Analyses of agricultural insurance failures often assume the existence of competitive supply, tracing the reasons for high insurance cost and limited farmer participation to informational problems, and suggesting the need for premium subsidization in order to increase participation. However, in countries such as Spain and Italy, where agricultural insurance is most highly subsidized, it could be that supply is not fully competitive. In this article, we explore the incidence of public subsidies to agricultural insurance premia when supply is noncompetitive. Through the use of a simple empirical model of an insurance market, it is shown that, while in the case of a competitive supply, subsidies to insurance would benefit farmers, a monopolistic supply would capture most of the subsidy, thus eliminating the potential incentive towards wider participation by farmers. The model is applied to a panel of Italian farms for different levels of risk aversion to demonstrate the limited effect that a subsidy to a hypothetical all risk yield insurance would have on farmer participation in the case of monopolistic supply. 相似文献

It is often claimed that, especially in mature industries, European firms can compete against low-cost NICs firms only if they are able to implement quality based strategies. The emphasis on the strategic role of quality, however, often leads to underestimate the extent of organizational and economic efforts, needed to turn quality from a potential opportunity into a real advantage. The lack of a thorough comprehension of the requirements of a quality based strategy can question the effectiveness of the investments some firms plan to improve their quality level. These firms can in fact remain stuck in the middle, if they do not have enough resources to turn quality into a source of sustainable competitive advantage.This paper is aimed at a better comprehension of both benefits and costs of a quality based strategy, with regard to a specific class of firms, Small Size Firms (SSFs), where a strategic use of quality is more difficult. The paper is articulated into two parts. Part one discusses the main obstacles facing the adoption of a quality based strategy by SSFs. A dynamic model for the adoption of this strategy over time, aimed at minimizing the risks for SSFs, is also presented.Part two describes the results of an empirical research, aimed at verifying the viability of quality based strategies in an industry composed only by SSFs, the shoe-machinery industry. The empirical research supports the viability of the model presented in the first part of the paper. 相似文献

We investigate whether accounting conservatism, which has been found to be effective in constraining management opportunism in other settings, constrains upward tone management (UTM) in the Management's Discussion and Analysis (MD&A) portion of the 10-K filing. We hypothesize that conservatism makes it harder for managers to opportunistically downplay bad news and magnify good news when discussing current performance. Consistent with this hypothesis, we find that UTM is negatively associated with several accounting conservatism proxies. Additionally, we hypothesize and find that this association is stronger for firms where managers have higher incentives to manipulate tone. In supplemental analyses, we find evidence to suggest that our results are not due to an endogenous relationship between conservatism and UTM. We also find that conservatism neither encourages downward tone management (DTM) nor constrains managers from conveying real information about future good news. Together, our results suggest that accounting conservatism improves disclosure narratives. 相似文献

The Distributional Efficiency of Alternative Regulatory Regimes: A Real Option Approach 总被引:3,自引:0,他引:3
This paper studies the effects of regulatory constraints on firm's irreversible investment decisions. The RPI–x rule is compared to a profit sharing rule, which increases the x factor in case profits go beyond a given level.When the firm has an option to delay investment, these rules have the same impact on investment choices. As profit sharing has a greater ability to extract rents, however, it is more efficient than the RPI–x rule. 相似文献

Targeting,bias, and expected impact of complex innovations on developing‐country agriculture: evidence from Malawi 下载免费PDF全文

Agronomic analyses of new technologies are often conducted under carefully controlled research station programs or trials managed by self‐selected farmers. Oftentimes, the technologies are then scaled up with minimal evaluation under real‐world conditions. Yet, the interim step between agronomic trials and large‐scale promotion is crucial to generate evidence on the social and economic impact of technologies that is both internally valid and generalizable. The article focuses on a participatory action research program in Malawi designed to test and identify scalable technology options to intensify the smallholder sector and contribute to poverty reduction and food and nutrition security. We examine the socioeconomic characteristics of farmers testing technologies and find evidence of systematic targeting of better‐endowed farmers. After controlling for observable differences using matching and a doubly robust estimator, we find evidence of early positive effects on maize yield and harvest value, although placebo tests suggest possible selection on unobservables. We note that attention should be given to program design and household characterization to better define and improve targeting criteria, technology selection, and external validity. 相似文献

The Dykstra and Laud's extended gamma process is assumed as prior process over the cumulative hazard function, (t), for a bayesian nonparametric estimation of the reliability functionR(t) from both exact and censored data. Particular cases and interpretative aspects are discussed also in the light of an illustrative example.This research was supported by Ministero della Pubblica Istruzione, grant 40% (Gruppo di ricerca «Modelli probabilistici»). 相似文献
