Aid Volatility and Real Business Cycles in a Developing Open Economy

This article analyzes the impact of the unpredictability of foreign aid on macroeconomic fluctuations in the recipient country. I build a small open‐economy business cycle model that accounts for foreign aid shocks, with no preference shocks. The model is calibrated to reflect the structural empirical regularities of Cote d'Ivoire, a typical aid‐dependent developing country. The parameters of the exogenous shocks are estimated using Bayesian methods and time series data for Cote d'Ivoire. The model produces business cycle patterns that are consistent with the data and key stylized facts. Specifically, the excess volatility of consumption with respect to output is successfully replicated. The results suggest that the unpredictability of foreign aid contributes to explain the volatility of business cycles in the recipient economy and has negative welfare effects.     

External Shocks and High Volatility in Consumption in Low‐Income Countries

According to the well‐known concept of consumption smoothing, the volatility of consumption is low even when income is volatile; this is confirmed by data from G7 countries. Surprisingly, however, consumption volatility in many low‐income countries is nontrivially higher than income volatility. Here I examine what causes high consumption volatility in low‐income countries. In general, volatile consumption makes consumers worse off. Therefore, understanding the causes of high consumption volatility can contribute to improving welfare in low‐income countries by suggesting measures to assist in the stabilization of consumption. Unlike much previous research, I focus on international factors when explaining high consumption volatility. The results suggest that external shocks, which are far more volatile in low‐income countries than in industrialized countries, strongly swing consumption. By capturing these mechanisms, the model I use successfully accounts for consumption volatility's differences between the sample low‐income country and sample industrialized country.     

Optimal Exit Costs of Foreign Direct Investment

This paper examines the optimal policy on exit costs of foreign direct investment for a host country considering the impact of varying income level and host country’s risk aversion against volatile FDI flows. Based on a dynamic model about the impact of the exit costs on FDI inflows and capital formation, we demonstrate that a host country should determine the exit cost considering two counterbalancing factors, that is, facilitating higher FDI inflows and reducing volatility of FDI inflows. When a host country is less vulnerable to volatility with inelastic risk aversion against FDI volatility, it is optimal for the host country with a negative income shock to take a more aggressive approach to induce FDI inflows by lowering exit costs. However, if the host country is more vulnerable to volatility with elastic risk aversion, the host country is advised to take a conservative approach by increasing exit costs to reduce FDI volatility. These findings, supported by the OECD data on 42 countries’ exits costs, implicate that developing countries are recommended to lower exit costs to induce higher FDI inflows when they are not highly vulnerable to volatility shocks.     

Capital Flows,Financial Intermediation and Macroprudential Policies

This paper develops an open-economy DSGE model with an optimizing banking sector to assess the role of capital flows, macro-financial linkages, and macroprudential policies. The key result is that macroprudential measures can usefully complement monetary policy. Countercyclical macroprudential polices can help reduce macroeconomic volatility and enhance welfare. The results also demonstrate the importance of capital flows and financial stability for business cycle fluctuations as well as the role of supply side financial accelerator effects in the amplification and propagation of shocks.

International capital flows,debt overhang and volatility

This paper shows how international capital flows originate boom‐bust and sunspot episodes in a neoclassical growth model of a small, open economy. A limit is imposed on how much the economy can borrow from foreign creditors and it is made endogenous by assuming that the debt‐to‐GDP ratio is procyclical. The steady state is locally indeterminate when the credit multiplier is larger than some threshold level, whereas saddle‐point stability prevails when the credit multiplier is low enough. As a consequence, high levels of the credit multiplier lead to both booms followed by busts and sunspot‐driven volatility near the steady state, while, in contrast, low levels ensure monotonic convergence. Compared with saddle‐path equilibria, boom‐bust and sunspot equilibria are associated with both lower welfare and debt overhang, that is, a crowding‐out effect of credit: when the economy is highly leveraged, it uses savings to cut down foreign debt, at the expense of both human and physical investment. Numerical examples show that indeterminacy arises for debt‐to‐GDP ratios that fall within the range of available estimates. Finally, the effects of shocks to the world interest rate on output and consumption are amplified and persistent in the debt overhang regime.     

Exchange rate movements and foreign direct investment (FDI): Japanese investment in Asia, 1987–2008

The paper estimates the impact of exchange rate movements on foreign direct investment (FDI). By using the panel data of Japanese FDI flows to nine dynamic Asian economies during 1987–2008, the paper finds that (i) FDI declined with a depreciation of the yen against host country currencies; (ii) it increased with exchange rate volatility; and (iii) it was little affected by the Asian financial crisis, especially when disguised financial flows were removed from the data. A novel result concerns the negative response of FDI to the third moment of monthly exchange rate changes: the volume of FDI was smaller when the distribution was positively skewed (i.e., when the yen was biased towards relatively large depreciation shocks). If skewness proxies for expected mean-reverting changes, this supports the idea that source country investors care about the future stream of revenues and returns denominated in their own currency. These results are robust, with other standard control variables having statistically significant coefficients with expected signs.     

Business Cycle Fluctuations,Large Macroeconomic Shocks,and Development Aid

We examine the cyclical properties of development aid using bilateral data for 22 donors and 113 recipients during 1970–2005. We find that bilateral aid flows are on average procyclical with respect to the business cycle in both donor and recipient countries. While aid outlays contract sharply during severe downturns in donor countries, they rise steeply when aid-receiving countries experience large adverse shocks. Our findings suggest that development aid may play an important cushioning role in developing countries, but only during times of severe macroeconomic stress. Our results are robust to alternate definitions of aid flows, specifications, and estimation techniques.     

AID AND DEVELOPMENT IN AFRICA: THE DEBATE, THE CHALLENGES AND THE WAY FORWARD

The article discusses the emerging literature and debates on aid, within the context of expected increases in aid flows to the continent. The trends in ODA flows indicate a reversal in aid flows to the continent since 2000, with subsequent increases in aid intensity and dependence. Although the more recent literature on aid is doubtful if aid only spurs growth in a in a good policy environment, the aid‐institutional debate indicates a clear aid‐institutional paradox, especially relating to the macroeconomic effects, the fiscal response, the absorptive capacity and the good governance aid debates. The literature further indicates that aid could serve as a barrier to vulnerable societies. From the donors' perspective, it is evident that quantity of aid does not imply quality and that the ultimate responsibility lies with recipient governments to ensure more efficient absorption of aid.     

The Impact of the US Interest Rate Hike on Emerging Market Economies and the Belt and Road Initiative

Since the end of 2015, the US Federal Reserve has raised its benchmark interest rate nine times. This has led to capital outflows and asset depreciation in many emerging market economies. The present paper examines the factors that determine the financial volatility of emerging markets in the face of external shocks. By calculating the capital flows of 30 emerging markets from 1990 to 2018 and conducting panel regression, this paper finds that countries with good infrastructure facilities, a sound banking system and high economic growth have significantly lower cross‐border financial risks. An implication from the empirical analysis is that emerging countries would benefit greatly by actively taking part in the Belt and Road Initiative. The framework of the Belt and Road Initiative allows emerging countries better access to China's massive consumer market to promote trade and long‐term growth. Their quality of infrastructure can be improved through cooperation with China in infrastructure investment. They can also jointly establish a cooperative financial framework to enhance regional financial stability. These strategies will reduce systematic financial risks and counteract the negative impacts of US interest rate hikes.

人口流动是我国经济的热点问题之一，那么人口流动管制对我国宏观经济波动有什么样的影响?文章在标准RBC一般均衡模型中引入了异质性高低技能劳动，考察了人口流动管制对宏观经济波动的影响。研究发现：（1）劳动人口流动管制对总产出和总消费都有负向影响，会增加低技能工资，降低高技能工资；（2）资本质量冲击、政府购买冲击不仅会使消费和工资水平下降，同时也会造成福利下降，其中单位政府购买冲击会使居民福利下降最大，低技能总福利损失大于高技能总福利损失；（3）通过方差分解发现人口流动冲击能解释产出波动的7.83%和投资波动的5.60%，同时还发现随着经济中高技能比重加大，单位人口流动负冲击对社会福利损失越大。文章基于人口流动管制异质性视角研究得出流动人口管制不利于经济增长和社会总福利，为我国流动人口研究提供了新的研究视角。     

Exchange Rate Volatility and Growth in Emerging Europe and East Asia

The paper investigates the impact of exchange rate volatility on growth in Emerging Europe and East Asia. Exchange rate stability has been argued to affect growth negatively as it deprives countries from the ability to react in a flexible way to asymmetric real shocks and increases the probability of speculative capital inflows and overheating. In contrast, exchange rate stability can be argued to affect growth in emerging market economies positively as transactions costs for international trade decline, uncertainty for international capital flows is less and macroeconomic stability is enhanced. Cross country panel estimations provide evidence for a negative impact of the exchange rate volatility on growth in both Emerging Europe and East Asia. Parts of this negative growth effect can be associated with exchange rate volatility caused by macroeconomic instability.     

Foreign aid and fiscal response: Does aid disaggregation matter?

Foreign Aid and Fiscal Response: Does Aid Disaggregation Matter? —The present paper constitutes a new approach in the aid-effectiveness literature in two important respects. Firstly, it develops and then tests a model of foreign aid and fiscal response, which, for the first time in the aid-effectiveness literature, embraces the aiddisaggregation issue; we do this by disaggregating aid flows into three main components, namely programme aid, project aid and technical assistance, and by subsequently estimating our model for two countries, India and Kenya. Secondly, on the modelling front, we improve on earlier work in this area by using an appropriate specification for the recipient-country government’s welfare function, with significant positive implications for the empirical findings obtained. This new approach adopted in the paper and the empirical results obtained may have important implications for a better understanding of the fiscal impact of aid in aid-recipient countries.     

Spillovers in Exchange Rates and the Effects of Global Shocks on Emerging Market Currencies

This paper provides an investigation into the spillover effects of exchange rate returns and volatility for developed and emerging market currencies, using data from 1997 to 2011. The results suggest that spillovers in exchange rate returns have increased steadily over time, in moderate reaction to economic events. In contrast, spillovers in total observed volatility (measured by squared returns) react more strongly to economic events, and this transmission has remained at a relatively high level since the global financial crisis. Furthermore, over the course of time, global shocks would appear to account for a larger proportion of aggregate exchange rate volatility (and the relative importance of domestic shocks has declined). The paper also considers whether the increase in volatility spillover is due to sudden shocks, or whether it is due to changes in the stochastic trend of the underlying volatility process. The results suggests that in most cases, this increase is due to sudden shocks, however, in certain instances country‐specific events may perpetuate changes to the trend of the underlying volatility spillover.     

Foreign aid as a promotional strategy

Developed countries are motivated by several forces when allocating aid to developing countries. The forces could be humanitarian in one country, and commercial self-interests in another. The principal objective of this study was to determine the effectiveness of aid as a promotional strategy for trade, and to investigate whether major donor countries are optimally allocating their aid resources to increase their export and total trade. Models were developed to explore the effectiveness of aid as a promotional instrument for exports and total trade. Donor exports and total trade were expressed as functions of aid, per capita GNP of the recipient country, and aid from competing donors. The study showed that exports and total trade responded to total expected aid contributions and per capita GNP of the recipient countries. Also, all donors, but one, were maximizing the returns to aid, given the level of trade with recipient countries and will be reluctant to increase aid flows, given the current trade level.     

Can Fiscal Decentralization Alleviate Government Consumption Volatility?

This paper assesses the effect of fiscal decentralization on government consumption volatility using data for 97 developed and developing countries from 1971 to 2010. The results suggest that a higher degree of fiscal decentralization leads to lower government consumption volatility. This result holds for the sub-sample of advanced economies, while it is not confirmed for those less-developed. This mechanism seems to work mainly through a lower volatility of the non-discretionary spending, which typically belongs to the central government’s policy. We also confirm existing findings according to which country size lowers government spending volatility. Thus, given a minimum level of development, fiscal decentralization reforms can reduce spending volatility by distributing power to sub-central governments, particularly in smaller countries which are usually more prone to volatility.     

Implications of Exchange Rate Pass-Through and Nontradable Goods for International Policy Cooperation

This paper investigates the welfare consequences of international policy cooperation by simultaneously introducing the following three elements in a standard two-country general equilibrium model: (i) general degrees of exchange rate pass-through, (ii) nontradable goods and their sector-specific productivity shocks, and (iii) general weights on goods in Cobb–Douglas consumption indices. There are two channels for possible mutual welfare gains from policy cooperation: First, cooperation can compensate for insufficient changes in the terms of trade when the degree of exchange rate pass-through is intermediate. Second, countries can cooperate in reaction to shocks in the nontradable goods sectors. This second channel is revealed by deriving an analytical condition for welfare gains under full pass-through and this condition is characterized by the weights in the consumption indices and the variances of sector-specific productivity shocks. Numerical evaluation demonstrates that when the two countries are symmetric and equal weights on consumption goods are assumed, welfare gains from cooperation increase as symmetric pass-through elasticity increases, which implies that the second channel dominates the first, whose effect on welfare gains is nonmonotonic in pass-through elasticity.     

Aid and Public Finance: A Missing Link?

The present consensus in the literature is that foreign aid does not have the desired positive effects on economic development. This is due in great part to poorly performing public institutions in recipient countries. In order to understand better the causes of this undesirable phenomenon, we examine the relationship between multilateral foreign aid flows and recipient countries’ public finance systems. We construct a new indicator to assess the quality of public finance, the Public Finance Institutions Quality (PFIQ) Index. For our panel of 86 countries, we find that multilateral aid flows have a negative impact on recipient country PFIQ score, whereas exogenous improvements in public finance seem to attract more aid. These results provide insight into the “black box” of governance: failure to turn aid receipts into desired results seems partly attributable to multilateral aid, in its present form, not being suited to improving a country’s public finance institutions. However, international donor organisations do seem to reward exogenous improvements in quality and reliability of public finance systems.     

国际援助再分类及其对受援国经济增长的异质性影响

国际援助对受援国的经济影响在学界并没有一致的答案，文章从不同类型国际援助的影响具有异质性的角度再次探讨这一问题。文章的主要工作有两点：一是对援助类型的重新分类；二是根据新分类的援助，实证分析不同类型援助的异质性影响。首先，基于中观经济学对生成性资源的分类方式，文章提出资源配对援助法，将国际援助分为了商业性援助、开发性援助和公益性援助三类，并与经合组织债权人申报系统相衔接，建立了分类后的国际援助数据集。然后，在实证分析部分，分别研究了援助总规模和不同类型国际援助对受援国经济发展的影响。结果发现，援助总规模对受援国的经济正向影响显著。同时，开发性援助和公益性援助存在门槛效应和滞后性，两者都有显著的正向影响，而且开发性援助对受援国经济发展促进作用要强于公益性援助。     

Chinese exchange rate and price effects on G3 import prices

This paper explores the degree of price and exchange rate interdependence between China and the G3 (US, Japan and the Euro-zone) by undertaking a VAR based shock analysis. A GARCH framework is also employed to derive the conditional variances to uncover the extent of volatility transmission. We address two key issues. First as there have been concerns about low value-added cheap Chinese goods flooding G3 markets, we attempt to measure the impact of Chinese prices on G3 import prices. Second, we focus on the transmission of exchange rate shocks – a subject which we approach by examining shocks in China's bilateral exchange rate with each of these major trading partners (the US, Japan and the Euro Area). Our results indicate that reduced import prices from China are the channel through which aggregate domestic prices in the G3 remain depressed, while the impact of the RMB exchange rate with G3 currencies appears less powerful. This finding implies that the Chinese authorities’ RMB exchange rate policy is relatively unimportant and, in particular, that a revaluation of the RMB would not do much to reduce the US trade deficit. In terms of volatility spillover, the relatively flexible RMB exchange rate against the Euro results in RMB-EUR volatility having a stronger influence than the more tightly controlled RMB-USD rate on the volatility of Chinese export prices.
