摘要：This paper uses a two-equation model, panel data from African countries during the 1992-1996 period and a dynamic panel estimator to investigate cost shifting in international telephone calls between these African countries and the US. Using call minutes as the dependent variable, we find that callers in African countries engage in cost shifting while their US counterparts do not. We also find that while US callers reciprocate call minutes from African countries to the US, callers in Africa do...

摘要：Trade liberalisation in developing countries over the last 20 years has often been implemented with the expectation of growth being stimulated; yet the evidence on its growth enhancing effects is mixed. This paper argues that problems with mis-specification and the diversity of liberalisation indices used are in part responsible for the inconclusiveness. Using a dynamic panel framework and three different indicators of liberalisation, the paper finds that liberalisation does appear to impact u...

摘要：If migrants return to their origin countries, two questions arise which are of immediate economic interest for both immigration and emigration country: what determines their optimal migration duration, and what are the activities migrants choose after a return. Little research has been devoted to these two issues. This paper utilises a unique survey data set which records activities of returned migrants. We first illustrate the activities of immigrants after returning. We show that more than h...

摘要：This paper investigates the impact of the heterogeneity of the labor force on the spatial distribution of activities. This goal is achieved by applying the tools of discrete choice theory to an economic geography model. We show that taste heterogeneity acts as a strong dispersion force. We also show that the relationship between the spatial distribution of the industry (the wage differential) and trade costs is smooth and bell-shaped. Finally, while Rawlsian equity leads to the dispersion of i...

摘要：We examine the impact of financial liberalization on fixed investment in Mexico using establishment-level data from the manufacturing sector. In addition to analyzing changes in cash-flow sensitivities, an innovative approach explores the role of real estate as collateral and addresses a potential censoring problem. The results suggest that financial constraints were eased for the smallest firms, but not for larger ones. However, the importance of possessing real estate increased, given banks'...

摘要：A new and very simple mechanism to explain why natural resource abundance may lower income and welfare is developed. In a model with rent seeking, a greater amount of natural resources increases the number of entrepreneurs engaged in rent seeking and reduces the number of entrepreneurs running productive firms. With a demand externality, it is shown that the drop in income as a result of this is higher than the increase in income from the natural resource. More natural resources thus lead to l...

摘要：An unstable macroeconomic environment is often regarded as detrimental to economic growth. Among the sources contributing to such instability, much of the blame has been assigned to political issues. This paper empirically tests for a causal and negative long-run relation between political instability and economic growth but finds no evidence of such a relationship. Sensitivity analysis indicates that there is a contemporaneous negative relationship but also that, in the long run and ignoring ...

摘要：We examine the interaction between credit markets, trade sanctions and the incidence of child labour in a two-good, two-period model with unequally wealthy households. Both poverty and poor education quality, inter alia, are important determinants of child labour. The incidence of child labour decreases as we move from the case of borrowing constraints to the case in which poor households can borrow freely from rich ones and then to the case of perfect international credit markets. Trade sanct...

摘要：This paper presents a model of industrialization through rural-urban interdependence. It shows how an economy with a low cost share of industrial inputs in agricultural production and a low expenditure share of manufactured goods, together with a limited variety of industrial inputs, can be caught in a low development trap. By escaping from the trap the economy moves toward more roundabout methods of agricultural production, mass consumption of manufactured goods, and urbanization. The transit...

摘要：We model separation of powers as an instrument against corruption, more specifically as a way to decrease the costs of collusion-proofness. Then, we show that the value of this institutional design is higher in developing countries. Unfortunately, the same reasons which are behind this higher value also increase the implementation cost of this institution. (C) 2001 Elsevier Science B.V. All rights reserved.
