there are many indices for measuring property rights (pr) security. they may be classified into two groups: subjective proxies and objective proxies. most of the proxies are subjective. one contribution of this paper is introducing a new approach for measuring government expenditures devoted to pr protection. calculating physical capital within the introduced new approach is another contributio...

The relationship between physical capital, human capital and the distribution of earnings is examined empirically using cross-sectional microdata within SMSAs. Comparative advantage in workers and a scale-of-resources effect among firms is predicted to lead to a relationship between capital and earnings. The level of earnings is found to be positively related to capital intensity and negatively...

In recent years substantial progress has been achieved in the field of ecological economics for clarifying human-nature interrelations. The fundamental role of the lifesupport functions of the environment (Odum, 1975) for economic development and sustainability has entered from ecology into economics, and has started to be theoretically as well as empirically analyzed. This has, in part, given ...

Two of the first volumes this year of the Proceedings B of the Royal Society have been dedicated to the issue of sustainable agriculture, signalling researchers’ concerns about the urgent need to address this issue. The editors, Chris Pollock, Jules Pretty, Ian Crute, Chris Leaver and Howard Dalton, highlight issues that continue to fail to impact more widely. And they are blunt in their assess...

human capital has always been of high importance in economic growth literature. in this regard, several studies have tried to explain the role of this variable via the use of different models. the present study, in line with the previous ones, going to estimate the share of human capital in iranian economy production from 1974 to 2011 within the framework of ozawa (1965) and lucas’s (1988) endo...

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...

the authors examine the effects of government expenditure on economic growth in iran, using annual data for the period of 1973-2003. in this paper, they lookat the offects of human, physical capital, and government budget on gdp. in the model developed in this paper, accumulation of human capital is dependent on physical. human capital, and government budget as well. the result indicate that go...

Intangible capital has arguably become an important component of corporate value. However, it is still an open question whether uncertainty associated with investment in intangible capital is higher or lower than physical capital. We estimate the value of intangible capital in a dynamic stochastic general equilibrium model that features capital adjustment costs, investment-speci c technological...
