Channels of Synthesis Forty Years On: Integrated Analysis of Spatial Economic Systems

Hewings, Geoffrey J.D.; Nazara, Suahasil; Dridi, Chokri - EconWPA - 2004

Isard’s vision of integrated modeling that was laid out in the 1960s book Methods of Regional Science provided a road map for the development of more sophisticated analysis of spatial economic systems. Some forty years later, we look back at this vision and trace developments in a sample of...

BIOECONOMICS OF SUSTAINABLE HARVEST OF COMPETING SPECIES: A COMMENT

Neugebauer, Tibor - EconWPA - 2005

Flaaten’s (1991) study on competing species conjectures that a higher price (harvesting costs) of one species yields a lower (greater) own stock-size and a greater (lower) stock-size of the competing species. I show both conjectures are wrong.

Confidence Statements for Efficiency Estimates from Stochastic Frontier Models

Horrace, William C.; Schmidt, Peter - EconWPA - 2002

This paper is an empirical study of the uncertainty associated with estimates from stochastic frontier models. We show how to construct confidence intervals for estimates of technical efficiency levels under different sets of assumptions ranging from the very strong to the relatively weak. We...

Valid Confidence Intervals and Inference in the Presence of Weak Instruments

Nelson, Charles R.; Startz, Richard; Zivot, Eric - EconWPA - 1996

We investigate confidence intervals and inference for the instrumental variables model with weak instruments. Wald-based confidence intervals perform poorly in that the probability they reject the null is far greater than their nominal size. In the worst case, Wald-based confidence intervals...

Inference on a Structural Parameter in Instrumental Variables Regression with Weak Instruments

Wang, Jiahui; Zivot, Eric - EconWPA - 1996

In this paper we consider the problem of making inference on a structural parameter in instrumental variables regression when the instruments are only weakly correlated with the endogenous explanatory variables. Adopting a local-to-zero assumption as in Staiger and Stock (1994) on the...
