Certain theories suggest that the capacity of a region to generate new firms, called entrepreneurship capital, has positive spillover effects on the production of the firms in that region. Evidence generated with aggregated data at the regional level supports this prediction. This paper argues that, using aggregated data at the regional level, entrepreneurship capital could be correlated with regional production even if entrepreneurship capital has no spillover effects on firm production. This will not be the case when data at the firm level are used. This paper provides evidence from a sample of 11,276 Spanish firms during the 2004–2012 period. Positive spillovers are estimated in between effects models, but such spillovers are only found in technological firms when within effects models have been estimated. Thus, the regional entrepreneurship capital spillovers are unclear when data at the firm level are used. Plausible interpretations and implications are discussed. 相似文献

We extend research on the consequentiality of stated preference choices to a threshold provision mechanism for public goods. We develop a simple theoretical model of option price to analyze how option price varies with payment and provision uncertainty. We explore whether threshold provision contributions are similarly influenced by payment and provision uncertainty using an induced value contribution experiment. Results suggest that: (1) the probability of payment has a negative effect on contributions; (2) the probability of provision has a positive effect on contributions. We offer subjective beliefs regarding payment and provision as a plausible systematic explanation for hypothetical bias. 相似文献

We examine the determinants of external crises, focusing on the role of foreign liabilities and their composition. Using a variety of statistical tools and comprehensive data spanning 1970–2011, we find that the ratio of net foreign liabilities to GDP is a significant crisis predictor. This is primarily due to the net position in debt instruments—the effect of net equity liabilities is weaker and net FDI liabilities seem, if anything, an offset factor. We also find that: i) breaking down net external debt into its gross asset and liability counterparts does not add significant explanatory power to crisis prediction; ii) the current account is a powerful predictor; iii) foreign exchange reserves reduce the likelihood of crisis more than other foreign asset holdings; and iv) a parsimonious probit containing those and a handful of other variables has good predictive performance in- and out-of-sample. The latter result stems largely from our focus on external crises sensu stricto. 相似文献

AbstractThis article, based in the body of strategic orientation literature, identifies and explores the practices of innovativeness, proactiveness and competitive aggressiveness that make up the strategic orientation implemented by subsistence entrepreneurs to improve business performance. A factor analysis was carried out using the data of 101 entrepreneurs, small artisanal business owners who operate in the subsistence markets in Oaxaca, Mexico. The results show that subsistence entrepreneurs notably engage in innovative and proactive practices, and, to a lesser extent, competitive aggressiveness. The research concludes that a combination of innovativeness with proactiveness is the most viable option for improving performance, whereas competitive aggressiveness impedes its development. Even so, however, it is still implemented by subsistence businesses in order to conserve their market share. 相似文献

Abstract The widely accepted belief that asset returns and insurance product line margins are not normally distributed has motivated the use of skewness (or higher than second-order moments) in the context of optimal risk-reward portfolio allocation. Here we propose an optimization-based methodology to substantially improve the skewness of portfolios in the mean-variance efficient frontier. Unlike other related methods, the proposed methodology is very intuitive, noniterative, and simple to implement, and it can be readily and efficiently carried out using state-of-the-art optimization solvers. These characteristics should be very appealing to risk managers. 相似文献

The annual structure of the real GDP in the UK, France, Germany and Italy is examined by means of fractionally integrated techniques. Using a version of a testing procedure due to Robinson (Journal of the American Statistical Association, 84, –37, 1994), it is shown that the series can be specified in terms of I(d?) statistical models with d higher than 1. Thus, the series are nonstationary and non-mean-reverting. The forecasting properties of the selected models for each country are also examined. 相似文献

This article studies the differences between traditional financial intermediaries (commercial banks, savings banks and cooperative
banks) and ethical banks based on property rights, in which the owner decides the ideology, principles, standards and objectives
of the organisation. In ethical banking, affinity centres on positive social and ethical values. The article consequently
focuses on an index proposed both to differentiate ethical banks from other types of banks, and also to pinpoint the differences
between the various ethical banks themselves. This is the Radical Affinity Index (RAI), which groups banks together in terms
of their stance on ethical commitment, concentrating on ethical ideology and principles (information transparency, placement
of assets, guarantees and participation) and using a sample of 114 European banks. The evidence shows that transparency of
information and placement of assets are factors that differentiate ethical banks from other financial intermediaries. Guarantees
and participation are characteristics specific to ethical banks; these variables, however, do not offer clear evidence to
our analysis. 相似文献

This paper offers a cross-country assessment of the governance of airport regulators in Latin America. The analysis links the institutional design of airport regulators, whether in the form of independent regulatory agencies or government departments, to their overall governance. It examines four dimensions of regulatory governance: autonomy, transparency, accountability, and bureaucratic quality. Independent regulatory agencies in the Latin American airport sector seem to provide a better framework for transparency and bureaucratic quality than government departments. It is not conclusively found, however, that independent regulatory agencies contribute to a more autonomous decision-making or to an enhanced accountability of regulators to other branches of government and airport users. Overall, governance indicators of airport regulators in Latin America are well below the threshold that defines good governance. 相似文献

Contingent Valuation: Controversies and Evidence 总被引:47,自引:8,他引:39
Richard T. Carson Nicholas E. Flores Norman F. Meade 《Environmental and Resource Economics》2001,19(2):173-210
Contingent valuation (CV) has become one of the most widely usednon-market valuation techniques. CV's prominence is due to itsflexibility and ability to estimate total value, includingpassive use value. Its use and the inclusion of passive use valuein benefit-cost analyses and environmental litigation are thesubject of a contentious debate. This paper discusses key areasof the debate over CV and the validity of passive use value. Weconclude that many of the alleged problems with CV can beresolved by careful study design and implementation. We furtherconclude that claims that empirical CV findings are theoreticallyinconsistent are not generally supported by the literature. Thedebate over CV, however, has clarified several key issues relatedto nonmarket valuation and can provide useful guidance both to CVpractitioners and the users of CV results. 相似文献

Environmental and socio-economic sustainability of chinampas (raised beds) in Xochimilco,Mexico City
Yair Merlín-Uribe Carlos E. González-Esquivel Armando Contreras-Hernández Luis Zambrano Patricia Moreno-Casasola 《国际农业可持续发展杂志》2013,11(3):216-233
The chinampas (raised beds) of Xochimilco, Mexico City, are highly productive, traditional wetland agricultural systems, which were able to feed most of the population in pre-hispanic times. There is a strong trend to substitute chinampas with plastic greenhouses for flower production, which creates negative impacts in the landscape, environment and culture. This study compares the environmental and socio-economic sustainability of chinampas and greenhouses, at both the farm and regional levels, using the MESMIS framework. Even though the results show that greenhouses are more profitable, the contribution of chinampas to ecosystem services cannot be substituted by greenhouses, as tree cover is lost, canals are filled and food is not provided. Greenhouses had a higher diversity, but also a higher agrochemical use and are heavily dependent on external inputs and subsidies. Chinampas have shifted from staple crops to commercial horticulture in order to remain a technically viable and economically feasible option for local farmers. However, compensation mechanisms for the provision of ecosystem services are urgently needed if this ancient system is to be maintained. The framework allowed the integration of indicators at both farm and regional scales, combining on-farm surveys with GIS techniques, which could assist in ecosystem service valuation. 相似文献
