我国省级区域金融发展对经常项目的影响研究——基于货物贸易视角的分析

本文选取我国大陆31个省(市、自治区)2007年-2018年的面板数据,综合运用系统GMM和差分GMM估计方法,实证检验了沿海与内陆、沿边与非沿边、享受优惠政策高与低、金融控制强与弱等4类不同省区金融发展对经常项目余额的影响。研究结果表明:使用全部样本估计时,金融发展显著负向影响经常项目余额,这一结论经稳健性检验后依然成立。使用不同区域的子样本估计时,金融发展对沿海省区、非沿边省区、享受优惠政策高以及金融控制弱省区的经常项目余额的抑制作用较大,而在其他省区作用较小。因此,各地区应充分利用金融手段来调整进出口余额,以保证经常项目的持续平衡。     

Do flexible exchange rates facilitate external adjustment? A dynamic approach with time-varying and asymmetric volatility

This paper revisits the claim that flexible exchange rates facilitate external adjustment. While previous studies have used exchange rate regime as a proxy for exchange rate flexibility, in this study there is evidence of ARCH effects in exchange rate, and thus GARCH models are employed to estimate volatility. A dynamic panel data model is then specified, and the Arellano-Bond estimator and the Blundell-Bond estimator are employed to estimate the effect of exchange rate flexibility on the speed of adjustment of current account in a panel of 28 emerging and developing economies. There is robust evidence that flexible exchange rates indeed facilitate smoother adjustment of current account imbalances.     

How is suicide different in Japan?

This study investigates suicide rates among OECD countries, with particular effort made to gain insight into how suicide in Japan is different from suicides in other OECD countries. Several findings emerged from fixed-effect panel regressions with country-specific time-trends. First, the impacts of socioeconomic variables vary across different gender–age groups. Second, in general, better economic conditions such as high levels of income and higher economic growth were found to reduce the suicide rate, while income inequality increases the suicide rate. Third, the suicide rate is more sensitive to economic factors captured by real GDP per capita, growth rate of real GDP per capita, and the Gini index than to social factors represented by divorce rate, birth rate, female labor force participation rate, and alcohol consumption. Fourth, female and elderly suicides are more difficult to be accounted for. Finally, in accordance with general beliefs, Japan's suicide problem is very different from those of other OECD countries. The impact of the socioeconomic variables on suicide is greater in Japan than in other OECD countries.     

Terms of Trade Shocks and the Current Account: Evidence from Five Industrial Countries

What is the effect of shocks to the terms of trade on a country's current account position? The Harberger-Laursen-Metzler effect predicts that an adverse shock to the terms of trade will worsen the current account balance; in contrast, the prediction of intertemporal models of the current account is dependent on the duration of the shock. This paper examines several features of the terms of trade series of five OECD countries, and the relationship between terms of trade shocks and the current account balance. Median shocks to the terms of trade are found to be highly persistent, yet with a large transitory component, and to account for only a small share of the variability of current account balances in Canada, the United Kingdom, and the United States. In contrast, terms of trade shocks are found to account for a relatively large proportion of the variability of current account balances in Australia and New Zealand.

     

The Role of Current Account Balance in Forecasting the US Equity Premium: Evidence From a Quantile Predictive Regression Approach

The purpose of this paper is to investigate whether the current account balance can help in forecasting the quarterly S&P500-based equity premium out-of-sample. We consider an out-of-sample period of 1970:Q3 to 2014:Q4, with a corresponding in-sample period of 1947:Q2 to 1970:Q2. We employ a quantile predictive regression model. The quantile-based approach is more informative relative to any linear model, as it investigates the ability of the current account to forecast the entire conditional distribution of the equity premium, rather than being restricted to just the conditional-mean. In addition, we employ a recursive estimation of both the conditional-mean and quantile predictive regression models over the out-of-sample period which allows for time-varying parameters in the forecast evaluation part of the sample for both of these models. Our results indicate that unlike as suggested by the linear (mean-based) predictive regression model, the quantile regression model shows that the (changes in the) real current account balance contains significant out-of-sample information when the stock market is performing poorly (below the quantile value of 0.3), but not when the market is in normal to bullish modes (quantile value above 0.3). This result seems to be intuitive in the sense that, when the markets are performing average to well, that is performing around the median and above of the conditional distribution of the equity premium, the excess return is inherently a random-walk and hence, no information, from a predictor (changes in the real current account balance) is able to predict the equity premium.     

Deviation from Purchasing Power Parity: Evidence from Malaysia, 1973–1997

This paper presents an empirical test of Purchasing Power Parity (PPP) applied to the Malaysia ringgit for the period from 1973 (CPI) and 1984 (WPI) to 1997. Consistent with other research findings, it is detected that real exchange rate follows a random walk. Using multivariate cointegration methodology for the long-run relationship between real exchange rate and certain macro-economic variables, the study provides evidence supporting a long-run relationship between the real exchange rate and the current account balance and government spending, the last two variables have been not included in previous studies of this economy. The causality test between real exchange rate with the current account balance and government spending, however, does not receive support from the error-correction model. This suggests that both government spending and current account balance are not adequate to explain the changes in ringgit real exchange rate. The puzzle still remains unsolved.     

Patterns of Current Account Adjustment��Insights from Past Experience

Theoretical models on trade balance adjustment make a distinction between adjustment led by relative quantities (expenditure reduction) and adjustment led by relative prices (expenditure switching). Using cluster analysis on a set of over 70 current account adjustment episodes, we confirm the empirical relevance of this theoretical distinction, as quantity and price-driven adjustment cases can be distinguished in a statistically meaningful sense. We also identify a group of mixed cases, where both quantities and prices played a significant role in adjustment. Multinomial logit results suggest that economic fundamentals and business cycle positions prior to the adjustment have predictive power over the type of adjustment, i.e. whether the adjustment is quantity?C or price-driven. The exchange rate regime and the level of economic development (emerging market versus advanced status) do not have significant predictive power.     

On the determinants of national saving: An extreme-bounds analysis

On the Determinants of Saving: An Extreme-Bounds Analysis. — We use extreme-bounds analysis to examine the reliability of estimates of various determinants of national saving. Results from the cross-sectional data are discouraging, for few of the standard determinants identified in the theoretical and empirical saving literature can pass robustness tests. However, our panel analysis is much more encouraging. We found agricultural share in total output, public saving, budget balance, and the current account balance are indeed robust. Furthermore, when we applied a modified form of sensitivity analysis, we found that seven variables are very robust. Generally, the most commonly specified determinants of saving provide limited guidance in understanding and predicting saving behavior.     

Do Remittances Induce Inflation? Fresh Evidence from Developing Countries

The goal of this article is to examine the determinants of inflation in both the short run and the long run for 54 developing countries using a panel data set covering the 1995–2004 period. Apart from the commonly used economic determinants of inflation, we model the impact of remittances and institutional variables on inflation. Using the Arellano and Bond panel dynamic estimator and the Arellano and Bover and the Blundell and Bond system generalized method of moments estimator, we find evidence that in developing countries remittances generate inflation. The effect of remittances on inflation is more pronounced in the long run. Moreover, we find that openness, debt, current account deficits, the agricultural sector, and the short‐term U.S. interest rate have a positive effect on inflation. We also find that improvements in democracy reduce inflation.     

The dynamic linkages between current account deficit and budget balance deficit in the South Asian region

The issue of twin imbalances is at the forefront of fiscal policy concerns in the South Asian region, fuelled by an ever-going budget deficit and current account deficit over the last five decades. A standard approach is to assume a model in which budget balance influences the current account. We relax this assumption by using a panel data vector autoregression model comprising five South Asian countries. The results show that both budget deficit and current account deficit are mutually causative, which contrasts the unidirectional causality running from fiscal deficit to current account deficit found in prior studies. Further, this bi-causality relationship is also demonstrated in the impulse response analyses. Budget balance in South Asian economies responds positively to a one standard deviation positive shock in the current account balance. Likewise, external balance increases to a one standard deviation positive shock in internal balance. Higher fiscal debt impedes economic growth, which in turn impacts negatively on the budget balance. Our findings lead us to reject 'fiscal policy only' recommendations to address the twin deficits.     

Financial crises,Asian stock indices,and current accounts: An Asian-U.S. comparative study

This paper investigates the effects of financial crises-based exchange rate, real interest rate, and personal consumption expenditure on stock market indices and balances of current account in four Asian countries/areas, and the U.S. from 1997 to 2010. Results obtained from Sims's first-order DSGE representation suggest that two policy variables – changes in the exchange rate and changes in the real interest rate lagged by one quarter – act as stabilizers for contemporaneous changes in stock indices for Thailand, Malaysia, and the U.S., but as destabilizers for Taiwan and Hong Kong. However, changes in personal consumption expenditure lagged by one quarter only play a destabilizing role in Hong Kong. For contemporaneous changes in the current account balance, all three policy variables become destabilizers for all five countries except the one-quarter lagged change in real interest rate, which acts as a stabilizer in Malaysia.     

The Foreign Exchange Rate Exposure of Nations

Following the well-known approach by Adler and Dumas (Financ Manage 13(2):41–50, 1984), we evaluate the foreign exchange rate exposure of nations. Results based on data from 27 countries show that national foreign exchange rate exposures are significantly related to the current account and financial account balance variables of corresponding economies.     

Tracking the causes of eurozone external imbalances: new evidence and some policy implications

The paper assesses the contribution of key drivers of external imbalances in the Eurozone through the estimation of a panel-data Vector Autoregressive model over 1975–2011. Growth fluctuations, initially associated with demand booms triggered by unusually low interest rates, and later with demand contractions resulting from the crisis and policy adjustments, have played an important role in current account balance fluctuations. Changes in real exchange rates or unit labor costs have played a less important role. Demand shocks have contributed more to current account balance dynamics in the Eurozone periphery than in the core, whereas competitiveness has been a less prominent factor in the periphery but relatively more important in the core. Some broad policy implications of the findings for demand management in a currency union are discussed, including for fiscal policy coordination and macroprudential policies when union members face asymmetric shocks. The role of internal devaluation policies as a means of correcting external imbalances is also reassessed.     

An evolutionary algorithm for the estimation of threshold vector error correction models

We develop an evolutionary algorithm to estimate Threshold Vector Error Correction models (TVECM) with more than two cointegrated variables. Since disregarding a threshold in cointegration models renders standard approaches to the estimation of the cointegration vectors inefficient, TVECM necessitate a simultaneous estimation of the cointegration vector(s) and the threshold. As far as two cointegrated variables are considered this is commonly achieved by a grid search. However, grid search quickly becomes computationally unfeasible if more than two variables are cointegrated. Therefore, the likelihood function has to be maximized using heuristic approaches. Depending on the precise problem structure the evolutionary approach developed in the present paper for this purpose saves 90 to 99 per cent of the computation time of a grid search.     

人口结构变迁与经常账目失衡

世界范围内持续多年的经常账目失衡并不鲜见,以往研究多关注汇率和净出口的关系,而忽视了经常账目余额的另外一种属性——本国在外国的储蓄。本文尝试从人口结构变迁的角度对这一问题给出新的解释。本文通过构建包括幼年抚养比和老年抚养比的世代交替模型,理论分析和预测了：幼年抚养比上升会降低储蓄率、增加投资率,从而减少经常账目余额;而老年抚养比下降会提高储蓄率,增加经常账目余额;试图填补人口结构对经常账目影响的理论空白。接下来,本文利用1990年至2011年全球110个国家的强平衡面板数据进行实证分析,在静态和动态模型下均得到了与理论预测相一致的稳健结果。根据实证结果进行定量分析,本文发现中国抚养比的变化可以解释1990年至2007年间经常账目余额占GDP比重16.6%的变动。     

国际收支失衡下的中国货币政策——基于结构型VAR的经验研究

本文采用结构型VAR模型,旨在揭示中国国际收支失衡下货币政策的反应及其对于宏观经济波动的影响。我们发现:(1)针对经常项目和资本项目盈余,央行分别采取扩张性和紧缩性政策;(2)紧缩性货币政策会增加经常项目盈余,但对资本流动的影响很小;(3)净出口和净资本流入的正向冲击分别导致CPI的下降和上升。除净出口冲击降低CPI并伴随扩张性货币政策外,其他发现都符合理论判断,说明了央行针对国际收支失衡实施的货币政策的合理性。     

Determinants of external imbalances: The role of taxes, government spending, and productivity

This paper develops and estimates a dynamic optimizing model of the current account. The model focuses on real factors that determine the evolution of saving and investment and hence the external balance. Three types of shocks are at the center of the analysis: productivity shocks, shocks to labor input, and tax policy shocks. While our approach is in line with the real business cycle models of the current account, the distinguishing feature of the work is the application of econometric methods to time series data for a small open economy so as to directly estimate the parameters governing saving and investment under rational expectations restrictions.     

Interest rates, exchange rates and international adjustment: BW II dynamics

Recent attempts to explain the dynamics of adjustment of dollar exchange rates in the face of an anticipated deterioration of the US net international investment position have focused on portfolio balance models of exchange rate determination. In this paper we argue that such models are useful in understanding the behavior of dollar exchange rates with emerging market currencies but, consistent with a large body of empirical research, are not useful in understanding changes in the dollars value against the euro or the currencies of other developed countries. We conclude that portfolio preferences of governments of emerging markets provide the most plausible explanation for the persistent US current account deficit.     

Synthetic estimates for small areas: problems and results of a simulation experiment

The use of special estimation techniques to develop small area data is described using examples from Hungary. The focus is on the use of synthetic, or SPREE, techniques to increase the reliability of estimates of small-area characteristics. The techniques are tested using a simulation experiment. "Ten variables were selected from the 1980 population census. Their exact values were known. Four different synthetic estimators were tested and compared with the simple direct estimator. The ten variables were studied at both a fairly aggregated level (minor domains) and in great detail (mini domains). The simple direct estimator with the synthetic or composite synthetic estimators shows an improvement of average reliability of 40 to 50 per cent."     

Cross-Country Private Saving Heterogeneity and Culture

Motivated by the dominant role of cross-country heterogeneity in private saving in the creation of Eurozone imbalances over the past decade, we empirically investigate the determinants of private saving for a sample of 30 OECD countries over the period 1990–2010. In addition to standard macroeconomic variables, we include three country-specific cultural indicators, derived from the World and European Value Surveys. We find these three variables—thrift, trust and religiosity—to significantly contribute to the explanation of cross country saving heterogeneity both for the OECD group at large and for the Eurozone countries separately.
