The effects of public spending externalities

We conduct a positive analysis on the effects of ‘externalities’ produced by government spending. To this effect, we estimate, using U.S. data, an RBC model with two salient features. First, we allow government consumption to directly affect the marginal utility of consumption. Second, we allow public capital to shift the productivity of private factors. We provide an identification analysis that supports the strategy adopted for estimating the parameters governing these two channels. On one hand, private and government consumption are robustly estimated to be substitute goods. Because of substitutability, labor supply reacts little to a government consumption shock, so the estimated output multiplier is much lower than in models with separabilities. On the other hand, our results point towards public investment being ‘unproductive’.     

Mitigation of diffuse water pollution from agriculture in England and China,and the scope for policy transfer

This paper evaluates the existing policy frameworks for mitigation of diffuse water pollution from agriculture (DWPA) in England and China. With reference to a conceptual model of the process of policy transfer or international lesson drawing, and possible constraints to this, it assesses whether and how China can draw lessons to improve current policy from the supra-national and national provisions of the EU and a member state that by 2016 had comprehensively implemented EU agricultural and environmental policy. DWPA is first analysed as a public policy challenge to inform specification of a generic framework for its mitigation. The current policy frameworks for mitigation of DWPA in England and China are evaluated, and their potential for improvement is assessed. A number of barriers to lesson drawing for regulation, incentive payments schemes and advice provision are diagnosed. These barriers are potentially least in relation to advice provision and its use to promote voluntary action by farmers. Given its structure and capabilities the public agricultural extension system in China is also recognised as a key resource. A focus on three policy approaches to mitigate DWPA in China is recommended: i) targeted regulation to a ‘reference level’ of large intensive livestock, and ultimately other large commercial farms; ii) strategic use of incentive payment schemes to protect water resources from DWPA; and iii) re-orientation of the ethos and modalities of operation of the extension system, informed by international lesson drawing, with the aim of rebalancing farm productivity and environmental protection.     

Limits to government debt sustainability in OECD countries

The recent euro area sovereign debt crisis has shown the importance of market reactions for the sustainability of debt in advanced economies. This paper calculates endogenous government debt limits given the markets assessment of the probability to default. The estimated primary balance reaction function to growing debt has the “fiscal fatigue” property (a loosening fiscal effort makes the primary balance insufficient to support rising debt) at high debt levels. The combination of this feature of the primary balance reaction function with the market interest rate reaction to growing debt determines the government debt limit beyond which debt cannot be rolled over. An application to OECD countries over the period 1985 – 2013 with a model-based risk-premium shows that current debt limits are high for most of the OECD thanks to particularly low risk-free interest rates. It also shows for some countries that current debt levels are not sustainable without a change in government behaviour. Most importantly, the framework illustrates the state contingent nature of debt limits and therefore the vulnerability of governments to a change in macroeconomic conditions and to market reactions. Last, computations with an estimated interest rate reaction to public debt illustrate that debt limits are lower in the euro area than in other countries because of a sharper market interest rate reaction to rising debt.     

Anticipatory policymaking in global venues: Policy change,adaptation, and the UNFCCC

The subfield of public policy depicts policymaking as reactive process wherein public officials respond to existing social problems. While this depiction holds true in many cases, it fails to account for instances where policy change occurs in anticipation of emerging threats or hazards. “Anticipatory problems” are projected to occur in the future, and it is the prospect of their occurring that generates policy debate. This paper examines the policymaking pattern engendered by anticipatory policy problems, highlighting the ways in which they challenge and support existing assumptions about the process of policy change. To illustrate this distinctive dynamic, this paper will present a case study examining the evolving debate over climate change adaptation policy within United Nations Framework Convention on Climate Change (UNFCCC).     

要素禀赋、政策支持与金融资源配置:产业转移的承接模式研究

本文以商务部认定的湖南、江西省四个加工贸易梯度转移重点承接地为样本,对比分析要素禀赋、政策支持和金融资源配置的异同及其影响,在总结归纳各自承接模式的特点的基础上,提出了"精品园区+核心企业+直接融资+金融助推"的较优模式,认为政策支持是影响承接产业转移的直接因素;要素禀赋的影响力有弱化趋势;金融资源配置是影响承接力和产业结构优化升级的重要因素;对待处于不同生命周期的产业转移企业,承接的工作重点应各有侧重.因此,承接产业转移要与"转方式、调结构"的战略方向一致.注重与本地的产业互补相结合,并需要金融部门的主动参与和服务创新.     

The 2009 Recovery Act: Stimulus at the extensive and intensive labor margins

This paper studies the effect of government stimulus spending on a novel aspect of the labor market: the differential impact of spending on the total wage bill versus employment. We analyze the 2009 Recovery Act via instrumental variables using a new instrument, the spending done by federal agencies that were not instructed to target funds towards harder hit regions. We find a moderate positive effect on jobs created/saved (i.e., the “extensive margin”) and also a significant increase in wage payments to workers whose job status was safe without Recovery Act funds (i.e., the “intensive margin”). Our point estimates imply that roughly one-half of the wage payments resulting from the act were paid at the intensive margin. To provide a theoretical underpinning for the estimates, we build a micro-founded dynamic model in which a firm meets new government demand with a combination of new hiring and increasing existing workers׳ average hours. Faced with hiring costs and an overtime premium, the firm responds by increasing hours along both margins. Our model analysis also provides insight into how government spending policy should be structured to lower the cost of generating new jobs. Finally, we catalogue survey evidence from Recovery Act fund recipients that reinforces the importance of the intensive labor margin.     

CO‐INTEGRATING VAR MODELS AND ECONOMIC POLICY

This paper surveys some relevant contributions to the economic literature on co‐integrating vector autoregressive (VAR) models [vector error correction mechanisms (VECMs)], emphasizing their usefulness for economic policy. It further discusses some theoretical aspects that are necessary for a complete understanding of their potential. The theoretical introduction of the co‐integrating VAR model is followed by an illustration of its applications to monetary policy, fiscal policy and exchanges rates as well as in establishing the effects of structural bilateral shocks between countries (the so‐called global VAR, or GVAR, models). Special attention is paid to the VECM capacities of being used in conjunction with dynamic stochastic general equilibrium models and of jointly specifying the short‐ and long‐run dynamics, thus representing the steady‐state of economic systems (by means of the co‐integration relations) and the short‐run dynamics around it.     

Creating opportunities. Policies aimed at increasing openings for immigrant entrepreneurs in the Netherlands

Since the 1980s, subsequent Dutch governments have promoted self-employment of immigrants to reduce their unemployment rates. These policies have been focused on the (potential) actors themselves, i.e. the immigrants who have started or who may want to start a business. Taking mixed embeddedness as a point of departure, entrepreneurship and self-employment cannot be solely understood by focusing on the micro-level but has to include the larger macro and meso structures that impact on these actors' choices. In this paper, therefore, the focus is on the opportunity structure and on the policies that affect this set of options for starting a (small) business. A typology of policies that may alter this opportunity structure is offered.     

The impact of agricultural policy on farm income concentration: the case of regional implementation of the CAP direct payments in Italy

One of the objectives of agricultural policy worldwide concerns the support of farm income. Common Agricultural Policy direct payments (DPs) are the main instruments to support farm income in the European Union. This article addresses their role in the concentration of farm income. This is done by calculating the Gini coefficient and its disaggregation in a large sample of Italian farms in the period between 2006 and 2007. Although this approach has been used to develop ex‐post analysis in previous studies, this article is innovative given that it is used here in an ex ante analysis aimed at evaluating the likely impact of a recent reform proposal. This latter requests changing the current model to a regional model of DPs application to make payment rates (i.e., payment per hectare) homogeneous among farms in the same region. The analysis shows that DPs and farm incomes are both very concentrated but that DPs allow for an income concentration reduction in Italian farms. The shift to a regional implementation reduces DPs concentration and, to a limited extent, farm income concentration. Of the considered regionalization scenarios, those that redistribute DPs among regions are the most effective in reducing concentration. The extension of the Gini considered approach to an ex ante setting seems effective because it provides insights that could feed the policy debate regarding the forthcoming reform.
