This paper finds optimal fiscal rule parameter values and measures the effects of imposing fiscal rules using a default model calibrated to an economy that in the absence of a fiscal rule pays a significant sovereign default premium. The paper also studies the case in which the government...

We present a simple model of petroleum exploration and development that can be applied to study the performance of alternative tax systems and identify potential distortions. Although the model is a highly simplified, it incorporates many factors and some of the key tradeoffs that would...

This paper highlights the importance of the role of the domestic tax system in determining the economic consequences of an external debt overhang. A simple taxation scheme is specified and it is shown that a country can be on the “wrong side” of its debt Laffer curve only if it is on the...

The stance of fiscal policy in CEMAC and WAEMU is strongly influenced by fiscal effort in the previous period. This persistence underscores the risks of a procyclical fiscal policy stance, given these countries' high degree of dependence on primary commodities and exposure to terms of trade...

Do tax incentives for science and technology stimulate additional investment? We use detailed data on applications and acceptances for R&D tax incentives, a special survey, and for the first time, the science and technology module from the 2000-2002 Survey of Manufacturers database in Colombia...

Asset booms and sectoral changes can distort traditional estimates of structural fiscal revenue, and could lead to serious fiscal policy errors. This paper extends the estimation of structural revenues to take account of asset prices and sectoral changes, and applies this to the case of Ireland,...

The paper assesses, using seven structural models used heavily by policymaking institutions, the effectiveness of temporary fiscal stimulus. Models can, more easily than empirical studies, account for differences between fiscal instruments, for differences between structural characteristics of...

This paper shows that concerted debt reduction may be welfare-improving even when the investment disincentive effect of a debt overhang is not large enough to place the debtor country on the wrong side of the debt Laffer curve. Whether the appropriate relief scheme involves debt reduction or new...
