My research and teaching interests can be broadly classified as micro-econometrics. Much of my research focuses on farm decisions, from production to off-farm employment. Previous research focused on the farm family labor decisions, productive and allocative efficiency for dairy and cranberries in Massachusetts and for Bulgarian dairy production and CSA costs, returns and marketing. More recently I analyzed the impacts of the Northeast Dairy Compact on retail milk prices and the costs of production for fluid milk in the northeast and asymmetries in farm to retail price transmission. In addition, my tenure as graduate program director prompted an investigation into the value of graduate education in the field of resource economics and the effects of technology on introductory statistics education.

I am currently analyzing the costs and returns of three different production methods for nursery crops in New England. With support from the USDA National Institute of Food and Agriculture, we have established 3 field trials in Massachusetts and New Hampshire to determine whether alternative soil saving technologies can compete with the traditional balled and burlapped production method. The grant continues through 2012.

I am also interested in water quality in New England streams and rivers, as well as other selected states, and the implications for specific forms of outdoor recreation. I am developing this research in my spare time focusing more specifically on aquatic entomology, salmonid populations, their interdependence and the effects on an individual's utility (namely, mine).

Recent Activities

My teaching coincides with my research interests. I teach the first course in econometric theory in our graduate program. The course includes theory of estimation of the single equation model. We then consider the effects on our estimators when classical assumptions are lost. We finish with a quick look at limited dependent variable models. At the undergraduate level, I teach introductory statistics and introductory econometrics. In econometrics, the application of econometric methods for decision-making and policy analysis is emphasized with primary emphasis on microeconomic models of the firm and consumer.

I have been active in the Northeast Agricultural and Resource Economics Association serving as President, a member of the Board of Directors and several other committees. I have provided research that has been used to determine agricultural land values in Massachusetts for taxation purposes and am currently a designee to the Farmland Valuation Advisory Commission.
