Short-Term Inflation Forecasting Models For Nigeria, Sani I. Doguwa, Sarah O. Alade
Short-Term Inflation Forecasting Models For Nigeria, Sani I. Doguwa, Sarah O. Alade
CBN Journal of Applied Statistics (JAS)
Short-term inflation forecasting is an essential component of the monetary policy projections at the Central Bank of Nigeria. This paper proposes four short-term headline inflation forecasting models using the SARIMA and SARIMAX processes and compares their performance using the pseudo-out-of-sample forecasting procedure over July 2011 to September 2013. According to the results the best forecasting performance is demonstrated by the model based on the all items CPI estimated using the SARIMAX model. This model is, therefore, recommended for use in short-term forecasting of headline inflation in Nigeria. The forecasting performance up to eight months ahead, of the models based on …
An Efficient Two Sample Capture-Recapture Model With High Recaptures, Danjuma Jibasen, Yusuf J. Adams
An Efficient Two Sample Capture-Recapture Model With High Recaptures, Danjuma Jibasen, Yusuf J. Adams
CBN Journal of Applied Statistics (JAS)
This paper proposed an efficient two sample capture-recapture model (Ma) with high recaptures and compared it with the existing models like the model of no factor effect (Mo), behavioral response model (Mb) and the Petersen model (Ms), using simulated data. We found that the Petersen model provides a better estimate of the population size when the observations follow a hypergeometric distribution and the population is overestimated when recapture is high. It was also found that the proposed model provides a better estimator of the population size than the existing ones when the recapture is high. This model is particularly useful …
Causal Relationship Between Stock Market Index And Exchange Rate: Evidence From Nigeria, Abdulrasheed Zubair
Causal Relationship Between Stock Market Index And Exchange Rate: Evidence From Nigeria, Abdulrasheed Zubair
CBN Journal of Applied Statistics (JAS)
This paper uses Johansen’s cointegration to test for the possibility of cointegration and Granger-causality to estimate the causal relationship between stock market index and monetary indicators (exchange rate and M2) before and during the global financial crisis for Nigeria, using monthly data for the period 2001–2011. Results suggest absence of long-run relationship before and during the crisis. The Granger-causality tests show a uni-directional causality running from M2 to ASI before the crisis while during the period of the crisis there is absence of causality between the variables. This suggests that ASI show responsiveness to M2. Thus, absence of the direct …

Investigating Chaos In The Nigerian Asset And Resource Management (Arm) Discovery Fund, Ibiyinka A. Fuwape, Samuel T. Ogunjo
CBN Journal of Applied Statistics (JAS)
This paper investigates chaos in a Nigerian mutual fund, Asset and Resource Management Company Limited (ARM) for a period of eleven years. The existence of chaotic signals in the data was identified by the reconstruction of the phase space of the daily closing price of the fund and the delay time was quantified using mutual information function and the embedding dimension by the false nearest neighbours, where the values were identified to be 15 and 20 respectively. The presence of chaotic signals in the ARM data was further confirmed by the correlation dimension method which yielded a dimension of 2.2 …

This work considers the application of Periodogram and Fourier Series Analysis to model all-items monthly inflation rates in Nigeria from 2003 to 2011. The main objectives are to identify inflation cycles, fit a suitable model to the data and make forecasts of future values. To achieve these objectives, monthly all-items inflation rates for the period were obtained from the Central Bank of Nigeria (CBN) website. Periodogram and Fourier series methods of analysis are used to analyze the data. Based on the analysis, it was found that inflation cycle within the period was fifty one (51) months, which coincides with the …
Nigerian Stock Index: A Search For Optimal Garch Model Using High Frequency Data, Olaoluwa Simon Yaya
Nigerian Stock Index: A Search For Optimal Garch Model Using High Frequency Data, Olaoluwa Simon Yaya
CBN Journal of Applied Statistics (JAS)
This paper attempts to fit the best Generalized Autoregressive Conditional Heteroscedastic (GARCH) model for All Share Index (ASI) of Nigerian Stock Exchange (NSE) returns. A search is made on various GARCH variants specified on the assumptions of stationarity and asymmetry. Fractionally integrated types are also considered to capture the possibility of return series having property of long range dependency. The parameter estimations are carried out on the assumptions of normality and non-normality of GARCH innovations, with models and forecasts evaluated using information criteria and loss functions respectively. Under normality assumption, Hyperbolic GARCH (HYGARCH(1,d,1)) model is selected and Integrated GARCH (IGARCH(1,1)) …

Time Series Modeling Of Nigeria External Reserves, Iheanyichukwu S. Iwueze, Eleazar C. Nwogu, Valentine U. Nlebedim
CBN Journal of Applied Statistics (JAS)
This paper discusses the levels and trend of external reserves in Nigeria. The relevance of this lies in the fact that it could help to monitor the reserves and throw early warning signal about any economic crisis. Monthly data on Nigeria external reserves for the period January 1999 to December, 2008 derived from the 2008 CBN Statistical Bulletin was analyzed using ARIMA model. Results of the analyses show that (i) the data requires logarithmic transformation to stabilize the variance and make the distribution normal (ii) the appropriate model that best describes the pattern in the transformed data is the Autoregressive- …
A Markov Decision Process Approach To Optimal Control Of A Multi-Level Hierarchical Manpower System, Akaninyene U. Udom
A Markov Decision Process Approach To Optimal Control Of A Multi-Level Hierarchical Manpower System, Akaninyene U. Udom
CBN Journal of Applied Statistics (JAS)
A recurrent problem in manpower control is how to attain the desired structural configuration in an optimal way, since it is possible to reach a desired structural configuration using different control inputs. The major aim of this paper is to develop a Markov Decision Process for optimal control of a Multi-level Hierarchical Manpower System (MHMS) by promotion and interdepartmental transfers. This is examined under control by intervention and contraction cost Markov Decision Process.
Two Studies On Childhood Obesity: Effect Of Obesity On Academic Achievement And Effect Of Food Store Access On Diet Quality, Gaogao Yu
Graduate Theses and Dissertations
This thesis includes two studies on childhood obesity. This first study investigates whether childhood obesity rates affect their academic achievement scores by using a school-level panel data set on Arkansas 4th and 6th grades. The main results indicate that childhood obesity rates do not significantly affect academic achievement scores. Controls for education inputs such as library volume, educational expenditures per student and teacher salary show consistently significant positive relationship to students' test scores in both whole sample and in subsample analyses by socio-economic and minority status. The second study examines the effect of a neighborhood food environment feature, specifically food …

The Contribution Of Finance To Agricultural Production In Nigeria, O. M. Mbutor, R. E. Ochu, I. I. Okafor
Economic and Financial Review
Several studies have found a positive correlation between agricultural financing and the performance of the agricultural sector. But fewer efforts have been directed at sieving out the agricultural output that is exclusively associated with the extent of funding. This study aimed to ascertain the actual portion of total agricultural output that could be attributed to agricultural financing in Nigeria. The vector error correction methodology was applied following the nature of data properties. The results showed a positive effect of finance on agricultural output. However, variance decomposition revealed the poor state of agricultural financing with a disproportionate dependence of the sector …

Graduate Theses and Dissertations
This study examines the relationship between food insecurity and Social capital among 5th-7th graders attending an intermediate school in Northwest Arkansas where nearly 70 percent of students participate in the free or reduced lunch program. The central research questions are: Does Social capital have a direct impact on children's food insecurity? And, does Social capital mediate the influence of negative circumstances on children's food insecurity? This study finds that Social capital does have a significant association with food insecurity, even when controlling for multiple demographic and circumstantial factors. However, there appears to be no mediation of circumstance by Social capital. …

Local Food And Agriculture Awareness: The Literacy Of Local Produce And Agriculture In Northwest Arkansas, Kyle Colton Flynn
Graduate Theses and Dissertations
The Center for Disease Control and Prevention (CDC) suggests that adolescents and children, both male and female, are failing to meet the daily fruit and vegetable consumption requirements (Kim et al., 2011; Upton et al., 2012; Harris et al., 2012). Other studies have shown that with increased exposure and availability of produce, students (K-5) tend to consume more fruits and vegetables (Cullen et al., 2009; Evans et al., 2012). The purpose of this study is to identify whether Northwest Arkansas eleventh grade high school students possess experience and knowledge of local produce and agriculture. Out of 1054 students enrolled at …

Public-Private Regime Interactions In Global Food Safety Governance, Ching-Fu Lin
Public-Private Regime Interactions In Global Food Safety Governance, Ching-Fu Lin
Transnational Business Governance Interactions Working Papers
In response to an apparent decline in global food safety, numerous public and private regulatory initiatives have emerged to restore public confidence. This trend has been particularly marked by the growing influence of private regulators such as multinational food companies, supermarket chains and non-governmental organizations (NGOs), who employ private standards, certification protocols, third-party auditing, and transnational contracting practices. This paper explores how the structure and processes of private food safety governance interact with traditional public governance regimes, focusing on Global Good Agricultural Practices (GlobalGAP) as a primary example of the former. Due to the inefficiency and ineffectiveness of public regulation …

Law Faculty Scholarship
By 2050, the Philippine population is projected to increase by as much as 41 percent, from 99.9 million to nearly 153 million people. Producing enough food for such an expanding population and achieving food security remain a challenge for the Philippine government. This paper argued that intellectual property rights (IPR) can play a key role in achieving the nation’s current goal to be food-secure and provided examples to illustrate that the presence of sound intellectual property (IP) helps foster research, development, and deployment of agricultural innovations. This paper also offered key recommendations about how the IP system can be further …

Measurement Of The Effect Of Policy Changes On Volatility In Dairy Markets1, Eoin Kelly, Declan O'Connor, Michael Keane
Irish Business Journal
Volatility in dairy commodity markets has become a major concern for many in the dairy supply chain and is likely to remain so in the future. Changes to the Common Agricultural Policy (CAP) over the past decade have more closely aligned EU and World prices and their associated volatilities. The aim of this paper is to measure volatility at farm level in Ireland over time, identify possible reasons for the increased volatility and identify ways of reducing volatility. Statistical measures such as coefficient of variation (CV) and annualised standard deviation are used to provide measures of past volatility and its …

There is a growing sense of the fragility of agricultural production in the Global North and South and of increasing risks to food security, as scientific observations confirm significant changes in the Gulf Stream, polar ice, atmospheric CO2, methane release, and other measures of climate change. This sense is heightened as each of us experiences extreme weather, such as the increasing frequency of droughts, floods, unseasonal temperatures, and erratic seasonality. The central research challenge before us is how global, national, regional, and local food systems may adapt to accelerating climate change stresses and uncertainties to ensure the availability, …

Hunger is one of the major problems in several countries, and the objective to reduce it has become a global concern. A major initiative of the United Nations Millenium Development Goals (MDG) is the eradication of extreme poverty and hunger. However, the attempt to reduce the abovementioned issues, calls for proper identification as to who the impoverished and hungry are. There are several ways to identify the poor, but pinpointing who the hungry are, is another task.

Future food production will be constrained by the scarcity of fossil fuel and fresh water as well as increasing intensity and unpredictability of weather events and climate changes. The assurance of food security and equity for many consumers is complicated by concentration of ownership of land and other production resources, as well as a global corporate food systems model that is driven by profit at the expense of people and the environment. To assess potential alternatives to the contemporary global food chain, well focused research is needed on local food production and food webs where small- and midscale family farms …
