| This paper presents the results of a preliminary intercept survey of consumers at farmers' markets in Gainesville, Florida in 2007. We developed survey questions to identify: (1) how much fruit and vegetable produce respondents buy from local sources; (2) attitudes regarding local foods; (3) definitions of local by distance and ownership; (4) WTP for local foods; (5) perceptions of the availability and cost of local products; and (6) demographic information. In addition to WTP, we employed several tools- a Likert scale, a cost/availability matrix, and other investigatory and demographic questions - to analyze factors affecting purchasing decisions. These include relative cost, accessibility, attitudes and perceptions of the term 'local.' We report and... |

| Courts are often required to estimate changes in welfare to agricultural operations from catastrophic events. For example, courts must assign damages in lawsuits, such as with pesticide drift cases, or determine "just compensation" when the government takes private land for public use, as with the removal of dairy farms from environmentally sensitive land or destruction of canker-contaminated citrus trees. In economics, the traditional method of quantifying producer losses is estimating changes in producer welfare, but courts rarely use this method. Instead, they turn to substitute valuation methods that may not fully capture welfare changes, such as changes in land value, tree replacement value, and total revenue. This study examines various measures for... |

| The invasive aquatic plants Hydrilla verticillata (hydrilla), Eichhornia crassipes (water hyacinth), and Pistia stratiotes (water lettuce) have the potential to negatively impact recreational use of Florida lakes if consistent, adequate control expenditures are not made. In the mid-1990's, Florida significantly reduced its spending on invasive aquatic plant control measures, which resulted in a significant increase in needed control expenditures in subsequent years. This paper attempts to formalize a relationship between coverage of these invasive aquatic plants and angler effort on Florida lakes using data on 38 lakes over 20 years. Estimated regression coefficients are used to simulate control alternatives, and expenditure cost-benefit comparisons are... |

| European Union (EU) consumers pay almost twice the competitive world price for many agricultural products. Agricultural subsidies accounted for almost half of the EU's total budget (US$ 40 billion on agriculture in 2000) although agriculture represented 1.7 percent of the EU's GDP and employs 4.3% of the EU's population. Domestic policies for citrus and tomatoes include export refunds, product withdraws from the market, intervention thresholds, and direct producer aid. Domestic policies for dairy include export refunds, intervention thresholds, aid for private storage, disposal aid, and milk quotas. The EU's intentions are to enhance agricultural competitiveness by setting product intervention as "a real safety net measure, allowing EU producers to respond... |

| This study examines the impact of invasive plants on recreational activities on Floridas coastal, freshwater and upland natural areas using a multi-attribute utility (MAU) model. Six MAU surveys were electronically distributed to Florida residents in early 2007. We specified a conditional Logit model to estimate the relative weights associated with a change in Fees, Invasive Species, Native Animal Species, Native Plant Species, and Facilities. Using Fees as a payment vehicle, we estimate the average Florida residents marginal willingness to pay for changes to attributes, including having fewer invasive plants and more positive attributes such as facilities and the presence of native animal and plant species. Florida residents have a marginal willingness... |

| We present a bioeconomic model of three invasive aquatic plants (hydrilla, water hyacinth, and water lettuce) in 13 large Florida lakes, and simulate one-year and steady-state impacts of three control scenarios. We estimate that the steady-state annual net benefit of invasive plant control is $59.95 million. A one-year increase in control yields steady-state gains of $6.55 million per year, and a one-year lapse causes steady-state annual losses of $18.71 million. This model shows that increased control of hydrilla, water hyacinth, and water lettuce is optimal. |
