Energy‐saving Technology Choices by Dutch Glasshouse Firms

This paper estimates a sequence of energy‐saving technology choices by Dutch glasshouse firms. The model allows for time‐constant, firm‐specific effects and serial correlation of errors and it is estimated on panel data over the period 1991–1995. The unobserved error sequences are simulated in the model in such a way that they are consistent with the observed choices. The results suggest that positive revenue shocks encourage adoption of new technologies. The choices also exhibit firm‐specific persistency over time. An increase of the price of energy encourages the adoption of a highly efficient energy‐saving technology. The probability of investing in energy‐saving technologies also decreases with capital invested in structures (e.g. double glazing of glasshouses) and increases with capital in energy installations.     

Spatial integration between Finnish and Dutch potato markets

This study estimated a conditional mean model for producer prices of fresh potatoes in Finland and for wholesale selling prices of fresh potatoes in the Netherlands. Unit roots were tested in the Finnish and Dutch price series. Then, an asymmetric error correction model with thresholds was estimated for potato prices between Finland and the Netherlands. Asymmetry was allowed both in short and long-run price transmission. The results suggest that the prices are cointegrated and the arbitrage system is functioning, but with a significant time lag between the Finnish and Dutch potato markets. The price response is also asymmetric in that the Finnish price moves towards a steady state equilibrium faster from above than from below the equilibrium.     

Landowner response to policies regulating land improvements in Finland: Lease or search for other options?

Land improvements with long pay-back periods are often delayed on leased agricultural land. The delay in improvements has been found to result in land degradation, decreased land productivity and environmental problems. An important question is thus how landowners would respond to regulations and mandates concerning land improvements. Based on a Finnish landowner survey, we analysed landowner choices under certain land improvement regulations, using the currently dominant choice of leasing land for agricultural use as the benchmark. The results indicated that land leasing will continue to increase in the future, but if the landowner mandate to co-finance costly land improvements is increased, landowners are predicted to respond significantly to these mandates and search for other land management options. Three heterogeneous landowner groups were identified based on their land use choices. Current leasers and amenity owners, in particular, were sensitive to land improvement mandates, and would avoid compulsory investment expenses by selling or afforesting their land.     

The Struggle to Sustain Agriculture in EU Southern Neighbourhood Partners: Improving Data and Policies

The agricultural sector in the EU Southern Neighbourhood Partners (SNP) is struggling to respond to sustainability challenges. It needs stronger policies to deliver balanced sustainability outcomes in economic, social and environmental terms. Based on recent information and a structured assessment of the impacts of prevailing public policies on the sustainability of agriculture in Tunisia, Morocco, Egypt and Turkey, carried out within the Sustainmed project ( https://sustainmed.iamm.fr ), we conclude that several factors contribute to the struggles in strengthening sustainability functions of agriculture in these countries. In the main, there is a lack of policy coherence toward sustainability uncovered by the dual, unbalanced consideration given to different sustainability factors in the study countries: pure economic factors largely prevail over factors related to resource conservation and social and cultural values, these latter factors being a precondition for long-term economic growth. Consequently, there is a genuine need for a more consistent vision of sustainability issues in future policy agendas, including better data systems and specific policies to incentivise sustainable agriculture in the SNP; as the challenge over the coming decades in these countries will be to increase agricultural production and productivity while at the same time managing natural resources sustainably. Findings can guide policymakers and other stakeholders in the agricultural sector to identify pathways towards sustaining agriculture in the SNP.
