Assuming a competitive market, conditions are determined for when a steady-state equilibrium does not exist in the optimal dynamic management of a biological population. Irregular and unpredictable behavior (called “"chaos"”) can arise from fully rational economic decision making. High...

This paper investigates the nonlinear dynamic response to shocks, relying on a threshold quantile autoregression (TQAR) model as a flexible representation of stochastic dynamics. The TQAR model can identify zones of stability/instability and characterize resilience and traps. Resilience means...

Time series analysis of commodity prices is one of the ongoing developments in relevant empirical studies. The usual research questions are what causes a certain price behavior and what are the consequences. As causes and consequences are sequential events, time is the natural domain of...

This chapter reviews the specification and application of the Deaton and Muellbauer (1980) Almost Ideal Demand System (AIDS) and the Christensen, Jorgensen, and Lau (1975) tranlog (TL) demand system. In so doing we examine various refinements to these models, including ways of incorporating...

This paper explores the role of structural change in systems of demand equations. Specifically, we adapt the time—varying regression framework of Lin and Teräsvirta (1994), which in turn is related to the dynamic smooth transition models introduced by Teräsvirta (1994). Unlike previous...

Price dynamics for North American oriented strand board (OSB) markets are examined. The role of transactions costs are explored vis-a-vis the law of one price. Weekly data, February 3rd, 1995 through October 9th, 2009, are used in the analysis. Nonlinearities induced by unobservable transactions...

This paper explores the behavior of real commodity prices over a 50–year period. Attention is given to how the fundamentals for various commodity prices have changed with a special emphasis on behavior since the mid 2000s. To identify changing commodity price fundamentals we estimate...

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...
