Drought events are a major cause of large crop yield losses with implications for food security and farmers’ incomes. Growing multiple crops simultaneously during a cropping season is a well-known on-farm risk management strategy to cope with these drought risks. However, the effectiveness of this crop diversification under different severity levels of drought and how this effectiveness is influenced by the crop composition is unclear. This article provides new methodological and empirical insights to assess the effectiveness of such diversification, in particular to cope with extreme drought. We apply and evaluate nested Archimedean copulas and elliptical copulas to assess simultaneous farm-level yield losses of different cash crops in German agriculture (winter wheat, winter barley, winter rapeseed, sugar beet, and grain maize) under different drought severity levels (N = 249,756; regionally pooled farm-level crop-yield pairs, 1995–2019). We show that on-farm crop diversification contributes to cope with drought risks, but its effectiveness varies considerably across regions, crop pairs, and drought severity. Our results underline that cropping system diversification alone is often not sufficient to cope with drought risks, but that the right crop combinations are needed. For example, during a severe drought (one in 20 years event), 26.4% of farmers in eastern Germany suffered simultaneous yield losses of at least 20% in winter wheat and winter barley, while 19.1% of farmers in eastern Germany suffered simultaneous yield losses of at least 20% in winter wheat and sugar beet. Farmers should therefore be encouraged to grow crops with more diverse phenological requirements throughout the year. 相似文献

Tourism has, in recent times, been advocated as a particularly efficient way to promote the development of the so‐called less favoured regions, mostly inland and mountain, owing to its potential for employment and income creation and the synergies it is able to generate in other sectors of activity. Based on the results of empirical research carried out in two distinct inland zones of Portugal, this article tries to demonstrate that a wide gap and considerable contradictions are emerging between the rhetoric and the real benefits that tourism has been producing in the local societies and economies of these regions.

The conventional view argues that devaluation increases the price competitiveness of domestic goods, thus allowing the economy to achieve a higher level of economic activity. However, these theoretical treatments largely neglect two important effects following devaluation: (1) the inflationary impact on the price of imported intermediate inputs, which raises the prime costs of firms and deteriorates partially or totally their price competitiveness; and (2) the redistribution of income from wages to profits, which ambiguously affects the aggregate demand as workers and capitalists have different propensities to save. New structuralist economists have explored these stylized facts neglected by the orthodox literature and, by and large, conclude that devaluation has contractionary effects on growth and positive effects on the external balance. Given that empirical evidence on the correlation between devaluation and growth is quite mixed, we develop a more general Keynesian–Kaleckian model that takes into account both opposing views in order to analyze the net impact of currency depreciation on the short-run growth rate and the current account. We demonstrate that this impact can go either way, depending on several conditions such as the type of growth regime, that is, wage-led or profit-led, and the degree of international price competitiveness of domestic goods. 相似文献

Examining the database of applications to the Regional Government of Valencia's Institute for Small and Medium-sized Industries (Spain) for subsidies to aid technological development in small and medium-sized enterprises, this study seeks to explain the approval or rejection and the success or failure of projects that look to receive state funding. The independent variables in the database are particularly concerned with reliance on path dependence. The variable length of membership of the Institute, the number of previous applications, technology level, or belonging to a particular geographical area relate to the accumulation of experience and correspond to the study hypotheses. The study highlights the importance of accumulated experience and firm path dependence for application approval and success of funded projects. 相似文献

Recent moral and financial collapse of high profile organizations around the world led the business community, the popular and business press, and researchers to rediscover the worthiness of organizations' virtues. Aiming to contribute to this momentum, this empirical study investigates how perceptions of organizational virtuousness (OV) predict affective well-being (AWB) and affective commitment (AC). Two hundred five individuals participate. The findings show that perceptions of OV predict AC both directly and through the mediating role of AWB. The study suggests that fostering organizational virtuousness (e.g., through honesty, interpersonal respect, and compassion; combining high standards of performance with a culture of forgiveness and learning from mistakes) improves employees' AWB and promotes a more committed workforce. Considering these findings and mirroring the growing contributions of the positive psychology, positive organizational behavior, and positive organizational scholarship movements, the study suggests that a “positive-people-management” perspective should be considered, both by practitioners and scholars. 相似文献

This paper investigates the provision of financial services by banks as a two-stage production process involving three different basic activities. The first stage includes service activities, while the second stage comprises both investment-related and risk management activities. Financial services performance is assessed in terms of service efficiency and investment and risk management efficiency for years 2002–2010. The major empirical findings are that the Internet-primary bank is more efficient than most branching banks in deposit-raising activities, but with regard to investment and risk management activities, there are many brick-and-mortar banks that match the online bank performance. 相似文献

The purpose of this study is to examine the motivation to transfer training in a multidimensional way. It investigates autonomous and controlled motivation and explores the difference in motivation to transfer according to whether the employee is enrolled in training on a voluntary or mandatory basis. This is a cross‐sectional hypotheses‐testing study. Data were collected at a large insurance company involving employees who had participated in training programs in the previous 6 months. Findings show that when considering autonomous motivation to transfer, results support the argument that being voluntarily enrolled in the training program shows a higher impact on motivation to transfer than being mandatorily enrolled. When considering controlled motivation to transfer, results do not support such an argument, probably because of the nature of controlled motivation to transfer that in practice reduces the difference in results between the two types of enrollment. 相似文献
