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 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...

Hartwig (2008) has presented empirical evidence that the difference between real wage growth and productivity growth at the macroeconomic level is a robust explanatory variable for deflated health-care expenditure growth in OECD countries. In this paper, we test whether this finding is robust to...

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...

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...

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...

In this paper we extend the targeted-regressor approach suggested in Bai and Ng (2008) for variables sampled at the same frequency to mixed-frequency data. Our MIDASSO approach is a combination of the unrestricted MIxed-frequency DAta-Sampling approach (U-MIDAS) (see Foroni et al., 2015; Castle et...

Google Trends have become a popular data source for social science research. We show that for small countries or sub-national regions like U.S. states, underlying sampling noise in Google Trends can be substantial. The data may therefore be unreliable for time series analysis and is furthermore...

This article re-examines the findings of Stock and Watson (2012b) who assessed the predictive performance of dynamic factor models (DFM) over autoregressive (AR) bench-marks for hundreds of target variables by focusing on possible business cycle performance asymmetries in the spirit of Chauvet...
