Abstract Timberland ownership has drastically changed in the United States since the 1980s, driven by the divestitures of vertically integrated forest products companies. Having sold their timberland, forest products companies have exposed themselves more to the risk of raw material supply. To hedge against this risk, forest products companies usually use long-term timber contracts (LTTC). The objective of this article is to update the valuation framework for LTTCs proposed by Shaffer (1984) by including alternative option price models and refining the estimates of some key economic variables. In particular, conditional volatility from the generalized autoregressive conditional heteroscedasticity model and quasi-conditional volatility from rolling estimation windows, in addition to simple standard deviation, are used for the volatility estimates in the option pricing models. Contrary to the previous result by Shaffer (1984), our analysis suggests that LTTCs that were once profitable for forest products companies in the 1980s are no longer so under current market conditions. This is primarily because both timber price volatility and the risk-free interest rates have declined significantly. Thus, to be better off, forest products companies need to either lower the administration and management costs of those LTTCs or rely more on the open market for timber procurement. Study Implications: Forest products companies have traditionally relied on long-term timber contracts (LTTC) negotiated with forest landowners to mitigate the risk of raw material supply. The value of these LTTCs highly depends on the economic context. This research provides some insights into the valuation of LTTCs in the southeastern United States. Forest products companies can use this updated framework to aid their decisionmaking in timber procurement.

Histological Evidence

Cylindrocladium pseudonaviculatum, the causal agent of box blight, has been shown to survive in soil for at least 5 years. The occurrence of microsclerotia in host tissue remains undocumented, making the mechanism for long term survival of this pathogen unclear. If the boxwood blight pathogen has indeed lost or never evolved the ability to produce microslerotia in tissues, one could infer that the pathogen is either less equipped for long term survival in soil than other Cylindrocladium species or the pathogen has evolved another mechanism to enable it to persist in soil. Based on these assumptions, we conducted a histological study to determine the potential role, if any, of microsclerotia in the lifecycle of C. pseudonaviculatum.

This chapter considers the history of Social Security, arguing that the 1950 amendments represented the fundamental adjustment that allowed the program’s long-term survival. It analyzes current issues in Social Security related to gender, race, and the program’s long-term solvency. It concludes that Social Security has legitimized the receipt of government benefits among many Americans and changed the nature of old age in the United States by providing older people with a guaranteed means of support. A large and costly program, Social Security has evolved into the United States’ major antipoverty program. Nonetheless it faces the criticism of those who argue that it favors older people over other age groups and that it represents an inefficient form of government coercion. Whether the program will be sustained in the future or modified in a significant way remains a critical question.

Construction Of Whiteness

These two fascinating articles seek to fill an important lacuna in the burgeoning literature on the legal construction of whiteness. While LatCrit theorists in the legal academy have urged civil rights scholars and race critics to transcend the “black-white paradigm” of U.S. race studies, the majority of legal histories of whiteness have focused on two sets of cases: trials in the southeastern United States in which local courts tried to draw the line between “white” and “negro”; and cases about immigration and naturalization in which Federal courts determined whether particular foreign immigrants were suitably “white” for citizenship. Likewise, although there have been several important social and cultural histories of Texas Mexicans and whiteness in the last fifteen years, they have not considered the legal realm. The time is ripe for attention to the legal history of Mexican Americans' civil rights struggles in Texas, especially as they illuminate the shifting racial identity of Mexican Americans in the Southwest.
