International Risk Sharing and Government Moral Hazard

This paper analyzes incentive problems caused by international risk sharing. They arise because international risk sharing contributes to the insurance of domestic consumption and thus lowers governments’ incentives to increase output. We show that the resulting distortions can lead to substantial efficiency losses. Complete risk sharing is, therefore, undesirable and the optimal degree of risk sharing may be low. Furthermore, we show that households’ risk sharing decisions are socially inefficient and are effectively maximizing government moral hazard. As a result, financial innovation and integration may reduce welfare by increasing households’ risk sharing opportunities.

Old wine in new bottles

Trade restrictions are being justified by arguments for harmonisation of minimum labour or environmental standards. But diverse standards are one of the sources of the gains from trade. Protectionism can be concealed '…under a cloak of concern for workers in developing countries or for the global environment.'

The future of cooperation between the EU and ACP countries

Something over 20 years after the first Lomé Agreement came into force, most of the ACP countries are still among the poorest in the world. Why have these countries' situations not improved despite the Agreements? Why has their share of total EC imports from developing countries fallen in spite of the tariff preferences they are granted? What conclusions ought to be drawn for future cooperation between the EC and ACP countries?     

Can Futures and Options Markets Hold the Milk Price Safety Net? Policy Conflicts and Market Failures in Dairy Hedging

U.S. Department of Agriculture's Dairy Options Pilot Program promoted hedging by producers, and was a test case for similar programs in other agricultural industries. Rapidly shifting milk pricing policies impeded quantitative hedging evaluations while the program was active. Hedging appears capable of reducing price variance by 50–60% in most regions, and favors large, sophisticated producers in heavy cheese manufacturing regions. Forward contracting or price insurance products may offer lower transaction costs and attract more small-scale producers. Ballooning milk deficiency payments and milk's prominent role in trade-distorting payments suggest an ongoing need to promote private price risk management tools.     

Consumption of Economic Information in Agriculture

We develop a model of decision makers' demand for agricultural economic information services. This model treats choice of external decision-support services as a function of actors' assessment of how alternative investments in information complement their internal competencies. Data from a survey in four commodity systems are used to evaluate hypotheses as to how human capital, and functional role of actors in commodity systems affect demand for variously formatted information. By focusing on three axes of heterogeneity—diversity among decision makers, information service providers, and information—we are able to identify key structural and functional relationships in agricultural economic information systems.     

We Still have That Sinking Feeling

It is nearly five years since financial turmoil broke upon an unsuspecting world, in August 2007. So how are crisis-stricken high income countries doing? Badly, is the only answer. Of the six largest high income economies (plus the eurozone), only those of the US and Germany are above previous peaks. Since the US was the epicentre of the early shocks, its recovery has been relatively good. Yet none of these countries can be happy with its performance. While US gross domestic product has     

Modellgestützte Bewertung des Kraft-Wärme-Kopplungsgesetzes 2016 anhand ausgewählter Anwendungsfälle in Wohngebäuden

Cogeneration is a promising technology in the energy transition amongst other things in view of its energy efficiency and its broad applicability in the household, tertiary and industry sectors. For the promotion of cogeneration technologies, support schemes are in place in German energy policy. Amongst other things the Combined Heat and Power (CHP) Act serves as the main instrument for the promotion since 2002. In the new version of the CHP Act of 2016 the German Federal Government strives towards a more market-oriented design resulting in significant amendments featuring inter alia a highly case-dependent tariff design with modified levels and durations of remuneration. It is therefore the aim of the present study to assess these modifications with respect to technical, economic and ecological aspects in a model-based approach by means of selected use cases at different levels of spatial aggregation for residential buildings. Results point to an economic advantageousness for cases of the medium energy consumption level (streets and blocks of houses) under the new regime as well as the reversal of this attractiveness for objects of high consumption (neighbourhoods, districts). Particularly, CHP plants tend be dimensioned comparatively smaller with a greater number of full-load hours under the new regime. Furthermore, implications with regard to technical and ecological aspects are shown in this contribution.
