The VIX, the stock market option-based implied volatility, strongly co-moves with measures of the monetary policy stance. When decomposing the VIX into two components, a proxy for risk aversion and expected stock market volatility (“uncertainty”), we find that a lax monetary policy decreases both risk aversion and uncertainty, with the former effect being stronger. The result holds in a structural vector autoregressive framework, controlling for business cycle movements and using a variety of identification schemes for the vector autoregression in general and monetary policy shocks in particular. The effect of monetary policy on risk aversion is also apparent in regressions using high frequency data.  相似文献

This article investigates regional income convergence in Russia during 2000–2008. We test the hypothesis in which income divergence across regions of the country should give place to income convergence as the country moves toward free market economy with strong market institutions. The study contributes to the existing literature by using the exponential smooth autoregressive Augmented Dickey–Fuller (ADF) unit root test in a panel setup, a novel econometric technique, which encompasses cross sectional dependence. Results show strong evidence of on-going regional income divergence in post-reform period.  相似文献

The purpose of this article is to present and discuss the values and limits of microfinance within the context of poverty reduction, international development, and community empowerment. The main thesis is that microfinance requires a more complex strategy than simply the provision of credits. The development of financial capital depends on the increase in human capacity and social capital. Microfinance is revisited under the ethical lenses of global responsibility for alleviating poverty and developing community sustainability. Through a critical review of the literature and case studies from the Philippines, the author suggests a value-based Vincentian approach to integrate microfinance into community empowerment. In connection with the main thesis the author argues that the achievement of economic self-reliance through microfinance is contingent upon the development of capacity building, social capital, and empowerment at the individual, collective, and systemic levels.  相似文献

The aim of this paper is to understand what economic mechanisms may cause the Law of Proportionate Effect to break down for fast-growing and shrinking firms. Recent evidence has highlighted that the first-order coefficients of quantile auto-regression of firm size decline across quantiles. Our theoretical results show that negative variance–size scaling is sufficient to yield a decline in quantile auto-regression coefficients if firm log-size is Laplace-distributed, conditional on size one period ahead. However, it is sufficient only for declining auto-regression coefficients for fast-growing firms under Asymmetric Laplace conditional log-size if skewness is decreasing with size. In other words, if the growth of large firms is less dispersed and more left-skewed, size is a disadvantage for the growth of fast-growers, but not necessarily an advantage for fast-decliners. Thus, size-related determinants of negative growth skewness, such as diseconomies of growth, market power, and managerial attention issues, impact on how the LPE is violated. Using data on Dutch manufacturing companies from the Business Register of Enterprises observed between 1994 and 2004, our empirical estimates of quantile regression models confirm the evidence of declining quantile regression coefficients for small–medium firms (20–199 employees) mainly in the right-most quantiles, and for the same subsample, we find that growth rates variance and skewness are decreasing with size. The theoretical propositions of the paper are thus corroborated.  相似文献

This paper considers a government that chooses its tax and borrowing policy in order to minimize the present value of the excess burden caused by taxation. In doing so, the government uses hyperbolic discounting. It turns out that public deficits are positive even if public expenditures are constant over time. With cyclical expenditures, the government chooses an asymmetric debt policy, i.e., in bad times it borrows more than it repays in good times. In contrast to tax smoothing and political economy theories of public debt, the welfare effects of a balanced budget rule are ambiguous.  相似文献

Guilds provided for masters' and journeymen's burial, sickness, old age, and widowhood. Guild welfare was of importance to artisans, to the functioning of guilds, to the myriad of urban social relations, and to the political economy. However, it is an understated and neglected aspect of guild activities. This article looks at welfare provision by guilds, with the aim of addressing four questions. Firstly, for which risks did guild welfare arrangements exist in the Netherlands between 1550 and 1800, and what were the coverage, contributions, benefit levels, and conditions? Secondly, can guild welfare arrangements be regarded as insurance? Thirdly, to what extent and how did guilds overcome classic insurance problems such as adverse selection, moral hazards, and correlated risks? Finally, what was the position of guild provision in the Dutch political economy and vis‐à‐vis poor relief?  相似文献

Technology does not have intrinsic value: obtaining competitive advantage from it and transforming it into profits requires a business model based on the application of competencies and dynamic capabilities, and the ability to select and apply appropriate resources. Innovative 3-D printing technology appears to be dependent on a new business model based on the ability to structure and integrate creative inputs, crowdsourcing processes, and market distribution networks. This new business model is being used by design enterprises that employ 3-D printing technology in order to enrich their service portfolio or to inaugurate completely new business lines. This paper analyzes how the use of new 3-D printing technology in design enterprises is coupled with proper business model components. Through a qualitative analysis of three cases - Quirky, i.materialise and Fab-Lab - the authors develop four propositions on a number of factors that contribute to business model effectiveness in design ventures using 3-D printing technology.  相似文献

ABSTRACT

Hybrid professional managers appear less effective in introducing management into public professional settings than policymakers hope. To date, research has offered little understanding of professionals’ identity transition challenge and the role of social interactions underpinning this process. We studied the identity work of hybrid doctors inside a large public health-care organization, finding that it takes place through processes of familiarizing with management, rationalizing being a hybrid, and legitimizing the new role-identity. We contribute to the literature by showing that identity work is distributed and enabled by social interactions beyond the professional group. Implications for policymakers and executives are discussed.  相似文献

Until now the promotion of renewable energies in Europe has been effected on the basis of different promotion systems of the Member States. Currently the EU-wide harmonisation of the promotion systems, from which yields of efficiency and a higher effectiveness are expected, cannot be enforced due to a discordance concerning the “right” promotion instrument.With the proposal for a directive on the promotion of renewable energies, published at the 23. January in 2008, the European Commission attempts to make a first move towards harmonisation. Besides existing promotion systems it will be possible to transfer Guarantees of Origin for renewable energies between Member States. Since, however, some Member States expect negative effects as a consequence of opening their markets the proposal comprises opportunities to restrict the transfer. The present scope of interpretation within the proposal allows for different options concerning the design of the transfer restrictions. These will be identified, analysed, and subsequently evaluated in this article. Despite of both extreme options, the possibility to entirely opt out of the transfer system and the obligation to completely participate in the transfer system, two further hybrid options are discussed. The latter are characterised by the possibility of Member States to restrict the transfer of Guarantees of Origin to a certain extent through a “system of prior authorisation”.  相似文献

Defending Gibrat’s Law as a long-run regularity   总被引:1,自引:0,他引:1  
According to Gibrat’s Law of Proportionate Effect, the growth rate of a given firm is independent of its size at the beginning of the period examined. While earlier studies tended to confirm the Law, more recent research generally rejects it. This article reconciles these two streams of literature, taking into account the role of market selection and learning in reshaping a given population of firms through time. Consistently with previous studies, we find that Gibrat’s Law has to be rejected ex ante, since smaller firms tend to grow faster than their larger counterparts. However, a significant convergence toward Gibrat-like behavior can be detected ex post. This finding is an indication that market selection “cleans” the original population of firms, so that the resulting industrial “core” does not depart from a Gibrat-like pattern of growth. From a theoretical point of view, this result is consistent with those models based on passive and active learning, and can be seen as a defense of the validity of the Law in the long-run.
