GMM Estimation of Spatial Autoregressive Models with Moving Average Disturbances

Taspinar, Suleyman - 2017

In this paper, we introduce the one-step generalized method of moments (GMM) estimation methods considered in Lee (2007a) and Liu, Lee, and Bollinger (2010) to a spatial autoregressive model that has a spatial moving average process in the disturbance term (for short SARMA (1,1)). First, we...

Integrating Gravity : Therole of Scale Invariance in Gravity Models of Spatial Interactions and Trade

Arvis, Jean-François - 2017

This paper revisits the ubiquitous bi-proportional gravity model and investigates the reasons why different theoretical frameworks may lead to the same empirical formula. The generic gravity equation possesses scale invariance symmetries that constrain possible theoretical explanations based on...

Understanding Unobserved Propensities of Suicide in the United States : A Hierarchial Model with Spatially Correlated Random Effects

Sung, Jaesang - 2017

This paper investigates the underlying causes of suicide. In contrast to previous literature, we use data from the United States at the county level. Our primary methodology is a two-level Bayesian hierarchical model with spatially correlated random effects. Our results show that the significant...

Spatial Competition with Interacting Agents

Ottino-Loffler, Bertrand; Stonedahl, Forrest; Veetil, … - 2017

We generalize Hotelling’s model of spatial competition with more than two firms in a two-dimensional space. Firms choose both price and location to maximize profits. The principle of minimum differentiation does not hold in general. Local duopolies emerge from the interaction between firms....

Network effects on labor contracts of internal migrants in China : a spatial autoregressive model

Baltagi, Badi H.; Deng, Ying; Ma, Xiangjun - 2017

This paper studies the fact that 37 percent of the internal migrants in China do not sign a labor contract with their employers, as revealed in a nationwide survey. These contract-free jobs pay lower hourly wages, require longer weekly work hours, and provide less insurance or on-the-job...

Spatial regression-based model specifications for exogenous and endogenous spatial interaction

Fischer, Manfred M; LeSage, James P. - 2014

Spatial interaction models represent a class of models that are used for modelling origin-destination flow data. The …-spatial and endogenous spatial interaction models and associated scalar summary measures from Thomas-Agnan and LeSage (2014), we … propose new scalar summary measures for the exogenous spatial interaction specification introduced here. An illustration …
