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 …

Subsidizing Non-Polluting Goods Vs. Taxing Polluting Goods For Pollution Reduction, Robert S. Main

Scholarship and Professional Work - Business

Pigovian taxes on polluters are politically unpopular, but subsidies for non-polluting sources are politically attractive. This paper presents a linear demand and supply model and numerical example to explore the trade-offs between taxing polluting sources of a good versus subsidizing non-polluting sources of the same good. While the model (along with the associated numerical example) shows the optimality of Pigovian taxes, it also shows how much welfare is reduced if subsidies for nonpolluters are employed instead. Further, it shows the optimal tax, given any level of subsidy and the optimal subsidy, given any level of tax.

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

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 …

Modeling The Nigerian Inflation Rates Using Periodogram And Fourier Series Analysis, Chukwuemeka O. Omekara,, Emmanuel J. Ekpenyong, Micheal P. Ekerete

CBN Journal of Applied Statistics (JAS)

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

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

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.

Minimum Investment Requirement, Financial Integration And Economic (In)Stability: A Refinement To Matsuyama (2004), Haiping Zhang

Research Collection School Of Economics

This note proposes a simple, more precise, necessary condition for symmetry breaking in Matsuyama (Financial Market Globalization, Symmetry-Breaking, and Endogenous Inequality of Nations, Econometrica, 2004 ), i.e., the positive interest rate response to income changes, which essentially arises from the assumptions of financial frictions and minimum investment size requirement of individual projects. This condition also holds under the more general settings. Thus, this note o ers an empirically testable hypothesis, i.e., Matsuyama's symmetry breaking is more likely, if the interest rate response to income changes is positive and sufficiently large.

Detecting Bubbles In Hong Kong Residential Property Market, Matthew S. Yiu, Jun Yu, Lu Jin

Research Collection School Of Economics

This study uses a newly developed bubble detection method (Phillips, Shi, and Yu, 2011) to identify real estate bubbles in the Hong Kong residential property market. Our empirical results reveal several positive bubbles in the Hong Kong residential property market, including one in 1995, a stronger one in 1997, yet another one in 2004, and a more recent one in 2008. In addition, the method identifies two negative bubbles in the data, one in 2000 and the other one in 2001. These empirical results continue to be valid for the mass segment and the luxury segment. However, this method has …

Do Major League Baseball Hitters Engage In Opportunistic Behavior?, Heather M. O'Neill

Business and Economics Faculty Publications

This study focuses on 256 Major League Baseball free agent hitters playing under the 2006–2011 collective bargaining agreement to determine whether players engage in opportunistic behavior in their contract year, i.e., the last year of their current guaranteed contracts. Past studies of professional baseball yield conflicting results depending on the econometric technique applied and choice of performance measure. When testing whether players’ offensive performances increase during their contract year, the omitted variable bias associated with OLS and pooled OLS estimation leads to contrary results compared to fixed effects modeling. Fixed effects regression results suggest players increase their offensive performance subject …

Macroeconomic And Political Determinants Of Foreign Direct Investment In The Middle East, Robin Barnaby Calver

Dissertations and Theses

This study argues that governments with sustained GDP growth, open markets, low country risk, high levels and low standard deviation of government performance, and few or no occurrences of war, will see larger levels of foreign direct investment (FDI) over time. Scholarship on the determinants of FDI variously argues the influence of GDP growth, the openness of a country's economy, a government's level of political capacity, the level of country risk, and the negative effects of inter-, intra- and extrastate conflict. These studies on the various effects on FDI, while providing insightful and substantial statistical results, fail to capture the …

Policy Responses In An Unstable Globalized Economy: Multi-Stressed Low-Earning Families In Singapore, Irene Y. H. Ng, Kong Weng Ho

Research Collection School Of Economics

The Singapore government responded swiftly to the 2008 global recession, doling out a range of policies in aid of all levels of wage earners. This paper explores the impacts of economic trends and government policies on low-wage earners. Using a theoretical model and empirical data from a pilot study of recipients of a government Work Support Program, it demonstrates the effects of socioeconomic factors on multi-stressed low-earning families. It discusses the adequacy of current policies in addressing the multiple stressors experienced by low-wage earners.

Transition To Full-Fledged Inflation Targeting: A Proposed Programme For Implementation By The Central Bank Of Nigeria, Michael O. Ojo

CBN Occasional Papers

This paper attempts to provide an input into addressing these issues, especially as regards resolving the technical, administrative and practical problems for a transition to inflation targeting as a framework for monetary policy in Nigeria. Specifically, the main purpose of this paper is to outline proposals that would permit the CBN transit successfully to full-fledged inflation targeting (FFIT) for its monetary policy operations. Following the introduction (Section 1), the paper is organized as follows: Section 2 examines the conceptual framework, focusing on the essential elements and modalities of different monetary policy frameworks. Section 3 contains an overview of the experiences …

An Analysis Of The Monetary Policy Transmission Mechanism And The Real Economy In Nigeria, Eddy C. Ndekwu

CBN Occasional Papers

The study is an empirical analysis which seeks to explain the monetary policy transmission mechanism to the real economy in Nigeria. It examines the process by which the interest rate policy of the Central Bank of Nigeria actually affects the structure of interest rates, credit, aggregate demand and output production and, hence, changes in inflation rate. In the analysis, we review the paradigm of the channels of monetary policy transmission mechanism by studying over two and-half dozen cases of empirical studies in the economic literature. By applying vector auto-regression (VAR) with dynamic logarithmic form and the ordinary least squares (OLS) …

The Disparate Neighborhood Impacts Of The Great Recession: Evidence From Chicago, Sonya Williams, George C. Galster, Nandita Verma

Urban Studies and Planning Faculty Research Publications

We advance scholarship about how macroeconomic forces differentially manifest themselves across local spaces by developing a holistic conceptual framework and empirical analyses involving multilevel change modeling. Unlike prior work, we examine differential rates of change in neighborhood indicators. We illustrate our approach with Chicago data measuring the crime, housing, and economic domains of neighborhood quality- of-life over the 2000-2009 period. We find that the local dynamic manifestations of macroeconomic cycles were far more nuanced than have been previously observed. Neighborhood indicators moved along distinct trajectories, sometimes but not necessarily tracking each other or the overall business cycle, and they changed …

Structural Change And Real Output Growth In Nigeria: A Cointegration Analysis, P. D. Golit

Economic and Financial Review

The study employed the Johansen (1988) and the Johansen and Juselius (1990) multivariate maximum likelihood method within a Vector Autoregressive framework to explore the impact of structural reforms on the level of real output in Nigeria. We fit the equation separately for two sub-samples, the pre-reform and the market-reform periods, to enable comparisons of the outcomes under alternative policy regimes. We further estimate the model using data that covered the entire sample period to evaluate the total effects and include a dummy variable to capture the impact of the policy shift. The Johansen cointegration test confirms the existence of long-run …

Cost-Effective Estimation Of The Population Mean Using Prediction Estimators, Tomoki Fujii, Roy Van Der Weide

Research Collection School Of Economics

This paper considers the prediction estimator as an efficient estimator for the population mean. The study may be viewed as an earlier study that proved that the prediction estimator based on the iteratively weighted least squares estimator outperforms the sample mean. The analysis finds that a certain moment condition must hold in general for the prediction estimator based on a Generalized-Method-of-Moment estimator to be at least as efficient as the sample mean. In an application to cost-effective double sampling, the authors show how prediction estimators may be adopted to maximize statistical precision (minimize financial costs) under a budget constraint (statistical …

Inflation Targeting And Growth: The Role Of The Tradable Sector, Luis Monroy Gómez Franco

Undergraduate Economic Review

This paper provides an analytical explanation to the empirical association between monetary policy conducted according to the inflation targeting (IT) framework and the appreciation of the exchange rate, relating it to the literature on the effects of the exchange rate on growth. A two sector small open economy model is developed in which the behavior of the non tradable inflation and the nominal exchange rate are analyzed. The results indicate that the response to inflation variance under the IT regime causes the appreciation trend. Since this trend is not reversed immediately, increasing returns in the tradable sector affect capital accumulation.

Can Neoclassical Trade Theory Explain Congressional Voting?, John Dellipriscoli

Master's Theses

The neoclassical trade model has notoriously been unable to empirically predict trade flows throughout the world, however there has been a notion that the same theories and predictions could also be applied to democratic voting on free trade legislation. Using roll-call votes on three 2011 United States bilateral trade agreements with Colombia, Panama, and South Korea, respectively, a simple empirical model based on the neoclassical concepts, specifically the Heckscher-Ohlin and Stolper-Samuelson corollary theorems, is outlined. After an analysis using a logit estimation method, it is revealed that there is conflicting evidence whether the voting on the 2011 free trade agreements …

The Changing Dynamics Of The Employment Gap And Its Macroeconomic Implications, William Brian Gowen

Honors Projects in Economics

There has been much discussion about the sluggish economic recovery out of the recent recession. However, the lag in employment growth is not unique to the most recent recovery. Jobless recoveries have plagued the U.S. economy over the last three business cycles. The reasons for this change have remained largely inconclusive, with several factors highlighted in the current literature. This paper uses Vector Autoregression (VAR) to analyze the employment gap in the United States over the past six decades. Unlike previous studies, it accounts for the most recent recession while also addressing alternative explanations - trade and globalization, government employment, …

Jobs Don’T Grow On Trees, Nicholas Johnson

Undergraduate Research Symposium 2013

Most contemporary macroeconomic models account for unemployment by making the simplifying assumptions that 1) there is an equilibrium level of unemployment and that 2) when the economy is not at that level it will tend towards equilibrium. Implicit in these models is also the assumption that the actual behavior of unemployment does not affect the equilibrium level. This paper joins a growing number of economists pointing out that such assumptions are false: the equilibrium does depend on past behavior, a trait called hysteresis. This paper considers the hysteresis hypothesis by using an iterated version of OLS to construct a series …

Decomposing The Changes Of The Divisia Price Index: Application To Inflation In The Philippines, Tomoki Fujii

Research Collection School Of Economics

We decompose the logarithmic change in the Divisia price index into the pure price, substitution, and preference effects, although the latter two effects are hard to distinguish in practice. This decomposition allows us to identify the incidence and contributing factors of inflation. In the Philippines, we find that the preference effect is much smaller than the pure price effect in all provinces. We also find that rich deciles have experienced a higher inflation than poor deciles between 1988 and 2006. However, the gap in the standards of living has actually widened because poor deciles lagged behind in consumption growth.

The Macroeconomic Effect Of Currency Union Dissolution: Evidence From The Narrative, Marcus Josefsson

Honors Theses

In the face of the growing importance of alternative monetary arrangements throughout the world, the economics literature contains contradictory explanations for the impact of currency union dissolution. Some argue that dissolving a union removes limitations to growth, while others contend that the ensuing uncertainty drives weaker macroeconomic performance. In this paper, I present empirical analysis of the macroeconomic effect of dissolving currency unions. I utilize a narrative approach to address asymmetries in the underlying motivations for different dissolutions, and find that the absence of economic concerns driving dissolution leads to improved growth in the post dissolution period. Further, evidence for …

Does Exchange Market React To Central Bank Governor Replacements: Evidence From A New Dataset Using Narrative Approach, Siyang Xu

Honors Theses

This paper contributes to the literature that analyzes the exchange market reaction to the event of a central bank governor replacement. In order to solve the endogeneity problem, we develop a narrative approach-based on reports from credible newspapers-that classifies central bank governor replacements by their nature and causes. Using this new dataset on central bank independence for 31 countries over the period 1967-2012, we decompose all replacements into endogenous and exogenous cases with respect to inflation and financial market performance. We find that such a distinction is critical in understanding the exchange market reactions. We show that i) endogenous replacements, …
