We show that, in a large class of models, market frictions lead to predictable dynamic patterns of the acquisition and subsequent shedding of inputs by firms. The logic is as follows. During high demand and expansionary periods, firms that fail to have inputs (machinery, labor, space, credit) in...

We show in this paper how the characteristics of fire recurrency in forests can be theoretically derived from simple informations concerning forest morphology. The task is accomplished by means of a minimal model encapsulating a few assumptions on the interactions between overstorey and...

Six Poisson autoregressive models of order p[PAR(p)] of daily wildland arson ignition counts are estimated for five locations in Florida (1994-2001). In addition, a fixed effects time-series Poisson model of annual arson counts is estimated for all Florida counties (1995-2001). PAR(p) model...

Wildfires’ increasing growth and spread have prompted aggressive approaches to fighting fire. The techniques used by firefighters can cause great damage to timberlands. Yet, there is currently no external review of the efficiency, costs, or impacts of various firefighting techniques....

Fire danger systems have evolved from qualitative indices, to process-driven deterministic models of fire behavior and growth, to data-driven stochastic models of fire occurrence and simulation systems. However, there has often been little overlap or connectivity in these frameworks, and...
