The canonical economic literature on path dependence provides only a limited explanation of why and how new technological pathways are created initially. The motivation of this paper is to address this gap in the literature and argue that evolutionary economics theories of path dependence need to be linked with sociological explanations of how new technological pathways are created in the first instance by knowledgeable inventors and innovators. These arguments are developed by the authors in a hybrid socio-economic theory of new path creation. In this paper these theoretical arguments are illustrated empirically by a comparative analysis of the introduction and diffusion of new wind power technologies in Britain and Germany. The empirical analysis focuses on the key research question of why the introduction of these new technologies started earlier and has diffused sooner in Germany than in Britain. 相似文献

The average US state has 40 benefit mandates, laws requiring health insurance to cover particular conditions, treatments, providers or people. We investigate the extent to which these mandates increase the health insurance premiums paid by employers, and the extent to which these higher premiums are passed on to employees in the form of higher employee contributions. We use state-level data on premiums and employee contributions to health insurance from the insurance component of the 1996–2011 Medical Expenditure Panel Survey. Our main analysis is a fixed effects regression that controls for age, race, income, union membership and the presence of state mandate waivers. We find robust evidence that the average mandate increases premiums by approximately 0.6%, and that mandates lead to similar increases in employee contributions for single-coverage health insurance plans. Alternative specifications using an AR(1) error structure estimate a larger effect of mandates, while those using generalized estimating equations estimate smaller effects. We find that mandates requiring insurers to cover a specific benefit, as opposed to a specific type of provider or person, lead to the largest increases in employee contributions. 相似文献

This paper reviews the basic principles of inequality measurement, underlining the advantages and shortcomings of alternative measures from a theoretical standpoint and in the context of the study of the distribution of wealth. Adopting the two most popular measures, the Gini index and the P‐shares, the paper documents wealth inequality in Canada using the 1999, 2005 and 2012 Survey of Financial Security (SFS). It carries out several decompositions with covariates, featuring DFL‐type reweighting methods and Gini and P‐shares RIF regressions. The latter parallel decompositions deepen our understanding of how changes in socio‐demographic characteristics, including the compensating role of family formation and human capital, impact wealth inequality. 相似文献

Cotton, both a source of livelihood for millions of poor rural households and a major source of export revenues, is a vital commodity for the economic and social development of Mali. Inefficiencies in the Malian cotton system at the ginnery and producers’ cooperative levels (e.g., late payment to farmers and poorly functioning credit schemes) have recently led to an important decline in supply, threatening the sustainability of the sector. Using regional data from 1998/1999 to 2008/2009, this study aims to quantitatively assess the contribution of key determinants, such as cotton prices and timely payment, toward the downward trend in cotton area. A dynamic supply model, based on adaptive expectations and partial adjustment, is employed to estimate the effects of prices and institutional factors, such as credit recovery rates and date of payment to farmers, on the Malian cotton supply. Results show that supply responds significantly to cotton prices relative to cereal and fertilizer prices. Date of payment varies across agricultural cycles and late payment negatively influences land devoted to cotton. Low credit repayment rates create disincentives to grow cotton. Therefore, the revitalization of the Malian cotton sector depends upon getting both prices and institutions right. 相似文献

Behavioral economics (BE) examines the implications for decision-making when actors suffer from biases documented in the psychological
literature. This article considers how such biases affect regulatory decisions. The article posits a simple model of a regulator
who serves as an agent to a political overseer. The regulator chooses a policy that accounts for the rewards she receives
from the political overseer—whose optimal policy is assumed to maximize short-run outputs that garner political support, rather
than long-term welfare outcomes—and the weight the regulator puts on the optimal long run policy. Flawed heuristics and myopia
are likely to lead regulators to adopt policies closer to the preferences of political overseers than they would otherwise.
The incentive structure for regulators is likely to reward those who adopt politically expedient policies, either intentionally
(due to a desire to please the political overseer) or accidentally (due to bounded rationality). The article urges that careful
thought be given to calls for greater state intervention, especially when those calls seek to correct firm biases. The article
proposes measures that focus rewards to regulators on outcomes rather than outputs as a way to help ameliorate regulatory
biases. 相似文献

Optimal sequencing of resource extraction is typically studied for nonrenewable resources. We provide conditions for optimal use of multiple sources of a renewable resource and characterize the resulting extraction sequence, resource scarcity values, and (single) efficiency price path for two groundwater aquifers and an abundant alternative resource. Even with one demand, the optimal sequence depends on the differential opportunity costs of the two renewables. A numerical simulation for the South O‘ahu aquifer system, which also allows for different distribution costs, illustrates the case of using the “leakier” aquifer first and then switching to simultaneous use of both resources. The welfare gain from specialization relative to independent management is $4.7 billion. 相似文献

This paper is an expository introduction to several topics of current research in the general equilibrium theory of rational expectations. More specifically, we discuss the existence of exact and approximate rational expectations equilibria, the implementation of equilibria, the behavior of learning and smoothing processes by which traders construct expectations from repeated observations of the market, and the lagged use of the information revealed by prices in an intertemporal sequence of markets. The purpose of this discussion is to introduce papers on these topics appearing in the Journal of Economic Theory Symposium on Rational Expectations in Microeconomic Models. 相似文献

金融中介及关系银行——基于广东外资企业银行融资数据的研究 总被引:27,自引:1,他引:27
本文根据外资银行和国有商业银行向在中国境内的外资企业提供的外币贷款和人民币贷款的数据 ,对金融中介及关系银行进行了实证研究。我们的主要结论有两点 :第一 ,企业与银行建立起来的金融业务关系越长久 ,那么其所获得的外币贷款利率就越低。这是对金融中介理论的支持。另外 ,外资控股、第三方担保等因素 ,也具有降低外币贷款利率的效应。第二 ,人民币贷款的利率随着外资企业与更多的银行建立和保持合作关系而降低。人民币贷款主要是由我国商业银行提供。如果商业银行间的竞争仅仅是用来作为信贷定价的主要决定因素 ,而不是用来推进金融创新 ,提供高质量的金融产品和服务 ,那么这将会损害我国商业银行的获利能力并进而影响金融系统的健康发展。 相似文献

Labor arbitration helps define employee and employer rights and responsibilities. Evidence indicates that the advocates at
arbitration tend to concern themselves with issues unrelated to the facts of the case or to the rights and responsibilities
of the parties involved. More specifically, before the hearing, management and union advocates often dwell on issues such
as the importance of the arbitrators’ personal characteristics and their decision-making history, the likely effects of the
gender of arbitrators and grievants, and whether the presence of legal counsel impacts the arbitral outcomes. The purpose
of this study is to examine whether these non-case-related factors actually can be associated with differing awards by arbitrators.
This study may be the first in which the arbitrators’ decision-making history (award orientation) is a primary issue. Of all
the issues studied, the arbitrator’s disciplinary award orientation is the only one with a consistent impact on arbitral outcomes.
We conclude that the energy and resources expended by the advocates concerning non-case-related issues would be better spent
in preparing their cases for arbitration and in examining the potential impact of arbitration on the rights and responsibilities
of management and its employees. 相似文献
