Most macroeconomic models assume that aggregate output is generated by a specification for the production function with total physical capital as a key input. Implicitly this assumes that private and public capital stocks are perfect substitutes. In this paper we test this assumption by...

Over the last decade, empirical studies analyzing macroeconomic conditions that may affect the size of government spending multipliers have flourished. Yet, in spite of their obvious public policy importance, little is known about public investment multipliers. In particular, the clear...

Recent literature has explored the relationship between efficiency-adjusted public capital and economic growth. A debate on whether capital grants, and especially EU funds actually contribute to growth has gained prominence lately. This paper empirically assesses the relationship between the...

We propose a macroeconomic model to assess optimal public policy decisions in the the face of competing funding demands for climate change action versus traditional welfare-enhancing capital investment. How to properly delineate the costs and benefits of traditional versus adaption-focused...

This paper estimates the impact of public capital on economic growth for forty-eight OECD and non-OECD countries during 1960 - 2001. Using the production function and its extensions, it finds a positive - but concave - elasticity of output with respect to public capital, which is robust to...

This paper investigates the impact of public capital on private sector output by testing and estimating an aggregate production function for the U.S. economy over the postwar period augmented to include the stock of public capital as an additional factor input. We use patent applications to...

The issue of whether government capital is productive has received a great deal of recent attention. Yet empirical analyses of public capital productivity have generally been limited to the official capital stock estimates available in a small sample of countries. Alternatively, many researchers...

Adequate infrastructure has long been viewed as an important factor in economic development. Based on regressions covering 76 advanced and emerging market economies, this paper estimates the impact of infrastructure and investment on income distribution. It finds that better infrastructure, both...
