Legal Status and U.S. Farm Wages

Using National Agricultural Workers Survey data, we estimate U.S. farm worker wage differentials by legal status. In order to adequately correct sample selection bias, we develop a Heckman-type two-stage method with an ordered probit model in the first stage and a wage equation model in the second stage.Farm Management,

Labor Cost and Technology Adoption: Least Squares Monte Carlo Method for the Case of Sugarcane Mechanization in Florida

The prospect of immigration reform has renewed farmers’ concerns of serious labor shortages and cost increases, which may urge highly labor-intensive specialty crop farmers to switch to less-labor-intensive technology. The large-scale mechanization of the Florida sugarcane harvest during the 1970s/80s serves as an historical example of how technologies evolved due to changes in local labor market conditions. We analyze the dynamic decision-making process of sugarcane farmers in the relevant period using net present value (NPV) approach and real options approach (ROA) with least squares Monte Carlo (LSMC).Crop Production/Industries, Labor and Human Capital, Research and Development/Tech Change/Emerging Technologies,

Implications of Proposed Immigration Reform for the U.S. Farm Labor Market

Specialty crop agriculture may be affected by immigration reform given that most farm workers are foreign-born and unauthorized for U.S. employment. Controlling for selection on legal status and job type according to skill level, this research examines the wage effects for workers with different characteristics in the U.S. and South.Labor and Human Capital,

Farm Employment Transitions: A Markov Chain Analysis with Self-Selectivity

A stationary, first-order Markov chain model with selection bias correction for legal status is estimated by maxixmum likelihood methods using the National Agricultural Worker Survey data for 1989-2004 to evaluate the likelihood of workers staying in U.S. agriculture by legal status. Although the conditional steady state probability in US agriculture is highest for uanauthorized workers, there is little difference between legal statuses. Simulations of the estimated model indicate that a legal status change for unauthorized workers would result in only small changes in the steady state probability of being in US agriculture, particularly after 2001.Labor and Human Capital,

Labor Cost and Value of Citrus Operations with Alternative Technology: Enterprise DCF Approach

The prospect of immigration policy reform has renewed growers’ concerns of serious labor shortages and cost increases given that a large portion of the workforce is unauthorized for U.S. employment. This concern of labor shortages and cost increases is more serious for specialty crop agriculture which is highly labor intensive. Specialty crop growers may address the problem in various ways, but likely options include adoption of mechanical harvesting. In the current paper we study the citrus industry case and estimate the value for two operational modes (hand and mechanical harvesting) using the enterprise discounted cash flow (DCF) approach. Further we implement a simulation to forecast how the value for each operational mode would change with a change in cost scenario.Value, Enterprise DCF approach, Labor cost, Citrus operations, Mechanization, Agricultural Finance, Labor and Human Capital, Q14, J43,

PROPOSED IMMIGRATION POLICY REFORM & FARM LABOR MARKET OUTCOMES

The issue of legalization for unauthorized farm workers is examined in this paper. The analytical framework uses a treatment effects approach which casts legalization as a treatment under the assumption of heterogeneity. The results show an overall positive impact of legalization on farm worker wage outcomes and with the expected positive sorting on the gains from legal status.International Relations/Trade, Labor and Human Capital,

Harvest Cost and Value of Citrus Operations with Alternative Technology: Real Options Approach

The prospect of immigration policy reform has renewed growers’ concerns of serious labor shortages and cost increases. These concerns are more serious for specialty crop agriculture, not only because it is highly labor intensive, but also it requires labor in a very short period, particularly at harvest time. Two representative approaches of the investment valuation have been applied to the case of harvesting mechanization for the model citrus grower in Florida. Specifically, we applied the NPV approach and the real options approach (ROA) to processed-market Hamlin orange operations in Southwest Florida.Real options, NPV, mechanization, immigration policy, harvest cost, citrus operations, Agribusiness, Agricultural Finance, Farm Management, Labor and Human Capital, Risk and Uncertainty, Q14 – Agricultural Finance, J43 – Agricultural Labor Markets,

Labor Cost and Technology Adoption: Real Options Approach for the Case of Sugarcane Mechanization in Florida

Scalable Noise Estimation with Random Unitary Operators

We describe a scalable stochastic method for the experimental measurement of generalized fidelities characterizing the accuracy of the implementation of a coherent quantum transformation. The method is based on the motion reversal of random unitary operators. In the simplest case our method enables direct estimation of the average gate fidelity. The more general fidelities are characterized by a universal exponential rate of fidelity loss. In all cases the measurable fidelity decrease is directly related to the strength of the noise affecting the implementation -- quantified by the trace of the superoperator describing the non--unitary dynamics. While the scalability of our stochastic protocol makes it most relevant in large Hilbert spaces (when quantum process tomography is infeasible), our method should be immediately useful for evaluating the degree of control that is achievable in any prototype quantum processing device. By varying over different experimental arrangements and error-correction strategies additional information about the noise can be determined.Comment: 8 pages; v2: published version (typos corrected; reference added

The U.S. Farm Labor Market Post-IRCA: An Assessment of Employment Patterns, Farm Worker Earnings and Legal Status

Immigration reform may significantly impact the specialty crops sector since more than half of the workforce is foreign-born and undocumented. Based on data from the National Agricultural Workers Survey, the trends pertaining to workers' legal status, employment and wage rates in the U.S. and Florida farm labor markets are examined.Immigration reform, legal status, specialty crops, employment, wage rates., Labor and Human Capital, J430,
