The Leverage Theory of Tying Revisited: Evidence from Newspaper Advertising

Data from the Canadian newspaper-advertising industry is used to assess the private profitability of tying in a market where the standard efficiency motives (e.g., price discrimination, cost saving, and quality control) are unlikely to apply. The empirical assessment is based on a model of leveraging in which suppliers of the tied good are paid a commission rather than a fee for service. This model demonstrates that tying is profitable under a wide range of circumstances. Furthermore, it is found that, with newspapers, tying and monopoly power go hand in hand.     

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     

Capital Structure and Bank Performance: Empirical Evidence from Ghana

The aim of this paper is to examine the impact of capital structure on profitability of commercial banks in Ghana. The study used a sample of 21 commercial banks over the period 2000–2014 using panel corrected standard errors and two‐stage least‐squares estimation approaches. The results show that bank capital structure measured as capital‐to‐asset ratio is a robust and positive driver of bank performance (profitability) measures (return on assets and net interest margin). Additionally, the results further indicate that share of customer demand deposit positively affects bank profitability. The positive relationship between the capital‐to‐asset ratio and performance provides support for the bank capitalization policy implemented by the Bank of Ghana. Also, the findings provide evidence in support of the recent upsurge in bank short‐term deposit mobilization strategies and promotions by commercial banks in the country to enhance their deposit base.     

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.     

Determinants of Government Aid to Katrina Survivors: Evidence from Survey Data

We analyze survey data from Mississippi coastal communities where Katrina made its final landfall. Logistic regressions indicate that government aid is helpful in dealing with one- to two-month economic disruption and long-term rebuilding but is less helpful with regard to short-term rebuilding and mitigating longer-term disruption. Our analysis (including a basic risk assessment) finds evidence that individuals receiving government aid and/or having a disability predisaster are likely to incur severe economic hardship postdisaster and that individuals with greater predisaster economic and/or social network capital seem to be less at risk. Our results underscore the importance of housing in the resumption of basic economic activity.     

The Impact of Foreign Agricultural Aid and Total Foreign Aid on Agricultural Output in African Countries: New Evidence from Panel Data Analysis

Official Development Assistance may play an important role in increasing the resources to finance the agriculture sector and improve agricultural outcomes in African countries. Although this is a relevant issue, very few studies have investigated the link between foreign agricultural aid and national agricultural output. Using advanced econometrics techniques, this paper examines the impact of foreign agricultural aid and foreign aid on agriculture output in the panel data set of 29 African countries over the period of 1975–2013. In particular, we employed two estimation methods: Augmented Mean Group and Common Correlated Effects‐2SLS. The first method accounts for heterogeneous slope coefficients across group members and cross‐sectional dependency among variables, whereas the second method accounts for endogenous regressors. Our main findings indicate a small and positive impact of foreign agricultural aid and total foreign aid on agricultural output for low‐ and middle‐income countries. Furthermore, the Pairwise Dumitrescu‐Hurlin Panel Causality test shows evidence of a bidirectional causal relationship between agricultural aid and agricultural output for the full sample, noting that the result changes at the different group income level. Based on the empirical results, recommendations for future policy are given.
