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
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)) …

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.

A Study Of Household Finance In China, Zhen Huang
Lingnan Theses
The emerging field of household finance, which studies the welfare benefits of financial markets for households and how effectively households use this market, is of significant importance for both academics and policy makers. However, studies in this new field remain scarce. Using data from a national representative survey that is unique for its combination of abundant household characteristics and heterogeneous individual preferences, attitudes and believes, and for its inclusion of investment behaviour and performances, this thesis pioneers a positive household finance study in developing countries by systematically investigating Chinese householders’ investments in the stock market. Moreover, this is the first …

We conceptualize structure in personal consumption by explicitly defining categorizations of goods and services that consumers typically make in defining and organizing these objectives in their heuristics. Results from estimation of an Almost Ideal (AI) Demand System in each of two study periods generally support the structural differentiation of consumption goods.

Examining The Low Volatility Anomaly In Stock Prices, Munish Malhotra
Electronic Theses and Dissertations
Modern portfolio theory states that investments with greater beta, a common measure of risk, require greater returns from investors in order to compensate them for taking greater risk. Therefore, under the premise that market participants act rationally and therefore markets run efficiently, investments with higher beta should generate higher returns vis-à-vis investments with lower beta over the long run. In fact, many studies suggest that investments with lower beta actually generate equal to or higher returns relative to investments with higher beta. In looking at data for the S&P 500 going back 22 years between 1990 and 2012, this study …

Strategies Of Cooperation And Punishment Among Students And Clerical Workers, Maria Bigoni, Gabriele Camera, Marco Casari
Economics Faculty Articles and Research
We study the individual behavior of students and workers in an experiment where they repeatedly face the same cooperative task. The data show that clerical workers differ from college students in overall cooperation rates, strategy adoption and use of punishment opportunities. Students cooperate more than workers. Cooperation increases in both subject pools when a personal punishment option is available. Students are less likely than workers to adopt strategies of unconditional defection, and more likely to select strategies of conditional cooperation. Finally, students are more likely than workers to sanction uncooperative behavior by adopting decentralized punishment, and also personal punishment when …

How does retirement influence subjective well-being? Some studies suggest retirement does not affect subjective well-being or may improve it. Others suggest it adversely affects it. This paper aims at advancing our understanding of the effect of retirement on subjective well-being by (1) using longitudinal data to tease out the retirement effect from age and cohort differences; (2) using instrumental variables to address potential reverse causation of subjective well-being on retirement decisions; and (3) conducting cross-country analyses, exploiting differences in eligibility ages for retirement benefits across countries and within countries. We use panel data from the US Health and Retirement Study …

One-fifth of children aged below five with employed mothers benefit from grandparent provided child care as their main source of daycare in the U.S. Using data from the Health and Retirement Study, we investigate how grandchild care needs relate to intergenerational transfers of time and money and grandparents’ labor supply behavior. We find that grandparents with a new born grandchild are more likely to provide grandchild care while married grandparents are also more likely to be employed and provide financial help. Grandparents with grandchildren living close by provided higher time transfers while married grandmothers with resident grandchildren also worked longer …

A Spatial Analysis Of The Italian Second Republic, Massimiliano Landi, Ricardo Pelizzo
Research Collection School Of Economics
The Optimal Classification method is applied to a newly created data set to provide a spatial map of the Italian Second Republic (1996–2008). A bi-dimensional political space was found in the XIII Legislature and virtually a one-dimensional political space in the XIV and XV Legislatures. In addition, the main dimension is explained along the government–opposition dimension rather than on the traditional left–right dimension. During the Second Republic, Italy experienced changes in the electoral system and in the format of parties. The data are used to discuss the implications of either change on the dimensionality space. It was found that the …

Valuation Of The Ecosystem Services Provided By Coastal Ecosystems In Shandong, China: Developing A Non- Market Valuation System, Jing Guo
Working Papers
Non-market valuation assesses the contributions of ecosystem services to human well-being by determining the preference of users. That is how much money users are willing to pay for ecosystem improvements or how much they are willing to accept for ecosystem losses. Through exploring these preferences, the natural capital can be accounted for economically and quantitatively. It can not only lead to better understanding of ecosystem benefits, but also make it possible to compare ecosystem services with other conventional goods and services (e.g. real estate) in monetary terms.
Shandong is a coastal province of China, which is located on the eastern …

Do Mlb Hitters Boost Performance In Their Contract Year?, Heather M. O'Neill
Business and Economics Faculty Publications
This study focuses on 256 MLB free agent hitters playing under the 2006-2011 CBA to determine whether they boost their offensive performance in their contract year. Prior studies’ results are mixed, depending on the econometric technique used and the choice of the offensive performance measure.
Having multiple year observations per player, one can incorporate the unobserved traits of the players (ability, risk aversion, work ethic, etc.) by using Fixed Effects (FE) estimation. Since these unmeasured player traits are likely to be correlated with observed predictors of performance (games played, playoff contention, age, etc.), traditionally used Ordinary Least Squares (OLS) and …

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 …

Graduate Theses and Dissertations
Our research interests lie in studying the economic behavior, choices, and actions of individuals given their geographical and Social proximity to others, and analyze the consequences of such decisions to the financial health and survival of households, firms, and the macro economy. Network analysis and spatial econometrics take account of information spill-overs and constraints of behaviors as consequence of the geographical and Social distance between and among individuals. In this research, we apply those techniques to analyze aspects of corporate governance and explanations for the recent housing crisis.
The literature on principle-agent problems has devoted most of its attention to …

We present new evidence from the Euro Survey of the Austrian Central Bank on the level of financial literacy in Romania and analyze how financial literacy is related to household savings. Less than 5% of respondents were able to correctly answer the three “core” financial literacy questions on interest compounding, inflation, and risk diversification, with the risk diversification question posing the greatest difficulties. Twenty percent of respondents are able to answer both the interest compounding and inflation questions correctly. Financial literacy levels differ between regions and across rural and urban areas. Older and less-educated individuals perform worst on the financial …

Financial Literacy And Financial Planning In France, Luc Arrondel, Majdi Debbich, Frédérique Savignac
Numeracy
We study financial literacy in France using the PATER survey and following the Lusardi and Mitchell (2011c) approach. We find that some subpopulations are less financially literate than others: women, young and old people as well as less-educated people are more likely to face difficulties when dealing with fundamental financial concepts such as risk diversification and inflation and interest compounding. We also find some differences in financial knowledge depending on the political opinion of the respondents. Finally we show that these differences in financial knowledge are correlated with differences in the propensity to plan: people who score higher on the …

Financial Literacy And Retirement Planning In Switzerland, Martin Brown, Roman Graf
Numeracy
We use a representative survey covering 1,500 households to document the level of financial literacy in Switzerland and to examine how financial literacy is related to retirement planning. We measure financial literacy with standardized questions that capture knowledge about three basic financial concepts: Compound interest, inflation, and risk diversification. We measure retirement planning by the incidence of a voluntary retirement savings account. Our results show that financial literacy in Switzerland is high by international standards--a result which is compatible with the high ranking of Switzerland on the PISA mathematical scales. Financial literacy is lower among low-income, less-educated, and immigrant, non-native-speaking …
