The American System was implemented by the US government after the American-British War of 1812 to develop a national domestic market. This study explores the rise and fall of the system between its inception in 1790 and the Panic of 1837. Ha argues that the American System started as an expression of American nationalism but resulted in intensifying sectional conflicts within the young republic. It was only implemented in minor cases and a truly national market failed to emerge. In 1840, the South bought just 8 per cent of the East's production and even less of the West's. Focusing on the...

Recent attention in the study of sign pattern matrices is the characterization of sign pattern matrices that require algebraic positivity and the characterization of sign pattern matrices that allow algebraic positivity.In this book we study the conditions for sign pattern matrices of order 2 and 3 to allow algebraic positivity, and apply them to the sign controllability of linear control systems.We first give a necessary condition for sign pattern matrices to allow algebraic positivity and, based on this fact, characterize all spectrally arbitrary sign pattern matrices that allow algebraic...
