The paper considers the use of directed acyclic graphs (DAGs), and their construction from observational data with PC-algorithm TETRAD II, in providing over-identifying restrictions on the innovations from a vector autoregression. Results from Sims' 1986 model of the US economy are replicated...

Empirical evidence linking exports to economic growth has been mixed and inconclusive. This study re-examines the export-led growth (ELG) hypothesis for Canada by testing for Granger causality from exports to national output growth using vector error correction models (VECM) and the augmented...

Existing empirical evidence on the impact of macroeconomic variables on agriculture remains mixed and inconclusive. This paper re-examines the dynamic relationship between monetary policy variables and agricultural prices using alternative vector autoregression (VAR) type model specifications....

The U.S. broiler industry is highly vertically integrated and increasingly concentrated in the number of firms and production areas. These structural elements could have implications for performance and the functioning of the law of one price (LOP) across regions. This article investigates this...

Using GMM models on a panel data of fifty-three countries, we examine whether stronger foreign IPR protection stimulates international transactions of U.S. multinational firms. The empirical results suggest that foreign countries that strengthen their IPR protection, especially those with strong...

The knowledge-capital (KC) model of MNEs is now a widely adopted empirical approach to explaining the location and production decisions of global firms based on both horizontal and vertical motivations. While most of the existing studies have focused on highly aggregated national data, we extend...
