The effects of fuel prices and vehicle sales on fuel‐saving technology adoption in passenger vehicles

Although economic theory suggests that both sales and fuel costs affect technology adoption by vehicle manufacturers, there is very little empirical evidence on either effect. We document a strong connection between a vehicle's sales and its energy efficiency. Using a demographics‐driven demand shifter to isolate demand‐side changes in sales, we find that a one standard deviation increase in sales raises efficiency by 0.2%, compared with a mean improvement rate of 1.4% per year between 1997 and 2013. Higher fuel prices also increase technology adoption directly by increasing willingness to pay for fuel cost savings. The results have two implications: manufacturers will continue to focus technological improvements on top selling vehicles; and fuel taxes will have larger effects on technology adoption than fuel economy standards and feebates.

Women's empowerment and child health outcomes in Ghana

This study investigates whether women's empowerment, measured by education attainment relative to her partner, decision‐making, and domestic violence is related to nutritional status of children in Ghana. Using the 2014 Ghana Demographic and Health Survey, the study examines the effect of women empowerment on child's nutritional status at different points in its conditional distributions using ordinary least squares and quantile regression estimation technique. The study observes that women's empowerment is associated with improvement in the nutritional status of children with Z‐scores less than ?4 and ?3 standard deviations, for acutely and severely malnourished children respectively in the long run. The study recommends that the Ministry for Gender and Social Protection should educate male partners on the need for women participation in decision‐making at the household level as well as make formal education accessible to women.     

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.
