Do Hitters Boost Their Performance During Their Contract Years?, Heather M. O'Neill

Business and Economics Faculty Publications

Each season, baseball fans and journalists alike identify which players are in the final years of their contracts because a lot rides on how the players produce in their “contract year.” Will a player boost his effort and performance in an effort to improve his value and bargaining power? Or will he crumble under the pressure? Or are players’ performances uncorrelated with where they stand in their contract cycles?

A Backward Bending Supply Of Loanable Funds: An Examination Of The Interest Rate Elasticity Of Saving, Rachel M. Doehr Ms.

Undergraduate Economic Review

The market for loanable funds is presented as either a market with an upward sloping supply curve, or as one with a perfectly inelastic supply. This paper relates the supply of loanable funds to the supply curve in the labor market: backward bending. Once interest rates are high enough, people start to save less, creating the "backward bend.” This explains the discrepancies in previous literature that attempted to put a single value on the interest rate elasticity saving. The reason for the variation in values could be because the elasticity actually depends on the point on the curve.

Experimental Evidence For Heterogeneous Expectations In A Simple New Keynesian Framework, Atticus David Holm Graven

Business and Economics Honors Papers

This paper is a two-dimensional analysis of agent behavior in a standard New Keynesian (NK) Macroeconomic model. On the dimension of pure mathematics, we analyze the parameters of the NK model and of possible prediction rules. On the other dimension we continue a practice of empirical study of heterogeneous expectations with an experiment. The experiment will ask participants to make predictions of future output and inflation. Their responses will create a data-set upon which analysis will be performed to illuminate and corroborate current theories of economic decision making. The literature has shown that most agents' forecasting rules can be modeled …

Coexistence Of Gm, Conventional And Organic Food Not Always Possible, Konstantinos Giannakas

CAFIO: Policy Research Group Policy Pagers

The coexistence of genetically modified (GM) products with their conventional and organic counterparts has been one of the most scrutinized issues surrounding the introduction of products of agricultural biotechnology into the agri-food system. Fears that the widespread adoption of GM products will drive their conventional (and, perhaps, organic) counterparts out of the market have been countered by arguments that their presence enhances the equilibrium product variety in the market. Central to the argument is, of course, the possibility of coexistence of GM, conventional and organic products with the main focus having been on farm production systems and the prospect of …

Gmos And Iprs Are Key Weapons In Fight Against Hunger, Konstantinos Giannakas

CAFIO: Policy Research Group Policy Pagers

The introduction of genetically modified organisms (GMOs) into the food system and the assignment of intellectual property rights (IPRs) for plant genetic resources are among the most notable features of the increasingly industrialized agri-food marketing system of numerous developed and developing countries around the world. IPRs have provided innovating firms with incentives to aggressively pursue improvements of crop characteristics (such as herbicide tolerance, insect and virus resistance, drought tolerance and increased nutritional value) through gene splicing techniques, and the agronomic benefits associated with the genetically modified (GM) products have resulted in their embrace by a significant number of agricultural producers …

Ad Hoc Disaster And Crop Insurance Programs May Reduce The Use Of Risk-Reducing Conservation Tillage Practices, Karina Schoengold, Ya Ying, Russell Headlee

CAFIO: Policy Research Group Policy Pagers

There is growing concern that the risks facing agricultural producers are increasing due to several factors that include the predicted effects of climate change leading to more frequent floods, droughts, and higher temperatures as well greater use of agricultural outputs for nonfood energy products.

These risks are partially managed through federal agricultural programs. Ad hoc disaster payments have frequently been used to provide financial support.

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 …

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.

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 …

Consumer Attitudes And Labeling Regime Key To The Market Potential Of Food Nanotechnology, Miah Tran, Amalia Yiannaka, Konstantinos Giannakas

CAFIO: Policy Research Group Policy Pagers

Research shows that, even though most consumers lack knowledge and understanding of the technology, they nevertheless have strong opinions as to its potential risks and benefits. Advocates are determined to not repeat the mistakes of biotechnology. Understanding the factors determining the market acceptance of food nanotechnology and its potential impact on the different interest groups involved can inform the design of effective policies and strategies governing food nanotechnology innovations.

Country-Of-Origin-Labeling Creates Winners And Losers Among Consumers, Producers, And Retailers, Konstantinos Giannakas, Alejandro Plastina, Daniel Pick

CAFIO: Policy Research Group Policy Pagers

Public Law 107-171, the United States Farm Security and Rural Investment Act of 2002, required country-of-origin labeling (COOL) for beef, lamb, pork, fish, perishable agricultural commodities, and peanuts. While the aim is to benefit domestic consumers by allowing them to make informed decisions, the effects of COOL have been the subject of a heated on-going debate. Advocates of COOL argue the existence of an “overwhelming” consumer support for country of origin information and benefits that substantially outweigh the costs of this labeling regime. Opposing groups have expressed concerns about the potential competitive disadvantage that non-integrated producers might face due to …

Consumer-Oriented Gm Products Can Hurt Producers, Konstantinos Giannakas, Rim Lassoued

CAFIO: Policy Research Group Policy Pagers

Despite their important agronomic benefits to agricultural producers, GM products (GMPs) have been facing a, rather strong, consumer opposition. This opposition varies significantly between countries and so does the countries’ regulatory response to products of biotechnology. While the US treats biotech products as substantially equivalent to their conventional counterparts and does not require their segregation and labeling, the European Union (EU), based on its “precautionary principle” and consumers’ “right to know,” has instituted a mandatory labeling regime that is regarded as the strictest in the world.

Food Labeling Standards Have Significant Welfare And Distributional Impacts, Konstantinos Giannakas, Nicholas Kalaitzandonakes, Alexandre Magnier

CAFIO: Policy Research Group Policy Pagers

Discussions on the appropriate regulatory norms for genetically modified (GM) foods date back to the early 1980s. Thirty years later, a consensus on what such norms should be remains elusive. Some countries, including the United States and Canada, consider GM foods substantially equivalent to their conventional counterparts and do not require segregation and labeling of these products. Others, including the European Union, Japan, South Korea, New Zealand, Australia, and China have introduced mandatory labeling regimes.

Empathy Nudging Increases Conservation Of Farming Land, Natalia V. Czap, Hans J. Czap, Gary D. Lynne, Mark E. Burbach

CAFIO: Policy Research Group Policy Pagers

One of the major challenges of environmental policy with regard to conservation is that it must often rely on voluntary and non-selfish actions of individuals. Traditionally policy makers rely on direct regulation and financial incentives, but both approaches face problems. Regulations may lead to resentment and the costs of perfect enforcement are prohibitively high. Financial incentives can be perverse and may lead to unintended consequences, including crowding out of intrinsic motivation. In addition, behavioral economics and economic psychology studies demonstrate that the assumptions of the neoclassical economic models (such as self-interest only, rationality, and willpower) on which the policy design …

2013 Farm Bill: An Experimental Test Of The Senate And House Proposals, Natalia V. Czap, Hans J. Czap, Gary Lynne, Mark E. Burbach

CAFIO: Policy Research Group Policy Pagers

The 2008 Farm Bill currently guides agricultural and related environmental/conservation policy. Versions proposed by the United States Senate and the House of Representatives, to be implemented in the 2013 Farm Bill after differences are resolved, aim to achieve environmental (and other food related) goals, while also seeking significant spending cuts. While both versions propose to eliminate the Direct Payments program, they differ with respect to how other crop supports should work and whether crop insurance subsidies should be linked to conservation practices. The Senate Bill supports a policy design based on cross‐compliance, that is, crop insurance subsidies are conditional on …

The Role Of Macroeconomic And Group Threat In Prejudice, Aaron Hass

Morehead State Theses and Dissertations

A thesis presented to the faculty of the College of Science and Technology at Morehead State University in partial fulfillment of the requirements for the Degree of Master of Science by Aaron Haas on June 11, 2012.

A Study In Market Micromanagement: The Asymmetrical Effects Of The 2008 Short Sale Ban On Stocks With And Without Traded Options, James W. Weyerhaeuser

CMC Senior Theses

This study provides an empirical analysis of the 2008 short sale ban. The evidence suggests that the presence of tradable options plays a crucial role in determining the effect of a short sale ban. Results show that if there are no traded options on a stock, the short sale ban brought abnormal returns of roughly +8%. However if there are traded options on a stock, the market maker exemptions nullify the positive effects of the ban. Furthermore, for the banned stocks that do experience positive abnormal returns during the ban, the lifting of the ban causes a prompt reversal of …

Contributions Of Financial Sector Reforms And Credit Supply To Nigerian Agricultural Sector (1978-2009), Anthony O. Onoja, M. E. Onu, S. Ajodo-Ohiemi

CBN Journal of Applied Statistics (JAS)

This study analyzed the trends and pattern of institutional credit supply to agriculture during pre- and post-financial reforms along with their determinants. It then compared the effects of reform policies on access to institutional credits in Nigerian agricultural sector before and after the reforms (1978 - 1985; and 1986 -2009). Relying mainly on time series data from CBN and NBS, it used ordinary least squares method (linear, semi-log and double log) to model the determinants of banking sector lending to the agricultural sector during the review period. The models were subjected to several econometric tests before accepting one. Chow test …

Determinants Of Foreign Reserves In Nigeria: An Autoregressive Distributed Lag Approach, David Irefin, Baba N. Yaaba

CBN Journal of Applied Statistics (JAS)

On global scale, central banks’ holdings of foreign reserves have escalated sharply in recent years. World international reserves holdings have risen significantly from US$1.2 trillion in 1995 to nearly US$10.0 trillion in June 2011. Dominant among these reserves are concentrated in the hands of few countries. Ten major holders of foreign reserves are mostly from Asia. Oil exporting countries in Africa and the Middle East are not left out in this trend. Nigeria’s foreign reserves rose from US$5.5 billion in 1999 to US$62.40 billion in July 2008, making Nigeria the twenty-fourth largest reserves holder in the world. This pace of …

Effects Of Exchange Rate Movements On Economic Growth In Nigeria, Eme O. Akpan, Johnson A. Atan

CBN Journal of Applied Statistics (JAS)

This study investigates the effect of exchange rate movements on real output growth in Nigeria. Based on quarterly series for the period 1986 to 2010, the paper examines the possible direct and indirect relationship between exchange rates and GDP growth. The relationship is derived in two ways using a simultaneous equations model within a fully specified (but small) macroeconomic model. A Generalised Method of Moments (GMM) technique was explored. The estimation results suggest that there is no evidence of a strong direct relationship between changes in exchange rate and output growth. Rather, Nigeria’s economic growth has been directly affected by …

Exchange Rate Volatility In Nigeria: Consistency, Persistency & Severity Analyses, Babatunde Adeoye, Akinwande A. Atanda

CBN Journal of Applied Statistics (JAS)

The adoption of the International Monetary Fund (IMF) Structural Adjustment Programme (SAP) in 1986 resulted in the transition from fixed exchange rate regime to floating exchange rate regime in Nigeria. Ever since, the exchange rate of naira vis-à-vis the U.S dollar has attained varying rates all through different time horizons. On this basis, this study examines the consistency, persistency, and severity (degree) of volatility in exchange rate of Nigerian currency (naira) vis-a-vis the United State dollar using monthly time series data from 1986 to 2008. The standard Purchasing Power Parity (PPP) model was used to analyze the long-run consistency of …

Foreign Private Investment And Economic Growth In Nigeria: A Cointegrated Var And Granger Causality Analysis, F. Z. Abdullahi, S. Ladan, Haruna R. Bakari

CBN Journal of Applied Statistics (JAS)

This research uses a cointegration VAR model to study the contemporaneous long-run dynamics of the impact of Foreign Private Investment (FPI), Interest Rate (INR) and Inflation rate (IFR) on Growth Domestic Products (GDP) in Nigeria for the period January 1970 to December 2009. The Unit Root Test suggests that all the variables are integrated of order 1. The VAR model was appropriately identified using AIC information criteria and the VECM model has exactly one cointegration relation. The study further investigates the causal relationship using the Granger causality analysis of VECM which indicates a uni-directional causality relationship between GDP and FDI …

Banking Sector Credit And Economic Growth In Nigeria: An Empirical Investigation, Aniekan O. Akpansung, Sikiru J. Babalola

CBN Journal of Applied Statistics (JAS)

The paper examines the relationship between banking sector credit and economic growth in Nigeria over the period 1970-2008. The causal links between the pairs of variables of interest were established using Granger causality test while a Two-Stage Least Squares (TSLS) estimation technique was used for the regression models. The results of Granger causality test show evidence of unidirectional causal relationship from GDP to private sector credit (PSC) and from industrial production index (IND) to GDP. Estimated regression models indicate that private sector credit impacts positively on economic growth over the period of coverage in this study. However, lending (interest) rate …
