The Dynamics of Productivity Changes in Agricultural Sector of Transition Countries AgEcon
Kim, Hanho; Lee, Sangjun; An, Donghwan.
Relying on frontier production approach (e.g., Luenberger's shortage function), we investigated the performance of agricultural sector in transition countries and its changes over time, especially focusing on the dynamics of productivity changes. We found that; (i) CEE countries have improved their performance during the sample period whereas CIS have not; (ii) productivity changes in the last decade was attributable to the technical progress; (iii) overall performance was decelerated for the second 5-year sub-period (1997-2001) in both regions; (iv) agricultural reform has positive effects on the productivity and its components especially in CEE countries.

THE EFFECT OF MARKET STRUCTURE ON ADAPTATION TO CLIMATE CHANGE IN AGRICULTURE AgEcon
Lee, Sangjun; Thornsbury, Suzanne.
When assessing climate change impact, adaptation is an important behavioral response to reduce potential risk. But it has been widely recognized that there are barriers to adaptation. And attempts to estimate impacts may be biased when these barriers neglected. Potential barrier on adaptation decision from market structure have not been identified. We develop a theoretical model to evaluate adaptation incentives of farmers under climate change across various market structures. In agricultural production where acreage adjustment is costly, our theoretical model suggests that the “competition effect” plays an important role in determining incentives to adapt. The competition effect in the market may outweigh the production effect and reduce producer...
