economic impacts of rice-husk power plants (RHPP) in Thailand were analyzed by an Input/Output method. Results show that RHPP decreased sensitivity coefficients especially in the petroleum-sector, economic merits were realized in the agricultural-sector but total induced production effects were lowered, and induced imports by consumption were reduced with RHPP.I/O analysis, Sensitivity coefficient, Oil price, Biomass resource use, Crop Production/Industries, C67, O13, Q20, Q42, Q43,

Causative factors for changes in total factor productivity of Japanese agriculture under the era of climatic uncertainty

This study analyzed causative factors on TFP growth in Japanese agriculture. The regression analysis with consideration of correlation between factors demonstrated that without further deregulation for introducing new comers, enlarging farm management area and asset management for keeping public capital, agricultural TFP cannot be improved in the future.fertility of farmland, human factor, scale economies, public capital stock, knowledge capital stock, technological progress, Total Factor Productivity, Agricultural and Food Policy, Production Economics, Productivity Analysis, Public Economics,
