A Vector Error Correction Model for Japanese Real Exports

Atlantic Economic Journal - Japanese exports did not immediately react to the depreciations of the yen after a change in the economic policy framework in 2012, with the launching of Abenomics. This...     

The elasticity of substitution as a proxy measure of economic integration

This study examines how the accession of Greece to the European Union affected the Greek economy. Transcendental production functions of agriculture, industry, and service sectors of Greece, Germany, and France were estimated and tested for structural stability. Based on two estimated parameters of sectoral production functions and the corresponding data on capital-to-labor ratios, sectoral elasticities of substitution were constructed as vectors of values, varying with time. It was found that the elasticities of the traded sectors, industry, and manufacturing converged. The elasticities of substitution of the nontraded sector service and the traded, but protected, sector of agriculture diverged.     

On the Gibson Paradox

This paper uses recent developments in the theory of nonstationary regressors to investigate empirical relationships previously taken to support the Gibson paradox, using quarterly data over the 1957:1–1994:4 period on nominal interest rates and prices for eight European Union countries—Belgium, Denmark, England, France, Germany, Ireland, Italy, and The Netherlands. Using the methodology suggested by Kydland and Prescott, it is shown that the (relevant) cyclical nominal interest rate—price level contemporaneous correlations are weak, thereby punching a hole in the Gibson paradox. Evidence is also presented, based on the integration properties of the data, that standard Gibson paradox regressions are spurious.     

Trade and GDP Growth: Causal Relations in the United States and Canada

Causal relations between the growth rates of exports, imports, and the GDP of Canada and the United States are studied using the vector error correction (VEC) model. Utilizing time-series annual data (1948-1996), Granger causality tests are performed within the framework of the VEC model. Bidirectional causality is supported for Canada from the foreign sector to GDP and vice versa. A weaker relationship between the foreign sector and GDP is statistically supported for the United States. These results are also supported by comparing the total trade (exports plus imports) shares to GDP of the two neighboring economies. The Granger causality tests suggest that Canada is a more open economy than the United States and more trade dependent.     

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.
