This paper (i) traces the historical origins of foreign aid, (ii) investigates tren­ds in the volume, composition, allocation and quality of aid flows, and (iii) reviews the empirical literature on aid allocation. The paper concludes that, historically, aid has served a multitude of objectives....

This paper traces the origins of World Bank indicators of debt distress and their employment as HIPC sustainability targets. These targets are interpreted as ‘switching values’, below which countries are (on average) expected to avoid debt service problems, but as such, they do not take into...

This paper traces the origins of HIPC debt sustainability targets. These targets are interpreted as ‘switching values’, below which countries are expected to avoid debt service problems, but as such, they do not take into account that countries encounter debt problems for a variety of...

In this paper we consider solutions which select from the core. For games with side payments with at least four players, it is well-known that no core-selection satifies monotonicity for all coalitions; for the particular class of core-selections found by maximizing a social welfare function...

In the minimum cost spanning tree model we consider decentralized pricing rules, i.e. rules that cover at least the efficient cost while the price charged to each user only depends upon his own connection costs. We define a canonical pricing rule and provide two axiomatic characterizations....

This paper is a survey of existing estimation techniques for stationary and ergodic diffusion processes observed at discrete points in time. The reader is introduced to the following techniques: (i) estimating functions with special emphasis on martingale estimating functions and so-called...

This paper develops a model of simple 'reputation systems' that monitor and publish information about the behavior of sellers in a market with search frictions and asymmetric information. The reputations created by these systems influence the equilibrium search patterns of buyers and thus...

In this article we show that technological parameter estimates obtained by estimating a cost function that is derivable as the dual of a production function can be biased and inconsistent if the stochastic structure of the model arises from certain types of behavioural assumptions made about...
