A General Misspecification Test for Spatial Regression Models: Dependence, Heterogeneity, and Nonlinearity

There is an increasing awareness of the potentials of nonlinear modeling in regional science. This can be explained partly by the recognition of the limitations of conventional equilibrium models in complex situations, and also by the easy availability and accessibility of sophisticated computational techniques. Among the class of nonlinear models, dynamic variants based on, for example, chaos theory stand out as an interesting approach. However, the operational significance of such approaches is still rather limited and a rigorous statistical-econometric treatment of nonlinear dynamic modeling experiments is lacking. Against this background this paper is concerned with a methodological and empirical analysis of a general misspecification test for spatial regression models that is expected to have power against nonlinearity, spatial dependence, and heteroskedasticity. The paper seeks to break new research ground by linking the classical diagnostic tools developed in spatial econometrics to a misspecification test derived directly from chaos theory—the BDS test, developed by Brock, Dechert, and Scheinkman (1987). A spatial variant of the BDS test is introduced and applied in the context of two examples of spatial process models, one of which is concerned with the spatial distribution of regional investments in The Netherlands, the other with spatial crime patterns in Columbus, Ohio.

The Nautical Archaeology of Puerto Rico

The waters of Puerto Rico harbour the remains of thousands of years of human occupation. The island played a key role in the first decades of European exploration of the New World, and its coasts and estuaries have preserved an extensive record of the island's maritime history, before and after the arrival of the Europeans. The objective of this project is to study Puerto Rico's seafaring history through the investigation of its submerged cultural heritage, with a particular focus on the history of European shipbuilding. In 2008 the authors started with survey on the north coast.

Cooperation without Trust: Overcoming Collective Action Barriers to Endangered Species Protection

Mutual trust among individuals is frequently cited as an important factor in encouraging collective action, particularly in environmental policy settings. Yet the precise role of trust in the collective action process remains uncertain. This article explores the hypothesis that trust is overrated as a cause of cooperation. It initially tests this hypothesis through two case studies of voluntary collective action in a new context: the creation of multiactor Habitat Conservation Plans to protect endangered species. The two cases suggest that institutional mechanisms and political leadership can play an important role in encouraging collective action without relying on trust among cooperators. Besides their theoretical implications, the results suggest policymakers might spend more energy on creating incentives and assurance mechanisms to encourage collaboration, rather than the potentially fruitless task of building of social capital among rival stakeholders.
