Further results on the macroeconomic effects of AIDS: the dualistic, labor-surplus economy.

Analyses by Cuddington in 1993 and forthcoming work from Cuddington and Hancock model the macroeconomic effects of the AIDS epidemic using a modified Solow growth model. This single-sector framework rests upon the assumption that labor and capital are always efficiently allocated throughout the economy with neither market failures nor policy-induced distortions resulting in resource misallocation. Economies in low-income developing countries in sub-Saharan Africa, however, are not operating at capacity. Impact models based upon the potential growth path of economies will therefore significantly overstate the effect of an AIDS epidemic. The author thus incorporates the presence of underemployment and dual labor markets to redress the limitations of these earlier impact models. The dual-economy simulations of the economic impact of AIDS using Tanzanian data suggest that the macroeconomic consequences of the epidemic are of the same order of magnitude as those obtained using a single-sector, full-employment model: gross domestic product (GDP) is 15-25% smaller by 2010 than it would have been without AIDS, and per capita GDP is 0-10% smaller. Output lost from AIDS in the dual-economy framework is approximately the same as the output gain achievable through policies designed to increase labor market flexibility. Findings suggest that serious economic reform in economies fraught with AIDS may lessen the negative economic effects of the epidemic.     

Capital account liberalization, financial development and industry growth: A synthetic view

This paper synthesizes studies analyzing the effects of capital account liberalization on industry growth while controlling for financial crises, domestic financial development and the strength of institutions. We find evidence that financial openness has positive effects on the growth of financially dependent industries, although these growth-enhancing effects evaporate during financial crises. Further analysis indicates that the positive effects of capital account liberalization are limited to countries with relatively well-developed financial systems, good accounting standards, strong creditor rights and rule of law. It suggests that countries must reach a certain threshold in terms of institutional and economic development before they can expect to benefit from capital account liberalization.     

Capital Account Openness,International Trade,and Economic Growth: A Cross-Country Empirical Investigation

New empirical estimates of the effects of capital restrictions on growth support capital account liberalization, especially for developed countries. Capital restrictions reduce the benefits of foreign direct investment (FDI) on growth in developing countries. Estimation results for long-term capital flows demonstrate that countries with higher flows grow faster, challenging the belief that countries must attain a threshold level of development or human capital to benefit from capital inflows. Moreover, findings show that trade with developed countries and FDI inflows are substitutes in developing countries. Overall, the results support capital account liberalization in developed and developing countries.     

社会抚养比对资本积累和经济增长的影响研究

通过世代交叠模型和内生经济增长理论,将人力资本投资和储蓄内生化,考察社会抚养比对资本积累和经济增长的影响,并利用我国1994~2012年的省级面板数据进行实证检验。结果表明：我国少儿抚养比增加促进人力资本积累进而促进经济增长的作用小于其抑制物质资本积累进而阻碍经济增长的作用;老年抚养比的增加先后“阻碍-促进-阻碍”了我国的经济增长;总抚养比与我国的经济增长负相关。     

环境税率、双重红利与经济增长

本文构建了一个包含环境税、污染存量和预期寿命的世代交替模型,研究环境税对环境红利和经济发展红利的影响。基于新古典增长模型的研究表明,环境税能够实现双重红利(环境红利和经济发展红利),这契合“绿水青山就是金山银山”的绿色发展理念。从传导机制看,环境税通过负收入效应使得资本积累下降,同时,环境税通过健康效应使得预期寿命延长,这又使得资本积累增加。环境税通过影响资本积累,进而影响环境质量和经济发展。此外,环境税率上升使得用于环境治理的政府支出增加,这使得经济更容易产生环境红利。基于内生增长框架的分析表明,环境税有助于摆脱“环境贫困陷阱”,这为解释国家之间的收入差距提供了一个参考机制。数值模拟结果显示,在新古典增长框架和内生增长框架下,均存在最优的环境税率可以极大化人均产出和经济增长率。本文认为,合理的环境税率有助于推进减污降碳协同治理。     

基础设施投资、教育支出与经济增长——基础设施投资“挤出效应”的实证分析

把基础设施投资和教育支出放入到理论模型中进行分析,得出基础设施投资和教育支出影响经济增长的理论假定,来判断我国基础设施投资是否存在对人力资本积累的"挤出效应",以及这个"挤出效应"是否阻碍经济持续有效增长;利用1980～2010年的数据通过误差修正模型进行验证,实证结果显示:基础设施投资已经对人力资本积累产生了"挤出效应";人力资本投资显示出比基础设施投资更强的对经济增长的推动力;基础设施投资对经济的影响存在明显的地区差异性。     

The real impact of ratings-based capital rules on the finance-growth nexus

We investigate whether ratings-based capital regulation has affected the finance-growth nexus via a foreign credit channel. Using quarterly data on short to medium term real GDP growth and cross-border bank lending flows from G-10 countries to 67 recipient countries, we find that since the implementation of Basel 2 capital rules, risk weight reductions mapped to sovereign credit rating upgrades have stimulated short-term economic growth in investment grade recipients but hampered growth in non-investment grade recipients. The impact of these rating upgrades is strongest in the first year and then reverses from the third year and onwards. On the other hand, there is a consistent and lasting negative impact of risk weight increases due to rating downgrades across all recipient countries. The adverse effects of ratings-based capital regulation on foreign bank credit supply and economic growth are compounded in countries with more corruption and less competitive banking sectors and are attenuated with greater political stability.     

金融发展、汇改最优次序与长期经济增长--基于118个经济体的面板模型的分析

本文构建由金融发展、资本开放、汇率制度与产出增长组成的理论模型,选取世界上118个经济体1972-2016年的宏观数据,综合运用动态面板、面板门槛与面板IV模型进行实证分析。本文得出主要结论为:第一,在汇率制度弹性对长期经济增长的边际影响中,金融发展水平呈显著为正的调节效应;第二,对于金融发展水平较高的国家,汇率制度弹性在资本项目开放度与长期经济增长之间存在显著正向的调节效应;第三,在金融发展水平较高时,对外贸易开放度在汇率制度弹性与长期经济增长之间存在显著为正的中介效应。借鉴历史发展经验,本文归纳出"先发展国内金融市场,再开放浮动汇率,最后加强资本开放"的汇改最优次序,为我国克服汇率制度改革难点、推进资本项目开放、维持经济基本面稳定增长提出合理化政策建议。     

不同资本账户开放程度下汇率波动对经济增长的非线性效应--基于面板门限模型的分析

文章利用50个国家1997~2015年的年度数据,基于面板门限模型分析了不同资本账户开放度下汇率波动与经济增长之间的非线性效应。研究发现:第一,汇率波动与经济增长之间存在门限效应,具体表现为低汇率波动促进经济增长,高汇率波动抑制经济增长;第二,资本账户开放能够弱化汇率波动对经济增长的不利影响,且不同资本账户开放度存在异质性;第三,不同汇率波动幅度下,汇率波动与资本账户开放度的交互项对经济增长的影响存在门限效应。     

Sustainable economic growth in the European Union: The role of ICT,venture capital,and innovation

Over the past 30 years, the economies in Europe have undergone major transformations that have been powered by diffusion of information and communication technology (ICT), intensification of innovation, and reforms in the financial sector to support innovative endeavors. The primary objective of this study was to examine the causal relationships among ICT diffusion, innovation diffusion, venture capital investment, and economic growth for 25 countries in Europe for the period from 1989 to 2016. Using a vector error‐correction model, the study examines the underlying short‐run and long‐run relationships for the above variables. The empirical analysis shows that in the long run, venture capital investment, ICT diffusion, and innovation diffusion have significant impacts on economic growth in Europe. However, in the short run, the direction of the causality varies depending on the specific measures of ICT diffusion and innovation diffusion that are utilized. Results from this study provide valuable insights into the types of policies that will contribute to sustainable economic growth in Europe.     

中国资本产出、资本回报与资本流向之谜--基于劳动力价格扭曲视角北大核心

本文通过建立生产部门的要素买方垄断市场均衡模型,利用1996-2016年中国省级面板数据测算中国劳动力价格扭曲程度,并使用固定效应模型(FE)及面板固定效应的工具变量(IV)估计方法加以分析,从劳动力价格扭曲视角解答了中国资本产出、资本回报与资本流向之谜,即中国经济如何在赶超阶段面临资本深化不断加剧和TFP增长乏力的情况下,依靠劳动力价格扭曲实现低资本产出与高资本回报水平共存,从而维持长期高速资本积累以及优质的资本流向结构。实证研究表明:劳动力价格扭曲降低了资本产出效率,但这并不能掩盖由劳动力向资本方转移的垄断利润对资本回报的直接补贴,因此劳动力价格扭曲对中国维持高资本回报水平起到了重要的支撑作用,并通过高资本回报水平实现了地区资本快速积累,劳动力价格扭曲对资本流向的积极作用还体现在抑制资本"脱实向虚"及吸引外资流入。因此,应正视劳动力价格扭曲在赶超阶段的特殊作用,在矫正扭曲的过程中循序渐进,更积极采取措施规避其对资本回报和资本流向可能产生的不利影响。     

亚洲新兴经济体国际资本流动驱动因素研究——基于GMM模型的实证分析

理解资本流入的驱动因素,对于设计一个有效的资本流动管理政策框架至关重要。本文研究了1998年至2018年间45个新兴经济体面临的各类资本流动的驱动因素,重点分析了资本流向亚洲地区的驱动因素与其他地区的共性和异质性。使用广义矩估计方法(GMM)对面板数据集的实证结果表明,对新兴经济体而言,制度质量和国内因素对吸引资本流入具有重要影响;对亚洲地区来说,人均收入增长和贸易开放是吸引资本流入的重要驱动因素,国内外利差水平和实际有效汇率变动对吸引组合投资和其他投资具有显著影响,VIX指数和影子利率对亚洲新兴经济体资本流动规模的影响也具有重要影响。这表明,在设计管理资本流入的政策框架时,全球经济金融合作和政策协调应被考虑在内。     

Bank capital and economic activity

Banks argue that holding higher capital will have adverse implications on their lending activities and thereby on economic growth. Yet, the effect of a stronger capital base on economic growth remains largely unsettled. We argue that better capitalized banks improve financial stability conditions and, in dire times, they are able to sustain credit to the economy thereby containing adverse macroeconomic implications. Using various methods, we test for the presence and strength of a financial stability channel and a bank lending channel by drawing evidence from 47 advanced and developing countries over close to two decades. We find that higher capital ratios improve financial stability and help sustain bank lending, ultimately exerting a positive influence on economic activity. These effects on real GDP growth are economically significant, reaching up to 1¼ percentage points for each percentage point acceleration in capital. Our main results are robust to various sensitivity checks, supporting the conclusion that safer banking systems do not bridle economic activity.     

Economic Growth and Inequality: Why It Matters and What's Coming Next

This article makes the case that the recent rise in income inequality in OECD countries reflects profound changes in the economic model that previously resulted in growth, prosperity, and social progress during the second half of the last century. The author begins by citing French economist Thomas Piketty's identification of the key driver of rising income inequality as the recent sharp increase in the share of national income going to capital (defined as interest, dividends and other investment returns) and the accompanying decline in the share going to labor (in the form of wages, salaries, pension, and other work‐related benefits). For most of the last 100 years, a successful balance was struck in a majority of OECD countries between the returns to capital and labor. Within the framework of nationally defined economies, labor could effectively advocate for its share of the productivity gains by capital, and governments had the ability to constrain the free movement of capital, set labor compensation standards, and redistribute income through progressive taxation. The author explores how two developments—globalization and the rise of machine intelligence—are disrupting this social contract and reshaping our economy and society. The combination of these two developments, by accelerating the flow of income to capital and away from labor, is eroding the historical relationship between capital, labor, and governments that has long prevailed in most OECD countries. As this happens, we are seeing rising income inequality and the erosion of the middle class, which had been the driver of economic growth for most of the past century. Indeed, the thesis of Piketty's book, Capital in the Twenty‐First Century, is that such an effect may well be taking us back to the pre‐20th century norm of high income inequality and low economic growth. In his closing arguments, the author suggests that avoiding this scenario will be more complicated than simply raising taxes on capital, as proposed by Piketty. It may well require a fundamental rethinking of the role of employment as the primary mechanism for income distribution in society and how we prepare our workforce for an economy and society in which the concept of work will be radically redefined.     

Corporate Transparency, Financial Development and the Allocation of Capital: Empirical Evidence

There is controversy regarding the role of financial development in promoting economic growth. Lucas (1988 ) suggests that the role of financial intermediation in economic growth has been very badly over-stressed in the popular and professional discussion. Levine et al . (2000 ), on the other hand, show that in a cross-country setting the exogenous component of financial intermediary development is positively and robustly linked to economic growth. Although empirical methodologies to investigate the finance-growth nexus have been refined, there is a lack of understanding about the exact mechanisms through which the financial system could affect economic performance in the real sector. Wurgler (2000 ) investigates one such mechanism of economic growth: whether capital is allocated efficiently. He then empirically shows that countries with well-developed financial architecture improve capital allocation. This article extends Wurgler (2000 ) by investigating the role of an important economic institution, the financial reporting system, on the efficiency of capital allocation. Financial reporting provides the primary source of independently verified information to the capital providers about the performance of managers and facilitates efficient resource allocation decisions. Results show that financial transparency is positively and significantly related to capital allocation efficiency. Further, this result holds after controlling for the impact of stock price synchronicity, state-owned enterprises and investor protection rights.     

Global uncertainties and portfolio flow dynamics of the BRICS countries

This paper investigates the dynamics of bond and stock market capital flows to BRICS countries under uncertainties such as global economic policy uncertainty and the US trade policy uncertainty. We use a time-varying Granger causality framework over the January 2008-November 2019 period to analyze the predictive power of uncertainties on capital flows in the form of bond and equity. The results show that the effects are heterogeneous across countries and stronger during the Global Financial Crisis period and post-2018 period while it lost its significance in the subsequent period. The negative influence of uncertainties on capital flows directed to BRICS countries is also evident in the results of non-parametric time-varying panel models. Overall, it is thought that the heterogeneous structure of the causality between uncertainty and portfolio flows into BRICS may present portfolio diversification benefits for global investors.     

人口老龄化、养老保险基金缺口弥补与经济增长

本文构建一个包含财政支出和公共债务的世代交叠模型,以养老保险基金缺口弥补为核心内容,考察人口老龄化对经济增长的影响,并探讨采用何种基金缺口弥补方式更有利于促进经济增长。研究发现,若采用财政补贴方式弥补基金缺口,生存概率上升和生育率下降均提高经济增速;若采用发行公债方式或两者兼用方式弥补基金缺口,当人力资本产出弹性较小时相应结论不变,反之则经济增速随生存概率上升呈倒U型变化趋势,随生育率下降而提高。基金缺口弥补方式是影响经济增长的重要制度因素,人力资本产出弹性较小时发行公债方式下的经济增速最高,反之则为财政补贴方式。结合我国现实,本文认为政府应探索包括发行公债在内的多种基金缺口弥补方式以更好地应对人口老龄化,实现经济长期较快增长。     

Hot Money and Business Cycle Volatility: Evidence from Selected ASEAN Countries

This study investigates the linkage between speculative capital and business cycles in Malaysia, Thailand, and Singapore from 1981:Q1 to 2012:Q4. We use the multivariate Markov-switching intercept autoregressive heteroskedasticity vector autoregressive (MSIAH-VAR) model and observe that while speculative shocks during the tranquil period temporarily promoted Malaysia’s economic growth, they temporarily damaged economic growth in Thailand and Singapore. Moreover, speculative capital flows from abroad exacerbated economic volatility and damaged economic growth prospects for all these countries during the crisis period. Thus, it may be important for policymakers to take appropriate actions against the potential risk of economic instability and market volatility from speculative capital.     

金融政策与经济低碳转型——基于增长视角的研究

在“碳中和”目标背景下,本文基于经济“增长”视角,从理论上分析金融政策在经济低碳转型中能够发挥的作用。我们构建了一个包含清洁(绿色)与非清洁(非绿色)生产部门、定向技术进步、金融约束与金融政策的内生增长模型。通过基于模型的理论证明与数值模拟,我们发现:(1)清洁部门相对非清洁部门更强的金融约束会推迟经济低碳转型过程、导致环境恶化,绿色金融政策能够缓解清洁部门的金融约束。(2)绿色金融政策能够增加清洁部门的产量,在一定条件下,还能促进经济实现低碳转型并阻止环境恶化。(3)通过金融政策推动经济低碳转型,相比部分财政政策具有成本效益优势;两类政策存在组合搭配的空间。(4)在疫情冲击后加大绿色金融政策力度,将有益于实现“绿色复苏”,并有可能以相对平时更低的成本,加快“碳达峰”与经济低碳转型的进程。     

Bridging the Gaps: Credits,Adoption, and Inequality

We examine here the role of credits on technology adoption and inequality from the perspective of developing countries. Utilizing a model of exogenous growth, with heterogeneous labor and technical progress embodied in physical capital, we find that credits can contribute to a faster adoption and to reducing income inequality. Thus, a virtuous cycle of credits, a shorter technological gap, less inequality, and economic growth is feasible to be created when there is full liquidity in the market. When credits are constrained, the cycle loses virtuosity, where the economy can lose up to two points in growth due to credit constraints.
