This paper introduces the concepts of time-specific weak and strong cross section dependence. A double-indexed process is said to be cross sectionally weakly dependent at a given point in time, t, if its weighted average along the cross section dimension (N) converges to its expectation in...

In instrumental variable regression, structural parameter estimation relies on knowledge of the correlation between the structural error and the instruments. The current practice is to assume that this correlation is zero. However, this assumption is unlikely to be satisfied in applied work. In...

Currently, the commonly employed instrumental variables strategy relies on the knife-edge assumption of perfect exogeneity for valid inference. To make reliable inferences on the structural parameters under violations of exogeneity one must know the true correlation between the structural error...

This study constitutes an attempt to empirically evaluate, in a cross-country context, the respective roles of various theories of dynamic gains from trade liberalization in explaining observed positive impact of trade openness on development and agriculture sector and the prospected role of the...

In this paper, we consider the dynamic features of house price in metropolises that are characterised by a high degree of internationalisation. Using a generalised smooth transition (GSTAR) model we show that the dynamic symmetry in house price cycles is strongly rejected for the housing markets...

This paper examines the behaviour of house prices in large metropolitan areas. Using a sample of metropolises it is shown that real estate prices are largely nonlinear. It is found that dynamic asymmetries in the housing market cycle can well be modelled using a logistic smooth transition model...

Consider the duration of stay of migrants in a host country. We propose a statistical model of locally interdependent return hazards in order to examine whet- her interactions at the level of the neighbourhood are present and lead to social multipliers. To estimate this model we develop and...

Hierarchical analysis is considered and a multilevel model is presented in order to explore causality, chance and complexity in financial economics. A coupled system of models is used to describe multilevel interactions, consistent with market data: the lowest level is occupied by agents...

We discuss the finding that cross-sectional characteristic based models have yielded portfolios with higher excess monthly returns but lower risk than their arbitrage pricing theory counterparts in an analysis of equity returns of stocks listed on the JSE. Under the assumption of general...

This paper reviews the relationship between international investment agreements (IIAs) and foreign direct investment (FDI). It is organised in two parts. The first part explores the generic structure of IIAs and highlights the components that are particularly relevant to FDI. It then gives an...
