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

The paper inquires into the efficiency of financial development policies in economies where the financial sector is based on oligopolistic commercial banking. In this case, interest rates on deposits may be set below the level required to achieve balance of payments equilibrium, so that banks are able to exact a risk free financial margin in their holdings of government bonds. Under such circumstances, banks lack incentives to place indirect debt in domestic security markets, as a means of providing long-term finance; and private capital market deepening is hindered. Pension fund privatisation, in this institutional environment, does not relieve public finances, because the government must act as issuer of last resort in order to stabilise the currency. This point is illustrated with Mexican data, and some policy measures to deal with this situation in developing economies are proposed.  相似文献

This paper provides a case study of the 2001/02 famine in Malawi from a village in the Southern Region of the country. Based on in‐depth micro‐level field research, it challenges some commonly accepted views about this crisis. The paper provides evidence that: (1) there was a serious ‘famine’ in the community; (2) the decline in food availability was not the major causal factor of the famine; (3) the early warning system in the rural areas was functioning appropriately and the famine did not happen in ‘silence’, unnoticed; (4) the food preferences of Malawians are not ‘inflexible’; and (5) the famine, contrary to the claims of some of the ‘new famine hypotheses’, was less the consequence of underlying vulnerability and long‐term social or economic trends but, rather, the result of an unexpected and sudden shock, which was generated by the exponential increase in the price of all food crops.  相似文献

This paper proposes a GARCH-type model allowing for time-varying volatility, skewness and kurtosis. The model is estimated assuming a Gram–Charlier (GC) series expansion of the normal density function for the error term, which is easier to estimate than the non-central t distribution proposed by [Harvey, C. R. & Siddique, A. (1999). Autorregresive Conditional Skewness. Journal of Financial and Quantitative Analysis 34, 465–487). Moreover, this approach accounts for time-varying skewness and kurtosis while the approach by Harvey and Siddique [Harvey, C. R. & Siddique, A. (1999). Autorregresive Conditional Skewness. Journal of Financial and Quantitative Analysis 34, 465–487] only accounts for non-normal skewness. We apply this method to daily returns of a variety of stock indices and exchange rates. Our results indicate a significant presence of conditional skewness and kurtosis. It is also found that specifications allowing for time-varying skewness and kurtosis outperform specifications with constant third and fourth moments.  相似文献

The transitional recession in the new Central and East European members of the EU called for completely novel approaches to industrial policy in the nineties. A strong rejection of industrial policy could be observed only in some countries and during the first years of the transition process. Subsequently however, deteriorating competitiveness, soaring unemployment and the dramatic condition of key export sectors made the re-appearance of supply-side economic policy thinking inevitable in most Central East European Countries (CEECs), except for such small and open economies as Slovenia and Estonia. A wide variety of industrial policies implemented in the CEECs are compared in the study, with special emphasis on tools used in order to promote incoming foreign direct investment, technological development and the small and medium-sized enterprise sector. These elements of the industrial policy toolkit will keep their key role in most CEECs, albeit their industrial policies will gradually align themselves to the European mainstream.  相似文献

This article analyzes the factors determining the intention to use the websites of the rural tourism accommodations to search for information and to make online reservations. Based on the Technology Acceptance Model (TAM), a model is developed to explain the intention to use the websites, incorporating as explanatory variables the perceived usefulness and perceived ease of use (basic variables of the TAM) and the following key attributes of tourism websites: information, interactivity, and navigability. The results of a sample of 1083 users indicate that (1) the perceived usefulness is the main direct antecedent of the intention to use the websites to search for information and make online reservations, and that (2) information on the accommodation and destination positively influences the perceived usefulness, whereas both the interactivity and navigability have a positive effect on the perceived ease of use of the websites.  相似文献

Previous empirical research suggests that university spin-offs under-perform in economic terms compared to other new technology-based firms (NTBFs) in their early years. The usual explanations suggest a lower capabilities endowment of university spin-offs compared to other NTBFs. Using a longitudinal Spanish dataset we compare the evolution of firms′ total factor productivity (capabilities endowment) in both kinds of firm. Productivity grew faster in university spin-offs and their initial underperformance disappeared after 2 or 3 years of operation. The evidence therefore suggests that university spin-offs have lower initial substantive capabilities but greater dynamic capabilities than independent NTBFs. Possible explanations are discussed.  相似文献

Most oil refineries and factories producing basic chemical products are located in port areas, with the result that industrial complexes potentially have a strong environmental impact on their area of influence. These externalities result in a loss of welfare for citizens residing in neighbouring areas. In a context of sustainable development, companies must integrate concerns about the natural environment in their business strategy. External stakeholders, as residents, find it difficult to visualize the actions firms take to reduce their environmental impact, and the adoption of voluntary certified environmental management systems (EMSs) acts as a signal indicating the adequate environmental behaviour of these companies. These certifications enable companies to achieve the social legitimacy they need for long‐term survival and competitiveness. In the context of a petrochemical industrial complex located in the port of Castellón (Spain), this paper primarily discusses whether such certifications – which act as signals of firms’ desirable environmental conduct – translate into higher trust in firms and lower risk perception by residents. Contrary to what might be expected, despite the widespread use by companies of voluntary and certified EMSs, the research findings confirm a relatively high citizen perception of risk regarding the industrial complex and a low trust in companies. On the other hand, the findings also show a low trust in the public institutions responsible for authorizing and monitoring firms’ activities and for enforcing possible sanctions in non‐compliance cases.

This article aims to understand the determinants influencing the number of association meetings held in countries worldwide and which may be controlled by their economic agents and policymakers. For this purpose, we use a dynamic panel model with data provided by the Data World Bank, the World Travel & Tourism Council, and the International Congress and Convention Association, in a time series of 8 years. The results reveal the importance of the experiences obtained by the tourists in previous meetings, as well as the countries’ need to implement measures to stimulate the dynamism of economic activity and political stability.  相似文献
