While a considerable body of literature has developed in recent years around the drivers and consequences of rural out-migration in sub-Saharan Africa, relatively little work has been done to understand the impacts of migration into rural areas. We use nationally representative household survey data from Zambia to explore the relationship between rural in-migration and agricultural productivity outcomes in receiving communities. We document high levels of rural in-migration throughout Zambia—12% of rural household heads having moved from elsewhere within the previous 10 years—with two-thirds of rural in-migrants originating from other rural areas. Migrants are, on average, better endowed with capital resources than their nonmigrant neighbors and are more engaged with input and output markets. After controlling for other factors, we find that higher rates of rural in-migration are associated with greater agricultural productivity outcomes in receiving communities. These positive associations are particularly pronounced in more remote rural areas, and where in-migration originates from other rural areas. Taken together, our results suggest that rural in-migrants play an important role in the rural transformation processes underway in Zambia. 相似文献

In this study, an integrated model of return seasonality is developed and the hypothesis that seasonality is associated with changes in relative trading volume is examined. Return regularities associated with the turn of the month, the week of the month, and holiday closings are documented. Beyond these effects, neither the turn of the year nor the January effect is significant for large firms. Relative volume is shown to display calendar regularities similar to those in returns, and tests indicate a causal relationship flowing from volume to returns. 相似文献

Intra-Industry Trade — An In-Depth Study of Swedish Liquid Pump Trade. - The issue of intra-industry trade is here investigated through an in-depth case study of Swedish trade in pumps. A questionnaire was made in order to give detailed information about the trade flows. The survey indicates that the share of “true” IIT in Sweden's centrifugal pump trade in 1990 was about 10 percent. This part of the apparent IIT could not be attributed to “categorical aggregation”. The survey revealed twelve different causes of IIT. A large share of IIT was due to re-exports (= vertical IIT). Behavioural and institutional factors were the main explanations of the non-re-exports IIT (= horizontal IIT). 相似文献
