Consumption, Risk And Prioritarianism, Matthew D. Adler, Nicolas Treich
Faculty Scholarship
In this paper, we study consumption decisions under risk assuming a prioritarian social welfare function, namely a concave transformation of individual utility functions. Under standard assumptions, there is always more current consumption under ex ante prioritarianism than under utilitarianism. Thus, a concern for equity (in the ex ante prioritarian sense) means less concern for the risky future. In contrast, there is usually less current consumption under ex post prioritarianism than under utilitarianism. We discuss the robustness of these results to learning, and to other forms of prioritarian social welfare functions.

New Operations Over Interval Valued Intuitionistic Hesitant Fuzzy Set, Florentin Smarandache, Said Broumi
Branch Mathematics and Statistics Faculty and Staff Publications
Hesitancy is the most common problem in decision making, for which hesitant fuzzy set can be considered as a useful tool allowing several possible degrees of membership of an element to a set. Recently, another suitable means were defined by Zhiming Zhang [1], called interval valued intuitionistic hesitant fuzzy sets, dealing with uncertainty and vagueness, and which is more powerful than the hesitant fuzzy sets. In this paper, four new operations are introduced on interval-valued intuitionistic hesitant fuzzy sets and several important properties are also studied.

The Undergrad's Dilemma: N-Person Games And Information Asymmetry In Undergraduate Course Selection, Michael A. Verlezza
Honors Program Theses and Projects
In 2012, the White House released its College Scorecards for institutions of higher education. In their overview, the White House states that Bridgewater State University in Bridgewater, MA, has a six-year graduation rate of just 51.7 percent. By approaching the question of low graduation rates as a consequence of economic inefficiency, my research led me to treat undergraduate course selection as a Nash n-person game. From there, my investigation led to an analysis of information asymmetry as I attempted to identify the various internal and external information sources driving course selection. Specific attention was given to Bridgewater State’s internal system, …
Short-Term Inflation Forecasting Models For Nigeria,

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
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 …

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 …

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 …
