Evaluating agricultural programmes requires considering not only the programmes’ influence on input and output indicators, but also considering the relationship between these indicators as embodied in the production technology. This article examines the impact on production of an intervention in the Ecuadorian Sierra designed to improve returns to potato production through training and through linking smallholders to high‐value markets. Critical to identifying the impact of the programme is the careful construction of a counterfactual and meticulous data collection. To assess the impact of the programme on production, a weighted estimation, where weights are constructed through propensity score matching, is employed to estimate a production function within a damage abatement framework. The function incorporates a series of interaction terms to assess the impact of the programme on the production technology. The findings provide evidence that the programme enhances yields both through a general shift in technology as well as increased input use. The results suggest that the use of effective farming techniques that are learned through the programme induce this technological shift.  相似文献

This paper focuses on time preference and individual measures of expropriation risk. We use survey data on Italian households and on the 50+ population in eleven European countries. The surveys provide measures of discount rate and proxies for expropriation due to criminal offenses. We show that impatience increases with expropriation risk.  相似文献

We study the effect of the size of the welfare state on demographic trends in OECD member countries. Exploiting exogenous variation in public social spending, due to varying degrees of political fractionalization (i.e., the number of relevant parties involved in the legislative process), we show that an expansion in the welfare state increases fertility, marriage, and divorce rates with a quantitatively stronger effect on the marriage rate. We conclude that the welfare state supports family formation in the aggregate. Further, we find that the welfare state decouples marriage and fertility, and therefore alters the organization of the average family.  相似文献

ABSTRACT: The aim of this paper is to introduce a multidimensional assessment model for organizations that have multiple goals and are not driven exclusively by profit. Therefore, it is an assessment method particularly suitable for social enterprises. In order to measure the efficiency of production units in each dimension, the Data Envelopment Analysis non‐parametric method is applied. Our case study is concerned with Fair Trade shops and members of the consortium Altromercato for which we collected variables that could be associated with input and output for the economic, socio‐cultural and organizational dimensions. The results of the analysis confirm the presence of economies of scale in the economic dimension but not in the socio‐cultural dimension. Moreover, our organizational analysis confirmed a low general professionalization. Our results also confirm, on the one hand, the more pronounced capacity of cooperatives to sell Fair Trade products compared to associations, which, on the other hand, have the tendency to achieve proportionately better results in the socio‐cultural dimension.  相似文献

The aim of this paper is to test for stochastic monotonicity in intergenerational socio‐economic mobility tables. In other words, we question whether having a parent from a high socio‐economic status is never worse than having one with a lower status. Using existing inferential procedures for testing unconditional stochastic monotonicity, we first test a set of 149 intergenerational mobility tables in 35 different countries and find that monotonicity cannot be rejected in hardly any table. In addition, we propose new testing procedures for testing conditional stochastic monotonicity and investigate whether monotonicity still holds after conditioning on a number of covariates such as education, cognitive and non‐cognitive skills. Based on the NCDS cohort data from the UK, our results provide evidence that monotonicity holds, even conditionally. Moreover, we do not find large differences in our results when comparing social class and wage class mobility. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

Why was the Chinese State able to promote economic growth during the reform era, yet has been unable to do so over the previous 30 years? In this article, we focus on a specific aspect of the question, which will contribute to the development of a more comprehensive explanation: the specific institutional arrangement that may induce the autocratic government to adopt growth‐enhancing policies. We consider a standard political‐agency model (Besley, 2006) where the incumbent leader may or may not be congruent, and where, to maintain power, both leader types need the support of the selectorate, an elite group having a say in selecting the leader, as well as associated access to special privileges. Primarily, we find that in autocracies, without electoral discipline to restrain the opportunistic behaviour of a leader, the size of the selectorate should be intermediate; if it is too small, the selectorate is captured by the leader and has no disciplinary role, but if too big, the leader's incentives are diluted.  相似文献

The paper seeks to examine some of the key features of Karl Polanyi’s ideas explaining the collapse of the pre-Great Depression unregulated market system by using his broad framework of analysis, as developed in The Great Transformation and published over 70 years ago, to explain the present Eurozone crisis. Emphasis is placed on the two key institutions of the pre-Depression era, namely haute finance and the gold standard, as well as his heterodox views on the nature and origin of money to shed light on the evolving crisis within the Eurozone. On the basis of Polanyi’s insights, the paper concludes that the cause of the latter crisis is similar and it lies primarily in the adoption of stateless or supra-national money that is even more restrictive on the behaviour of national authorities than the conditions imposed under the gold standard. The current situation of quasi-permanent austerity in the Eurozone is the inevitable consequence of its monetary architecture, and it will remain a long-term feature of Europe, unless significant institutional changes are put in place to bridge the gap between money and the state.  相似文献

The aim of this work is to investigate whether the combination of forecasts plays an important role in the improvement of forecast accuracy Particular attention is paid to: (a) the methods of forecasting (the methods compared are neural networks, fuzzy logic, GARCH models, switching regime and chaotic dynamics); (b) combining the forecasts provided by the different methods. This work has also the aim of revising a short-term econometric forecast using a longer-term forecast. The revision process usually runs the opposite way (revision is made on a longer-term forecast using a short-term one to reflect the current available information, but it is not excluded that it is possible to proceed as described above. Daily data from the financial market is used. Some empirical applications on exchange and interest rates are given.  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
