This paper assesses the role of the public sector in adaptation to climate change. We first offer a definition and categorisation of climate change adaptation. We then consider the primary economic principles that can guide the assignment of adaptation tasks to either the private or the public...

We develop a model of firm learning in volatile markets with noisy signals and test its predictions using historical German data. Firms' forecasts improve with age. We exploit German Reunification as a natural experiment where firms in the East are treated with ignorance about the distribution...

Adaptation to climate change is gaining increasing relevance in the public debate of climate policy. However, detailed and regionalised cost estimates as a basis for cost-benefit-analyses are rare. We compose available cost estimates for adaptation in Europe, and in particular Germany, Finland...

This paper uses an oligopoly model with heterogeneous firms to examine how an industry adjusts to rising import competition. The model predicts that in the short run the least efficient firms in the industry become inactive, surviving firms face a fall in output, mark-ups and profits, and the...

There is a lively debate on the persistence of the current banking crisis' impact on GDP. Impulse Response Functions (IRF) estimated by Cerra and Saxena (2008) suggest that the effects of earlier crises were long-lasting. We show that standard estimates of IRFs are highly sensitive to...

Sovereign defaults are bad news for investors and debtor countries, in particular if a default becomes messy and protracted. Why are some debt crises resolved quickly, in a matter of months, while others take many years to settle? This paper studies the duration of sovereign debt crises based on...

How costly are sovereign debt crises? In this paper we study output losses during sovereign default and debt renegotiation episodes since 1980. In contrast to previous work, we account for the severity of default and not only for its occurrence. Specifically, we distinguish between “hard”...

The objective of this paper is to assess whether external debt makes a difference for public debt stabilization, where external debt is considered through the non-residents' holdings according to a Balance of Payments perspective. The analysis is empirical and considers the case of Italy, one of...

Why do advanced economies fall into prolonged periods of economic stagnation, particularly in the aftermath of credit booms? We present a model of persistent aggregate demand shortage based on strong liquidity preferences of households, in which we incorporate financial imperfections to study...

As is now well documented, aid is given for both political as well as economic reasons. The conventional wisdom is that politically-motivated aid is less effective in promoting developmental objectives. We examine the ex-post performance ratings of World Bank projects and generally find that...
