The use of equilibrium formulations in urban modelling is increasingly challenged by models that explicitly address the dynamics of urban change. Equilibrium models assume that urban land use and transport converge to equilibrium between supply and demand and focus on comparative static analysis...

We develop a simple two-region, cobweb-type dynamic equilibrium model to demonstrate the existence of optimal trade barriers. A pure comparative statics analysis of our model suggests that a reduction of trade barriers always enhances welfare. However, taking a dynamic perspective reveals that...

Planning as deliberate preparation for future action is as old as human history. Agricultural land allocation and cities were always planned, as were military warfare and defence. With the growing complexity of society in the 19th century, however, planning became a discipline and profession....

We extend an aggregative growth model for a small open economy by developing a framework in which boundedly rational agents raise credit in proportion to their expected income. Moreover, these agents are heterogeneous in the sense that they switch between an extrapolative and a regressive...

Metzler's model is an important contribution to our understanding of the dynamics of business cycles. In his model, the production of consumption goods depends on expected future sales. However, Metzler assumes that producers are homogeneous and follow a simple expectation formation rule. Taking...

The important role of transport infrastructure for regional development is one of the fundamental principles of regional economics. In its most simplified form it implies that regions with better access to locations of input materials and markets will, ceteris paribus, be more productive, more...

Selected results of a multilevel dynamic simulation model of the economic and demographic development of the urban region of Dortmund are presented. In particular, the capability of the model to capture both urban growth and urban decline processes is illustrated. The mechanisms that control...
