This article is devoted to analysing the evolution of corporate governance mechanisms in Russia. Special attention is paid to the causes of dramatic discrepancies between the expected outputs of institutional reforms implemented by the Russian government with World Bank and IMF support and the actual behaviour of Russian companies. Why was the model of interaction between enterprises and investors, owners and managers, which had been successful in other countries, rejected by Russian business in the 1990s? And how can we evaluate certain positive changes that have occurred recently in corporate policies of major Russian companies? These questions are answered on the bases of analysis of economic agents' motivation at different stages of development of corporate structures in Russia. The article argues that the need for comprehensive organisational and technological restructuring of enterprises led to the need for a concentrated ownership structure. The formation of such a structure in the late 1990s (which occurred, in fact, contrary to the government's activities) created preconditions for extending the time horizon of dominant owners and managers and for positive qualitative changes in the relations between major Russian companies and their shareholders and investors.  相似文献

There is a debate on whether some forms of financial flows offerbetter protection against crises than others. Using a largepanel data set that includes advanced, emerging, and developingeconomies during 1970–2003, this article analyzes thebehavior of several types of flows: foreign direct investment(FDI), portfolio equity investment, portfolio debt investment,other flows to the official sector, other flows to banks, andother flows to the nonbank private sector. Differences acrosstypes of flows are limited with respect to volatility, persistence,cross-country comovement, and correlation with growth at homeor in the world economy. However, consistent with conventionalwisdom, FDI is the least volatile form of financial flow, whenthe average size of net or gross flows is taken into account.The differences are striking during "sudden stops" in financialflows (defined as drops in total net financial inflows of morethan percentage points of GDP compared with the previous year).In such episodes, FDI is remarkably stable, and portfolio equityseems to play a limited role. Portfolio debt experiences a reversal,though it recovers relatively quickly, and other flows (includingbank loans and trade credit) experience severe drops and oftenremain depressed for a few years.  相似文献

ABSTRACT

Stabilizing monetary policy in a small open economy is constrained by the open economy trilemma. In this paper, we investigate whether foreign exchange market interventions and the Central Bank’s credit rationing at the official rate (CROR) may soften this constraint and improve the results of monetary policy for different monetary regimes. We construct a dynamic stochastic general equilibrium (DSGE) model appropriate for analyzing the forward-looking behavior of households facing non-zero probabilities of losing access to financial market and CROR. We have found significant credit rationing in the quarterly Russian data of 2001:Q1–2014:Q2. The probability of losing access to financial market and the probability of CROR are estimated as 22% and 66%, respectively. Using Russian data of 2001:Q1–2014:Q2 we demonstrate that CROR provoked forward-looking activity in financial market, which led to more Ruble devaluation in the crises of 2008–2009. It improved poor countercyclical performance of two Russian monetary policy rules, whereas made small effect on welfare. Welfare maximization exercises reveal a tradeoff between low-inflation and high-welfare solutions and favor of a floating exchange rate regime. We found the optimal value of the probability of CROR in both exchange rate-based and Taylor rule-based models but resulting improvement in welfare is very small.  相似文献

Competition is the basic concept for both industrial organisation theory and institutional economics. Transition economies, including Russia, are natural laboratories allowing us to trace the emergence of competition, the influence of competition on the conduct of market participants, the relationship between competition and market structure and the institutional foundation of competition. This article provides a summary of the results of empirical studies in the above area. We try to explain some puzzles concerning the influence of competition on the conduct of Russian market participants and interpret the results in the framework of institutional and industrial economics. Overall, the results of empirical studies can be generalised as follows. Competition in Russian markets has been gaining momentum over the last 15 years. The results of empirical studies have confirmed the assumption that competition is an incentive for active restructuring of privatised enterprises. Many of the data collected are evidence in favour of the endogenous market structure approach. From the institutional viewpoint, the history of the evolution of Russia's transition economy shows interdependence between private property and competition: better protection of property rights is a precondition for the development of competition. At the same time, the model of corporate governance that allows the property rights of private owners to be protected in the Russian institutional environment restricts organisational diversity and therefore competition in Russian markets.  相似文献

Models of Multi-Category Choice Behavior   总被引:1,自引:0,他引:1  
Given the advent of basket-level purchasing data of households, choice modelers are actively engaged in the development of statistical and econometric models of multi-category choice behavior of households. This paper reviews current developments in this area of research, discussing the modeling methodologies that have been used, the empirical findings that have emerged so far, and directions for future research. We also motivate the use of Bayesian methods to overcome the computational challenges involved in estimation.  相似文献

Background:

Defensive medicine represents one cause of economic losses in healthcare. Studies that measured its cost have produced conflicting results.

Objective:

To directly measure the proportion of primary care costs attributable to defensive medicine.

Research design and methods:

Six-week prospective study of primary care physicians from four outpatient practices. On 3 distinct days, participants were asked to rate each order placed the day before on the extent to which it represented defensive medicine, using a 5-point scale from 0 (not at all defensive) to 4 (entirely defensive).

Main outcome measures:

This study calculated the order defensiveness score for each order (the defensiveness/4) and the physician defensive score (the mean of all orders defensiveness scores). Each order was assigned a weighted cost by multiplying the total cost of that order (based on Medicare reimbursement rates) by the order defensiveness score. The proportion of total cost attributable to defensive medicine was calculated by dividing the weighted cost of defensive orders by the total cost of all orders.

Results:

Of 50 eligible physicians, 23 agreed to participate; 21 returned the surveys and rated 1234 individual orders on 347 patients. Physicians wrote an average of 3.6?±?1.0 orders/visit with an associated total cost of $72.60?±?18.5 per order. Across physicians, the median physician defensive score was 0.018 (IQR?=?[0.008, 0.049]) and the proportion of costs attributable to defensive medicine was 3.1% (IQR?=?[0.5%, 7.2%]). Physicians with defensive scores above vs below the median had a similar number of orders and total costs per visit. Physicians were more likely to place defensive orders if trained in community hospitals vs academic centers (OR?=?4.29; 95% CI?=?1.55–11.86; p?=?0.01).

Conclusions:

This study describes a new method to directly quantify the cost of defensive medicine. Defensive medicine appears to have minimal impact on primary care costs.  相似文献

This study aimed to synthesize fragmented knowledge about international student mobility (ISM) in higher education to provide an understanding of existing studies and directions for future research. To this end, the authors conducted a systematic literature review using a hybrid approach that integrated bibliometric analysis with the theory, context, and method (TCM) framework (Paul et al., Journal of World Business, 2017;52(3):327–342). Applying bibliometric analysis, this study found publication trends, prolific journals, influential articles, and major themes in the field, whereas the TCM framework helped identify widely used theories (motivation theory, immigration theory, acculturation theory, learning theory, and capital theory), research contexts (destination country or region, population, and others), and methods in research and provided future study directions. The identified gaps in the existing literature suggest that future research should develop theoretical foundations and research designs to analyse new processes, patterns, and issues in ISM in higher education within the context of today's changing international environment. In addition to identifying the key research themes and research foundations of ISM in higher education, this review can help add value to the ISM literature from a marketing perspective. This is the first comprehensive literature review of this topic using a hybrid approach.  相似文献

In the underwriting and pricing of nonlife insurance products, it is essential for the insurer to utilize both policyholder information and claim history to ensure profitability and proper risk management. In this paper, we apply a flexible regression model with random effects, called the Mixed Logit-weighted Reduced Mixture-of-Experts, which leverages both policyholder information and their claim history, to categorize policyholders into groups with similar risk profiles, and to determine a premium that accurately captures the unobserved risks. Estimates of model parameters and the posterior distribution of random effects can be obtained by a stochastic variational algorithm, which is numerically efficient and scalable to large insurance portfolios. Our proposed framework is shown to outperform the classical benchmark models (Logistic and Lognormal GL(M)M) in terms of goodness-of-fit to data, while offering intuitive and interpretable characterization of policyholders' risk profiles to adequately reflect their claim history.  相似文献

We consider a class of Markovian risk models perturbed by a multiple threshold dividend strategy in which the insurer collects premiums at rate c i whenever the surplus level resides in the i-th surplus layer, i=1, 2, …,n+1 where n<∞. We derive the Laplace-Stieltjes transform (LST) of the distribution of the time to ruin as well as the discounted joint density of the surplus prior to ruin and the deficit at ruin. By interpreting that the insurer, whose gross premium rate is c, pays dividends continuously at rate d i =c?c i whenever the surplus level resides in the i-th surplus layer, we also derive the expected discounted value of total dividend payments made prior to ruin. Our results are obtained via a recursive approach which makes use of an existing connection, linking an insurer's surplus process to an embedded fluid flow process.  相似文献
