Michael Grossman's human capital model of the demand for health has been argued to be one of the major achievements in theoretical health economics. Attempts to test this model empirically have been sparse, however, and with mixed results. These attempts so far relied on using - mostly...

The paper suggests a consistent interpretation for the much debated Z-footnote on pp. 55-56 of the General Theory and discards claims recently made in the literature concerning the importance of output heterogeneity for Keynes's macroeconomic approach.

Macroeconomic data are indispensable for modern governance, yet it is often unclear how reliable these data are. The production process of macroeconomic data inside the statistical offices is often not very transparent for the general public. Bystanders usually have no choice but to take for...

Nordhaus (2008) has developed a testing strategy for what he calls Baumol's diseases, by which name he designates a number of by-products of structural change that are unwanted from an economic policy perspective. He finds that the U.S. economy is strongly affected by the diseases. This paper...

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...

Towards the end of 2009, the world economy was recovering from its deepest recession since the end of World War II. Most countries around the world took resort to fiscal policy in order to foster this recovery. In this paper, we first discuss the pros and cons of discretionary fiscal policy from...

The paper investigates the nexus between inventory investment and the change in aggregate production for 29 European countries over the period 2000-2009. A special interest is taken in the Great Recession of 2008/09. For most countries, a fairly uniform pattern emerges. Inventory investment is...

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...

Okun's Law postulates a stable relationship between quarterly output growth and changes in (un)employment. This proposition has so far been tested with macroeconomic data at the highest level of aggregation. The paper goes beyond that in extending the analysis to industry data from Switzerland,...

Keynes's essay "Relative Movements of Real Wages and Output" is widely believed to be an important amendment to his General Theory because, in this essay, Keynes relaxed his core assumption of decreasing marginal returns to labour. Non-decreasing marginal returns, however, do not sit comfortably...
