Banking inefficiency in Central and Eastern European countries under a quadratic loss function

We employ a quadratic loss function using a forward-looking rational expectations model to estimate the dynamics of banking inefficiency scores in Central and Eastern Europe (CEE) over the period 1998–2005. Results show that there is heterogeneity in the speed of adjustment to the long run equilibrium across countries and over time, while it appears that the recent accession to the EU has not led to an increase in the speed of adjustment, as it would be expected in light of the integration process prior to the accession. Ownership asserts certain influence on the speed at which banks correct past-period inefficiency.     

Tacit collusion and capacity withholding in repeated uniform price auctions

This article analyzes tacit collusion in infinitely repeated multiunit uniform price auctions in a symmetric oligopoly with capacity‐constrained firms. Under two popular definitions of the uniform price, when each firm sets a price‐quantity pair, perfect collusion with equal sharing of profit is easier to sustain in the uniform price auction than in the corresponding discriminatory auction. Moreover, capacity withholding may be necessary to sustain this outcome. Even when firms may set bids that are arbitrary finite step functions of price‐quantity pairs, in repeated uniform price auctions maximal collusion is attained with simple price‐quantity strategies exhibiting capacity withholding.     

Agricultural exports and the agenda for accelerated development in Africa

In this article the translog cost function with non-neutral parameter shifts is used to study the import demand functions of agricultural commodities which African countries export in competition with other developing regions of the world. It is shown that there has been a systematic bias against the import of these commodities from Africa in favor of importing them from other developing regions. It is then argued that these results support the apprehensions of many African leaders regarding the adoption of a policy of agriculture-based, exportled growth to accelerate economic development on the continent. This article has benefited tremendously from valuable comments and insights by two anonymous referees, the journal editor, as well as Adesina Fadairo and Ki-Ho Kim. All remaining errors are mine.     

Costly Tax Enforcement and Financial Repression

Using an overlapping generations production‐economy model characterized by financial repression, purposeful government expenditures and cost of tax collection, we analyse whether financial repression can be explained by the cost of raising taxes. We show that with public expenditures affecting utility of the agents, modest costs of tax collection tend to result in financial repression being pursued as an optimal policy by the consolidated government. However, when public expenditures are purposeless, the above result only holds for relatively higher costs of tax collection. But, more importantly, costs of tax collection cannot produce a monotonic increase in the reserve requirements. What are critical, in this regard, are the weights the consumer assigns to the public good in the utility function and the size of the government.     

Quantity restrictions and endogenous quality choice

In a vertical product differentiation model under Cournot competition both foreign and domestic firms respond by lowering their investment in long-run quality for a quantity restriction at, and in the neighborhood of, the free trade import level. Average quality increases only when the low-quality foreign firm faces a substantially restrictive quota/voluntary export restraint. The change in quality depends on whether the foreign firm is of high or low quality and upon the restrictiveness of the quota. The imposition of quantity restrictions has important strategic effects on the long-run choice of quality.     

Multidimensional generalized Gini indices

Summary. The axioms that characterize the generalized Gini social evaluation orderings for one-dimensional distributions are extended to the multidimensional attributes case. A social evaluation ordering is shown to have a two-stage aggregation representation if these axioms and a separability assumption are satisfied. In the first stage, the distributions of each attribute are aggregated using generalized Gini social evaluation functions. The functional form of the second-stage aggregator depends on the number of attributes and on which version of a comonotonic additivity axiom is used. The implications of these results for the corresponding multidimensional indices of relative and absolute inequality are also considered.Received: 20 August 2003, Revised: 26 May 2004, JEL Classification Numbers: D63.

Achieving the Millennium Development Goals in Sub‐Saharan Africa: A Macroeconomic Monitoring Framework

This paper presents a macroeconomic approach to monitoring progress toward achieving the Millennium Development Goals (MDGs) in Sub‐Saharan Africa. At the heart of our framework is a macro model which captures key linkages between foreign aid, public investment (disaggregated into education, infrastructure and health), the supply side and poverty. The model is then linked through cross‐country regressions to indicators of malnutrition, infant mortality, life expectancy and access to safe water. A composite MDG Indicator is also calculated. The functioning of our framework is illustrated by simulating the impact of an increase in foreign aid to Niger at the MDG horizon of 2015, under alternative assumptions about the degree of efficiency of public investment. Our approach can serve as the building block for Strategy Papers for Human Development (SPAHD), a more encompassing concept than the current ‘Poverty Reduction’ Strategy Papers.     

The Relative Efficiency of Private and Public Schools: The Case of Thailand

Cost-effectiveness is a key consideration in the policy debateon the appropriate role of private schools in predominantlypublic school systems. This article analyzes the relative performanceof public and private schools in Thailand in enhancing eighthgrade student scores in standardized mathematics tests, givenstudent background and school characteristics. Its main conclusionis that private schools are, on average, more effective andless costly than public schools in improving student performancein mathematics.
