There is significant policy interest in liquid biofuels with appealing prospects for energy security, farm security, poverty alleviation, and climate change. Large-scale commercial biofuel production could have far reaching implications for regional and global markets – particularly those related to energy and land use. As such, large-scale biofuels growth is likely to have significant impacts on global greenhouse gas (GHG) emissions. This paper utilizes a CGE model with explicit biofuel, land, and energy markets. The model is able to estimate the effects on the broad range of input and output markets potentially affected globally by biofuels policies. One of the most controversial issues within the biofuels debate is potential indirect changes in land use... |

Several papers have now estimated the impact of climate change on national timber markets, but few studies have measured impacts globally. Further, the literature on impacts has focused heavily on changes in productivity and has not integrated movements of biomes as well. Here, a dynamic model of ecological change and economic change is developed to capture the impact of climate change on world timber markets. Climate change is predicted to increase global timber production as producers in low-mid latitude forests react quickly with more productive short-rotation plantations, driving down timber prices. Producers in mid-high latitude forests, in contrast, are likely to be hurt by the lower prices, dieback, and slower productivity increases because of... |

We use the contingent valuation method to estimate participant willingness to pay for agricultural economics extension programming. The data, collected as part of standard evaluation forms for the Ohio State University's 2001 Agricultural Outlook and Policy program series, and subsequent analysis suggest participant benefits exceeded departmental costs of conducting the program (benefit-cost ratios of 1.07 under conservative assumptions and 1.74 under moderate assumptions). We also use the data to explore the revenue generation potential from alternative program pricing and discuss the potential for developing differentiated programs to reach distinct audience segments. Additional research necessary before implementing alternative pricing or program... |

This paper examines the competitiveness of the US timber industry under different exchange rate policies using a dynamic optimization model of global timber markets. We assume that exchange rates affect the cost structure of harvesting and managing forests and simulate the model for baseline conditions and four additional exchange rate policies. Two policies consider a strengthening United States dollar scenario and two policies examine weak South American currencies. Recently South America has increased its share of global timber production and is shipping increasing quantities of timber to the Unites States. The results indicate that US competitiveness in the forestry sector is sensitive both to strong US $ policies and to the weak currency policies... |

Over the past few years, interest in bioenergy has boomed with higher oil prices and concerns about energy security, farm incomes, and mitigation of climate change. In the same time, there is significant interest in international agricultural and forestry based greenhouse gas (GHG) mitigation. However, bioenergy and climate policies are being formulated largely independent of one another. Understanding the interaction between these potentially competing policy objectives is valuable for identifying possible constraints that one policy might be placing on the other, as well as potential complementarities. Using a general equilibrium framework, this study assesses the effects of bioenergy expansion on sectoral, regional and global GHG emissions mitigation... |

This paper develops a dynamic model of land, crop, and residue management choices in a typical Midwestern farm region. Carbon renting policy is implemented with alternative assumptions about relative crop prices. Model results show following results. First, crop choice between corn and soybean within a scenario does not appear to be sensitive to carbon prices. Second, residue management and carbon storage depend on crop prices and total carbon storage in soil is the greatest when more land is maintained in soybean. Third, there would be 4-7% increase in carbon per hectare with $3 per ton carbon price, 13-23% increase with $10 per ton carbon price, and 31-55% increase in carbon storage with $40 per ton carbon price. |

Competing risks survival analysis is used to investigate tax and zoning policy impacts on residential, commercial, and industrial development timing in a rapidly growing Midwestern county. Industrial development appears both to precede and occur concurrently with residential development, while commercial development follows other types. Although residences appear to locate away from industrial land, zoning decisions favoring industry may attract rather than deter residential development within a jurisdiction. Regions with higher infrastructure taxes experience development later. Because school taxes fund local public goods important to homeowners, they have little influence on residential timing, but strong influences on industrial and commercial timing. |

This study explores how property taxes affect the timing of development. The theoretical literature suggests that higher taxes increase the time to development, although there is some disagreement in the literature. We present a simple theoretical model to motivate an empirical model that explores how land use change decisions are made over time. A hazard model is used to predict factors that influence the time to development over an 11-year period in an urbanizing county in the Midwestern corn belt. The results suggest that higher taxes slow development, as expected. Over the 11-year period for our sample, we predict that 25% more agricultural land would have converted to development if taxes had not risen. We also find, however, that the effects are... |

In this paper, we compare and contrast two types of timber models that have been used for public policy analysis. These models have been variously used to predict price, inventory and market welfare impacts under different exogenous forces that impact timber markets. The framework and theory for each model type is presented and discussed. We then thoroughly test the two model types across six potential exogenous shocks to timber markets, ranging from instantaneous demand shocks to gradual supply adjustments. Our comparison indicates that these models predict potentially important differences in timber market behavior. These differences are important to consider for those who do public policy analysis. |
