An Analysis Of The Iowan Angler's Fishing License Renewal Decision, Ryan R. French Jan 2006

An Analysis Of The Iowan Angler's Fishing License Renewal Decision, Ryan R. French

Retrospective Theses and Dissertations

The number of annual fishing licenses sold in Iowa has been in decline for two decades and has limited the amount of funds available to the Iowa Department of Natural Resources for fisheries management. The Iowa DNR is focused on reversing this trend through targeted marketing and efficient management of fishing resources. An analysis of Iowa anglers is performed with these goals in mind using past surveys and current customer data. The product of this analysis is a model which predicts whether a past customer will renew their license in the upcoming year. A logit model is developed using license ...


Agricultural And Trade Policy Reform In Mexico: Procampo, Nafta, And Pre-Gatt , James Mark Hansen Jan 2000

Agricultural And Trade Policy Reform In Mexico: Procampo, Nafta, And Pre-Gatt , James Mark Hansen

Retrospective Theses and Dissertations

Changes in Mexico's domestic agricultural policy (PROCAMPO) and continued liberalization of trade through GATT and NAFTA have had strong effects on Mexico's agricultural production, consumption, and trade with the United States. The main objective of this study is to analyze these effects in Mexico's grain and livestock sectors. Policies within the NAFTA and GATT international trade agreements may overlap to some degree, and Mexico's domestic agricultural liberalization program (PROCAMPO) may include policies that overlap those in one or both of the international trade agreements. This study analyzes the effects of PROCAMPO, NAFTA, and pre-GATT policies compared ...


The Determinants Of Rural Population Growth And Decline, 1950-1990: The Roles Of Government Policy, Human Capital, And Farm And Nonfarm Income , Tzu-Ling Huang Jan 1996

The Determinants Of Rural Population Growth And Decline, 1950-1990: The Roles Of Government Policy, Human Capital, And Farm And Nonfarm Income , Tzu-Ling Huang

Retrospective Theses and Dissertations

In the past few decades, changes in economic conditions for off-farm labor markets and improvements in agriculture technology have led to substantial reductions in farm population in the United States. However, rural populations are not decreasing uniformly, either across counties or over decades. Rates of change in farm and nonfarm populations vary widely across rural counties. The variation of population growth across counties and between farm and nonfarm population raise two questions in this study: (1) What affects the population growth and decline in US rural counties? (2) Do those factors affect farm and nonfarm populations differently?;This study is ...

An Economic Investigation Into Railroad Pricing And Car Allocation Programs , Gregory Roy Pautsch

Retrospective Theses and Dissertations

The movement of grain by the railroad industry is plagued by the consistent presence of car shortages and surpluses. Due to these difficulties and others the Staggers Rail Act of 1980 was passed;In the pre-Staggers system, the railroad chooses its tariff and capacity before knowing demand which creates the persistent cycle of car shortages and car surpluses. Shippers order conventional rail service, with full information, on a spot basis;Recently, railroads have instituted car ordering systems offering guaranteed service as well as conventional tariff service. Guaranteed service is ordered by shippers in advance and before possessing full grain market ...


Effects Of Farm Characteristics And Government Disaster Assistance On Multiple-Peril Crop Insurance Purchases By Iowa Crop Farmers , Khosrow Khojasteh Jan 1992

Effects Of Farm Characteristics And Government Disaster Assistance On Multiple-Peril Crop Insurance Purchases By Iowa Crop Farmers , Khosrow Khojasteh

Retrospective Theses and Dissertations

The present federal crop insurance program has been characterized by low farmer participation and high government costs. It has been frequently argued that one of the major factors causing the poor participation rate is the continued availability of disaster relief payments, whereby the ad hoc disaster assistance programs help support producers' beliefs that a widespread natural disaster will be accompanied by government assistance;The purpose of this study was to develop and empirically estimate probability models that could explain Iowa farmers' behavior regarding the purchase of multiple-peril crop insurance. The models under study included both linear and nonlinear single- equations ...
