This paper develops a dynamic model of technology adoption featuring strategic complementarities: the benefits of usage increase with the number of adopters. We study the diffusion of new means of payments, where such complementarities are pervasive. We show that complementarities give rise to...

This paper puts sub-Saharan Africa's economic development into perspective. While much did not go as hoped for at independence, much of the region has been on a more promising development trajectory since the mid-1990s, as we illustrate using growth, poverty, and human development indicators. We...

Large-scale business subsidies tied to national industrial development promotion programmes are notoriously difficult to study and are often inseparable from the political economy of large government programmes. We use the Tunisian national firm registry panel database, data on treated firms,...

There is a debate in the literature on the appropriate methods and metrics for evaluating the economic impacts of tourism investments. Available analytical techniques include input-output modelling, computable general equilibrium modelling, cost benefit analysis, expenditure-based methods, and...

The literature on aid effectiveness has focused more on recipient policies than the determinants of aid allocation yet a consistent result is that political allies obtain more aid from donors than non-allies. This paper shows that aid allocated to political allies is ineffective for growth,...

This paper examines whether the federal structure of aid-receiving countries matters in explaining aid effectiveness. Following the decentralization theorem, the devolution of powers should increase aid effectiveness, since local decision-makers are better informed about local needs. At the same...

Controversy over the aggregate impact of foreign aid has focused on reduced form estimates of the aid-growth link. The causal chain, through which aid affects developmental outcomes including growth, has received much less attention. We address this gap by: (i) specifying a structural model of...

This paper confirms recent evidence of a positive impact of aid on growth and widens the scope of evaluation to a range of outcomes including proximate sources of growth (e.g., physical and human capital), indicators of social welfare (e.g., poverty and infant mortality), and measures of...

The aid-growth literature has been explored using a wide range of econometric methodologies. The evidence of the effectiveness of aid to promote economic growth is mixed, suggesting that the link between aid and growth is complex and may not be well identified by traditional methods. We take...
