Abstract: Over the past 200 years, the real GDP in western industrialized
countries rose continuously. The decisive factor of long-term economic growth
is technical progress. Beside its macroeconomic importance it is the key
vehicle of competition between research-based pharmaceutical companies. Further
innovative drugs are an integral part of national health care systems in most
industrialized countries. Innovative medicines contribute to the increase in
life expectancy and an improved quality of life. To evaluate the share of
pharmacologic-technical progress in the increase in life expectancy at the
micro- and macroeconomic level it is initially helpful to clarify the economic
relevance of technical progress in general. This will be the purpose of chapter
two. Furthermore, the discussion encompasses the different approaches to define
pharmacological innovations and the associated difficulties to discriminate
between the different types of innovation. The focus of chapter three is the
description of incentive mechanisms, which are fundamental to the Research and
Development (R&D) activities leading to innovative pharmaceuticals.
Beyond that, the micro- and macroeconomic positive effects of pharmaceutical
innovations will be represented and interpreted with the help of existing
results stemming from selected empirical studies. The last chapter gives a
detailed overview on the current empirical results, which illustrate the
versatile interdependencies on macroeconomic level between health and growth.
It demonstrates the channels through which better health can have
growth-enhancing effects.
