The 2015-17 Tjalling C. Koopmans Econometric Theory Prize has been awarded to Javier Hidalgo (London School of Economics) and Myung Hwan Seo (Seoul National University) for their paper “Specification Tests for Lattice Processes,” by Econometric Theory. The paper was published in the April 2015 issue of Econometric Theory (volume 31(2), pages 294–336).

The prize was announced in the latest issue of Econometric Theory, where journal editor and Cowles research staff member, Peter C.B. Phillips, along with Cambridge University Press, congratulated the authors on their success in receiving the award.

The selection of the winning article was made by the Advisory Board of the Journal. All articles published in Econometric Theory over 2015–2017 inclusive were candidates for the prize, except those that were authored or coauthored by the Editor and members of the Advisory Board. The citation of the winning paper (written by the Advisory Board and Editor) is as follows:

The article explores the properties of weakly stationary (scalar) random sequences x(t) in which the parameter (t) may be d dimensional on a lattice. Important examples are, for d = 1, noncausal linear dynamical systems and, for d > 1, spatial and spatiotemporal systems, which play a major role in many scientific areas. Many relevant examples of such processes arise in environmental and development economics. Within this wide context, x(t) is assumed to be a generalized “spatial” linear process, with unobserved “spatial” i.i.d. inputs. This formulation leads to a transfer function in d variables and a spectral density in d variables. The article contributes by developing statistical tests for correct specification of the dynamics of x(t), or more precisely, tests of the hypothesis that the covariogram of x(t) follows a specific parametric model. The (tapered) periodogram may be used for a Whittle-type estimator leading to a corresponding test. Such a test-statistic, however, is not pivotal.

To address this difficulty, the authors introduce a transformation that leads to an asymptotic distribution, which is free of nuisance parameters. As a second result, the authors propose a bootstrap analogue of the transformation and confirm its validity. Third, the authors analyze linear parametric regression models, where x(t) is the (unobserved) additive noise component. These contributions provide a foundation for further study of such multidimensional spatiotemporal processes and a mechanism for their use in econometric work in many different applied fields.

The Tjalling C. Koopmans Econometric Theory Prize is kindly supported by the Cowles Foundation for Research in Economics. It is named in honor of Tjalling C. Koopmans, the 1975 Nobel Laureate in Economic Science. The prize is accompanied by a financial award of $1,000 to the winning author(s).
