Causal Relationship Between the Current Account and Financial Account

We demonstrate that a different causal relationship exists between the current and financial accounts in developed and developing countries. Using the Granger causality test, we clearly determine that the financial account is by and large responsible for the current account in developing countries; instead of financing the current account, the financial account thrusts the current account into an imbalance. In developed countries, however, the current account leads the way, and the financial account, as its name indicates, serves to finance a current account imbalance. This represents a forewarning that countries, which lack a sophisticated financial system to channel funds to proper locations, should not recklessly liberalize capital mobility.The author would like to thank an anonymous referee for valuable suggestions.     

Nontraded Goods and the Current Account

This paper investigates trade balance and current account behavior in response to various shocks when the economy produces and consumes both traded and nontraded goods. Previous analyses of these problems have interpreted current account behavior in terms of tension between parameters that measure intratemporal and intertemporal elasticity, respectively. This paper provides a simple general criterion for whether trade and current account behavior is perverse vis-à-vis the standard one-good model results: behavior is perverse if and only if traded and nontraded goods are Edgeworth complements; that is, if the cross-partial of the instantaneous utility function is positive.     

Expected Future Budget Deficits,the Real Exchange Rate and Current Account Dynamics in a Finite Horizon Model

This paper uses an optimizing open economy general-equilibrium model to investigate the macroeconomic effects of current and expected future budget deficits. It is shown that current and expected future budget deficits are positively correlated with the current account deficit, the capital stock and the real exchange rate, but negatively correlated with the domestic real interest rate and consumption, along the stable path approaching the steady state. The paper also demonstrates that the world real interest rate is positively correlated with consumption, foreign assets and the domestic real interest rate, but negatively correlated with the capital stock and the real exchange rate.

Meaningful Measures of the Current Account

Since the conventional current account uses cash-flow accounting, it is potentially devoid of economic meaning. Assessing foreign assets at market values and including expected transfers from abroad, this paper reports two measures of the external surplus that are grounded in economic theory. The first measure is the aggregate generational current account, annual differences in the sum of net foreign assets across all current and future generations. The second measure is the generational profile of net foreign assets in a benchmark year. These ideas are implemented with data from Korea.     

Productive Government Expenditures and the Current Account

This paper examines the effects of a change in government expenditure on the current account of the balance of payments using the optimizing approach. It is assumed that government expenditure is productive, and is regarded as an input in the aggregate production function. Based on the Blanchard–Fischer-type model, the paper demonstrates decisively that the current account deficit is due to a permanent increase in government expenditure.

Uncertainty and Investment Dynamics

This paper shows that with (partial) irreversibility higher uncertainty reduces the responsiveness of investment to demand shocks. Uncertainty increases real option values making firms more cautious when investing or disinvesting. This is confirmed both numerically for a model with a rich mix of adjustment costs, time-varying uncertainty, and aggregation over investment decisions and time and also empirically for a panel of manufacturing firms. These "cautionary effects" of uncertainty are large—going from the lower quartile to the upper quartile of the uncertainty distribution typically halves the first year investment response to demand shocks. This implies the responsiveness of firms to any given policy stimulus may be much weaker in periods of high uncertainty, such as after the 1973 oil crisis and September 11, 2001.     

收入不平等和中国经常账户失衡问题研究

文章通过理论分析和实证分析论证了收入不平等和中国经常账户失衡的数量关 系.首先构建了收入不平等和经常账户关系的两期模型,研究表明:低收入人群的跨期消费决策受到参照群体(高消费群体)消费外部性的影响,且这种影响随着收入不平等程度的增加而增加;同时,收入不平等对经常账户的影响与金融发展程度相关.随着收入不平等程度的增加,金融发展程度越高,经常账户越容易产生赤字;当金融发展程度较低时,低收入人群获得自由借贷的范围和水平受到限制,普遍推迟当前消费,进而导致经常账户盈余.文章还基于中国1980-2012年的统计数据,采用GMM估计方法对收入不平等和经常账户的关系进行了实证研究,结果表明:收入不平等是造成中国经常账户失衡的重要影响因素;收入不平等对中国经常账户的影响还受制于中国的金融发展水平.     

Sustainable and Excessive Current Account Deficits

Both the Mexican crisis of 1994–95 and the Asian financial crisis of 1997–98 have been preceded by large current account deficits run by the affected economies. External deficits are often assumed to play an important role in the propagation of financial crises in emerging markets. Policymakers are faced with a new challenge: that of resisting or accepting the large current account deficits that may result from heavy private capital inflows. This paper aims at providing some guidance:First, the Lawson Doctrine – according to which current account deficits that result from a shift in private-sector behaviour should not be a public policy concern – has been discredited by recent currency crises in Latin America and Asia. Second, define the size of current account deficits that should be sustainable in the long run. Third, the intertemporal approach to the current account does not provide a reliable benchmark to define when deficits become excessive. Fourth, large external deficits should be resisted if unsustainable currency appreciation, excessive risk-taking in the banking system and a sharp private spending boom are seen to coincide.     

Growth and the Current Account in a Small Open Economy

The authors provide a framework with which to analyze growth in a small economy with perfect capital mobility. The framework provides a diagrammatic representation of steady states that differs in interesting and important ways from the usual closed-economy Solow-Swan diagram. The authors use the key diagrams to illustrate the effects of changes in parameters such as the saving rate and productivity growth on steady-state values of macroeconomic aggregates. They compare the steady-state results for the open economy with those obtained using the more familiar closed-economy model. They illustrate the possibility of endogenous income growth.     

Threshold Effects in the Capital Account Liberalization and Foreign Direct Investment Relationship

This paper examines how capital account liberalization （CAL） affects foreign direct investment （FDI） inflows. Authors use a dynamic panel model encompassing 14 Middle East countries over the period from 1985 to 2009. The findings suggest that countries that are able to reap the benefits of the capital openness policy satisfy certain threshold conditions regarding the level of financial development and institutional quality. Thus to promote FDI, governments in this region should develop a set of policies that not only focus on financial openness, but also on the improvement of the financial system and legal institutions.     

The Dynamics of a Simple Relative Adjustment Cost Framework

This paper considers a capital accumulation model with the specific feature that adjustment costs depend on investment relative to the size of the capital stock. This framework has, beyond its plausible yet neglected setting, a number of interesting consequences. In particular, the possibility of multiple equilibria, of an unstable steady state and thus of a (`history dependent') threshold associated with concavity is surprising given a voluminous literature on multiple, history-dependent equilibria emphasizing non-concavities (or convexities).     

Is the Current Account Deficit Sustainable?

This article argues that Australia's savings behaviour relative to its investment opportunities ensures a structural current account deficit which is fundamentally sustainable. In fact considerable scope seems to exist for it to widen further, irrespective of fiscal tightening that has occurred during the last few years, without alarming macroeconomic consequences.     

Long-Run and Short-Run Behavior of Korea's Current Account

Recent research indicates that an error correction mechanism exists for current account imbalances in Germany, Japan, and the United States. In this paper, I test whether current account imbalances in Korea are also self-correcting. The Empirical results are ambiguous: while no conintegrating relationship can be detected, and error correction mechanism can. Using standard econometric methods, estimates of a small-scale macroeconomic model detect no effect of Korea's lagged net foreign claim position on any relevant variable. However, I do find that the current account is influenced by Korea's lagged net foreign claim position in a direct estimate of Korea's current account. [F32]     

The comovement between real activity and prices in the G7

In this paper, we study the short-run and long-run comovement between prices and real activity in the G7 countries during the postwar period using vector autoregressive systems and frequency-domain filters. We find several patterns that are robust across countries and time periods. Typically, the correlation coefficients at long-run horizons are significantly negative and the correlation coefficients at short-run horizons are substantially higher. Additionally, there is evidence of positive correlation at short-run forecast horizons for some countries.     

Relative Income and Investment Comparisons among OECD Nations

Cross-section and time series studies of convergence generally have led to opposite conclusions about the convergence hypothesis. The methodologies employed in these studies suffer certain conceptual or statistical weaknesses. In this study, an entirely different approach is taken. The analytics of convergence is modeled using differential equations and the necessary and sufficient condition for absolute (steady state) convergence is derived. While our results reject absolute convergence for the OECD nations in a differential equation-time only model and in a differential equation model with capital accumulation and time as arguments, we find evidence of relative convergence with a weaker differential equation model.     

论中国财政政策的经常项目跨期均衡效应

长期持续的大规模国际收支顺差表明中国经济存在一定程度的外部非均衡.基于流动性约束建立的跨期动态均衡模型与结构向量自回归模型的实证检验结果显示,财政政策作为中国重要的宏观经济政策,对经常项目跨期均衡具有一定的调控效果,尤其是当汇率政策退出时,财政政策的跨期效应会有所增强,且此时出口退税政策还在一定程度上具有稳定经常项目跨期波动的作用,所以中国应首先优化出口退税政策.此外,利率对经常项目跨期波动的影响比较稳健,表明中国可以通过调整针对流入资本的税收政策来改变资本借贷的实际利率水平,从而有助于实现经常项目跨期均衡.     

Current Account Imbalances and Real Exchange Rates in the Euro Area*

Global current account imbalances have been one of the focal points of interest for policymakers during the last few years. Less attention has been paid, however, to the diverging current account balances of the individual euro area countries. In this paper we consider the dynamics of current account adjustment and the role of real exchange rates in current account determination in the EMU countries. After controlling for the effects of income growth, we find the relationship between real exchange rates and current accounts to be substantial in size and subject to nonlinear effects. We find that real exchange rates can offer further insights, beyond the effects of the income catch‐up process, relevant to current account determination in the EMU.
