Determinants of Technical Efficiency in Chinese Banking: A Double Bootstrap Data Envelopment Analysis Approach

Abstract

The main objective of this study is to measure the technical efficiency level of the Chinese banking industry. It uses a double bootstrap data envelopment analysis approach to compute bias-corrected efficiency scores and investigate the determinants of bank efficiency in China between 2003 and 2010. We observe that Chinese commercial banks regardless of ownership have shown improved efficiency from 2003 to 2010. Our results show a significant difference in the performance between state-owned banks and joint-stock banks over the period analyzed. Moreover, the equity-to-asset ratio also significantly explains variations in inefficiency across Chinese commercial banks. Initial public offering is considered one of the effective ways to improve bank efficiency in China. Overall, the present study provides valuable empirical information that can be used to help guide deliberations regarding future reform policies.     

归并自变量模型估计

在线性回归模型中,如果因变量存在样本归并,普通的LS估计不再一致,Rigobon和Stoker（2004,2007）建议使用部分样本回归或完整形式分析的方法来获得参数的一致估计,但是,它们都不是有效估计。本文使用基于EM算法的ML估计来获得参数的有效估计,在正态混合模型设定下详细推导了观测样本的似然函数以及相应的EM迭代方程。数值模拟的结果表明,基于EM算法的ML估计比部分样本回归和完整形式分析的方法具有更好的小样本表现。     

Managerial Myopia,Earnings Guidance,and Investment*

This study investigates the real effects of management communication, specifically of forecasts or earnings guidance, on investment. Managers can signal the strength of their projects through accuracy in their earnings guidance. This leads less accurate managers to distort their investments; the equilibrium investment strategy involves over-investment when earnings exceed the forecast and under-investment when earnings fall short. Moreover, we find that managers are pessimistic in their forecasts, which helps to explain the corresponding well-documented empirical regularity. This downward bias increases the likelihood of investment manipulation but decreases the real loss from distortion. Interestingly, the over-investment induced by earnings guidance helps to mitigate the classic under-investment problem for a myopic manager with unobservable investment. Earnings guidance can therefore be value-increasing when managerial myopia is severe.     

Real Exchange Rate Dynamics in the Asian Economies: Can Regime Shifts Explain Purchasing Power Parity Puzzles?

Abstract

We show that the strong version of the purchasing power parity (PPP) hypothesis holds in most of the US dollar real exchange rates using cointegration method that accounts for breaks in the models. The break dates in seven of the Asian currencies coincide with the two rounds of currency depreciation recorded during the 1997–1998 financial crises. We obtain a mean half-life estimate of about 10 months for PPP to converge to its long-run equilibrium level. Our confidence intervals based on persistence profile approach for the half-lives is much narrower than previous evidence might indicate. Taken together, these results show that mean reversion is stronger than commonly thought.     

Re-examining the Fisher Effect: An Application of Small Sample Distributions of the Covariate Unit Root Test

Abstract

This article employs the covariate unit root test proposed by Elliott and Jansson to investigate the stationarity properties of real interest rates. Instead of blindly trusting the asymptotic distribution of the test, we extend Rudebusch's method to estimate its finite sample distributions under the null and alternative hypotheses. With these distributions, we can obtain the probabilities that the test statistic comes from the null and alternative hypotheses, and quantify the asymptotic size as well as the test power for each specific series. Our simulation experiments show that first, due to the higher power raised by the inclusion of covariates, the test can overwhelmingly reject the unit root null for the 16 industrialized countries; secondly, the Ng and Perron tests deliver lower powers in most countries, and thus lead to the false conclusion of non-stationary real interest rates. Finally, allowing for multiple endogenous breaks in the real interest rates provides only stationary evidence in half of the 16 countries.     

Bayesian Analysis of Entry Games: A Simulated Likelihood Approach Without Simulation Errors

Abstract

This paper provides a practical guide to Bayesian estimation of simultaneous entry games of complete information with heterogeneous firms. Bayesian inference requires computation of the likelihood, which is carried out by simulating unobservables. To avoid errors from finite simulations, we apply Andrieu and Roberts’s [2009. The pseudo-marginal approach for efficient Monte Carlo computations, Annals of Statistics, 37(2), pp. 697–725] pseudo-marginal approach. We rely also on adaptive Markov chain Monte Carlo algorithms that improve computational performance.     

The Asymmetric Loss Function and the Central Banks’ Ability in Developing Countries

Abstract

This paper seeks to develop a theoretical strand of research in monetary economics by modelling central bank ability in the loss function. Recently, many working papers issued by the International Monetary Fund (IMF) prove that some central banks, particularly from developing countries, are suffering from serious operational problems that might affect their abilities to control the economy. Simultaneously, a literature review shows that the movements are toward using asymmetric loss function. Therefore, we utilize this function in the standard monetary approach. The results proved that both central bank ability and preference in developing countries are fundamental to explain inflation bias and the movement of monetary policy instrument.     

The Effects of Biasing Performance Measurement Systems on Incentives and Retention Decisions

We examine a principal–agent setting in which the principal uses a performance measurement system for multiple purposes—to provide incentives and for retention decisions. The principal chooses the nature and extent of bias in the system, which determines whether the performance report is stringent, neutral, or lenient relative to the unobservable actual outcome. We show that when the report is used only for incentive purposes (an incentive role), stringency alleviates moral hazard. On the other hand, when the principal's objective is to minimize the cost from incorrect retention and firing decisions (a fit evaluation role), there is a demand for leniency. Surprisingly, however, we show that adding a fit evaluation role to a system serving an incentive role can accentuate the demand for stringency because stronger incentives can also indirectly improve retention decisions.     

Firm-level human capital and innovation: Evidence from China

This paper examines the role of human capital in firms' innovation. Based on a World Bank survey of manufacturing firms in China, we use two firm-level datasets: one from large metropolitan cities, and one from mid-sized cities. Patents are used as an indicator of innovation. The human capital indicators we use include the number of highly educated workers, the general manager's education and tenure, and the management team's education and age. We use the Negative Binomial and Instrumental Variables estimators to estimate patent production function models that are augmented by our human capital variables. We also use the zero-inflated Negative Binomial model to examine the likelihood of innovation. We find that the human capital indicators play an important role in influencing patenting, and that some of the human capital variables appear to have a greater impact on patenting in mid-sized cities. Our human capital estimates are obtained after controlling for firms' R&D, size, market share, age, and foreign ownership, as well as fixed effects to control for industry-specific characteristics, and firms' location and geography.     

Business Strategy,Financial Reporting Irregularities,and Audit Effort

This study examines whether clients' business strategies are a factor in determining the occurrence of financial reporting irregularities and the level of audit effort. We use the organizational strategy theory of Miles and Snow to develop a comprehensive measure of business strategy using publicly available data. We find that Miles and Snow's Prospector strategy is more likely to be involved in financial reporting irregularities and generally requires greater audit effort. The business strategy measure also appears to capture client business risk and provides incremental explanatory power beyond the individual measures of client complexity or risk used in traditional audit fee models. We contribute to the literature by constructing a replicable business strategy measure and identifying organizational business strategy as an important ex ante determinant of financial reporting irregularities and levels of audit effort. Our results suggest that investigating how audits can be improved to reduce financial reporting irregularities among Prospector clients is an important area for audit practice and future research.     

Bilateral Trade Balances of Malaysia with Her 11 Largest Trading Partners: New Evidence from Asymmetry Cointegration

Research on the effects of exchange rate changes on the trade balance is now moving in a new direction, by investigating whether exchange rate changes have symmetric or asymmetric effects. The approach that relies upon separating depreciations from appreciations introduces nonlinearity into the adjustment process and relies upon the nonlinear ARDL approach of Shin et al. [2014. Modelling asymmetric cointegration and dynamic multipliers in a nonlinear ARDL framework, in: R. Sickels and W. Horrace (Eds), Festschrift in Honor of Peter Schmidt: Econometric Methods and Applications, 281–314 (Springer)]. When we applied this new method to the bilateral trade balances of Malaysia with each of her 11 largest partners, we found adjustment asymmetry in all models, short-run impact asymmetry effects and long-run asymmetry effects in the trade balance models between Malaysia and Asian countries.     

Exchange Rate Expectations,the Forward Exchange Rate Bias and Risk Premia in Target Zones

Expected rates of depreciation within the target zone for the exchange rates of four Nordic countries during 1979–1989 are estimated. Combining these with expected rates of devaluation estimated by Edin and Vredin (1993) we obtain time-series of the overall expected exchange rate change. We can thus construct time-series of foreign exchange risk premia and expectational errors, following which we decompose the forward exchange rate bias into portions attributable to expectational errors and/or risk premia. The conclusion is that time-varying risk premia appear to be the dominant cause of deviations from uncovered interest parity while the role of expectational errors is less clear.     

The theories of ‘stages of growth’

Abstract

The idea of a ‘virtuous circle’ has always been implied in the theories of ‘stages of growth’, though never systematically demonstrated, We are here concerned with two aspects of these theories: (1) the implied theory of circular causation with cumulative effects; (2) the implicit systematic biases. The biases operate through the selection of strategic factors on which interest is focussed and of assumptions concerning their role in historical processes. This selection of strategic factors and of assumptions about their role remains essentially a priori, however much illustrative material is amassed. It never is—and, in this teleological approach, it never can be—empirically verified or refuted. A fundamental preconception is, moreover, the similarity of evolution in different countries at different historical periods; this is why these theories can be used, and are used, for prediction. But similarity depends on the level of abstraction and the choice of features compared. Such comparisons can be refuted only by demonstrating that other principles of selection and comparison are equally possible—and, of course, ex post, that the predictions do not come true.     

Alcohol Prices,Consumption, and Traffic Fatalities

We examine the relationships among alcohol prices, consumption, and traffic fatalities using data across U.S. states from 1982 to 2000. Some previous studies have found large, negative associations between alcohol taxes and fatalities. However, commonly used price data suggest little or no connection between alcohol prices and fatalities. These apparently conflicting findings may result from measurement error and/or endogeneity in the price data, which biases ordinary least squares estimators toward a finding of no price effects. Using alcohol taxes as instrumental variables, fatalities are found to be negatively related to prices. In addition, alcohol consumption is strongly positively related to fatalities. However, biases may still remain, because taxes are not entirely suitable as instruments.     

CSR in an Asymmetric Duopoly with Environmental Externality

We investigate a linear state differential game describing an asymmetric Cournot duopoly with capacity accumulation á la Ramsey and a negative environmental externality (pollution), in which one of the firms has adopted corporate social responsibility (CSR) in its statute, and therefore includes consumer surplus and the environmental effects of production in its objective function. If the market is sufficiently large, the CSR firm sells more, accumulates more capital, and earns higher profits than its profit‐seeking rival.     

Performance Persistence of Dutch Pension Funds

This paper studies the investment performance of pension funds with a focus on their ability in implementing their intended investment strategy. We use a sample of Dutch industry-wide pension funds, which are obliged by law to report their investment performance according to the so-called z-score. The z-score is a risk-adjusted performance measure with benchmark settings predefined by Dutch law. We find that pension funds as a group cannot beat their self-selected benchmarks consistently. Applying a cross-sectional portfolio approach we find evidence that the largest pension funds outperform the smallest funds.     

A generalized multi-country endogenous growth model

The transitional dynamics of open-economy endogenous growth models are largely unexplored. The present paper fills this gap in the literature. By applying the familiar Travis–Dixit–Norman (Dixit and Norman, Theory of International Trade, Cambridge University Press, Cambridge, UK, 1980) approach to a general class of growth models, it provides original results on the transitional dynamics of the multi-country open-economy versions of several prominent special cases, including the models of Romer (J Polit Econ, 94:1002–1037, 1986; J Polit Econ 98:S71–S102, 1990), Lucas (J Monet Econ, 22:3–42, 1988), Grossman and Helpman (Innovation and Growth in the Global Economy. MIT Press, Cambridge, MA, 1991a, Chaps. 3 and 4; Rev Econ Stud 58:43–61, 1991b), Jones (J Polit Econ, 103:759–784, 1995a), and Segerstrom (Am Econ Rev, 88:1290–1310, 1998). This approach also shows that, in the class of models considered, the question of whether or not international economic integration accelerates growth in the long run is equivalent to the question of whether or not scale effects prevail.      

The Non-equivalence Revisited: Staggered Price and Wage Contracts

Abstract

Staggered wage-setting and price-setting have frequently been used to construct business cycle models that can replicate long-lasting real effects of monetary shocks. We examine how the two seemingly equivalent sources of nominal rigidities compare in generating persistence in real output following monetary expansion. We show that staggered wage-setting is in general better able to generate persistence, because it can lower the procyclicality of marginal cost considerably more than staggered price-setting does.     

Experience,Learning, and Returns to Scale

The experience curve is a tool for forecasting future decreases in average cost as a function of cumulative output/volume. The extent of an experience effect has profound implications for both pricing strategy and the focus on market share as a managerial objective. At the same time, the underlying sources of the experience effect are not well understood. This article demonstrates that, as commonly measured, experience effects are aggregated with the effects of increasing returns to scale. This implies that standard experience curve estimates are misspecified because they suffer from an omitted variable bias. Strategic implications of the experience‐scale link are discussed.
