A situation is analysed in which two countries negotiate the financing of the incremental costs which accrue if one of them switches from a non-sustainable onto a sustainable development path. The other country's incentive to pay arises as it benefits from the developing country's environmental...

We present a two-step approach of assessing whether major donors of foreign aid have met recent demands for less proliferated and better coordinated aid efforts. First, we calculate Theil indices revealing the concentration of each donor's aid on recipient countries and specific aid sectors....

We examine the interaction between foreign aid and binding borrowing constraint for a recipient country. We also analyze how these two instruments affect economic growth via non-linear relationships. First of all, we develop a two-country, two-period trade-theoretic model to develop testable...

The typical identification strategy in aid effectiveness studies assumes donor motives do not influence the impact of aid on growth. We call this homogeneity assumption into question, first constructing a model in which donor motives matter and then testing the assumption empirically

A key issue in development economics is the explanation of core-periphery patterns around the world. Combining this issue with that of analyzing unilateral transfers (e.g. foreign aid) points in the direction of the use of New Economic Geography (NEG) models which, so far, has not been done...

In the past few years, the volumes of Russia's aid to foreign states remained high. Also, substantial growth was observed in the share of the bilateral development aid (when the aid is channeled directly to the recipient) as compared to the multilateral aid (when it is provided through...
