While physical and human capital are established as important predictors of success among early-career clinical investigators, less is known about the role of social capital. The authors aimed to develop a brief scale to assess social capital in this population and test its reliability and validity. A three-item assessment was developed based on a conceptual framework and measures of social cap...

In many agricultural countries, development of rural livelihood through increasing capital is a major regional policy to adapt to climate change. However, the role of livelihood capital in reducing climatic vulnerability is uncertain. This study assesses vulnerability and identifies the effects of common capital indicators on it, using Australian wheat as an example. We calculate exposure (a cl...

A prototypical vintage capital model of economic growth is developed, where the decision to replace old technologies with new ones is modeled explicitly. Technological change is investment specific. Depreciation in this environment is an economic, not a physical, concept. The vintage capital economy's balanced-growth paths and transitional dynamics are analyzed. The transitional dynamics are ma...

This article addresses the lack of empirical study related to depreciation rates, which are a neglected but important ingredient of both micro and macro models and empirical analyses. Based on rich establishment-level survey data, and using a straightforward econometric approach, I estimate depreciation rates ...
