We show how policymakers in developing regions can generate richer insights from using the choice experiment method best-worst scaling (BWS) method when ranking policy priorities on an importance scale. More specifically, we adopt BWS to provide an update on constraints that limit the participation of Kenyan horticultural smallholder farmers in modern agricultural value chains. In addition to traditional constraints posed by input market failures and missing institutions, we considered constraints such as trust and familiarity with buyers shown by recent empirical studies to inform smallholders’ market choices. Ascertaining the relevance of these constraints highlights our contribution to the existing literature. We find that farmers consistently rate access to high-quality inputs as their main constraint followed by concerns about access to credit, the high cost of meeting food standards, missing cooperatives, and exploitative intermediaries. Respondents considered insufficient labor, small farmlands, and weak tenure rights as the least important constraints. Age, location, gender, household income, and education influence the relative importance various segments of smallholders place on these constraints. For example, constraints are economic rather than personal for low-income farmers. Counterintuitively, rural smallholders are less likely to perceive poor transportation network as a constraint. Smallholders’ distrust of buyers they interact with is informed by their location and income. In designing intervention initiatives, policies that focus on segments of smallholders are needed for improving smallholder participation in modern agricultural value chains.  相似文献

This paper analyzes demographic determinants of incident experience and risk perception, as well as the relationship between the two, for eight different risk domains. Analyses were conducted by merging the results of a Swedish population-based survey, which includes approximately 15,000 individuals, with demographic and socio-economic register data. Being male was associated with higher incident experience yet a lower risk perception for nearly all risk domains. Lower socioeconomic status was associated with higher incident experience for falls, and being a victim of violence but lower incident experience for road traffic accidents. Lower socioeconomic status was also associated with higher risk perception for falls. On aggregate, ranking the different domains, respondents’ risk perception was in almost perfect correspondence to the ranking of actual incident experience, with the exception that the risk of being a victim of violence is ranked higher than indicated by actual incident experience. On a demographic group level, men and highly educated respondents perceive their risks to be lower than what is expected considering their actual incident experience.  相似文献

This empirical study on small and medium‐sized enterprise growth investigates the relationship between motivation for growth, international orientation, and subsequent performance by following 247 firms over 11 years. Using a combination of regression analysis and structural equation modeling, the authors find the international orientation of the firm to be a consistent predictor of growth in revenue and exports. The authors also find the international orientation of the firm to be closely interrelated with motivation for growth: Firms with managers and owners having a strong motivation for growth tend also to have managers with high international orientation and display superior growth both domestically and abroad. Whereas motivation seems independent of past performance, it has a profound positive influence on the growth in revenue. Moreover, the findings reveal that some firms are able to sustain high growth rates over an extended period of time. The study supports the contention that some firms are able to systematically outperform the rest.  相似文献

This study examines the effect of road and railway noise on property prices. It uses the hedonic regression technique on a Swedish data set that contains information about both road and railway noise for each property, and finds that road noise has a larger negative impact on the property prices than railway noise. This is in line with the evidence from the acoustical literature which has shown that individuals are more disturbed by road than railway noise, but contradicts recent results from a hedonic study on data of the United Kingdom.  相似文献

In the literature, one of the main objects of stochastic claims reserving is to find models underlying the chain-ladder method in order to analyze the variability of the outstanding claims, either analytically or by bootstrapping. In bootstrapping these models are used to find a full predictive distribution of the claims reserve, even though there is a long tradition of actuaries calculating the reserve estimate according to more complex algorithms than the chain-ladder, without explicit reference to an underlying model. In this paper we investigate existing bootstrap techniques and suggest two alternative bootstrap procedures, one non-parametric and one parametric, by which the predictive distribution of the claims reserve can be found for other age-to-age development factor methods than the chain-ladder, using some rather mild model assumptions. For illustration, the procedures are applied to three different development triangles.  相似文献

Long-term economic development is determined by changes to the infrastructure, especially material and non-material infrastructural networks that link agents in different locations. The infrastructure consists of the slowly changing, collective arena that supports production, exchange, and consumption, such as the built environment, transport networks, and institutions. In the short run the infrastructure can be regarded as fixed. Changes to the infrastructure are under normal conditions small enough to be disregarded by producers and consumers. With the creation of a critical link of a network, there will however be a revolutionary restructuring of the arena. Critical links are here defined as additions to infrastructural networks that create opportunities for new information and transport flows between previously unconnected regions. Such a revolutionary restructuring of infrastructural networks has been called a logistical revolution. Certain institutional pre-conditions are necessary for a logistical revolution, while the creation of a critical link is both a necessary and a sufficient condition. This paper discusses the three logistical revolutions that occurred in the 13th century, around 1600, and in the 19th century, which each had crucial similarities with the current “information revolution.”  相似文献

Existing empirical evidence suggests that individual performance pay is more prevalent in human‐capital‐intensive industries. We introduce a model that can contribute to explain this. In a repeated game model of relational contracting, we analyze the conditions for implementing peer‐dependent incentive regimes when agents possess indispensable human capital. We show that the larger the share of values that the agents can hold up, the lower is the implementable degree of peer‐dependent incentives. In a setting with complementary tasks, we show that although team‐based incentives are optimal if agents are dispensable, it may be costly, and, in fact, suboptimal, to provide team incentives when the agents become indispensable.  相似文献

Real‐world financial contracts vary greatly in the combinations of cash flow contingency terms and control rights used. Extant theoretical work explains such variation by arguing that each investor finely tailors contracts to mitigate investment‐specific incentive problems. We provide overwhelming evidence from 4,561 venture capital (VC) contracts that this tailoring is overstated: even though there is broad variation in contracting across VCs, each individual VC tends to specialize, recycling familiar terms. In fact, a VC typically restricts contracting choices to a small set of alternatives: 46% of the time, a VC uses the same exact cash flow contingencies as in one of her previous five contracts. We document specialization in both aggregated downside protection, and in each individual cash flow contingency term. Such specialization remains economically and statistically significant even after controlling for VC and company characteristics. We also find that VCs learn to use new contractual solutions from other VCs in her syndication network. Our findings challenge the traditional premise that each investor selects from the universe of combinations of terms to match an investment's unique contracting problem. Rather, the cumulative evidence indicates that contract‐specialization arises because investors better understand payoff consequences of familiar terms, and are reluctant to experiment with unknown combinations.  相似文献
