This paper aims at providing new insights into dynaraic spatial interaction and I-O analysis by linking a multiple objective programming approach to stochastic dynaraic spatial allocation models. In this context, a multiple objective optimal control model is designed, which appears to lead to a generalized solution for conventional spatial interaction problems. Next, by using a Wiener (or Brown...

Since the late 1970s, China’s government has gradually eased restrictions on internal migration. The easing of restrictions, along with rapid growth of the Chinese economy, the forces of globalization, and substantial increases in foreign direct investment and local construction spending, have greatly stimulated internal migration. The recent availability of Chinese migration data for three dif...

The misspecification of gravity spatial interaction models has recently been described by the author. The bias in parameter estimates that results from such misspecification appears to produce the 'map pattern effect' or 'spatial structure bias' in estimated distance-decay parameters. A further aspect of the misspecification bias in gravity parameter estimates is explored here. The severity of ...

In 2004 the EU faced its most extensive enlargement ever when ten new countries joined. One can speculate about the reasons for these countries to join the EU and one suggestion that is often found is the access to a larger market and the trade possibilities that would entail; the customs union effect. Therefore this thesis sets out to investigate whether this is plausible; do countries trade m...

This paper examines the effect of immigration on the US trade flows. The model hypothesizes that immigration facilitates international trade with home countries by lowering transaction costs. Immigrants also demand products from their country of origin, and thus stimulate trade. Using a panel data set I estimate a dynamic, fixed-effect model. The immigrant stock, a proxy for transaction costs, ...

The paper presents accurate numerical solutions of the full two-dimensional governing equations for steady and unsteady laminar/laminar internal condensing flows. The results relate to issues of better design and integration of condenser-sections in thermal management systems (looped heat pipes, etc.). The flow geometry, in normal or zero gravity, is chosen to be the inside of a channel with fi...

One of the main concerns of researchers is the separation of suspended particles in a fluid. Accordingly, the current study numerically investigated the effects of a conical section on the flow pattern of a Stairmand cyclone by simulating single-cone and dual-cone cyclones. A turbulence model was used to analyze incompressible gas-particle flow in the cyclone models, and the Eulerian–Lagrangian...

regional agreements can facilitate the integration of world economies by opening the borders to the trade development while accelerating technological changes and maintaining the economic growth. trade potential is defined as the trade that could be achieved at an optimum trade frontier with the open and frictionless trade possible through regional agreements based on the current level of trade...
