Abstract
Hog pseudorabies (Aujeszky's disease) can incur serious losses for farm owners and even the entire hog industry by causing infertility, abortion, and stillbirth among sows, as well as diarrhoea, respiratory failure, and death among piglets. Pseudorabies virus could be prevented, controlled, and eliminated by clean-up at both farm and regional levels through a strict procedure of vaccination, quarantine, diagnosis, elimination of positive animals, and healthy animals nurturing. Using data from 63 large-scale hog farms from nine provinces (municipalities, autonomous regions) of China, we evaluated the economic consequences of hog pseudorabies clean-up in China's hog farms based on a partial budgeting method. By comparing large-scale hog farms that have performed pseudorabies clean-up with similar farms that have not, we analysed how clean-up affected farm profit and whether there existed sufficient economic incentives for farm owners to adopt pseudorabies control measures. Further, we examined how the economic consequences varied with factors such as clean-up history and farm size. The findings showed that, on average, clean-up adopters outperformed non-adopters by 8.02 million yuan per farm per year within the four years post clean-up adoption. Also, we found that the net profit changes attributable to pseudorabies clean-up increased over time and with farm size. Although we cannot extrapolate to all Chinese hog farms, these findings suggest that the earlier a hog farm adopted pseudorabies clean-up, the larger the economic benefits would be, especially for large-scale farms.

Abstract
One of the main strategies to control the spread of infectious animal diseases is the implementation of movement restrictions. This paper shows a loss in efficiency of the movement restriction policy (MRP) when behavioral responses of farmers are taken into account. Incorporating the strategic behavior of farmers in an epidemiologic model reveals that the MRP can trigger premature animal sales by farms at high risk of becoming infected that significantly reduce the efficacy of the policy. The results are validated in a parameterized network via Monte Carlo simulations and measures to mitigate the loss of efficiency of the MRP are discussed. Financial aid to farmers can be justified by public health concerns, not only for equity. This paper contributes to developing an interdisciplinary analytical framework regarding the expansion of infectious diseases combining economic and epidemiologic dimensions.
