We seek to quantify the success of Russia's attempt to achieve price-liberalization initiatives as part of the reforms established under the Big Bang of January 1992. We do so by studying the time-series behavior of commodity prices between 1992–1995 and focusing on the relationship between the behavior of prices of similar goods within and across cities. We supplement this analysis by examining city-level surveys that seek to quantify the extent to which firms are currently able to set and adjust commodity prices in accordance with market conditions. Our evidence suggests that price liberalization gradually gained momentum following the Big Bang and that prices generally reflected market conditions by the first quarter of 1995. However, regional pockets of resistance to price-reform efforts continue to persist, indicating that Russia has yet to achieve full market integration.J. Comp.

THE ROLE OF FINANCIAL CAPITAL IN PRODUCTION 总被引:1,自引:0,他引:1
It is increasingly acknowledged that the financial structure of a firm is an important determinant of its production costs. This paper argues that the use of a firm's liabilities should be seen as a separate input in the production process. At the same time, the input of non-financial assets is limited to the value that is used up during the reference period. The paper elaborates on these ideas and shows their use in empirical work. It is concluded that the approach set out in this paper establishes a much closer relationship of general economic accounting and analysis to business economics. 相似文献

Whether judges and prosecutors should be given full discretionary power in sentencing or mandatory minimum sentences be imposed remains a fiercely debated topic. In this paper, we examine the impact of Canada's 2005 introduction of minimum sentences on sexual offences against children and child pornography on the distribution of sentence lengths using administrative data containing the universe of these offences that occurred between 2003 and 2007. We find that the average sentence length for affected crimes at times increased by substantially more than the newly imposed minimum, and effects of the policy appear even in the middle and upper portions of the sentencing distribution. These increases occur immediately following the policy change, signalling that judges and prosecutors quickly change their sentencing behaviour after the implementation of mandatory minimum sentences. These lengthier sentences have significant implications for the estimation of the fiscal costs of minimum sentencing policies. 相似文献

Taking the approach of the superfirm, we characterize government organization through six different features. First, citizens are viewed as sovereign owners of a superfirm; elected officials are employees of the sovereign citizens. Second, in analogy to the economic principle of the division of labor and specialization, a division of labor between five independent branches of government is advocated: the legislative, the budgetary, the executive, the law enforcement, and the judiciary branch. Third, we do not suggest a mechanism of checks and balances between government branches but deal with the threat of tyranny using the principle of separation of decision control and decision management developed by Eugene Fama and Michael Jensen. Fourth, with election as a decision control device, we demarcate the constituency of the budgetary branch by age groups to provide an explicit control mechanism for intertemporal and intergenerational trades. Fifth, to strengthen sovereign citizens' decision control, the powers to recall elected chief public servants, to declare emergency and war, to sign into international treaties, and to amend the constitution are vested with a national assembly. Sixth, there is no head of state. 相似文献

Strategy-proofness (SP) is a sought-after property in social choice functions because it ensures that agents have no incentive to misrepresent their private information at both the interim and ex post stages. Group strategy-proofness (GSP), however, is a notion that is applied to the ex post stage but not to the interim stage. Thus, we propose a new notion of GSP, coined robust group strategy-proofness (RGSP), which ensures that no group benefits by deviating from truth telling at the interim stage. We show for the provision of a public good that the Minimum Demand rule (Serizawa (1999)) satisfies RGSP when the production possibilities set satisfies a particular topological property. In the problem of allocating indivisible objects, an acyclicity condition on the priorities is both necessary and sufficient for the Deferred Acceptance rule to satisfy RGSP, but is only necessary for the Top Trading Cycles rule. For the allocation of divisible private goods among agents with single-peaked preferences (Sprumont (1991)), only free disposal, group replacement monotonic rules within the class of sequential allotment rules satisfy RGSP. 相似文献

This paper investigates the effect of nearby nature substitute sites on preferences for nature restoration. Contrary to prior studies, we use a respondent-centric approach to control for substitute sites. We assess each respondent-specific spatial context by computing densities of nature substitute sites within various ranges from each respondent’s home. This approach considers the use and non-use values of nature together. Data from three similar discrete choice experiments carried out in Flanders (Belgium) are compared. Different spatial discounting factors are tested to explore how the substitution effect behaves with regard to distance. Latent class analyses are performed to account for preference heterogeneity among respondents. We observe divergent behaviours across groups of respondents. The “distance-to-substitutes” affects how respondents gauge substitute sites. We find a significant influence of the squared average buffer distance but this effect varies in sign across case studies and classes of respondents. Our results demonstrate that individual-specific GIS data can significantly improve the representation of the spatial context and the transferability of value functions. However, the roles played by preference heterogeneity and nature perception on respondents’ capacity to value nature still deserves further attention in future research. 相似文献

Commodity cash and futures prices experienced a severe boom-and-bust cycle between 2006 and 2009. Increases in commodity price volatility have raised concerns about the usefulness of commodity futures and options as risk management tools. Dynamic hedging strategies have the potential to improve risk management when conditional (co)variances depart significantly from their unconditional, long-run counterparts and may be useful to decision-makers despite their greater complexity and higher transaction costs. We propose a Nonparametric Copula-based Generalized Autoregressive Conditional Heteroscedastic (NPC-GARCH) approach to estimate time-varying hedge ratios, and evaluate the benefits of dynamic hedging during four sub-periods between 2000 and 2011 using a stylized Texas cattle feedlot management problem. The NPC-GARCH approach allows for a flexible, nonlinear and asymmetric dependence structure between cash and futures prices for different commodities. We find that NPC-GARCH dynamic hedging performs better than either static, GARCH-Dynamic Conditional Correlation (DCC) or GARCH-Baba, Engle, Kraft and Kroner (BEKK) hedging in terms of lower tail risk (expected shortfall), but that there is no significant difference between hedging approaches in terms of portfolio variance reduction. 相似文献

This paper examines various Austrian theories of entrepreneurship through the lens of complexity theory, more specifically via the concept of a dancing fitness landscape. Problems in many fields (including economics) can be characterized as attempting to find the highest peak on a fitness landscape (which corresponds to an efficient or optimal resource allocation). A rugged fitness landscape is one characterized by many peaks and troughs, while a dancing fitness landscape is one where the peaks and troughs change over time due either to exogenous or endogenous activity. I argue that several key disagreements among Austrian economists can be better understood through the metaphor of a fitness landscape. The implications of this insight for various branches of Austrian economics are also considered. This study is timely as radical Austrian views are starting to percolate into business schools leading to increased debate among management scholars about the precise nature of the entrepreneurial process (Chiles et al. 2007; Sarasvathy and Dew 2008; Alvarez et al. 2010). 相似文献
