GOVERNMENT SIZE AND GROWTH: A SURVEY AND INTERPRETATION OF THE EVIDENCE

Abstract The literature on the relationship between the size of government and economic growth is full of seemingly contradictory findings. This conflict is largely explained by variations in definitions and the countries studied. An alternative approach – of limiting the focus to studies of the relationship in rich countries, measuring government size as total taxes or total expenditure relative to GDP and relying on panel data estimations with variation over time – reveals a more consistent picture. The most recent studies find a significant negative correlation: an increase in government size by 10 percentage points is associated with a 0.5% to 1% lower annual growth rate. We discuss efforts to make sense of this correlation, and note several pitfalls involved in giving it a causal interpretation. Against this background, we discuss two explanations of why several countries with high taxes seem able to enjoy above average growth. One hypothesis is that countries with higher social trust levels are able to develop larger government sectors without harming the economy. Another explanation is that countries with large governments compensate for high taxes and spending by implementing market‐friendly policies in other areas. Both explanations are supported by ongoing research.     

政府债务对经济增长的影响及作用渠道

基于1960～2010年113个国家的面板数据集,运用系统广义矩动态面板方法和稳健性分析,比较发达国家和发展中国家政府债务经济增长效应的差异,并尝试分析政府债务影响经济增长的渠道。研究结果显示,政府债务对经济增长有非线性影响;发达国家政府债务对经济增长、投资以及全要素生产率均无显著影响;发展中国家对政府债务的直接承受力更弱,但在一个宽松的临界点内,政府债务的增加可以提高投资率。     

政府规模、政府支出增长与经济增长关系的非线性研究

本文运用面板平滑转换回归模型(PSTR),在非线性的框架下对政府规模与经济增长关系的渐进演变展开深入研究,并对可能引发两者关系结构性转变的警戒政府规模进行有效估算。研究结果表明,政府规模与经济增长之间存在着非线性关系,即随着政府规模的逐步增大,由于税负增加等因素的影响,使得政府支出增加所产生的负效应影响逐步凸显,而政府规模进一步扩大并超过警戒水平时,过度拥挤的政府支出对经济增长将由促进作用转变为阻碍作用。研究还发现,尽管我国政府支出增长与经济增长的关系参数值有所下降,但由于基础设施落后,公共物品与公共服务供给仍然相对不足,政府支出的增加仍有助于促进经济的进一步发展。     

GOVERNMENT SIZE AND GROWTH: A SURVEY AND INTERPRETATION OF THE EVIDENCE – A COMMENT

In contrast to the commonly held view, Bergh and Henrekson (2011) conclude that a consensus has almost been reached on the thesis that government size is negatively correlated with economic growth in developed countries. They underpin this by claiming that the only study in the survey to deviate from this consensus view, i.e. Colombier (2009), was rebutted by Bergh and Öhrn (2011). This comment shows that the claim by Bergh and Henrekson (2011) cannot be upheld because the analysis by Bergh and Öhrn (2011) is based on a flawed dataset. The re‐estimation of Colombier's (2009) regressions with time‐fixed effect does not reject his main findings. Moreover, it is demonstrated that recent empirical evidence on the growth impact of government size in rich countries is not as unanimous as the survey by Bergh and Henrekson (2011) suggests. Thus, the claim that a consensus view has been reached is premature.     

PRODUCTIVE GOVERNMENT EXPENDITURE AND ECONOMIC GROWTH

Abstract.  We provide a comprehensive survey of the recent literature on the link between productive government expenditure and economic growth. We show that an understanding of the core results and the ensuing contributions can be gained from the study of their respective Euler equations. We argue that the existing literature incorporates many relevant aspects; however, policy recommendations tend to hinge on several knife-edge assumptions. Therefore, future research ought to focus more on idea-based endogenous growth models to check the robustness of policy recommendations. Moreover, the inclusion of hitherto unexplored types of government expenditure, e.g. on the 'rule of law', would be desirable.     

债务率、偿债压力与地方债务的经济增长效应

研究目标：中国地方政府债务对于经济增长的门限效应。研究方法：基于债务率,即债务存量与地方政府综合财力的比值的视角,利用中国30个省份2010~2014年年底的地方债务余额数据,对地方债务的经济增长效应进行了实证研究。研究发现：中国地方债务存在明显的经济增长门限效应：当债务率高于112%左右之后,原本正向显著的经济增长促进作用基本趋近于无,而其作用渠道可以明确为如下传导机制,债务率高企带来地方政府偿债压力从而影响经济发展导向的财政支出。研究创新：引入债务率指标并基于偿债压力视角分析了地方债务对于经济增长的作用机制。研究价值：对于我国地方政府债务的管控治理和风险防范,具有重要的参考价值。     

On the role of policy interventions in structural change and economic development: The case of postwar Japan

In this paper, we study the structural change occurring in Japan's post-World War II era of rapid economic growth. We use a two-sector neoclassical growth model with government policies to analyze the evolution of the Japanese economy in this period and to assess the role of such policies. Our model is able to replicate the empirical behavior of the main macroeconomic variables. Three findings emerge from our analysis. First, neither price and investment subsidies to the agricultural sector, nor industrial policy plays a crucial role in the rapid postwar growth. Second, had there existed a labor migration barrier, the negative long-run level effect on output would have been substantial. Finally, TFP in non-agricultural sector is mostly responsible for the rapid growth of Japan in the post-war period.     

The impact of fiscal positions on government bond yields in CEE countries

This paper investigates the influence of government debt and primary balance on long-term government bond yields in 10 Central and Eastern European (CEE) countries in the period 2000–2013. The results indicate that a one percentage point increase in the stock of government debt is associated with an increase in government bond yields of 2.7–4 basis points, while a one percentage point increase in the primary deficit to GDP ratio is associated with an increase in government bond yields of 12.9–24.3 basis points. We also find evidence of non-linearities in the debt-interest rate relationship, whereby the threshold after which the impact of debt turns from negative to positive is significantly lower than in advanced economies.     

Government intervention in European mergers and acquisitions

The increasing globalization of economies has leveraged protectionist attitudes in different countries during the last decades. In the context of cross-border mergers and acquisitions (M&A), national governments have intervened to “protect” big domestic firms and their industries from foreign bidders. Despite the potential for severe implications of these actions on the internationalization of firms and development of markets, the research in this area is relatively scarce, and we still know very little about the real causes and consequences of government intervention. In this paper, we study government opposition to cross-border European M&A during the period 1997–2017, an era of important changes in Europe. Using an event study methodology, we examine abnormal returns for targets and their rivals in the time period prior to actual intervention to gauge if investors perceive intervened deals as harmful events for the industry, which could justify government intervention. We use a hand collected sample of 1,574 EU15 rival firms for 48 mergers, of which 18 experience government intervention. Entropy balanced regression models show that rivals of intervened targets earn significantly lower returns relative to rivals of non-intervened targets on deal announcement. Nevertheless, rivals’ abnormal returns are not negative, suggesting that intervened deals are not perceived ex ante as harmful for industry competitiveness. The results are more consistent with investors’ ability to identify likely blocked deals, which puts downward pressure on abnormal returns to both the target companies and their rivals. These findings indicate that government interventions against foreign bidders seem to have an economic cost in the sector that is anticipated by the investors.     

注册会计师的角色认识与监管中的难题思考

从审计市场的供需两方来看,作为以提供审计服务换取收入的注册会计师,不可避免地有着“经济人”的共有特征——追求自身利益最大化,但同时,由于需求方信息使用者的广泛性,注册会计师实际上又肩负着维持市场秩序的社会责任,这正是注册会计师比其他提供劳务的行业受到更多限制的原因所在。从中关独立审计的发展轨迹可见,为了使注册会计师担当好其应有的社会角色,单靠市场或政府都是不可行的,作为公众利益的代言人——政府,如何合理把握市场与政府的界限,做好市场主体权利的配置是各国政府共同面临的难题。     

Regional Disparities and Government Quality: Redistributive Conflict Crowds Out Good Government

Abstract

In this paper, we argue and provide empirical evidence to support the claim that higher income differences across regions increase the salience of interregional redistribution and, as a result, crowd out policies aiming towards improvements in government quality or efficiency. In the presence of greater regional disparities, the balance of politics may tilt towards redistributive concerns and away from government efficiency considerations, especially since the latter can be opposed by organized public sector interest groups. Our empirical analysis, based on a sample of 22 Organization for Economic Co-operation and Development (OECD) countries over the period from the mid-1990s to 2005, supports our basic intuition that regional disparities may lead to territorially based redistributive conflict to the detriment of government quality.     

Long-run and short-run determinants of sovereign bond yields in advanced economies

We analyze determinants of sovereign bond yields in 22 advanced economies over the 1980–2010 period using panel cointegration techniques. The application of the cointegration methodology allows distinguishing between long-run (debt-to-GDP ratio, potential growth) and short-run (inflation, short-term interest rates, etc.) determinants of sovereign borrowing costs. We find that in the long run, government bond yields increase by about 2 basis points in response to a 1 percentage point increase in government debt-to-GDP ratio and by about 45 basis points in response to a 1 percentage point increase in the potential growth rate. In the short run, sovereign bond yields deviate from the level determined by the long-run fundamentals, but about half of the deviation adjusts in one year. When considering the impact of the global financial crisis on sovereign borrowing costs in euro area countries, the estimations suggest that spreads against Germany in some European periphery countries exceeded the level determined by fundamentals in the aftermath of the crisis, while some North European countries have benefited from “safe-haven” flows.     

Two faces of corporate lobbying: Evidence from the pharmaceutical industry

In this study, we examine how political connections increase firms’ innovation performance. By examining firm-level lobbying activities, we find that political connections lead to a greater number of medical breakthroughs among pharmaceutical firms in our sample. We then examine the underlying ways that political connections enhance innovation among medical firms. Using hand-collected data on government subsidies, we find that politically connected firms have a higher chance of receiving subsidies from federal, state, or local government agencies. These government subsidies enhance medical innovation by insulating managers from short-term threats and mitigate their career concerns by creating a “failure tolerant” environment. Overall, we show that connections between firms and politicians come with increased innovation outcomes.     

是市场的功能还是政府的作用——从传统、转型期经济向现代市场经济过渡

我们把发展中国家和经济转型期国家经过市场参数变换的区域称之为复通经济区域。本文从理论上揭示出在这些区域向现代市场经济过渡的时期必然存在着经济的零增长阶段,在此阶段如果政府无作用或作用不当,通货膨胀、贫富差距拉大和社会动荡等现象是不可避免的,这种现象从拉美等经济转型期国家的经验数据得到了验证。本文在此基础上以中国经济转型期的经验数据和实践基础论证了政府作用于市场经济的基本原理和方法,进而通过中国经济平稳增长过渡的"路径依赖"说明了中国经济改革和发展的科学性和正确性。     

How Large Is International Trade’s Effect on Economic Growth?

The estimated static welfare gains from international trade are very small, on the order of one percent of GDP. The case for free trade is therefore increasingly linked to trade’s apparent positive effects on economic growth. But how large are these growth effects? The vast empirical literature has emphasized the statistical significance, not the economic significance, of the trade‐growth relationship. This survey’s re‐examination of the empirical literature focuses on the size of the relationship between trade and growth. Our survey reveals that the many empirical studies are surprisingly consistent in terms of the size of the relationship: A one percentage point increase in the growth of exports is associated with a one‐fifth percentage point increase in economic growth. Given the power of compounding, the effect of trade on growth is very important for human welfare.     

国债投资的利率风险免疫研究

亚洲金融危机后，我国国债发行和交易利率逐步下降，国债投资收益率也随之下降。但是，目前我国的宏观经济面临新一轮过热的压力，中央银行也面临提高利率的压力，也极大地增加了国债投资的利率风险。本文从利率期限结构承受线性冲击和非线性冲击以及随机利率期限结构条件下，利用免疫理论研究如何防范国债投资的利率风险。     

小城市基础设施经济效率的变化

长期以来,基础设施投资是我国全社会固定资产投资的重要组成部分,也是促进我国经济发展的重要动力.但是,还缺乏文献对基础设施的经济效率进行综合评价.论文以陕西关中地区小城市为例,采用DEA模型研究基础设施在促进经济增长和城市化中的效率变化.计算结果显示,从长期来看基础设施的经济效率是下降的,但是随着我国基础设施投融资体制和管理体制的改革.下降的速度得到了遇制.因此,基础设施投融资体制改革和基础设施管理体制改革可能是比基础设施投资更为重要的课题.     

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’.     

我国政府绩效审计未来发展问题研究

本文在借鉴国外相关研究成果的基础上,充分考虑我国国情,提出了我国政府绩效审计未来战略发展方向,认为我国的政治环境决定了政府绩效审计的路径选择只能是渐进式发展道路;法律环境决定了国家审计署将是绩效审计的主要推动者;经济文化环境决定了我国各地区绩效审计的开展未必完全同步,但均需大力推进;技术手段虽是开展政府绩效审计的必要条件,但并非制约我国政府绩效审计发展的主要因素。     

财政购买性支出激励与经济持续增长——兼论确立服务型政府的合理性

本文建立了政府支出创新激励经济增长的理论模型,模型表明政府支出对经济增长的效应取决于预算、投资生产率和支出结构.借助VAR实证模型,中国的经验实证分析表明:公共花费是公共投资的基础,也是GDP增长的主要影响变量;公共投资不一定能促进GDP增长.为此,我们提出政策建议:必须转变政府职能,由投资型政府变为服务型政府,以促进经济持续增长.
