International migration and the welfare state revisited

Immigration is a controversial topic in most developed economies. The presence of a redistributive welfare state in all major immigrant host countries creates a margin on which immigration affects native welfare. The primary focus of the paper is whether a large intake of immigrants reduces welfare state effort. It is usually argued that steady increases in immigration lead to public pressure for lower levels of publicly-funded social expenditures. In contrastz to the earlier empirical literature on this topic, we find little evidence in favour of this hypothesis. While immigration does have a relatively modest effect on the welfare state, if anything there is some support for the view that a greater influx of immigrants has lead policy-makers to increase welfare state spending.     

农村公共品建设意愿一致性研究 ——基于我国“十县百村”的实证分析

本文利用“十县百村”的大样本调研数据研究农村公共品建设意愿的一致性问题。统计分析表明,农户最需要的三类公共品分别是乡村道路、灌溉设施和农村社会保障。通过对比村级和农户的公共品建设意愿发现,农村公共品建设的一致性程度很低。进而本文采用多元logit分析和线性回归分析得出影响一致性的因素有：性别、是否党员、是否从事农业生产、人均土地面积、是否是新农村示范村、村长是否选举、村级公共开支总额。本文最后提出了相关的政策建议。     

More for everyone: The effect of local interests on spending on infrastructure

A central question in political economy is whether decision-making in representative democracies is biased towards local public investments or other types of policies which have locally concentrated benefits. The model by Weingast et al. (1981) predicts that a legislature with members from different areas will spend more in total on local public goods when the geographic constituency of each member is small. I test this prediction using panel data on the 18 Norwegian regional councils, exploiting that the geographic allocation of regional council seats varies considerably over time. Consistent with the theory, I find robust evidence that investments in regional public roads are lower when many council members come from the more populated areas in the region. This gives a more direct test of the prediction by Weingast et al. (1981) than existing empirical evidence, which concerns the relationship between public spending and legislature size. I find similar but less robust results for the maintenance of existing roads.     

On the Neutrality of Redistribution in a General Equilibrium Model with Public Goods

Models on private provision of public goods typically involve a single private good and linear production technology for the public good. We study a model with several private goods and nonlinear (strictly concave) production technology. We revisit the question of „neutrality” of government interventions on equilibrium outcomes and show that relative price effects that are absent with a single private good and linear production technology become a powerful channel of redistribution in this case. Contrary to previous results, redistributing endowments in favor of contributors is shown to be neither necessary nor sufficient for increasing the equilibrium level of public good.     

The Spatial Range of Public Goods Revealed Through Referendum Voting

Billions of dollars are now spent annually in the United States and Europe for spatially delineated environmental services such as agricultural landscape management and river restoration programs, yet little is known about the spatial distribution of the benefits from these policies. This paper develops a framework for recovering information on this question from the spatial pattern of votes cast for referenda on the provision of spatially delineated public goods. We specify a model linking voter support for environmental improvement to the distance at which such improvements are expected to occur. The empirical application is to a river restoration referendum in the Swiss canton of Bern. Our results indicate that the benefits from river restoration have a strong local component, sufficiently strong that voter approval would not occur if only canton-wide benefits were at stake. Surprisingly, support for river restoration is no greater, and in some specifications is actually lower, in locations where rivers are a prominent feature in the environment.     

Equilibrium among local jurisdictions: toward an integrated treatment of voting and residential choice

In models of local public goods with mobile consumers, existence of equilibrium is problematic. Difficulties with existence of equilibrium that arise in models with discrete locations and in models with voting are compounded when both features are introduced into the same model. We present conditions under which equilibrium exists in a model where freely mobile households choose community of residence and amount of housing consumption, and vote on the level of public goods provision. These conditions involve restrictions on preferences and the technology of public goods supply. At least some of these conditions appear consistent with empirical observations. We discuss the implications of the conditions, and their role in assuring existence of equilibrium. A series of computational examples provide illustrations of the way these conditions interact, and the difficulties that must be confronted if they are to be relaxed.

Chasing votes with the public budget

This paper examines the distribution of public resources by an incumbent seeking re-election. I present a model to explain the behavior of an incumbent redistributing public goods and cash transfers. According to the model, politicians use the government budget as a portfolio for electoral investment and diversify expenditure in order to target different groups of voters at the same time. I construct a unique data set of the promises made by the president of Colombia from 2002 to 2010 to municipalities throughout the country's various regions. The empirical results show some evidence that promises of cash transfers targeted swing voters, promises of public goods simultaneously targeted both core and swing municipalities, while opposition municipalities received few promises of cash transfers and public goods, which is consistent with the prediction of the model.     

中国农村社区公共物品投资的决定因素分析

本文使用具有全国代表性的抽样调查数据,对农村社区公共物品投资的决定因素进行了初步的分析。本文通过理论分析提出了两个理论假说,进而提出在我国公共投资中要注意的问题:既要考虑各地对公共投资有不同的需求,还要考虑区域协调发展。研究结果表明,除了一些政策因素以外,当地经济发展水平是影响农村公共投资的重要因素,一般来说,在工商业较发达的村公共投资活动也相对较多。对于外出务工人员较多的村,由于本地公共投资对外出务工人员的收入等作用较小,因此这部分村民就不那么愿意对村里进行公共投资。从政策实施角度看,本研究发现,上级政府的公共投资更多地投向贫困地区、偏远山区、农业生产条件差的地区或少数民族地区。这种投资战略有助于统筹区域发展,降低区域差异。

Protesting and Justifying: A Latent Class Model for Contingent Valuation with Attitudinal Data

This article develops a latent class model for estimating willingness-to-pay (WTP) for public goods using simultaneously contingent valuation (CV) and attitudinal data to identify individuals with similar characteristics, such as WTP and protest attitudes. We find evidence that the answer to the CV question influences the responses to the attitudinal questions. In our case, this influence reflects rational behavior (budget constraint issues) and justification biases related to protest reasons, such as lack of trust in institutions or fairness issues with respect to the distribution of the burden of preservation. The results from our empirical application confirm the importance of accounting for those biases.     

Growth Effects of Fiscal Policy and Debt Sustainability in the EU

In this paper we study the relationship of fiscal policy and economicperformance of some core countries in the EU. Our aim is to find outwhether public deficit and public debt have consequences for real variables in the economies we consider. The background of our empirical study is a growth model that provides us with some predictions on the relationship between fiscal policy and economic growth. In a first step we then use Granger causality tests to analyze empirically whether some of the implications of our model arecompatible with the data. In a second step, we investigate whether the fiscalpolicies of the member states have been sustainable. Given this information,we then pursue the question of whether differences in the fiscal positions ofcountries have consequences as concerns the outcome of our empirical testsof step one. Finally, we study whether the impact of the public deficit ratiodepends on the magnitude of the debt ratio.     

消费者自愿在线反馈行为的效用分析——基于马斯洛人类动机理论的考察

自愿的在线反馈行为是网络消费中的普遍现象，其背后隐藏着一个重要的经济学问题，即公共品的私人自愿供给。为了更深入地研究消费者自愿进行在线反馈的动因，并相应探讨私人自愿提供公共品的原因，本文以马斯洛人类动机理论为基础，建立了自愿在线反馈行为的效用模型，并利用网络问卷数据对模型进行验证。研究结果表明，自愿在线反馈行为是消费者在效用和成本之间理性选择的结果，公共品的私人自愿供给方式具有理性基础。本文拓展了传统效用函数的内涵，深化了对公共品私人自愿供给和马斯洛动机理论的认识，也为网络消费平台的信用体系建设提供了新思路。     

Targeting public goods to the poor in a segregated economy: An empirical analysis of central mandates in rural India

While local governments are increasingly being vested with control over funds for public goods, concern over the capture of decentralized funds by local elites has led decentralization to be combined with central mandates which require a certain proportion of funds to directly benefit the poor. If local capture is pervasive, however, central mandates may not be effective. Despite the popularity of this combination of decentralization and centralized control, there is little empirical evidence which separately identifies their effect on investment in public goods, and hence assesses the effectiveness of central mandates. This paper provides such evidence, using data collected by the authors for the North Indian state of Punjab, an economy where economic conditions facilitate such an analysis. We find that central mandates are effective, enhancing intra-village equality in expenditure on public goods. This finding informs the debate on the equity effects of centralized versus decentralized programs.     

Demand for different types of public goods: evidence from Nigeria

Preferences of Nigerian households vary across different types of public goods. For example, some prefer roads while others favor education even after controlling for the existing supply of these goods. What explains this variation? We argue that the perceived distributional consequences of specific public goods differ conditional on the personal characteristics of households. In particular, households demand the type of public good that (a) increases the utility of assets they already own and (b) resonates with their past experiences involving the lack of particular public goods. We test our argument with data on 123,000 Nigerian households. We find strong evidence for our argument across six types of public goods.     

Non-monotonic group-size effect in repeated provision of public goods

This paper analyzes the effect of a change in group size on incentives to contribute in repeated provision of pure public goods. We develop a model in which group members interact repeatedly, and might be temporarily unable to contribute to public goods production during some periods. We show that an increase in the group size generates two opposite effects – the standard free-riding effect that suppresses cooperation, and the novel large-scale effect that enhances cooperation. Our results indicate that the former effect dominates in relatively large groups while the latter dominates in relatively small groups. We, therefore, provide a rationale for a non-monotonic group-size effect that may explain previous empirical and experimental findings.     

The political economy of public goods: Some evidence from India

We are interested in how public goods get allocated by a centralized state. We use data on public goods and social structure from parliamentary constituencies in rural India to understand the allocation of these goods over the 1970s and 1980s. National policies and political agendas during this period emphasized universal access to basic amenities and financed a rapid expansion in rural infrastructure. We find evidence of considerable equalization in many of these facilities, reflecting perhaps the importance of these commitments. Among the historically disadvantaged social groups, those that mobilized themselves politically gained relative to the others. Measures of social heterogeneity that have been emphasized in the recent empirical literature on public goods are relevant but not overwhelming in their importance.     

分权体制下的民主参与、政府响应程度和公共品供需偏差

文章考察了当前背景下政府对地方民众公共品需求偏好的响应能力,利用1998～2008年期间的公共支出样本值测算了中国地方公共支出偏差指数,并引入不同选区人大代表指标作为民主参与的工具变量,以此体现政府响应能力。实证结果发现,财政分权、民主参与和公共品供需偏差三个变量之间存在着显著的内生关联;分权体制导致了政府公共品供给扭曲,而民主参与则部分抵消了公共品供需偏差。     

Property values,local public expenditure and economic efficiency

A bid-rent model of property value determination with a public good and property taxation is developed. Using the local government budget constraint, an estimating equation is derived which can indicate whether public goods are efficiently provided. The empirical results show over-provision of public goods in northeastern New Jersey.
