Agricultural land abandonment and the consequent natural forest regrowth in areas once cultivated has significantly transformed Alpine ecosystems and landscapes. In this paper, we estimated the loss of agricultural areas due to reafforestation in the Belluno Province (Eastern Italian Alps) and integrated socioeconomic indicators with topographical features to evaluate the drivers of this change. Land use mapping, obtained from photo-interpretation of aerial photographs and technical maps, was used to quantify changes in forest and agricultural areas (crops, meadows and pastures) during the period of 1980–2000. On average, the forest surface expanded by 21%, while the agricultural areas decreased by 40%. This loss increased in areas with steeper slope, which confirms that the areas that would be first abandoned are those that are less productive and more difficult to manage. The reafforestation rate was particularly strong in the north of the province, where the livestock sector experienced a dramatic decline. In light of this situation and using multiple regression models with a large set of socioeconomic and agricultural indicators, we found that the loss of agricultural areas in 69 municipalities was primarily counterbalanced by the maintenance of livestock farming. The loss of steeper agricultural areas was counteracted by traditional extensive systems; however, it was not counteracted by modern intensive systems, which has important implications because steeper areas have higher landscape and biodiversity values. In addition, tourism development had a positive, although smaller, effect on the maintenance of agricultural areas, while industry development had a negative effect. The results of this study suggest that efforts are needed to maintain a territorial network of traditional extensive farms to avoid further landscape deterioration in Alpine areas. Likewise, certain choices toward the economic development of local communities might have an impact on land conservation. 相似文献

Since its foundation, the Fairtrade movement has attracted the attention of consumers, practitioners, media and scholars. Discussing the role that Fairtrade can play on a global yet locally rooted scale is very complex, as research reports contrasting results about its usefulness and effectiveness. This study examines scientific research on Fairtrade over the last decades by conducting a bibliometric analysis of the literature published on the ISI Web of Knowledge Core Collection, which included 876 papers by 1,293 authors in 432 journals. Results show that despite this being a relatively recent field of study, Fairtrade has been approached from different disciplines with different methodologies and objectives. The structured quantitative study of the literature enabled us to inspect how research has evolved over the years in the light of the changes faced by Fairtrade, to explore its scope in the broader field of the global market, to detect current research schools and perspectives within the network and to identify hitherto unaddressed issues and unconnected subfields. 相似文献

This paper presents stylized facts on labor supply, income, consumption, wealth, and several measures of consumption and income inequality drawn from the 1980–2006 Survey of Household Income and Wealth (SHIW) conducted by the Bank of Italy. The SHIW provides information on consumption, income and wealth, and a sizable panel component that allows econometricians to estimate sophisticated income, consumption, and wealth processes and to analyze labor market and portfolio transitions. We find that over the sample period income inequality is higher and has grown faster than consumption inequality. Most of the increase in income inequality is related to an increase in the degree of earnings' instability rather than to shifts in the wage structure. We suggest that, in particular, the labor market reforms of the 1990s and 2000s are the most plausible explanation of the increased earnings inequality. 相似文献

We suggest, by means of integration and cointegration tools, and error correction model regressions, that international risk
sharing is predominantly a short run concern. This finding has been obtained by using some new variants of the standard consumption
insurance tests, and runs counter to some other recent empirical evidence. Moreover, we find mixed evidence as to the fact
that the recent surge in international financial liberalization has improved on risk sharing, at least in the long run. 相似文献

Performance indicators are increasingly used to regulate quality in health care and the public sector. We develop a model of contracting between a purchaser and a provider under the following assumptions: (a) providers have private information about their own ability and (b) they can engage in costly manipulation of quality measures. If the contract is separating, manipulation reduces the optimal quality effort but increases the quality targets. If the purchaser's benefit from quality is sufficiently concave, then pooling of high-ability types (or all types) turns out to be optimal. (Partial) pooling provides a rationale for quality ceilings and minimum quality standards. 相似文献

Using data from a large panel of countries over the period 1995–2015, this article empirically investigates the effect of corruption on public debt. Overall, the estimates reveal that corruption increases public debt. The effect, however, appears to be heterogeneous across income-related sample splits: it is stronger for advanced economies, but weaker and less statistically robust for less-developed countries, where external factors such as foreign aid may also affect public debt. The analysis suggests the inadequacy of conventional wisdom assuming that more detrimental fiscal effects of corruption arise in low-income countries. 相似文献

In this study the authors investigate how dispersion of influence between Marketing and Sales (DIMS) affects the creation of superior customer value and the firm's market performance. Hypotheses are tested on a sample of 326 strategic business units using structural equation modelling analysis. Three main results emerge which contribute to the understanding of the consequences of DIMS within companies. First, DIMS increases interaction and collaboration between Marketing and Sales, without blurring their respective goals, roles and responsibilities. Second, DIMS contributes to the diffusion of a customer oriented-culture across the organization. Third, the findings of this study clarify how and why DIMS affects organizational performance by showing simultaneously that superior customer value mediates the effects of DIMS on market performance, and that Marketing–Sales interface and customer-oriented culture mediate the effects of DIMS on superior customer value. The authors discuss the study's theoretical contributions and offer directions for future research. Overall, this study provides a new and broader perspective to managers responsible for the allocation of decision making influence between Marketing and Sales over a range of market-related issues. 相似文献

Rapidly developing biotechnology applications aimed at improving major crops receive large investments and could, in theory, play a role in the promotion of underutilised plant species in the tropics and subtropics, in order to address current and emerging challenges for agriculture. The application of such methods is, however, sometimes controversial, and the frequently considerable costs involved must be weighed against the limited resources available to develop underutilised species, as well as against the many alternative methods available for promotion. Through database searches, we take an evidence-based approach to assess whether there are clear examples where biotechnology has been used practically to enhance the cultivation of underutilised plants at a field level. We conclude that tissue culture and micropropagation techniques have proven useful, but for other applications benefits are generally unclear at present, although ongoing work suggests genomic and genetic modification approaches may in future be significant for a subset of underutilised species. Successful outcomes, however, appear to be limited by a lack of integrated thinking during the use of biotechnology methods. We review the particular limitations and risks associated with applying biotechnology to underutilised crops, including the negative consequences of technology centralisation. In addition, the specific actions needed to ensure that smallholder farmers in low-income countries better benefit during the use of biotechnology on underutilised species, by placing a stronger emphasis on partnerships and by proper monitoring of benefits along value chains, are described. 相似文献

Awareness and Stock Market Participation 总被引:3,自引:0,他引:3
The paper documents lack of awareness of financial assets in the 1995 and 1998 Bank of Italy Surveys of Household Income and
Wealth. It then explores the determinants of awareness, and finds that the probability that survey respondents are aware of
stocks, mutual funds and investment accounts is positively correlated with education, household resources, long-term bank
relations and proxies for social interaction. Lack of financial awareness has important implications for understanding the
stockholding puzzle and for estimating stock market participation costs.
