Price dynamics for North American oriented strand board markets are examined. The role of transactions costs are explored vis-à-vis the law of one price. Nonlinearities induced by unobservable transactions costs are modeled by estimating time-varying smooth transition autoregressions...

This paper explores the behavior of real commodity prices over a 50--year period. Attention is given to how the shifting means for various commodity prices have changed with a special emphasis on behavior since the mid 2000s. To identify structural changes in commodity prices, we estimate...

The linearity of the U.S. hog-corn cycle has been questioned by <link rid="b4">Chavas and Holt (1991)</link>. 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 <link rid="b43">Teräsvirta's</link> smooth transition autoregressive...

This article extends the recent literature on the Prebisch-Singer hypothesis of a long-run decline in the relative prices of primary commodities. Our main innovation is testing for and estimating nonlinear alternatives to a secular deterioration. Specifically, we use bootstrap procedures to test...

In recent years, the theoretical restrictions of consumer demand have been examined in post-sample forecasting exercises. However, this work has uniformly ignored associated curvature restrictions. In this paper we evaluate a series of Normalized Quadratic Inverse Demand System (NQIDS)...

Our main innovation is testing for and estimating nonlinear alternatives to a secular deterioration. Specifically, we use bootstrap procedures to test...

In this paper we introduce inverse demand systems that include quadratic scale terms. These systems are similar to regular quadratic demand systems introduced by Howe, Pollak, and Wales. A unique feature of these specifications is that they maintain linear scale curves as a special case. For...

The reaction of labor marketsto economic reforms is an important indicator of the progress of transition. Because of diminished government support and the breakup of state and collective enterprises, labor market adjustments in the transition economies have been particularly severe in the...
