This paper investigates the cost efficiency of Russian banks with regard to their heterogeneity in terms of ownership form, capitalization and asset structure. Using bank-level quarterly data over the period 2005–2013, we perform stochastic frontier analysis (SFA) and compute cost efficiency scores at the bank and bank group levels. We deduct from gross costs the negative revaluations of foreign currency items generated by official exchange rate dynamics rather than by managerial decisions. The results indicate that the core state banks, as distinct from other state-controlled banks, were nearly as efficient as private domestic banks during and after the crisis of 2008–2009. Foreign banks appear to be the least efficient market participants in terms of costs, which might reflect their lower (and decreasing over time) penetration of the Russian banking system. We further document that the group ranking by cost efficiency is not permanent over time and depends on the observed differences in bank capitalization and asset structure. We find that foreign banks gain cost efficiency when they lend more to the economy. Core state banks, conversely, lead in terms of cost efficiency when they lend less to the economy, which can result from political interference in their lending decisions in favor of unprofitable projects Private domestic banks that maintain a lower capitalization significantly outperform foreign banks and do not differ from the core state banks in this respect. 相似文献

This study examines the informational efficiency of the bitcoin spot market by evaluating the predictive power of mechanical trading rules designed to exploit price continuation. Significant return predictability is found until the introduction of bitcoin futures in December 2017. The forecasting ability of trend‐chasing trading rules declines dramatically afterwards. Although evidence suggests that the introduction of bitcoin futures has increased the informational efficiency of the bitcoin spot market, no signs of improvement in informational efficiency are found in ethereum, the second‐largest cryptocurrency—following the introduction of bitcoin futures. 相似文献

ABSTRACTThis article investigates the role of international joint venture strategy of five multinational enterprises in the Russian construction market. Joint ventures play a crucial and specific role for these firms’ strategy in Russia: They serve both as an entry mode and a postentry strategy; facilitate business and guide foreign investors; increase efficiency for further strategy; and help international construction firms overcome the environmental deficiencies. Findings of the article bolster the theory by stressing the facilitating effect of joint venture upon challenges and problems that Western firms meet in emerging market in contrast with more developed economies. 相似文献

An occurrence of a market crash or a financial crisis has long been considered a cause of market inefficiency. An inefficient market commonly implies return predictability and the existence of profitable opportunities for traders and speculators. Technical analysis has been a popular tool to identify predictable patterns in asset prices. The usefulness of a large universe of technical trading rules popularized in the existing literature on technical analysis is tested when they are applied to a set of equity markets that are generally considered developed and efficient during the two most recent periods of major financial turmoil: the 1997 Asian financial crisis and the 2008 global financial crisis. Three major statistical deficiencies that existing studies on return predictability are commonly criticized for – data snooping bias, nonsynchronicity bias and transaction costs – have been incorporated in the analysis. Technical trading rules are largely unable to yield abnormal excess returns over the passive benchmark after data snooping bias, nonsynchronous pricing and transaction costs are accounted for. Chaotic price movements typical for a volatile market during a financial crisis are likely to have an adverse effect on the performance of active trend chasing trading strategies. 相似文献

Aims: Intermittent catheterization (IC) is the gold standard for bladder management in patients with chronic urinary retention. Despite its medical benefits, IC users experience a negative impact on their quality of life (QoL). For health economics based decision making, this impact is normally measured using generic QoL measures (such as EQ-5D) that estimate a single utility score which can be used to calculate quality-adjusted life years (QALYs). But these generic measures may not be sensitive to all relevant aspects of QoL affected by intermittent catheters. This study used alternative methods to estimate the health state utilities associated with different scenarios: using a multiple-use catheter, one-time-use catheter, pre-lubricated one-time-use catheter and pre-lubricated one-time-use catheter with one less urinary tract infection (UTI) per year.Methods: Health state utilities were elicited through an internet-based time trade-off (TTO) survey in adult volunteers representing the general population in Canada and the UK. Health states were developed to represent the catheters based on the following four attributes: steps and time needed for IC process, pain and the frequency of UTIs.Results: The survey was completed by 956 respondents. One-time-use catheters, pre-lubricated one-time-use catheters and ready-to-use catheters were preferred to multiple-use catheters. The utility gains were associated with the following features: one time use (Canada: +0.013, UK: +0.021), ready to use (all: +0.017) and one less UTI/year (all: +0.011).Limitations: Internet-based survey responders may have valued health states differently from the rest of the population: this might be a source of bias.Conclusion: Steps and time needed for the IC process, pain related to IC and the frequency of UTIs have a significant impact on IC related utilities. These values could be incorporated into a cost utility analysis. 相似文献

The aim of this article is to conduct an empirical investigation and reveal which types of modernisation strategies and characteristics of regional institutional environment are likely to be associated with patterns of the performance of Russian manufacturing firms in 2007–2012. In addition to estimating the impact of ex-ante behaviour on the rate of sales growth, we use hierarchical cluster analysis to reveal the typical trajectories of firms’ sales growth. We find that the dynamic of sales for more than 90% of firms can be described by just two types of performance curve: (a) crisis decline with recovery and growth; and (b) crisis decline with weak recovery and stagnation. Firms that invested more prior to the crisis and implemented active restructuring were more likely to have positive post-crisis dynamics of sales. We find evidence that firms in the regions with lower levels of corruption (both administrative and everyday) were more likely to recover successfully after the crisis. 相似文献

We study the profitability of traders in two fully electronic and highly liquid markets: the Dow and Standard & Poor?s 500 e-mini futures markets. Using unique information that identify counterparties to a transaction, we show and seek to explain the fact that the network pattern of trades captures the relations between behavior in the market and returns. Our approach includes a simple representation of how much a shock is amplified by the network and how widely it is transmitted. This representation provides a possible shorthand for understanding the consequences of a fat-finger trade, a withdrawing of liquidity, or other market shock. 相似文献

This article investigates the predictive power of technical trading rules in the emerging equity market sector portfolios and finds that trading strategies based on technical indicators significantly outperform the buy-and-hold benchmark. Combination of data snooping bias, data measurement errors in the form of non-synchronicity bias and fluctuations in currency exchange rates is unable to explain the observed outperformance. The introduction of transaction costs tempers the results but technical analysis still possesses significant predictive power for a number of sectors. The performance of technical analysis in the emerging equity market sectors does not conform to historical trends observed in the developed equity markets as well as in the emerging equity markets when broadly diversified portfolios are considered, where predictive power of technical trading rules has been shown to decline over time. 相似文献

Study design: A Markov model was used to analyze cost-effectiveness over a lifetime horizon.Objective: To investigate the cost-effectiveness of hydrophilic-coated intermittent catheters (HCICs) compared with uncoated catheters (UCs) among individuals with neurogenic bladder dysfunction (NB) due to spinal cord injury (SCI).Setting: A Canadian public payer perspective based on data from Ontario; including a scenario analysis from the societal perspective.Methods: A previously published Markov decision model was modified to compare the lifetime costs and quality-adjusted life years (QALYs) for the two interventions. Three renal function and three urinary tract infection (UTI) health states as well as other catheter-related events were included. Scenario analyses, including utility gain from compact catheter and phthalate free catheter use, were performed. Deterministic and probabilistic sensitivity analyses were conducted to evaluate the robustness of the model.Results: The model predicted that a 50-year-old patient with SCI would gain an additional 0.72 QALYs if HCICs were used instead of UCs at an incremental cost of $48,016, leading to an incremental cost-effectiveness ratio (ICER) of $66,634/QALY. Moreover, using HCICs could reduce the lifetime number of UTI events by 11%. From the societal perspective, HCICs cost less than UCs, while providing superior outcomes in terms of QALYs, life years gained (LYG), and UTIs. The cost per QALY further decreased when health-related quality-of-life (HRQoL) gains associated with compact HCICs or catheters not containing phthalates were included.Conclusion: In general, ICERs in the range of CAD$50–100,000 could be considered cost-effective. The ICERs for the base case and sensitivity analyses suggest that HCICs could be cost-effective. From the societal perspective, HCICs were associated with potential cost savings in our model. The results suggest that reimbursement of HCICs should be considered in these settings. 相似文献
