Two migration scenarios are assessed. In the first, total labour supply is affected. In the second, the importance of migratory flows by differential labour skill types is investigated. The results indicate significant differences in the extent to which regional economies are affected by immigration. They also suggest that remote regions are highly vulnerable to the out-migration of skilled workers ('brain-drain') while the in-migration of unskilled workers leads to widening wage inequality.

In this context, regional economies undergo significant changes affecting both producing and consuming sectors of the economy. This work demonstrates the application of an ...

Rurality defines a territorially specific entrepreneurial milieu with distinct physical, social and economic characteristics. Location, natural resources and the landscape, social capital, rural governance, business and social networks, as well as information and communication technologies, exert dynamic and complex influences on entrepreneurial activity in rural areas. Rurality is viewed as a dynamic entrepreneurial resource that shapes both opportunities and constraints. Rural entrepreneurship is depicted as a three-stage sequential process highly influenced by specific territorial characteristics. The proposed research agenda addresses issues related to theoretical studies concerning entrepreneurial processes in rural areas and more applied issues concerning the formulation of integrated and competent policies supporting entrepreneurship in such areas.

This, as demonstrated by OECD work, is a sina qua non. The agricultural sector has been a highly innovative sector. In many countries, the "Green Revolution" has been the result of scientific developments in agriculture that have brought about a rapid increase in productivity growth, the development of new crop varieties, and increased yields. Major challenges remain, however, as do opportunities in further greening economic activity. Farm management practices that increase productivity, stability and resilience of production systems need to be encouraged and the technology for sustainable development must go well beyond just raising yields. It must also save water and energy, reduce risks, improve product quality and protect the environment. Technologies and farm practices that can contribute to an economically efficient farm sector and provide financial viability for farmers, while at the same time improve environmental performance in a way that is acceptable to society will provide "triple dividends" to green growth. Based on a literature review, this report analyses the effects on resource productivity and efficiency of key farm management practices with green growth potential as compared to conventional agriculture. The selected practices examined include: soil and water conservation practices; integrated pest management; organic farming; modern agricultural biotechnology; and precision agriculture. This report was prepared by the OECD Trade and Agriculture Directorate. It was declassified by the OECD Joint Working Party on Agriculture and the Environment (JWPAE) in December 2015 under the title The Impact of Various Farm Management Practices on Resource Efficiency and Productivity.

Crosscompliance measures applied under the Common Agricultural Policy (CAP) form the backbone of the soil conservation policy in Greece. CAP reforms and especially the transition to decoupled farm payments, instability in world agricultural commodity prices and contradicting agricultural policy signals are the major causes of changing farming practices. The incapability of institutional structures to follow the observed changes is attributed to the lack of appropriate infrastructure and low levels of human capital in quantitative and qualitative terms in the region. Soil conservation efforts are strongly influenced by a piecemeal policy framework and institutional rigidities. The present work uses case studies presenting failures and success in applying soil conservation policy in Greece Institutional capacity, building is necessary to support the implementation of conservation policy at local and regional levels.

Structural changes within a time span of 10 years are estimated using a causative matrix approach, while structural decomposition analysis provides an indication of the attribution of local output growth to changes in the economic structure or final demand. Results reveal that final demand effects on gross production were more important than changes in technical coefficients. Structural policy injections was responsible for around 20.3% of gross production change in Archanes during this period. Also, structural policy specific impacts seem to be quite different, as CAP support measures are associated with comparatively high output and household income benefits for Heraklion and high output and employment benefits for N. Kazantzakis. In contrast, development measures are more successful in generating firm and household incomes in Heraklion and firm income and employment in N. Kazantzakis.

Results reveal that significant transformations took place in this regional economy altering the interdependence between producing and consuming sectors. It is not clear that this change has moved the whole regional economy to a more competitive level as highly supported sectors grew substantially.

A Social Accounting Matrix (SAM) represents production, households, government, etc. in matrix form, while computable GE models introduce greater behavioural flexibility at the cost of parameterisation. Several SAM and CGE models have recently been built for rural regions, while others have tried to represent rural-urban linkages. This paper presents two SAM applications, and one current CGE approach. The first SAM was developed for the analysis of the economic impact of Objective 1 policy on six remote rural areas, including two in Greece. Six specific regional SAMs were used to quantify the growth-generation effects of EU policies and scenarios on these local economies. The second effort used a hybrid three-area SAM for two different rural areas and an adjacent city in Crete to assess the diffusion patterns of economic impacts generated by three types of CAP measure in one of the rural areas. A CGE example, from the ongoing TERA project, seeks to model the determinants of economic agglomeration, and will attempt to cope with rural/urban distance and environmental externalities. Advantages of the SAM approach include its simplicity and availability of data and software. Disadvantages include significant data needs, linear behaviour, no real modelling of growth (development) or price changes, and the fact that some policies apply to many sectors in unknown way. The CGE approach may overcome some of these problems.
