AboutAbout the lab
Solving everyday food and agriculture problems with economics
Saito Lab conducts research that uses economics to solve everyday problems related to food and agriculture.
The world's economies are becoming more closely connected, and to understand any single economic phenomenon, one also has to look at the ties between countries and regions behind it.
Building on general equilibrium theory, the lab aims to clarify the wide range of economic phenomena related to food and agriculture, and how they change, through both theory and data.
Research topics are open as long as they address food and agriculture from an economic perspective, whether micro or macro, Japan or overseas, developing or developed countries.
Key terms
- General equilibrium theory
- An economic theory that considers how all markets in an economy influence one another and reach a balanced state as a whole
- Input-output analysis
- An analysis that tabulates the flows of goods and services between industries and examines how a change spreads through the whole economy
- Food security
- The idea that everyone should be able to obtain the food they need, reliably and at all times
ResearchResearch themes
Building on general equilibrium theory, the lab studies economic phenomena related to food and agriculture through both theory and data. Its research is grounded in econometric methods, input-output analysis, and computable general equilibrium (CGE) analysis.
*Illustrative imageEconomic development and food security
The lab quantitatively analyzes, from both micro and macro perspectives, the role of agriculture in economic development, relations between countries at different stages of development (agricultural and trade policy), food security in developing countries, and the effects of climate change on agriculture.
*Illustrative imageAnalyzing the whole economy as a single system
Placing emphasis on interdependence with other sectors, the lab treats the whole economy as a single system and analyzes it numerically. It also carries out interdisciplinary research, such as evaluating the impact of livestock epidemics on agricultural trade from a food security perspective.
