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...

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...

A large body of both theoretical and empirical literature has affirmed a positive impact of human capital accumulation in the form of health on economic growth. Yet Baumol (1967) has presented a model in which imbalances in productivity growth between a "progressive" (manufacturing) sector and a...

The share of health care expenditure in GDP rises rapidly in virtually all OECD countries, causing increasing concern among politicians and the general public. Yet, economists have to date failed to reach an agreement on what the main determinants of this development are. This paper revisits...

The paper proposes a new test of endogenous vs. exogenous growth theories based on the Granger-causality methodology and applies it to a panel of 20 OECD countries. The test yields divergent evidence with respect to physical and human capital. For physical capital, the test results favor...

The Review of Political Economy (ROPE) welcomed the year 2009 with an issue in which the first two articles use an interesting yet not very popular modeling framework, namely the aggregate demand/aggregate supply (D/Z) model from Chapter 3 of Keynes’s General Theory. Unfortunately, as I intend...

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...

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...

Since the mid-nineties, U.S. labor productivity outgrows its European counterpart by a wide margin. Several recent studies have found that this result is brought about by relatively few service industries, where productivity growth has accelerated in the U.S., but not so in Europe. Based on this...

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,...
