In the long term, productivity and especially productivity growth are necessary conditions for the survival of a farm. This paper focuses on the technology choice of a dairy farm, i.e. the choice between a conventional and an automatic milking system. Its aim is to reveal the extent to which economic rationality explains investing in new technology. The adoption of robotics is further linked to farm productivity to show how capital-intensive technology has affected the overall productivity of milk production. The empirical analysis applies a probit model and an extended Cobb-Douglas-type production function to a Finnish farm-level dataset for the years 2000–10. The results show that very few economic factors on a dairy farm or in its economic environment can be identified to affect the switch to automatic milking. Existing machinery capital and investment allowances are among the significant factors. The results also indicate that the probability of investing in robotics responds elastically to a change in investment aids: an increase of 1% in aid would generate an increase of 2% in the probability of investing. Despite the presence of non-economic incentives, the switch to robotic milking is proven to promote productivity development on dairy farms. No productivity growth is observed on farms that keep conventional milking systems, whereas farms with robotic milking have a growth rate of 8.1% per year. The mean rate for farms that switch to robotic milking is 7.0% per year. The results show great progress in productivity growth, with the average of the sector at around 2% per year during the past two decades. In conclusion, investments in new technology as well as investment aids to boost investments are needed in low-productivity areas where investments in new technology still have great potential to increase productivity, and thus profitability and competitiveness, in the long run.

The literature on unemployment has mostly focused on labor market issues while the impact of capital foonation is largely neglected Job-creation is often thought to be a matter of encouraging more employment on a given capital stock. In contrast, this paper explicitly deals with the long-run consequences of institutional shocks on capital foonation and employment. It is shown that the usual trade off between employment and wages disappears in the long run. In line with an appropriation model, the estimated values for the long-run elasticities of substitution between capital and labor for Germany and France are substantially greater than one.

Negotiations between the US and the European Union (EU) on a joint free-trade agreement began in July 2013. The economies involved are hoping for more intense trade activities, stronger economic growth and higher employment rates. A current study of the ifo Institut commissioned by the Bertelsmann Stiftung shows that these expectations would be met. For most other countries in the world, however, this would result in welfare loss. In the following we sketch some of the possible economic consequences of a comprehensive transatlantic free-trade agreement for the Asian region.

Although they are not the deciding factor, the Western financial sanctions are nevertheless an important factor affecting the deteriorating economic situation in Russia. They have significantly undermined the opportunities which Russian companies have to attract foreign capital, thus contributing to the deterioration of their financial condition (which is particularly prominent in the case of energy firms subject to sanctions). Therefore, Russian businesses need more support from the state. However, this support is becoming more difficult due to the dramatic fall in oil prices – revenues from oil exports are the main source of budget revenue.

Since mid-2015 Turkey has been affected by a deep internal crisis, caused by rising political polarisation, increased levels of terrorist threat (posed by the Kurds and Islamic radicals) and the revived conflict with the Kurdistan Workers’ Party (PKK). As a consequence of this crisis, over 350,000 residents of south-eastern Turkey have been forced to leave their homes. At the same time, due to the migration crisis and despite mutual distrust in relations between Turkey and the EU, cooperation between Ankara and Brussels has been intensifying. Turkey’s ongoing destabilisation does not challenge the status of the ruling Justice and Development Party (AKP), which is de facto controlled by President Recep Tayyip Erdoğan; paradoxically, it strengthens the party. The internal crisis which the authorities have been deliberately fuelling is an element of a plan to rubber-stamp political change by introducing a presidential system of government. This is happening amid a thorough reconstruction of the socio-political order which has been underway for over a decade. In the upcoming months it is expected to result in the constitution being changed and, as a consequence, the institutionalisation of Erdoğan’s autocratic rule.

Most of the policy debate surrounding the actions needed to mitigate and adapt to anthropogenic climate change has been framed by observations of the past 150 years as well as climate and sea-level projections for the twenty-first century. The focus on this 250-year window, however, obscures some of the most profound problems associated with climate change. Here, we argue that the twentieth and twenty-first centuries, a period during which the overwhelming majority of human-caused carbon emissions are likely to occur, need to be placed into a long-term context that includes the past 20 millennia, when the last Ice Age ended and human civilization developed, and the next ten millennia, over which time the projected impacts of anthropogenic climate change will grow and persist. This long-term perspective illustrates that policy decisions made in the next few years to decades will have profound impacts on global climate, ecosystems and human societies — not just for this century, but for the next ten millennia and beyond.

Background/Aims: The simultaneous use of alcohol and cannabis is common among adolescents, but has been little studied. In this study, we examine predictors and consequences of this behavior in a population-based sample of high school students. Method: Self-reports were obtained from students in Quebec (Canada) followed throughout high school (N=6589). Logistic regressions were used to test the association between individual, family, and peerrelated predictors in grades 7–8 and simultaneous alcohol and cannabis use in grade 10, as well as between simultaneous alcohol and cannabis use in grade 10 and experiencing 3 or more substance-related problems of various types (legal, physical, etc.) in grade 11. Results: Most predictors in grades 7–8 were associated with simultaneous alcohol and cannabis use in grade 10. Only variables reflecting early-onset substance use involvement — alcohol intoxication, cannabis use, and drug use by close friend(s) — remained predictive in a multivariate model. Simultaneous alcohol and cannabis use was associated with increased substance-related problems in grade 11, above and beyond baseline problems and the concurrent use of the two substances in separate episodes in grade 10. Conclusions: Simultaneous alcohol and cannabis use 1) is anticipated by multiple psychosocial risk factors which come together with individual and peer substance use in early high school and 2) is independently predictive of subsequent substance-related problems. Providing adolescents with adequate information regarding the potential harm of simultaneous use may be a useful prevention strategy.
