What motivates farm couples to seek off-farm labour? A logit analysis of job transitions
利用挪威农户20年非平衡面板数据和Logit模型，分析农户夫妇从纯农业转向非农就业的决策因素，发现牲畜数量增加会降低非农参与概率，而农场规模扩大则相反。
Some labour market consequences of transitions in the agriculture sector are examined by combining 20-year unbalanced panel data from Norwegian farm households and logit modelling of transition probabilities. The multi-dimensionality of the problem follows from two decision makers having four possible choices in each period: the farm operator and spouse can be working fully on the farm or having supplementary outside occupation. Transitions are modelled by five logit models. The most flexible model has a high number of parameters. Overall, the results indicate that transitions have mainly been directed towards the state where both partners work off the farm. An increasing livestock reduces the probability of moving to states with substantial off-farm labour participation. Increasing farm size tends to have the opposite effect. Recent on-farm investments come out with ambiguous effects. Having children seems to motivate operators to withdraw from off-farm labour and spouses to stay in or enter off-farm employment.
