Agricultural Productivity and Environmental Impacts: The Role of Non-parametric Analysis
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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).

Dynamic Relationships Between Farm Real Estate Values and Federal Farm Program Payments
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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...

Sensitivity of Rural Housing Values to Aggregate Economic Policy
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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,...

Exchange Rates Impacts on Agricultural Inputs Prices using VAR
Provedor de dados: 31
Autores: 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.

Issues on energy have recently dominated the economic decisions of several states across the U.S. economy and states in the southeastern region of U.S. are no exception. Almost all the states in the southeast import virtually all of their fuel resources from the Gulf Coast representing an annual financial diversion of several billions of dollars some of which could be used to develop domestic, alternative energy resources. The focus of this study was to determine the potential substitution between renewable energy and conventional energy forms in the southeast of U.S. We developed a system of factor share equations using translog cost function. The system of equations was estimated using a pooled iterative Non-linear Seemingly Unrelated Regression (SUR)...

Provedor de dados: 31
Autores: Shaik,   Saleem; Atwood,   Joseph A.; Helmers,   Glenn A.
The proportions of land values generated by farm program payments and farm returns are examined using an extended income capitalization model. The extended income capitalization model addresses the identification issue introduced by the counter-cyclical nature of farm program payments and farm returns. Procedures are presented that allow the estimation of agriculture land value shares without requiring explicit knowledge or assumptions with respect to the net land rental shares of farm returns or farm program payments. Results from the panel recursive or triangular-structure simultaneous equation model applied to 48 states in the U.S. for the period 1938 to 2006 indicate on average 41-45.6 percent and 54.4-59 percent of the agricultural land values can be...

Results from the analyses indicate that repealing the 7 percent grocery tax would produce modest gains in grocery sales but major increases in the purchases of other goods and services. Revenues from the sale of additional groceries would be exempt from taxes, thus producing only employment and labor income. With the state loosing almost $202 million in tax revenues, it is not clear if the gains in employment would be enough to offset the revenue losses.

Accounting for (In)Efficiency in the Estimation of Time-Varying Returns to Scale
Provedor de dados: 31
Autores: Shaik,   Saleem.
This paper has a two-fold contribution. First, it examines the importance of accounting for (in)efficiency in the estimation of primal production function on the input elasticities, technical change, and calculation of returns to scale. Second, it applies a variant of the rolling regression technique to identify time-varying input elasticities, technical change, and return to scale. Empirical application to the Asian agriculture sector using Food and Agricultural Organization data from 1961-2005 indicates returns to scale are underestimated by the traditional pooled and panel models. Further, the time-varying estimates of input elasticities, technical change, and returns to scale indicate variations with each additional year of information.

Relative proportion of agricultural land values generated by farm program payments, farm returns, and non-farm activity in the mountain region and the U.S are estimated for the period 1939 to 2005.  Results suggest the contribution of farm program payments to agricultural land values in the mountain region and the U.S. is quite similar and robust across the four alternative panel estimators for the period, 1939-2005.  The contribution of the farm returns to value of land is lower in the mountain region compared to the U.S.  The contribution of non-farm activity to the land values is higher for the U.S. compared to the mountain region.  The relationship between farm program payments and farm returns are positive in mountain region and negative for U.S.

Provedor de dados: 31
Autores: Helmers,   Glenn A.; Shaik,   Saleem; Atwood,   Joseph A.
Using a non-parametric linear programming approach, our contribution is (1) to examine if efficiency gains in hog production are realized due to vertical integration and (2) to demonstrate the efficiency gains that are realized are a product of economies of scope and scale.  The model uses U.S. hog sector data for the period, 1982-1997.  Results indicate efficiency gains are realized due to vertical integration and can be explained by scope and scale efficiency gains.  The t-test at the 5% level of significance indicates the mean overall efficiency gains; scope efficiency gains and scale efficiency gains are significantly different from one.

AGGREGATION ISSUES IN THE ESTIMATION OF MALMQUIST PRODUCTIVITY MEASURES
Provedor de dados: 31
Autores: Shaik,   Saleem.
The paper contributes by demonstrating the sensitivity of nonparametric programming productivity measures to the choice of model –time series versus panel models of Malmquist productivity, and to various levels of commodity aggregation compared to the traditional Tornqvist-Theil index approach employing U.S. state-level data from 1960-96.  To illustrate the sensitive of nonparametric programming productivity measures, we compare the implicit shadow shares recovered from the dual values of the Malmquist productivity and total factor productivity methods to the observed shares of the Tornqvist-Theil index for U.S level data from 1948-1994.

Autores: Shaik,   Saleem; Allen,   Albert J.; Edwards,   Seanicaa; Harris,   James.
Stochastic frontier analysis, which is used to estimate the technical efficiency, is extended to examine the market structure, conduct and performance hypothesis for the U.S. trucking industry. The technical efficiency measure takes into account not only the relationship between inputs used in the production of output but also simultaneously examine the importance of market structure conduct factors on the performance of the firm. An empirical application to U.S. trucking carriers over the period 1994-2003 is examined. Results reveal that the variables average haul, average load, debt-to-equity and market concentration significantly affected technical efficiency. Capital, fixed and variable input variables were significant in the production function...

OPTIONAL UNIT POLICY IN CROP INSURANCE
Provedor de dados: 31
Autores: Shaik,   Saleem; Atwood,   Joseph A.
Utilizing ordered logit we examine the presence of two kinds of asymmetric information-adverse selection (intertemporal variability) and moral hazard (interspatial and/or residual variability) as revealed by the choice of optional units in Federal crop insurance utilizing Risk Management Agency's 1996-2000 cotton yield and loss data files.  Further, a tobit model is estimated to examine the factors explaining the loss cost ratio from Risk Management Agency perspective.  Potential costs of adverse selection and/or moral hazard in optional unit provision are estimated to be as high as $180 million in US cotton over the 1996-2000 period.  Keywords:  Adverse Selection, Moral Hazard, Optional Unit Policy, Crop Insurance, U.S. Cotton, Logit and Tobit models.

The Impact of Trade Openness on Technical Efficiency in U.S. Agriculture
Provedor de dados: 31
Autores: Miljkovic,   Dragan; Shaik,   Saleem.
This study addresses the impact of trade openness on technical efficiency in the U.S. agricultural sector. The results indicate that trade protectionism illustrated with a decrease in the share of agricultural imports in agricultural GDP led to an increase in technical efficiency. A change in the share of agricultural exports in agricultural GDP had no impact on technical efficiency. These results are partially consistent with the premise of the new trade theory, but also seem to be driven by the intricacies of the agricultural sector and agricultural policy in the United States and internationally.

Time-Varying Estimation of Crop Insurance Program in Altering North Dakota Farm Economic Structure
Provedor de dados: 31
Autores: Coleman,   Jane A.; Shaik,   Saleem.
This study examines how federal farm policies, specifically crop insurance, have affected the farm economic structure of North Dakota’s agriculture sector. The system of derived input demand equations is estimated to quantify the changes in North Dakota farmers’ input use when they purchase crop insurance. Further, the cumulative rolling regression technique is applied to capture the varying effects of the farm policies over time. Empirical results from the system of input demand functions indicate that there is no moral hazard since North Dakota farmers will increase fertilizer and pesticide use in the presence of crop insurance. Results also indicate that farmers in this state will not increase the use of land.

Autores: Shaik,   Saleem; Helmers,   Glenn A.; Langemeier,   Michael R.
The implications of treating environmental pollution as an undesirable output (weak disposability) as well as a normal input (strong disposability) on the direct and indirect shadow price and cost estimates of nitrogen pollution abatement is analyzed using Nebraska agriculture sector data.  The shadow price of nitrogen pollution abatement treated as an undesirable output represents the reduced revenue from reducing nitrogen pollution.  In contrast, the shadow price of nitrogen pollution abatement treated as an input reflects the increased cost of reducing nitrogen pollution.  For the 1936-97 period, the estimated shadow price and cost of nitrogen pollution abatement for Nebraska ranges from $0.91 to $2.21 per pound and from $300 to $729 million respectively.

Willingness to Pay for a Potential Insurance Policy: Case Study of Trout Aquaculture
Provedor de dados: 31
Autores: Shaik,   Saleem; Coble,   Keith H.; Hudson,   Darren; Miller,   James C.; Hanson,   Terrill R.; Sempier,   Stephen H.
Using trout producer survey data and the contingent valuation method, we estimate willing-ness to pay for a potential insurance policy. The survey was conducted in 2005 across the United States; 268 producers completed the survey instrument, resulting in a response rate of 81 percent. Design of the contingent valuation method takes into account two coverage levels and four premium rates. Using standard willingness-to-pay techniques, we assess the premium rate that producers with varying practices and regions are willing to pay for two different cov-erage levels of insurance. In general, trout producers appear willing to pay premium rates of 2 to 11 percent for these coverage levels.

This study was conducted to analyze the direct and indirect effects of ethanol policy on livestock production.  Results of the theoretical model indicate the possibility of ethanol policy indirectly affecting livestock production.  Econometric results show a possibility of ethanol policy indirectly impacting cattle production through the RFS’s influence on corn quantity.  Policy makers’ intentions with ethanol policy likely were to increase ethanol consumption rather than to directly affect cattle production.  However, results of the reduced form equation indicate that the RFS increased the cattle quantity, which represents a direct outcome of ethanol policy on cattle production.  Policy makers can utilize the information provided in this study to...

It focuses on the own and cross relationship between the expenditure share and price, income changes.  An Almost Ideal Demand System (AIDs) model and two alternative specifications are used to estimate a system of expenditure share equations for shrimp, beef, pork, and chicken.  Empirical results indicated that some insignificant slope coefficients and inappropriate signs of them did not comply with microeconomic theory. This could be caused by heteroscedasticity, autocorrelation, a limitation in the data used, or shrimp is a commodity that is quite different.

Farm transfer or succession by the “next generation” holds a place of central importance in the determination of industry structure and total number of farmers and has profound implications for farm families. The family farm sector relies heavily on intergenerational succession. Succession and retirement are linked and reflective of the life cycles of the farm household and the farm business. A large farm-level data set and a logistic regression model were used to examine the determinants of farm succession decisions in the United States, with special emphasis given to the treatment of endogenous wealth and farm size variables. Results point to the importance of farmer’s age, educational attainment of farm operators, off-farm work by the operator or...

This study addresses the impact of trade openness on technical efficiency in the U.S. agricultural sector.  The results indicate that trade protectionism illustrated with a decrease in the share of agricultural imports in agricultural GDP led to an increase in technical efficiency. A change in the share of agricultural exports in agricultural GDP had no impact on technical efficiency.  These results are partially consistent with the premise of the new trade theory, but also seem to be driven by the intricacies of the agricultural sector and agricultural policy in the US and internationally.

Does Accounting for Inefficiency Affect the Time-Varying Short and Long-Run Returns to Scale?
Provedor de dados: 31
Autores: Shaik,   Saleem.
The returns to scale for nineteen South Asian countries are estimated using window and cumulative rolling stochastic frontier regression analysis. The stochastic frontier analysis accounts for technical inefficiency of Hicks non-neutral technology production function in the estimation of the returns to scale. The window rolling regression and cumulative rolling regression allows the estimation of short and long run time-varying returns to scale, respectively. Empirical application to Asian agriculture sector using Food and Agricultural Organization data from 1961-2008 indicates returns to scale are under (over) estimated by the traditional panel models in the short (long) run time-varying estimation. The time-varying estimates of returns to scale indicate...
