For many years now, nitrate concentrations have exceeded the trigger value of 50 milligrams per liter at nearly one-fifth of the groundwater sampling sites in Germany. Apart from impairing the ecosystem by, for example, causing eutrophication of water bodies, nitrate-polluted drinking water also damages human health; it is suspected to cause cancer. Econometric calculations using current data confirm ...
Belastung in Regionen mit vorwiegend agrarwirtschaftlicher Nutzung höher als in anderen Gebieten – Grundpreise für Trinkwasser höher in Regionen mit Grenzwertüberschreitung – Genauere Erhebung, zentrale Erfassung und stringente Kontrolle des Düngemitteleinsatzes erforderlich Deutschlands Grundwasser weist europaweit eine der höchsten Belastungen mit Nitrat ...
Seit vielen Jahren übersteigt die Nitratbelastung an knapp einem Fünftel der Grundwasser-Messstellen in Deutschland den Grenzwert von 50 Milligramm pro Liter. Neben der Beeinträchtigung des Ökosystems, zum Beispiel durch Eutrophierung von Gewässern, schädigt nitratbelastetes Trinkwasser auch die menschliche Gesundheit und es besteht der Verdacht einer krebserregenden Wirkung. Ökonometrische Berechnungen ...
This paper studies the impact of financial investments on agricultural futures prices, using structural vector autoregressions. We identify exogenous variation in net long positions of speculators through heteroskedasticity. We first show that demand shocks of both index investors and noncommercial traders lead to a statistically significant contemporaneous increase in futures prices. We then quantify ...
The European Green Deal includes the goal of enshrining the long-term objective of climate neutrality by 2050 in legislation and increasing the EU’s climate by 2030. In this context, the Green Deal emphasized that “should differences in levels of ambition worldwide persist, as the EU increases its climate ambition, the Commission will propose a carbon border adjustment mechanism, for...
Fair Trade certification aims at transferring wealth from the consumer to the farmer; however, coffee passes through many hands before reaching final consumers. Bringing together retail, wholesale, and stock market data, this study estimates how much more consumers are paying for Fair Trade-certified coffee in US supermarkets and finds estimates around $1.50 per lb. The study then assesses how this ...
We examine the impact of a disclosure mandate for greenhouse gas emissions on firms’ subsequent emission levels and financial operating performance. For UK-incorporated listed firms a carbon disclosure mandate was adopted in 2013. Our difference-in-differences design shows that firms affected by the mandate reduced their emissions by about 8% relative to a control group of European firms. At the same ...
