Transaction costs and the collection of information: presale measurement on private timber sales

Measurement efforts to reduce the uncertainty concerning theattributes of heterogeneous goods may simply redistribute wealthand result in social waste. Individuals bearing the cost ofsuch distributional measurement have incentives to develop buyingand selling practices that limit such measurement. We examine,both theoretically and empirically, the determinants of thelevel of distributional measurement efforts in a competitiveauction framework. The empirical application, which uses a sampleof private timber sales, provides strong support for the implicationsof the theoretical model of presale measurement.

External aid: help or hindrance to export orientation in Africa?

The central proposition of this paper is that African countriesshould start thinking through undertaking an orderly transitionfrom the current high dependence on foreign aid for financingeconomic and social development. Aid dependency should be reducednot because the international development community believesit will eventually happen, but because such dependence on foreignaid could substantially impair Africa's export competitivenessand therefore derail the Continent export-oriented developmentstrategies. A combination of further debt relief, reforms ofthe current aid regime and enhanced policy environment shouldallow a managed transition to a mixed menu of official developmentassistance (ODA) and private capital flows. However, the attemptby Africa to increase its share of investments from internationalprivate capital markets should be firmly anchored to the basictenets of an export-based development strategy. To provide thebasis for these policy conclusions, I estimate the relationshipbetween ODA, real exchange rates (RER) and non-traditional exportsfor a panel of 62 developing countries, including 28 from Africa.Unsustainable ODA flows were shown to have caused substantialpartial RER overvaluation in many African and non-African countries.Moreover, exceptionally high aid-dependent African countrieshave either experienced, or are likely to experience, overallRER overvaluation. Conditional on absence of RER overvaluation- a proxy for good policy environment of relevance to exportperformance - a robust Laffer curve-type relationship existsbetween aid and non-traditional exports through the misalignmentof RER relative to its equilibrium. The Laffer curve relationshipjustifies a 'precise' concept of aid dependency, based on theextent to which excessive ODA flows exceeded the threshold beyondwhich more ODA actually hinders rather than helps export expansion.According to this concept, several African countries were characterisedas being 'aid dependent'.

Investment appraisal in the public sector

Recent developments, such as privatization and the private financeinitiative, have raised the issue of which assets should beowned by the public sector and whether assets have differentvalues in the public and private sectors. In order to answerthe questions, we first note that the allocative considerationsthat usually motivate government intervention need not requirethe direct provision of services by the government using government-ownedassets. We then argue that the government should own the assetsused to provide the services where the private sector fearsexpropriation by the government, or where ownership conferson the private sector such power as to preclude efficient allocations.Finally, we argue that the discount rate for governments' projectsequals the expected return on comparable investments in thecapital markets. The government should, however, discount pre-taxcash flows at the pre-tax discount rate, for it receives alltax revenues.

Subcontractors for tractors: Theory and evidence on flexible specialization,supplier selection,and contracting

Buyer–Seller networks are pervasive in developing economies yet remain relatively understudied. Using primary data on contracts between the largest tractor assembler in Pakistan and its suppliers we find large variations in prices and quantities across suppliers of the same product. Surprisingly, “tied” suppliers – those that choose higher levels of specific investments – receive lower and more unstable orders and lower prices. These results are explained by developing a simple model of flexible specialization under demand uncertainty. A buyer faces multiple suppliers with heterogeneous types to supply customized parts. Specific investments raise surplus within the relationship but lower the seller's flexibility to cater to the outside market. Higher quality suppliers have a greater likelihood of selling outside and so this cost is greater for them. Therefore even if a buyer typically prefers high types, some low type suppliers might be kept as marginal suppliers because of their greater willingness to invest more in buyer-specific assets. Further empirical examination shows that the more tied suppliers are indeed of lower quality.
