We consider a carbon emissions tax announced today, but implemented after a known time-lag. Before implementation, the announcement induces higher emissions than without intervention. In welfare terms, this adverse announcement effect could more than outweigh the gain after tax implementation....

To limit global warming to 1.5°C, vast amounts of CO2 will have to be removed from the atmosphere via Carbon Dioxide Removal (CDR). Enhancing the CO2 sequestration of ecosystems will require not just one approach but a portfolio of CDR options, including so‐called nature‐based approaches...

Die möglichst präzise und vor allem zutreffende Vorhersage unsicherer zukünftiger Ereignisse ist eine permanente Herausforderung für Unternehmen. Prognosemärkte adressieren diese Aufgabe, indem sie relevante Informationen aufdecken, bewerten und aggregieren. Mit diesem Bericht leisten wir...

Decisions involving risk are usually taken in the presence of other insurable or non-insurable risks, the latter type called background risk. We examine how changing background risk influences risk-taking based on panel data with monthly observations from Senegalese fishermen. Fishing income is...

Innovation clusters combining public and private effort to develop breakthrough technologies promise greater technological advances to slow down climate change. We use a multi-country model with emissions permit trade to examine how international climate policy can incentivize countries to...

This paper explores the long–run development of an economy with a traditional sector based on common–pool resource-use, a modern, resource–independent sector with fixed entry costs, and an imperfect capital market. We show theoretically that introducing resource-use regulations increases...

The paper analyses the effect of interest rate changes on education and child labor in an economy with a high-skilled sector, a low-skilled sector and fragmented credit markets. The high-skilled sector takes educated labor as input. The low-skilled sector takes unskilled labor, physical capital...

Interest payments based on income flows are a common feature of informal loans. Such so-called `interlinked loans' can be seen as an insurance against very low disposable incomes, as interest payments are lowest when income turns out to be low. This paper examines whether interlinked loans...

We introduce an international technology treaty that couples the funding of research for a more advanced abatement technology with an international emissions permit market. Under the treaty, each country decides on the amount of permits for its domestic industries, but a fraction of these...

Innovation clusters that combine public basic research and applied research performed by private firms may be needed for greater technological advances to slow down climate change. We use a multi-country model with emissions permit trade to examine how international climate policy can induce...
