We study a dynamic version of Meltzer and Richard's median‐voter model where agents differ in wealth. Taxes are proportional to income and are redistributed as equal lump‐sum transfers. Voting occurs every period and each consumer votes for the tax that maximizes his welfare. We characterize time‐consistent Markov‐perfect equilibria twofold. First, restricting utility classes, we show that the economy's aggregate state is mean and median wealth. Second, we derive the median‐voter's first‐order condition interpreting it as a tradeoff between distortions and net wealth transfers. Our method for solving the steady state relies on a polynomial expansion around the steady state.  相似文献

For many kinds of capital, depreciation rates change systematically with the age of the capital. Consider an example that captures essential aspects of human capital, both regarding its accumulation and its depreciation: a worker obtains knowledge in period 0, then uses this knowledge in production in periods 1 and 2, and thereafter retires. Here, depreciation accelerates: it occurs at a 100% rate after period 2, and at a lower (perhaps zero) rate before that. The present paper analyzes the implications of non-constant depreciation rates for the optimal timing of taxes on capital income. The main finding is that under natural assumptions, the path of tax rates over time must be oscillatory. Oscillatory tax rates are optimal when depreciation rates accelerate with the age of the capital (as in the above example), and provided that the government can commit to the path of future tax rates but cannot apply different tax rates in a given year to different vintages of capital.  相似文献

We study the impact of tax and transfer programs on steady-state allocations in a model with search frictions, an operative labor supply margin, and incomplete markets. In a benchmark model that has indivisible labor and incomplete markets but no trading frictions we show that the aggregate effects of taxes are identical to those in the economy with employment lotteries, though individual employment and asset dynamics can be different. The effect of frictions on the response of aggregate hours to a permanent tax change is highly nonlinear. There is considerable scope for substitution between “voluntary” and “frictional” nonemployment in some situations.  相似文献

The authors' analysis of the patenting activity of 472 companies that received private equity investments between 1986 and 2005 provides suggestive evidence of an increase in the effectiveness (though not necessarily the quantity) of their innovative activities. After such companies received private equity backing, the patents they applied for received more frequent citations than patents awarded before the involvement of PE firms. Companies acquired by private equity also show no sign of deterioration in patent “originality” and “generality,” which have been shown to be fairly reliable indicators of the fundamental nature of the research. And while there is no clear pattern of change in the level of patenting activity, corporate patent portfolios become more focused in the years after the private equity investments. The increases in our measure of patent “impact” are greatest in the areas that constitute the companies' historical core strengths. These findings are likely to prove increasingly important as private equity continues its incursions into growth areas of the economy.  相似文献

This paper offers a new political economy explanation for thepervasive problem of siting hazardous waste treatment facilitiesin federal system. We first show that a decentralized systemyields the first-best waste treatment capacity level and that acentralized structure gives rise to free-riding behavior amonglocal jurisdictions. In our model, each community seeks toinfluence the central government through political contributions.This leads to suboptimal levels of treatment capacity. Thecapacity is increasing in the compensation level if the marginalbenefit of treatment capacity is sufficiently large, and in thegovernment's weight on aggregate social welfare relative tolobbying activities. The centralized system can replicate thedecentralized system with a sufficiently high compensation level.Since compensation has proved difficult, a centralized systemfaces greater obstacles than a decentralized system.  相似文献

This article empirically investigates if firms focusing on service innovation perform better financially than firms not focusing on service innovation. Analysis of the financial performance of 3575 Norwegian firms in the manufacturing industries supports the proposition that firms focusing on service innovation have significantly higher growth of operating results than firms not focusing on service innovation. However, this proposition is not supported in a corresponding analysis of 1132 Norwegian firms in the service industries. We elaborate on these results by investigating a variety of performance measures and by comparing the effects of service innovation between manufacturing and service industries. The article contributes to the service innovation measurement literature and to a better general understanding of the determinants of service innovation performance effects.  相似文献

In recent years a growing stream of research has examined the relationships between structural characteristics of regions and their levels of new firm formation. This empirical study aims at supplementing such findings with analyses that include other forms of business dynamics, and also the possible well-being effects of such dynamics. From a unique and comprehensive data set that tracks all births, deaths, expansions, and contractions of commercial business establishments in Sweden 1985–89, six groups of regions with different patterns of dynamics are extracted by means of cluster analysis. The clusters' structural characteristics and their development of economic well-being are also compared. The results suggesta) that the patterns of business dynamics are contingent on the structural characteristics of regions,b) that high formation and turnover of establishments are associated with a relative increase in economic well-being, andc) that small, autonomous firms have a vital role in this process.  相似文献

This study explores the relationship between new venture team composition and new venture persistence and performance over time. We examine the team characteristics of a 5-year panel study of 202 new venture teams and new venture performance. Our study makes two contributions. First, we extend earlier research concerning homophily theories of the prevalence of homogeneous teams. Using structural event analysis we demonstrate that team members?? start-up experience is important in this context. Second, we attempt to reconcile conflicting evidence concerning the influence of team homogeneity on performance by considering the element of time. We hypothesize that higher team homogeneity is positively related to short term outcomes, but is less effective in the longer term. Our results confirm a difference over time. We find that more homogeneous teams are less likely to be higher performing in the long term. However, we find no relationship between team homogeneity and short-term performance outcomes.  相似文献

Injuries pose an economic problem of immense proportion to communities in every society. The economic burden from injuries can be quantified through cost-of-injury studies, using techniques adopted from cost-of-illness research. This study explores the feasibility of applying results and methodologies from existing cost-of-injury studies in economic analyses of injury prevention interventions and programmes. The literature on cost-of-injury studies and economic appraisals of injury prevention efforts was examined to elicit studies that calculated injury costs. Studies were accepted for inclusion if they included an analysis of the costs of all injuries occurring in a geographical area (community, region or country) during a specific time period, employed a societal perspective and an incidence-based costing approach and were conducted in industrialized countries. There were 12 studies that met the inclusion criteria. The average total cost per injury case was USD $3536, while the average share of indirect to total cost per injury case was 71%. However, the cost figures showed wide variation across the studies. Based on the limited similarity of findings from the studies, it was concluded that it is not feasible to apply results and methodologies from existing cost-of-injury studies. The cost estimators described in this study could possibly be adapted for use as reference points in economic analyses of existing programmes, but any other uses should be approached with caution. Locally obtained data are needed for reliable economic analyses of injury prevention interventions and programmes.  相似文献
