Digital connectivity, including through the modern cellular network technologies, is expected to play a key role for the Future of Work in sub-Saharan Africa (SSA). We estimate the cost of introducing a full-scale 4G network by 2025 in SSA and an operable 5G network by 2040. We adapt the costing...

The treatment of license payments in the national accounts has become increasingly important in recent years; with mobile phone licenses being auctioned for substantial values in several countries. Because the text of the System of National Accounts 1993 does not provide specific guidance on...

Effective public investment requires governments to address the "recurrent cost problem" to ensure operations and maintenance (O&M) expenditures are sufficient to sustain the flow of productive public capital services to private factors of production. Building on the model of Buffie et al...

We create a network of bilateral correlations of changes in sovereign bond yields and individual bank equity price changes since 2000. We extract some stylized facts from this network of asset price correlations and document the clear differences in asset price correlations between safe havens...

We consider a moral hazard economy in banks and production to study how incentives for risk taking are affected by the quality of supervision. We show that low interest rates may generate excessive risk taking. Because of a pecuniary externality, the market equilibrium may not be optimal and...

The paper examines the joint impact of inflation targeting (IT) and fiscal rules (FR) on fiscal behavior and inflation in a broad panel of advanced and developing economies over the period 1990-2009. The main contribution of the paper is to show that, as suggested by the theoretical literature,...

The global financial crisis highlighted that the financial system can be most vulnerable when it seems most stable. This paper models non-linear dynamics in banking. Small shocks can lead from an equilibrium with few bank defaults straight to a full freeze. The mechanism is based on...

Does the distribution of income within a country become more equal as it grows richer? This paper uses plausibly exogenous variations in trade-weighted world income and international oil price shocks as instruments for within-country variations in countries' real GDP per capita to examine this...

Potential output estimation plays a crucial role in conducting fiscal policy based on structural balances. Difficulties in estimating potential output could lead to an erroneous policy stance with a consequent impact on growth. This paper analyzes historical data on revisions of actual and...
