Abstract. We conduct a theoretical investigation into how financial reforms are affecting the long‐run economic performance of the partially reformed Chinese economy. In a model with a dual structure in commodity production and financial repression, allowing the co‐existence of a state banking system and an informal credit market and introducing heterogeneity in the transaction technologies of individuals, we examine the interactions between the state banking system and the informal credit market, and the effects of various measures of financial liberalization on individuals’ optimal portfolio choices and the macroeconomic aggregates.  相似文献

This study applies stationary test with a Fourier function proposed by Enders and Lee (2004 Enders, W and Lee, J. 2004. Testing for a unit root with a nonlinear Fourier function, Tuscaloosa, AL, , USA: Working Paper, Department of Economics, Finance and Legal Studies, University of Alabama.  [Google Scholar], 2009 Enders, W and Lee, J. 2009. The flexible Fourier form and testing for unit roots: an example of the term structure of interest rates, Tuscaloosa, AL, , USA: Working Paper, Department of Economics, Finance and Legal Studies, University of Alabama.  [Google Scholar]) to test the validity of long run Purchasing Power Parity (PPP) to assess the nonstationary properties of the real exchange rate for 20 African countries. We find that our approximation has higher power to detect U shaped breaks and smooth breaks than linear method if the true data generating process of exchange rate is in fact a stationary nonlinear process. We examine the validity of PPP from the nonlinear point of view and provide robust evidence clearly indicate that PPP holds true for almost African countries. Our findings point out their exchange rate adjustment is mean reversion towards PPP equilibrium values in a nonlinear way.  相似文献

The expansion of private labels, or store brands, has transformed consumer choice sets and competition in retail markets, prompting manufacturers to fight back with renewed pricing and product and promotion strategies to forestall further private label expansion. This article examines the spillover effects of television advertising on brand-level consumer demand for carbonated soft drinks (CSDs), including private labels, using a random coefficients logit model with household purchasing and advertising viewing Nielsen data. As in previous work, we find that although brand spillover effects significantly increase demand for CSD brands in the same company and undermine demand facing other manufacturers’ CSD brands, surprisingly, there are positive spillover effects on the demand for private label brands. This indicates that brand advertising is persuasive with respect to manufacturers’ brands but complementary with respect to private labels. Further results show that eliminating television advertising for CSDs would lower aggregate CSD sales as consumers migrate to other beverages, although private labels stand to gain, particularly Wal-Mart brands.  相似文献

China's economic development has been negatively influenced by its underdeveloped human resources since the People's Republic of China (PRC) was founded in 1949. The underdevelopment has been caused by various factors, such as China's highly centralized economic planning system and inadequate development in liberal and vocational education. In order to reverse the situation, many radical changes have been brought in since the economic reforms of late 1978. Focusing on the past and current human resource development (HRD) in China's manufacturing sector, this paper will identify the state of HRD in China, highlight changes in HRD during the period of transition to more market-oriented economic systems, and discuss its impact on business and management in China.  相似文献

In this study we empirically study the variance term structure using volatility index (VIX) futures market. We first derive a new pricing framework for VIX futures, which is convenient to study variance term structure dynamics. We construct five models and use Kalman filter and maximum likelihood method for model estimations and comparisons. We provide evidence that a third factor is statistically significant for variance term structure dynamics. We find that our parameter estimates are robust and helpful to shed light on economic significance of variance factor model. © 2009 Wiley Periodicals, Inc. Jrl Fut Mark 30:230–256, 2010  相似文献

Introduction:
Nowadays in this modern world, we should believe that economic development is affecting our lives. Economic communication and cooperation have already across the ethnic origin, skin tone and nationality. In this environment, trade exchange between different countries become even more ordinary, and the value of the currencies are seemed especially important. Therefore, we should now understand a phrase called PPP, which the full name is Purchasing Power Parity. It is a theory to research and compare the purchasing power relationshin hetween the different Currencies.  相似文献
