An increasing number of tropical timber‐producing nations have enacted bans on export of logs arguing that this will reduce deforestation, expand downstream wood processing and improve the scale efficiency of domestic processing, create jobs and retain more value‐added nationally. The theoretical literature is clear that trade restrictions are generally welfare reducing (except in special cases such as when there is a potential for an optimal export tax). At best, a log export ban is a second‐best policy tool for reducing deforestation and addressing the associated environmental externalities. In overall terms, the suggestion that log export bans can achieve the objectives expected of them is dubious. However, very little quantitative evidence exists to demonstrate this claim and the paper attempts to address this gap by looking at the economic and environmental impacts of eliminating a log export ban in Costa Rica. The authors argue that eliminating the export ban is Pareto improving and could generate economic gains as high as $14 million per annum with the possibility of relatively modest environmental benefits. 相似文献

Tourist and recreational use of natural and protected areas in Argentine–Chilean Great Lakes Tourist Corridor has experienced a remarkable growth during last years. Although total amount of use is still within these areas admission capacity, problems arise derived from intensive use in certain places, as well as visitors management concerns in considered critical areas. In this context, a research project was elaborated, approaching the problem of alternative tourism activites management, and focusing on aspects referred to their management and administration in the area of Binational Corridor. This paper refers to one of the dimensions considered in the project: alternative tourism activites demand in the Corridor. Starting from the classification of sustainable tourism niches done by Eagles (1994), a segmentation matrix was prepared and applied. Such analysis has important research, planning and market implications and is critical to the development of suitable services as well as to the design of appropriate management strategies and techniques for those institutions in charge of tourism planning in wilderness areas. Results are not only valid for those activities mentioned in the area of study, but also for other outdoor activities management in the context of North-Patagonian protected areas. 相似文献

This paper uses fractional integration models to describe the long‐run dependence of nominal exchange rates in Central and Eastern European countries (CEECs). The analysis is validated using nonparametric, semiparametric and parametric techniques. From comparing the results across the three approaches, it was clear that mean reversion takes places only for the euro exchange rates in Bulgaria, Estonia, and Slovenia. Other exchange rates based on the euro also display mean reversion with the parametric methods. For the US dollar rates, the unit‐root null hypothesis cannot be rejected in any single country, indicating that shocks affecting the exchange rates against the US dollar are of a permanent nature, while those directed against the euro are less persistent, and tend sometimes to disappear in the long run. Policy implications are derived. 相似文献

Self-regulation (SR) is a common way of enforcing quality in markets (such as banking, financial services and several professions) and in a variety of public and private organizations. We provide experimental evidence of the reputational incentives of self-regulatory organizations (SROs) to publicly disclose versus cover-up fraud in an incomplete information environment. We find that observed behaviour is generally consistent with Bayesian equilibrium when subjects are informed about the relative likelihood of fraud detection by a ‘vigilant’ versus a ‘lax’ SRO type. In particular, a fraud disclosure equilibrium is supported when subjects are informed that the ‘vigilant’ SRO is more likely to detect fraud; otherwise, a cover-up equilibrium is supported. However, when subjects are not informed about the relative likelihood of fraud detection by the SRO types (as expected in real SR situations), no equilibrium is strongly supported. Our results suggest that in practice, the reputation-based incentives for effective SR may be inherently ambiguous and weak. 相似文献

Agora Partnerships is a micro venture capital fund founded by Benjamin Powell in the US and Ricardo T. Teran in Nicaragua. Agora started operations in 2005 with the goal of identifying and supporting entrepreneurs and business plans with high potential for success. The fund faces some unique challenges. First, the size of the businesses that is investing in does not allow for a traditional “management fee” structure. Secondly, traditional investment exits are nearly impossible in Nicaragua. This teaching case includes analysis on sources of investment capital, deal structures, and expected returns. The unresolved dilemma remains how to structure an investment proposal attractive to both investors and entrepreneurs. The case also allows discussing how to adapt the venture capital model to an emerging country like Nicaragua. 相似文献

Recent theoretical models (Carlson, Fisher, and Giammarino, 2004) predict an association between the book-to-market equity ratio (BE/ME) and operating leverage in the cross-section. Consistent with these models, we find a positive association between BE/ME and the degree of operating leverage (DOL), between DOL and stock returns, and between DOL and systematic risk. Overall, our findings provide support for a risk-based explanation for the value premium that is consistent with existing theoretical models. The evolution of systematic risk associated with firm-level investment activity, rather than financial distress, seems to be the main determinant of the value premium. 相似文献

Mutual aid often entails the sharing of knowledge. We investigate how, in turn, knowledge sharing affects the long-run dynamics of mutual aid. In our economy, agents with specific knowledge are “held up” by their principals. Inside communities, agents aid each other by sharing their specific knowledge. This process generates a new type of knowledge which exacerbates the specificity of the existing types and induces more agents to engage in mutual aid. However, since the knowledge generated is shared, it progressively renders agents inside communities more flexible and, thus, less dependent on mutual aid. We characterize conditions under which in the long-run mutual aid spreads or is abandoned. 相似文献

In this article, we test to determine whether a reallocation of government budgetary components can enhance long-term GDP
growth in a set of 15 EU countries. We apply panel data techniques to the period 1971–2006, and use three alternative dependent
variables in a growth regression: economic growth, total factor productivity and labour productivity. Our results also identify
the distortions induced by public expenditure in the private factors allocation. In particular, we detect a strong crowding-in
effect associated to public investment, which has enhanced economic growth by boosting private investment. We also associate
a dependence of productivity on public expenditure on social security. 相似文献
