  The core-periphery model with transport costs in differentiated agriculture
is extended to continuous space. A homogeneous stationary solution is unstable
but exhibits redispersion that it is stabilized by sufficiently low
manufacturing transport costs or sufficiently strong preference for
manufacturing variety. It is numerically observed that a solution starting from
around the unstable homogeneous solution eventually forms a spike-like
agglomeration. Moreover, the redispersion also appears in the sense that the
number of the spikes goes from decreasing to increasing as the manufacturing
transport costs decrease. It is also observed that lower agricultural transport
costs and stronger preference for agricultural variety promote agglomeration.
