The cointegration test result revealed that the variables had long run relationships. The cointegrating regression result indicated that broad …

The Role Of Agriculture In The Economic Diversification Of The Nigerian Economy: (1980 – 2016), Adamu Hassan Muhammad, Tahir Hussaini Mairiga, Iliya Ayuba Thompson, Usman Ismaeel Bello

Bullion

This study empirically examines the role of agriculture in the diversification of the Nigerian economy, using time series data from 1980–2016. Estimation results using Cointegration and Vector Error Correction Technique indicate that agricultural output has a positive relationship and significant impact with non-oil exports (NOE) and that non-oil revenue has a positive relationship with non-oil exports (NOE). It was recommended that, government should endeavor to increase agricultural productivity by improving its expenditure on the sector so as to enhance the growth of the economy. Government should also increase its non-oil revenue and revive the sector through sufficient budgetary allocation and …

Impact Of Monetary Policy On Inflation Rate In Nigeria: Vector Autoregressive Analysis, Eggon Ahmed Henry, Ajidani Moses Sabo

Bullion

The Nigerian monetary authorities have implemented several monetary management policies with the aim of achieving price stability and economic growth in the country, but without success. This study was conducted to examine the impact of monetary policy management on inflation in Nigeria during the 1985- 2019. Autoregressive distributed lag analysis was employed on time series data covering the period. It was found that while monetary policy rate and foreign exchange rate impacted negatively on inflation; broad money supply impact positively on it. Therefore, the study recommended that monetary authorities should fix the exchange rate at where the value of Naira …

Gender Differences In The Mental Health Of Parents During The Covid-19 Pandemic, Lucia Regina Gomes

Economics

The global COVID-19 pandemic has impacted the mental health of many in the world. With stay-at-home orders and schools transitioning to remote learning, the mental health of parents specifically has become an important topic for research. This paper utilizes Ordinary Least Squares Regression to examine the effect of gender on depleted mental health among U.S. parents. The results indicate an association between mothers and worsened mental health during the onset of the pandemic in the U.S.

The Political Economy Of Small Medium Enterprise Development: Characteristics, Productive Value, And Market Constraints In Industrial Manufacturing, Christine Ngo, Miao Chi

Faculty Journal Articles

This paper highlights the importance of small and medium-sized enterprise (SME) development and introduces the theoretical concept of productive value for qualitative analysis of firms. Vietnam’s industrial development experience is used as a case study. Although the Vietnamese government has channelled rents and business opportunities towards the state sector, the domestic private sector has been crucial to the country’s industrial development. Given this context, this study analyses how Vietnamese SMEs in the private sector generate productive value and overcome market failures that constrain their growth. Research findings demonstrate that most local SMEs in the industrial sectors rely on low pricing …

The Drug Overdose Epidemic Seen Through Different Lenses, Barbara Blake Gonzalez, Richard Cebula, James V. Koch

Economics Faculty Publications

The age-adjusted death rate from drug overdoses in the United States per 100,000 individuals rose from 6.8 in 2010 to 17.1 in 2018. The most common explanation offered is the deaths of despair hypothesis. We identify additional factors that have contributed to the rise in drug overdose deaths in cities and counties. Methods: We utilize a period fixed effects model with a multi-variate panel data set for 94 independent cities and counties in Virginia for the period 2008 through 2017. Results: The drug overdose mortality rate is: (a) an increasing function (prob.

Effect Of Monetary Policy On The Nigerian Stock Market: A Smooth Transition Autoregressive Approach, Babaginda Jamilu S., Khan Asad-Ul I.

CBN Journal of Applied Statistics (JAS)

This paper examines the nonlinear effect of monetary policy decisions on the performance of the Nigerian Stock Exchange market, by employing the Smooth Transition Autoregressive (STAR) model on monthly data from 2013 M4 to 2019 M12 for the All Share Index and monetary policy instrument. This study considers the two regimes characterizing the stock market, which are the lower regime (the bear market) and the upper regime (the bull market). The results show evidence of nonlinear effect of monetary policy on the stock exchange market. Monetary policy rate, money supply, lagged monetary policy rate and lagged treasury bill rate are …

Markovian Approach To Stock Price Modelling In The Nigerian Oil And Gas Sector, Ayo Adekunle S., Uwabor Eboigbe S.

CBN Journal of Applied Statistics (JAS)

The study investigates the stock price movement of quoted Nigerian oil and gas firms using the Markovian model. Specifically, the study estimates the change in likelihoods and steady-state distribution of the share prices of the firms to determine the average time spent by the share price to move to another state and the turnover rate of the selected stocks. Markov chain-based stochastic modelling approach was employed by using the daily closing share prices of all the seven oil and gas firms quoted on the Nigerian Stock Exchange from April 2017 to January 2020. The study finds that the transition probabilities …

Purchasing Power Parity Approach To Exchange Rate Misalignment In Nigeria, Nakorji Musa, Agboegbulem Ngozi T. I., Gaiya Blessing A., Atoi Ngozi V.

CBN Journal of Applied Statistics (JAS)

This study examines the purchasing power parity (PPP) approach to the determination of exchange rate misalignment in Nigeria by using two variants of the PPP: the absolute PPP (aPPP) and the relative PPP (rPPP). Data on the Nigerian Naira to US Dollar (N/$), British Pound (N/£) and Chinese Yuan (N/¥) interbank exchange rates, Nigeria consumer price index and Inflation as well as the US, UK and China consumer price indices and inflation rates spanning 2008:M1 to 2018:M12 were utilized. A recently modified fractional cointegration framework was employed, taking care of smooth structural breaks and nonlinearity, while the unit root tests …

The key findings of the study are that capital expenditure has positive and significant impact on economic growth both in the short run and long run while recurrent expenditure does not have significant impact on economic growth both in the short run and long run. The study …

The Relationship Between The Earning Of Career And Technical Industry Credentials And The Virginia Economy, Anjanette Mcfadden Hendricks

Educational Leadership & Workforce Development Theses & Dissertations

Nationally, the labor market is calling out for workers to fill the increasing number of job vacancies, but those qualified, skilled, and able to fill them are limited in supply or retiring in large numbers. As America’s key industries offer high salaries in return for candidates with the necessary skills and credentials to fill their vacancies, the skills learned and third-party industry credentials earned in secondary Career and Technical Education (CTE) programs seem to make a perfect fit for the student, employer, and the economy. However, unlike the favored US educational model of the four-year degree, the continued outdated perception …

Selling To Reference-Dependent Consumers, Hin Shing Leung

Lingnan Theses (MPhil & PhD)

This research studies the optimal price charged by a monopoly firm when it is facing reference-dependent consumers (Kőszegi and Rabin, 2006). In the model, a consumer’s total utility from purchasing a good consists of intrinsic utility and gainloss utility, the latter of which is determined by an exogenously determined reference point. The firm’s optimal pricing depends on the level of the reference point. In particular, the firm optimally adopts a gain-type pricing strategy when the reference point is low. In this equilibrium, all consumers who purchase enjoy gain utility (gaintype consumers). When the reference point is high the firm optimally …

Three Essays On International Financial And Monetary Interactions, Kemal Burak Bekircan

Dissertations

This dissertation develops three essays on safe haven currency behavior and international monetary interactions.

Essay one notes the dramatic appreciation of the U.S. dollar vis-à-vis all world currencies, along with its reversal after a year on the account of the Great Recession. This paper investigates bilateral U.S. dollar exchange rate movements during and in the aftermath of the Great Recession. I find that increasing global market uncertainty has a significant and consistent effect in strengthening of the U.S. dollar. This striking finding suggests flight-to-safety phenomenon of foreign investors, and repatriation of capital flows to the United States by the U.S. …

Urbanization Policy And Economic Development: A Quantitative Analysis Of China's Differential Hukou Reforms, Wen-Tai Hsu, Lin Ma

Research Collection School Of Economics

The household registration system (hukou system) in China has hampered rural-urban migration by posing large migration friction. The system has been gradually relaxed in the past few decades, but the reforms have been differential in city size and by the coastal-inland divide. We find a striking contrast in the migration patterns between years 2005 and 2015; rural people tended to move more to the coastal urban region in 2005, but more to the inland urban region in 2015. We calibrate a spatial quantitative model to the world economy in both years with China being divided into the rural, coastal urban, …

Point Optimal Testing With Roots That Are Functionally Local To Unity, Anna Bykhovskaya, Peter C. B. Phillips

Research Collection School Of Economics

Limit theory for regressions involving local to unit roots (LURs) is now used extensively in time series econometric work, establishing power properties for unit root and cointegration tests, assisting the construction of uniform confidence intervals for autoregressive coefficients, and enabling the development of methods robust to departures from unit roots. The present paper shows how to generalize LUR asymptotics to cases where the localized departure from unity is a time varying function rather than a constant. Such a functional local unit root (FLUR) model has much greater generality and encompasses many cases of additional interest that appear in practical work, …

Trading Regularity And Fund Performance: Evidence In Uncertain Markets, Lin Tong, Zhe Zhang

Research Collection Lee Kong Chian School Of Business

High trading regularity funds outperform low trading regularity funds more during periods of low market returns and greater market and economic uncertainty. Their trading also has strong return predictability on stock returns during periods of greater uncertainty. They trade more around news events, and their news related trading predicts stock return stronger during periods of greater uncertainty. They also profit from liquidity provision in highly uncertain market environment. Overall our evidence suggests that high trading regularity funds trade more frequently during periods of high uncertainty when information production and processing skill is more valuable and when the demand for liquidity …

Asymptotic Properties Of Least Squares Estimator In Local To Unity Processes With Fractional Gaussian Noises, Xiaohu Wang, Weilin Xiao, Jun Yu

Research Collection School Of Economics

This paper derives asymptotic properties of the least squares estimator of the autoregressive parameter in local to unity processes with errors being fractional Gaussian noises with the Hurst parameter H. It is shown that the estimator is consistent when H ∈ (0, 1). Moreover, the rate of convergence is n when H ∈ [0.5, 1). The rate of convergence is n^2H when H ∈ (0, 0.5). Furthermore, the limit distribution of the centered least squares estimator depends on H. When H = 0.5, the limit distribution is the same as that obtained in Phillips (1987a) for the local to …

On Strategy-Proofness And The Salience Of Single-Peakedness In A Private Goods Economy, Shurojit Chatterji, Masso Jordi, Serizawa Shigehiro

Research Collection School Of Economics

We consider strategy-proof rules operating on a rich domain of preference profiles in a set up where multiple private goods have to be assigned to a set of agents with entitlements where preferences display satiation. We show that if the rule is in addition "desirable", in that it is tops-only, continuous, same-sided and individually rational with respect to the entitlements, then the preferences in the domain have to satisfy a variant of single-peakedness (referred to as smilattice single-peakedness). We also provide a converse of this main finding. It turns our that this domain coincides with the one already identified in …

Quasi-Bayesian Inference For Production Frontiers, Xiaobin Liu, Thomas Tao Yang, Yichong Zhang

Research Collection School Of Economics

We propose a quasi-Bayesian method to conduct inference for the production frontier. This approach combines multiple first-stage extreme quantile estimates by the quasi-Bayesian method to produce the point estimate and confidence interval for the production frontier. We show the asymptotic properties of the proposed estimator and the validity of the inference procedure. The finite sample performance of our method is illustrated through simulations and an empirical application.

Decomposing Duration Dependence: Skill Depreciation Vs. Statistical Discrimination, Ismail Baydur, Jianhuan Xu

Research Collection School Of Economics

This paper develops a random matching model with unobserved worker heterogeneity and learning about worker types from unemployment duration. The model features negative duration dependence that stems from unobserved heterogeneity as well as statistical discrimination and skill depreciation. We estimate our model using micro-level data from Current Population Survey (CPS) and we decompose the contribution of each channel to job finding rates by duration. We find that shutting down statistical discrimination substantially increases the job finding rates of the long-term unemployed while skill depreciation mainly affects the medium-term unemployed.

Firm Productivity And The Variety Of Inputs And Outputs: Evidence From Chinese Trade Data, Ken Onishi, Jianhuan Xu, Guang Yang

Research Collection School Of Economics

This paper studies how the trade liberalization in China changes the firm productivity. We develop a framework to estimate revenue productivity (TFPR) and real productivity (TFPQ) with multi-product firms. We find that the aggregate TFPR increases 30\% from 2002-2007 and TFPQ increases 22\%, suggesting that the observed TFPR increase is mainly driven by real productivity change rather than the markup change. We further decompose the change of productivity into three channels: (1) access to foreign inputs; (2) technology upgrade; (3) resource re-allocation within the firm. We find the most significant channel is the last one, which explains half of the …

Density Of Demand And The Consumer Benefit From Uber, Matthew H. Shapiro

Research Collection School Of Economics

Uber has attracted the attention of economists and policy makers for its innovations in the taxicab market and its potential for significant consumer welfare gains. The size of this gain depends in part on whether these innovations permit transactions previously costly or infeasible. Using New York City — the largest taxi market in the country — as its context, this paper estimates the level of any technological advantage Uber has over hail taxis in matching to consumers. I combine publicly available transportation data with data scraped from Uber and traffic cameras to estimate a model of the demand for transportation …

Causal Change Detection In Possibly Integrated Systems: Revisiting The Money-Income Relationship, Shuping Shi, Stan Hurn, Peter C. B. Phillips

Research Collection School Of Economics

This paper re-examines changes in the causal link between money and income in the United States over the past half century (1959-2014). Three methods for the data-driven discovery of change points in causal relationships are proposed, all of which can be implemented without prior detrending of the data. These methods are a forward recursive algorithm, a rolling window algorithm, and a recursive evolving algorithm all of which utilize subsample tests of Granger causality within a lagaugmented vector autoregressive framework. The limit distributions for these subsample Wald tests are provided. Bootstrap methods are developed to control family-wise size in the implementation …

The Convergence Of Water, Electricity And Gas Industries: Implications For Ppp Design And Regulation, Sock Yong Phang

Research Collection School Of Economics

In several countries that have privatised their utilities, power and water are separate industries regulated by sector-specific regulators. In a parallel development, desalination has become an important source of water supply in countries where there is a shortage of cheap and clean freshwater. Where the energy source is gas, the use of gas-fired power plants to supply electricity for desalination links the water, electricity and gas industries. We use the case of the financial collapse of an integrated water and power project to illustrate the problems that can arise from such convergence, and to draw lessons for firms, Public-Private Partnerships …

Testing For Structural Changes In Factor Models Via A Nonparametric Regression, Liangjun Su, Xia Wang

Research Collection School Of Economics

We propose a model-free test for structural changes in factor models. The basic idea is to regress the data on commonly estimated factors by local smoothing and compare the fitted values of time-varying factor loadings with those of time-invariant factor loadings estimated via principal component analysis. By construction, the test is designed to be powerful against both smooth structural changes and sudden structural breaks with a possibly unknown number of breaks and unknown break dates in the factor loadings. No restrictions on the form of alternatives or trimming of boundary regions near the beginning or end of the sample period …

Diagnostic Tests For Homoskedasticity In Spatial Cross-Sectional Or Panel Models, Badi K. Baltagi, Alain Pirotte, Zhenlin Yang

Research Collection School Of Economics

We propose an Adjusted Quasi-Score (AQS) method for constructing tests for homoskedasticity in spatial econometric models. We first obtain an AQS function by adjusting the score-type function from the given model to achieve unbiasedness, and then develop an Outer-Product-of-Martingale-Difference (OPMD) estimate of its variance. In standard problems where a genuine (quasi) score vector is available, the AQS-OPMD method leads to finite sample improved tests over the usual methods. More importantly in non-standard problems where a genuine (quasi) score is not available and the usual methods fail, the proposed AQS-OPMD method provides feasible solutions. The AQS tests are formally derived and …
