Do development projects crowd-out private sector activities? Evidence from contract farming participation in Northern Ghana

Contract farming (CF) is attractive as a possible private sector-led strategy for improving market coordination and smallholder farmers’ welfare. At the same time, governmental and non-governmental development projects aimed at improving farmers’ welfare continue to be organized. It is not uncommon for CF activities and development projects to take place in the same communities. Yet so far there is no evidence on how development projects affect CF activities. We examine factors affecting entry in and exit from different maize CF schemes in Northern Ghana, and focus specifically on the role of development projects. We find that the presence of agricultural development projects in the community is associated with lower scheme entry, but this not the case for non-agricultural projects. CF exit is more strongly associated with maize projects, but not significantly with non-maize or non-agricultural projects. Thus, our findings do not support concerns of a general moral hazard problem arising from the presence of any development project, but indicate possible negative associations of more closely related agricultural or maize projects with maize CF participation.

Modeling Overnight Recreation Trip Choice: Application of a Repeated Nested Multinomial Logit Model

In this paper we apply the repeated nested multinomial logit model, a version of a random utility model (RUM), to estimate the choice of an overnight versus single day recreation trip, along with the other usual choice of which of the sites to visit, and less typically, the choice of whether to participate (in our application – to fish) at all. We also find statistically significant income effects in the empirical results. The application is to Atlantic Salmon fishing and the data set is for Maine resident angler's fishing trips to rivers in Maine and Canada.

日本渔业的生产经营与课题

日本地理环境优越,渔业生产经营。但是在经历了经济高速发展年代的掠夺式捕捞之后,水产资源减少,渔业生产经营下滑,环保规制加强。在此背景下,日本调整渔业生产经营结构,引进总容许渔获量制度,提倡营造诱渔林,改善渔村环境,收到初步成效;同时,也面临渔业后继乏人、生产效率和效益低迷等问题。其经验教训值得我国借鉴,其进口需求扩大不失为我扩大对日水产品出口的良机。
