Going multinational under exchange rate uncertainty

We analyze a model where an exporting firm competes a la Cournot in a foreign market. The firm faces exchange rate uncertainty and has the option to invest abroad. The paper contributes four results. First, real option pricing techniques are used to derive the optimal timing rule of the investment and the price of the firm and foreign competitors. Second, the sunk cost of entry into the foreign market introduces hysteresis in direct investment flows. We find that the degree of hysteresis grows with the number of firms in the industry. Third, we determine the conditions under which dumping may appear and the role of FDI in precluding this type of dumping. Fourth, tariffs have the well known FDI-inducing effect, more so in less competitive markets, and are more effective at deterring delocation. Furthermore, a tariff might have the effect of triggering dumping.     

金融结构如何影响了外资进入方式选择？

随着全球价值链进入深度重构的关键时期,金融结构对于一国外资进入方式选择的重要性日益凸显,本文采用65个国家2003—2017年跨国面板数据,从理论和实证两个层面系统探讨了金融结构与一国外资进入方式选择之间的关系。研究表明:(1)无论是发达国家还是发展中国家东道国,市场主导型金融结构均有助于外资以跨国并购方式进入东道国,但发达国家正向促进作用显著大于发展中国家,克服了内生性和经济波动的影响后,结论依旧稳健。(2)进一步机制检验结果发现,技术创新引致和国家风险管控是金融结构影响外资进入方式选择的重要渠道。其中,金融结构的国家风险渠道机制,主要通过降低经济金融风险来实现。(3)此外,引入国家营商环境指数发现,营商环境的改善不仅对外资以跨国并购方式进入具有直接促进作用,而且能间接调节金融市场对外资进入结构优化的提升作用。本文研究为我国深化金融供给侧结构性改革,改善营商环境,进而实现引资结构优化提供了政策启示。     

Investment in internet banking as a real option: theory and tests

This paper examines the optimal exercise of strategic real options to invest in Internet banking (IB) technology within a two-stage game, parameterized by the distribution of bank size and uncertainty over the profitability of investment, and empirically tests the results. The value of the strategic investment option to a strategically significant entrant into IB depends on both expected future profits as well as the variance of those profits. Expected profits to an entrant depend, in equilibrium, on its size, as measured by existing market share (concentration) or total assets, relative to its rivals. Conditional on the degree of uncertainty, larger banks should, as a consequence, exercise their options earlier than smaller banks, for purely strategic advantages, and act as market leaders in the provision of IB services. Like ordinary options, however, the value of the strategic investment option to both large and small banks increases in uncertainty, implying that early exercise will be more likely the more information is available about potential demand. We test these hypotheses on investment in IB services with data from a sample of 1618 commercial banks in the tenth Federal Reserve District during 1999. Consistent with our hypotheses, relative bank size, as measured by measures of concentration, and demographic information predictive of future demand both positively influence the probability of entry into IB in our sample.     

外资进入与国内价值链地位提升

近年来,国际经济形势日趋复杂严峻,全球价值链纵向分工趋于缩短或转移至新地点,构建以国内大循环为主体、国内国际双循环相互促进的新发展格局是我国当前经济转型和未来可持续发展的关键。本文利用中国30个省份区域间投入产出表,结合探索性空间数据分析方法和静态、动态多种空间权重矩阵,系统考察了外资进入对我国区域国内价值链地位提升的影响。研究发现,外资进入对国内价值链地位提升具有显著的促进作用;FDI进入地区不仅可以获得直接的技术溢出,而且对相邻地区产生“非自愿”的溢出效应,但省份内FDI溢出效应作用更为明显。在改变计量模型、变量测算形式后,上述结论仍然成立,且不同分组样本(不同技术水平、外资进入程度以及是否沿海地区)对应的检验结果存在异质性。市场化程度强化了外资进入对国内价值链地位提升的促进作用。进一步地,外资进入通过提高国内价值链地位对我国产业结构升级产生正向影响,且直接效应比间接效应更为显著。     

Foreign direct investment and forward hedging

This paper examines the behavior of a risk-averse multinational firm (MNF) making investment in a foreign country under exchange rate uncertainty. To hedge the exchange rate risk, the MNF has access to an unbiased currency forward market. Foreign direct investment (FDI) is irreversible and sequential in that the MNF can acquire additional capital after the exchange rate uncertainty is completely resolved. The MNF as such possesses a real (call) option that is rationally exercised whenever the foreign currency has been substantially appreciated relative to the domestic currency. We show that the MNF's optimal initial level of sequential FDI is always lower than that of lumpy FDI, while the expected optimal aggregate level of sequential FDI can be higher or lower than that of lumpy FDI. We further show that the presence of the currency forward market improves the MNF's incentives to make FDI, both ex-ante and ex-post.     

The 1/N investment strategy is optimal under high model ambiguity

The 1/N investment strategy, i.e. the strategy to split one’s wealth uniformly between the available investment possibilities, recently received plenty of attention in the literature. In this paper, we demonstrate that the uniform investment strategy is rational in situations where an agent is faced with a sufficiently high degree of model uncertainty in the form of ambiguous loss distributions. More specifically, we use a classical risk minimization framework to show that, for a broad class of risk measures, as the uncertainty concerning the probabilistic model increases, the optimal decisions tend to the uniform investment strategy.To illustrate the theoretical results of the paper, we investigate the Markowitz portfolio selection model as well as Conditional Value-at-Risk minimization with ambiguous loss distributions. Subsequently, we set up a numerical study using real market data to demonstrate the convergence of optimal portfolio decisions to the uniform investment strategy.     

Valuation of a Developmental Drug as a Real Option

Valuing a capital investment as a real option (or series of options) has advantages over standard DCF valuation when the investment creates the future flexibility to delay, abandon, or expand an element of the project based on the resolution of a major source of uncertainty. The uncertainty is generally dealt with using a “volatility” term that aims to reflect the variability in the future value of the underlying asset. But there are certain situations in which the uncertainty has a second dimension. For example, drugs in development can be abandoned either because of bad technical outcomes (the drug doesn't work) or unfavorable resolutions of market risk (though the drug works, its market potential turns out to be too limited). In an article published earlier in this journal, the authors illustrated the valuation of an early‐stage pharma R&D investment using a real options approach in which the market and technical risks were folded together into the volatility parameter. In this article, the authors explain why they have concluded that this is an incorrect approach and then show how to handle market and technical risk as two separate dimensions of risk in valuing an R&D program. The potential use of this technique extends beyond pharma and biotech R&D to any situation in which the outcome of an important uncertainty is independent of the resolution of market risk associated with the underlying asset.     

Optimal investment of an insurer with regime-switching and risk constraint

We investigate an optimal investment problem of an insurance company in the presence of risk constraint and regime-switching using a game theoretic approach. A dynamic risk constraint is considered where we constrain the uncertainty aversion to the ‘true’ model for financial risk at a given level. We describe the surplus of an insurance company using a general jump process, namely, a Markov-modulated random measure. The insurance company invests the surplus in a risky financial asset whose dynamics are modeled by a regime-switching geometric Brownian motion. To incorporate model uncertainty, we consider a robust approach, where a family of probability measures is cosidered and the insurance company maximizes the expected utility of terminal wealth in the ‘worst-case’ probability scenario. The optimal investment problem is then formulated as a constrained two-player, zero-sum, stochastic differential game between the insurance company and the market. Different from the other works in the literature, our technique is to transform the problem into a deterministic differential game first, in order to obtain the optimal strategy of the game problem explicitly.

中国股票市场近年开始重新重视价值投资,但真正能运用价值投资策略进行投资的并不多见。本文研究在我国的证券市场中,价值投资是否适用和有效,通过实证分析的方法,检验价值投资策略在中国证券市场的适应性。本文的结论有助于逐渐改变目前中国证券市场上中小投资者跟风炒作、希望在短期内获得高额回报的投机理念和过度炒作的现象,对于提倡理性投资,抑制过度投机是非常有益的。     

Investment, Uncertainty, and Liquidity

We analyze the dynamic investment decision of a firm subject to an endogenous financing constraint. The threat of future funding shortfalls lowers the value of the firm's timing options and encourages acceleration of investment beyond the first‐best optimal level. As well as highlighting another way by which capital market frictions can distort investment behavior, this result implies that (1) the sensitivity of investment to cash flow can be greatest for high‐liquidity firms and (2) greater uncertainty has an ambiguous effect on investment.     

模糊厌恶下股指期货风险对冲策略设计及实证分析

投资者对股指期货与现货有着不同的模糊厌恶,本文首先将此假设条件引入带交易成本的Garleanu and Pederson (2013)投资模型中,并以指数基金对冲策略为例,构建了一个股指期货动态对冲的理论模型。与非对冲策略相比,基于上述模型设计的对冲策略投资绩效更好,动态最优成交额占目标交易额的比例更小,目标成交额对收益率预测因子的敏感性更大。借助上述模型,本文选取2010年4月至2021年6月的中国ETF指数基金和股指期货数据,并以2015年9月股指期货管理措施实施为界进行区间划分,实证研究发现:(1)中国A股市场的ETF投资组合进行股指期货对冲显著提升了投资绩效,但股指期货管理会削弱该作用;(2)投资绩效改善主要来源于交易成本的下降与目标成交额因子敏感性的提升,该机制受到股指期货管理的约束;(3)与Garleanu and Pederson (2013)、Zhang et al. (2017)相比,本文对冲策略保留“抗跌”特点的同时增加了“易涨”特性。本文研究结果表明,在当前大力发展机构投资者的背景下应不断丰富股指期货、股指期权产品谱系,降低股指期货交易成本并完善持仓约束。     

Incumbents and protectionism: The political economy of foreign entry liberalization

This paper investigates the influence of incumbent firms on the decision to allow foreign direct investment into an industry. Using data from India's economic reforms, the results show that firms in concentrated industries are more successful at preventing foreign entry, state-owned firms are more successful at stopping foreign entry than privately-owned firms, and profitable state-owned firms are more successful at stopping foreign entry than unprofitable state-owned firms. The pattern of foreign entry liberalization supports the private interest view of policy implementation and suggests that it may be necessary to reduce the influence of state-owned firms to optimally enact reforms.     

Buy-and-hold mean-variance portfolios with a random exit strategy

We show how buy-and-hold investors can move from horizon uncertainty to profit opportunity. The analysis is conducted under a risk-averse framework rather than the standard Markowitz formulation in the case of i.i.d. asset processes. We make this practical achievement by considering a threshold stopping rule as the strategy to determine when to exit the market. The resulting investment horizon is random and can be correlated with the market. Under this setting, we first provide an analytical approximation to optimal weights, and then identify a class of reference variables associated with the stopping rule that leads to ex-ante improvements in portfolio allocation, vis-a-vis the fixed exit time alternative. The latter conclusion is based on a generalization of the Sharpe ratio, adjusted for horizon uncertainty. The obtained investment suggestion is simple and can be implemented empirically.     

Homemade international diversification under economic policy uncertainty

We examine how US mutual funds that invest domestically make portfolio adjustments by incorporating US-listed foreign stocks (cross-listed stocks) when faced with US market economic policy uncertainty. We document a positive association between US economic policy uncertainty and US mutual funds’ weight of cross-listed stocks, and find that the effect is concentrated in funds that mainly invest in the US domestic market. The findings are not sensitive to the instrumental variable approach, model specification, sampling, variable definition, and controlling for macro characteristics. Funds with higher weight of cross-listed foreign stocks when US economic policy uncertainty increases outperform other funds, indicating the rationality of such an investment strategy. A long-short portfolio generates 3.4% annualized abnormal return in the immediate following quarter. Our study shields light not only on the international diversification benefit of US-listed foreign stocks but also on the importance of capital market openness for domestic investors.     

Determinants of US investment in real estate abroad

The purpose of this paper is to analyse and discuss those factors which are contributing to the expansion of US FDI in real estate. The empirical results of this model of FDI in real estate show that as US foreign financial liabilities increase, there is an accompanying increase in its FDI in real estate. This result is consistent with the study by Russekh, F., Ruffin, R., 1986. The role of foreign direct investment in US capital flows. Am. Econ. Rev. 76, 1127–1130, who showed that US FDI abroad is a substitute for US financial assets. Furthermore, the empirical results indicate that as returns from the US stock market decline, there are more incentives for US investors to invest in foreign real estate. The empirical results also show that US financial wealth, US FDI in manufacturing and banking and US bilateral trade contribute positively to the expansion of US FDI in real estate.     

Dynamic portfolio strategy by loss-averse fund managers facing performance-induced fund flows

In a continuous-time framework, we establish an optimal dynamic portfolio strategy for a loss-averse fund manager facing performance-induced fund flows. Using the martingale approach, we derive closed-form solutions to both the optimal terminal value and optimal dynamic strategy of the fund under management. The model shows that the loss-averse manager strives to earn high returns in good market conditions at the risk of losing all investments at the terminal date in bad market conditions. The prospect of higher fund inflows induced by superior performance motivates fund managers to take more aggressive investment strategies, increasing the fund's risk exposure, whereas the prospect of fund outflows due to underperformance has no impact on the fund manager's investment decision. While the prospect of higher fund inflows increases dynamic optimal wealth as well as optimal terminal wealth in good market conditions, in bad market conditions, it reduces dynamic optimal wealth and results in a higher chance of a complete loss at the terminal date. Finally, a manager with a higher degree of loss aversion tends to take a conservative investment strategy with a lower risk exposure especially in bad market conditions, leading to a lower dynamic and terminal wealth in good market conditions and also a lower chance of a complete loss in bad market conditions.     

MORGAN STANLEY ROUNDTABLE ON Capital Structure and Payout Policy

A group of distinguished finance academics and practitioners discuss a number of topical issues in corporate financial management: Is there such a thing as an optimal, or value‐maximizing, capital structure for a given company? What proportion of a firm's current earnings should be distributed to the firm's shareholders? And under what circumstances should such distributions take the form of stock repurchases rather than dividends? The consensus that emerges is that a company's financing and payout policies should be designed to support its business strategy. For growth companies, the emphasis is on preserving financial flexibility to carry out the business plan, which means heavy reliance on equity financing and limited payouts. But for companies in mature industries with few major investment opportunities, more aggressive use of debt and higher payouts can add value both by reducing taxes and controlling the corporate free cash flow problem. In such cases, both leveraged financing and cash distributions through dividends and stock buybacks signal management's commitment to its shareholders that the firm's excess cash will not be wasted on projects that produce low‐return growth that comes at the expense of profitability. As for the choice between dividends and stock repurchases, dividends provide a stronger commitment to pay out excess cash than open market repurchase programs. Stock buybacks, at least of the open market variety, preserve more flexibility for companies that want to be able to capitalize on unpredictable investment opportunities. But, as with the debt‐equity decision, there is an optimal level of financial flexibility: too little can mean lost investment opportunities, but too much can lead to overinvestment.     

Total Factor Productivity,Foreign Direct Investment,and Entry Barriers in the Chinese Automotive Industry

We explore three questions on foreign direct investment (FDI): (1) What are the differences in entry barriers for foreign, public, and private investors? (2) What are the effects of past productivity levels on future foreign direct investment (FDI) decisions? (3) What is the effect of equity structure on future total factor productivity (TFP) levels? The empirical results based on a monopolistic competition model and using a firm-level data set from the Chinese automobile industry suggest that foreign investors face higher entry barriers and react stronger to past TFP levels. FDI is also found to improve future TFP more than other forms of investment. Finally, World Trade Organization (WTO) accession is found to reduce entry barriers for foreign and domestic private investors while increasing entry barriers for public investors.     

Stock Market Valuation,Foreign Investment,and Cross-Country Arbitrage

This study investigates the role of stock market valuation and cross-country arbitrage in shaping foreign direct and indirect investments, contingent upon a country's stage of development. This paper is built upon the mispricing-driven foreign investment hypotheses developed by Baker, Foley, and Wurgler (2009). Interesting findings emerge when developed and emerging markets are considered separately. Empirical evidence indicates that the use of relatively cheap financial capital for foreign investment is prominent among developed countries, but not so in emerging markets. This is largely due to the extremely low level of foreign investment outflows in emerging markets and the inability of unsophisticated emerging market managers to successfully time the market. Further investigation shows that host-country stock market valuation is an important determinant of the mode of foreign investment; investors tend to choose indirect or portfolio investment, as opposed to direct investment, when the stock market is perceived to be undervalued. This is especially the case in emerging markets, where there is more room for misvaluation and potential arbitrage. These findings suggest that the unique institutional features of the markets involved play an important role in shaping foreign investment and cross-country arbitrage.
