This paper serves to disentangle the complex system of Indian food policies related to wheat and rice procurement, storage, distribution and trade. Using nationally aggregated time series data, these policies are econometrically analysed. Based on the estimation results, their market...

The role of futures markets in stabilizing spot prices has been extensively discussed. Nevertheless, the ability of these markets to achieve the stabilizing function significantly depends on whether they are ‘efficient’ in the sense that futures prices ‘fully reflect’ the available...

Understanding how producers make decisions to allot acreage among crops and how decisions about land use are affected by changes in prices and their volatility is fundamental for predicting the supply of staple crops and, hence, assessing the global food supply situation. The innovations of the...

Im Kern eines Instrumentenmixes für die deutsche Energie- und Klimapolitik sollte nach Ansicht von Andreas Löschel, Universität Münster, eine allgemeine CO2-Bepreisung stehen, die einen ökonomisch sinnvollen und langfristigen Rahmen für die umfangreiche Transformation setzt. Bei...

This paper analyzes the transmission from global commodity to domestic food prices for a large set of countries. First, a theoretical model is developed to explain price transmission for different trade regimes. Drawing from the competitive storage model under rational expectations, it is shown...

This paper evaluates the consequences of renewable energy policies on welfare and energy prices in a world where carbon pricing is imperfect and the regulator seeks to limit emissions to a (cumulative) target. The imperfectness of the carbon price is motivated by political concerns regarding...

This paper takes the ‘policy failure’ in establishing a global carbon price for efficient emissions reduction as a starting point and analyzes to what extent technology policies can be a reasonable second-best approach. From a supply-side perspective, carbon capture and storage (CCS)...

The "green paradox" by Hans-Werner Sinn suggests that increasing resource taxes accelerate global warming because resource owners increase near-term extraction in fear of higher future taxation. In this note we show that this effect does only occur for the specific set of carbon taxes that...

We investigate conditions that aggravate market failures in energy innovations, and suggest optimal policy instruments to address them. Using an intertemporal general equilibrium model we show that “small” market imperfections may trigger a several decades lasting dominance of an incumbent...

We investigate conditions that amplify market failures in energy innovations, and suggest optimal policy instruments to address them. Using an intertemporal general equilibrium model we show that ‘small’ market imperfections may trigger a several decades lasting dominance of an incumbent...
