Semiparametric Single Index Panel Data Models With Interactive Fixed Effects: Theory And Practice, Guohua Feng, Bin Peng, Liangjun Su, Thomas Tao Yang
Research Collection School Of Economics
In this paper, we propose a single-index panel data model with unobserved multiple interactive fixed effects. This model has the advantages of being flexible and of being able to allow for common shocks and their heterogeneous impacts on cross sections, thus making it suitable for the investigation of many economic issues. We derive asymptotic theories for both the case where the link function is integrable and the case where the link function is non-integrable. Our Monte Carlo simulations show that our methodology works well for large N and T cases. In our empirical application, we illustrate our model by analyzing …

Identifying Latent Structures In Panel Data, Liangjun Su, Zhentao Shi, Peter C. B. Phillips
Research Collection School Of Economics
This paper provides a novel mechanism for identifying and estimating latent group structures in panel data using penalized techniques. We consider both linear and nonlinear models where the regression coefficients are heterogeneous across groups but homogeneous within a group and the group membership is unknown. Two approaches are consideredpenalized profile likelihood (PPL) estimation for the general nonlinear models without endogenous regressors, and penalized GMM (PGMM) estimation for linear models with endogeneity. In both cases, we develop a new variant of Lasso called classifier-Lasso (C-Lasso) that serves to shrink individual coefficients to the unknown group-specific coefficients. C-Lasso achieves simultaneous classification and …

Shrinkage Estimation Of Covariance Matrix For Portfolio Choice With High Frequency Data, Cheng Liu, Ningning Xia, Jun Yu
Research Collection School Of Economics
This paper examines the usefulness of high frequency data in estimating the covariancematrix for portfolio choice when the portfolio size is large. A computationally convenientnonlinear shrinkage estimator for the integrated covariance (ICV) matrix of financial as-sets is developed in two steps. The eigenvectors of the ICV are first constructed from adesigned time variation adjusted realized covariance matrix of noise-free log-returns of rel-atively low frequency data. Then the regularized eigenvalues of the ICV are estimated byquasi-maximum likelihood based on high frequency data. The estimator is always positivedefinite and its inverse is the estimator of the inverse of ICV. It minimizes the …

Bias Correction And Refined Inferences For Fixed Effects Spatial Panel Data Models, Zhenlin Yang, Jihai Yu, Shew Fan Liu
Research Collection School Of Economics
This paper first presents simple methods for conducting up to third-order bias and variance corrections for the quasi maximum likelihood (QML) estimators of the spatial parameter(s) in the fixed effects spatial panel data (FE-SPD) models. Then, it shows how the bias and variance corrections lead to refined t-ratios for spatial effects and for covariate effects. The implementation of these corrections depends on the proposed bootstrap methods of which validity is established. Monte Carlo results reveal that (i) the QML estimators of the spatial parameters can be quite biased, (ii) a second-order bias correction effectively removes the bias, and (iii) the …

Homogeneity Pursuit In Panel Data Models: Theory And Applications, Wuyi Wang, Peter C. B. Phillips, Liangjun Su
Research Collection School Of Economics
This paper studies estimation of a panel data model with latent structures where individuals can be classified into different groups where slope parameters are homogeneous within the same group but heterogeneous across groups. To identify the unknown group structure of vector parameters, we design an algorithm called Panel-CARDS which is a systematic extension of the CARDS procedure proposed by Ke, Fan, and Wu (2015) in a cross section framework. The extension addresses the problem of comparing vector coefficients in a panel model for homogeneity and introduces a new concept of controlled classification of multidimensional quantities called the segmentation net. We …

The Pros And Cons Of Workplace Tournaments, Roman M. Sheremeta
ESI Working Papers
Tournaments are commonly used in the workplace to determine promotion, assign bonuses, and motivate personal development. Tournament-based contracts can be very effective in eliciting high effort, often outperforming other compensation contracts, but they can also have negative consequences for both managers and workers. The benefits and disadvantages of workplace tournaments have been identified in theoretical, empirical, and experimental research over the past several decades. Based on these findings, I provide suggestions and guidelines for when it might be beneficial to use tournaments in the workplace.

The Effects Of Borrowing Rates On Intra-Firm Disequilibria Between Equity Prices And Cds Premiums – Evidence From Dynamic Panel Analysis., Robert J. Brown
Undergraduate Economic Review
Cointegration techniques are used to estimate the long run equilibrium relationship between a firm’s CDS premium and its equity price, for a panel of large-cap US firms. From these results, the estimated disequilibrium in daily CDS premiums, with respect to equity prices, is constructed. Dynamic panel methods are employed to show the importance of lagged changes in libor rates as determinants of the estimated disequilibrium. Evidence is found that the extent to which the markets deviate from equilibrium will increase as one-month libor rates rise, but, counter-intuitively, will decrease (return towards equilibrium) as longer term libor rates rise.

Robust Forecast Comparison,

Robust Forecast Comparison, Sainan Jin, Valentina Corradi, Norman R. Swanson
Research Collection School Of Economics
Forecast accuracy is typically measured in terms of a given loss function. However, as a consequence of the use of misspecified models in multiple model comparisons, relative forecast rankings are loss function dependent. In order to address this issue, a novel criterion for forecast evaluation that utilizes the entire distribution of forecast errors is introduced. In particular, we introduce the concepts of general-loss (GL) forecast superiority and convex-loss (CL) forecast superiority; and we develop tests for GL (CL) superiority that are based on an out-of-sample generalization of the tests introduced by Linton, Maasoumi, and Whang (2005, Review of Economic Studies …

Estimating The Volatility Occupation Time Via Regularized Laplace Inversion, Jia Li, Viktor Todorov, Tauchen
Research Collection School Of Economics
We propose a consistent functional estimator for the occupation time of the spot variance of an asset price observed at discrete times on a finite interval with the mesh of the observation grid shrinking to zero. The asset price is modeled nonparametrically as a continuous-time Itô semimartingale with nonvanishing diffusion coefficient. The estimation procedure contains two steps. In the first step we estimate the Laplace transform of the volatility occupation time and, in the second step, we conduct a regularized Laplace inversion. Monte Carlo evidence suggests that the proposed estimator has good small-sample performance and in particular it is far …

A Practical Test For Strict Exogeneity In Linear Panel Data Models With Fixed Effects, Liangjun Su, Yonghui Zhang, Jie Wei
Research Collection School Of Economics
This paper provides a practical test for strict exogeneity in linear panel data models with fixed effects when the number of individuals N goes to infinity while the number of time periods T is fixed. The test is based on the supremum of a sequence of Wald test statistics. Under suitable conditions, we establish the asymptotic distribution of the test statistic and consistency of the test. A bootstrap procedure is proposed to improve the finite sample performance and the validity of the procedure is justified. We investigate the finite sample performance of the test via a small set of Monte …

On The Robustness Of Higher Order Risk Preferences, Cary Deck, Harris Schlesinger
ESI Working Papers
Economists have begun to recognize the role that higher order risk preferences play in a variety of settings. As such, several experiments have documented the degree of prudence, temperance, and to a lesser extent, edginess and bentness that laboratory subjects exhibit. More recently, researchers have argued that higher order risk preferences generally conform to mixed risk averse and mixed risk loving patterns that arise from a preference for disaggregating or aggregating harms, respectively. This paper examines the robustness of this pattern in three ways. First, it attempts to directly replicate previous results with compound lotteries over monetary outcomes. Second, it …

Dual Process Utility Theory: A Model Of Decisions Under Risk And Over Time, Mark Schneider
ESI Working Papers
The Discounted Expected Utility model has been a major workhorse for analyzing individual behavior for over half a century. However, it cannot account for evidence that risk interacts with time preference, that time interacts with risk preference, that many people are averse to timing risk and do not discount the future exponentially, that discounting depends on the magnitude of outcomes, that risk preferences are not time preferences, and that risk and time preferences are correlated with cognitive ability. Here we address these issues in a decision model based on the interaction of an affective and a reflective valuation process. The …

Multi-Battle Contests: An Experimental Study, Shakun D. Mago, Roman M. Sheremeta
ESI Working Papers
We examine behavior of subjects in simultaneous and sequential multi-battle contests, where each individual battle is modeled as an all-pay auction with complete information. In simultaneous best-of-three contests, subjects are predicted to make positive bids in all three battles, but we find that subjects often make positive bids in only two battles. In sequential contests, theory predicts sizable bids in the first battle and no bids in the subsequent battles. Contrary to this prediction, subjects significantly underbid in the first battle and overbid in subsequent battles. Consequently, instead of always ending in the second battle, contests often proceeds to the …

Impulsive Behavior In Competition: Testing Theories Of Overbidding In Rent-Seeking Contests, Roman M. Sheremeta
ESI Working Papers
Researchers have proposed various theories to explain overbidding in rent-seeking contents, including mistakes, systematic biases, the utility of winning, and relative payoff maximization. Through an eight-part experiment, we test and find significant support for the existing theories. Also, we discover some new explanations based on cognitive ability and impulsive behavior. Out of all explanations examined, we find that impulsivity is the most important factor explaining overbidding in contests.

Asset Pricing With Financial Bubble Risk, Ji Hyung Lee, Peter C. B. Phillips
Research Collection School Of Economics
This paper characterizes systematic risk stemming from the possible occurrence of price bubbles and measures the impact of this additional risk factor on asset prices. Historical stock market behavior and recent empirical experience have led economists and policy makers to acknowledge that price bubbles in financial markets do occur and need to be accounted for in risk analysis. New econometric tools for analyzing mildly explosive behavior (Phillips and Magdalinos, 2007; Phillips et al., 2011) have made it possible to detect the presence of bubbles in data and to date stamp their origination and collapse, providing empirical confirmation of such episodes …

Modeling Speculative Bubbles With Diverse Investor Expectations, Peter C. B. Phillips
Research Collection School Of Economics
We construct a model of asset market exuberance, collapse and recovery using subjective investor-based rational expectations about the impact of fundamentals on the market price. Investors are assumed to have heterogeneous market sentiments, allowing them to be exuberant, cautious, or fundamentalist via boundary conditions that describe their respective views of the market impact of the same economic fundamentals. Equilibrium solution paths of the model take varying forms, depending on the parameter settings that reflect the importance of each type of market participant. This rational expectations model of asset pricing is shown to be consistent with a simple explosive continuous time …

Residential Electricity Demand In El Paso: 1977-2014, Thomas M. Fullerton Jr., David R. Macias, Adam G. Walke
Border Region Modeling Project
This study analyzes the demand for residential electricity in El Paso, Texas, USA. Annual data are provided by El Paso Electric Company covering the period from 1977 to 2014. This study reports a negative long-run income elasticity for residential electricity demand. Per customer residential electricity usage declines by 0.68 percent for every 1-percent increase in real per capita income over the long run, indicating that electricity is treated as an inferior good by households in this metropolitan economy. That result runs counter to many earlier studies, but corroborates recent empirical evidence for Seattle, Washington and other regions of the United …
