NGOs play an important role in international development cooperation, but the allocation of NGO aid has rarely been mapped, let alone explained. Based on a representative dataset for 61 important NGOs from various OECD countries, we analyze the targeting of NGO aid across a large number of...

I measure the rate of aversion to inequality in consumption as expressed in the development aid given by rich countries to poor ones between 1965 and 2005. Over time, OECD countries have become less concerned about international inequity. Even for a fairly leaky bucket, the consumption rate of...

The Stern Review reported a social cost of carbon of over $300/tC, calling for ambitious climate policy. We here conduct a systematic sensitivity analysis of this result on two crucial parameters: the rate of pure time preference, and the rate of risk aversion. We show that the social cost of...

This paper discusses the issue whether developing countries forego chances in world manufactured markets by protecting intermediate services against market entry of new suppliers. By scanning the empirical literature on effective rates of protection (ERP), the evidence is supportive. Yet, it...

From a theoretical perspective, the output gap is probably the most comprehensive and convincing concept to describe the cyclical position of an economy. Unfortunately, for practical purposes, the concept depends on the determination of potential output, which is an inherently unobservable...

Against the backdrop of Baumol's model of unbalanced growth, a recent strand of literature has presented models that manage to reconcile structural change with Kaldor's stylized fact of the relative constancy of per-capita GDP growth. Another strand of literature goes beyond this, arguing that...

In a recent paper I argued that Baumol's (1967) model of unbalanced growth offers a ready explanation for the observed secular rise in health care expenditure (HCE) in rich countries (HARTWIG 2006). Baumol's model implies that HCE is driven by wage increases in excess of productivity growth. I...

This paper identifies tax policy that both speeds recovery from the current economic crisis and contributes to long-run growth. This is a challenge because short-term recovery requires increases in demand while long-term growth requires increases in supply. As short-term tax concessions can be...

We show that a flex-price two-sector open economy DSGE model can explain the poor degree of international risk sharing and exchange rate disconnect. We use a suite of model evaluation measures and examine the role of (i) traded and non-traded sectors; (ii) financial market incompleteness; (iii)...

The governance and organisation of scientific research undertaken for publication have altered significantly since the end of the Second World War in many industrialised economies. These changes have had significant effects on authority relations governing research goals, approaches and the...
