In this study long run relationship between agricultural research and TFP (total factor productivity) is estimated by using Cointegration technique for 1970-2005. The results of the long run relationship between TFP and agricultural research indicate that agricultural research has a significant...

We consider a North-South duopolistic competition in the market of a perishable good. North's harvest can be sold over two periods whereas South's harvest can be sold in the first period only, because of the lack of storage technology. We examine the impact of the availability of a storage...

This paper analyses, within the new growth theory framework and using panel cointegration techniques, the effect of agricultural international technological spillovers on total factor productivity growth for a sample of 47 countries during the period 1970-1992. The analysis shows that total...

In this paper we aim at investigating the price-induced innovation hypothesis in Italian agriculture. We generalize the framework of analysis proposed by Peeters and Surry (2000). The generalization includes a short-run specification of the dual technology as well as a quadratic spline in a time...

The paper presents a dynamic model for the analysis of the National Agricultural Research Systems (NARS) strategy. In a context of increasing globalisation, both intersectoral and international technology spill-ins may greatly affect the NARS design, and this paper proposes an analytical...

This article deals with the role of public research in Italian agriculture during the period 1960 to 1995. A short-term specification of the GL cost function capable of accommodating quasi-fixed factors and variable returns is employed. Temporary equilibrium and scale economies are investigated...

We find three intertwined ambitions that drove federal legislation over wildlife and biodiversity at the beginning of the 20th Century: establishment of multiple-use federal lands, the economic development of natural resources, and the maintenance of option values. We examine this federal...

This paper uses the 1918 influenza pandemic as a natural experiment to examine whether air pollution affects susceptibility to infectious disease. The empirical analysis combines the sharp timing of the pandemic with large cross-city differences in baseline pollution measures based on coal-fired...

Air pollution was severe in many urban areas of the United States in the first half of the twentieth century, in part due to the burning of bituminous coal for heat. We estimate the effects of this bituminous coal consumption on mortality rates in the U.S. during the mid-20th century. Coal...

Disparities in cross-city pandemic severity during the 1918 Influenza Pandemic remain poorly understood. This paper uses newly assembled historical data on annual mortality across 438 U.S. cities to explore the determinants of pandemic mortality. We assess the role of three broad factors: i)...
