| The paper extends the work of Deller et al (2001) by introducing a spatial component in a structural growth model to capture the role of spatially distributed variables using county-level data. The premise of the analysis is that what is true at a national level may provide a partial or misleading picture when we look at particular areas. Additionally, data available at the state level can often provide richer, more precise information than what is found at the national level, so we try to explore in more depth the role of spatially distributed amenities in economic development by examining, for instance the valuable Alabama countryside features such as natural habitats, scenic landscapes and warm weather amidst a poverty of infrastructure. The estimated... |

| This paper estimates a demand system for a selected tropical fresh fruit and vegetable imports in to the U.S. using a Linear Approximate Almost Ideal Demand Systems model for the period 1989-2008. Further the paper attempts to capture trade policy and seasonality effects that affect the demand for fresh fruit and vegetable imports. Results show that most of the price elasticities of demand have the expected signs and less than unity magnitude except for tomatoes. Complimentary commodities include bananas and papayas, grapes, and mangoes, peppers and tomatoes and avocados, and tomatoes and cucumber. Substitutes include pineapples and papayas, grapes and papayas, and mangoes and tomatoes. Trade policy and seasonality are also found to affect fresh fruit and... |

| A source-differentiated Almost Ideal Demand System model is used to analyze U.S. demand for the major tropical fresh fruit imports from different countries of origin. The tropical fresh fruits chosen for analysis include fresh bananas, fresh pineapples, papayas, and mangoes/guavas. To address endogeneity problem, we utilized an iterative 3SLS estimation method. Results show that consumer incomes are a major determinant of tropical fresh fruit import demand and most of the tropical fresh fruit imports are luxury commodities. U.S. consumers have a preference for Guatemalan and Costa Rican bananas, Costa Rican and Honduras pineapples, and Ecuador and Mexican mangoes. A competitive relationship exists between bananas from Ecuador and Colombia, Ecuador and... |

| Most agricultural production results in both marketable and non-marketable products. Most policy decisions however, tend to be made based only on the market value, which ignores the non-marketable value or amenity benefits. One type of amenity benefits is farmland amenities which are attributes of farmland that are uniquely provided by actively farmed land. Examples include the scenic beauty of rolling pasture, orchards and the cultural value of farming as a way of life. Farmland also produces non-farm amenities, such as open space, wildlife habitats, and groundwater recharge. Most amenity benefits are classified as public goods in that they are non-excludable and non-rival in terms of use. Thus, most amenities do not have a market value associated with... |

| Job satisfaction is an important measure of utility that employees derive from their jobs and is related to various features of the job such as pay, security, intrinsic values of work, working conditions, career growth opportunities, working hours, and the like. This paper analyzes the relationship between underemployment and overall job satisfaction among other personal and job characteristics of the workforce in Alabama using survey data from Alabama workforce development regions. A logistic model is used to analyze the determinants of job satisfaction in Alabama including underemployment. Estimation results show a negative relationship between underemployment and job satisfaction. Personal and work-related attributes such as education, age, work hours,... |
