Additional Empirical Evidence on Real Convergence: A Fractionally Integrated Approach

We examine the real convergence hypothesis for 14 OECD countries looking at the fractional order of integration of the differences of real GDP per capita in these countries with respect to the United States. Using parametric procedures, the results vary depending on how we specify the I(0) disturbances. If they are white noise, convergence is achieved for Canada and Australia, and with autocorrelated disturbances, this hypothesis is satisfied for France and the Netherlands. However, allowing for a break at World War II, evidence of convergence is obtained for all countries. JEL no. C32, O41     

Aid Modalities and Budgetary Response: Panel Data Evidence

We investigate the budgetary effects of project and program financing on the behavior of recipient governments. For this purpose, we developed a simple fiscal response model. The solution of the model is then tested using panel data techniques for a relatively large sample of 106 aid-recipient countries spanning the period 1970–2001. With respect to public expenditure, our results suggest that the impacts of project aid and financial program aid on total expenditure are positive and statistically significant. In terms of the composition of total expenditure, we find that project aid flows are associated with increases in capital expenditure while financial program aid is associated with an increase in government consumption. Turning to the revenue side we found no evidence that aid flows, project or financial program aid, are associated with a reduction in taxation effort. The evidence also shows that project aid flows are associated with an increase in trade tax. JEL no. F35, H2, H5     

Aid and economic growth in LDCs: Evidence from Sub-Saharan Africa

This paper uses a disaggregated cross-national time-series aid data and a Least Squares Dummy Variables (LSDV) model to investigate the effects of aid on economic growth in Sub-Saharan Africa. We find that, contrary to what some critics of aid argue, aid has a small but positive and significant effect on economic growth in Sub-Saharan Africa. A simultaneous equation specification of the model shows that aid affects economic growth in Sub-Saharan Africa directly and indirectly through increased domestic savings and investment.     

Privatization and Labor Cost Savings: Evidence from Health Care Services

This study examines whether privatization is associated with low public sector health care wages and with low probability of public sector employment for health care providers. Findings suggest that privatization contributes significantly to low wages of union health care providers in the public sector. Privatization also contributes to a low probability of public sector employment in this industry, especially to unionized workers. These results indicate that competition enhancing policy can promote lower labor costs even in a service sector that employs a highly skilled work force.

Fixed Cost Magnitude,Fixed Cost Reporting Format,and Competitive Pricing Decisions: Some Experimental Evidence*

Although neoclassical economic theory predicts that fixed cost magnitude and fixed cost reporting format will not influence short‐term pricing decisions, these factors systematically affected pricing decisions in a duopoly experiment. Increasing fixed cost magnitude (a pure sunk cost in this study) across experimental conditions caused participants to first lower, then raise, competitive prices. Consistent with the psychological phenomenon of loss aversion, this change in pricing behavior reduced the frequency of reported losses. This study further reveals that the accounting format for reporting fixed costs influenced pricing behavior. Specifically, participants receiving capacity costing feedback reports established increasingly lower selling prices relative to the prices established by participants receiving contribution margin feedback reports. Given that a very simple cosmetic reporting manipulation produced increasingly significant competitive pricing differences in a market setting, this study provides evidence that functional fixation is not necessarily eliminated by market forces.     

Transaction Cost Economics: How It Works; Where It is Headed

This paper begins with a sketch of the New Institutional Economics, with special emphasis on the institutional environment (North and others) and the institutions of governance (Coase and others). Thereafter the paper mainly emphasizes the applications of transaction cost economics to the study of governance, the object being to effect an economizing alignment between transactions, which differ in their attributes, and governance structures (firms, markets, hybrids, bureaus), which differ in their cost and competence. I raise a series of issues – phenomena of interest, describing human agents, describing firms, purposes served, scaling up – to which any would-be theory of the firm should be expected to speak and indicate how transaction cost economics responds to each. I thereafter describe the mechanisms through which transaction cost economics is implemented and develop some of the core conceptual supports out of which it works. Applications to public bureaus, strategic management, and intractable transactions are sketched.

Aid Effectiveness,Debt Relief and Public Finance Response: Evidence from a Panel of HIPC Countries

Substantial amounts of debt relief have been granted to a set of low-income countries, as an alternative aid modality. Although the theoretical case for debt relief is firmly established, only empirical analysis can show whether debt relief is indeed a (more) effective mode of aid delivery. We investigate the linkages between debt relief and other fiscal variables such as current expenditure, government investment, taxation and domestic borrowing, in comparison to the effects of grants and concessional loans. We find that the fiscal impact of HIPC debt relief follows fairly complex dynamics. For example, debt relief initially reduces government investment, but the effect becomes positive after two years, well outperforming other modes of aid delivery. JEL no. F34, F35, O11, O19
