OPTIMAL DEBT AND ENDOGENOUS GROWTH IN MODELS OF INTERNATIONAL FINANCE

The International Monetary Fund, the World Bank and the bond rating agencies did not anticipate the crises in Asia 1997–98 and in Argentina 2001 . With this statement in mind, we consider some multi-stage inter-temporal stochastic optimisation models in international finance that imply theoretically founded and empirically measurable Early Warning Signals. The mathematical technique is dynamic programming/stochastic optimal control (DP/SOC).
The variables of interest are the optimal foreign debt, consumption, capital and the growth rate of GDP. They are used as benchmarks of economic performance. By comparing the actual debt to the optimal debt we derive a measure of the sustainability of the debt and vulnerability to default problems. The two sources of uncertainty – the productivity of capital and the real interest rate on the foreign debt – are modeled as stochastic processes. Specific applications of the DP/SOC techniques are given for country defaults in Asia and Latin America, and the US current account deficits.     

产业结构调整中金融发展的作用与定位

产业结构的调整和优化是区域经济发展的重要内容,金融的发展能促进结构优化。同样地,金融抑制会阻碍结构的变迁和变化,两者具有显著的相关关系。本文通过投入产出表,生产函数和比较分析说明金融抑制是产业结构调整的重要障碍,因而在政策选择上,区域经济的发展应结合金融发展动态地促进结构的优化,实现两者的良性循环。     

生产率对中国经济增长的贡献:新的估计

在过去的二十年中,中国经济令人瞩目的增长已经吸引了许多的注意,并由此引发了这一领域内大量文献的出现。这些文献关注的一个问题是中国经济增长中生产率的作用。本文希望通过重新考察关于中国经济增长中生产率作用的争论,对生产率增长提供了一个最新的估计,并由此有助于理解近期的中国经济增长。本文的目的是提出并应用一种增长核算技术,来评估中国经济增长绩效,尤其是技术进步在中国经济增长中的作用。而关于后者的发现可能会对中国未来经济增长的持续性有着重要的政策涵义。     

DEPRECIATION, OBSOLESCENCE AND THE ROLE OF CAPITAL IN GROWTH ACCOUNTING

Maurice Scott has argued that the neoclassical production function and growth accounting are fundamentally flawed as tools for understanding the growth process. If the role of capital were correctly evaluated, then (he argues) the famous 'residual' of growth accounting would disappear. Contrary to these claims, this paper seeks to show that growth accounting gives correct answers to interesting questions, even when all technical progress is embodied in new capital goods and even when depreciation is entirely due to obsolescence.     

IMMIGRANT WAGE GROWTH IN THE UNITED STATES: THE ROLE OF OCCUPATIONAL UPGRADING

Immigrants to the United States routinely take jobs below their skill qualifications because of barriers to entering occupations. We use a structural model of immigrant job choice to quantify the benefits of potential policies to promote entry into suitable occupations. We estimate the model using longitudinal labor market data on immigrants to the United States. Our counterfactual results show that eliminating barriers to occupational entry would lead to only a small earnings increase for the average immigrant in our sample, but a substantial earnings increase for the most highly skilled immigrants.     

ON THE ROLE OF THE PRIMARY SYSTEM IN CANDIDATE SELECTION

How does the type of the primary system affect political outcomes? We address this issue by constructing a simple model that accounts for intra‐party as well as inter‐party political competition. Our model suggests that allowing non‐partisan voters to participate in the primaries (i.e. a semi‐open primary system) indeed improves the chances of a moderate candidate getting elected. However, this need not necessarily happen in the case of a completely open primary system. Under such a system there arise multiple equilibria, some of which may lead to a greater degree of extremism than the closed primary system. Thus, our model contributes to the current debate on the choice of primary systems from an analytical perspective and helps explain some of the empirical findings.     

THE IMPACT OF GOVERNMENT INVESTMENT ORGANIZATIONS IN MALAYSIA ON THE PERFORMANCE OF THEIR PORTFOLIO COMPANIES

Research into the impact of government ownership on the financial performance of listed companies typically assumes the government to be a monolithic entity and fails to consider that government ownership rights are administered by different types of government organizations. Exploring the financial performance of government controlled listed companies we find that in Malaysia the impact of government ownership varies depending on the type of organization which manages the government's ownership stakes. Taking into account golden Share provisions as well as the presence of senior civil servants and of politicians on boards of Directors, we find that firms controlled by investment organizations under federal government control tend to outperform firms controlled by regional governments’ investment organizations.     

中国资本账户开放进程中跨境证券投资对国内金融市场的影响*

随着中国资本项目开放进程的推进,跨境证券投资对国内金融市场的冲击日益增强。在此背景下,本文首先通过构建考虑了资本市场收益率以及有管理浮动汇率制度的IS LM BP模型对跨境证券投资与中国国内金融市场的相互影响机理进行了理论探究,并基于中国2005年7月—2016年8月的月度数据,运用马尔科夫区制转移向量自回归模型对中国资本账户开放进程中跨境证券投资与人民币汇率、股票市场收益率、短期利率的联动关系进行了实证分析。研究结果表明：第一,四者的关联性存在明显的区制特征,区制1主要包括次贷危机时期（2007—2008年）、欧债危机时期（2010—2012年）以及后金融危机时期（2015—2016年）,经济呈现“股票市场收益率较低、跨境证券投资较少、短期利率较高、金融市场波动性大”的状态;区制2主要包括次贷危机前夕（2005—2006年）、次贷危机后的量化宽松时期（2009—2010年）以及欧债危机后的调整期（2013—2014年）,经济呈现“股票市场收益率较高、跨境证券投资较多、短期利率较低、金融市场波动性小”的状态。第二,当处于资本市场化进程较快、金融市场波动性较大的区制阶段（区制1）时,跨境证券投资与国内金融市场的联动关系更加明显。本文研究结论对于我国进一步开放资本市场具有借鉴价值和政策启示。     

ON THE ROLE OF CAPITAL GAINS IN SWEDISH INCOME INEQUALITY

Realized capital gains are typically disregarded in the study of income inequality. We show that in the case of Sweden this severely underestimates the actual increase in inequality and, in particular, top income shares during recent decades. Using micro panel data to average incomes over longer periods and re‐rank individuals according to income excluding capital gains, we show that capital gains indeed are a reoccurring addition to rather than a transitory component in top incomes. Doing the same for lower income groups, however, makes virtually no difference. We also try to find the roots of the recent surge in capital gains‐driven inequality in Sweden since the 1980s. While there are no evident changes in terms of who earns these gains (high wage earners vs. top capital income earners), the primary driver instead seems to be the drastic asset price increases on the post‐1980 deregulated financial markets.     

银行业结构对中小企业融资的影响*

本文结合世界银行关于中国中小企业的调查数据和中国银监会发布的银行业分布数据,分析了银行业结构与中小企业融资的关系。本文发现：银行业结构与中小企业受到信贷配给的概率呈现“U型”关系,即存在最优水平的银行业集中度使中小企业受到信贷约束的概率最低。根据本文研究,我国银行业集中度总体上高于最优水平,但不同地区又有所差异。本文还发现,考察银行业集中度不能只关注国有大型商业银行比重的下降,大型股份制商业银行比重的替代性上升也没有有效解决中小企业融资难的问题。因此,鼓励发展中小金融机构,才是支持中小企业融资的有效途径。     

IN SEARCH OF AN OPTIMAL DEBT RATIO FOR ECONOMIC GROWTH

This paper extends the work of Barro (1979), Eisner (1992), foines (1991), Sawhney and DiPietro (1994), and others and examines whether an optimal debt ratio exists that will maximize economic growth. The growth rate of real GDP is specified as a function of the debt ratio, the debt ratio squared, the growth rates of labor employment, capital services, money stock, and a trend variable. The sample ranges from 1960 to 1991. Hypothesis tests show that economic growth and its determinants, including the debt ratio are cointegrated and have a long-run stable relationship. Results also indicate that the optimal debt ratio is 38.4 percent for debt held by the public and 48.9 percent for total debt. Thus, the current (1993) debt ratios of 50.9 percent for the debt held by the public and 68.2 percent for total debt are far greater than the desirable levels.     

THE IMPACT OF TERRORISM AND CONFLICTS ON GROWTH IN ASIA

This paper quantifies the impact of terrorism and conflicts on income per capita growth in Asia for 1970–2004. Our panel estimations show that transnational terrorist attacks had a significant growth-limiting effect. An additional terrorist incident per million persons reduces gross domestic product per capita growth by about 1.5%. In populous countries, many additional attacks are needed to achieve such a large impact. Transnational terrorism reduces growth by crowding-in government expenditures. Unlike developing countries, developed countries are able to absorb terrorism without displaying adverse economic consequences. An internal conflict has the greatest growth concern, more than twice that of transnational terrorism. Conflict variables are associated with smaller investment shares and increased government spending, with the crowding-in of government spending being the dominant influence.
