We use newly constructed state-specific data to explore the implications of common modeling choices for measures of research returns. Our results indicate that state-to-state spillover effects are important, that the research and development lag is longer than many studies have allowed, and that misspecifi­ cation can give rise to significant biases.

During early embryogenesis in Drosophila melanogaster, extensive vesicle transport occurs to build cell boundaries for 6,000 nuclei. Here we show that this important process depends on a functional complex formed between the tumour suppressor and adaptor protein Discs-Large (Dlg) and the integral membrane protein Strabismus (Stbm)/Van Gogh (Vang).

Commodity levies are used increasingly to fund producer collective goods such as research and promotion. In the present paper we examine theoretical relationships between producer and national benefits from levy-funded research, and consider the implications for the appropriate rates of matching government grants, applied with a view to achieving a closer(More)

Agricultural research has transformed agriculture and in doing so contributed to the transformation of economies. Economic issues arise because agricultural research is subject to various market fail­ ures, because the resulting innovations and technological changes have important economic consequences for net income and its distri­ bution, and because the(More)
The structure of U.S. agricultural production changed dramatically during the 20 th Century. Major technological innovations transformed the relationship between agricultural inputs and outputs, and contributed to rapid increases in agricultural productivity. However, evidence is mounting that suggests we have entered a new era, with substantially lower(More)
