We study a model of equilibrium sovereign default in which the government issues cocos (contingent convertible bonds) that stipulate a suspension of debt payments when the government faces liquidity shocks in the form of an increase of the bondholders' risk aversion. We find that in spite of...

Turnover (sales) is frequently used in developing countries as a presumptive income tax base, to economize on the costs of tax administration and taxpayer compliance. We construct a simple model where a size threshold separates firms paying turnover tax from those paying profit tax (regular...

The paper advocates leveraging anti-money laundering (AML) measures to enhance tax compliance, tackle tax crimes, and, in turn, help mobilize domestic revenues. While AML measures have already been deployed to improve tax compliance, including during the European debt crisis, the benefits that...

This paper estimates bond-by-bond "haircuts"-realized investor losses-in recent debt restructurings in Russia, Ukraine, Pakistan, Ecuador, Argentina, and Uruguay. We consider both external and domestic retructurings. Haircuts are computed as the percentage difference between the present values...

In the context of the current tax policy debate in the United States, this paper reviews and discusses some of the main recurrent themes, as well as some of the most important tax reform proposals put forward over the past two decades. It finds that although there seems to be widespread...

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...

Mobilizing more revenue is a priority for sub-Saharan African (SSA) countries. Countries have to finance their development agendas, and weak revenue mobilization is the root cause of fiscal imbalances in several countries. This paper reviews the experience of low-income SSA countries in...

Many developing economies are heavily exposed to commodity markets, leaving them vulnerable to the vagaries of international commodity prices. This paper examines the use of commodity options-including plain vanilla, risk reversal, and barrier options-to hedge such risk. It then proposes the use...

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...
