| Entrepreneurs innovate their individual business organizations not only to deal with production and price risks, but also to cope with the risk of sanctions or penalties imposed by society's laws and regulations. More specifically, labor-intensive agricultural firms, faced with potentially large fines for violation of immigration and labor laws, increasingly modify the organization of their firms by shifting the management of routine seasonal labor jobs to independent farm labor contractors. The use of labor contracting is further intensified because of the effectiveness of labor contractors in the recruitment of illegal aliens. |

| 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. |

| We have proposed and estimated a Heckman-type two stage model with legal status of farm workers using an ordered probit model in the first stage and a duration model in the second stage. Using the National Agricultural Workers Survey, self-reported legal status categories are: unauthorized, authorized, permanent resident, or citizen. The duration model is estimated conditionally upon the worker's legal status to address selectivity bias. The duration estimation has significant coefficients on the selection bias correction term for all legal status equations except for that of citizen workers. The most important finding from our estimation is that unauthorized workers do not necessarily have shorter farm job durations than legal workers. First, the... |

| A cost function approach of induced innovation is used to measure the biases in U.S. agricultural technology between 1948-1994. The results show significant labor-saving, capital-using technical change. Focusing on the impact of migration policy on labor-saving technology, a simulation of different rates of labor-saving technical change is conducted. The simulation shows decreases in elasticity of labor demand and demand quantity, and an increase in wage rate as technology becomes more labor-saving. |

| A multi-output cost function approach to induced innovation is adopted to analyze the impact of socioeconomic variables and institutional factors on technological change in agriculture. Focusing on the impact of immigration policy and farm mechanization, the study includes variables such as H-2A or guest workers, deportable Mexicans working in agriculture representing the percentage of unauthorized workers, the public and private research expenditures on farm mechanization and other research on agricultural technology. We found that over the 1971-1995 period, the technology was biased toward labor-saving technology, but was capital-neutral. The number of unauthorized workers had no significant effect on cost shares; the number of H-2A workers had a... |
