International audience ; Informationization is the development trend around the world. In terms of agriculture, it is informationization that the Chinese government takes as a significant strategy in order to solve the 'agriculture, farmer and village' problem. Focusing on how to measure the contribution of agricultural informationization to economic growth, this paper explores several key issues in current literatures and summarizes the latest debates in respects of the concept of agricultural informationization, the evaluation method of agricultural informatization, and the calculation method of contribution rate of agricultural informationization to economic growth. This paper finally argues that further research is urgently needed for the contribution rate of agricultural informationization to economic growth due to the existing literature gap regarding the research scope, calculation method, informationization's impact on agriculture itself, and the practice.

In our model, the government operates a mandatory proportional (DC) pension system to substitute for the low life-cycle savings of the lower-paid myopic workers, while maintaining the incentives of the higher-paid far-sighted ones in contributing to the system. The introduction of an appropriate cap on pension contribution (or its base)—excluding the earnings above the cap from the contribution base—raises the optimal contribution rate, helping more the lower-paid myopic workers and reserving enough room for the saving of higher-paid far-sighted ones. The social welfare is almost independent of the cap in a relatively wide interval but the maximal welfare is higher than the capless welfare by 0.3–4.5 %. ; info:eu-repo/semantics/publishedVersion

Simple interventions like changing the default or sending a short message can induce individuals to save more for retirement. However, messages that emphasize high savings rates may increase the amount that savings plan participants save while reducing the total number of plan participants. We study this possibility in the context of a field experiment designed to increase retirement savings by US military service-members. We find that service-members who received a message emphasizing a low contribution rate were more likely to participate in a savings plan than were service-members whose message emphasized a high contribution rate, or no rate at all.
