Recently, several articles appeared on the location–design problem that firms face when entering a competing market. All use a Huff-like attraction model. We discuss the formulation of the base model, the different settings studied in the papers and summarise their findings.

spatial competition between stores of the same brand, brand attraction based on actual brand performance and spatially variable substitution. The model uses only publicly available or easily acquirable data as input, whereas model output is extensively validated on various levels. These levels...

Recently gravity trade models are applied to disaggregated trade data. Here many zeros are characteristic. In the presence of excess zeros usual Poisson Pseudo Maximum Likelihood (PPML) is still consistent, the variance covariance matrix however is invalid. Correct economic interpretation...

Singapore?s outward FDI is peculiar in important respects, even though it shares some characteristics with FDI undertaken by traditional investor countries. The focus of FDI in the manufacturing sector on lower-income Asian host countries suggests that the motivations and trade repercussions of...

The deepening of the Barcelona Agreement and the discussions of the creation of a Mediterranean Union has awakened the interest of the non-EU Mediterranean countries to expand their exports to the European markets. This study analyses the factors that influence the German imports of olive oil by...

Well anchored inflation expectations are considered to be a reflection of credible monetary policy. In the past, anchoring has been assessed using either long-run inflation surveys or break-even inflation rates on financial assets with long maturities. But neither of these is ideal. Here we...

In this paper we solve the gravity (Huff) model for the competitive facility location problem. We show that the generalized Weiszfeld procedure converges to a local maximum or a saddle point. We also devise a global optimization procedure that finds the optimal solution within a given accuracy....

The location of first generation processing plants for biogas using bulky inputs is a prominent example of locational decisions of plants that face high per unit transport costs of feedstock and simultaneously depend to a large extent on feedstock availability. Modelling the resulting regional...
