The Jordan Form of the VAR's Companion matrix is used for proving the equivalence between the statement that there are no jordan blocks of order two or higher in the Jordan matrix and the conditions of Granger's Representation Theorem for an I(1) series. Furthermore, a Diagonal polynomial matrix...

This paper discusses a liquidity run model where investors optimally decide whether or not to acquire private information. This endogenizes the dichotomy "private information/no private information". The price of the information makes the equilibrium partitioning of the fundamentals two...

In order to understand the dynamic effects of government spending on foreign trade the present paper proceeds in two steps. First, using U.S. time series data for the post-Bretton-Woods period, the dynamic effects of government spending are investigated within a structural Vector Autoregression...

We model the impact of different modes of multinational entry on the choices of domestic firms. Focusing on the competitive effects of foreign presence in the host country we demonstrate that greenfield investment will increase competition only if it is not countered by anti-competitive...

The vector autoregressive model for seasonal cointegration is analysed. The general error correction model is discussed and conditions are found under which the process is integrated of order 1 at seasonal frequency and exhibits cointegration. Under these conditions a representation theorem for...

There are still problems in handling diversity in economics. The general equilibrium model itself lacks determinacy for a generic population of economic agents. In an ourstanding contribution, Jean-Michel Grandmont (1992) argues that increasing behavioural heterogeneity makes aggregate...

Wholesale trade affiliates account for a considerable fraction of the sales of Multinational Companies (MNCs). However, this and similar types of FDI, aiming at facilitating export activities, have received little attention in the literature. In this paper export-supporting FDI (ESFDI) which is...

Experimental evidence from modified dictator games and simple choice situations indicates that concern for overall welfare is an important motive in human decision making. Models of inequality averse agents, as suggested by Fehr and Schmidt (1999) or Bolton and Ockenfels (2000), fall short in...
