A note on tax competition in the presence of agglomeration economies

This paper analyzes tax competition in the presence of agglomeration effects. The obtained results are then compared to the results of the traditional model, without agglomeration effects. As is well known, the presence of a fiscal externality affects the provision of the public good in the standard competitive model of tax competition. In the model with agglomeration effects, in addition to this externality, a new effect shows up. This effect reflects heightened government concern about capital flight, which depresses firm productivity by limiting external economies of scale. As a result, capital tax rates end up being lower than in the case where agglomeration effects are not present, worsening the underprovision of the public good. This conclusion holds in both the competitive and strategic versions of the model.     

Efficiency in Third Sector Partnerships for Delivering Local Government Services: The role of economies of scale,scope and learning

Abstract

Third sector partnerships are under pressure to change in the light of the increasing cost pressures on local public services. The literature throws doubt on the level of economies of scale and suggests that more attention should be given to economies of scope and learning. The common conflation of economies of size with economies of scale has led policymakers to overemphasize larger scale providers and has distorted the strategies which third sector organizations have adopted, pushing them towards mergers and consortia based on scale.     

A note on the equilibrium theory of economies with asymmetric information

In this note, we give an equilibrium existence theorem for exchange economies with asymmetric information and with an infinite dimensional commodity space. In our model, we assume that preferences are represented by well behaved utility functions, the positive cone has a non empty interior and the individual rational utility set is compact. Our result complements the corresponding one in Podczeck and Yannelis (2008), in the sense that is applicable to commodity spaces in which the order intervals are (possibly) not compact with respect to any Hausdorff linear topology.     

Efficiency, productivity, and scale economies in the U.S. property-liability insurance industry

The paper examines efficiency, productivity and scale economies in the U.S. property-liability insurance industry. Productivity change is analyzed using Malmquist indices, and efficiency is estimated using data envelopment analysis. The results indicate that the majority of firms below median size in the industry are operating with increasing returns to scale, and the majority of firms above median size are operating with decreasing returns to scale. However, a significant number of firms in each size decile have achieved constant returns to scale. Over the sample period, the industry experienced significant gains in total factor productivity, and there is an upward trend in scale and allocative efficiency. More diversified firms and insurance groups were more likely to achieve efficiency and productivity gains. Higher technology investment is positively related to efficiency and productivity improvements.     

Modelling the inflation process in transition economies: Empirical comparison of Poland, Hungary and Czech Republic

This paper starts from the observation that inflation in transition economies appears to be persistently high and volatile and attempts to provide some empirical characterisation of the inflation process in three such transition economies: Poland, Hungary and Czech Republic. We first consider the role of monetary growth as a major causal factor for inflation in these economies, and argue that the evidence provides rather weak support for the causal relationship. We then propose a transition economy cost-plus model and estimate this using the equilibrium-correction modelling (ECM) strategy augmented by introduction of a number of transitory factors and changes in the internal structure of the real economy which we believe may have had a significant impact on inflation in these economies. We show that this approach enables us to account for long-run inflation in these economies from the early 1980s to the present despite the turbulence of the latter part of the sample period. Our results support wage and exchange rate based inflation policies.     

Equilibria in large economies with a separable Banach commodity space and non-ordered preferences

The purpose of this paper is to provide an existence result of equilibria for economies with a measure space of agents, a non-trivial production sector and an infinite dimensional commodity space. The commodity space is modeled by an ordered separable Banach space whose positive cone has a non-empty interior. The discretization approach proposed in this paper, allows us to extend the existence results in Khan and Yannelis [Equilibrium in markets with a continuum of agents and commodities. In: Khan, M.A., Yannelis, N.C. (Eds.), Equilibrium Theory in Infinite Dimensional Spaces. Springer, Berlin, 1991] and Podczeck [Economic Theory 9 (1997) 585] to economies with a non-trivial production sector and with possibly non-ordered but convex preferences as well as partially ordered (possibly incomplete) but non-convex preferences.     

垂直关系、效率原则与社会福利研究

企业之间的垂直关系主要包括垂直一体化和垂直分离,具体选择哪种垂直关系,企业需要在规模经济、交易成本和提高成员激励的各种得失中进行权衡。从社会福利和产业组织政策来看,处于不同市场结构中的企业,其进行垂直一体化和垂直分离的效率后果不尽相同,由此也导致了不同的社会福利水平。     

A Note on the Probability of Having a Strong Condorcet Winner

In an election, a strong Condorcet winner is a candidate who is top-ranked by more than 50% of the voters. The purpose of this note is to provide some algebraic representations for the probability of having a strong Condorcet winner in three-candidate elections. Three alternative procedures for generating voting situations are considered: the Impartial Culture condition, the Impartial Anonymous Culture condition and the Maximal Culture condition. It turns out that the conclusions we obtain strongly depend on the way for generating voting situations.     

A Note on the Technical and Allocative Efficiency of Local Exchange Carriers in the United States

The issue explored is whether incentive regulation of local exchange carriers in the United States has resulted in an increase in efficiency. After providing an overview of the nature of incentive regulation, the methodology for measuring the effects of incentive regulation on efficiency is reviewed. This methodology is data envelopment analysis and allows for the measurement of both technical efficiency and allocative efficiency of individual local exchange carriers. The results of empirically implementing the DEA approach indicate that there is little change in technical efficiency. In fact average technical efficiency in 1988 was the same as in 2001. Next, while outputs continued to grow at about their historical rate across LECs, the sizeable increase in the two types of capital increased inputs well above their historical average rates for some LECs leading to short run allocative inefficiency. On average, however, allocative efficiency shows no identifiable trend between 1988 and 2001. Finally, in the aggregate, total economic efficiency does not demonstrate any trend between 1988 and 2001.     

A note on CEO compensation, elimination tournaments and bankruptcy risk

We investigate an economy in which firms have different risks to go bankrupt. We observe two things: first, workers in firms with higher bankruptcy risk (bad firms) always work less than workers in good firms. Second, the CEOs of bad firms may nonetheless receive larger wages.JEL Classification: J40, L20, M50Alexander Matros: We are grateful to Karl Wärneryd and an anonymous referee for helpful suggestions.

A note on consistency and unbiasedness of point estimation with fuzzy data

Based on the SLLN for fuzzy random variables in uniform metric d, some asymptotical properties of point estimation with fuzzy random samples are investigated. The results of this paper establish a corresponding version on the consistency and unbiasedness of point estimation with n-dimensional fuzzy samples under considering a kind of fuzzy statistic.     

Resource-envy-free and efficient allocations: A new solution for production economies with dedicated factors

I consider the problem of determining an equitable and efficient allocation of resources in production economies with factors which must be dedicated to production and cannot be consumed directly. First, I show that in such economies envy-free and efficient allocations exist under standard assumptions. However, I argue this notion of fairness is unsuitable for the present context. I then introduce a new notion of fairness, which I call resource-envy-freeness. First, I associate with each consumption bundle its resource footprint consisting of the vector of factors used to produce it. I then show that preferences over consumption bundles can be extended to preferences over factor bundles. An allocation is resource-envy-free if no agent prefers another agent’s resource footprint to its own. The analysis of resource-envy-free allocations in production is exactly analogous to the analysis of envy-free allocations in exchange. I establish that resource-envy-free and efficient allocations exist under standard assumptions, and I demonstrate that such allocations are intuitively appealing.     

A note on strategies for bandit problems with infinitely many arms

A bandit problem consisting of a sequence of n choices (n) from a number of infinitely many Bernoulli arms is considered. The parameters of Bernoulli arms are independent and identically distributed random variables from a common distribution F on the interval [0,1] and F is continuous with F(0)=0 and F(1)=1. The goal is to investigate the asymptotic expected failure rates of k-failure strategies, and obtain a lower bound for the expected failure proportion over all strategies presented in Berry et al. (1997). We show that the asymptotic expected failure rates of k-failure strategies when 0<b1 and a lower bound can be evaluated if the limit of the ratio F(1)–F(t) versus (1–t)^b exists as t1^– for some b>0.     

A note on the asymptotic relative efficiency of M.L.E. in a linear model with Gamma disturbances

The statistical properties of the maximum likelihood estimator (M.L.E.) of the parameters of a linear model with Gamma distributed residuals are analysed. Some previous results of the literature on this topic are corrected, allowing the computation of the asymptotic relative efficiency of the M.L.E. over the O.L.S.     

The impact of participative leadership on job performance and organizational citizenship behavior: distinguishing between the mediating effects of affective and cognitive trust

This study examines the mediating effects of cognitive trust and affective trust on the relationship between supervisors' participative leadership behavior and subordinate work outcomes, using data obtained from 247 dyads in a manufacturing organization located in mainland China. Structural equation modeling revealed that while affective trust fully mediated the relationships between participative leadership of supervisor and subordinate job performance and organizational citizenship behavior, cognitive trust had non-significant effects. These findings underscore the importance of interpersonal interactions between the supervisor and subordinate for engendering subordinate work outcomes. They also lend support to the exchange (relationship)-based explanation as to how trust enhances the response of subordinates to the participative leadership behavior of their immediate supervisor, given that affective trust involves a process of social exchange between both parties over an extended period of time.     

Family-friendly management,organizational performance and social legitimacy

Research on family-friendly practices has concentrated on the predictors of their use, particularly from the perspective of either institutional theory or the high involvement or commitment management vogue. This paper first shows how such perspectives can be used to generate hypotheses about the link between family-friendly management and organizational performance. Second, the paper reports research designed to test these, using data from a national representative sample of workplaces across the British economy, the Workplace Employment Relations Survey of 2004 (WERS2004). The results support the high commitment thesis that family-friendly management will strengthen the relationship between commitment and key economic outcomes, as the relationships between workforce commitment and productivity or quality are stronger in organizations when friendly management is high, which is consistent with social exchange theory. Family-friendly management is not, however, related to the human resource outcomes of labour turnover and absenteeism. Nor does the study find support for the argument that its use in conjunction with high involvement management enhances the performance effects of both. Equally, there is no support for the hypothesis from the institutional thesis that family-friendly management has positive effects on the legitimacy of the organization.     

法律制度、法律执行与上市公司破产重整效率——基于宝硕股份的案例研究

破产重整是危机企业解除财务危机的重要法定机制。本文基于执法经济学理论,以宝硕股份的破产重整事件为例,研究了新破产法实施后上市公司破产重整的经济效率。研究发现,虽然宝硕股份借助重整机制暂时避免了破产清算,但是重整活动却明显缺乏经济效率,新破产法在执行过程中偏离了原先的立法预期,相对落后的执法环境致使参与重整的利益相关方的目标函数和博弈行为发生异化,并最终导致重整的低效率。本文揭示了我国转型期相对落后的执法环境制约企业破产重整效率的典型作用路径。最后,本文提出了若干政策建议。     

Encouraging employees to co-operate: the effects of sponsored training and promotion practices on employees' willingness to work overtime

The ‘mutual-investment’ model argues that when employers invest more in the social exchange relationship between them and their employees, their employees will show more effort. In this paper we relate the ‘mutual-investment’ model to training and promotion (possibilities) and examine if these kinds of career-enhancing measures influence the willingness of employees within organizations to work overtime. To test this hypothesis, a vignette experiment was conducted in five organizations (N = 388; 1,531 vignettes). Multilevel analyses show that employees are more willing to work overtime when their employer has provided for training, when the employee recently was promoted, when the supervisor was supportive in the past and when co-workers approve of working overtime and behave similarly. But we did not find that future promotion chances affect willingness to work overtime.     

供应链的权力、契约、信任网络及其特征——基于社会网络分析

针对近年来供应链不再仅仅局限于企业内部或者某一链条上而是形成了企业间的供应链网络这种现象,基于理论演绎和社会网络分析,对供应链网络及其特征进行了探索性研究。首先基于格里菲提出的市场型、模块型、关系型、受制型、层级型治理结构模型,从社会网络角度对五种供应链治理结构的网络特征做了初步探索,进而构建了五种治理结构的交易网络和社会网络,其中社会网络又分为权力网络、契约网络和信任网络。通过分析发现,市场型治理结构的契约网络比较密集,关系型治理结构的信任网络比较密集,而层级型治理结构的权力网络比较密集。     

Impacts of Monetary, Fiscal and Exchange Rate Policies on Output in China: A Var Approach

Applying the VAR model and using the interest rate as a monetary policy variable, we find that in the long run, output in China responds negatively to a shock to the interest rate, the real exchange rate, government debt, or the inflation rate, and it reacts positively to a shock to government deficits or lagged own output. When real M2 is chosen as a monetary policy variable, long-term output in China responds positively to a shock to real M2 or lagged own output, and it reacts negatively to a shock to the real exchange rate, government debt, or government deficits. Its response to a shock to the inflation rate is negative when government debt is used and is positive when government deficits are considered. In the short run, fiscal policy is more important than monetary policy in three out of four cases. In the long run, monetary policy is more influential than fiscal policy in three out of four cases. Therefore, the government may consider conducting monetary and fiscal policies differently in the short run and long run. The government needs to be cautious in pursuing deficit spending as its long-term impacts depend on the monetary variable employed. The policy of maintaining a relatively stable exchange rate is appropriate as the depreciation of the Yuan may hurt the economy in the short run.JEL Classifications: E5, F4, H6
