This article examines the driving factors of the effective corporate tax rate (ECTR) for a sample of companies listed on five Eastern European stock exchanges (Romania, Hungary, Poland, Bulgaria, and Slovenia), covering the period 2000–2016. The empirical research covers variables regarding firm characteristics (e.g., profitability, efficiency of assets, indebtedness, liquidity, and solvency), firm-level controls, auditing fees, and the statutory rate. The estimated panel data models provide support for a positive link between the ECTR and profitability, debt, capital and inventory intensity, firm size, and statutory rate, strengthening the validity of political cost theory. Further, the negative link between market capitalization and assets growth supports the idea of political power theory. 相似文献

European policy interest rates have been low and trending downwards for almost a decade now and expectations do not seem to change. Hence, in such an environment, this paper investigates whether and how banks’ prudential behavior has influenced profitability across the European banking sector from 1999 to 2015. Using a dynamic panel model, we clearly find that banks’ financial resilience, proxied by the asymmetric Z-score and two financial ratios, affects profits: more cautious banks record higher profits. This result is confirmed by the two overall measures of profitability, namely the Return on Average Assets and Equity, but not for the Net Interest Margins. Furthermore, our analysis suggests that monetary policy's main instrument adversely affects bank income. Nevertheless, when policy interest rates are particularly low, the effect on Net Interest Margin is still positive, while the effect on the overall profitability becomes negative. These results induce that European banks succeed in increasing their profitability despite a compression of their net interest income. 相似文献

We propose a new dynamic principal component CAW model (DPC-CAW) for time-series of high-dimensional realized covariance matrices of asset returns (up to 100 assets). The model performs a spectral decomposition of the scale matrix of a central Wishart distribution and assumes independent dynamics for the principal components' variances and the eigenvector processes. A three-step estimation procedure makes the model applicable to high-dimensional covariance matrices. We analyze the finite sample properties of the estimation approach and provide an empirical application to realized covariance matrices for 100 assets. The DPC-CAW model has particularly good forecasting properties and outperforms its competitors for realized covariance matrices. 相似文献

Recently, different bivariate Poisson regression models have been used in the actuarial literature to make an a priori ratemaking taking into account the dependence between two types of claims. A natural extension for these models is to consider a posteriori ratemaking (i.e. experience rating models) that also relaxes the independence assumption. We introduce here two bivariate experience rating models that integrate the a priori ratemaking based on the bivariate Poisson regression models, extending the existing literature for the univariate case to the bivariate case. These bivariate experience rating models are applied to an automobile insurance claims data-set to analyse the consequences for posterior premiums when the independence assumption is relaxed. The main finding is that the a posteriori risk factors obtained with the bivariate experience rating models are significantly lower than those factors derived under the independence assumption. 相似文献

In this work we introduce a jump-diffusion process for the euro overnight rate (the European over night index average) that is able to capture the main characteristics of this rate: (i) dynamics constrained to remain in the corridor of official rates fixed by the European Central Bank; (ii) mean reversion towards the official rate on main refinancing operations; and (iii) highly discontinuous pattern (with jumps), also without variations in the official rate. After calibrating the model parameters on historical data, we implement the model to price an overnight indexed swap. Finally, a comparison between our model and the most common short-term interest rate models is presented. 相似文献

The effects of a currency crisis on a country's economy depend on nonlinear relations among several variables that characterize the economic, financial, legal and socio‐political structure of the country at the onset of the crisis. Those effects can be associated with contractions or expansions in output. Historically, contractionary speculative attacks are more frequent. This paper uses a parametric censored heteroscedastic TOBIT model to empirically analyse how different economic and financial variables determine the real effects of a contractionary speculative attack. Variables describing the banking sector, the international trade, the severity of the crisis and foreign interest rates are found to be significant in explaining the size of currency crises' contractionary real effects. The TOBIT's results are compared with alternative modelling strategies. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

We present an integrated statistical model for assessing risk and projecting financial losses on automobile leases. The model
employs nonstationary Markovian state transitions for active leases and hierarchical logistic and regression equations for
different outcomes on termination. The model reveals that lower residual risks may partially offset higher credit risk for
customers whose credit scores predict higher risk of default. It also reveals a risk profile that differs through time from
other secured credits such as mortgages. A three-year follow-up of forecasts versus outcomes for 39,500 leasing contracts
shows that the model predicted rates of repossession better than standard roll-rate models with stationary transition probabilities.
It displayed similar accuracy in predicting unscheduled terminations and insurance settlements.

International oil demand is met by large government-owned producers, with remaining production divided between publicly traded Majors and Independents. This study compares publicly traded oil producer equity returns traded on the NYSE for the Majors and Independent US oil producers. Individual producer returns were related to equity and oil returns. Equity market risk is lower for large Majors and higher for smaller Independent rivals. Oil producers’ risk premiums associated with oil are smaller for large Majors and larger for smaller Independents. Natural gas returns generally do not affect producer returns. Major returns are inversely while smaller Independent returns are positively related to the size effect. Major oil producer returns are positively related to the value effect and negatively related to momentum. 相似文献
