我国货币供应量、物价水平与经济增长之间关系的实证研究

针对我国2001～2010年季度数据,通过使用协整关系检验、格兰杰因果检验以及方差分解分析方法进行实证研究发现,长期内我国货币供给的变化与物价和产出的变化之间存在唯一的协整关系;同时存在一个单向的Granger因果关系:货币供给增长率是物价水平增长率的Granger原因,即长期内货币供应量仅对物价水平产生影响。最后根据实证分析结果对货币政策选择提出政策建议。

排污费征收与环境质量关系的实证研究——以江西省为例

研究排污费征收与环境质量关系是目前热点问题.本文采用1990-2012年度江西省数据,通过协整检验、格兰杰因果关系检验、VAR模型分析,对排污费征收与环境质量之间的关系进行了实证分析与检验.结果表明：从长期来看,排污费征收与工业废水和工业固体废弃物排放存在长期的协整关系,与工业废水、二氧化硫和能源不存在长期协整关系,排污费的征收是引起工业废水和工业废弃固体排放的原因.本文认为可以从进一步提高污染的收费标准、扩大排污费收费范围、实施差别排污费政策、加快完善排污许可管理制度等等来改善环境质量.

Interest Rate Liberalization and Economic Growth in Zambia: A Dynamic Linkage

Abstract: This paper examines the dynamic impact of interest rate reforms on economic growth in Zambia—using two models in a stepwise fashion. In the first model, the efficacy of interest rate liberalization is examined by regressing the interest rate on the level of financial deepening. In the second model, the causal relationship between financial depth and economic growth is examined by incorporating savings as an intermittent variable in the bivariate setting, thereby creating a simple trivariate model. Using the cointegration‐based error correction model, the study finds strong support for the positive impact of interest rate liberalization on financial deepening. In addition, the study finds that financial deepening, which results from interest rate liberalization, Granger causes economic growth. The results apply irrespective of whether the causality is estimated in the short run or in the long run. Other results show that: (1) lagged financial depth leads to further financial deepening; (2) savings and economic growth Granger cause each other; and (3) financial development Granger causes savings in the long run.

Currency Substitution and the Stability of the Demand for Money in East Asia

Abstract

This paper models and tests the stability of the demand for money in five East Asian countries—Indonesia, Malaysia, Philippines, Singapore, and Thailand—in the context of an open economy. The Johansen multivariate cointegration vector error correction analysis against quarterly data covering the period 1985:1–2001:4 was used. It was found that a stationary long run cointegrating relationship exists between broad money, real income, domestic interest rates, foreign interest rates corrected for exchange rate depreciation, and the expected rate of depreciation of the exchange rate. The results show that US Treasury bills rates and the foreign exchange rate vis-à-vis the US dollar play a significant role in the East Asian countries money demand relationship. This suggests that currency substitution vis-à-vis the US dollar may be an important consideration in the design and implementation of monetary policy in the East Asian countries. Furthermore, the results show that the Asian currency crises impacted the money demand functions negatively in these countries. CUSUM and CUSUMSQ stability tests show no evidence of parameter instability of the money demand functions in three of the five countries throughout the period under investigation.     

Causal Relationship between Domestic Savings and Economic Growth: Evidence from Seven African Countries

This paper utilizes cointegration and the vector error‐correction model (VECM) to explore the causal relationship between economic growth and growth rate of domestic savings for Congo, Côte d’Ivoire, Ghana, Kenya, South Africa, and Zambia. Specifically, three analyses were undertaken. First, the time series properties of economic growth and domestic savings were ascertained with the help of the augmented Dickey–Fuller unit root procedure. Second, the long‐run relationship between economic growth and growth rate of domestic savings was examined in the context of the Johansen and Juselius (1990) framework. Finally, a Granger‐causality test was undertaken to determine the direction of causality between economic growth and growth rate of domestic savings. The results indicate one order of integration [I(1)] for each of the series. The results of the cointegration tests suggest that there is a long‐run relationship between economic growth and growth rate of savings. The results from the Granger‐causality tests indicate that contrary to the conventional wisdom, economic growth prima facie causes growth rate of domestic savings for most of the countries under consideration.

Determinants of Real Chinese GDP 1978–2014

In 2014, the IMF reported that China became the largest economy in the world according to Purchasing Power Parity rates. This study aims to explain the Chinese economic miracle. It focuses on frequently suggested factors influencing China’s real gross domestic product (GDP), such as export promotion, exchange rate policy, and foreign direct investment (FDI). The paper employs the Bounds test of the autoregressive distributed lag (ARDL) model to test for cointegration. Once cointegration is established, Granger Causality is investigated using the vector autoregressive model and the Toda and Yamamoto (1995) method. Two different combinations of the real macroeconomic variables exports, exchange rate, imports, and FDI were employed to examine Granger causal relationships. All explanatory variables, except for the exchange rate, were found to have plausible relationships with GDP. The exchange rate and GDP relationship was unexpected; a Renminbi appreciation was associated with an increase in GDP. To investigate this paradox, a third ARDL model was estimated with exports as the dependent variable and the exchange rate, world GDP, and FDI as the independent variables. In this model, we found evidence of cointegration and a plausible relationship between real exports and the real exchange rate. Exchange rate devaluation increased exports and thus indirectly increased GDP. Such findings help to resolve the unexpected results. Nonetheless, according to the Granger causality tests the established statistical evidence is rather weak. We found that both the exchange rate and FDI are no longer strong drivers of economic growth in China.
