Financial integration and international risk sharing

Conventional wisdom suggests that financial liberalization can help countries insure against idiosyncratic risk. There is little evidence, however, that countries have increased risk sharing despite widespread financial liberalization. We show that the key to understanding this puzzling observation is that conventional wisdom assumes frictionless international financial markets, while actual markets are far from frictionless: financial contracts are incomplete and contract enforceability is limited. When countries remove official capital controls, default risk is still present as an implicit barrier to capital flows. If default risk were eliminated, capital flows would be six times greater, and international risk sharing would increase substantially.     

International capital flows,returns and world financial integration

International capital flows have increased dramatically since the 1980s, with much of the increase being due to trade in equity and bond markets. Such developments are often attributed to the increased integration of world financial markets. We present a model that allows us to examine how greater integration in world financial markets affects the behavior of international capital flows and financial returns. Our model predicts that international capital flows are large (in absolute value) and very volatile during the early stages of financial integration when international asset trading is concentrated in bonds. As integration progresses and households gain access to world equity markets, the size and volatility of international bond flows decline. This is the natural outcome of greater risk sharing facilitated by increased integration. This pattern is consistent with declining volatility observed during 1975–2007 period in the G-7 countries. We also find that the equilibrium flows in bonds and stocks predicted by the model are larger than their empirical counterparts, and are largely driven by variations in equity risk premia. The model also predicts that volatility of equity and bond returns decline with integration, again consistent with the data for G-7 economies.     

The role of multinational production in a risky environment

This paper explores the aggregate consequences of Foreign Direct Investment (FDI) on the opportunities for risk diversification available to consumers. The crucial difference between FDI and other international financial flows is that the former involves technology flows across countries. We present a model where firm-embedded productivity can be transferred costly across countries through the activity of multinational firms. We find that risk patterns affect multinationals' location decisions and, in turn, these decisions change the scope for international risk diversification even in a world with complete financial markets.     

Comparative Advantage and the Gains from Financial Trade: A Reappraisal

Emerging market crises have suggested that a national benefit‐cost assessment of external financial liberalisation could well prove unfavourable. This paper re‐examines the principle of comparative advantage in its application to financial trade to seek guidance on measures that might permit a fuller realisation of the potential benefits involved. Drawing a parallel with Balasubramanyam's work on the gains from FDI and international migration we distinguish between those arising in financial trade from the net transfer of capital, and those deriving from the contemporaneous exchange of financial claims or services of equivalent value. In the first interpretation a country's comparative advantage is manifested by its role in ‘intertemporal’ trade (as a borrower or lender). Our alternative emphasis is on the contractual risk‐return characteristics of the financial claims exchanged. This perspective is applied firstly to portfolio diversification gains arising from further international stock market integration. Secondly, price risk management for developing countries in international primary commodity trade is discussed. Both applications imply the need for significant institutional development but could realise approximately contemporaneous gains reminiscent both of those involved in merchandise trade and in the skills and product (or service) flows that Balasubramanyam has emphasised in relation to FDI and international migration.     

Resource-based FDI and expropriation in developing economies

Globally, foreign direct investment (FDI) assets are expropriated more in resource extraction industries compared to other sectors. Despite the higher apparent risk of expropriation in resources, countries more likely to expropriate also have a larger share of FDI in the resource sector. An incomplete markets model of FDI is developed to account for this puzzle. The type of government regime is stochastic, with low penalty regimes facing a relatively low, exogenous cost of expropriating FDI, and country risk is measured by the variation in these costs across different regimes. The key innovation of the model is that the government, before the regime type is known, is able to charge different prices to domestic and foreign investors for mineral rights. Granting cheap access increases FDI and reduces the country's share of resource rents, increasing the temptation to expropriate in a relatively low penalty regime. In very high-risk countries, subsidizing resource FDI increases the total value of output by raising investment, and the net gains from expropriating in a low penalty regime outweigh the rents foregone under a high penalty one. However, a stochastic resource output price results in relatively low-risk countries restricting FDI inflows to the resource sector instead — “windfall profits” in this sector raise incentives to expropriate when prices are high, yet minimization of the ex ante risk of expropriation is preferred owing to the relatively high penalty for expropriating. These results imply a higher average share of resource-based FDI in countries most likely to expropriate, while resources account for a high share of expropriated assets compared to the sector's global share of FDI. We show that the model is able to reconcile observed patterns of foreign investment and expropriation for a sample of 38 developing and emerging economies.     

The Role of Geography in Financial and Economic Integration: A Comparative Analysis of Foreign Direct Investment,Trade and Portfolio Investment Flows

The objective of this paper is to examine the role of geography in explaining the patterns of financial and economic integration among both developed and developing countries. Using a gravity model, we compare North‐North, North‐South and South‐North FDI, trade and portfolio investment flows to examine how geographical factors influence these bilateral flows. The results indicate that the impact of geography variables on FDI and portfolio are similar to their effect on trade. Geography variables have a statistically significant effect both on FDI and portfolio investment, but FDI is more sensitive to distance. We interpret the negative effect of distance as the existence of information costs in financial flows. Also bilateral FDI, trade and portfolio investment flows react to macroeconomic fundamentals in the same way, however, with different degrees of sensitivity. There are significant differences between North‐North and North‐South flows. Our results find support for the argument that most FDI among industrial countries are horizontal, whereas most FDI investment in developing countries is vertical. The fact that the significance of geographical variables on financial flows still remained even after controlling for the macroeconomic fundamentals, is in contrast with the standard capital market model. The results can, however, be reconciled if geographical factors can proxy for information costs, which may in turn explain why country portfolios are still home‐biased. The significant effect of distance on financial flows may also explain how idiosyn cratic shocks are spread (i.e. contagion) to other countries in the same region. Ultimately, the geographical location of a country may determine its economic and financial integration into the world economy.     

FDI,market signal and financing constraints of firms in China

On the basis of an augmented Euler equation, we use firm survey data provided by the World Bank to investigate the impact of FDI (foreign direct investment) on the financing constraints of firms in China. First we calculate the forward and backward linkages of FDI. Then through empirical estimation, we find that only private firms have financing constraints and that the incoming FDI alleviates this situation. Private firms with more foreign capital shares or having stronger vertical linkage with FDI can get financial resources easily. Furthermore, industries hosting a large amount of FDI are favorite clients of the financial institutions because they are usually much more competitive in the world. As a result, the private firms in these industries also have easier access to financial resources. In the financial market, FDI is a helping hand that reduces the information asymmetry between firms and financial institutions. Financial resources go where FDI goes, which to some extent improves the allocation efficiency.     

The Political Economy of Basle II: The Costs for Poor Countries

The financial crises of the 1990s triggered many changes to the design of the international financial system. We use the formulation of the new Basle capital accord for banks (B‐II) to illustrate that, while much affected, developing countries have had very little influence on this so‐called new international financial architecture. We argue that B‐II has been formulated largely to serve the interests of powerful market players, with developing countries being left out. At the same time, we demonstrate that B‐II is likely to raise the costs and reduce the supply of external financing for developing countries in particular. Furthermore, and importantly, B‐II may well increase the pro‐cyclicality of external financing, an unfortunate outcome given that developing countries already face much volatility in terms of capital flows. Overall, while B‐II may indeed compensate for a range of weaknesses of Basle I, the exclusionary policy process and costs which B‐II imposes on developing countries require a re‐think of the way in which crucial elements of financial governance, such as the Basle capital accords, are developed and implemented.     

Trade Wars: The Exaggerated Impact of Trade in Economic Debate

The rules governing trade and capital flows have been at the centre of controversy as globalisation has proceeded. One reason is the belief that trade and capital flows have massive effects on the labour market – either positive, per the claims of international financial institutions and free trade enthusiasts, or negative, per the ubiquitous protestors at WTO, IMF and World Bank meetings demanding global labour standards. Comparing the claims made in this debate with the outcomes of trade agreements, this paper finds that the debate has exaggerated the effects of trade on economies and the labour market. Changes in trade policy have had modest impacts on the labour market. Other aspects of globalisation – immigration, capital flows and technology transfer – have greater impacts, with volatile capital flows creating great risk for the well-being of workers. As for labour standards, global standards do not threaten the comparative advantage of developing countries nor do poor labour standards create a ‘race to the bottom’.     

Home bias and high turnover: Dynamic portfolio choice with incomplete markets

Why do investors trade a lot in foreign assets and hold so little of them in their portfolios? This paper shows that both observations can arise naturally in the presence of nondiversifiable nontraded consumption risk when each country specializes in production, preferences exhibit consumption home bias, and asset markets are incomplete. Using a general equilibrium two-country, two-sector (tradable and nontradable) model of the world economy with production I show that low diversification occurs because variations in relative prices (i) increase the riskiness of foreign assets and (ii) facilitate risk-sharing across countries. Large and volatile capital flows are necessary to take advantage of international risk premia differentials that occur in response to productivity changes in the nontradable sector. I characterize the optimal portfolio holdings, the evolution of the investment opportunity set, the risk premium, and the dynamics of capital flows using a new methodology for solving dynamic general equilibrium models with incomplete markets and portfolio choice.     

VMI模式下信息共享对违约风险的防范和控制

供应商管理库存（Vender Managed Inventory,VMI）是21世纪前沿的供应链管理模式,VMI对供应链的新形式供应的形成和发展都产生了影响。但由于我国信息化起步晚,使得很多企业在实施VMI模式时仍存在不同程度的风险。为了实现对VMI违约风险防范和控制的有效性,供应链上的各个企业越来越注重供应链成员之间的协调关系,而这就需要以供应链上各个节点的成员企业进行高质量的信息传递和及时完整的信息共享为基础来建立和完善整个VMI系统。研究供应商实施VMI的过程中所面临的违约风险,重点分析VMI模式下信息共享对违约风险防范控制作用,可有效地实现信息共享以降低VMI模式下的违约风险。     

SMEs,foreign direct investment and financial constraints: The case of Belgium

This paper explores the problems experienced by small and medium-sized enterprises (SMEs) with international ambitions in gaining access to debt and equity finance for foreign direct investment (FDI) projects. We develop several arguments for why such small businesses are expected to face severe financing constraints for foreign investments and provide an explorative empirical study with both the demand and supply side of FDI finance. We have interviewed thirty-two Belgian SMEs that carry out FDI, five banks and five venture capitalists. Based on the SME discussions, we have composed a questionnaire that was sent to the interviewed SMEs. The information problems and lack of collateral that often characterize international investment, the home bias of financiers and the capital gearing method used by banks to evaluate small firms’ foreign projects give rise to financial constraints for SMEs’ FDI projects. The reported finance gap hinders small firms’ (international) development and leads to suboptimal home and FDI host country development.     

Sharing contracts' marginalisation,adverse selection and markup calculation

This paper proposes a new approach to explain the dominance—in the Islamic banking market—of markup contracts at the expense of sharing ones. We show that the dual pricing practised in this market produces an additional—or artificial—dimension of adverse selection, which is causing the sharing contracts' marginalization. We suggest specialized use of two Islamic contractual categories as a device for eliminating artificial adverse selection. We suggest also an endogenous calculation of the markup, that is independent of the interest rate, based on the financing cost unification. This approach allows the deduction of default and liquidity risk premiums.     

International good market segmentation and financial innovation

While international capital flows are now well liberalized, markets for goods remain segmented. To investigate how financial innovation may relieve the effects of this segmentation on risk sharing, we examine a series of two-country economies with internationally segmented good markets, distinguished by the available financial securities. Sufficient conditions for efficiency include complete international financial markets together with liberalized international financial flows. Under these conditions, heterogeneous agents from the same country may use securities as a substitute for the international shipment of goods. This allows them to partially circumvent the segmentation, allowing for efficient risk sharing.     

Towards a theory of trade finance

Shipping goods internationally is risky and takes time. To allocate risk and to finance the time gap between production and sale, a range of payment contracts is utilized. I study the optimal choice between these payment contracts and their implications for trade. The equilibrium contract is determined by financial market characteristics and contracting environments in both the source and the destination country. Trade increases in enforcement probabilities and decreases in financing costs proportional to the time needed for trade. Empirical results from gravity regressions are in line with the model, highly significant and economically relevant. They suggest that importer finance is as important for trade as exporter finance.     

税收饶让抵免对涉外投资影响效应的实证研究

为研究双边税收协定中饶让抵免条款对我国涉外投资的影响效应,运用2003~2010年37个国家的宏观面板数据,通过一个简单的实证分析模型分别检验了外国予以我国的税收饶让对外国对华直接投资（FDI）的影响以及我国予以外国的税收饶让对我国对外直接投资（ODI）的影响。结果表明,税收饶让明显刺激了外国直接投资流量,但并未发现税收饶让对我国对外直接投资具有显著的促进作用。据此,建议在进行双边税收谈判与协定签订时,既要争取外国对我国的饶让抵免优惠,也要积极给予对外投资战略合作国家以税收饶让,从而充分利用国际税收协定,促进国内战略资本的优化布局,实现＂引进来＂与＂走出去＂的双向协调。     

Credit constraints, equity market liberalizations and international trade

This paper provides evidence that credit constraints are an important determinant of international trade flows. I exploit shocks to the availability of external finance and examine the impact of equity market liberalizations on the export behavior of 91 countries in the 1980-1997 period. I show that liberalizations increase exports disproportionately more in financially vulnerable sectors that require more outside finance or employ fewer collateralizable assets. This result is not driven by cross-country differences in factor endowments and is independent of simultaneous trade policy reforms. Moreover, it obtains with equal strength in the full panel of countries as well as in both panel and event-study analyses of countries which removed capital controls during the sample period. Finally, the effects of liberalizations are more pronounced in economies with initially less active stock markets, indicating that foreign equity flows may substitute for an underdeveloped domestic financial system. Similarly, opening equity markets has a greater impact in the presence of higher trade costs caused by restrictive trade policies.     

我国企业在南南直接投资中的竞争优势分析

改革开放以来,我国吸引外商直接投资规模逐年增加,处于世界领先地位,但对外直接投资方面则处于世界落后地位。截至2004年,我国对外直接投资存量为449亿美元,仅占全球对外直接投资存量的0.55%。根据我国企业在对外直接投资方面的竞争力水平,很难在短期内大规模进入欧美等发达国家的投资市场,但在对其他发展中国家的直接投资———南南直接投资中,我国企业无论与发展中国家的竞争对手相比还是与发达国家的竞争对手相比,均有一定的竞争优势。我国企业应当正确认识自身的竞争优势,以南南直接投资为突破口,培植国际竞争力,推动“走出去”战略。     

Financial Development and Economic Growth in Africa

We revisit in this paper the debate between financial development and economic growth. In contrast to previous studies examining banking related measures, we focus on the capital account and the depth of African stock markets. We examine 15 African countries from 1995 to 2010 and employ both static and dynamic panel data methods. While the former suggest weak results overall, portfolio flows and Foreign Direct Investment (FDI) have consistently positive effects on economic growth under endogenous stock market capitalization. These findings reinforce the view that African countries should open their equity markets to international investors and encourage FDI.     

公司和农户间自我履约机制的设计:一种风险贴水的方法

"公司+农户"这一组织模式在其运行过程中面临着越来越多的问题与困境,高违约率的现实使得分析公司和农户间契约的内在机制、设计更加有效的契约形式显得尤为迫切。在我国法律尚不能完全强制契约执行的前提下,合理的风险分担机制应该是解决农业契约违约率过高、提高农业契约运作效率的基本方向。基于重复博弈理论,公司和农户签订长期契约并且将风险贴水作为一种自我履约机制,将有助于抑制公司的违约倾向,保证契约的稳定运作。
