Culture, Institutions & The Long Divergence, Alberto Bisin, Jared Rubin, Avner Seror, Thierry Verdier

ESI Working Papers

During the medieval and early modern periods the Middle East lost its economic advantage relative to the West. Recent explanations of this historical phenomenon— called the Long Divergence—focus on these regions’ distinct political economy choices regarding religious legitimacy and limited governance. We study these features in a political economy model of the interactions between rulers, secular and clerical elites, and civil society. The model induces a joint evolution of culture and political institutions converging to one of two distinct stationary states: a religious and a secular regime. We then map qualitatively parameters and initial conditions characterizing the West and …

A Simple Measure Of Economic Complexity, Sabiou M. Inoua

ESI Working Papers

Contrary to conventional economic growth theory, which reduces a country’s output to one aggregate variable (GDP), product diversity is central to economic development, as recent, “economic complexity”, research suggests. A country’s product diversity reflects its diversity of knowhow or “capabilities”. Researchers proposed the Economic Complexity Index (ECI) and the country Fitness index to estimate a country’s number of capabilities from international export data; these measures predict economic growth better than conventional variables such as human capital. This paper offers a simpler measure of a country’s knowhow, Log Product Diversity (or LPD, the logarithm of a country’s number of products), which …

Differences In Cognitive Reflection Mediate Gender Differences In Social Preferences, Antonio M. Espín, Valerio Capraro, Brice Corgnet, Simon Gächter, Roberto Hernán-González, Praveen Kujal, Stephen Rassenti

ESI Working Papers

Previous studies have shown that women tend to be more egalitarian and less self-interested than men whereas men tend to be more concerned with social efficiency motives. The roots of such differences, however, remain unknown. Since different cognitive styles have also been associated with different distributional social preferences, we hypothesise that gender differences in social preferences can be partially explained by differences in cognitive styles (i.e., women rely more on intuition whereas men are more reflective). We test this hypothesis meta-analytically using data from seven studies conducted in four countries (USA, Spain, India, and UK; n=6,910) where cognitive reflection and …

Strategically Revealing Intentions In General Lotto Games, Keith Paarporn, Rahul Chandan, Dan Kovenock, Mahnoosh Alizadeh, Jason R. Marden

ESI Working Papers

Strategic decision-making in uncertain and adversarial environments is crucial for the security of modern systems and infrastructures. A salient feature of many optimal decision-making policies is a level of unpredictability, or randomness, which helps to keep an adversary uncertain about the system’s behavior. This paper seeks to explore decision-making policies on the other end of the spectrum – namely, whether there are benefits in revealing one’s strategic intentions to an opponent before engaging in competition.We study these scenarios in a well-studied model of competitive resource allocation problem known as General Lotto games. In the classic formulation, two competing players simultaneously …

The Art Of Concession In General Lotto Games, Rahul Chandan, Keith Paarporn, Dan Kovenock, Mahnoosh Alizadeh, Jason R. Marden

ESI Working Papers

Success in adversarial environments often requires investment into additional resources in order to improve one’s competitive position. But, can intentionally decreasing one’s own competitiveness ever provide strategic benefits in such settings? In this paper, we focus on characterizing the role of “concessions” as a component of strategic decision making. Specifically, we investigate whether a player can gain an advantage by either conceding budgetary resources or conceding valuable prizes to an opponent. While one might na¨ıvely assume that the player cannot, our work demonstrates that – perhaps surprisingly – concessions do offer strategic benefits when made correctly. In the context of …

House Prices And Affordability, R. Greenaway-Mcgrevy, Peter C. B. Phillips

Research Collection School Of Economics

The decade following the global financial crisis (GFC) has witnessed rampant house price appreciation in many cities of the developed world. The metropolitan centres of New Zealand showcase this phenomenon with house price appreciation persistently outpacing income growth. In Auckland, the ratio of prevailing median house prices to median household income rose from 6.4 in 2010 to 10.0 in 2016 (Demographia, Citation2011, Citation2017), before declining to 8.6 by 2019 as house prices flat-lined while household incomes increased (Demographia, Citation2020). However, a strong resurgence in house prices during 2020 means that this ratio has resumed its upward trajectory, with an increase …

Joint Tests For Dynamic And Spatial Effects In Short Dynamic Panel Data Models With Fixed Effects And Heteroskedasticity, Zhenlin Yang

Research Collection School Of Economics

Simple and reliable tests are proposed for testing the existence of dynamic and/or spatial effects in fixed-effects panel data models with small T and possibly heteroskedastic errors. The tests are constructed based on the adjusted quasi scores (AQS), which correct the conditional quasi scores given the initial differences to account for the effect of initial values. To improve the finite sample performance, standardized AQS tests are also derived, which are shown to have much improved finite sample properties. All the proposed tests are robust against nonnormality, but some are not robust against cross-sectional heteroskedasticity (CH). A different type of adjustments …

Do Conditional Cash Transfers Increase School Enrollment? Evidence From Brazil, Jeanette L. Silvernale

Master's Theses

Conditional cash transfer programs have been widely deployed across the globe. They seek to bolster human capital by providing benefits contingent upon a variety of actions such as school attendance and regular health checkups. Bolsa Familia is the most extensive conditional cash transfer program, serving 46 million Brazilian citizens. Despite its expansive size, there have been seldom large-scale micro evaluations of the program. Limited data has resulted in small sample sizes drawn from a single point in time. Our study diverges from the rest and utilizes a novel administrative dataset with an overall sample of nearly 60 million and a …

The Conservatism Principle And Asymmetric Preferences Over Reporting Errors, Jivas Chakravarthy, Timothy W. Shields

ESI Working Papers

At present, accounting conservatism is generally viewed from a measurement or reporting perspective. In contrast, we consider whether it relates to a moral rule of conduct. Conservatism has been described as deriving from a preference for reporting errors to be in the direction of understatement rather than overstatement. We experimentally pair Reporters who provide information with Users who rely on the information. We posit that under misaligned incentives that motivate aggressive reporting, Users view an aggressive report as reflecting Reporters’ exploitative intent and expect that a social norm prohibiting aggressive reporting applies. We predict that Users use noisy reporting errors …

Social Determinants Of Health: The Impact On Health Outcomes And Hospital Profitability, Danielle Mcpherson

Doctor of Business Administration Dissertations

Hospitals are experiencing decreasing profitability due to increasing healthcare cost. In this paper, I demonstrate that there is financial value to hospitals by addressing social determinants of health (SDOH) as this strategy improves health outcomes and yields cost savings. I estimate the impact of SDOH on the health outcomes using an IV probit regression analysis and estimated the impact of health outcomes on cost using a basic linear regression. I estimate that improving SDOH by one standard deviation will result in hospital cost savings as follows: addressing Violent Crime will decrease hospital cost between 0.16% and 0.21%, addressing Supplemental Nutrition …

A Capital Asset Pricing Model With Idiosyncratic Risk And The Sources Of The Beta Anomaly, Mark Schneider, Manuel A. Nunez

ESI Working Papers

We introduce a generalization of the classical capital asset pricing model in which market uncertainty, market sentiment, and forms of idiosyncratic volatility and idiosyncratic skewness are priced in equilibrium. We derive two versions of the model, one based on a representative agent who cares about three criteria (risk, robustness, and expected returns), and the other with a microfoundation based on three types of investors (speculators, hedgers, and arbitrageurs). We apply the resulting capital asset pricing model with idiosyncratic risk (IR-CAPM) to provide a new theoretical account of the beta anomaly, one of the most fundamental and widely studied empirical limitations …

Financial Reporting And Moral Sentiments, Radhika Lunawat, Timothy W. Shields, Gregory B. Waymire

ESI Working Papers

Dating back at least to Adam Smith (1790), philosophers and researchers expect that people will behave differently when they know their actions are observable to others. We hypothesize that financial reporting reveals managers’ actions and leads them to take different actions that are better aligned with investor interests. We posit that the reason why is the activation of our internal mental self-evaluation that Smith refers to as an “Impartial Spectator.” We test this hypothesis with an experiment in which we manipulate the availability of a financial report that makes managerial actions transparent. Our evidence shows that financial reporting leads a …

The Chow Test With Time Series-Cross Section Data, James K. Binkley, Jeffrey Young

Faculty & Staff Research and Creative Activity

The Chow test is a standard method to test for differences in regression response across groups. In some cases, the groups being tested are composed of a time series of cross sections. If the individual units within the groups have systematic differences, the Chow test is compromised: individual and group effects become confounded. This can cause rejections in the absence of the group effect of interest. We illustrate the problem with Monte Carlo analyses, and propose an alternative bootstrap-like testing procedure that helps eliminate excessive Type I errors.

Relationship Between Volatility In Domestic Oil Production, Oil Price And Exchange Rate In Nigeria: Co-Integration And Granger Causality Tests, Bashir Umar Faruk

Bullion

The paper examines the relationship between volatility in domestic oil production, oil prices, and exchange rate in Nigeria. The study employs monthly time series data, from January 2006 to August 2018. Data for the Nigerian Bonny light oil prices (COP), Domestic Oil Production (DOP) and Exchange Rate (EXC) are obtained from the Central Bank of Nigeria (CBN) website. While, dummy variable (DUM) represents stability and instability in the Niger-Delta oil-rich region was traced from historic oil disruptions in the region. Autoregres s i ve Di s tributed Lag (ARDL)/bound testing method and pairwise granger causality were employed. Unit root test …

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 …

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 …

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 …

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 …

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 …

Analysing User Experience Of Mobile Banking Applications In Nigeria: A Text Mining Approach, Omotosho Babatunde S.

CBN Journal of Applied Statistics (JAS)

This paper analyses textual data mined from 37,460 reviews written by mobile banking application users in Nigeria over the period November 2012 – July 2020. On a scale of 1 to 5 (5 being the best), the average user rating for the twenty-two apps included in our sample is 3.5; with the apps deployed by non-interest banks having the highest average rating of 4.0 and those by commercial banks with national authorisation having the least rating of 3.4. Results from the sentiment analysis reveal that the share of positive sentiment words (17.8%) in the corpus more than double that of …

Money And Foreign Exchange Markets Dynamics In Nigeria: A Multivariate Garch Approach, Atoi Ngozi V., Nwambeke Chinedu G.

CBN Journal of Applied Statistics (JAS)

This study examines the money market and foreign exchange market dynamics in Nigeria by estimating the dynamic correlation and volatility spillovers between the Nigeria Naira/US Dollar Bureau De Change (BDC) exchange rate and interbank call rate with data from January 2007 to August 2019. The study employs a dynamic conditional correlation form of the GARCH model (DCC-GARCH) to assess the nature of correlation, while an unrestricted bivariate BEKK-GARCH (1, 1) form of the multivariate GARCH model is utilized to investigate shocks and volatility spillover of the rates. The estimated DCC-GARCH (1, 1) reveals that interest rate and exchange rate are …

Impact Of Government Expenditure On Economic Growth In Nigeria, 1970-2019, Aluthge Chandana, Jibir Adamu, Abdu Musa

CBN Journal of Applied Statistics (JAS)

This study investigates the impact of Nigerian government expenditure (disaggregated into capital and recurrent) on economic growth using time series data for the period 1970-2019. The paper employs Autoregressive Distributed Lag (ARDL) model. To ensure robustness of results, the study accounts for structural breaks in the unit root test and the co-integration analysis. 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 …

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.

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, …

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 …

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 …

Does Bitcoin Use Affect Crime Rates?, Kevin Keane

The Corinthian

Bitcoin is the most widely used cryptocurrency in the world because of its decentralized network that completes user-to-user transactions, eliminating the need for intermediaries. During 2017, the volume of Bitcoin transactions totaled $94.3 trillion. Bitcoin transactions are recorded in a public database called the blockchain. Although the blockchain can keep track of how many transactions there are, it can’t identify the people involved in transactions. The lack of identity increases the anonymity of Bitcoin transactions, making it less detectable when used for crime. Using the Uniform Crime Reporting’s state-level crime rate data and blockchain’s Bitcoin transaction information, I estimate the …

Market Trends In Food Consumption Expenditures Away From Home Prior To The Covid-19 Pandemic, Rebecca Weir

Undergraduate Economic Review

U.S. food consumption expenditures away from home increased from 19 percent of total food expenditures in 1955 to 48 percent in 2015. Simultaneously, female participation in the labor force grew by 52.7 million women from 35 to 57 percent, signifying increased opportunity cost for women to prepare meals at home. This research uses an ordinary least squares regression to examine socioeconomic factors influencing the rise in U.S. food consumption expenditures away from home in 2018. Results inform food production and service industries’ marketing strategies, and set the stage for whether a new pattern emerges in response to the COVID-19 pandemic.
