This paper examines trends in annual temperature data for the northern and southern hemisphere (1850-2010) by using variants of the shifting-mean autoregressive (SM-AR) model of González and Teräsvirta (2008). Univariate models are first fitted to each series by using the so called QuickShift...

The linearity of the U.S. hog-corn cycle has been questioned by Chavas and Holt (1991). Even so, attempts have not been made to model the potential nonlinear dynamics in the hog-corn cycle by using regime-switching models. One popular alternative is Terasvirta's smooth transition autoregressive...

The linearity of the U.S. hog corn cycle has been questioned by . Even so, attempts have not been made to model the potential nonlinear dynamics in the hog corn cycle by using regime-switching models. One popular alternative is smooth transition autoregressive (STAR) model, which assumes regime...

This paper examines the role of mechanical refrigeration in temporal and spatial price relationships for regional egg markets in the United States, 1880–1911. Notably, this period encompasses an era in which widespread adoption of mechanical refrigeration greatly impacted the ability to...

In this dissertation, three related issues of building empirical time series models forfinancial markets are investigated with respect to contemporaneous causality, dynamics,and structural change. In the first essay, nation-wide industry information transmissionamong stock returns of ten sectors...
