We investigate how different governance arrangements affect risk and return in banks. Using a new data set for UK banks over the period 2003–2012, we employ a simultaneous equations framework to control for the reciprocal relationship between risk and return. We show that separation of the roles of CEO and Chairman increases bank risk without causing a concurrent increase in return. We also find that oversight by a Remuneration Committee and Non-Executive Directors (NEDs) lowers the probability of bank failure, indicating that empowering an independent Chairman has different effects from empowering independent NEDs. Overall, our results underline the importance of accounting for the heterogeneity in corporate governance arrangements within banks. 相似文献

The main purpose of this article is to empirically investigate the interactions between changes in capital buffer and changes in credit risk, using panel data of Islamic and conventional banks located in the Middle East and North Africa (MENA) region over the period 1999–2016. A negative two‐way relationship between the changes in capital buffer and the changes in credit risk is found for the two types of banks, that is, banks tend to decrease their capital buffers in response to an increase in risk exposure and limit their risky activities in response to an increase in their capital buffers. Dividing our period of study into three subperiods to assess the effect of the last financial crisis 2007–08 on the adjustment process, we point out the negative bidirectional relationship between the changes in capital buffer and the changes in credit risk of the two types of banks is present for the three subperiods except the case of conventional banks during the precrisis period. Moreover, we provide evidence that Islamic banks adjust their capital buffer in response to the changes in credit risk regardless of the existence or not of a deposit insurance scheme. In contrast, the negative two‐way relationship between the changes in capital buffer and the changes in credit risk in conventional banks is found only in countries without deposit insurance schemes. 相似文献

This study aims to broaden the current knowledge on the antecedents and consequences of customers’ psychological ownership (CPO) from new perspectives in the hotel context. Specifically, this study investigates how self-image congruity and functional congruity affect CPO through impression in memory based on self-congruity theory and also examines two types of customer engagement—customers’ social influence engagement and knowledge-sharing engagement—as new CPO outcomes. Using survey data collected from 433 Chinese hotel customers, this study finds that self-image congruity positively predicts CPO partially through impression in memory, whereas functional congruity positively influences CPO fully through impression in memory. Moreover, the findings indicate that CPO significantly drives customers’ social influence engagement and knowledge-sharing engagement. This study contributes theoretically to the CPO literature by further developing its linkages with congruity perceptions and customer engagement. Practical implications of the findings can help hotel managers effectively promote CPO and customer engagement. 相似文献

We study forward curves formed from commodity futures prices listed on the Standard and Poor’s-Goldman Sachs Commodities Index (S&P GSCI) using recently developed tools in functional time series analysis. Functional tests for stationarity and serial correlation suggest that log-differenced forward curves may be generally considered as stationary and conditionally heteroscedastic sequences of functions. Several functional methods for forecasting forward curves that more accurately reflect the time to expiry of contracts are developed, and we found that these typically outperformed their multivariate counterparts, with the best among them using the method of predictive factors introduced by Kargin and Onatski (2008). 相似文献

In this paper, we introduce a functional method to investigate how betas change over time in factor models. Based on the China A-share data, we drop the constant beta assumption in the CAPM and multi-factor models to estimate the time-varying betas directly from the functional data regression. The empirical results show that exposures to all risk factors have certain time-varying patterns in the Chinese A-share stock market. 相似文献

The dual risk model assumes that the surplus of a company decreases at a constant rate over time, and grows by means of upward jumps which occur at random times with random sizes. In the present work, we study the dual risk renewal model when the waiting times are phase-type distributed. Using the roots of the fundamental and the generalized Lundberg’s equations, we get expressions for the ruin probability and the Laplace transform of the time of ruin for an arbitrary single gain distribution. Then, we address the calculation of expected discounted future dividends particularly when the individual common gains follow a phase-type distribution. We further show that the optimal dividend barrier does not depend on the initial reserve. As far as the roots of the Lundberg equations and the time of ruin are concerned, we address the existing formulae in the corresponding Sparre-Andersen insurance risk model for the first hitting time, and we generalize them to cover also the situations where we have multiple roots. We do that working a new approach and technique, approach we also use for working the dividends, unlike others, it can be also applied for every situation. 相似文献

The measurement of risk perception and risk attitudes, and their link to actual risk behaviors have been extensively discussed. However, the potential impact of perception of risk management instruments on the decision to use those instruments has rarely been addressed. This article hypothesizes that the degree of perception of insurance contracts and participation decisions could have substantial mutual influence depending on the development of the market. An empirical work is carried out based on a survey of data for paddy rice farmers in Hunan Province, China. It shows that the sampled farmers’ crop insurance perception was surprisingly low despite years of pilot programs and tens of billions of expenditure in government subsidies. The result of simultaneous equations model indicates that crop insurance perception and participation are simultaneously determined and mutually improving. Moreover, empirical evidence indicates that the impact of crop insurance participation on perception is slightly stronger than that of perception on participation, and thus provides weak evidence of a ‘learning-by-doing’ stage in China at present. Together with evidence of substantial local disparities in perception, implications for the Chinese government in further cultivating the crop and rural insurance market are discussed. 相似文献

This study examines unique factors causing emerging market firms to pursue functional upgrading. Our analysis draws on the resource-based view and learning theory, and our study sample consisted of Chinese new technology ventures. We test the effect of governance mechanisms and internal resources on the functional upgrading of firms. The results indicate that trade shows and quality advantage facilitated the functional upgrading of firms. However, contrary to our expectations, electronic markets and technological advancement do not emerge as significant variables. The implications of the results are discussed in consideration of the existing literature, and future research opportunities are described. 相似文献

We prove that the undetermined Taylor series coefficients of local approximations to the policy function of arbitrary order in a wide class of discrete time dynamic stochastic general equilibrium (DSGE) models are solvable by standard DSGE perturbation methods under regularity and saddle point stability assumptions on first order approximations. Extending the approach to nonstationary models, we provide necessary and sufficient conditions for solvability, as well as an example in the neoclassical growth model where solvability fails. Finally, we eliminate the assumption of solvability needed for the local existence theorem of perturbation solutions, complete the proof that the policy function is invariant to first order changes in risk, and attribute the loss of numerical accuracy in progressively higher order terms to the compounding of errors from the first order transition matrix. 相似文献
