Abstract

In the constructed-capital model, the steady state is derived under the assumption that each individual behaves optimally. Contrasting to this decentralized approach, in this paper we derive the first-best outcome a central planner would choose. The results show that agglomeration is socially not optimal, irrespective of the level of trade barriers. Furthermore, the differences in the explicit solutions of both approaches are highlighted.

Notes

  1. For other contributions considering public expenditures in the New Economic Geography literature we refer to Trionfetti (1997, 2001), Martin and Rogers (1995) and Brakman et al. (2008). Some empirical evidence can be found in Brülhart and Trionfetti (2004).

  2. Therefore capital is a production factor for the manufacturing sector as it determines the number of different machines (equivalent to the number of different products). The number of product varieties depends on the capital stock. However, the amount of each product variety does not depend on the capital.

  3. Trade costs are assumed to be equal for both regions. However, the model allows to generalize this assumption straightforwardly.

  4. A stable population is characterized by constant mortality and fertility rates over time. This implies that the demographic structure does not change.

  5. Note that this implies that the social planner treats each individual in the same way. Therefore a region with a higher population has a higher weight in the social welfare function.

  6. Due to concavity of the Hamiltonian with respect to the states also second-order conditions are fulfilled. As long as the states are positive that concavity is strict.

  7. The time points when a state touches, enters or exits the constraint.

  8. \(\tau ^{+}\) and \(\tau ^{-}\) denote the limit from the right and the left respectively.

  9. A complete list of all possible parameter ranges is provided in Appendix A in Wrzaczek (2010).

  10. For each parameter we have chosen very small steps within the possible parameter interval.

  11. Note that the difference in labor efficiency is due to differences in the demographic structure of the population. The productivity of individuals depends e.g. on age and on their health. However, the demographic structure is not modeled explicitely in our model and assumed as exogenous.

  12. Note that \(\dot{\lambda }^{H} =0\) if \(\dot{K}^{H} =0\), which is fulfilled.

  13. \(L^{H}=L^{F}=1,\,N^{H}=N^{F}=1,\,\rho =0.015,\,\delta =0.05,\,\xi =0.3,\,\sigma =2,\,\varGamma =2,\,\alpha =1,\,\beta =1,\,\varphi =2\)

  14. For clarification once again: \(\hat{K}^{d}\) denotes the equilibrium capital of the decentralized Baldwin model in the symmetric equilibrium, \(\hat{K}^{H}\) and \(\hat{K}^{F}\) denote the equilibrium capital of the centralized model of the home and the foreign country respectively.

  15. Note that this argument is not valid in Baldwin (1999), as it assumes an arbitrary number (e.g. one) of individuals who live forever. For a decentralized model with finitely living individuals we refer to the more sophisticated model proposed in Grafeneder-Weissteiner and Prettner (2008).
