As a means to reduce delays in public works implementation, a number of Brazilian states have recently reformed their procurement rules allowing contractor price proposals to be assessed before the technical evaluation of submitted bids is undertaken (in a procedure known as inversao das fases)....

Is generalized debt relief an effective development strategy, or should assistance be tailored to countries' characteristics? To answer this question, the authors build a simple model in which recipient governments reveal their creditworthiness if donors offer them to choose between aid and debt...

Should donors who are interested in the effectiveness of developmental programs rely on conditional budget support or on project aid? To answer this question, we present a model in which only a subset of the developmental expenditures can be subject to conditionality. We show that budget support...

In this paper, we examine how the presence of country insurance schemes affects policymakers' incentives to undertake reforms. Such schemes (especially when made contingent on negative external shocks) are more likely to foster than to delay reform in crisis-prone volatile economies. The...

Under what conditions should grants be preferred to loans? To answer this question, we present a simple model a la Krugman (1988) and show that, for any given level of developmental assistance, the optimal degree of loan concessionality is positively associated with economic growth if countries...

In an economy a la Diamond and Dybvig (1983), we present an example in which foreign lenders find it profitable to invest in an emerging market if, and only if, the emerging market government imposes taxes on short-term capital inflows. This implies that capital controls that are effective in...

In this paper, we show that a central bank, by announcing and committing ex-ante to a bailout policy that is contingent on the realization of certain states of nature (for instance on the occurrence of an adverse macroeconomic shock), creates a risk-reducing quot;value effectquot; that more than...

International financial institutions (IFIs) generally enjoy preferred creditors treatment (PCT). Although PCT rarely appears in legal contracts, when sovereigns restructure bilateral or commercial debts they normally pay IFIs in full. This paper presents a model where a creditor, such as an IFI,...
