Throughout much of mankind's experience with elections, vote brokers – local elites who direct the voting decisions of a subset of the electorate – have been able to make or break political careers. In various polities, brokers have thrived in spite of the secret ballot, a surprising outcome given that vote secrecy would ostensibly allow citizens to pocket the inducements offered by such individuals and vote their consciences anyway. To address this puzzle, we develop a framework for understanding the persistence and demise of vote brokerage under the secret ballot. In our model, a broker contracts with voters using an outcome contingent contract: some fixed benefit is promised to all voters sharing one of several observable profiles should the broker's candidate win the election. Using this framework, we demonstrate that the existence of brokerage depends on the size of the electorate contained within the jurisdiction controlled by the broker, with large jurisdiction sizes tending to drive brokerage out of existence. Moreover, we detail the manner in which the strategies employed by brokers depend on their economic power, the size of social groups, and ideological polarization. Empirical evidence from Minas Gerais, Brazil is used to evaluate the performance of the model.  相似文献

Conservation programs are a significant part of farm legislation. The recent farm bill increases funding of conservation programs. One result will likely be the increased adoption of basic environmentally benign farming practices, such as conservation tillage. This would lead to improvements in surface water quality. In this paper, we examine the magnitude of the nonmarket use value benefits of these improvements. The findings indicate that moderate to widespread adoption of practices such as conservation tillage would result in significant nonmarket benefits.  相似文献

We estimate a probit model of residential land conversion using parcel-level data from a rural-urban county in Ohio. Spatial landscape pattern metrics are used to quantify land-use patterns and to link patterns of residential sprawl with factors estimated to influence parcel-level land conversion. Findings indicate that the location of new residential development is influenced by preferences for lower density areas that nonetheless are close to existing urban development. Combined, these forces have generated a moderated pattern of residential sprawl. Spatial error autocorrelation is controlled using a spatial sampling technique that enables consistent estimation of the probit model.  相似文献

The purpose of this article is to model the interaction between the targets of the current Comman Agriculture Politic (CAP): environmental adaptation, subsidies, and efficiency of animal farming. To this end we first have to identify the production frontier and relative efficiency level for each animal‐oriented farm in the sample. The production frontier and efficiency index for each type of farm (assuming no specific production functions) are identified using Data Envelope Analysis (DEA) techniques. We then address the relationship between relative efficiency, farm size, and environmentally friendly behavior by carrying out a nonparametric regression of efficiency, on economic size, a proxy for the degree of environmental appropriateness, and regional dummies. Calculations of the efficiency of the farms including direct subsidies are compared with the counterfactual exercise in the case in which direct subsidies are not considered. Finally, we look for relations between subsidies and factors such as farm size, efficiency, and environmentally friendly behavior. One key result shows that, on average direct payments generally tend to increase efficiency. However, in most of the cases the mean efficiency decreases as the percentage of direct payments rises. Direct payments are found to be positively related to environmentally friendly production, at least in Germany. However, in general, the direct payment system is not sufficient to offset the fact that the less environmentally friendly farms as well as the larger farms are more efficient.  相似文献

Most of the previous studies on the firms’ debt-equity choice utilize the standard single equation Probit (or Logit) model as if firms face a single dichotomous decision to issue debt or equity, but not both. The main purpose of this study is to use a two stage Bivariate Probit–Tobit model to examine the factors affecting the choice between internal and external funding and between debt and equity as well as the size of issues. Our results indicate that the Bivariate-Probit estimation is more efficient than that of two independent Probit equations. An examination of factors that affect the choice of financing form and the size of issue support the predictions of trade-off theory. The pecking order’s prediction that, if external funding is needed, firms issue debt first and then equity finds no support in this study as firms with higher information asymmetry have propensity to issue equity rather than debt. While information asymmetry affects the choice between debt and equity, we find no evidence that it influences the size of issue.  相似文献

We explore the welfare implications of agricultural expansion in the Brazilian Amazon by comparing spatially explicit estimates of soybean rents and the value of ecosystem services. Although these estimates are generated from different datasets, models, and estimation techniques, the values are comparable, such that the value of ecosystem services is greater than soybean rents for about 61% of the total area and 24% of the area where soybean rents are positive if protected areas are well enforced. Based on the balance between the benefits and costs of conversion, failure to value ecosystem services reduces total social welfare by 7.13 billion dollars annually relative to an optimum. Policy instruments that internalize the value of ecosystem services via protected lands, land conversion taxes, conservation subsidies, or excise taxes can avoid much of this loss. Regardless of intervention regime, policy makers should be cognizant of the diminishing net benefits of converting natural ecosystems to agriculture. Realizing the final 3.8% requires the conversion of an additional 15% natural ecosystems to soybean production.  相似文献

Strengthening of the “disinterested” is key in the current economic situation (Bourdieu 1986). It can provide new values and ways of managing the markets and enterprise organizations; social enterprises are emerging as instruments to make this possible. This work studies the different traditions and analyzes social enterprises and social entrepreneurs, with particular attention to Spain. It also examines trends deriving from the new emerging models, first making an approximation of social markets: a market experience based on building a production, distribution, financing, and responsible consumption network that overcomes the limits of individual companies, engaging all the market’s economic agents. Finally, the risks and opportunities that these models present for a supportive and Social Economy are analyzed.  相似文献
