Does the Jack of All Trades Hold the Winning Hand? Comparing the Role of Specialized versus General Skills in the Returns to an Agricultural Degree
研究农业毕业生在农业和非农业部门工作的收入差异，发现专业化技能在农业部门有溢价但随时间减弱，通用技能在非农业部门回报更高，且高能力学生倾向于选择与课程匹配的行业。
Abstract This paper examines the roles of specialized versus general skills in explaining variation in the returns to an agriculture degree among graduates working both inside and outside the agricultural industry. The focus on returns by sector of employment is motivated by our finding that most agricultural graduates are employed in non‐agricultural jobs. In that study, a sample of alumni graduating from a large Midwestern public university between 1982 and 2006 shows that alumni with majors more specialized in agriculture earned a premium from working in the agriculture industry, but this advantage has diminished over time. Agricultural graduates with more general training earn more outside than inside agriculture. Higher‐ability graduates in more industry‐focused curricula tend to sort into the agricultural industry, while higher‐ability graduates in broader curricula tend to choose jobs outside of agriculture. All graduates are more likely to accept agricultural employment when the farm economy is strong, but agricultural graduates who enter agricultural jobs when the farm economy is weak suffer lifetime earnings reductions. These findings suggest that greater levels of specialization may limit a graduate's ability to adjust to changing economic circumstances. Agriculture degree programs could benefit from curriculum innovations that focus on developing more generalized skills.
