Agricultural Productivity and Environmental Impacts: The Role of Non-parametric Analysis AgEcon
Shaik, Saleem; Perrin, Richard K..
Our contribution in this article is to compare two methods of adjusting agricultural productivity estimates for the effects of bad environmental outputs. One method is a direct non-parametric Malmquist index with the environmental variables include. The other method is to use the shadow prices from the Malmquist analysis to modify a Tornqvist-Theil with shadow shares for the environmental variables.

Agricultural Insurance as an Environmental Policy Tool AgEcon
Coble, Keith H.; Hanson, Terrill R.; Miller, J. Corey; Shaik, Saleem.
This paper examines the possibility that insurance for row crops, livestock, and aquaculture can be used effectively to encourage producers to adopt practices that will improve environmental behavior. Examples of agricultural environmental insurance are provided and considered in the context of alternative policy mechanisms. The current state of agricultural insurance and the nonagricultural environmental insurance market are explored. We also lay out the characteristics of an insurable risk along with the theoretical basis of insurance provision. An empirical example of an environmental insurance design is provided, and the behavioral implications of such a design are examined. Finally, we discuss important considerations that should be evaluated...

Increased Cocoa Bean Exports under Trade Liberalization: A Gravity Model Approach AgEcon
Yeboah, Osei-Agyeman; Shaik, Saleem; Wozniak, Shawn J.; Allen, Albert J..
Gravity models were developed to estimate the potential bilateral exports of cocoa under trade liberalization by the sixteen major cocoa producing countries to the US using panel data from 1989 to 2003. The results indicate that differences between resource endowment, relative size of economies, and the sum of bilateral GDP of U.S. and exporting countries are the major determinants. Thus, as trade is liberalized, farmers share of the world price of cocoa increases and this raises exports.

An Analysis of Trends in Food Import Refusals in the United States AgEcon
Allen, Albert J.; Myles, Albert E.; Shaik, Saleem; Yeboah, Osei-Agyeman.
Millions of pounds of fresh fruits, vegetables, cut flowers, herbs, and other agricultural and food products enter the United States via commercial shipments from other countries every year. Although these items appear harmless, there could be hidden threats in that baggage and in those truckloads, trainloads, and containers of fresh and processed food items that could seriously threaten U.S. agriculture, its natural resources, and its economy (U.S. Customs and Border Protection 2007). Food imports play a major role in the success and competitiveness of various agribusiness firms in the United States. For example, food imports generate income, employment, output, and taxes and provide consumers with lower-priced products than those produced or purchased in...

MEASURING SCOPE AND SCALE EFFICIENCY GAINS DUE TO SPECIALIZATION AgEcon
Helmers, Glenn A.; Langemeier, Michael R.; Shaik, Saleem.
Using the non-parametric linear programming approach, this study examines overall efficiency gains due to diversification between crop and livestock enterprises for a sample of Kansas farms. Overall efficiency gains were decomposed into scope efficiency gains and scale efficiency gains. Farms with both crops and livestock were found to be less efficient than farms with just crops or just livestock. Operator age, profit margin, and farm size were significantly related to overall efficiency.

The Trade Effects of MERCOSUR and The Andean Community on U.S. Cotton Exports to CBI countries AgEcon
Yeboah, Osei-Agyeman; Shaik, Saleem; Batson, Seon.
The United States engagement in nonreciprocal preferential trade arrangements has been proliferating with several developing countries throughout the past couple of decades. One of the oldest and more successful of these arrangements has been the Caribbean Basin Initiative (CBI).The CBI is a general term used to refer to the Caribbean Basin Economic Recovery Act of 1983 (CBERA), the Caribbean Basin Economic Recovery Expansion Act of 1990 (CBERA Expansion Act), and the Caribbean Basin Trade Partnership of 2000 (CBTPA) (Ozden and Sharma 2006). The central premise behind the plan was that, by encouraging the CBI countries to become more open and liberal, trade would expand – and eventually translate into economic development and growth (Deere, 1990). The...

Dynamic Relationships Between Farm Real Estate Values and Federal Farm Program Payments AgEcon
Shaik, Saleem; Miljkovic, Dragan.
This study examines the dynamic relationships among farm real estate values, farm returns, farm program payments, and real interest rates in an income capitalization model. Endogeneity is assumed among the variables in a dynamic framework because the direction of causality is unclear from a theoretical standpoint. The analysis encompasses the period beginning with the introduction of the first farm bill in 1933 and ending in 2006. Results indicate farm program payments have positive direct impacts in the short run and positive indirect impacts (via farm returns) in the long run on farm real estate values.

Trade Effects of the Central American Free Trade Agreement AgEcon
Yeboah, Osei-Agyeman; Shaik, Saleem; Allen, Albert J.; Ofori-Boadu, Victor.
Proponents of DR-CAFTA argue the RTA will free the U.S. agricultural sector of these disadvantages by leveling the field through the removal of these tariffs and in many cases, create preferences for U.S. exporters over third country suppliers, including those in Canada, Europe, and South America, helping to restore lost U.S. market share and expand overall U.S. exports. In this paper, we develop gravity models to estimate and predict the potential bilateral trade flows between U.S. and CAFTA countries using panel data. In the course of the study, it was expected that if DR-CAFTA were to have an effect, all countries under the agreement should be trade creators. All the six CAFTA countries but one (Costa Rica) are trade creators. The amount trade...

NON-PARAMETRIC ENVIRONMENTAL ADJUSTED PRODUCTIVITY (EAP) MEASURES: NEBRASKA AGRICULTURE SECTOR AgEcon
Shaik, Saleem; Perrin, Richard K..
Traditional Total factor productivity [TFP] misrepresents the true change in agricultural productivity because environmental bads jointly produced with desirable outputs are unaccounted. Nonparametric measures incorporating environmental bads support the hypothesis that prior [after] to 1980's the traditional TFP overstate [understate] production growths, reflecting peak use of chemicals.

Sensitivity of Rural Housing Values to Aggregate Economic Policy AgEcon
Shaik, Saleem; Gustafson, Cole R..
This paper has a two-fold contribution, 1) Examine the importance of aggregate economic policy on housing prices and rural housing prices, and 2) delineate factors resulting in divergent housing prices between urban and rural markets. Empirical application to US state level data from 1975-2006 indicates general economic variables are consistently influencing both urban and rural housing prices. While the farm economic variables do have differential influences on the housing and rural housing prices, their effects are transitory. Finally regional effects have greater impact on differential effects on urban rural housing price indexes than national farm programs.

Nature of Dynamic Relationships Between Farm Real Estate Values and Federal Farm Program Payments AgEcon
Shaik, Saleem; Miljkovic, Dragan.
The objective of this study is to test the dynamic relationships among variables including farm real estate values, farm returns, farm program payments, and real interest rates in an income capitalization model. Our analysis is unique in multiple ways: (1) it covers the period beginning with the introduction of the first farm bill in 1933 through 2006; (2) assumes endogeneity of the variables, and (3) develops a dynamic modeling framework. Endogeneity is assumed among farm real estate values, farm program payments, and farm receipts since the direction of causality is unclear from a theoretical standpoint. Results indicate that policy makers are reactive rather than pro-active in making transfers to farmers. Once farm program payments are implemented,...

TESTING FOR INPUT AND OUTPUT SEPARABILITY IN NEBRASKA AGRICULTURE SECTOR AgEcon
Shaik, Saleem; Helmers, Glenn A..
The existence of Weak Separability aggregates of inputs and outputs is tested using a Translog production and input requirement function for the Nebraska Agricultural sector for 1936-1994. A separability test was performed only after testing time series properties by comparing the null hypothesis of stationarity against the alternative of unit roots.

SHADOW PRICE OF ENVIRONMENTAL BADS: WEAK VS. STRONG DISPOSABILITY AgEcon
Shaik, Saleem; Helmers, Glenn A..
This paper addresses the issue of the shadow price of environmental bads treated as an undesirable output (normal input) with weak (strong) disposability in a two-stage estimation. Nebraska agriculture sector time series data used is spread over 1936-94. Results indicate the difference in the price due to the disposability property.

Exchange Rates Impacts on Agricultural Inputs Prices using VAR AgEcon
Yeboah, Osei-Agyeman; Shaik, Saleem; Allen, Albert J..
The effects of the U.S. dollar exchange rate versus the Mexican peso are evaluated for four traded nonfarm-produced inputs (fertilizer, chemicals, farm machinery, and feed) in the U.S. Unit root tests suggest that the exchange rate and the four input price ratios support the presence of unit roots with a trend model but the presence unit roots can be rejected in the first difference model. This result is consistent with a fixed price/flex price conceptual framework, with industrial prices more likely to be unresponsive to the exchange rate than farm commodity prices.

Market Structure Conduct Performance (SCP) Hypothesis Revisited using Stochastic Frontier Efficiency Analysis AgEcon
Edwards, Seanicaa; Allen, Albert J.; Shaik, Saleem.
Use of efficiency measures as a proxy for performance to test the market structure-conduct-performance (SCP) hypothesis is explored. Utilizing Battese and Coelli specification, we estimate stochastic frontier production function and SCP equations with output and efficiency measures as endogenous variables. An empirical application to U.S. trucking carries over the period 1994-2003 with emphasis on the agricultural commodity and refrigerated food products carriers is examined. Results reveal that the variables average haul, average load and market concentration significantly affected the efficiency of firms with 2-8 number of years within each firm.

Crop Revenue and Yield Insurance Demand: A Subjective Probability Approach AgEcon
Shaik, Saleem; Coble, Keith H.; Knight, Thomas O.; Baquet, Alan E.; Patrick, George F..
A multinomial logit is utilized to model the choice of whether to purchase yield or revenue insurance using subjectively elicited survey data. Our results indicate that the demand for crop insurance is inelastic (-0.40), consistent with most earlier yield elasticity estimates, but the elasticity for choices between yield and revenue insurance is found to be relatively more elastic (-0.88).
