Mobile Telephony,Financial Inclusion and Inclusive Growth

ABSTRACT

The paper employs the multipurpose nature of mobile telephony to investigate its welfare implications using a large sample of households in Ghana. We use seemingly unrelated probit and instrumental variable procedure to test for two related issues: First, we investigate whether mobile telephony promotes pro-poor development by helping households to efficiently allocate consumption and navigate out of poverty. Second, we analyze whether access to a broad array of financial services enhances the capacity of households to live worthwhile lives. The results show that mobile penetration and financial inclusion significantly reduce the probability of a household becoming poor and increase per capita household consumption of food and non-food items. Our results show that the welfare benefits of mobile telephony and financial inclusion are not more pronounced in female-headed households. These insights serve as useful guide for government and other stakeholders who are looking for avenues to improve livelihoods.     

Optimal wage re-negotiation in a closed and open economy

This paper investigates an economy in which there are short-term wage contracts that are re-negotiated under certain conditions. The paper determines the optimal frequency of wage re-negotiation and shows that it depends positively on measures of aggregate variability and Phillips curve slope. The role of optimal wage re-negotiation is to mitigate the output effects of various shocks. In the context of an open economy, it is shown that the desirable exchange rate regime in an economy with optimal wage re-negotiation depends on the stochastic structure of the economy.     

Agricultural market policy reforms and growth in Nigerian export crops

The paper investigated the prospect of selected export crops in meeting the demand of emerging commodity and futures market in Nigeria within the context of a counterfactual model, The data covered about three decades （1973-2000）. The model was estimated to capture two economic policies in the period namely stabilization （1973-1985） before introduction of Structural Adjustment Programme （SAP） and liberalization policy （1986-2005） that followed SAP The results indicated positive divergence between factual and counterfactual trends for palm kernel, cocoa, coffee and rubber but neuative for groundnut after SAP     

Basic human needs: The plateau curve

The satisfaction of basic human needs in developing countries follows a nonlinear curve relative to per capita income, asymptotically approaching a limiting level. Within this general relationship, some countries are more ‘efficient’ than others in improving basic needs at lower per capita income levels. Infant mortality rates in 116 countries, from 1950 to 1980, are analyzed to identify factors affecting a country's efficiency in reaching infant mortality targets relative to its Gross Domestic Product per capita. The determinants of efficiency include export structure, internal distribution, late development and access to education. Implications for development policy are discussed.     

Food Insecurity and Hunger in the Kindergarten Classroom: Its Effect on Learning and Growth

This study investigates the correlation between food insecurity, educational achievement, and health among kindergarten children in the United States. Data from the Early Childhood Longitudinal Study—Kindergarten Cohort are used to analyze educational achievement and physical growth of kindergartners faced with food insecurity. The results demonstrate that children begin to experience the effects of food insecurity even at the most marginal level of household food deprivation. Children in households with any signs of food insecurity score lower and learn less during the school year.     

Proprietary costs and sealing documents in patent litigation

We study whether the sealing of a defendant’s judicial records during a patent lawsuit filing correlates with the defendant’s level of competition and disclosure. Courts permit sealing of judicial records when competitive damage outweighs the public interest in access to documents and records. We find that defendants with sealed judicial records have higher research and development (R&D), lower industry sales concentration, and more references to competition in their annual reports than defendants without sealed judicial records. We observe faster mean reversion of return on net operating assets when courts seal defendant records. The results suggest that sealing relates to archival measures of competition. Finally, consistent with proprietary costs restraining disclosure, we find that defendants with sealed judicial records are less likely to issue management forecasts, file 8-Ks less frequently, and have longer and less readable 10-Ks.     

Auditor selection within a business group: evidence from Taiwan

Although auditor selection is well documented in the literature, it is unclear whether group characteristics affect firms’ auditor selection decisions. Generally, a business group is the result of diversification by the core firm. Major decisions of the business group, such as auditor selection, are made by the core firm and influenced by the business group’s characteristics. Using operational and ownership linkages perspectives, this study investigates the determinants of a business group’s member firm engaging the same auditor as its core firm. We employ the input–output relationship of products along a supply chain to construct product vertical relatedness measures between member firms and the core firm, and establish logistic regression models to test our hypotheses. Using a sample of publicly listed business groups in Taiwan from 2000 to 2010, our results suggest that a member firm is more likely to engage the same auditor as its core firm when (1) the core firm engages a Big N auditor, (2) the core firm’s auditor is an industry specialist for both the core firm and its member firm, (3) the degree of vertical relatedness increases, or (4) the controlling shareholders’ deviation of voting rights from cash flow rights increases (hereafter deviation). On the other hand, the likelihood of a member firm engaging the same auditor as its core firm when induced by higher deviation could be offset by the influence of stronger business vertical linkages.
